What is incident response – 6 Key Steps for an Effective Incident Response Plan and Why You Need Incident Response PlanIlgaz Şenyüz
What is Incident Response ? – Incident response is a term used to describe an organization’s process to handle a data breach or cyber attack. It also attempts to manage the consequences of the “incident’’ Eventually, it aims to manage the incident most effectively in order to minimize its harmful effects on the organization. Therefore, an incident response tool is indispensable for any company. This tool should identify what poses a threat to the company and provide the methods to follow when a cyber attack occurs.
1) Who Is Responsible for Incident Response?
The incident response tool is run by a company’s cyber incident response team (CIRT), also known as the computer incident response team. This team mainly consists of IT staff, lawyers, members of human resources and public relations departments. In conclusion, CIRT is responsible for handling cyber attacks, data breaches, or any other harmful threat against the organization.
2) Why You Need Incident Response Plan
If your organization can not handle the incideent properly, it will become a larger problem that can ultimately lead to a damaging data breach, huge expenses, or system crash. Rapidly responding to an incident will help an organization to minimize losses, reduce exploited vulnerabilities, restore services and processes, and reduce the risks posed by future events. Hence, it is essential for your organization to have an already arranged incident response plan.
3) What is incident response – 6 Key Steps for an Effective Incident Response Plan
The most critical phase of incident response is to prepare for an inevitable security breach. Preparation will help your organization determine how well your organization’s CIRTs can respond to an incident and include policy, response plan, communication, documentation, identification of CIRT members, access control, tools, and training. Without sufficient preparation, your company will be vulnerable during a data breach or cyber attack.
Identification is the process by which incidents are identified quickly and ideally to enable rapid response and therefore reduce costs and losses. For this step of effective incident response, IT personnel collect events from log files, monitoring tools, error messages, intrusion detection systems, and firewalls to detect and identify incidents and their extent.
The main purpose of containment is to contain damage and prevent further damage from occurring. It is important to note that all the steps suggested by Keepnet Labs in the containment phase should be taken, especially in order to prevent the destruction of any evidence that may be needed for subsequent prosecution. These steps include short-term protection, system backup, and long-term limitation.
Eradication is one of the most effective incident response phases, which ideally involves removing the threat and restoring affected systems while minimizing data loss. Not only removing malicious content but also to ensure that affected systems are completely clean, are the main actions in the eradication phase.
Testing, monitoring, and verifying when putting systems back into production are the main tasks in this incident response step. This phase includes making decisions regarding time and date for restoring operations, testing and verifying compromised systems, tracking abnormal behavior, and using tools to test, monitor, and verify system behavior.
6- Lessons Learned
The lessons learned is a critical phase of incident response because it helps to guide and enhance future incident response efforts. This step provides organizations with the opportunity to update their incident response plans with the information they may have missed during the incident and complete documentation to provide future events. The lessons learned reports provide a clear overview of the entire event and can be used as training materials for new CIRT members or benchmarks for comparison during recap meetings.
Strengthen Your SOC Using Keepnet Threat Intelligence and Incident Responder Modules
Keepnet Threat Intelligence module scans the web and searches for signals and data that may represent your data security breach and a threat to your business. Hence, the constant vigilance that the Threat Intelligence module provides you reduces fraudulent activity by definitely shortening the time between a potential data breach and defensive response.
The incident response tool ensures that the right personnel and procedures are in place to effectively deal with the threat in the event of a security breach. According to the malware result, Incident Responder creates various attack signatures for alarm generation or blocking active security devices.
- Use Keepnet Threat Intelligence module to detect any potential data breach, and take the necessary measures against them.
- Use Keepnet Incident Responder to rapidly respond and remedy the threats efficiently.
By implementing these two, you will significantly strengthen your organization’s SOC.
