The Acunetix Port Scanner performs a port scan against the server hosting the scanned website. When open ports are found, Acunetix Web Vulnerability Scanner will proceed with network level security checks against the network service running on that port, such as DNS Open Recursion tests, badly configured proxy server tests, weak SNMP community strings, and many other network level security checks.
In Acunetix Web Vulnerability Scanner (WVS), port scanning is disabled by default. Port Scanning can be enabled from Acunetix WVS > Configuration > Scan Settings > Scanning Options > Enable port scanning.
The port scanner options can be found at Configuration > Scan Settings > Port Scanner. Here you can configure:
- The number of sockets used for scanning (i.e. the number of ports checked simultaneously)
- The connection timeout (in milliseconds)
- The ports that are checked for by Acunetix WVS.
Port Scanning in Acunetix Online Vulnerability Scanner (OVS) is done automatically as part of the network scans. Network Scans can be done on both web servers and perimeter servers.
