Incident response is a methodical strategy for dealing with various types of cyber security problems, cyber threats, and data breaches.
Incident response adopts a question-and-answer approach to determine, contain, and minimize the costs of an attack or an unfolding incident. An effective incident response (IR) plan will help avoid future attacks, but when no vulnerabilities were exploited, it supports containment and one way only. Incident Handling's response to an incident includes logistics, communications, synchronicity, and planning.
This aspect of the Computer Security Incident Response Team's job is dealing with computer security issues. However, before carrying out those tasks, it is first crucial for the incident to be identified, recorded, and analyzed. It is during this stage that the role of TerraEagle’s SOC Analyst becomes important.
TerraEagle understands the importance of keeping things as simple as possible to prevent confusion during an emergency response.
TerraEagle advises who requires to be advised concerning a breach, what channels ought to be used, and what level of details needs to be provided. Rules need to be established on how to communicate these events to personnel, upper administration, those affected by the breach, law enforcement, and the media.
Don't reinvent the wheel. Always begin the incident response plan you develop from a template created by others in the industry and adapt it to its unique specifications. Our company can use the template provided by TerraEagle for incident scope, planning scenarios, logical sequences for incident response, team roles, notification, and escalation procedures.
Preparing a response to a possible security breach represents the most important part of incident response planning. TerraEagle is consulted for the plan, response plan strategy, communication, documentation, individual assessment, access control, tools for the response, and training materials.
Identification is the process through which incidents are monitored and, ideally, detected quickly. For this step of effective incident response, TerraEagle acquires incidents from log files, network monitoring sensors, error messages, intrusion detection systems, and firewalls.
Once an incident is triggered or recognized, it represents the primary goal of containing it. The aim of containment is to contain the harm and prevent additional harm, the more quickly they can be contained to limit harm.
For incident mitigation to be effective, it's critical that the threat is eliminated and the affected systems are restored back to their initial state. TerraEagle strives for assurance that it not only removes malicious content but also guarantees that the affected systems are functional and free of potential risk.
Conducting careful tests, monitoring, and debugging to confirm whether a system is still able to work properly are the crucial actions associated with incident response. The phase that's included in this process is making a decision about when, where, and how to restore the affected system, testing and verifying it, watching for abnormal behavior, and using tools for testing, monitoring, and validating system behavior.
Training is a major part of incident response because it helps to educate the staff about the next incident for preventive measures to be taken. This is the first measure that gives TerraEagle the opportunity to review previous emergency response plans as needed. Reviewing the lessons learned after a mishap can be advantageous during recap meetings for CIRT members, for training new team members, and as benchmarks for comparison.
