The Apache Log4j vulnerability continues to command significant attention throughout the public and private sectors. In a recent interview, the director of the US Cybersecurity and Infrastructure Security Agency (CISA) described Log4j as the “most serious vulnerability” she has seen in her decades-long career. On December 22, 2021, CISA, along with the Federal Bureau of Investigation (FBI), the National Security Agency (NSA) and international law enforcement partners, issued a joint advisory cautioning that malicious cyber actors are already scanning and exploiting some of the many thousands of vulnerable systems around the world.
In Depth
Security researchers predict that organizations will be contending with the vulnerability (and its fallout) for months to come. CISA created a dedicated Log4j webpage to provide an authoritative, up-to-date resource with mitigation guidance and resources for network defenders as well as a community-sourced GitHub repository of affected devices and services. These government resources are setting the baseline on reasonable security for Log4j response and, in essence, providing a potential roadmap for legal compliance.
