The implementation of the NIST CyberSecurity Framework is of vital importance for the changes taking place in the landscape of zero-day threats
The NIST CyberSecurity Framework is a guide for businesses and enterprises of good practices for information security. The NIST CyberSecurity Framework proposes a guide, which can adapt to each enterprise e for different needs.
The framework gives enterprises and businesses the possibility of applying the principles and the best practices of risk management to upgrade security and resilience of critical infrastructure. It provides organization and structure for the different insights of our time, with the best practices already adopted across the industry.
The Framework is an approach based on risk to manage cyber security risks and is composed of three parts: Framework Core, Framework Implementation Tiers, and Framework Profiles. Each part of the component of the Framework enforces the connection between business owners and the activities of cyber security.
In its composition, the Framework Core has five concurrent functions and continuous: Identity, Protect, Detect, Respond and Recover.
When placed together these functions give a strategic approach to the high level of the life cycle of risk management for cyber security of an organization. The Framework Implementation Tiers gives the context in which an organization understands the risk of cyber security and the processes established to manage that risk.
The Framework Profile can be defined as an alignment of patterns, guides, and practices of the Framework Core in a particular scenario of implementation. The Framework Profile can be used to identify opportunities for improving cyber security posture by comparing the actual Profile (“how it is”) with the target Profile (“how it will be”).
By being adaptive, the NIST CyberSecurity Framework can detect and respond to the new threats that appear from out of the thin air. This includes ransomware, IoT hacking and other new types of malware. The Risk Management is treated as an ongoing process to identify, assess and respond to risk. To manage risk it is proposed that organizations must understand the probability of occurrence of an event and the impact resulting from it.
This information gives organizations the capability of determining the acceptable risk level for delivering services, which is expressed by its risk tolerance. This understanding gives organizations the capacity of prioritizing the cyber security activities. It is important to adapt so organizations can respond. The NIST CyberSecurity Framework is available for small business, critical infrastructure services and organizations.
As cloud, big data and analytics reach a new level so does the possibility of damages for the health care, power grid, IoT and businesses. The Framework is elaborated in the form of Tier to cover all aspects of information security covering assets and employees best practices. This approach gives organizations the ability to isolate threats, in such way that detection and mitigation do not affect other assets of the organization.
