Nowadays, organizations need to be prepared for the possibility of a cyberattack. This involves not only measures designed to stop threats but also plans for responding to any potential security incidents. Building incident response playbooks is a vital part of any cybersecurity strategy, as prevention tactics can never be fully effective.
When putting together incident response playbooks, there are a number of steps that organizations must take in order to ensure their plans are comprehensive, effective, and reliable. Using the right tools, practices, and technologies, organizations can build incident response playbooks to meet any threat and reduce the impact of attacks and other security incidents.
Challenges of Incident Response
The many jobs associated with security operations can be daunting for human teams to handle alone. As such, measures such as automated incident response are important to cover a broad attack surface and protect against a wide range of threats. As new and evolving methods and technologies like Software-as-a-Service apps, public cloud usage, and remote and hybrid working environments continue to grow in popularity, “IT infrastructure is sprawling.”
Incident response is one of the most time-consuming parts of cybersecurity, especially if it’s left entirely to human teams. The process of detecting, investigating, containing, and remediating attacks and other cybersecurity incidents involves many different operations and tools that must connect and interact.
Automation is one major way that organizations can ensure their incident response plans are effective and efficient. API integration is also a significant factor in incident response, as the smooth and secure integration of APIs can greatly speed the process of remediating an incident. Measures that automate and simplify large parts of a complex incident response plan can make the difference between a quickly remediated threat and a catastrophic security incident.
Building Effective Incident Response Playbooks
Developing incident response playbooks provides a standard procedure for handling any potential threats, eliminating many of the unknowns in the wake of a cybersecurity attack. There is a diverse array of incidents that organizations may need to respond to, but most attacks fall into a few set activity patterns and require similar plans. Ensuring smooth integration and communication throughout incident response is difficult, but with the right tools, practices, and policies, the process can be simplified while maintaining its efficacy.
An effective incident response playbook should include information such as:
- What constitutes an “incident”—specific definitions of what activities or triggers make a security incident to avoid confusion or delay when identifying threats.
- Roles and responsibilities—clear designation of roles and responsibilities, ensuring that incident response team members understand their functions and duties in the process of incident management and response.
- Workflow—delineation of a practical, logical, and consistent workflow for teams to follow when carrying out incident investigation and remediation.
- Checklists—lists of tasks that must be done in order to carry out the steps of incident response, enabling quick verification of which jobs have been done.
- Full incident response process—detailed instructions from beginning to end, providing teams with guidance for each step of incident response, helping them to carry out the incident management stages required for each specific threat.
- Governance and regulation—any information related to compliance with laws or regulations that must be a factor in incident management.
- Specific policies—any activities or practices that must be carried out in addition to the basic steps of investigation and remediation, such as those required by local laws or industry-specific standards.
Tips and Best Practices for Building Incident Response Playbooks
The more effective your incident response playbook is, the quicker your organization can respond to and remediate cybersecurity incidents. In order to build effective incident response playbooks, organizations should follow a few best practices, including:
- Create playbooks that cover the most common types of attacks and security incidents: phishing, ransomware, DDoS attacks, insider threats, compromised accounts or devices, and more.
- Prioritize clarity and thoroughness to build a playbook that will be as helpful as possible for incident management teams to work with.
- Use automation where relevant to alleviate some of the burden of incident response from human security teams, simplifying and streamlining time-consuming processes like detecting potential incidents, analyzing threat intelligence, gathering and analyzing logs and metrics, and sending and resolving alerts.
- Ensure smooth API integration to ease communications and interactions between different tools during the process of incident management, enabling quicker response and remediation.
With this guidance, your organization can develop effective incident response playbooks to manage a wide array of security incidents that may occur. Focusing on the importance of simple, clear instructions, teams can build playbooks to respond to many threats that can put organizations at risk. Incident response playbooks provide consistent and reliable guidelines for security teams to follow when investigating and remediating security incidents, empowering organizations to optimize their incident management operations.
