Jumping on the bandwagon

 It seems everyone is making predictions for 2021. If we learned nothing else from 2020, it is that “The best-laid schemes of Mice and Men Often go awry, and leave us nothing but grief and pain, for promised joy” (Burns, Robert, 1785). Nevertheless, I will throw my two cents in the mix. 

 

For 2021 I see our cybersecurity challenges giving us four very distinct challenge areas: Cybersecurity Hygiene, Threat profiling and tuning, Insider Threat, and Advanced Persistent Threat (APT) activities. There will be an uptick and increasingly brazen attack pattern from various APTs around the world. Keeping up on our Cybersecurity hygiene will be paramount in our success in thwarting these onslaughts. Threat Profiling will prioritize the attacks for which we may most likely need to defend. We will require more visibility on insider activity and risk scoring to understand where information exposure may be (or becoming) at risk. And lastly, we must know our enemy and know where they strike, why, and how. As critical infrastructure upgrades the Operational Technology (OT) environments, it will open these up to more common IT-based attacks that may complicate the security of these (increasingly) connected environments. 

 

Cyber Hygiene

As most security professionals know, a large percentage of the nefarious events are “crimes of opportunity.” Access doors left open, S3 buckets mismanaged, application developers not accounting for proper IAM in the apps, etc. We should give special attention to strengthening our programs on IAM provisioning and de-provisioning, shoring up and strengthening our testing and change control process, and streamlining our processes that close the gap from “detection to remediation” in our vulnerability management programs. These process improvements coupled with the standard tool deployments of SEIM, NextGen AV, EDR, Rogue WAP prevention, and properly configured, maintained, and deployed firewall solutions will help defend against our mounting threat for this coming year. Oh, and, no matter your development lifecycle, implement an AppDevSec program now, not later, but now. 

 

Threat Profiling

The focus on our excellent cyber hygiene at home brings us to looking at a shifting landscape in the global APT threats. According to the latest analysis, these groups will (and have) stepped up their “brazen” attack attempts on their target audiences. Not without, however, notable intelligence on their “calling card” Indications of Compromise (IoC)


APT10

This Chinese group (also known as Red Apollo) seems to infiltrate “supplier” networks to either disrupt the supply chain, steal intellectual property for the Chinese Government, or leverage the supplier to dive deeper into the government or customer’s systems. Paraphrased from their FBI “wanted poster,” – APT 10 conducted extensive campaigns of global intrusions into computer systems aiming to steal, among other data, intellectual property and confidential business and technological information from more than at least 45 commercial and defense technology companies in at least a dozen states, managed service providers (“MSP”), which are companies that remotely manage the information technology infrastructure of businesses and governments around the world, and U.S. government agencies. The victim companies targeted by ZHU HUA and ZHANG SHILONG were involved in a diverse array of commercial activity, industries, and technologies, including aviation, space and satellite technology, manufacturing technology, oil and gas exploration, production technology, communications technology, computer processor technology, and maritime technology. In addition, for example, the APT 10 Group’s campaign compromised the data of an MSP and certain of its clients located in at least 12 countries, including Brazil, Canada, Finland, France, Germany, India, Japan, Sweden, Switzerland, the United Arab Emirates, the United Kingdom, and the United States.


APT41

This Chinese group (also known as Double Dragon) is transitioning from outright attacks to “hacking for hire” or “Criminal as a Service – CaaS.” Paraphrased from their FBI “wanted poster” – They face D.C. Grand Jury charges, including Unauthorized Access to Protected Computers, Aggravated Identity Theft, Money Laundering, and Wire Fraud. These charges primarily stemmed from alleged activity targeting high technology and video gaming companies and a United Kingdom citizen.

On August 11, 2020, a Grand Jury in the District of Columbia returned an indictment against Chinese nationals QIAN Chuan, FU Qiang, and JIANG Lizhi on charges including Racketeering, Money Laundering, Fraud, Identity Theft, and Access Device Fraud. 

