Inadequate Monitoring

Category: Monitoring & Operational Security
Severity: High
MITRE ATT&CK Mapping: T1562.001 (Impair Defenses: Disable or Modify Tools)

Description

Insufficient monitoring of system activities, security events, and user behaviors, creating opportunities for malicious activities to go undetected and compromising incident response capabilities.

Technical Details

Attack Vector

• Monitoring system gaps
• Insufficient event coverage
• Poor alert mechanisms
• Delayed detection systems

Common Techniques

• Exploiting monitoring blind spots
• Operating during monitoring downtimes
• Avoiding monitored activities
• Timing attacks around monitoring

Impact

• Threat Detection Failures: Malicious activities going undetected
• Delayed Incident Response: Late discovery of security incidents
• Security Posture Degradation: Reduced security visibility
• Compliance Violations: Failure to meet monitoring requirements

Detection Methods

Monitoring Assessment

• Assess monitoring coverage and effectiveness
• Identify monitoring gaps and blind spots
• Monitor system performance metrics
• Analyze alert generation patterns

Security Analysis

• Analyze security event detection rates
• Monitor system behavior patterns
• Track monitoring system health
• Assess monitoring effectiveness

Mitigation Strategies

Monitoring Enhancement

• Implement comprehensive monitoring systems
• Use real-time monitoring tools
• Deploy automated alerting systems
• Monitor critical system components

Security Operations

• Implement security operations center (SOC)
• Use security information and event management (SIEM)
• Deploy threat detection systems
• Monitor security metrics

Real-World Examples

Example 1: Missing Real-Time Monitoring

# Inadequate monitoring system
class BasicMonitor:
    def __init__(self):
        self.events = []
    
    def log_event(self, event):
        # Only stores events, no real-time analysis
        self.events.append(event)
    
    def check_threats(self):
        # Manual threat checking - not real-time
        suspicious_events = []
        for event in self.events:
            if "failed_login" in event:
                suspicious_events.append(event)
        return suspicious_events

# Should implement real-time monitoring
class RealTimeMonitor:
    def __init__(self):
        self.events = []
        self.alert_thresholds = {
            "failed_login": 5,
            "privilege_escalation": 1,
            "data_access": 10
        }
    
    def log_event(self, event):
        self.events.append(event)
        self.analyze_event(event)
    
    def analyze_event(self, event):
        # Real-time threat analysis
        if self.is_suspicious(event):
            self.trigger_alert(event)

Example 2: Insufficient System Monitoring

# Basic system monitoring
def monitor_system():
    # Only checks basic metrics
    cpu_usage = get_cpu_usage()
    memory_usage = get_memory_usage()
    
    if cpu_usage > 80:
        print("High CPU usage")
    if memory_usage > 80:
        print("High memory usage")

# Should implement comprehensive monitoring
def monitor_system_comprehensive():
    metrics = {
        "cpu_usage": get_cpu_usage(),
        "memory_usage": get_memory_usage(),
        "disk_usage": get_disk_usage(),
        "network_activity": get_network_activity(),
        "process_count": get_process_count(),
        "active_connections": get_active_connections(),
        "failed_logins": get_failed_logins(),
        "privilege_escalations": get_privilege_escalations()
    }
    
    for metric, value in metrics.items():
        if is_anomalous(metric, value):
            trigger_alert(metric, value)

Example 3: Missing Security Event Monitoring

# Inadequate security monitoring
def handle_user_action(user, action):
    # Performs action without security monitoring
    result = execute_action(user, action)
    
    # Only logs basic information
    logger.info(f"User {user} performed {action}")
    
    return result

# Should implement security-focused monitoring
def handle_user_action_secure(user, action):
    # Pre-action security checks
    if is_suspicious_action(user, action):
        security_logger.warning(f"Suspicious action by {user}: {action}")
    
    result = execute_action(user, action)
    
    # Comprehensive security logging
    security_logger.info({
        "event": "user_action",
        "user": user,
        "action": action,
        "timestamp": time.time(),
        "ip_address": get_user_ip(user),
        "user_agent": get_user_agent(user),
        "result": result
    })
    
    # Post-action security analysis
    analyze_user_behavior(user, action)
    
    return result
