Data from Security Tools

(OBJ .)

Antivirus Software

• Protects systems against malware, including the following
  • Viruses
  • Worms
  • Trojans
  • Ransomware
  • Spyware
• Generates data like malware detection logs, system scans, and updates
• Data sent to SIEM for aggregation and correlation
• Helps identify security threats and system health

Data Loss Prevention (DLP) Systems

• Monitor and control data endpoints, network traffic, and cloud-stored data to prevent data breaches
• Generate data on potential data leak incidents, policy violations, and suspicious user activities
• Flags attempts to send sensitive data outside the organization
• Data sent to SIEM for timely corrective actions

Network Intrusion Detection Systems and Network Intrusion Prevention Systems

• Network Intrusion Detection Systems (NIDS)
  • Passively identify potential threats and generate alerts
• Network Intrusion Prevention Systems (NIPS)
  • Actively block or prevent threats from accessing the network
• Data includes the following
  • Detected threats
  • Blocked traffic
  • Network anomalies
• Sent to SIEM for identifying malicious activity, security vulnerabilities, and effectiveness of intrusion prevention measures

Firewalls

• Act as a barrier between trusted internal networks and untrusted external networks
• Filter incoming and outgoing traffic based on security rules (ACLs)
• Generate logs with data on allowed and blocked traffic, rule changes, and potential threats
  • Sent to SIEM for monitoring network perimeter security and identifying intrusion attempts

Vulnerability Scanners

• Identify security weaknesses, including missing patches, incorrect configurations, and known vulnerabilities
• Generate data on identified vulnerabilities, severity, and remediation recommendations
• Data integrated into SIEM to prioritize vulnerability remediation
  • Used to track remediation progress and verify the effectiveness of steps taken