 

These charges stem from their alleged unauthorized computer intrusions while employed by Chengdu 404 Network Technology Company. The defendants allegedly conducted supply chain attacks to gain unauthorized access to networks throughout the world, targeting hundreds of companies representing a broad array of industries: social media, telecommunications, government, defense, education, and manufacturing. These victims included companies in Australia, Brazil, Germany, India, Japan, and Sweden. The defendants allegedly targeted telecommunications providers in the United States, Australia, China (Tibet), Chile, India, Indonesia, Malaysia, Pakistan, Singapore, South Korea, Taiwan, and Thailand. The defendants allegedly deployed ransomware attacks and demanded payments from victims. APT41 is now taking orders for your desired level of “Christmas Chaos” ahead of the holidays. Okay, that was an editorial comment meant as a joke – but often, jokes are founded in truth.


APT34

This Iranian group (also known as Helix Kitten) targets similar entities as their sister team APT33 (also known as Elfin Team or Refined Kitten). APT33 reportedly targeted aerospace, defense, and petrochemical industry targets in the United States, South Korea, and Saudi Arabia. APT34 seems to take on a societal disruption focus, looking at organizations in the financial, energy, telecommunications, chemical industries, and critical infrastructure systems. They leverage “not so creative” methods to infiltrate their targets. They use things like Microsoft Excel macros, PowerShell-based exploits, and social engineering to gain access. This use of IT born attack vectors exacerbate the security challenges. The shift in OT within our critical infrastructure to more common IT components and networking will open the door to more common security exploits and challenges. 

 

This focus on critical infrastructure seems concerning to me. In 2002, I was privileged enough to be invited to participate in the “Digital Pearl Harbor” study at the Naval War College. The findings from the study were “downplayed” and “watered down” to not cause too much public concern, so shortly after 9/11, the results of the scenario testing, to most of the 90 or so participants, was nothing short of terrifying. I live by a theory that “surprise attack planning,” hard dates and target parameters notwithstanding, have flexibility in the project timeline.

 

So, my predictions are not all gloom and doom. My actual message for my prediction is that we now have an exciting opportunity to look closely and critically at ourselves. We need to evaluate our cyber hygiene, Threat profiling, our insider threat program (to include necessary operational checks and balances), and flesh out and drive our APT mitigation strategy and playbooks. “Knowledge is power” (Bacon, Francis, 1597). The more we know about ourselves, our defenses, our gaps, and our advisories, the more effectively we may spread our security budget.

So, now what?

In my recent posts, I have discussed the path to “getting there.” Getting Certified. Getting a Cybersecurity degree that lands your target job. Evaluating and getting products and technologies to help strive for more comprehensive security. So now what? What’s missing? 

 

I hinted at it, and Debbie Gordon brought it up on a comment before citing “Simulation as a standard for Cybersecurity” … Practical application, practice, and proficiency are what’s missing from the previous topics. As I’ve discussed, getting the piece of paper saying you did well in passing a course, class, test, or memorizing frameworks and theories may work to get the interview. Still, if that is the only arrow in your quiver, all the good intentions will not satisfy landing the role. “Doing” is the best way to hone proficiency. But resume bullets of positions that fit the “doing” category alone may not be enough. 

 

In the early days of the CMMI (Capability Maturity Model Integration), I had to remind my clients that “just because you have a very mature process (complete with documentation and continuous process improvement), does not mean it is “effective,” or, for that matter, even “good.” The same goes for citing your past work at an employer. While this shows “time in grade” it is, by no means, an indicator of proficiency. 

