Filtering Known-Bad Messages Does Not Prove Detection Readiness

SCM feed for Latest

The article discusses the inadequacy of measuring cybersecurity effectiveness solely by block rates of known-bad messages. It argues that just because a system can block certain threats does not mean it is fully prepared to detect and respond to all potential attacks. This is a significant point for organizations relying on these metrics, as it may give a false sense of security. The piece emphasizes the need for a deeper understanding of detection capabilities rather than just focusing on how many threats are blocked. By doing so, organizations can better assess their true security posture and improve their defenses against evolving threats.

OpenSSL HollowByte Flaw Could Freeze Server Memory with 11-Byte TLS Requests

The Hacker News

A recently discovered vulnerability in OpenSSL, dubbed the HollowByte flaw, can cause unpatched servers to reserve up to 131 KB of memory for a tiny 11-byte TLS request that never arrives. This issue can lead to a denial-of-service condition, where the server's memory is tied up until the process is restarted. The problem was identified by Okta's Red Team, which reported it without a CVE or formal advisory. OpenSSL issued a fix for this vulnerability in June, but the lack of documentation means many users may remain unaware of the risk. As a result, organizations running affected OpenSSL versions should ensure they apply the update to avoid potential service disruptions.
