A company’s cybersecurity plan must include incident response as a core element. There will always be intrusions; what matters is how they are discovered and handled.
Let’s examine the significance of incident response and best practises to keep in mind as businesses create and enhance their incident response strategies.
What Does Incident Response Mean and Why Is It Significant?
Preventative measures are the first line of protection against cyber assault. To ward against malicious actors, security teams employ encryption, login credentials, anti-malware, firewalls, and other techniques. Even the best types of defence, however, can fail since no defence is impenetrable. Here comes the role of incident response.
The term “incident response” describes a group of proactive steps done during an incident to stop the attack and lessen the damage. It necessitates having access to immediate notifications or warnings that indicate an active threat, then a pre-planned series of actions to reduce the consequences of the breach, safeguard data, and resecure the network.
Every second matters while a breach is currently taking place, thus incident response strategies must be created far before a threat. Attacks can cost thousands of pounds and compromise crucial data, wreaking more and more damage with each passing second. The impact is reduced the sooner it is stopped.
Who Bears the Responsibility for Incident Response?
A pre-established incident response team is normally responsible for incident response. Roles are assigned within the team based on necessity. Cybersecurity analysts, IT administrators, threat researchers, risk mitigation advisers, legal counsel, and even external or outside security professionals could be on this team.
The incident response team is in charge of creating a thorough incident response plan in addition to doing preventative actions including fixing system flaws and enforcing security guidelines. This strategy ought to specify what each person will do in the case of an assault. It’s crucial to allocate jobs based on accessibility so that the appropriate individuals can respond regardless of when an assault happens.
Optimal Approaches for Incident Response
Best practises for an incident response should be followed by organisations to make sure they are ready to act when necessary. The guidelines that follow ought to be implemented at the team (people), strategic (framework), and tactical (plans/playbooks) levels.
1. Develop an Incident Response Plan
The measures that the incident response team should take in the case of an occurrence should be outlined in an incident response plan. The strategy aids teams in reducing reaction and recovery times to efficiently and swiftly resume business operations.
2. Implement an Incident Response Framework
Plans for responding to incidents are frequently based on incident response frameworks, which describe the ideal organisational structure for responding to incidents. These frameworks describe the response operations and the grouping or segmentation of the operations. Examine such frameworks while creating an incident response plan to identify the components that are most appropriate for your firm.
3. Adhere to the Six Stages of Incident Response
The fundamental steps for dealing with incidents are outlined in incident response frameworks. The following are the six phases that incident response frameworks frequently employ:
- Preparation. The development and ongoing evaluation of policies and playbooks, risk analyses, the selection of an incident response team, and other duties are all part of this phase’s preparation for an incident.
- Detection. In this step, an incident is identified, evidence is gathered, and the seriousness of the incident is assessed.
- Containment. Tasks to reduce the impact of an incident are part of this phase.
- Eradication. This entails addressing the incident’s underlying cause.
- Restoration. This stage involves resuming normal operations for the affected systems and equipment.
- Post-incident assessment. This includes recording the incident in order to understand how it occurred and use the lessons learned going forward.
4. Formulate Incident Response Playbooks
Organisations should have a collection of incident response playbooks, or step-by-step instructions, on how to handle frequent occurrences like malware infections, phishing and ransomware assaults, network intrusions, and ransomware attacks. Playbooks aid in ensuring that problems are handled quickly and uniformly throughout a business.
5. Establish an Incident Response Team
For incident response strategies and playbooks to be properly implemented, an incident response team is necessary. Depending on the demands of each company, an incident response team’s size, composition, and name may vary, but its objectives always remain the same. Consider which individuals to include on an incident response team, both internal and external, as well as their roles and duties. Supporting team members are required, including communication representatives, external stakeholders, and third parties, such as suppliers and consultants. A core technical team should consist of an incident response manager, security analysts, and incident responders.
6. Maintain Open Communication Channels
An incident response communication plan aids teams in exchanging information about security occurrences and giving updates on the status of the incident response. Depending on the issue, both internal and external communications may be required.
7. Provide Training for Incident Response Staff
The incident response team’s members must get training on incident response procedures and their individual duties. Run incident response simulated exercises to make sure team members are ready for a genuine occurrence and conduct regular training to make sure everyone on the team knows how to react.
8. Consistently Assess Procedures
In reaction to shifts in IT infrastructure, company operations, personnel, and the continually evolving threat landscape, incident response procedures must be continuously assessed, reviewed, and updated. Plans that are out of date cause confusion and compromise incident response protocols.
9. Search for intrusions
Stop waiting for a mishap to occur. To proactively find signs of compromise, use threat intelligence and threat hunting. Use detection technologies that notify incident response teams of any questionable activity.
10. Perform Post-Incident Reporting and Extract Valuable Insights
The incident response team should provide a report on what happened, how it was handled, and any lessons learned, such as how to better respond to a similar event in the future, and if an incident could have been prevented, mitigated, or resolved. Adapt strategies and playbooks as necessary.
11. Select the Appropriate tools
To identify, evaluate, and manage threats as well as to provide reports, incident response teams require the appropriate incident response technologies. The following are examples of common incident response tools:
- Tools for vulnerability management.
- SIEM apparatus.
- Detection and response at the endpoint.
- Orchestration, automation, and reaction in security.
- Tools for forensic analysis.
12. Explore Automation Possibilities
Understaffed or overworked incident response teams can benefit from automation. Security analysts may sift through a flood of data to locate and analyse potential problems with the use of automated incident response solutions that use AI and machine learning. They can also prioritise mundane activities and low-level occurrences, freeing analysts to concentrate on more urgent problems.
13. Outsource When Necessary
Companies that are unable to manage crisis response internally may be better served by outsourcing part or all incident response duties. For businesses without the staff or resources to handle it themselves, managed security service providers can handle threat detection and response, help with communications and PR management, and handle crisis management.