 

Proficiency develops through “live-fire events.” Events that may come from left field and have an urgency for which to address. The challenge here is that the limited opportunities to respond to an event or situation that requires grace under fire come infrequently and sporadic in many corporate environments. Much of the time, a responder or security professional will be looking at potential Indications of Compromises (IoCs) and running down rat holes. This activity is much different from quickly and efficiently employing a broad range of tools, interacting with many other departments, stakeholders, or cordoning off malware and bad actors. Preparedness from daily “run and maintain” tasks is where simulation helps keep the responders sharp. Simulation Standards apply to operational staff as well as job seekers. Skills atrophy is a real degradation of proficiency driven through a lack of (or opportunity to) practice. If the team is going through the motion of looking down rat holes for IoCs, it can be difficult to quickly swing into full alert mode when an actual event occurs.

 

For the job seeker, to add weight to the new degree or certification, I believe there is a real need to augment the experience, credentials, and formal study with simulation standards (and scoring). Being a “Missouri Boy,” I have lived my life insisting that folks don’t just “tell me how good they are” but that they “show me.” That is what simulation exercises will do. It will prove that not only will your potential hire, team member, or entire team be prepared to execute, but the simulation will also benchmark and score efficiency and effectiveness. 

 

Creating “muscle memory” is what regular simulation can accommodate. I will use a winter driving example. An inexperienced driver (or one that has not driven in the winter for a long time) may be taken off guard by hitting a patch of ice and losing traction. Contrarily, the season winter driver instinctively knows how to take corrective action and navigate the condition with ease. This “muscle memory” principle is the same for the cybersecurity teams as they go from the routine daily activities to stepping up to an actual event. By leveraging regular simulation exercises in a “live fire” environment, teams will gel under pressure and develop a “second nature” rhythm and cadence to their risk mitigation, remediation “dance” It comes down to the desired preparedness. Would you rather your Cybersecurity and IR teams be watching their feet doing the Box step or gliding across the floor doing the tango?

 

But you may be wondering if I have created a catch 22 here. I stated that “real events are few and far between,” then I said simulations should be “live fire” events. It is recommended, and, almost necessary, to look to third parties to help with the simulation standards and run a safe, isolated, real environment. 

 

An organization should look towards a Cyber Range to facilitate the environment, attack scenarios, and proficiency measurement. Unfortunately, this “Cyber Range” space is defined differently by different companies. It doesn’t mean the same thing and does not truly develop the desired team dynamics or proficiency. 

 

Years ago, when MSSPs were cropping up on the scene, there was a D.C. based company, RipTech, that shown brightly very early on. RipTech was a Managed SOC to which all other SOC providers aspired. Their secret was that they delivered what the client needed and expected. I have found a “RipTech like” provider in the emerging Cyber Range space, one that sets the bar for what a real Cyber Range, offering Simulation as a Standard, should be. If you’re intrigued by the concept of increasing proficiency, effectiveness, and developing repeatable “muscle memory” in your teams, I would be happy to assist. 

 

Please send me a note on LinkedIn to discuss simulation options. I will be glad to help define success criteria, custom needs, and desired metrics while making introductions for your organization to the “cream of the (Cyber Range) crop.”

The cream of the crop always rises to the top

 I have watched as the vernacular in cybersecurity normalized, abused, and over-used the term “best” in my career. Best is a very subjective term in cybersecurity. Best for whom, for what risk tolerance level, or for what threat profile? When looking at security products and technologies, the same “of what does ‘Best’ consist?” can be said. Features and benefits outlined in the sales cycle may taunt one into believing one technology is superior. When it is all examined with clarity of expectations for a specific organization, a deduction may become apparent that “Best for some may not be Best for the application at hand.” 

It reminds me of an analogy my friend and colleague made. When the VCR was building in popularity, features like multiple timer events could be programmed through a menu interface displayed on the playback TV screen (“on-screen display” or OSD). This feature allowed several programs to record at different times without further user intervention and became a central selling point. But, sadly, for those who paid dearly for these enhanced features, the reality was that most consumers only used “play,” Fast Forward,” “Stop,” and “Rewind.” 

