| Malicious software, such as Trojan horses, hacker tools, DDoS (Distributed Denial of Service) agents, and spyware, can establish a base on individual desktops and servers. Many of these are not detected by anti-virus software or even host intrusion detection systems. Once they have residency within the network, unauthorized users are able to breach firewalls and access sensitive data by assuming the identity of authorized users. The goal of running vulnerability assessment scans is to identify devices on your network that are open to known vulnerabilities.
Detection of unauthorized software is not a function of DNS. |
