摘要： The present disclosure provides systems and methods for detecting email spam and variants thereof. The systems and methods are configured to detect spam messages and variations thereof for different senders and with slight differences within the message body. In an exemplary embodiment, an incoming message body (m) is converted to a sequence of successive word lengths (Sm): m->Sm, a comparison is performed between the sequence, Sm, and a plurality of stored sequences (Sk) of known spam messages, and the incoming message is flagged as spam based on the comparison. Further, the plurality of stored sequences, Sk, may be continually updated based on user feedback and other spam detection techniques. The systems and methods of the present invention may be implemented through a computer, such as a mail server, through a cloud-based security system, through a user's computer via a software agent, and the like.

摘要： A cloud based system that facilitates inspection of secure content and inexpensively detects the presence of a Man-in-the-Middle attack in a client-server communication is disclosed. Through inspection of the server certificate, no Man-in-the-Middle attack between server and the system is ensured; through inspection and designation of the client certificate, absence of a Man-in-the-Middle attack between the cloud based system and the client is ensured. In this way, the cloud based system can perform its usual policy enforcement functions with respect to secure content while avoiding Man-in-the-Middle attacks.

摘要： Systems, methods and apparatus for a content item inspection. A plurality of portions of a content item are received in a buffer, the buffer divided into a plurality of segments. A partial signature of the content item is computed using the received portions of the content item in a most recently received segment and a partial signature computed for a preceding segment. The computed partial signature is compared against a plurality of partial signatures associated with trustworthy content items. If a matching partial signature associated with a trustworthy content item is found for the computed partial signature, the most recently received segment is allowed to be transmitted to a device that requested the content item.

摘要： Systems, methods and apparatus for tunneling in a cloud based security system. In an aspect, tunnel session data describing authentication and unauthenticated sessions, and location data describing tunnel identifiers for tunnels, locations, and security policies specific to the locations are accessed. Tunnel packets are received, and for each tunnel packet it is determined, from the tunnel identifier associated with the packet, whether a session entry in the session data exists for the tunnel identified by the tunnel identifier. In response to determining that a session entry does not exist in the session data, then a session entry is created for the tunnel identifier, an authentication process to determine a location to be associated with the session entry is performed, and an entry in the location data for the location is associated with the session entry.

摘要： In one general aspect, entity instances are monitored during a first interval, each entity instance being one of several types of entity instances. A first ranked list of entity instances is determined from the entity instances monitored during the first interval. The types of entity instances are ranked in the first list according to the number of times each type of entity instance occurred during the first interval and the first ranked list has a first cardinality of types of entity instances. Entity instances are monitored during a second interval. A second ranked list of entity instances is determined. The second ranked list has the first cardinality of types of entity instances. The first ranked list and the second ranked list are merged into a third ranked list of entities instances. The third ranked list has a second cardinality that is less than or equal to the first cardinality.

摘要： Systems, methods and apparatus for a distributed security that provides authentication and authorization management. The system can include an epoch processor that is used to validate authentication and authorization data that is valid only for an epoch. The epoch processor can maintain a public key that can be used to decrypt the authentication and authorization data during the epoch that the key is valid. The epoch processor can receive a new public key during each epoch. The epoch processor can also determine if the authentication or authorization data was fraudulently generated based on the contents of the data, and verifying whether the data is valid for the epoch in which it was decrypted.

摘要： Systems, methods and apparatus for a distributed security that provides authentication and authorization management. The system can include a state manager that is used to identify and maintain the source associated with a client browser that submits requests to the state manager. The state manager can allow requests that are authorized and request authorization for requests that are not. The state manager can maintain the states associated with each domain to reduce the number of transaction needed to authenticate and/or authorize subsequent requests to the same domain or to different domains.

摘要： Guard tables including absence information are used in a security system to limit the processing of negative queries. A key corresponding to a request to access a network resource is hashed and the output of the hash is a bit position in a guard table. The bit value at the bit position in the guard table is checked to determine if the information to which the key corresponds is absent from a datastore. Further processing of the request can be based on the indicated presence or absence information.

摘要： Methods, systems, and apparatus, including computer program products, for generating or using augmentation queries. In one aspect, a set of phrase terms of a phrase are received in first ordinal positions, and a set of first hashes for each of the phrase terms. Concatenated hashes from the set of first hashes are generated. Hashes of content terms for received content are compared to the concatenated hashes to determine if a phrase is detected in the content.