This phenomenon can happen to any organization sans a formal Proof of Concept (POC) product selection process. This repeatable and customizable process will first document the expectations of the organization. Questions like “what challenge will this technology or tool solve?” and “what are the threat vectors, threat profiles, and typical methods of exploitation this technology or tool will need to address?” This shortlist of questions is, by no means, an exhaustive list. The initial questions should frame and define the custom scope and expectations for the applicability or organizational nuances. 

In my experience, I see many organizations put “technical blinders” on during their POC efforts. They look at the technical superiority or ease of the technical aspect of deployment. This technological focus is less than half the story. The “operational sustainability” quotient, frequently, is overlooked. Items like current staffing levels, current staffing training or expertise, Upkeep or maintenance, Operational configuration, Features that are being considered that may require a cultural adaptation, are there any HR or Legal concerns to a new capability? These and other organizational specific challenges need to be weighed and measured.

Once the comprehensive criterion is established and weighting is applied appropriately, the “cream of the crop” will naturally rise to the top. CISOs will want to consider leaving some scoring leeway to account for business-related differentiators such as “how easy with whom to work is the supplier?” or, of course, the almighty pricing (and negotiation experience).

From the Trenches (episode one)

Moving mountains cannot be accomplished alone. Most CISOs face similar questions when “pitching” an unfamiliar (to the organization) security control or technology. No matter which framework or standard the company has chosen to follow, the executive team will wonder “What do other organizations do?”, “Is this security challenge relevant to our industry?” and “Is this the most current or effective control or is there another way our peers have found for meeting the security challenge?” The next question may be “Is this an appropriate level of rigor for our size and market share?”

Being able to answer (or have these answers readily available) will be critical for a CISO in gaining support for budget and controls that will ultimately add to a CISO’s security control/capital, and potentially protect their job. 

Boiling the ocean is never a good strategy. Breaking down security controls into a “shortlist” of necessary practices (necessary for your organization, size, and organizational risk profile) has proven to be the most effective way to initiate the implementation of any security control or program. Picking the top 20 categories and their subsequent controls can give any organization a significant leg up with better control of the risk landscape while maintaining a manageable operational overhead.

Knowing how these categories and controls map to the major standards will further help a CISO in making the case for recommended improvements. Leadership should keep several things in mind; Risk tolerance and appetite (mapped to necessary practices), cultural perceptions and end-user experience, and operational sustainability. Compensating for these concerns during the initial request for resources, coupled with peer statistics and metrics, may help fully flesh out a business case for a process, policy, training, or technological improvements. 

From the trenches (episode two)

A ubiquitous question posed to any long time Cybersecurity practitioner is, “how can one get into the Cybersecurity field if they have focused on a non-technical or non-cyber related vocation?”

This question is complicated to answer on many levels because companies looking for Cybersecurity talent need people that can jump in and add value at the start. 

There are limited intern openings almost every spring, but these are impractical for a working professional with full-fledged obligations, and there’s a 50%/50% chance of a follow-on offer. 

Cybersecurity “Boot camp” is a recent advent. These boot camps typically prepare the student to pass an exam and rapidly obtain a certification. The challenge with this learning style is that a seasoned security professional will see right through the regurgitation of “frameworks” or “best practices.” The craft surrounding cybersecurity is the comprehensive understanding of balancing risk, business objectives and applying necessary practices commensurate to both. 

More and more outstanding Cybersecurity degree programs have been cropping up that provide a good “ground up” view of Cybersecurity. All with their unique focus and curriculum designed for various end goals for the students. Some focus on pushing the student towards industry certifications, some focus on audit, while others may take a deep technical dive. Many universities employ professors that are active practitioners like the Webster University Master’s Degree program. http://www.webster.edu/catalog/current/graduate-catalog/degrees/cybersecurity.html

The Webster University Master of Science (MS) in cybersecurity readies individuals for demanding positions in public and private sectors overseeing, operating, or protecting critical computer systems, information, networks, infrastructures, and communications networks. Students entering the cybersecurity program should know about computer systems, digital networks, familiarity with internet and wireless applications, and possess stable (high school algebra and exposure to trigonometry) mathematical and written and oral communication skills.

