Security Incident Response

Overview#

The Argus Security Incident Response module provides a structured framework for detecting, investigating, containing, and resolving security incidents. With automated response playbooks, forensic analysis tools, timeline reconstruction, and chain-of-custody evidence management, security teams can respond to threats rapidly while maintaining the documentation required for compliance and legal proceedings.

Key Features#

Automated Incident Detection - Real-time threat identification and classification from multiple detection sources, including automated scanning, anomaly detection, threat intelligence feeds, and user reports.
Response Playbooks - Pre-configured and customizable workflows for common incident types guide responders through proven containment and resolution procedures. Playbooks support full automation, semi-automation, or manual execution with guidance.
Forensic Analysis - Deep investigation tools enable root cause analysis through network forensics, system log analysis, transaction tracing, and indicator-of-compromise identification.
Timeline Reconstruction - Automated event correlation across multiple data sources produces chronological attack chain visualizations mapped to industry-standard frameworks, enabling rapid understanding of incident progression.
Chain-of-Custody Evidence Management - Every piece of evidence is tracked with cryptographic integrity verification, custodian records, and purpose documentation to maintain admissibility for compliance and legal requirements.
Post-Incident Analysis - Structured post-mortem workflows capture root causes, contributing factors, lessons learned, and prevention measures, driving continuous improvement of your security posture.
Incident Reporting - Automated report generation for multiple audiences including initial notifications, status updates, executive summaries, technical analyses, and compliance reports.

How It Works#

Incident Lifecycle#

Security incidents progress through a structured lifecycle:

Detection - Threats are identified through automated scanning, anomaly detection, threat intelligence correlation, or manual reporting. Each detection includes severity classification and confidence scoring.
Investigation - The assigned responder gathers evidence, analyzes forensic data, and reconstructs the incident timeline. Automated tools correlate events across data sources and map activities to known attack techniques.
Containment - Response actions isolate affected systems, block malicious actors, and prevent further damage. Actions can be executed automatically through playbooks or manually with documented approval.
Eradication - The root cause is eliminated through patching, configuration changes, credential rotation, or other remediation measures.
Recovery - Affected systems are restored to normal operation with enhanced monitoring to verify the threat has been fully addressed.
Post-Mortem - A structured analysis captures what happened, why it happened, what was done, and what will be improved. Lessons learned feed back into detection rules, playbooks, and security controls.

Incident Categories#

The platform handles a broad range of incident types including:

Unauthorized access and data breaches
Malware infections and denial-of-service attacks
Insider threats and social engineering
API abuse and account compromise
Supply chain attacks and zero-day exploits
Configuration errors with security impact

Response Automation#

Playbooks define step-by-step response procedures that can include:

System and account isolation
Credential revocation
Evidence collection and preservation
Log analysis and threat hunting
Stakeholder notification
System restoration and monitoring

Each playbook step tracks execution status, duration, evidence generated, and success criteria, providing a complete audit trail of the response effort.

Impact Assessment#

Every incident includes an impact assessment covering financial exposure, operational disruption, reputational risk, compliance implications, affected assets, impacted users, and system downtime. This assessment informs severity classification and resource allocation decisions.

Compliance#

Incident response capabilities support compliance with:

SOC 2 - Incident management controls and response documentation
ISO 27001 - Information security incident management (A.16)
PCI-DSS - Incident response plan and breach notification requirements
HIPAA - Breach notification and incident documentation requirements
GDPR - 72-hour breach notification and incident record-keeping
NIST CSF - Respond and Recover function requirements

Availability#

Enterprise Plan: Full incident response platform included
Professional Plan: Core incident management; advanced forensics and automated playbooks available as add-on
