- Autonomous system (AS) A collection of connected internet routing protocols and devices that are managed and controlled by a single administrative entity. It is used to route traffic within a network and to other networks and to provide network services such as hosting and content delivery. Each AS is identified by a unique Autonomous System Number (ASN) used for routing decisions.
- Autonomous System Number (ASN) A unique identifier assigned to each Autonomous System (AS) for use in internet routing. This number is used to organize and coordinate the global internet infrastructure, allowing for the establishment of unique routing policies and ensuring that data is efficiently and accurately directed across the web.
- Availability The accessibility of a system, function, or piece of data when needed. In the context of secure systems, it is one of the three key elements of the CIA triad (Confidentiality, Integrity, Availability) and represents the commitment to ensure that authorized users have continuous and reliable access to resources and data while simultaneously preventing unauthorized access.
- Avalanche Effect In cryptography, it refers to a desirable property of cryptographic algorithms, where a small change in input leads to a significant and unpredictable change in the output. This effect is essential for the security of encryption schemes; it ensures that the ciphertext is radically different, even with minor alterations to the plaintext, which makes cryptanalysis more difficult.
- ava Network Launch Protocol (JNLP) A protocol that is used to launch Java applets and applications from a web page. It allows the applet or application to be downloaded and run on the user's computer, while also providing security measures to protect the user's system from malicious code.
- Awareness The understanding and recognition of potential security threats, vulnerabilities, and risks. This can involve training and education programs to help individuals and organizations understand how to identify and protect against these threats. For example, a security awareness program may include training on how to spot phishing emails, the importance of strong passwords, and the proper disposal of confidential documents.
