Understanding Cybersecurity: The Importance of the Identify Function
Written on
Chapter 1: The Essence of Self-Awareness in Cybersecurity
Do you truly understand your organization and its personnel? Are you aware of the risks that surround you, as well as your organization's risk tolerance? These inquiries lead us to the Identify function outlined in the NIST Cybersecurity Framework. The ancient adage, “Know thyself,” holds significant relevance here.
Organizations serve as collective entities that embody the individuals within them. According to NIST, comprehending an organization involves understanding its risk profile, potential threats, vulnerabilities, priorities, requirements, and capabilities, all of which fall under the Identify function.
The activities encompassed in the Identify function involve creating an accurate inventory of assets, which includes personnel, data, systems, technologies, vulnerabilities, and applicable laws and regulations, alongside defining acceptable levels of risk. Just as no two individuals are identical, no two organizations are alike. Even within the same sector, such as banking, distinct definitions of risk may exist. While two organizations may deploy similar technologies, their vulnerabilities and risk tolerance may differ dramatically.
When conducting the activities necessary to identify an organization’s characteristics, one may uncover unexpected risks that exceed initial expectations. A thorough understanding of an organization's mission, vision, and strategy is crucial to cultivating a secure environment that fosters success.
In the Identify function, we adopt a comprehensive perspective on the organization, evaluating its people, processes, technology, risks, and compliance obligations, and using this information to inform other cybersecurity functions. This foundational knowledge guides governance processes and shapes how other functions evolve.
Section 1.1: The Intersection of Technology and Cybersecurity
When familiarizing oneself with technology—be it switches, routers, or firewalls—the first three steps typically involve powering on the device, logging in, and issuing a deny-all command. Conversely, when learning about collaborative business tools, the initial steps entail powering on, logging in, and enabling all features. Both approaches are valid.
However, in the realm of cybersecurity, it is imperative to grasp the unique identity of the business being supported. The Identify function necessitates an understanding of an organization's mission, vision, and strategy, which must be applied to forge a secure environment conducive to success. Cybersecurity transcends a rigid framework of rules; it requires a nuanced approach that balances threat mitigation while allowing the business to function effectively.
As organizations strive to deliver meaningful and timely services—whether profit-driven or non-profit—they must possess the agility to navigate risks while fulfilling their core mission.
Section 1.2: The Role of NIST in the Identify Function
The Identify function encompasses both the tangible and intangible aspects of an organization and the technologies it relies on. To facilitate this function, NIST offers valuable guidance and standards. A particularly beneficial resource is NIST Special Publication 800-39, which focuses on managing information security risk through a holistic lens.
Understanding the organization’s mission, values, and acceptable risk levels is essential. Without this clarity, security efforts may misidentify threats, ultimately leading to ineffective application of tools and processes. This situation can be likened to a craftsman who only has a hammer, perceiving every challenge as a nail. However, grasping the business's objectives allows for tailored policies and processes that empower secure operations.
In light of the growing adoption of zero-trust principles, the identity function plays a pivotal role in safeguarding data across its lifecycle. To achieve this, it is vital to understand the data, the systems through which it flows, and the individuals or applications that access it, ensuring robust authentication and authorization processes. Importantly, zero-trust is not merely a deny-all approach; it involves eliminating implicit trust in organizational systems and applications. In zero-trust architecture, we must identify every component of the organization, including its data, access points, risks, and mitigation strategies.
Chapter 2: The Ongoing Nature of the Identify Function

In conclusion, it is crucial not to overlook the importance of the Identify function. This is an ongoing process that must be reassessed regularly. As technology evolves, business objectives change, and new challenges arise, revisiting this function is essential. Failing to treat this—and any other cybersecurity function—as a static procedure can lead to significant vulnerabilities. Schedule regular reviews, especially after major organizational shifts, such as changes in senior leadership. Ultimately, remember to “know thyself.”
