NetFort LANGuardian is deep packet inspection software for investigating, monitoring, and reporting on user and network activity

In recent times there has been an increase in high profile security vulnerabilities. To name but a few:

Do you have the tools needed to detect attacks and malware on your network? Intrusion detection systems (IDS) and traffic analysis can be used to spot problems before they get out of control. Wireshark is sometimes a popular choice for focusing on a single client but what if you want to look at all traffic on your network?

NetFort LANGuardian - Network Security MonitoringNetFort LANGuardian is the industry’s leading deep packet inspection software for monitoring, troubleshooting, and reporting on network activity. It uses network packets as a data source and when linked to your Active Directory infrastructure you can find out who is responsible for problems on your network.

The optional LANGuardian security module provides an advanced network intrusion detection system (IDS) that enables real-time detection and alerting of malicious events that occur on your network. LANGuardian seamlessly integrates data from the IDS with traffic analysis data to provide an unprecedented level of visibility into activity on your network.

The LANGuardian IDS is based on Snort, an open-source network intrusion detection system that performs real-time traffic analysis on IP networks. The LANGuardian IDS takes Snort a step further by storing security events in the LANGuardian database. By integrating Snort into the LANGuardian architecture in this way, the security module extends the troubleshooting and network forensics capabilities of LANGuardian to cover back-in-time intrusion detection, while conforming to our core architectural principles of efficient storage and no performance impact.

The IDS rule-set is a combination of rules from:

  • Snort
  • ET Open
  • Bleeding Edge
  • NetFort

Configured via a rule-based language, the LANGuardian IDS analyzes network traffic using the signature, protocol, and anomaly methods of inspection. It can perform protocol analysis and content searching/matching, and it can detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, and OS fingerprinting attempts.

The LANGuardian IDS is configured with over 1600 signatures that include DPI for HTTP, RPC, and Telnet protocols. The signatures cover the events that typically occur on a network, for example:

  • File accesses
  • Database operations
  • E-mail activity
  • Web access

LANGuardian IDS signatures are updated hourly, and you can choose to apply the updates manually or automatically. You can also define your own signatures.
