Best Incident Response Use CasesAytun Çelebi
Best Incident Response Use Cases – Incident response is a well-organized approach used by an organization’s IT departments to combat and manage a cyber attack or security breach. The purpose of using incident response is to limit the damage and reduce the incident’s costs and recovery time. The people who handle the incident response are called the Computer Security Incident Response Team (CSIRT), and they follow the company’s Incident Response Plan (IRP).
More often, incident response helps to detect, investigate, and respond to data breaches and offers a variety of methods for threat identification, analysis, and remediation. Today, I will try to explain to you the 7 best incident response use cases.
1- Using Files Hashes to Locate IOCs
A detailed investigation about the incident cannot begin unless the CSIRT team finds Compromise Indicators (IOCs) that can be made using file hashes. After that, they search through Endpoint search, asset details, and related events. The endpoint full dump is then performed to find items that require fixes through endpoint isolation and file deletion. Also, whitelisting or blacklisting can also be used to classify good or bad objects.
2- Precise Detection
Every day, cyber threats are getting more complex, and they become more challenging to handle.
The incident response plan uses IOCs, user behavior, files, and network communication and corresponds them to precisely detect cyber threats.
3- Rapid Response
Access to endpoints can help CSIRT teams respond rapidly to threats through manual or automated remediation. Doing so can help them detect, block, and respond to Advanced Persistent Threats (APTs) before they damage the corporate IT infrastructure. A rapid response may include deleting files, changing IP addresses, or blocking network traffic, verifying files with Sandboxes, blocking users, or killing processes.
4- Investigative Forensics
One of the most crucial parts of the incident response plan is Indicators of Compromise (IOCs). They are recorded over time for forensics purposes. This allows your CSIRT team to understand and analyze possible cyberattack scenarios. Hence, IOCs must be effective to make forensic evidence acceptable in the courtroom.
5- Automated Incident Response
Automated incident response can help businesses handle threats quickly and give CSIRT teams more time to investigate and fix the cyber attack. As soon as suspicious activity is detected, the incident response tool automatically alerts and draws the analysts’ attention to the incident. For instance, you can automatically update or preconfigure your Firewall so that malicious IP addresses are blocked as soon as they are detected.
6- Organized Incident Response
Organized incident response is an approach used to align people, processes, and technology involved in responding to cyber threats and attacks. The purpose of doing this is to authorize CSIRT teams by knowing precisely what to do; when an event will occur; The right tools and processes are in place to respond quickly, accurately, and effectively to incidents.
7- Proactive Incident Response
Proactive incident response allows CSIRT teams or security analysts to proactively monitor security threats and discover security incidents or their signs before they even show up. Thus, it helps organizations to search for threats instead of using reactive approaches that work when the attack occurs, such as traditional security tools like antivirus programs.
Today’s cyber threat environment is evolving rapidly, and cyber threats are getting more complicated. If these threats are not handled properly and rapidly, the potential risk it poses to your company increases. Therefore, having a proper incident response plan is more important than ever. Keepnet Incident Responder will definitely help your company to build up a better incident response plan and strengthen your company’s security operations center (SOC).
