What do you do if your information security incident response plan fails to meet key success factors?
When your information security incident response plan (IRP) doesn't meet its key success factors, it can feel like a significant setback. However, this is a critical moment for learning and improvement. An IRP is a predetermined set of instructions or procedures to detect, respond to, and limit the consequences of a malicious cyber attacks, such as data breaches or network intrusions. The key to moving forward is to analyze the failure points, adapt your plan, and ensure that your team is better prepared for future incidents. Let's delve into the steps you should take if you find yourself in this situation.

After an incident, promptly assess where and why your IRP fell short. This involves a thorough review of the incident timeline, the effectiveness of the response actions taken, and the communication flow among team members. By identifying the specific stages where the plan didn't hold up, you can pinpoint critical areas for improvement. It's essential to approach this assessment without placing blame and instead focus on constructive feedback that will strengthen your security posture.

Between well-structured incident response plans and the reality of events lies a chasm called "life happening." Do your part by testing your plan periodically through simulations and hiring specialized cybersecurity firms to have unbiased professionals test your environment. However, have a plan for when the plan fails. Include aspects such as managing your stress, minimizing the impact on the business, knowing your infrastructure – sometimes documentation may fail, but your deep knowledge of the business will enable you to make creative decisions to solve the problem. Always communicate! And value your team – an engaged team won't let go of your hand when the plan fails.

Pior do que um incidente de segurança da informação acontecer, é o seu plano de resposta falhar, entretanto, não é o fim do mundo. É preciso entender algo na segurança da informação que incomoda muita gente, a segurança da informação pode falhar e o plano de resposta pode não ser efetivo e não existir um culpado, e mesmo que existam culpados, não é a ação mais inteligente a criminalização dos mesmos. Respire, é momento de entender algumas coisas, por que o incidente ocorreu? E por que o plano de resposta não foi razoável? E o mais importante, quanto a empresa perdeu em negócio com essa situação. Agora elabore um plano para que esse incidente não ocorra mais, um plano de respostas mais efetivo.

It is only possible to identify points of failure and improvements in incident response processes when we have to act on it. Therefore, it is necessary to recurrently test these plans to generate improvements and understand the flaws in the process. This way, we will have an evolution in the maturity of the process and the guarantee of protection for professionals when a real incident occurs.
If your IRP failed due to a lack of proper training or awareness, it's imperative to address this gap immediately. Organize comprehensive training sessions that are tailored to the specific shortcomings of your team. These sessions should not only cover the technical aspects but also emphasize the importance of communication and adherence to protocols during a security incident. Ensuring that all team members are on the same page and fully understand their roles can significantly improve the effectiveness of your IRP.

It is common for the first development of an incident response plan to generate several problems and not be an assertive result, however it is essential that a first version is created so that through it we can modulate responses according to the organization's reality. In this sense, training both the execution of the plan and the evolution of professionals who work technically is essential for the document to evolve as well as the actions.
When an IRP doesn't work as intended, revising the existing protocols is necessary. This might include updating contact lists, improving escalation procedures, or incorporating new technologies to aid in incident detection and response. It's vital to take into account the nature of the incident and the evolving threat landscape when making these revisions. The goal is to create a more resilient plan that can withstand the challenges of a dynamic cyber environment.

A security incident response plan must be updated on a recurring basis, either by updating contacts, considering the high turnover of professionals in the sector, or by adjustments and improvements through the evolution of the information security architecture and environment. It is essential that we review and integrate new environmental solutions, new segmentations and all period updates.
Sometimes, an IRP may fail due to inadequate tools or technology. Evaluate your current cybersecurity tools and invest in upgrades or new solutions that can better support your IRP. This might mean implementing more sophisticated intrusion detection systems, improving your data backup solutions, or adopting more advanced cybersecurity frameworks. The right tools can make a significant difference in how effectively you can respond to and recover from security incidents.

Responding to an incident can generate a trigger for connectivity with various tools, processes, technologies and areas. Therefore, it is essential to detect the necessary actions and review the tools used to validate whether they meet the necessary behavior during an incident response process. Often through these resources we identify the lack or problem regarding the availability of possibilities that a system offers us.
Building resilience is about more than just having a robust IRP; it's about creating a culture that values continuous improvement and learning from mistakes. Encourage your team to view failures as opportunities for growth. This mindset shift can lead to more proactive behavior, better risk management practices, and a stronger commitment to maintaining high security standards across your organization.

Resilience during an incident response is a fundamental point so that all technical controls and plan descriptions are met. This resilience will be a laborious process with people through learning, culture and appreciation of efforts. This is because it is essential that the people operating the plan have a strong mind to sustain the pressure exerted and outline their strategies accurately.
Finally, continuously monitor the progress of the changes you've implemented. This involves regular testing of your IRP through drills and simulations, as well as staying informed about the latest cybersecurity threats and trends. By keeping a close eye on how your IRP performs under various scenarios, you can make ongoing adjustments and ensure that your plan evolves alongside the threats it's designed to mitigate.
