The information security officers focus on prevention of data. They build and adopt systems and tools to secure computers, data, and systems from phishing attacks, malware, and ransomware.
What is an incident response?
Incident response is defined as the response of an organization to a cyber attack or data breach. The aim of incident response is to reduce the damage and ensure a speedy resumption of normal activities.
Steps for creating your incident response plan.
An incident response plan provides a solid base for cybersecurity efforts. Here’s how to plan and get started.
– Assign clear responsibilities
Assign clear tasks to the responsible person who is going to oversee the development of an incident response plan. Their responsibility is to inform all the relevant stakeholders, gather input, and assign roles.
The drafting team of incident response plan should be responsible for detection, classification, notification, analysis, containment, eradication, documentation, and post-incident activity. The participation of senior management, attorneys, human resources, regulatory bodies, law enforcement, cyber consultants, and PR is also required for making an incident response plan successful.
– Define your risk tolerance
The second step you need to take while creating an incident response plan is to know your risk and define your risk tolerance. Identify the critical data and key functionality that is at risk and your company is required to keep secure. Try to identify the greatest risk for your company with the help of the stakeholders and make an alternative plan to deal with those risks.
– Classify events
After classifying the roles and identifying the risks, the next step is to classify the incidents. You can classify the incidents after developing it, which leads you to take an action.
One can lose control over confidential or restricted information after a high-risk incident. A medium risk incident refers to the installation of malware that leads to problems in the future. A low risk sometimes depends on the medium risks just like someone failing to adhere to the policy or by mistakenly clicking on a phishing link.
Classifying risks on time will help to prioritize and deal with them. The documented incident provides a base for investigation and audit.
– Set explicit instructions
After classifying incidents, it is time to set clear procedures that will explain the role of everyone in an incident. It covers everything from fixed timescales for investigation and the steps required to remediate the problem. Having explicit instructions removes doubt and wrong decision-making.
To uncover and contain an incident, it is vital to analyze the instructions that have been drafted as a part of the producers.
