Any system connected to RUnet can expect to be the subject of a variety of attacks. In many cases the goal of an attacker is to compromise a system, and then use that system as a base for attacks on other systems. All systems must have a system administrator. The system administrator is responsible for software installation and configuration, as well as monitoring the system for inappropriate use. One of the major responsibilities of the system administrator is to keep software up to date.
Most vendors issue security-related patches on a regular basis.
Systems that do not install these patches are much more likely to be compromised. This includes web areas, email lists, and regular meetings. Security issues are regularly discussed there. All systems at Rutgers are expected to control mail relaying. This is an issue only for systems that are running software that delivers email.
