Especially with the increasing popularity of cloud-based information sharing and storage, data sanitization methods that ensure that all data shared is cleaned has become a significant concern. Therefore it is only sensible that governments and private industry create and enforce data sanitization policies to prevent data loss or other security ...
Email filtering is the processing of email to organize it according to specified criteria. The term can apply to the intervention of human intelligence, but most often refers to the automatic processing of messages at an SMTP server, possibly applying anti-spam techniques. Filtering can be applied to incoming emails as well as to outgoing ones.

Later developments of guards addressed the problem of automatic "downgrading" of information exported from a classified system. The Secure Network Server (SNS) Mail Guard (SMG) enforced source/destination address whitelists, security label checks, attachment type filtering and digital signatures to ensure sensitive information is not released [5]
Crucially, the email would only be decrypted for the end user on their computer and would remain in encrypted, unreadable form to an email service like Gmail, which wouldn't have the keys available to decrypt it. [8] Some email services integrate end-to-end encryption automatically. Notable protocols for end-to-end email encryption include ...

Screenshot of a website blocking the creation of content which matches a regular expression term on its blacklist. In computing, a blacklist, disallowlist, blocklist, or denylist is a basic access control mechanism that allows through all elements (email addresses, users, passwords, URLs, IP addresses, domain names, file hashes, etc.), except those explicitly mentioned.
An example of a data-integrity mechanism is the parent-and-child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically ensures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no ...
