Credential theft attacks are a significant threat to organizations, often leading to data breaches and financial losses. RSA NetWitness provides a comprehensive platform to detect and respond to these threats effectively. This article guides you through the process of using RSA NetWitness to identify credential theft activities within your network.

Understanding Credential Theft Attacks

Credential theft involves attackers stealing login information such as usernames and passwords. Common methods include phishing, malware, and exploiting vulnerabilities in systems. Once credentials are compromised, attackers can gain unauthorized access to critical resources.

Setting Up RSA NetWitness for Detection

To effectively detect credential theft, ensure your RSA NetWitness deployment is properly configured. Key steps include:

  • Enabling detailed logging and data collection from endpoints and servers.
  • Configuring network sensors to monitor suspicious traffic patterns.
  • Integrating threat intelligence feeds for contextual awareness.

Monitoring Authentication Logs

RSA NetWitness can analyze authentication logs to identify anomalies such as multiple failed login attempts or logins from unusual locations. Look for patterns like:

  • Unsuccessful login attempts escalating in frequency.
  • Logins during odd hours.
  • Access from unfamiliar IP addresses.

Detecting Lateral Movement

Attackers often move laterally within a network after stealing credentials. Use RSA NetWitness to track unusual access to multiple systems from a single account, indicating potential lateral movement.

Using RSA NetWitness Features for Detection

RSA NetWitness offers several features to assist in detecting credential theft:

  • User Behavior Analytics (UBA): Identifies deviations from normal user activity.
  • Network Traffic Analysis: Detects suspicious data exfiltration or command-and-control communications.
  • Endpoint Monitoring: Tracks credential usage and access patterns on endpoints.

Responding to Detected Threats

Upon detecting signs of credential theft, take immediate action:

  • Isolate affected systems to prevent further damage.
  • Reset compromised user credentials.
  • Conduct a thorough investigation to understand the scope of the breach.
  • Implement additional security measures such as multi-factor authentication.

Conclusion

Using RSA NetWitness effectively requires continuous monitoring and analysis of network and user activity. By configuring the platform to detect anomalies associated with credential theft, organizations can respond swiftly and protect their assets from malicious actors.
