The IRT will stay current with emerging threats and the latest incident response best practices through continuous learning, attending industry conferences, and engaging with cybersecurity communities.

5. Incident Reporting

All employees, contractors, and third-party personnel must promptly report any suspected or confirmed cybersecurity incidents to the designated incident reporting channels. Incident reporting channels will be clearly communicated and accessible to all personnel through security awareness training and official communication channels.

Prompt reporting of incidents is critical to ensure timely incident detection and response. Personnel must not attempt to resolve incidents independently but should immediately escalate any potential security incidents to the IRT or the designated incident reporting channels.

6. Incident Categorization and Severity

The IRT will categorize and assess the severity of reported incidents based on predefined criteria. Incidents will be classified according to their potential impact, level of risk, and sensitivity of the affected data. The severity assessment will help prioritize incident response efforts and resources appropriately.

The IRT will maintain a predefined severity matrix that outlines incident categories and corresponding response levels. This matrix will serve as a reference for determining the appropriate response actions for each incident category.

7. Incident Handling Procedures

7.1. Incident Triage and Analysis

Upon receiving an incident report, the IRT will promptly initiate incident triage and analysis. The team will conduct a preliminary investigation to determine the nature and scope of the incident. The IRT will assess the incident's impact on critical systems, data, and business operations to establish the appropriate response strategy.

The incident analysis will involve collecting relevant data and evidence, such as log files, network traffic data, and system snapshots. The IRT will use this information to understand the attack vectors, identify affected systems, and assess the potential risks.

7.2. Containment and Eradication

Based on the incident analysis, the IRT will take immediate

steps to contain the incident and prevent its further spread. This may involve isolating affected systems from the network, suspending user accounts, disabling compromised credentials, or blocking malicious IP addresses.

The IRT will work to eradicate the cause of the incident, removing malware, closing security vulnerabilities, and restoring systems to a secure state.

7.3. Evidence Preservation

During incident handling, the IRT will ensure the preservation of relevant evidence for potential legal and forensic purposes. Chain of custody procedures will be followed when handling digital evidence to ensure its integrity and admissibility in legal proceedings, if required.

The IRT will collaborate with legal and law enforcement representatives, if necessary, to determine the appropriate handling of evidence and ensure compliance with relevant laws and regulations.

7.4. Recovery and Restoration

After containing the incident and eradicating the threat, the IRT will focus on system recovery and data restoration. Priority will be given to critical systems and services to minimize disruption to business operations. The IRT will work closely with IT and system administrators to validate the integrity of restored data and ensure that systems are fully operational.

The IRT will continuously monitor the restored systems to detect any potential reoccurrence of the incident and promptly respond to any residual threats.

8. Incident Communication and Reporting

8.1. Communication Plan

The IRT will maintain a predefined incident communication plan that outlines communication channels, key stakeholders, and escalation procedures. The communication plan will include contact details for IRT members, senior management, legal counsel, public relations, and other relevant parties.

The IRT will designate a spokesperson responsible for communicating with internal and external stakeholders, including employees, customers, partners, regulators, and the media. Clear and consistent communication is essential to manage the incident's public perception and maintain stakeholder trust.

8.2. Incident Reporting