Graduates will be capable of explaining the essential principles and theories used throughout the field of cybersecurity. Graduates will also be capable of applying knowledge in the field of cybersecurity to analyze real-world problems. And finally, graduates will be capable of effectively integrating cybersecurity knowledge to propose solutions to real-world problems.

Yet one more shift is taking place in the Cybersecurity education landscape. Partnerships between businesses and universities have made higher education in Cyber more attainable to non-technical/Cyber career-changing learners. An exceptional program recently brought to my attention is the 100% Online NYU Tandon Bridge program. Students accepted to this program are indeed endowed with the tools to hit the Cybersecurity field running no matter their previous occupation of course of study. It is an affordable, flexible way for students with a non-technical background to attain admittance into select graduate programs.

https://engineering.nyu.edu/academics/programs/cybersecurity-ms-online/nyu-cyber-fellows

https://engineering.nyu.edu/academics/programs/nyu-tandon-bridge

Through the Tandon Bridge program, there are many STEM Master’s degree programs at NYU a student may shoot for, but, for the focus of this discussion, I will simply highlight the Cybersecurity, or Cyber Fellows M.S. and NYU Cyber Fellows program. 

The NYU Cyber Fellows provides a 75% scholarship towards tuition for the elite online Cybersecurity Master’s Degree. Thanks to generous industry support, this first of its kind program is offered for the affordable price of approximately $17,000 and includes access to a hands-on virtual lab, industry collaborations, an industry-reviewed curriculum, exclusive speaker events, and peer mentors. This multi-company industry input to the learning experience makes this program stand out. This junction between Higher Education and multi-company exposure is where “practical application” and operational sustainability skills are tested and shared.

By closing the financial gap through endowments and scholarships, Companies and Higher Education can help fill the cybersecurity talent gap through attention to structuring coursework along with affordability. If an employee can leverage a companies’ tuition assistance program, break into a desirable field, and have a minimal financial burden, the incentives for success are visible for all.

SEIM, SIEM and UEBA

A critical component of securing an enterprise is a tool to concatenate and correlate the data from events across security logs and tools. This grew from what we used to call "Log Aggregation, Correlation, and Normalization". As the volume of data coming through these systems became unmanageable, the evolution of the tools started alerting on event types. 

 The newer tools are classified as either a SEIM or SIEM. While both acronyms identify a tool's basic functionality, I offer up an opinion that there are subtitle nuances to the tools with which places them in one of the other categories. While used almost interchangeably, when we look at the acronyms separately we see that they have a focus that fits differing objectives

• SEIM stands for Security Event and Incident Management, while 
• SIEM stands for Security Information and Event Management 

While both tools would do the basics of a SIEM and gather security information from the various tools and logs necessary to have a holistic look at events across the security landscape, I believe a tool that falls into the SEIM category would have greater functionality in not only identifying events but include a workflow engine and evidence handling capacity to facilitate incident management across the enterprise. 

One point that often gets overlooked by technologists is that responding to Incidents across the enterprise includes many steps taken outside of IT that also need to be captured, recorded, and forensically held in a defensible chain of custody. This workflow may be managed by non-IT or IT Security personnel. 

This cross-organizational workflow is a piece that is evolving at best and has brought the rise of Security Orchestration And Response (SOAR) platforms. Most SEIM vendors are focused on User and Entity Behavior Analytics (UEBA) which includes machine learning of baseline activities and alerts on anomalous behaviors. This automation, while useful and expands the potential to capture more activities that may be suspect, it does not help the "defensibility" of responding to an incident beyond the technical realm. (more on UEBA in another post). As a consumer, I would want my SEIM to include a SOAR functionality or at the minimum an integration into my enterprise workflow management platform. There are so many disconnected choices out there (from SOAR at the Firewall, Standalone products, or some limited functionality in some SEIM solutions) 

I have found there are two types of SEIM vendors - Mature Security tools that are trying to incorporate UEBA; and Mature UEBA tools trying to snap on SEIM functionality. Both of which have their challenges. It really comes down to the applicability of the functionality in your particular use case. If your SOC team has the ability to "swivel chair" for event and incident management logging and tracking then the more mature UEBA tool, which may have some limitations in SEIM and SOAR functionality, may be acceptable.

