Four Keys to Comprehensive Network Protection

According to IDC, worldwide security spending is expected to hit $133.8 billion by 2022, a CAGR of 9.2% over four years. Despite the year-over-year increase in cybersecurity spending worldwide, the volume and frequency of attacks has increased as well. Thousands of reported data breaches expose billions of records every year.

As your team works to combat the potpourri of change and risk across your entire network, consider evaluating your current security tools against these four pillars of comprehensive network protection: visibility, full-spectrum threat detection, threat hunting, and post-detection actions.

Network Visibility

Getting network visibility dramatically improves security by revealing the ground truth of everything happening on your network. Obtaining network visibility requires observing and/or capturing network traffic everywhere it flows. This requires the following:

  • Easy-to-deploy sensors to instrument a network for visibility
  • Ability to capture PCAPs for network truth
  • Network metadata to get human-understandable insight into what is happening on the network
  • Sharing of visibility data with 3rd-party tools through open APIs

Full-Spectrum Threat Detection

Organizations should employ an array of threat detection methods to optimize detection and minimizing false positives. These methods should include:

  • Signature-based detection
  • Behavioral-based detection
  • AI-based detection
  • MD5 hash matching

Threat Hunting

Threat hunting is the process of proactively looking for threats that have evaded detection by other methods. Without comprehensive data—on threats and in the absence of them—you can’t do threat hunting. Effective threat hunting requires:

  • A threat hunting data repository that is self-configuring, self-populating and self-managing
  • Goal-oriented system workflows
  • Analysis and visualization capabilities

Post-Detection Actions

When a real threat is discovered on a network, you need to respond quickly. A good network security solution should provide the following capabilities to speed time to response:

  • Prioritized alerting
  • Ability to stop network transmissions automatically (if it is an IPS)
  • Inputs to 3rd-party response and orchestration tools
  • Continuous improvement feedback

Employing network security tools that provide these four pillars of comprehensive network protection will empower you to defend your business. Bricata provides the critical technologies needed to protect a network as a single system. Bricata delivers:

Network Visibility to gain insight into what’s going on in your network;

Full-Spectrum Threat Detection to focus your attention on the most critical events; Threat Hunting to explore, investigate, and seek out network events and threats; and Post-Detection Actions to deal with threats once they have been discovered.
