NIST SP 800-61
Even though information security professionals plan to effectively manage risk, incidents still occur. NIST SP 800-61 is the National Institute of Standards and Technology (NIST) special publication that gives guidelines for organizations on how to handle security incidents. Read section 2.2 on page 6 to learn more about the need for, and the benefits of, an incident response capability. Also read section 3 on pages 21-44 to learn how to appropriately handle information security incidents. Before you move on, make sure you can explain the four stages of the incident response process: preparation; detection and analysis; containment, eradication, and recovery; and post-incident activity.