Asset Managers Prepare: SEC Cybersecurity Sweep Audits Are a Reality

With the recent announcement by Jane Jarcho, National Associate Director for the Securities and Exchange Commission's Asset Manager exam program, that they “will be looking to see what policies are in place to prevent, detect and respond to cyber attacks,” as well as vendor access and vendor due diligence from asset managers, the SEC has ramped up their Cybersecurity Assessment program out of their Chicago office.

The practice of Asset management, broadly defined, refers to any system that monitors and maintains things of value to an entity or group. The context of Jarcho’s statements was directed towards Investment Managers.

Investment management is the professional asset management of various securities (shares, bonds and other securities) and other assets (e.g., real estate) in order to meet specified investment goals for the benefit of the investors. Investors may be institutions (insurance companies, pension funds, corporations, charities, educational establishments etc.) or private investors (both directly via investment contracts and more commonly via collective investment schemes e.g. mutual funds or exchange-traded funds).

The new focus is to try to "require" asset managers to disclose Cybersecurity breaches. The focus on cyber events (which has traditionally been "guidance" but is now being pressured to become "rule") is being prepared to meet the registration filing process for "material changes" as described in the SEC guidance for Corporate Financial Disclosure, topic 2: Cybersecurity

From the SEC CF Disclosure Guidance Topic Number 2: Cybersecurity 

Disclosure by Public Companies Regarding Cybersecurity Risks and Cyber Incidents

The federal securities laws, in part, are designed to elicit disclosure of timely, comprehensive, and accurate information about risks and events that a reasonable investor would consider important to an investment decision. Although no existing disclosure requirement explicitly refers to Cybersecurity risks and cyber incidents, a number of disclosure requirements may impose an obligation on registrants to disclose such risks and incidents. In addition, material information regarding Cybersecurity risks and cyber incidents is required to be disclosed when necessary in order to make other required disclosures, in light of the circumstances under which they are made, not misleading. 3 Therefore, as with other operational and financial risks, registrants should review, on an ongoing basis, the adequacy of their disclosure relating to Cybersecurity risks and cyber incidents.

The SEC is ramping up to perform Sweep Assessments. These are very targeted assessments against very succinct criterion. In this case the SEC is looking to see if Asset Managers are “doing the right things”. This comes as no shock or revelation to Cybersecurity professionals but Asset Managers have never really been held “accountable” for Cybersecurity in the past. Many Investment Managers strive to follow standards and industry accepted practices but they find they may not have such tight control over their Broker/Dealer networks. Alliance partner attestations of Cybersecurity control alone will not indemnify the brand and reputation following an incident. Due diligence and focus on standards becomes more and more important as the regulatory scrutiny increases.

Some of the items the SEC will be asking the Investment Managers to provide seems rudimentary to a Cybersecurity professional but may not be as readily accessible to some organizations. Getting an early start on identifying and compiling the pieces of evidence being asked for is key to not only a successful Cybersecurity focused Sweep Assessment but also to double check, validate or shore up a comprehensive Cybersecurity program. Having a third party assist in interpreting this evidence and ensuring the objective for the requests will ease the pain and confusion that may precede a formal assessment.

