Incident Response and Post-Incident Management

The Cyber Resilience Imperative: Methodology and Intervention

In an operational context characterized by the increasing sophistication of Advanced Persistent Threats (APTs) and an expanded attack surface, the ability to execute a rapid and methodical response to a security incident is no longer an advantage, but a core requirement for business continuity and regulatory compliance.
Our specialized Incident Response (IR) and Post-Incident Management service is structured to minimize the impact of an adverse event through a rigorous process grounded in industry best practices and standards.

Phase 1: Incident Response (IR) - Intervention and Containment

This phase is dedicated to the operational management of the critical event, with the primary objective of limiting the spread of the compromise and preserving data integrity.

Core Activities

Technical Description

Preparation & Notification

Activation of the H24/7 Response Team. Validation of the report and preliminary criticality assessment.

Identification & Triage

Acquisition of Indicators of Compromise (IoCs) and forensic artifacts. Event confirmation and initial classification (e.g., Ransomware, Data Exfiltration, Business Email Compromise - BEC).

Containment

Implementation of network isolation strategies and logical segmentation to halt malicious activity. Development of a reverse Kill Chain to neutralize the attacker.

Eradication & Cleansing

Complete removal of persistent threats (persistence mechanisms, backdoors, malware). Sanitization of compromised systems and patching of known vulnerabilities used for initial access.

Recovery

Controlled return to system operability, ensuring verification of the absence of residual malicious activity and intensive post-recovery monitoring.

Phase 2: Post-Incident Management - Forensic Analysis and Risk Mitigation

Once the immediate intervention is concluded, the subsequent phase is crucial for an in-depth understanding of the attack and for strengthening the corporate security posture

Computer Forensics: Execution of a detailed forensic analysis on endpoints, servers, and network logs. Reconstruction of the complete chain of events (Attack Timeline), identification of the Root Cause Analysis (RCA), and determination of the exact scope of the breach.
Technical and Legal Documentation: Production of a comprehensive technical and legal report, essential for notification obligations (e.g., GDPR) and any legal actions. The report includes the final IoCs and the methodology of data acquisition.
Lessons Learned and Hardening: Conducting a debriefing to identify the procedural and technological gaps that facilitated the breach. Development of practical, concrete recommendations for system hardening, optimization of the Security Information and Event Management (SIEM), and update of Disaster Recovery and Business Continuity plans.
IR Plan Review: Update and simulation of internal Incident Response protocols to improve reaction times (Mean Time To Detect - MTTD and Mean Time To Respond - MTTR).

Our approach is methodical and data-driven, ensuring that every incident is not merely resolved, but transformed into a catalyst for elevating your cyber security maturity level.
