In order to mitigate any potential risk from incidents, companies need to have an incident response plan that is constantly updated based on industry knowledge. Incident response is the process of identifying and mitigating computer or network security problems. This includes detecting, responding to, and recovering from incidents.
What does an incident response team do?
A team should consist of members from diverse parts of the business. Without members from these fields, an incident response efforts is likely to be ineffective and costly. The team not only helps to execute the IRP but also aids with ongoing oversight and maintenance, including the day-to-day administration of technical controls. Each team member should have clearly defined duties and goals. These are actions that not only take place during an incident, but also before and after an incident occurs. The incident response team may involve members of the organization’s overall security committee.
Who is responsible for incident response?
A company should create an incident response team to properly respond to security threats. They are responsible for analyzing events and responding accordingly, so it’s a necessity for any business.:
An incident response manager, usually the director of IT, who oversees and prioritizes actions during the detection, analysis and containment of an incident. The incident response manager also conveys the special requirements of high-severity incidents to the rest of the organization.
Security analysts who support the manager and work directly with the affected network to research the time, location and details of an incident. Triage analysts perform a filtering system that eliminating false positives and keeping an eye out for potential intrusions. The forensic analysts recover key artifacts from the compromised machine as well as maintain the integrity of evidence – leading to more solid forensics.
What threat intelligence analysts do is help provide context for an incident that has or will occur. They scour the internet and identify information that may have been reported externally. They work alongside security teams to uncover details of an attack in advance to mitigate potential impact. Threat researchers combine this data with an organization’s records of previous incidents to build and maintain a database of internal intelligence. If this level of expertise does not exist in-house, it can be outsourced.
Management support is key to securing the necessary resources, funding, staff and time commitment for incident response planning and execution. It is becoming more common for incident response teams to have a CIO or other senior executive as a leader and evangelist. They help the team understand the importance of what they do & give them support. An outside consultant who specializes in incident response can be a good addition to the team when needed.
The incident response team may also include a human resources representative, especially if the investigation reveals that an employee is involved with an incident. Audit specialists are responsible for developing vulnerability assessments & best practices across the organization. They also offer an essential perspective on security to help reduce risk of data breaches.
The organization’s general counsel can ensure that the collected evidence maintains its forensic value in case the organization decides to take legal action. Attorneys also provide advice about liability issues when an incident affects vendors, customers and/or the general public. Finally, a public relations specialist is essential to keep in touch with team leaders and to ensure accurate and consistent information is disseminated to the media, customers, stockholders and other interested parties.
Incident response plan management
Incident response is not unlike any other aspect of information security. It requires thoughtful planning, ongoing oversight and clear metrics so that efforts can be properly measured. Ongoing management initiatives include setting and overseeing incident response goals, periodically testing the IRP to ensure its effectiveness and training all the necessary parties on applicable incident response procedures. Specific metrics used to measure the effectiveness of incident response initiatives might include:
Number of incidents detected.
Number of incidents missed.
Number of incidents requiring action.
Number of repeat incidents.
The remediation timeframe.
Number of incidents that led to breaches.
Additionally, incident response goals might include areas involving:
The routine incident response plan is currently under review. Updates will be posted as soon as they are ready..
The planning and execution of incident response test scenarios.
There are integration issues when different security initiatives such as technical detection systems, security awareness training and penetration testing are put together.
The reporting of security events to executive leadership or outside parties.
The procurement of additional technologies that can provide enhanced network visibility and control.
Incident response plans vs. business continuity plans
Incident response is a business strategy designed to maintain normal operations and minimize the impact of events that aren’t expected. It could be considered apart of the business continuity process. Given what is at stake and the different variables involved, such as people, technologies and business processes, incident response should have the highest levels of visibility within the organization. An IRP is dedicated to incidents and breaches impacting networks and computers, applications and databases and related information assets. Therefore, most organizations are best served by keeping the incident response plan in a standalone document — separate from, yet referenced in, the business continuity plan. The most important thing is to ensure the incident response plan is easily accessible by all team members when it is needed.
Tools for incident response
There are numerous tools and methodologies that can be used to assist with incident response and are typically categorized by prevention, detection or response functionalities. Certain organizations use OODA loops to help them during incident response. OODA loops is a strategy that emphasizes a company’s ability to observe changes, orient itself to estimate the situation, decide prior to the next action and finally taking it. AI tools can help with all of these aspects by giving some relevant insight.
For example, an organization can gain the necessary visibility into an incident with packet analysis, system resource monitoring and file integrity examination technologies. Insight can be gained into threats by using real-time threat indicators and threat intelligence services. Even further, there are tools that can provide forensics details such as source location, incident technical information and event replays. There are also tools that allow an organization to act against a threat by stopping it from spreading or minimizing the impact it has on the computing environment.
While incident response is a process, technology can be used to automate and streamline specific incident response functions to help minimize detection times and system errors. Incident response technology in the cyber security field focuses on providing products in the following categories:
employee awareness and training;
endpoint security management;
firewall, intrusion prevention, and DoS mitigation
net flow and traffic analysis;
Security incident and event management, or SIEM, is unique because it collects and analyzes data on security threats as they occur.
Incident response tools provide organizations with both visibility and control. They also provide professionals with the necessary information they need to know to handle the anomalous behavior. Finally, incident response tools help with direct response efforts — allowing organizations to minimize the risks involved.
Most incident response products are commercial and require proper budgeting of capital and operating expenditures. Alternatively, there are numerous open source software offerings that could be tailored to meet a specific organization’s requirements. When choosing the open source approach, it is important to weigh how much effort will be involved, how efficiently it will be able to scale and how effective it will be long term.
Once incident response tools are put into place, it is important to ensure that there is enough staff and expertise to keep it maintained and updated. Having the necessary resources is critical for the initial design and implementation of the technology, as well as ongoing administration and troubleshooting.
Finally, executives must remember that incident response tools cannot comprise the entire incident response program. While tools and automation may play a large role, they should still only be one component of the overall incident response requirements
