What is incident explain procedure for responding to incidents?
Incident response (IR) is a set of information security policies and procedures that you can use to identify, contain, and eliminate cyberattacks. The goal of incident response is to enable an organization to quickly detect and halt attacks, minimizing damage and preventing future attacks of the same type.
Advantages of Post-incident Review
Low and slow attacks easily bypass traditional security defenses by incremental actions that on their own are too small to detect, but put together can devastate an organization.
OPERATION SOFT CELL
In 2018, the Cybereason Nocturnus team identified an advanced, persistent attack targeting global telecommunications providers carried out by a threat actor using tools and techniques commonly associated with the Chinese-affiliated threat actor APT10.
EXISTING SECURITY TOOLS ARE NOT ENOUGH
Network forensics is useful, but is limited to 2-4 weeks worth of raw data, with a few additional weeks for metadata. Further, capturing and storing packet capture is expensive.
How often should a post incident review be held?
Adopt a defined cadence; for example, CSG holds a global review two times per week for an hour. Be sure to invite teams and stakeholders from across the entire organization in order to increase awareness about the incidents discussed, to build an open culture of incident management, and to build resilience across the organization. Extend the invitation to your customer-representative teams, including Customer Liaisons, Platform Engineer teams, and engineering teams across multiple product portfolios.

Why do we take notes during a PIR?
Taking notes during the PIR ensures that information persists beyond the meeting. These notes should be published somewhere like a wiki and made accessible throughout the organization. Filling out a form typically drives behaviors that focus on filling out the form instead of having a good discussion. We recommend letting the conversation flow to ensure you can answer the questions listed above but avoiding a form. If a form must be filled out, fill it out later based on your notes.
What is the purpose of a review meeting?

Hold a Global Incident Review if a major incident has occurred.
Who should attend a PIR?
Attendees of the local post-incident review (PIR) should include all engineering team members engaged on the call and full teams of those closest to the problem.
1. Decide which incidents need review
Incidents in your organization should have clear and measurable severity levels. These severity levels can be used to trigger the post-incident review process. For example, any incident Sev-1 or higher triggers a post-incident review, while post-incident reviews can be optional for less severe incidents.
2. Draft your review within two days of the incident
It’s important to take a break and get some rest after an incident. But don’t delay writing the post-incident review. Wait too long and important details might be lost or forgotten. Ideally, it’s drafted immediately after a meeting with the incident team, within 24-48 hours (and not more than five business days) of the incident resolving.
3. Assign roles and owners
Have a meeting to hash out the details that will be recorded into the review. It’s a good idea to delegate drafting the review to a specific person, ideally someone familiar with the incident who has the required level of technical and organizational knowledge to understand the causes and mitigations.
4. Work from a template
A template can keep you from leaving out key details. And it’s a great way to build consistency throughout your postmortem. Check out this example post-incident review template to get started.
5. Include a timeline
A timeline is a very helpful aid in incident documentation. Often it’s the first place your readers’ eyes jump to when trying to quickly size up what happened. You can use the activity feed of an incident to help you see what happened when. Try to be as clear and specific as possible. For example, “11:14 am Pacific Standard Time,” not “around 11.”
6. Add as many details as possible
Leaving out details is a quick path to writing post-incident reviews that are unhelpful and unclear. Add as many details as possible about what happened and what was done during the incident.
7. Capture incident metrics
When you capture metrics in your post-incident reviews you apply hard data to the issues and their impact. Having these data points helps you determine if your team is headed in the right direction; reducing the number of incidents, their severity, and downtime.
How to conduct a post incident review?
The post-incident review process begins with determining who will conduct the PIR. An effective review depends heavily on the objectivity of the review team. For that reason, you should select a team of individuals that are not part of your local organization, or, if from your site, were not involved with the response to our management of the incident. (The responders and managers will have an opportunity to provide their input later in the process.) The team should provide expertise in management, human factors, communications, planning, and training. The team should include specialists that are technical experts in particular areas of concern for the specific incident. Specialty areas may include disaster response and management, fire, hazardous materials, environmental impacts and regulations or hostage situations. Several members of the team should also have strong interpersonal skills to facilitate capturing information through discussions and interviews with incident managers and responders. The team should have access to an advisory group of managers and senior leadership from within the organization that experienced the incident. These advisors help guide the activities of the team toward the philosophy of the organization. Their direct experience also assists with the assessment of how management responded to the incident and what long term effects have occurred as a result of their actions or the incident itself.
