CompTIA CySA+ CS0-003 Practice Question

The correct first step in a well-structured incident response plan is to identify and validate the incident. This involves confirming the unauthorized access attempts and gathering initial evidence. Without proper identification, any subsequent steps, such as containment or eradication, may be misdirected. Steps like notifying law enforcement, isolating the affected system, and informing management are important but should occur after proper identification and validation to ensure an appropriate and effective response.
