Today, cyber threats are becoming increasingly sophisticated. While everyone is aware of the danger, only a handful know how to handle these attacks. The growing threat landscape has made it imperative for organisations to be able to respond quickly to cyber incidents and take preventative measures against future risks. How can organisations respond to a cyber incident? There are three major categories that are used to prepare any organisation for incident response: people, procedures, and technologies. In cybersecurity, the technological component is frequently given more attention. While technology is undoubtedly important, effective incident response readiness and planning cannot be complete without emphasising the individuals and due process. This blog post will walk you through what incident response is, its importance, preparation concerns, and the seven steps of creating your own incident response plan.

What Is an Incident Response Plan for IT?

An incident response plan for IT is an actionable procedure needed to prevent, detect, and address any cyberattack. The incident response plan outlines what steps to take and what not to do in case of a security breach. Typically, a cybersecurity incident response plan contains the following information:

• Steps for preparation and prevention to thwart cyberattacks
• Steps for identification and evaluation
• Guides to recovery, elimination, and containment in case of an attack
• What crucial steps need to be taken following the incident

Apart from this, an incident plan establishes clear communication channels and individual and team roles and responsibilities. A well-structured incident response plan can make all the difference for an organisation, as it assists in containing an attack, minimising damage, responding to regulatory monitoring, and maintaining employee and customer trust. Having a good incident response means investing in controls, enhancing security performance, and taking other necessary actions to strengthen your overall security posture. If an organisation invests in such a plan, it is sure to reap benefits in terms of overall risk management.

Why Do You Need An Incident Response Plan?

Simply put, an incident response plan is an investment in your current and future security. It helps your organisation clearly identify current assets that need protection and outline how to proceed in case of an immediate security breach. In terms of future protection, an IRP provides information and assists in avoiding similar incidents in the future. One of the core components of information security management is promptly reducing an information security incident’s adverse effects. While discussing the need for an incident response plan, one must also look into what is at risk without one. Without a decent incident response plan, you risk the following:

• Tainting your organisation’s mission and goals, including losing credibility with users and other stakeholders.
• Losing company revenue and important data.
• Possibly facing regulatory penalties.

Incident response planning aims to identify stakeholders, streamline digital forensics, enhance recovery times, minimise the length and damage of security incidents, lower bad press, and retain customers. With an effective incident response procedure, your company can reduce losses, patch vulnerabilities, recover compromised systems and processes, and seal the attack vectors that were used. For example, malware infections are minor cybersecurity events that can grow into more significant issues that ultimately result in data loss, breaches, and disruptions to business operations. However, this would not happen if your company had an effective incident plan in place.

How To Build An Incident Response Plan?

To create an effective incident response plan that can ultimately protect your company from cyber attacks, it is essential to comprehend the goals and responsibilities of each phase. Every stage has a distinct function; for example, the preparation phase assigns roles and prioritises work, while the ongoing improvement phase strategises improvements. What, when, and how to do certain things in the event of an incident are all covered in general terms by an incident response plan. If you want to create an effective IRP, you can do so by adhering to the stages mentioned below. When done correctly, your organisation will have a thorough response strategy to deal with cyber threats.

-Understanding Your Requirements

Do a thorough risk assessment before creating an incident response plan to identify potential threats and weak points in your infrastructure. In this step, key assets and services must be prioritised, and recovery time and recovery point objectives must be specified based on business needs. This is the crucial step that will dictate what follows next in creating a good IRP.

-Defining Your Goals

Businesses must define clear goals to successfully manage an internal incident response team. Once they have identified gaps in security and other weaknesses, they are part of prioritising them. Clearly mention what you want out of the incident response plan. To improve processes and guarantee preparedness for actual incidents, it is imperative that you regularly test and validate your plan using exercises, simulations, and drills.

-Creating A Response Framework

The response process from beginning to end and the actions that need to be taken at each phase must be described in detail in a document. This creates a framework that is iterative and prescriptive for managing the stages of an event, such as pre-, during-, and post-incident. This response framework must be updated from time to time depending on the need of your organisation.

-Assigning An Incident Response Team

IR plans are intended to be carried out by a specific reaction team. Since each member of your response team is crucial to the detection, mitigation, and recovery from a future incident, it is imperative that they recognise and accept responsibility for their respective roles and obligations. Make sure that your plan explicitly delineates the individual accountable for specific facets of incident management. During a crisis, confusion may lead to the abandonment of crucial tasks, which would seriously impair team performance.

-Regular Revisions And Updating

Strong cybersecurity postures require auditing and logging because they provide information about system activity and security occurrences. The benefits of threat detection, incident response, and compliance can be reaped only if they are updated. At the very least, incident response plans ought to be reviewed and approved once a year. They should also be updated every time the company’s commercial, regulatory, or compliance structure or its IT infrastructure changes.

7 Steps Of Incident Response in Cybersecurity

An incident response plan is a carefully drafted multi-stage guideline on the dos and don’ts in case of a cyber breach. It is held in place by the IR team and their effectiveness in following the instructions. Every stage has a distinct function; for example, the preparation phase assigns roles and prioritises work, while the ongoing improvement phase strategises improvements. To create an effective incident response plan that can ultimately protect your company from cyber attacks, it is essential to comprehend the goals and responsibilities of each phase. Let’s get right to the point: the seven stages of an incident response plane.

