Vulnerability Management (VM) is consistently ranked among the top priorities for most information security organizations today. It is no longer an optional initiative for infoSec departments, with security compliance reviews and audits explicitly calling for vulnerability management as a necessary component of enterprise security. SANS lists ‘Vulnerability Assessment and Remediation’ as #4 in its list of Top 20 Critical Security Controls with the NSA assigning it a criticality ranking of ‘Very High’. While these are great reasons to get buy-in from executives, the true goals of a vulnerability management program must be more strategic to have any real impact on enterprise security. Vulnerability management programs must go beyond an audit checkbox and become a real weapon in your InfoSec toolkit for combating intruders and attackers.
In a series of Vulnerability Management Primer posts we are going to attempt to first outline and then detail the crucial aspects that enterprises MUST address to achieve this. Before we get into details about components and functions, let’s first attempt the impossible task of defining the scope for vulnerability management programs. When talking about vulnerability management it’s not uncommon to hear some wide-ranging questions.
Are you not just talking about a network vulnerability scanner?
Shouldn’t it include everything that is on my network?
When it comes to Vulnerability Management is there a difference between a workstation, a laptop, a phone, a printer and a wifi-enabled coffee machine?
What about my Web Application Scanners or DAST tools?
What about my SAST tools?
What about my Penetration Test program?
Where does configuration or firewall management fit in all of this?
In reality, the answers to these questions vary based on factors like program maturity, scale, organization etc. Unfortunately, organizations often take a tool-centric (rather than goal-centric) view to structuring InfoSec, resulting in several distinct programs, disconnected or barely-connected, working towards the same goal but not working together. It is fairly common that vulnerability management refers only to the detection and management of weaknesses that can be exploited by threats to your network assets. This is especially true for smaller organizations or programs that are in early stages of maturity. In its most regressive state, this devolves to just a network scanning tool and manual processes built around it.
Increasingly though, organizations are incorporating additional sources of information and building processes that successfully factor these in. These could be threat intel feeds, vendor bulletins, CMDB systems, HR systems, network traffic/segmentation, or anything else that provides ‘better context to / additional information about’ the data being analyzed. Some mature organizations are also combining their n/w and application security initiatives with the knowledge that, in a lot of cases, the effort to build context and collect intelligence can be successfully applied to security data coming from both of these distinct sets of tools. And then there are organizations that take this one step further and implement security orchestration to build automated response and remediation capabilities into their programs.
For the most part, we are going to stay away from discussions that are only relevant to a particular segment of the wide range of scope discussed above. Successful programs are built around goals and strategies (as opposed to around specific tools) and that is the discussion we want to have here. Whether you are analyzing network or application vulnerabilities, there is tremendous benefit to be had from incorporating other relevant sources of information. Whether you are doing remediation manually or through automatic orchestration you need to be able to define and implement strategies to be successful. In the next blog in the series we will discuss the key challenges vulnerability management programs must pay attention to. No matter where you land on the scope questions above you need a strategy for addressing these.

As breach remediation costs rise, seemingly in direct proportion to the number of attackers and attacks, what are you doing to manage your cybersecurity vulnerabilities and risks? Sufficient proof is easily found to reinforce that how you respond to threats and breaches can have a significant impact on your business. For example… The 2021 Ponemon Institute Annual Cost of a Breach Report found that the average cost of a breach rose 10% to $4.24M. The report also found that it took an average of 287 days to identify and contain a data breach. Even if you can handle the reputation hit of a breach, and even if your insurer agrees to cover a portion of the damages, do you want to be on the hook for millions of dollars in remediation and restoration costs? Prevention is easier and less expensive. Your data and intellectual property (IP) are often the most valuable assets you own, and as such are deserving of all the resources your team can muster for effective security vulnerability and risk management. Read on to learn more about the cyber risks to watch out for in 2022 and how you can plan and prepare for them. What types of cyberattacks can you expect? Counterintuitive, of course, because many organizations don’t expect their network to be attacked, any more than they expect it to contain dangerous vulnerabilities. You want to believe those events occur to others, not you. Right? Except competent hackers can infiltrate your network and steal your data and IP while remaining undetected. Ransomware attacks For several years now, ransomware attacks have been the fastest growing segment of cybersecurity breaches. Typically, criminals breach an organization and encrypt its data, rendering it unusable. Inaccessible data renders a firm unproductive and unprofitable for as long as the data remains inaccessible. The Colonial Pipeline ransomware attack, for example, led to the shutdown of the largest fuel pipeline in the U.S, which in turn caused fuel shortages across the East Coast. Criminals also threaten