An Overview of the Incident Response Process

Incident response is a process and not simply an isolated event. To be successful, incident response teams must take a synchronized and organized technique to handle any incident.

These are the five key steps that compose an effective incident response program:

Preparation is the key most crucial ingredient of an incident response program that works. Even the best people cannot effectively tackle an incident if there are no predetermined guidelines. A solid plan to support the team is a must. Development and documentation of IR policies, threat intelligence feeds, cyber hunting exercises and communication guidelines are the most crucial elements of this plan.

Detection and Reporting

This phase is focused on monitoring security events to spot, warn, and report on probable security incidents.

* To monitor of security events in the environment, the team can use firewalls, and set up data loss and intrusion prevention systems.

* To detect potential security incidents, the team should correlate alerts within an SIEM (Security Information and Event Management) solution.

* Before alerts are issued, analysts create an incident ticket, present initial findings, and lay down a preliminary incident classification.

* When reporting, there must be room for regulatory reporting escalations.

Triage and Analysis

This the step where the bulk of the effort in successfully scoping and understanding the security incident happens. Resources need to be utilized for data gathering from tools and systems for further examination, and also to identify compromise indicators. People must be knowledgeable and skilled in live memory and malware analysis, digital forensic and live system responses.

In collecting evidence, analysts have to concentrate on three core areas:

a. Endpoint Analysis

> Know the tracks the threat actor may have left behind

> Get artifacts necessary to the creation of a timeline of activities

> Conduct a thorough analysis of a detailed copy of systems from a forensic perspective, and let RAM go through it and identify main artifacts to find out the events that happened on a device

b. Binary Analysis

> Check into suspicious binaries or tools utilized by the attacker and document the abilities of those these programs.

Enterprise Hunting

> Go through presently used systems and event log technologies and determine the extent of compromise.

> Document all accounts, machines, etc. that have been compromised to control and neutralize effects.

Containment and Neutralization

This is among the most crucial steps of incident response. Containment and neutralization is based on the intelligence and compromise indicators found in the analysis stage. After system restoration and security verification, normal operations can continue.

Post-Incident Activity

More work must be done even after the incident is resolved. All information useful in the prevention of similar problems in the future should be documented. This step can be divided into the following:

> incident report completion to enhance the incident response plan and avoid similar security issues in the future

> post-incident monitoring to keep threat actors from reappearing

> updates of threat intelligence feeds

> identifying measures for preventive maintenance

> enhancing coordination within the organization for effective implementation of new security approach
