It’s been a while since I’ve blogged. Things have been busy; Bitsight released a great report authored by yours truly on CISA’s KEV catalog. It’s really great if I do say so myself so I highly recommend going and giving it a glance.

More enterprise business leaders are beginning to understand that cybersecurity risk equates to business risk—and getting a clearer sense of the impact that cyber exposures can have on the bottom line. Consider the MGM Resorts and Clorox Company cybersecurity incidents that occurred last year. Both suffered considerable attacks, reportedly led by the Scattered Spider cybercriminal group, causing widespread business disruption and substantial financial losses.

Exposure management tooling can act as an excellent source of truth for cybersecurity leaders as they communicate risk up to the board level. The visibility and data streaming from exposure management solutions makes it easier for CISOs to track security performance over time, quantify improvements in security maturity levels, establish better financial quantification of cyber risk and ensure the organization's exposure levels match up with industry averages.

KEV! KEV! KEV! No, you aren’t standing outside a frat house while some college kids encourage their buddy Kevin to finish his beverage. Rather, it’s the sound of people extolling the virtues of the Cybersecurity and Infrastructure Security Agency’s (CISA) Known Exploited Vulnerabilities(KEV) Catalog.

Email is a well-known and widely used attack vector for malware distribution, phishing, and many other types of threats. For this reason, we evaluate certain email security practices as part of the Diligence category of risk vectors used to calculate Bitsight Security Ratings. On April 30, 2024, we added a new email security evaluation focused on the use of Domain-based Message Authentication, Reporting, and Conformance (DMARC) records.

One of the biggest benefits that an exposure management program can afford a security program is the power of risk-informed prioritization. When security leaders think of tooling like attack surface management (ASM) platforms, the most evident prioritization benefits come in the day-to-day tactical decisions of which threats and which exposures to have SecOps practitioners tackle first.

Supply chain cybersecurity and resilience have become pivotal across various cyber regulations, most notably NIS2 and DORA. In this blog, stemming from our latest ebook '5 Proven Strategies to Maximize Supply Chain Cyber Risk Management’, we will explore the reasons why resilience is a new mandate for CISOs today and, most importantly, how to secure the supply chain at scale—in line with evolving regulatory requirements.

Everyone knows that running outdated computer applications comes with annoyances and risks. An outdated application might face performance issues or just become slower than modern versions. It might face compatibility issues and have limited functionalities. It might lose technical support and even fail to meet current industry standards and regulations, which could put your organization at risk for non-compliance penalties and legal action.

At Bitsight, part of the core work of the Vulnerability Research team is to analyze new high-profile vulnerabilities and ensure we come up with ways to detect, at an internet-wide scale, who is affected by these. Sometimes - more often than not - the direct exploitation of these vulnerabilities is significantly intrusive, and thus we can not load a direct port of the publicly available Proofs-of-Concept onto our internet scanning infrastructure.

In light of the SEC's cybersecurity disclosure regulations in the US and NIS2 in Europe, corporate executives and institutional investors are facing a pressing need to align their expectations and improve understanding around cybersecurity risk management. The evolving threat landscape and regulatory environment highlight the importance of cohesive strategies to measure, prioritize, mitigate, and communicate cyber risks effectively.
