Sitemap File Discovery Access
This rule detects HTTP requests to URIs that contain both 'sitemap' and '.xml' (case-insensitive). This pattern is commonly associated with the discovery of sitemap files, which are used by search engines to crawl websites. Attackers or reconnaissance tools might access these files to map out a website's structure and discover hidden or unlinked pages, which can then be used for further attacks.