Some highlights from the SEC’s list of items they will be asking for are:

Relevant Policies and Procedures for:
Physical Device Inventory
Software platform and application inventory
Network Maps
Cataloging of External Connections to the network
Resource Classification based on risk
Logging capabilities
Written Security Policy
Risk Assessment Processes
Cybersecurity threats
Physical security threats
Systemic Cybersecurity roles and responsibility/accountability
Business Continuity Plan
Cybersecurity Ownership/Leadership (CISO or equivalent)
Cybersecurity Insurance maintenance and coverage
Cybersecurity Risk Management (adherence to Standards)
Cybersecurity Network Controls, testing and Staff Training
Engineering
Application Development
Configuration Standards
Distributed Denial Of Service resiliency
Data Retention and Destruction
Incident Response
Encryption
Audits
BCP and DR
Risks associated with Remote Customer Access and Asset Transfer Requests
Online Access
Identification Authentication and Access Management
User Credential protection
E-mail authentication
Risks associated with Vendors and Third Parties
Detection of Unauthorized Activity
Documentation of any incidents since January 1, 2013


There is much more detail they will be requesting to support the topics highlighted above. Bottom line here is that the SEC is looking to see that the organization is following industry accepted practices for Cybersecurity. Identifying supporting evidence will greatly reduce the frustration and churn that may result from being subjected to these sweep assessments. My advice is to get a jump on this expectation by identifying and validating the supporting evidence early.

CRO - Not just for City Planning?


Just a few short years ago “convergence”, in the Cybersecurity world, was bantered about as a single word descriptor for the union of physical and logical security. It was inevitable that we would want to correlate who is logged onto our network and when they arrived or left our buildings. From this revelation came the birth of the Chief Security Officer (CSO).

Another convergence is now the buzz in our journey toward Cybersecurity. It may very well be time for another revelation in that IR and BCP are naturally tied to one another in more ways than simply the occurrence of an event. From a Cybersecurity management perspective the big question is, does this beckon for the creation of a Cybersecurity Chief Resilience Officer (CRO)?

Back in the 1960’s and 1970’s, we went through great pains to ensure we backed up our systems on tape drives, disk packs, what ever we could to save our work, critical digital assets and livelihood from disasters. As we were called to employ our back up tapes we realized that the back ups were only part of the complex puzzle. We matured Disaster Recovery (DR) into Business Continuity Planning (BCP) and eventually, Business Resiliency Planning (BRP). This allows us to prepare a comprehensive set of decision making tools and plans for what might happen.

In the current threat landscape, data breaches and intrusions are more prevalent than ever. This has highlighted the need for a well planned, orchestrated and in some cases pre-scripted, incident response plan.  We need to define steps to take, what talent pools are necessary to respond, whom to notify and how to minimize the impact on our business. This necessitates that we prepare a comprehensive plan for what will happen.

Both BCP and IR planning are closely tied to business and technology, but both have very different resource needs. Successfully crafting these plans will take expertise from very different parts of an organization. The BCP is, by definition, a business plan. Therefore deep business prowess is required. The IR plan, on the other hand has deep technical aspects and legal ramifications that require very specialized IT and legal resources. The breadth of specialties necessary to develop and maintain these plans only compounds the challenge in keeping these plans truly alive in an organization. These plans need to feed and grow off one another.

An incident that requires attention may also have a direct impact on an organization’s ability to continue to do business securely. The fail over techniques or out of band data processing capabilities defined in a BCP may be appropriately invoked, or some notification trees developed in the BCP may very well be used in the IR plans.

Once the correlation between the planning processes are articulated, it become apparent that the convergence of the two disciplines augments the effectiveness of both.

I would venture to say that, with the current pace of IR that has become necessary, and the severity of impact to a given organization is realized we will start to see these two activities being headed up by a common lead within very large organizations (not just business, not just IT). So... maybe the CRO is not just for city planning anymore.

Zero Day


<this is an older blog from another site to which I post>

In a special report, the Washington Post focused on zero-day attacks and how they can happen.  In particular, the report spends time on two case studies.  The first focuses on the Shodan search engine, which, in 2009, took on a project to map the devices linked to the Internet and exposed the fact that many Industrial Control Systems (ICSs) were connected and incredibly vulnerable to hackers. The second case study is the 2010 Stuxnet attack on an Iranian nuclear processing facility in which an infected thumb drive located four zero-day spots in the ICS and caused centrifuges to self-destruct. Attacks such as these on ICS keep security experts up at night, for good reason.

