Apache HTTP Server

Apache HTTP Server at a glance

The Apache HTTP Server is one of the most widely deployed web servers, embedded in countless stacks. The project ships coordinated security releases across supported branches; as an internet-facing server, httpd advisories (path traversal, request smuggling and the like) deserve prompt attention.

For admins httpd usually comes from the distribution, which backports fixes — for critical advisories, check that your system pulls the patched package and that the service is restarted. Keep the module set minimal, review the configuration for exposed defaults, and terminate TLS with current settings. Before larger version jumps, check module and configuration compatibility. Track the branch's support window, and mind bundled copies of httpd inside appliances that update on their own schedule.
