7 Best Practices for Incident Response

Share This

Picture this: An IT manager detects unauthorized login attempts from an unfamiliar IP address on a Friday afternoon. They activate the organization’s incident response plan, but critical elements are missing. There are no protocols for escalating incidents involving potential credential theft, the incident response lead has recently left the company, and misconfigured permissions delay access to critical network logs.

By Monday morning, threat actors have exfiltrated sensitive customer data, and prolonged downtime has resulted in mounting recovery costs and operational disruption.

Now, imagine if the organization had a more robust plan in place: clear communication channels, designated roles, and rapid response protocols. The IT team swiftly escalates and isolates the threat while another team member implements containment measures to prevent it from spreading. These coordinated actions prevent data compromise and stop a minor incident from escalating into a full-blown crisis.

This is the difference between an incident response that follows best practices and one that does not. And with the increasing severity of cyberattacks, organizations cannot afford for their incident response strategies to fall short when it matters most.

Why Is Incident Response Important?

In a landscape rife with sophisticated threats, cyberattacks are inevitable. What makes a difference is how your organization responds to them — making effective incident response more critical than ever. Following best practices can be the difference between containing a threat quickly and allowing it to escalate into a full-scale security incident.

Swift containment and remediation minimize the impact of an attack, reducing downtime and allowing the organization to resume normal operations faster. A prompt response helps prevent extensive financial losses and preserve the organization’s reputation.

Effective incident response also helps protect sensitive information by isolating affected systems to prevent unauthorized access from spreading laterally. It also ensures compliance by facilitating thorough investigations and ensuring teams complete documentation, audit trails, and reporting in line with regulatory requirements.

Additionally, digital forensics investigations provide IT and security teams valuable insights into threats, as well as flagging potential gaps in their security posture. By addressing weaknesses in their defenses, they can strengthen protections to reduce the likelihood of future attacks.

7 Incident Response Best Practices

An uncoordinated incident response can leave gaps in communication and result in prolonged downtime, data exfiltration, and noncompliance with regulatory requirements. To avoid these outcomes and manage threats more effectively, implement the following incident response best practices:

1. Establish an Incident Response Plan

An incident response plan provides a step-by-step guide for managing and responding to security incidents. A clear plan ensures that every employee and stakeholder understands their role during an incident, reducing confusion and delays. As you create an incident response plan, include clearly defined response stages, escalation procedures, and contact information for key team members.

Your plan should also include protocols for reporting the incident. Outline how and when to communicate internally and externally. Additionally, store your plan in multiple spots so it’s accessible during an incident, even if some systems are offline. Documenting incident response procedures in this way not only enables a more coordinated response, but can also streamline post-incident analysis by providing a detailed record of what occurred and how it was handled.

2. Build an Incident Response Team

Effectively managing security incidents requires a dedicated incident response team. The team should include members with diverse expertise, from communication and public relations professionals to legal, IT, and security experts. Many security events also necessitate involvement from third-party cybersecurity and digital forensics specialists.

Make sure your internal team is trained and prepared for various types of incidents. Additionally, designate clear roles for each team member to ensure everyone knows their responsibilities and can deliver a coordinated and efficient response.

3. Leverage SIEM Systems

Security information and event management (SIEM) systems aggregate and analyze security data from across your IT environment. By evaluating data from sources like firewalls and application servers in real time, SIEM systems help you detect incidents early so you can respond before they escalate.

Deeper insights into threats also allow you to initiate more targeted responses. For example, if your SIEM system detects unusual login patterns from a specific IP address, you can isolate the affected systems and block the suspicious IP to prevent further access. For a more comprehensive solution, you can integrate SIEM systems with managed detection and response (MDR) services for monitoring, threat hunting, and rapid response capabilities.

4. Maintain Open Communication

Effective incident response relies on clear communication both within incident response teams themselves and with external stakeholders like customers and vendors. Keeping internal teams informed fosters clarity and enables a more coordinated response. At the same time, transparent external communication allows you to control the narrative, avoid the spread of misinformation, and mitigate reputational damage.

Establish a communication plan as part of your incident response strategy, defining which channels should be used for secure internal communications during an incident. Additionally, establish clear guidelines for external communication, including timeframes for releasing information, key messaging points, and escalation protocols (e.g., when to involve law enforcement).

5. Adhere to Legal Regulations for Compliance

Various regulations govern how organizations report and respond to cyber threats. For example, the Health Insurance Portability and Accountability Act (HIPAA) requires healthcare organizations to notify affected individuals within 60 days of discovering a breach that involves protected health information (PHI).

Failure to comply with relevant regulatory standards during incident response can lead to significant fines and penalties. Your incident response team should be aware of the legal obligations and reporting requirements applicable to your organization. Moreover, involving legal advisors helps ensure compliance and protect your organization from potential legal repercussions.

6. Conduct Post-Incident Reviews

Organize post-incident reviews following security events to assess what went well, identify areas for improvement, and determine how to prevent future incidents. To gain a comprehensive understanding of an incident, include stakeholders from IT, security, legal, and executive leadership. Document the lessons learned and update your incident response plan accordingly to better prepare for similar threats in the future.

Post-incident reviews also help uncover weaknesses in your security posture and offer insights into the effectiveness of your detection, response, and containment strategies — providing a key opportunity to enhance your approach.

7. Continuously Educate and Train Employees

Employees are often the first line of defense against cyber threats, which makes educating them a top priority. Offer routine training on incident response procedures to make sure employees understand their specific roles during an incident and the steps required for timely escalation.

Consider incorporating phishing simulations and tabletop exercises that mimic real-world scenarios to identify gaps in employees’ knowledge and response capabilities. Beyond training specific to incident response, general education about security best practices can help employees stay vigilant and improve their ability to recognize and respond to threats. Hands-on experience and clearly documented protocols significantly reduces the risk of human error during a security incident.