1. Preparation

There is no such thing as being overly prepared in the realm of cybersecurity. The incident response plan’s preparation phase is the beginning of it all; it sets the stage for the other phases that follow. In this stage, the focus is on making risk evaluations, assessing any possible weaknesses, and coming up with suitable communication routes in case of a crisis. The preparation phase also takes on the task of making sure that there is a plan for maintaining company continuity amidst the chaos. Establishing response checklists, defining clear communication routes, and giving top-notch cybersecurity training to employees are all necessary for achieving this. Furthermore, incident response depends on having the proper infrastructure and technologies in place because these facilitate incident detection, investigation, and evidence retention. The better your preparation, the better your chances of beating a possible cyber-attack.

2. Detection and Analysis

Businesses need to truly understand the cybersecurity dangers they face today. They need to keep track of every piece of information, system hardware, software, staff, and data they have. They help locate the signs that an occurrence is either likely to happen or has already happened, and they are known as precursors and indicators. Once an indicator or precursor has been found, the IR team decides if it is a true positive or a component of an attack. Security teams decide whether to activate an incident response plan during the identification phase. The IR team will need to start recording all incident-related details and keep track of all measures done if the signal turns out to be legitimate. The most critical decision point in the incident response process is incident prioritisation. The incident response team cannot just prioritise them on a first-come, first-serve basis.

3. Containment

After discovering an issue, the next step is to control its effects and stop it from propagating to other parts of your company’s network. The goal of the containment phase is to isolate the compromised systems and prevent the incident from spreading. As you go through this phase, you should also collect and store as much evidence of the attack as possible for internal and external use. Additionally, you may also want to try to figure out who is attacking, though it could take a while and, in some cases, be impossible. As fast as possible, you should always try to contain the occurrence first before trying anything else.

4. Eradication

After containing the incident, the next course of action is to look into the underlying cause and remove any security risks from the system. Ensuring that the danger has left your organisation’s network is the sole objective of the eradication phase. Depending on the kind of occurrence you’re dealing with, there are many procedures involved in eradication. In essence, you’ll be getting rid of whatever you need to get rid of in order to stop the threat. Once that is achieved, you can work on getting the impacted systems back in their original configuration. In order to accomplish this, your company will need to use a variety of strategies, ranging from creating and enforcing guidelines and procedures for the use of data, utilising network access controls and antivirus software, to increasing the level of physical security. By thoroughly examining and eliminating hazards, you can make a big step towards getting back to business as usual.

5. Recovery

Restoring normalcy is the primary goal of an incident response plan’s recovery phase. Your organisation must return the impacted systems to their pre-incident state once the danger has been neutralised. A data recovery service can be necessary to recover files that were lost during the cyberattack. In order to reduce further losses, it is critical to get in touch with the appropriate provider as soon as possible. The degree of damage produced by the occurrence will determine how long and how much work the repair and recovery phase takes. By adhering to a well-documented procedure and following necessary steps for rapid recovery with the incident response team, your organisations can reduce downtime and guarantee a seamless return to regular operations.

6. Post-Incident Activity

After the crisis has been stopped, security fixes have been implemented, and your business is back on track, your organisation should take some time to debrief from the occurrence. Think back on what transpired and discuss how to recognise and prevent similar events in the future. Evaluate the extent of the attack and harm caused. Understanding the seriousness of an occurrence and the amount of damage it produces can be challenging. Generally speaking, you should investigate what caused the situation. When an external attacker or hostile insider succeeds, treat the problem as more severe and take appropriate action. Review your plan and discuss with your team any changes that may have been made to increase its effectiveness.

7. Further Testing and Updating

Creating a successful incident response plan is a continuous process. To ensure it stays up-to-date and functional in the face of constantly changing cyber threats, it needs to be tested, evaluated and updated regularly. Your organisation can improve its overall security posture by identifying and addressing weaknesses in its incident response plan through regular testing and evaluation, especially after a significant incident. The knowledge generated from dealing with a cyber incident can be helpful in the event of future occurrences and in revising rules and procedures. Tabletop exercises, parallel testing, and tool testing are some other methods and resources that can be employed to test incident response plans. By committing to regular testing and review, you can guarantee that your incident response strategy stays successful in the face of new risks and incidents. This will help you stay one step ahead of cyber threats.

Conclusion

A proactive approach to incident response is necessary in light of the current cybersecurity threat landscape. Robust logging procedures and efficient coordination lessen the effects of incidents and guarantee operational resilience. Being ready is essential in a world where cyber-attacks are unavoidable. Your business must have a strong and efficient incident response plan in place to protect its digital assets and maintain operations in the event of a cyberattack. You can significantly improve your security posture and resilience against cyberattacks by adopting best practices for developing and implementing a customised incident response plan. Recall that proactive testing, assessment, and evaluation are just as crucial to successful incident response as having a plan in place.
