A Guide To Understanding the Basics of Incident Response

Incident response is considered to be an organized approach that addresses as well as manages the aftermath of any security breach taking place against an organization. 

This cyberattack goes by the name IT incident, computer incident, or security incident. The goal of this organization will be to handle the situation in such a way that will limit the damage while reducing the recovery time and cost. 

What Is The Incident Response?

The incident response activities are generally conducted by the organization's computer security incident response team. It is a group that is selected to include information security and general IT staff as well as C-suite level members. IR are steps that are used to prepare for, contain, detect as well as recover from a data breach. 

What Is A Cyber security Incident Response Plan?

The incident response methodology includes a plan which is a document that outlines an organization's procedure, steps, and responsibilities towards the incident response program. This may include the following details.

How the incident response will support the broader mission of the organization. 

The approach of the firm towards IR activities in each phase. 

Maintaining the roles and responsibilities for the completion of IR activities. 

Making a communicative bridge between the IR team and the rest of the organization. 

Metrics to capture the effectiveness of the IR capabilities. 

The National Institute of Standards and Technology (NIST) has opined that there are four key incident response steps to IR. They are as follows, 

Preparation:

No organization can ever formulate an effective response effectively. So, one must put a plan in place to both prevent as well as respond to events. 

Detection and analysis:

The second phase includes IR to determine whether an incident has occurred, its severity, and the type of IR. 

Containment and eradication:

The purpose of the IR is to halt the effects of any incident that has taken place so that it cannot cause any further damage. 

Post-incident recovery:

The post-incident recovery is a lesson that has been learned in meetings involving all relevant parties. The goal of such a meeting is to improve security and how to handle such occurrences with efficiency. 

Top Threat Intelligence Platforms:

Following we have mentioned a list of organizations that have highlighted the IR response like a pro. They are as followed, 

• Anomali
• IBM
• CrowdStrike
• LogRhythm
• AlienVault
• EclecticIQ
• Blueliv
• IntSights External Threat Intelligence
• Computer security
• FireEye
• Security information and event management, etc. 

Importance Of Incident Response:

Many consider cyber incidents to be a technical problem. However, they are a business problem that should be dealt with sooner, rather than later. Think of the recent breaches and the telltale signs that signify the breach. 

So, a plan has to be placed to ensure the safety of the organization. As it is not a technical matter, the IR plan has to be designed keeping in mind the alignment of the organization's priorities and its level of acceptable risk.

The information that one would get out of it would be used to gain feedback on the risk assessment process. Moreover, to ensure the better handling of such occurrences, one has to have a plan in place to overcome such an issue. 

Ending note:

Incident response is significant for the maintenance of the business as well. How you act, and when you act will determine how well you are ready to defend the organization.
