Apache HTTP Server

TMA-APACHE-5.8

Ensure the HTTP TRACE Method Is Disabled

MédiaNível 1Automatizadaapache

Descrição

Use the Apache TraceEnable directive to disable the HTTP TRACE request method. The HTTP 1.1 protocol requires support for the TRACE request method which reflects the request back as a response and was intended for diagnostics purposes. The TRACE method is not needed and is easily subjected to abuse and should be disabled. TraceEnable must be set and every occurrence must be off (the default is on). Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.
