A very prominent example will be SSL/TLS, a security protocol for communications over the internet that has been used in conjunction with a large number of internet protocols to ensure security. Problems in the information system could make it impossible to access information, thereby making the information unavailable. The style and precise wording will be down to organisational and individual standards and preferences. Other ways to ensure information confidentiality include enforcing file permissions and access control list to restrict access to sensitive information. For example, if a Web server is not operational when a customer wants to purchase a product, the Web server has suffered a loss of availability. The triad is comprised of three fundamental information security concepts: Confidentiality Integrity Availability As with any triangular shape, all three sides depend on each other (think of a three-sided pyramid or a three-legged stool) to form a […] Example Availability Requirements. ConfidentialityConfidentiality is about ensuring access to data is restricted to only the intended In the CIA triad, availability is linked to information security because effective security measures protect system components and ensuring that information is available. The model consists of these three concepts: Confidentiality – ensures that sensitive information are accessed only by an authorized person and kept away from those not authorized to possess them. Confidentiality, Integrity, and Availability or the CIA triad is the most fundamental concept in cyber security. The function of "Availability" in Network Security is to make sure that the Data, Network Resources or Network Services are continuously available to the legitimate users, whenever they require it. Moreover, not all security applications require the highest level of uptime. C-I-A stands for Confidentiality, Integrity and Availability – these security concepts help to guide cybersecurity policies. But the cost of such a strategy could be prohibitive. Examples of CIA Triad Applications This is just what it says: examples of how these non-functional requirements could be documented. Depending upon the environment, application, context or use case, one of these principles might be more important than the others. Obviously, deploying the highest level of continuous availability (CA) for all of your security applications across the enterprise would be ideal. This is usually done by implementing data/storage redundancy, data security, network optimization, data security and more. This article is intended for beginners in security or other IT folk, not experts! Availability: The third goal of network security is "Availability". An available-for-sale security (AFS) is a debt or equity security purchased with the intent of selling before it reaches maturity or holding it for a long period should it not have a maturity date. It serves as guiding principles or goals for information security for organizations and individuals to keep information safe from prying eyes. The C-I-A triad (also referred to as I-C-A) forms the basis of information security (see the following figure). Information security revolves around the three key principles: confidentiality, integrity and availability (CIA). Typically, data availability calls for implementing products, services, policies and procedures that ensure that data is available in normal and even in disaster recovery operations.