to publicize intellectual property (IP) and customer information, unless they receive a ransom. Although small-to-midsize businesses (SMBs) are at the most risk of criminal ransom demands, payouts can reach seven or eight figures. The highest ransom amount confirmed to have been paid is $40 million USD, by CNA Financial, in May 2021. Few SMBs can afford such extravagance. Cloud vulnerabilities The first researchers to discover and report on critical vulnerabilities in the cloud focused on Microsoft Azure infrastructure. In detailing the vulnerabilities, those researchers, who were with Check Point, “wanted to disprove the assumption that cloud infrastructures are secure.” And did they ever disprove it — the discovered vulnerabilities included those that received the highest possible score of 10.0. The qualitative severity ranking of a score of 9.0-10.0 is “critical.” The discovered vulnerabilities allowed malicious actors to compromise applications and data of those using similar cloud infrastructure. Firmware vulnerabilities Firmware vulnerabilities expose not only the major computer manufacturers, but also their customers. Undiscovered firmware vulnerabilities are especially damaging, because they grant criminals free reign over any network on which the devices are installed, leaving networks open until the vulnerability gets reported and patched. As the number of connected devices continues to grow, Internet of Things (IoT) security becomes increasingly important to analyze. Software vulnerabilities Applications contain vulnerabilities. According to Veracode, 75.2% of applications have security flaws, although 24% of those are considered high-severity. Common flaws include: Information leakage. Carriage Return and Line Feed (CRLF) injection. Cryptographic challenges. Code quality. Credentials management. Insider threats Insider theft and trading of secrets is another growing vulnerability area. As demonstrated by recent Cisco and GE breaches, employees with perceived grievances or bad intentions can choose to steal or wreak all kinds of damage on their employers’ data and networks. Carelessness and poor training also contribute to insider threats. Cyber threats to healthcare In recent years criminals have increasingly trained their sights onto hospitals, insurers, clinics, and others in that industry. A 2016 report by IBM and the Ponemon Institute found the frequency of healthcare industry data breaches has been rising since 2010, and it is now among the sectors most targeted by cyberattacks globally. Whether or not the reputation is deserved,healthcare industry computer networks are often considered soft targets by malicious actors. In 2021 Armis discovered nine vulnerabilities in critical systems used by 80% of major North American hospitals. Additionally, rapid health device adoption has increased the number of available targets for malicious breachers. Numerous healthcare devices suffer security flaws, including imaging equipment. Added together, those factors point to an increase in attacks on health care institutions. Attacks against health care networks threaten lives, not just productivity. Criminals might believe health care administrators are willing to pay ransoms faster to retrieve health data and help patients. That’s not always the case, as ransomware allegedly led to the death of an infant and was initially thought responsible for the death of a German patient. Individual medical data – name, birth date, blood type, surgeries, diagnoses, and other personally identifiable information – is particularly interesting to criminals. Once compromised, it’s impossible to restore patient privacy, just as it’s impossible to reverse the social and psychological harm inflicted. Forgotten cyber hygiene When IT professionals are always in stressful firefighting mode, they can’t be expected to remember everything. Sometimes patches fall through the cracks, and those vulnerabilities come back later to bite your network. Your IT department may be aware of old vulnerabilities, but just hasn’t gotten around to applying the necessary patches or closing open holes. A virtual private network (VPN) account that remained open, although no longer in use, was how criminals penetrated Colonial Pipeline. Employees had previously used that account to access the company network remotely. How can you uncover cybersecurity vulnerabilities and risks? It’s easy for consumers to learn what to watch for and what to avoid. They can download, for example, the Annual Data Breach Report from the Identity Theft Resource Center. You, on the other hand, have a network full of devices, endpoints, applications, and the weakest link in the security chain – users. Yes, you can lower the possibility of user negligence with cybersecurity training. Sure, you can find and read reports about currently existing threats. But without a comprehensive vulnerability management program that brings together every vulnerability scanning tool across your entire attack surface, it’s almost impossible to know what’s threatening your network right now. How do you find a vulnerability in YOUR cybersecurity and IT environments? Most organizations rely on several different vulnerability scanning tools to achieve full vulnerability assessment coverage over their IT environments. Most vulnerability scanning tools focus on only one specific aspect of your attack surface — network devices, web applications, open source components, cloud infrastructure, containers, IoT devices, etc. Vulnerability management teams are often left with the unenviable job of bringing these disconnected tools, and the incompatible data they deliver, together into cohesive and consistent programs. Deploying Brinqa vulnerability management software to perform vulnerability enumeration, analysis, and prioritization allows you to effortlessly synchronize and orchestrate the best vulnerability scanning tools for your environment. The Brinqa platform is designed for data-driven, risk-based cybersecurity solutions. Brinqa include risk models for cybersecurity problems like vulnerability management and application