| Error Type | Definition | Typical Symptoms | Business Impact | |------------|------------|------------------|-----------------| | | System flags benign activity as malicious. | Alert storms, repetitive “malware” detections on known good hosts, high analyst dismissal rate. | Analyst burnout, wasted investigation time, possible “alert fatigue” leading to missed real threats. | | False Negative (FN) | System fails to flag truly malicious activity. | Undetected lateral movement, data exfiltration continuing for weeks, post‑mortem discovery. | Data loss, regulatory fines, brand damage. | | True Positive (TP) | Correctly identified malicious activity. | Alert triggers, investigation confirms compromise. | Desired outcome – enables rapid containment. | | True Negative (TN) | Correctly ignored benign traffic. | No alert generated, normal operations continue. | Baseline performance. | | Mis‑classification (MC) | Alert generated but assigned to the wrong tactic/technique or severity. | An “initial access” alert labeled as “policy violation”, or a low‑severity rating for a high‑impact ransomware. | Inappropriate response priority, wasted resources. | | Contextual Drift (CD) | The same indicator toggles between benign and malicious based on environment changes (e.g., a legitimate admin tool used for remote admin). | Alert spikes after a new software deployment, but the tool is legitimate. | Confusion, policy violations, potential for “shadow IT”. | | Coverage Gap (CG) | Absence of monitoring for a critical vector (e.g., cloud workloads, IoT). | Successful compromise in an unmonitored segment, later discovered via forensic evidence. | Blind spots, compliance gaps. |

The consequences of intruder errors can be severe, including: | Error Type | Definition | Typical Symptoms

| Step | Action | Outcome | |------|--------|----------| | 1 | : All servers flagged as “Domain Controller”. | Rules can ignore known admin scripts on DCs. | | 2 | Baseline : Capture normal PowerShell command line arguments for a 2‑week period. | Learned that -EncodedCommand is rare (≤ 0.5 % of total). | | 3 | Rule tweak : Alert only when -EncodedCommand appears and the process launches from a non‑system account. | FP drops from 1,200 alerts/day → 45 alerts/day. | | 4 | Enrichment : Attach VirusTotal reputation to the script hash. | Immediate classification of known malicious payloads. | | 5 | Feedback : Analysts mark 3 remaining daily alerts as “legitimate admin task”. | Auto‑whitelist these specific command patterns. | | | False Negative (FN) | System fails
