The value is to reduce potential inhibitors within the container for information operation. In OCTAVE, the emphasis is on the container level rather than the asset level. Note that the operable target here is information, which includes data from which the information is derived. However, it can also mean physical manifestations such as hard copy documents or even the people who know the information. This references the compute elements and the networks by which they communicate.

Roughly speaking, this is the range of transports and possible locations where the information might reside. The third step is to identify information asset containers. With the application of risk assessment, the level of security investment can be aligned with that individual asset. With an understanding of the asset attributes, particularly the technical components, appropriate threat mitigation methods can be applied. Rather than simply assigning an arbitrary ranking, the system calls for a justification of the prioritization. There are, however, judgment-based attributes such as prioritization. Some of these are simply survey and reporting activities, such as identifying the asset and attributes associated with it, such as its owners, custodians, human actors with which it interacts, and the composition of its technology assets. Within this asset profile, process are multiple substages that complete the definition of the assets. Certainly, the need to protect information does not disappear, but operational safety and continuity are more critical. It is important to stress the importance of process. This profile is populated with assets, a prioritization of assets, attributes associated with each asset, including owners, custodians, people, explicit security requirements, and technology assets. The second step is to develop an information asset profile. (While OCTAVE has more details to contribute, we suggest using the FAIR model, described next, for risk assessment.) The point of having a risk measurement criterion is that at any point in the later stages, prioritization can take place against the reference model. OCTAVE provides a fairly simple means of doing this with an emphasis on impact, value, and measurement.

The first step of the OCTAVE Allegro methodology is to establish a risk measurement criterion. Figure 8-5 illustrates the OCTAVE Allegro steps and phases.įigure 8-5 OCTAVE Allegro Steps and Phases (see ). This approach and the assumptions it makes are quite appropriate, given that many operational technology areas are similarly lacking in security-focused human assets. Allegro assumes that a robust security team is not on standby or immediately at the ready to initiate a comprehensive security review. The version this section focuses on is OCTAVE Allegro, which is intended to be a lightweight and less burdensome process to implement. OCTAVE has undergone multiple iterations. Knowledge of the environment is key to determining security risks and plays a key role in driving priorities. These two systems work toward establishing a more secure environment but with two different approaches and sets of priorities.

#DEFINE OCTAVE SOFTWARE#

OCTAVE (Operationally Critical Threat, Asset and Vulnerability Evaluation) from the Software Engineering Institute at Carnegie Mellon UniversityįAIR (Factor Analysis of Information Risk) from The Open Group In this section, we present a brief review of two such risk assessment frameworks: It must include people and processes, and it should include all the vendor ecosystem components that make up a control system. The key for any industrial environment is that it needs to address security holistically and not just focus on technology. In the utilities domain, the North American Electric Reliability Corporation’s (NERC’s) Critical Infrastructure Protection (CIP) has legally binding guidelines for North American utilities, and IEC 62351 is the cybersecurity standard for power utilities.

In addition, the National Institute of Standards and Technology (NIST) provides a series of documents for critical infrastructure, such as the NIST Cybersecurity Framework (CSF).

#DEFINE OCTAVE ISO#

Also, ISO 27001 is widely used for organizational people, process, and information security management. It consists of a number of parts, including 6 for risk assessments, and 6 for foundational requirements used to secure the industrial environment from a networking and communications perspective. IEC 62443 is the most commonly used standard globally across industrial verticals.

#DEFINE OCTAVE HOW TO#

Within the industrial environment, there are a number of standards, guidelines, and best practices available to help understand risk and how to mitigate it. Formal Risk Analysis Structures: OCTAVE and FAIR
