Introduction to incident response

IR is the process by which an organization handles situations such as data breaches, distributed denial of service (DDoS), and ransomware attacks. It is an effort to immediately identify an attack, mitigate the impacts of the attack, contain any damage caused by the attack, and fix the cause in order to reduce the risk of future attacks. In practice, IR refers to a collection of information security rules, processes, and tools that can be used to detect, contain, and remove intrusions. Let’s discuss the two most popular IR frameworks, the National Institute of Standards and Technology (NIST) and SANS, as shown in the following diagram.
