What does AFF mean in UNCLASSIFIED

Anti Free Flow (AFF) is a term used to describe the restriction of network traffic from entering or leaving a system without authorization. It is used in different contexts and can be applied to a variety of different types of networks, including computer networks.

AFF should be used when attempting to protect networks from unauthorized access, as well as monitoring malicious activity. It should also be considered for environments where the data being accessed may contain sensitive information such as credit card numbers or other forms of personal information.

AFF works by creating filters or rules that specify which connections are permitted and which connections are blocked. These filters can be dynamic, allowing for changes based on certain criteria, or static, meaning that all matches are accepted regardless of context. Depending on the type of filter created, different levels of security can be achieved.

Some examples of AFF include Access Control Lists (ACLs), Firewalls, Intrusion Detection Systems (IDS), Encryption Protocols and Proxy Servers. All these measures help protect against unauthorized access to data, as well as preventing malicious entities from accessing systems or performing malicious activities within it.

While AFF provides protection against many threats, it is not foolproof and there may be cases when an attacker still manages to gain access due to weaknesses in the filter or protocol being employed. Additionally, if the filters are too restrictive then legitimate users may find it difficult or impossible to gain access due to false positive results with the filters in place.
