Abstract: A decentralized security system and associated methods are implemented by a distributed set of security controllers that independently detect threats and implement attack protections for endpoints based on cumulative threat states that are synchronized across the distributed set of security controllers in a decentralized manner. A particular security controller receives different states associated with different hashed identifiers from the other security controllers, and also receives a request from a client that is directed to a particular endpoint. The particular security controller generates a hashed value from hashing an identifier from the request that identifies the particular endpoint, updates a first state based on the first hashed value matching a hashed identifier that is associated with the first state, and implements a protective action in response to an updated value generated from updating the first state violating a security rule.

Abstract: A method (400) for a website authentication is provided. The method includes receiving a reference uniform resource locator (URL) (130) at a browser (120) and determining whether the reference URL adheres to an authentication protocol (202) including a credential identifier (132c) and a web authentication host URL (132a). When the reference URL adheres to the authentication protocol, the method also includes extracting the credential identifier and the web authentication host URL from the reference URL. The method further includes obtaining credential data (160) from a remote service (150) using the credential identifier and sending web authentication instructions (170) to the browser. The web authentication instructions include the web authentication host URL and the credential data.
