Real-time security monitoring.

Real-time security monitoring is an essential aspect of any organization's IT security strategy. Cyberattacks and compliance regulations are the two primary drivers for IT security—data breaches and non-compliance to regulatory standards can cost your company a fortune. In some cases, cyberattacks can go undetected for months. This is why it's important to keep constant vigilance.

Real-time security monitoring provides visibility on what's happening in your network. It not only helps detect malicious activities as they're happening, but also can help prevent their occurrence based on the events leading to them.

What is real-time security monitoring?

Real-time security monitoring involves collecting information on, analyzing, alerting on, and keeping track of events for all important devices in an organization's network as they're happening.

Real-time security monitoring includes:

  • Acquiring and storing log data from network devices.
  • Monitoring and alerting about critical events as they happen.
  • Running vulnerability scans periodically.
  • Performing correlation on collected data to identify anomalies and attack patterns.
  • Conducting forensic analysis on real-time and historical events.
  • Keeping track of compliance requirements.

These activities are considered security information and event management (SIEM), and effective SIEM often requires a solution.

A SIEM solution provides real-time analysis and alerts of security events. This is achieved through dashboards—often customizable—that display charts, graphs, and reports in a user-friendly manner. It also provides customizable, real-time alerts.

SIEM solutions are equipped to perform forensic analysis, data aggregation, and correlation of events in real time. Since log data retention is important for analysis, SIEM solutions often employ some form of long-term storage mechanism as well. Another important SIEM capability is privileged user and service account activity monitoring, which is an essential part of most compliance regulations. These capabilities make SIEM solutions indispensible for real-time security monitoring.