security, which are essentially data ontologies developed based on industry standards and best practices to represent these cybersecurity challenges in terms of data. Brinqa data models and risk scores are adaptive, open and configurable, and include not just vulnerability data, but also additional business context from within the organization, as well as external threat intelligence. For example, the data model automatically considers that if a server is internal facing, and it’s for testing code, then it’s going to differ in priority from an external facing server that is hosting an e-commerce site, and which contains customer personal data and information. Similarly, if external threat intelligence discovers that a particular vulnerability is suddenly very popular among malicious actors and is being used to affect breaches, the data model automatically computes and assigns a higher risk score to the vulnerability. First and foremost, we get you away from having to log into numerous different tools to bring all relevant information together and make it usable. Second, we streamline and automate your common vulnerability analysis, prioritization, and remediation use cases. That's the enormous benefit of Brinqa... The centralization is great, but once you start consolidating, enhancing, and contextualizing all of that data, you can provide a level of prioritization that takes your risk response to another level. Beginning with generic, out of the box rules based on best practices, the environment allows every Brinqa customer the flexibility to tailor analysis to their needs, basically giving them a self-service mechanism to implement their own cybersecurity service level agreements (SLAs). The default rules are like templates or starting points, which you adjust and configure as necessary. It is ineffective and inefficient to make decisions on an ad hoc, case by case basis, about what should be fixed and in what order. Once you implement Brinqa, your automated vulnerability remediation and cyber risk response processes deliver effective, consistent, and reliable results. Spend a little time (no money) to see how simple solving a major headache can be, with a free trial. Frequently Asked Questions: What is vulnerability scanning?

What does cybersecurity mean to your business? This might seem like an odd question, but how an enterprise responds to it can say a lot about the culture and practice of cybersecurity within that organization. There are many different ways to ask the same question — Which function does cybersecurity report to within the enterprise? Who are the internal clients of cybersecurity? Does cybersecurity leadership have a voice at the highest levels of corporate decision-making? There are 2 main schools of thought about the role and orientation of cybersecurity within the enterprise. The traditional school places cybersecurity within the Information Technology (IT) function of a business. In this model cybersecurity reports to IT, IT is the internal client for cybersecurity, and the CISO might report up to the CTO or CIO. It’s easy to see why one might make this association. IT and cybersecurity professionals often have similar or adjacent skillsets and overlapping educational and professional backgrounds. Both functions often deal with highly technical, specialized, and complex information and processes. However, the goals and KPIs of IT and cybersecurity are not only unaligned, they are often in direct conflict. The internal clients for IT are other business functions that essentially pay for the various technology assets (applications, servers, cloud instances, etc.) required to keep the enterprise running. IT performance is evaluated by how seamlessly, continuously, and cheaply they are able to deliver their services. IT doesn’t really have visibility into or an understanding of how these assets are being used by the business, what kind of data they process, which critical business functions they support. When cybersecurity comes to IT and tells them that a particular technology asset or part of the IT infrastructure has problems or weaknesses that could be exploited by malicious actors, they have to weigh the benefits — stopping a potential attack that may or may not happen vs. the costs — resources allocated to fix the problem, unhappy internal clients due to technology assets being unavailable during fixing, valuable time spent fixing and validating the issue. This is a hard sell and essentially amounts to self-regulation. A significant percentage of breaches exploit known vulnerabilities and weaknesses within an organization. Looked at from this lens, it's not difficult to see how such problems can go unaddressed. The modern school of thought recognizes Cybersecurity as its own independent vertical within the enterprise — like sales, marketing, HR, or any other function whose purpose is to help the business function and thrive. In this model, cybersecurity has various different business functions as internal clients, and the CISO might have a seat at the C-level table. Cybersecurity informs business stakeholders of the risks they face as a result of the technology infrastructure they utilize. The business stakeholders provide the context necessary for informed risk triage and collaborate with cybersecurity to identify which vulnerabilities or weaknesses pose the biggest threats to the part of business they own. These prioritized risks are then sent to IT for remediation. Cybersecurity provides guidance to IT on how they may remediate or mitigate a particular problem. Since risk remediation or mitigation is being driven by the business stakeholders, IT is incentivized to fix these problems. Risk-based cybersecurity is a methodology for program design that can help organizations put this modern approach into practice. By putting an emphasis on incorporating business context in the risk analysis process and data models, and by ensuring that business stakeholders are involved in the decision chain, risk-based cybersecurity programs provide a shared space where IT, business, and cybersecurity can come together and collaborate.
