IRM: Cyber incident management

In today's digital age, businesses and organizations are increasingly reliant on technology and data to operate and deliver services. However, with the rise of cyber threats, such as hacking, malware, and phishing, the risk of data breaches and cyber attacks is also on the rise. That is why awareness training is one of the most important elements an organization can have in their fight against cyber crime.

Incident Response and Management (IRM)

Incident Response and Management (IRM) has become an essential aspect of cybersecurity, aimed at quickly identifying and mitigating the effects of security incidents, minimizing damage, and reducing the risk of future incidents. Having regulations and a focus on your safety helps you fight the cybercrime that is ever-evolving.

The goal for IRM is to identify and detect any cyberthreat that could potentially harm your organization. Furthermore, you want to get the situation under control and limit the damage as much as possible, so you don’t lose crucial and confidential information.

Often, an IRM includes procedures on how to handle potential cyberthreats - and how you should act if and when you are the victim of a cyberattack. This incident response plan should be elaborate and clear to everyone so there is no doubt about how you should react to a cyber attack. It should furthermore also include who is responsible for what, and who you should contact in the case of a cyberattack.

The successful IRM

It can be a bit daunting to make a thorough incident response plan and managing it, so below we highlight the most important aspects of IRM:

  • Preparation involves proactively developing an IRM plan, defining roles and responsibilities, and testing and training the response team.
  • Detection involves monitoring networks, systems, and applications for potential security incidents using various tools and techniques, such as intrusion detection systems, security information and event management (SIEM), and threat intelligence feeds.
  • Analysis involves investigating the incident, collecting evidence, and determining the extent and impact of the attack.
  • Containment involves isolating the affected systems, stopping the attacker's access, and preventing further damage.
  • Eradication involves removing the attacker's access and eliminating any malware or other malicious code.
  • Recovery involves restoring normal operations, analyzing the incident for lessons learned, and improving the IRM plan.

Balance the elements of IRM

If you want an effective IRM, it requires that you balance different elements when utilizing it. For example, speed is critical in detecting and responding to security incidents to minimize damage and prevent data loss. However, you should always be cautious when working fast, since speed may also lead to mistakes. It can lead to mistakes such as:

  • Misdiagnosing the incident
  • Overlooking critical evidence
  • Prematurely restoring normal operations before ensuring the attacker is no longer present.

Another element to remember when dealing with IRM is containment and eradication. While containment is essential to prevent further damage, it may also limit the investigation's scope and prevent the attacker's identification and removal.

Eradication, on the other hand, may require significant effort and resources, such as scanning and cleaning all affected systems, which may impact normal operations and cause downtime for everyone in the organization and not just the affected devices and users.

The ever-evolving cyberworld

As with much cybersecurity, IRM also faces several challenges, such as the ever-evolving nature of cyber threats, the increasing complexity of IT environments, and the shortage of skilled cybersecurity professionals.

As a result, businesses and organizations must continually adapt and update their IRM plans and invest in training and hiring skilled personnel, because the employee is the main target for hackers. Thus, awareness training is essential to mention again, since the employees are the gateway for hackers.

Another essential factor in IRM is considering the impact of security incidents on different stakeholders, such as customers, employees, partners, and investors. For example, a data breach may result in the loss of sensitive customer information, which evidently leads to damage to the organization's reputation, and potential legal and regulatory repercussions. In other words, a security breach is fatal to many companies. Of course many companies get to the other side of the cyberattack but they get a few specks on their reputation.

Transparent communication

To mitigate the impact, businesses and organizations must communicate transparently and promptly with affected parties, offer identity protection and credit monitoring services, and implement measures to prevent similar incidents in the future. Failure to consider the impact may lead to long-term damage to the organization's reputation and financial standing.

Incident Response and Management is a crucial aspect of cybersecurity that requires effective planning, detection, and reaction to the threat. Effective IRM requires balancing several tradeoffs and challenges, such as speed vs. accuracy, containment vs. eradication, and adapting to evolving threats and IT environments.

Moreover, considering the impact of security incidents on stakeholders is essential to mitigate damage to the organization's reputation and financial standing. By investing in IRM, businesses and organizations can minimize the risks of cyber threats and protect their assets and stakeholders' interests. By having IRM you protect the employees of your organization as well as the customers. The incident plan helps you fight hackers and their way into your systems and valuable data, so that everyone can stay protected against the cyberthreat.
