Application URI Configuration Changes
Detects when a configuration change is made to an applications URI.
What it detects
Detects when a configuration change is made to an applications URI. URIs for domain names that no longer exist (dangling URIs), not using HTTPS, wildcards at the end of the domain, URIs that are no unique to that app, or URIs that point to domains you do not control should be investigated.
MITRE ATT&CK mapping
False positives and triage
When and administrator is making legitimate URI configuration changes to an application. This should be a planned event.
