How do you adapt incident response scenarios for different contexts?

The best scenarios are built from lessons learned, which can be pulled from within your company, within your field or even in other similar fields.

IR is about planning (which result in context). Context require detailed understanding of all processes (not assumptions), business objectives and threats really relevant to your organization. Once understood, true risk can be assigned/understood. IR plans/playbooks/detection can then be applied effective and efficiently. Spray and prey strategies are expensive and will let you down on the day when you need your IR.

Best ways are to learn the zero day attacks, - How it was detected - what led to the compromise - Steps taken to mitigate In short - lessons learned helps us to create a hypothesis to be pro-active in the field and prepare for the worst.

Align your incident response objetives with your business continuity objectives (RTO, etc) your compliance requirements and your legal requirements (contracts, agreements, etc)

One thing I've found helpful is to laser focus on known areas of opportunity to improve. Reviewing a scenario that was poor, highlighting the areas of opportunity and then running a drill on those specific areas can quickly drive improvement. Always capture lessons learned, even in drill scenarios.

I have already simulated ransomware or phishing attack scenarios, where I evaluated the team's ways of acting from the first contact until the eradication of the threat on the network. Despite being controlled simulations, they were carried out without informing the incident response team at any time.

To ensure high effectiveness during tabletop scenarios it's crucial to plan a detailed scenario and to assign roles to each part. Focus on the team interaction, as most incident responses require a well coordinated team effort. Pre brief the scenario with those who have key roles and encourage everyone wear their "actor" hats to be as realistic as possible. Scripting out the scenario is very helpful and ensures standardization. Debrief after and capture areas for improvement.

Try to participate in purple team activities to get the most out of it as it captures the real dynamics and pressures in terms of risk.

Considering where your threat is most likely to come from, will help you identify the most likely attack vector. Threat intelligence reporting will help highlight any trends in your particular sector which gives a good starting point for creating realistic exercising scenarios.

Suitable framework must be applied to control the IR scenario but with very validated tunning. A good tunning will reduce probability of doing the wrong act for new incident cause every organization differs of others. Clearly, what could be practiced on telecom company is different on what could be practice on another telecom company.

It's helpful to categorize areas of improvement and to create standard drop down answers for feedback. This will improve analysis and ease of reporting, but leave areas for free response as well.

Evaluating must include users and SysAdmin participants to measure the level of user's cybersecurity awareness then you must do awareness improvement accordingly. Indeed, never a suitable time to give awareness improvement more than right after incident response operation.??

It generally involves these key steps: 1. **Assessment**: Understand the incident's nature, scope, and potential impact. 2. **Communication**: Notify relevant stakeholders, both internal and external, while maintaining confidentiality if necessary. 3. **Containment**: Isolate affected systems or areas to prevent further damage or spread. 4. **Eradication**: Identify and remove the root cause of the incident. 5. **Recovery**: Restore affected systems and services to normal operation. 6. **Lessons Learned**: Analyze the incident to improve future response and prevent recurrence. The approach and tools used vary depending on whether it's a cybersecurity incident, a natural disaster, a public relations crisis, or another event.

Have incidents response Playbook/plan tailored to your environment. Use this playbook to internally align on incidents that ocure internally. This should include incident commanders and responders

#??1??8?? ?? Host a Question and Answer session, plus tell a story, and add in some humor: Q: How did the hacker get in? A: Someone left their Windows open. Q: How did hacker get away? A: Used the backdoor and ransomware. Q: Why couldn't the witness identify the hacker? A: Used Spyware and Subnet Mask to hide identity. Q: How did the hacker get caught? A: CSIRT used a Bug, to lure in Scattered Spider, and they got stuck in the Web. A2: The CSIRT used Python to Byte...well, let's just say that a little bird (a.k.a. Parrot) did some squawking, but now they are done talking. Q: What happened to the hacker after getting caught? A: Police made them WannaCry by clearing their cookies. A2: FBI made their Heartbleed by deleting their cache.
