Risk Management Framework and Security Categorization Explained

In today's article, we will Delve into the world of risk management frameworks and the process of security categorization. The risk management framework is an essential process that helps organizations identify and manage potential risks to their systems. But before we dive into the complex realm of national security systems, let's focus on the risk management framework process for regular federal systems.

Determining Security Categorization

The first step in the risk management framework process is determining the security categorization for a system. But how do we decide which security categorization to assign? To make this determination, we need to examine the information types associated with the system. In this Context, there are two main information types we'll consider: public information and administrative information.

Public Information Type

If we take the example of a web server, we can categorize it Based on the type of information it disseminates. Public information, as the name suggests, refers to information that is publicly available to everyone, including competitors, customers, and even adversaries. Let's say our web server is used to advertise job vacancies for custodial professionals nationwide. This information is not classified or sensitive in nature but is publicly accessible.

Security Objectives: Confidentiality, Integrity, and Availability

When assessing the security objectives for the system, we consider three main aspects: confidentiality, integrity, and availability. In the case of public information, confidentiality is not applicable because the intention is to make the information widely available. However, we do care about integrity. Any potential corruption or manipulation of the data would impact the organization's reputation and the message conveyed to the audience. Nevertheless, the impact on the organization would be low since there are backup systems in place, and the restoration process is manageable. As for availability, it is crucial for disseminating the information effectively, but even if the system experiences a disruption or loss, the overall impact on the organization remains low.

Administrative Information Type

Apart from public information, there is also administrative information associated with the web server. This refers to the data and functionalities related to system administration, such as managing user logins, administrative privileges, and maintaining the server's backend. Although the exposure of administrative information won't result in significant harm, unauthorized access to this data would still pose a risk. However, since the impact on the organization is low due to the system's backup capabilities and the ability to remove compromised accounts, the overall security categorization for administrative information remains low.

Categorization of Low-Impact Systems

Based on the aforementioned analysis, we can determine that the web server falls under the category of a low-impact system. The impact level reflects the overall security posture of the system, considering factors such as information types, security objectives, and potential consequences for the organization. In the case of low-impact systems, the impact on the organization is minimal, making it easier to manage any security incidents or disruptions effectively.

Categorization of High-Impact Systems

Now, let's contrast the previous example with a system of higher importance. Imagine a system that processes satellite information, revealing classified locations of agents worldwide. In this Scenario, the confidentiality of the data becomes paramount. The compromise of this information could have severe consequences, jeopardizing not only the organization but also the lives of individuals involved. Consequently, all other security objectives, such as integrity and availability, would also be set at the highest level due to the overall importance and sensitivity of the system.

System Description

When categorizing systems within the risk management framework, it is crucial to provide a comprehensive system description. The system description entails documenting all the components and their interconnections. For instance, in the case of our web server, we would describe the underlying technology stack, including details like the utilization of Red Hat Linux Enterprise as the operating system, MySQL as the database management system, and network-attached storage for data storage. Additionally, we would Outline the network architecture and any other pertinent information that contributes to the overall understanding of the system.

Registering the System

Another critical task in the categorization process is registering the system. By registering a system, organizations notify Relevant stakeholders about the existence and purpose of the system. In the context of the Department of Defense, a system registration process known as the Mass (Mission Assurance Category) is often utilized. The Mass registration includes providing the system's name, description, version, and other pertinent details, which are then shared with higher-level authorities like Cyber Command. This registration ensures that the organization remains accountable for the security and management of the system.

Conclusion

In this article, we explored the risk management framework process and the crucial step of security categorization. By considering information types, security objectives, system description, and the registration process, organizations can effectively assess and comprehend the security posture of their systems. Remember, security categorization is an ongoing process that requires continuous evaluation and adjustment to address ever-evolving threats and risks.
