In an era where cyberattacks are becoming increasingly sophisticated, possessing a Cyber Security Incident Response Plan (CSIRP) is no longer an option—it is a survival requirement for every organization.
The 2025 CSIRP, a collaborative product between the Vietnam Cybersecurity Emergency Response Teams/Coordination Center (VNCERT/CC) and CyberCX under the Australian Government’s capacity-building program, stands as the most comprehensive solution available today.
Why your organization needs the CSIRP 2025 document
A cybersecurity incident is an adverse event that compromises systems, violates security policies, and threatens the Confidentiality, Integrity, and Availability (CIA) of data. This document transcends theoretical guidance by providing robust execution tools:
Scientific Incident Classification: A ranking system from P4 (Minor) to P1 (Catastrophic) based on six impact areas: Legal, Operational, Financial, Health & Safety, Reputation, and IT/Network.
RACI Responsibility Matrix: Clearly defines who is Responsible, Accountable, Consulted, and Informed during a crisis.
NIST Standard Alignment: Direct references to NIST SP 800-61r2 for incident handling and NIST SP 800-86 for digital forensics techniques.
The 5-phase specialized incident response framework
The document details the incident response lifecycle through five logical steps, ensuring technical teams remain composed during a crisis:
Preparation: Establishing security controls and awareness training to mitigate initial impacts.
Identification: Detecting precursors and indicators from monitoring systems or user reports.
Triage: Assessing the scope and scale to identify the incident type (Ransomware, DDoS, Phishing, etc.) and prioritize handling.
Response: Implementing strategies for Containment, Eradication, and Recovery to return systems to a normal state.
Review: Completing post-incident reports and documenting lessons learned to improve future security posture.
Vital forensic investigation and evidence handling techniques
One of the most significant values of this document is its guidance on handling evidence for future legal proceedings.
Evidence type to collect | Detection tools & indicators |
Raw Disk Images, RAM Images | IDS/IPS Alerts, Firewall Logs |
Windows Logs, IIS, and Network Traffic | Web Proxy Applications (Urlscan) for link analysis |
Malware Hashes | Unusual file names, invalid SSL certificates |
Communication History with Attacker | Failed login attempts from suspicious foreign IPs |
Notably, the document provides in-depth investigation guides for DDoS attacks (categorized into logic and resource exhaustion attacks) and Ransomware, featuring support resources from reputable organizations such as No More Ransom, CISA, and AIS.
Expert incident response solutions
When an incident exceeds internal capabilities, coordinating with professional third parties is critical. Organizations are advised to establish encrypted out-of-band communication channels to prevent attackers from monitoring internal investigation details.
For assistance in building incident response playbooks or deploying professional SOC monitoring systems, enterprises can refer to IPSIP’s Comprehensive Cybersecurity Services.
Expert Advice: Do not wait for an attack to build a process. Download this document now and conduct annual drills to ensure every team member understands their role when "Hour G" arrives.
