Introduction People might assume that computer systems have at least a basic level of security when they come out of the box. In general, this is unfortunately not the case.
Systems normally come installed with lots of default permissions and running services.
From a security stance, this is very bad. In fact, most break-ins can probably be attributed to improper default system settings. It requires a security-aware system administrator to check and modify these system settings to provide a fairly decent level of system security. Security probing together with scanning can help a lot here, to help lighten the burden and lessen the amount of required security knowledge. A good security probe will monitor your network, detect attacks and give some information on how to close this hole.
