Networks change constantly and that creates problems for IT and security operations. Gaps open exposing pathways that attackers can exploit. While enterprise security controls like firewalls, intrusion prevention, vulnerability management and endpoint tools attempt to secure your network, breaches are still possible. The last line of defense must include constant analysis of daily exposures caused by exploitable vulnerabilities, common configuration mistakes, mismanaged credentials and legitimate user activity that exposes systems to risk of attack. Why are hackers still successful despite significant investments in security controls? Several factors make securing your network difficult, mostly because of overwhelming alerts, never-ending software updates and patches, and numerous vulnerability notifications. Those responsible for security must research and evaluate piles of data without context. Risk reduction is almost impossible.
