Feature: Anomaly Detection for Security

[mgd43b]

Overview

Detect unusual command patterns for security and awareness.

Problem

Compromised accounts or unusual behavior may go unnoticed until damage is done.

Proposed Solution

Anomaly detection:

• Detect unusual command patterns
• "You've never run this command before"
• "This command is unusual for this time of day"
• "This is a risky command you don't normally use"
• Alert/log suspicious activity

Examples

# Running unusual command
$ rm -rf /var/www/production
⚠️  ANOMALY DETECTED
   - You've never run this command before
   - It's a destructive operation
   - Unusual time (3:47 AM)
   - Not in your typical working directories

Are you absolutely sure? (type 'DELETE PRODUCTION' to confirm):

# Security audit
$ sdbh security audit
Found 2 anomalies in last 24 hours:
1. [High] rm -rf in unusual directory (3:47 AM)
2. [Medium] First-time SSH to unknown host (11:23 PM)

Technical Considerations

• Baseline normal behavior
• Statistical outlier detection
• Time-based analysis
• Risk scoring
