DETECTION OVERVIEW

Web Directory Scan

Risk Factors

Anyone can accidentally discover a website directory by typing a modified URI into their web browser. Automated web directory scans are easy to run and have few disadvantages. Attackers primarily perform a website directory enumeration to gather information about potential targets or find other hidden new attack vectors.

The system might change the risk score for this detection.

Attack Background

Website directories that contain sensitive files or other interesting information can be revealed with website directory enumeration. First, an attacker sends HTTP requests to a host with several possible directory names in the URI, such as host/admin and host/logs. The server hosting the website returns a status code for each URI, providing the attacker with basic information about existing directories. For example, the attacker can ignore URIs associated with a 404 (Not Found) status code, and target URIs that returned other status codes for additional attacks.

Mitigation Options

Restrict server access to trusted clients only

Limit the rate of client requests to slow down scans

Block known scanners by their User-Agent or IP address
