Log Data - 4.9

Summary

Notes:

Log Data

  • Firewall Logs: Logs of inbound and outbound traffic processed by the firewall, including details on allowed and blocked connections, which can be used for traffic analysis and security monitoring.
  • Application Logs: App-specific logs providing insights into application performance, user activities, errors, and any unusual behavior within the application.
  • Endpoint Logs: Logs from endpoint devices such as computers, mobile devices, and IoT devices, detailing device activity and security events, which help in tracking compromised endpoints.
  • OS-Specific Security Logs: Logs generated by the operating system, capturing critical security-related events like logins, system modifications, file access, and error messages.
  • IPS/IDS Logs: Logs from Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS) that provide information on detected threats, potential intrusions, and actions taken. These logs are often part of a Next-Generation Firewall (NGFW).
  • Network Logs: Logs related to network activity, including traffic patterns, errors, and performance metrics for infrastructure devices like routers, switches, and access points.
  • Metadata: Data that provides context to network communication, such as timestamps, source and destination IP addresses, protocol information, and other details that help track and analyze network traffic.

Data Sources

  • Vulnerability Scans: Logs generated by automated scans of systems and networks, aimed at identifying known security vulnerabilities or misconfigurations that could be exploited.
  • Automated Reports: Reports automatically generated from log data, often created by SIEM (Security Information and Event Management) systems, summarizing events, alerts, and security incidents. These reports typically require manual review for deeper analysis.
  • Dashboards: Real-time visualizations provided by SIEM systems or other monitoring tools, displaying up-to-date information about system health, security events, and performance metrics for quick access and analysis.
  • Packet Captures: Detailed recordings of network traffic at the packet level, used for in-depth analysis of network communications for troubleshooting, security investigations, and forensic analysis.
