Secure how your servers connect to the Internet today

On December 10th, a vulnerability in the Java-based logging package, log4j, was disclosed, allowing attackers to execute code on remote servers. Cloudflare has updated its WAF to defend against this 0-day attack and recommends patching instances of log4j immediately. The attack exploits servers with unrestricted connectivity to the public Internet. To address this issue, deploying Cloudflare One can filter and log how infrastructure connects to any destination. Additionally, securing traffic inbound and outbound, protecting against malicious DNS queries, and inspecting and filtering HTTP traffic are crucial steps for network security.