What is a review question?
These questions will, among other things, seek to explore each important aspect of the incident. They should be applied to each available source of information on the incident; plans, procedures, records , and participants (through interviews). While the questions are being developed, another part of the team will begin a records review to build a list of incident participants.
What is a PIR?
Post- incident review (PIR) is an evaluation of incident response used to identify and correct weaknesses, as well as determine strengths and promulgate them. PIRs are normally used to support program revision. Despite its importance, PIR is one of the most neglected components of disaster recovery planning.
What should be modified if the report revealed weaknesses or gaps in the organization?
If the report revealed weaknesses or gaps in the organization, the disaster response and/or crisis management structure should be modified;
Why do we use checklists in PIR?
These portions of the team should develop checklists from the review questions used by the interviewers. Using a checklist with a comprehensive description of each area of consideration during plans analysis and record reviews helps keep these parts of the PIR objective and complete.
When should disaster response and/or crisis management plans be modified?
In areas where participants diverged from their existing plans and response or management operations went especially well, the disaster response and/or crisis management plans should be modified to reflect the reality of success.
Should disaster recovery and crisis management programs be revised?
Based on the PIR, disaster recovery and crisis management programs should be revised to improve future performance. This could lead to revisions in several areas:
Who should moderate an incident critique?
Ideally, the incident critique should be moderated by personnel who are: Experienced and knowledgeable in emergency response. Not directly involved in the actual incident. The following subjects and discussion points should be used as guidelines for conducting a post incident critique with employees and responders: 1. Detection.
How can our emergency response process be improved?
The question “How can our emergency response process be improved?” should be asked for each subject under the post-incident critique. Through a detailed investigation and post incident critique, procedures, training and plan revisions can be identified and implemented for a more effective emergency response program.
What to publish from an incident postmortem?
You may also decide to publish takeaways from your incident postmortem with customers or the rest of your organization. This can go a long way in rebuilding confidence in people who may not have been closely involved as the incident was happening. Other teams in your organization, especially leadership, may need to see the details of the problem and what steps were taken to resolve it to head off any second-guessing of your team in the future.
How to work through what happened during an incident?
The best way to work through what happened during an incident and capture any lessons learned is by conducting an incident postmortem, also known as a post-incident review. An incident postmortem brings people together to discuss the details of an incident: why it happened, its impact, what actions were taken to mitigate it and resolve it, ...
Why do teams use blameless postmortem?
This approach is key to making sure your teams openly share information and get to the root cause of an incident. If anyone fears rebuke they may hold back information or try to redirect blame. When this happens, people lose trust in each other. And the organization loses the opportunity to build resiliency in its teams and systems. Many teams, including here at Atlassian and at Google, have adopted the tenants of the blameless postmortem in order to avoid those pitfalls.
Why is a postmortem important?
A postmortem is an important step in the lifecycle of an always-on service. The findings from your postmortem should feed right back into your planning process. This ensures that the critical remediation work identified in the postmortem finds a place in upcoming work and is balanced against other upcoming work and priorities.
Why do you use metrics in incident postmortem?
When you capture metrics in your incident postmortem you apply hard data to the issues and their impact. Having these data points helps you determine if your team is headed in the right direction and reducing the number of incidents, their severity, and downtime. With consistent metrics being measured, you can take a step back and look at incident trends over time.
What to focus on in a postmortem meeting?
Instead, focus on actions, results, and impact.
What is incident learning?
Incidents are also a learning opportunity. A chance to uncover vulnerabilities in your system . An opportunity to mitigate repeat incidents and decrease time to resolution. A time to bring your teams together and plan for how they can be even better next time. The best way to work through what happened during an incident ...
