How to ensure that information security is fit for purpose

RSA, the Security Division of EMC Corporation, has published a Security Brief providing strategic guidance for how organizations can transform SIEM (security information and event management) into a more effective platform for combating advanced threats. In the brief, entitled ‘Transforming Traditional Security Strategies into an Early Warning System for Advanced Threats,’ experts in cyber security from CSC, RSA, Terremark, and Verizon lay out the capabilities needed in next-generation information security strategies. Chief among these capabilities is ‘big data’ security analytics: using vast volumes of information from diverse sources to detect security threats based on behaviors and context, not signatures.

Government agencies and prominent corporations alike have experienced cyberattacks custom-designed to breach their defenses. In most cases, attacks were discovered only after damage was done. The Security Brief's authors contend that today's conventional security approaches, focused on the perimeter and anchored by SIEM systems, are designed for yesterday's threats and digital infrastructures, not the highly targeted advanced threats now facing today's more open, mobile, and connected organizations.

To detect and defeat advanced threats, organizations should consider an emerging class of security analytics system that can help them gain comprehensive, clear, and continuous visibility into complex IT environments. The Security Brief outlines four core capabilities of large-scale security analytics systems:

  • Pervasive visibility enabled by network packet capture and full session reconstruction
  • Deeper analytics to examine risks in context and compare behavior patterns
  • Massive scalability to handle the diverse deluge of information that's increasingly needed for complete situational awareness
  • Centralized repository for security-related data to help security teams analyze incidents in context and speed decision making about prospective threats.
