In a recent report conducted by Verizon on data breaches, the typical data breach is discovered only after many months. Worst of all, 70 percent of the time, an organization learns about a data breach from an outsider – not a good way to start your day when your company is featured in a New York Times data breach scandal.
Data breaches affect organizations of all sizes, and the intent of a breach can range from political to financial. Instead of being reactionary, it is important to have a system in place that can allow you to detect (internally) if a data breach is occurring.
Giving your security and your networking teams both a long-term and real-time view of network activity arms them with the ability to quickly detect network anomalies so data breaches can be stopped. In order to provide these items, you must implement network forensics.
Network forensics is the capture, storage, and analysis of network events. It allows your security or networking admin to go back in time on your network to see where a breach occurred and how it affected your network to solve the problem – it can also help with non-malicious network problems.
A good network forensics solution requires four key capabilities:
- Network Recording – capturing network traffic for forensic analysis
- Searching and Inspection – enabling administrators to comb through archived traffic for anomalies and signs of security events
- Trend Analysis and Baselining – characterizing network and application usage so that anomalies can be detected more quickly
- Reporting and Workflow – sharing traffic and analysis with security and IT experts to detect and stop attacks quickly, thereby reducing Mean-Time-to-Repair (MTTR)
If you are currently in the process of looking for a better way to protect your business against data breaches, network forensics should be a key element to your security strategy. However, before you purchase, be sure to have a network forensics solution that has all of the key capabilities listed above.
