The term “Threat Response” refers to all technical and organizational measures used to detect, assess, contain, and remediate IT security incidents. In the software context, “Threat Response” mainly covers functions that translate security alerts into concrete countermeasures – from automatically isolating compromised systems to guiding incident response teams through structured workflows. The overall goal is to minimize the impact of attacks, reduce downtime, and ensure compliance with regulatory requirements.
Alert correlation and prioritization: Aggregating security events from different sources (e.g., endpoint, network, cloud) and automatically ranking them by criticality and risk.
Automated containment: Isolating infected endpoints, disabling compromised user accounts, or blocking suspicious IP addresses and domains.
Playbooks and runbooks: Predefined response procedures that specify step-by-step actions for certain threats – often partially or fully automated.
Orchestration (SOAR capabilities): Controlling and coordinating various security tools (e.g., firewall, EDR, e-mail gateway, ticket system) to trigger consistent responses across systems.
Threat intelligence enrichment: Enriching alerts with information from threat intelligence feeds (e.g., known indicators of compromise, tactics/techniques) to support faster, well-founded decisions.
Forensics and evidence collection: Gathering log data, process details, file hashes, and network connections to analyze the root cause and reconstruct the attack timeline.
Interactive case management: Creating and managing security cases with task lists, comments, ownership, and status tracking.
Real-time notifications: Delivering critical incident information to security teams via dashboards, e-mail, SMS, or collaboration tools (e.g., Teams, Slack).
Integration with ITSM and ticketing systems: Automatically creating and updating tickets in service management systems to embed security incidents into regular IT processes.
Reporting and compliance evidence: Generating reports on incidents, response times, and actions taken for management, audit, and regulatory bodies.
An endpoint detection and response (EDR) solution detects suspicious encryption behavior and automatically isolates the affected device from the corporate network.
A SOAR platform runs a playbook after a phishing alert: affected e-mails are removed from mailboxes, the sender is blocked, and a ticket is created in the ITSM system.
A cloud security service identifies unusual administrator activity in a SaaS application, enforces a forced password reset, and requires multi-factor authentication.
A SIEM system correlates multiple login attempts from unusual countries, classifies the pattern as a brute-force attack, and triggers temporary account lockouts.
An OT security solution detects suspicious traffic to a PLC in a production plant and initiates segmentation of the affected network segment to prevent tampering.
