Security Control Panel

The Security Control Panel allows administrators to configure security settings across the organization.

Security Profile

Choose an option to determine which alerts are generated on Sensors:

  • Low
  • Medium
  • High
  • Paranoid

Network Learning

Configure how the system:

  • Learns network activity
  • Detects anomalies
  • Applies security measures

Learning scope: Choose an option to determine what the system should focus on:

  • Adaptive Learning (default): This option establishes a global baseline for the protected environment, and notifies you about deviations. For instance, it triggers an alert if the system detects a node in the network with a previously unseen media access control (MAC) vendor.
  • Strict: This option establishes individual baselines for each network entity and notifies you of every change. For example, it triggers an alert whenever a new node appears in the network, or when two nodes start communicating.
Note:
The Strict approach is suitable for static networks, where the conditions rarely change and the nodes have fixed addresses. In all other situations, this mode will cause too many alerts, especially in networks with dynamic addressing. In a typical installation, we recommend that you use the default approach, and only enable the strict mode in zones with static addressing through the Zone configurations settings.

Phase switching: Choose an option to determine whether switching between learning and protection modes happens manually or automatically:

  • Manual
  • Dynamic

Current phase: Choose an option to determine whether the engine is learning or alerting on deviations:

  • Learning
  • Protecting

Learning phase duration: Specifies the duration before a baseline is finalized.

Process Learning

Process learning enables the system to detect and alert on changes in process behavior, enhancing security monitoring.

Alert on new variables: Select to raise alerts when the system detects the introduction of new process-related variables that were not previously observed.

Alert on new values: Select to generate alerts when the system detects a significant change in process values, indicating a potential anomaly.

Dynamic flow control: Select to trigger alerts when the system detects irregular patterns in cyclic access (read or write operations) to process variables.
