In recent years, cybersecurity attacks have risen dramatically, making Incident response a critical aspect of any business strategy. This is never more accurate than when considering the cost, both financial and reputational, associated with data breaches. Today, we are going to decode the blueprint of an Incident response procedure in the realm of cybersecurity. We will look at a detailed Incident response procedure example where we digitize the entirety of a generic response to clarify what each step entails. This blog post aims to give you an in-depth understanding and appreciation for what cybersecurity professionals do to keep your information safe.

The Incident response procedure proceeds in various stages. Various organizations name these stages differently, and some include additional stages. However, for this Incident response procedure example, we are going to use the six standard stages under the National Institute of Standards and Technology (NIST).

Preparation

The first phase in every cybersecurity Incident response procedure is the preparation phase. It is where holistically you identify your most valuable assets, characterized by information that if leaked would cause significant harm to the organization. For example, customer information, patent information, or unreleased strategic data.

Preparation also involves creating an Incident response team made up of various individuals, each with a specific role to play in case of an incident. Creating an Incident response Plan (IRP) detailing what should be done when an incident occurs is also part of this stage. Virtual drills can be enacted to test the effectiveness of the plan.

Identification

Once preparation is well set, the next stage is identification. This step involves detecting and characterising what could represent an incident. Through using various tools and techniques such as firewalls, antivirus software, and intrusion detection systems, the team can identify potential threats.

Containment

The next stage is containment. At this point, control measures are put in place to prevent further damage. This is done in two phases - short term and long term containment. Short term containment may involve disconnecting affected systems from the network to prevent the spread of the threat. Long term containment may involve strategies like reconfiguring firewalls to block the attack.

Eradication

Having contained the situation, the next focus is on eradication. Eradication involves making sure that the threat has been completely removed from the system. Techniques for doing this include system restoration, software upgrading, or even complete reinstallation of the system in question.

Recovery

Once the threat has been successfully eliminated from the system, recovery steps can commence. Now the Incident response Team must restore and validate the systems for business resumption, conducting thorough testing to ensure the system is fully operational and secure.

Lessons Learned

The final stage in the Incident response procedure example is lessons learned. This phase aims to learn from the incident. It involves completing the post-incident documentation and analysing the incident and the response for lessons that may improve future response efforts.

In conclusion, an Incident response procedure in cybersecurity should be a vital part of the strategy for any company dealing with sensitive data. Being prepared and knowing how to respond can make a note-worthy difference in the outcome of any data breach. If firms invest time and resources into their cybersecurity Incident response procedure, they will protect their assets better and bounce back from incidents much faster. This blueprint of an Incident response procedure example gives a basic but crucial look into what must be done, from preparation to lessons learned. Understanding each of these components will better prepare you for any cybersecurity threats that may come your way.
