NIST Elements
The NIST core are desired setting composed of five functions, 23categories, and 108 subcategories alongside their informative references. The framework assists organizations to have a holistic view of their cybersecurity system and make high level decisions easily. The five functions are mainly applicable to management of risks and include Identify, Protect, Detect, Respond and Recover. The categories are widely spread across these functions and cover issues on cyber, physical, and personnel, with the consideration of business outcomes. It is through these functions that cybersecurity activities comply with laws, regulations, and requirements (Keller, 2018). The identify function focuses on the business context and develops cybersecurity risks based on its six categories: Asset Management, Business Environment, Governance, Risk Assessment, and Risk Management Strategy, Supply Chain Risk. The Protect function considers potential cybersecurity events and creates guidelines to safeguard and ensure continued delivery of infrastructure services. The categories within this section include Identity Management and Access Control, Awareness and Training, Data Security, Information Protection Process and Procedures, Maintenance, and Protective Technology (NIST, 2018). The Detect Function offers steps that aid in the timely discovery of cybersecurity events through its categories: Anomalies and Events, Security Continuous Monitoring, and Detection Processes. The respond function involves reaction measures in case a threat is detected. The categories include respond planning, communications, analysis, mitigation, and improvements. Finally there is a respond function that upholds the system after it has been impaired by a cybersecurity incident. The categories in this function involve recovery planning, improvements, and communications. The subcategories give an in-depth view of the system and offers options to modify the cybersecurity program. In general, the functions are the backbone to the NIST elements and hold an organizations cybersecurity program.
