Business Continuity and Incident Response
Incident response and business continuity are two sides of the same coin. While they share the common objective of ensuring the ongoing operations of the organization during and after an incident, their approaches and focus may differ. Incident response primarily deals with the immediate response to an incident, whereas business continuity plans cover the entire organization and its ability to function during and after a crisis or disaster.
Integrating incident response into business continuity planning enables organizations to effectively respond to and recover from incidents or disruptions that could impact their operations. This involves:
- Identifying incidents
- Containing incidents
- Mitigating incidents
- Resolving incidents in a timely manner
By incorporating incident response into business continuity planning, organizations can ensure minimal impact on business continuity. A robust incident response plan is a critical component of business continuity planning.
Delving into the 7 Phases of Incident Response
Now that we understand the importance of incident response and its role in business continuity let’s delve into the heart of the matter: the 7 phases of incident response. These phases, as outlined by the National Institute of Standards and Technology (NIST), are:
- Preparation
- Identification
- Containment
- Eradication
- Recovery
- Lessons Learned
- Ongoing Improvement
Organizations can create a comprehensive response plan to effectively address cyber threats by following these phases.
Each phase serves a specific purpose, from assigning roles and prioritizing tasks in the Preparation phase to strategizing improvements in the Ongoing Improvement phase. Understanding the objectives and tasks of each phase is vital to construct an efficient and effective incident response plan, which ultimately safeguards your organization from cyber threats.
Phase 1: Preparing for Potential Incidents
In the world of cybersecurity, there is no such thing as being too prepared. The first phase of an incident response plan, preparation, lays the foundation for all subsequent steps. During this phase, organizations must:
- Conduct risk assessments
- Evaluate potential vulnerabilities
- Establish appropriate communication channels
- Ensure that business continuity plans are in place
To achieve this, organizations must define clear communication channels, implement response checklists, and provide staff with quality cybersecurity training. Additionally, having the right tools and infrastructure in place is essential for incident response, as they enable the detection, investigation, and preservation of evidence related to incidents. A well-prepared organization is one that is ready to face potential cybersecurity incidents head-on.
Phase 2: Identifying and Assessing Threats
Implementing clear policies for cybersecurity and incident response, setting up monitoring systems to establish a baseline of normal activity, and training employees to be vigilant in identifying and reporting suspicious activity are some of the recommended practices for identifying cybersecurity incidents. Being proactive in detecting potential security breaches and vulnerabilities can significantly reduce the impact of cybersecurity incidents for organizations.
Phase 3: Containing the Impact
Once an incident has been identified, the next step is to contain its impact and prevent it from spreading to other areas of the organization’s network. The Containment phase focuses on isolating the affected systems and impeding the incident from propagating further.
Swift implementation of containment measures allows organizations to minimize incident-caused damage and limit the potential for further harm. It is crucial, however, not to delete the malware during this phase, as doing so may hinder the response team’s ability to conduct an investigation and restore the files. The containment phase is a delicate balance between limiting damage and preserving evidence for the subsequent phases of the incident response process.
Phase 4: Investigating and Eradicating Threats
With the incident contained, the next step is to investigate the root cause and eradicate any threats from the system. The Eradication phase has one goal: to make sure the threat is no longer present in the organization’s network. Additionally, the affected systems must be returned to their original configuration..
To achieve this, organizations must employ a range of techniques, including:
- Designing and implementing policies and rules regarding data usage
- Implementing network access control
- Utilizing antivirus software consistently
- Monitoring data usage to combat threats
- Enhancing physical security
- Monitoring and instructing users about being mindful with downloads from third-party sites
Thoroughly investigating and eradicating threats enables organizations to take a significant step towards restoring normal operations.
Phase 5: Recovering and Restoring Operations
The Recovery phase of an incident response plan is all about getting back to business as usual. After the threat has been eradicated, organizations must restore the affected systems to their pre-incident state. Files lost during the incident or cyberattack may require a data recovery service to restore them. It is important to contact the relevant service as soon as possible in order to minimize any further losses..
The length and effort required for the restoration and recovery phase will depend on the extent of the damage caused by the incident. Organizations can minimize downtime and ensure a smooth return to normal operations by following a well-documented process and working closely with the incident response team.
Phase 6: Learning from the Incident
After an incident has been successfully managed, it’s essential to take a step back and learn from the experience. The Lessons Learned phase is all about recognizing areas for improvement in the organization’s security posture and incident response plan.
The incident response team should document the lessons learned to build upon their existing knowledge base. This information can then be used to revise the incident response plan and enhance the organization’s overall security posture. Conducting a lessons learned meeting and analyzing the incident allows organizations to uncover valuable insights, improve their overall security posture, and ensure they are better prepared for future incidents.
Phase 7: Ongoing Testing and Evaluation
An effective incident response plan is not a one-and-done endeavor. It requires continuous testing and evaluation to ensure it remains current and effective in the face of ever-evolving cyber threats. Regular testing and evaluation allows organizations to identify and address weaknesses in their incident response plan, ultimately improving their overall security posture.
Strategies and tools for testing incident response plans include tabletop exercises, parallel testing, and tool testing. By committing to ongoing testing and evaluation, organizations can stay one step ahead of cyber threats and ensure their incident response plan remains effective in the face of new risks and incidents.
Incident Response Frameworks: NIST vs. SANS
In the world of incident response, two frameworks stand out as the most highly regarded: NIST and SANS. Both frameworks provide IT teams with a foundation to construct their incident response plans, ultimately helping organizations better manage and mitigate cyber threats.
The primary distinction between the NIST and SANS frameworks lies in their approach to containment, eradication, and recovery. NIST believes that these processes are interrelated, indicating that containment of threats should not be delayed until eradication is completed. While there is no definitive answer as to which framework is more suitable, it is essential for organizations to carefully evaluate their specific needs and requirements and choose the framework that best aligns with their objectives and strategies.
Building and Implementing an Effective Incident Response Plan
Creating and implementing an effective incident response plan is not a simple task.
