What is an Incident response?
Imagine a small company that operates a retail store. One day, the store manager notices that the payment system is acting strangely, displaying unusual error messages and slow transaction processing. Sensing a potential security incident, the manager refers to the Incident Response (IR) plan. The plan provides step-by-step instructions for assessing the situation, isolating the affected system, contacting the IT department, and informing the payment service provider. By following the IR plan, the store swiftly responds to the incident, mitigates any potential damage, and ensures customer data remains secure, reassuring both employees and customers.
How can you prepare your own Incident response plan
Assess Current Capabilities:
Evaluate the existing resources, systems, and processes related to incident response.If resources and expertise are limited, consider consulting with external experts like https://securedots.in/ or any other cybersecurity consultants who can provide guidance and support in developing the IR plan.
Remember, it’s important to adapt the IR plan to the organisation’s specific needs, size, and industry requirements. As the plan is developed, it should be communicated to all relevant parties and integrated into the organisation’s overall security strategy.
To build an incident response (IR) plan without an existing one, the IT admin or solo IT member can follow these steps. First, assess the current capabilities and identify any gaps. Then, refer to trusted resources to research best practices, such as the NIST Computer Security Incident Handling Guide, the SANS Incident Handler’s Handbook, and the ISO/IEC 27035:2016 standard. These resources provide comprehensive frameworks, guidelines, and practical insights for developing an effective IR plan. Once the plan is developed, establish communication channels, assign roles, conduct training, and regularly review and update the plan. Additionally, if resources and expertise are limited, seeking external assistance from cybersecurity consultants can be beneficial.

By combining these steps and utilising the provided resources, the IT admin or IT team can develop a robust incident response plan tailored to their organisation’s needs and industry requirements.
Identify Key Stakeholders:
Identify key internal stakeholders who should be involved in the development and implementation of the IR plan, such as management, IT staff, legal, and HR.
Create a Communication Plan:
Establish clear communication channels for reporting incidents and disseminating information.
Determine who should be notified and at what point during an incident.
Document Response Procedures:
Develop step-by-step procedures for responding to various types of incidents.
Include guidelines for initial assessment, containment, eradication, recovery, and post-incident analysis.
Assign Roles and Responsibilities:
Define the roles and responsibilities of each team member involved in incident response.
Ensure clarity regarding who is responsible for decision-making, coordination, and communication during an incident.
Establish Training and Awareness:
Provide training and awareness sessions for employees to familiarise them with incident response procedures and their respective roles.
Conduct drills or tabletop exercises to simulate different incident scenarios and test the effectiveness of the plan.
Document and Review:
Document the finalised IR plan and ensure it is easily accessible to all relevant stakeholders.
Schedule regular reviews and updates to the plan to account for changes in the organisation’s environment or threat landscape.
Having an incident response (IR) plan is like having an umbrella on a rainy day — it keeps you prepared and saves you from getting drenched in chaos when a security incident occurs. Don’t wait for the storm to hit, be proactive and have your IR plan ready to keep your organisation secure and shining even during challenging times.