ICSs are a complex problem because they were never designed or intended to be integrated with the business  network thereby potentially exposing the process controls to the internet.  They were built with an intentional “air gap” to provide security.  Now, however, as budgets decline almost universally and business are leveraging sustainability to drive operations efficiencies, businesses increasingly are adding “smarts” to their systems for buildings, fleets, plant operations, supply chains. These smart systems are often networked together as part of efforts to reduce workforces, lower costs and increase efficiencies. Because configuring these networks and the devices that comprise them is incredibly complex, the ICSs are inadvertently being connected to the Internet leaving them vulnerable to attack.

Security professionals who want to protect ICSs have a special challenge. The systems generally are decades old and do not allow for automated discovery of their configurations and interconnections. And yet, you can't protect what you don't understand.

Fortunately, the situation is not as impossible as it sounds. Choosing between business efficiencies and Cybersecurity is not necessary.  The answer to fighting zero-day attacks and malicious activity in this era of budget minimization is to "do the right things" when it comes to security. This means covering all the bases and remaining vigilant. It means being smart about smart systems. It means being creative.  For example, although traditional network mapping is not possible for ICS, security experts can leverage maintenance management systems and records to get a more clear idea of how the environment has evolved and where the subsystems are connected; to identify where the ingress and egress points in the system are located; and to perform periodic risk assessments of the system. Awareness of where the vulnerable systems are, and truly knowing how the components are connected, will shed light on potential holes in the ICS environment that may lead to exposure of vulnerabilities to the outside world. Performing assessments with a consequential risk basis will also help identify the systems, subsystems and components that wield the most impact if compromised. This allows the security professional to take action in mitigating these conditions. In the ICS arena, there are many times where simply remediating the vulnerability is not an option. Therefore, alternative mitigation strategies may need to be employed.

These steps (and a little creativity) can help to locate zero-day vulnerabilities, manage the risks associated with new and emerging “smart” systems, and derive savings by operating more sustainably.

So you want Cybersecurity Insurance?

Many years ago I was taught that one can only do three things with risk — eliminate, mitigate or transfer it. With the increase in attacks on automation technologies by those intending to compromise industrial control systems (ICS), such as supervisory control and data acquisition (SCADA) systems, and distribution control and process control networks, the majority of our collective attention has been on the first two areas of risk. Now, with the insurance industry beginning to cover cybersecurity risk, companies will find they can consider the third area, and transfer risk, if their cybersecurity is appropriate to their risk posture.
Lloyd’s of London recognized recently the need to address the potential for property damage or production loss due to a cyberterrorism attack. In February 2014, BBC News reported that the insurance company is denying coverage to power companies because of inadequate cyberdefenses. This emerging option for addressing risk will certainly put the onus back on owners and operators of ICS networks to know their risks and to also know how effectively their cybersecurity controls are working.
If companies find that this emerging option to transfer monetary risk is an attractive and viable solution to navigating the ICS cybersecurity labyrinth, they should also be prepared to look closely at their operating technology (OT) environments. It’s clear that, as insurance options mature, insurance companies will emphasize risk assessment and control validation.
ICS security pundits argue both pro and con when it comes to the value of conducting detailed risk assessments on OT environments. After all, business value is what we are here to protect, along with personnel and community safety. However, the ability to secure at least a portion of corporate peace of mind by transferring monetary risk to insurance policies should greatly augment the pro side of this risk assessment argument.
If companies want to transfer part of their risk, insurance will help drive the need to prove that their controls are in the right place and working. A formal and repeatable risk-assessment and standards-compliance process, such as the ICS Cybersecurity Assessment program we have pioneered with our current clients, will enable companies to make that risk transfer feasible.
