Adopting a proactive defense strategy – namely one that anticipates future attack tactics and incorporates those into current cyber design – has become a key focus in government and is evolving into a leading security approach. While reactive alerts and traditional perimeter defense will still be necessary, countering to threats and attacks once they occur is simply no longer enough to protect sensitive government data and network architectures from ever-more creative adversaries. CISOs and other government security officers need to be active in network and application monitoring, recognizing security anomalies in their network to help identify threats before they form. Check out these three tips to help you become more proactive in your cyber defense posture.
- Know your audience
User Behavior Analytics (UBA) is one of the fastest-growing areas within enterprise security. With the right UBA technology, organizations can proactively defend themselves and react to known threats. Working along three broad categories, UBA defense technology should help agencies to make sense of the data in their massive stores as well as detect threats, prioritize them, and ease effective response. Solutions that don’t detect UBA threats aren’t very beneficial; tools that don’t help already overburdened analysts see incidents are also ineffective. Finally, UBA products should guide efficient and effective response to incidents, reporting on what was effected, who did it, and which accounts were used.

- Discover your endpoints
With over 140 million new, malicious threats released last year alone – bringing the total malware count to over 400 million – a clear, comprehensive strategy is a requirement to respond effectively to the rapidly-escalating threat landscape. Many of these attacks are aimed at endpoints, which themselves are increasing in number and scope today to include employee-owned devices, virtual machines, point of sale terminals, IoT devices, and even servers. However, by continuously, proactively monitoring a vast array of endpoints and their changes, agencies are able to develop a baseline and determine good vs. bad, authorized vs. unauthorized, and potentially high-risk changes. To be successful, an endpoint detection and response (EDR) plan should include: detection, containment, investigation, and remediation. The key to denying threats comes from comprehensive, proactive, continuous, and measurable solutions.
- Cover your tracks
While IT automation is increasing productivity and connectivity, especially when it comes to maintaining large facilities, it’s also generating an increased attack surface for hackers. The answer to these additional, unsecure layers, is a centrally managed security appliance that gives organization managers a more secure and simpler approach to protecting distributed control system networks. This defense-in-depth approach can segment and isolate connectivity to and between facilities. By going beyond simple inspection to add confidentiality, integrity, and availability protection to the data as it traverses the control systems network and other untrusted networks, managers can feel confident knowing all native and third party applications and data are secure.
Proactive defense is constantly evolving as agencies and organizations discover more about their networks, applications, and data. And as data and technology continue to transform and grow, a proactive defense strategy will become more and more necessary to protect critical architecture and information.
