Calculating Risk in the Era of Obscurity: Reading Between the Lines of Security Advisories
Discover the gaps in security advisory patching and risk calculation, and learn how to improve the transparency and reliability of patch disclosure procedures for better enterprise security.
- The discussion starts with the observation that new systems are still being affected by Log4j vulnerabilities, despite patches being released.
- The analysis highlights the importance of understanding the risk calculation process, which is often problematic due to incomplete or faulty patches.
- The speaker notes that CVSS (Common Vulnerability Scoring System) is not sufficient to determine risk, as it only considers the severity of a bug and not the likelihood of being exploited.
- Incomplete patches can actually increase the risk of being exploited, making it important to assess the quality of patches and the effectiveness of patch management.
- The timeline for patch disclosure is often criticized, with some vendors taking too long to release fixes.
- Risk assessments are not static and can change over time, making it important for enterprises to continually re-evaluate their risk posture.
- The speaker highlights the importance of understanding the supply chain and the potential for incomplete or faulty patches to compromise security.
- A bug dump is not necessarily a rare occurrence, and CVSS does not account for memory corruption or sensitive data exposure.
- The speaker emphasizes the need for more transparent and reliable patch disclosure procedures, including providing clear information on exploitability and patch quality.
- The discussion also touches on the importance of handling patch-related issues and the challenges of patch prioritization.
- The paper highlights the need for better communication between vendors, researchers, and enterprises to improve the overall patching process.
- The speaker concludes by emphasizing the need for more effective and transparent patch disclosure procedures to improve the security posture of enterprises.
