Service Summary

Symantec Endpoint Protection antivirus software is available for all university-owned systems.

Key Features

  • Antivirus and antispyware detection: Antivirus and antispyware scans detect viruses and other security risks, including spyware, adware, and other files, that can put a computer or a network at risk.
  • Personal firewall: The Symantec Endpoint Protection firewall provides a barrier between the computer and the Internet, preventing unauthorized users from accessing the computers and networks. It detects possible hacker attacks, protects personal information, and eliminates unwanted sources of network traffic.
  • Comprehensive malware and intrusion prevention: The Intrusion Prevention System (IPS) is the Symantec Endpoint Protection client's second layer of defense after the firewall. The intrusion prevention system is a network-based system. If a known attack is detected, one or more intrusion prevention technologies can automatically block it.
  • Proactive threat scanning: Proactive threat scanning uses heuristics to detect unknown threats. Heuristic process scanning analyzes the behavior of an application or process to determine if it exhibits characteristics of threats, such as Trojan horses, worms, or keyloggers. This type of protection is sometimes referred to as zero-day protection.
  • Kernel-level rootkit protection: Symantec Endpoint Protection expands rootkit protection to detect and repair kernel-level rootkits. Rootkits are programs that hide from a computer's operating system and can be used for malicious purposes.
  • Enhanced Live Update: LiveUpdate now supports the downloading and installation of a wide variety of content, including definitions, signatures, and whitelists to prevent false positives, engines, security patches for client vulnerabilities, and product updates.
