Old versions of software tend to be full of known vulnerabilities. Exploit old versions of unused software: Unused services tend to be forgotten, which means that they not get updated.Configure the service to distribute content: Unused services tend to be left with default configurations, which are not always secure or may be using default passwords.These are all TCP ports, and UDP ports identified by theĪcunetix network scanner are reported separately.Īlthough you do require ports to be open for users to connect to your services, you should restrict open ports, and ports exposed on the Internet to these services only. In this particular scan, these ports have been detected as being open on the server: 80, 1027, 135, 1457, 3389, 139, 8443. Any open ports detected during the scan will be reported as shown in the screenshot. One of the checks done in a network scan byĪcunetix Vulnerability Scanner is a TCP and UDP port scan.
