Incident Response Team
An incident response team (IRT) or emergency response team (ERT) is a group of people who prepare for and respond to an emergency, such as a natural disaster or an interruption of business operations. Incident response teams are common in public service organizations as well as in other organizations, either military or specialty. This team is generally composed of specific members designated before an incident occurs, although under certain circumstances the team may be an ad hoc group of willing volunteers.

Indicator of Compromise
Indicator of compromise (IoC) in computer forensics is an artifact observed on a network or in an operating system that, with high confidence, indicates a computer intrusion. Typical IoCs are virus signatures and IP addresses, MD5 hashes of malware files, or URLs or domain names of botnet command and control servers. After IoCs have been identified via a process of incident response and computer forensics, they can be used for early detection of future attack attempts using intrusion detection systems and antivirus software.

ISO 27001
ISO/IEC 27001 is an international standard on how to manage information security. The standard was originally published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005 and then revised in 2013. It details requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS) – the aim of which is to help organizations make the information assets they hold more secure.
