How To Detect And Patch A Log4J Vulnerability
IBM News, Thursday, August 31,2023
The Log4j vulnerability, or 'Log4Shell,' is considered one of the most catastrophic software flaws ever. Apache patched the flaw in December 2021, yet it remains a concern for security teams. In fact, it is still among the most exploited security vulnerabilities.
Log4Shell persists because the Apache Log4j 2 software package it affects is one of the world's most widely used logging libraries. Finding and fixing every instance of Log4Shell is expected to take a decade, according to the US Department of Homeland Security.
In the meantime, security teams can take some steps to speed up Log4Shell mitigation and remediation in their networks.
