Whether it's a multi-national corporation or a local startup, regardless of the nature of the business, cybersecurity is now an integral part of operations. As online threats become more sophisticated, having a robust incident response plan has become paramount. One frequently asked question is, 'What is typically the first step in incident response?' This blog post seeks to highlight and explain the first critical step in incident response: identification and evaluation.

In the realm of cybersecurity, Incident response refers to the process by which organizations handle and manage the fallout of a security breach or cyber-attack.

With the continual rise of sophisticated cyber threats, no organization is immune. In this challenging scenario, Incident response doesn't merely serve as a remedial measure post-breach, but also as a preventive action that can help you predict, evade, and mitigate threats. Knowing 'what is typically the first step in Incident response' is the key to turning the tide in your favor.

Identification: The First Step in Incident Response

The first step in any Incident response plan is identification. This step involves discovering, alerting, and reporting the threat to relevant stakeholders. Without effective identification, the knock-on effects of an attack can spiral quickly, often leading to disastrous consequences.

Underlying Components of Identification

The identification process entails several key components: anomaly and threat detection, reporting, and threat prioritization.

Anomaly and Threat Detection

By employing various cyber defense tools such as firewalls, intrusion detection systems (IDS), and security information and event management (SIEM) solutions, organizations can monitor network traffic and behavior to identify anomalies that may suggest a security incident.

Reporting

Once a potential incident has been detected, it needs to be reported to the appropriate team, typically the Computer Security Incident response Team (CSIRT). Effective and prompt reporting enables the organization to implement its Incident response process without unnecessary delays.

Threat Prioritization

Not all cyber threats carry the same level of risk. Some can be minor, others can have catastrophic consequences. Threat prioritization involves evaluating the perceived risk associated with a particular incident to determine the order and method by which it should be addressed.

Evaluation: The Second Step in Incident Response

With successful identification of a cybersecurity incident complete, we move to the second step of the Incident response process: the evaluation. Evaluation plays a defining role in shaping the organization's response to the incident in terms of strategy and tactics used.

Underlying Components of Evaluation

The evaluation phase involves comprehensive root cause analysis and impact assessment.

Root Cause Analysis

Understanding 'why' and 'how' a cybersecurity incident occurred can prevent similar future incidents. Root cause analysis involves determining the underlying reason for the incident, providing insights to reinforce the cybersecurity infrastructure and avert future attacks.

Impact Assessment

The level of damage caused by a cyber-attack depends on several factors, including the nature of the attack and the vulnerability of the system. Impact assessment helps in determining the degree of this damage, guiding the response strategy and potentially saving the organization from heavy financial losses and reputational harm.

In conclusion, understanding 'what is typically the first step in Incident response' is not just about learning some conceptual step; it's about developing an effective strategy to combat cyber threats. The first steps of identification and evaluation are crucial to ensuring that the right measures can be taken swiftly and effectively. Done right, it can significantly curtail the impact of an attack and support the recovery process, enabling organizations to bounce back faster and more efficiently after a cybersecurity incident.
