116 results about "VLAN access control list" patented technology

A VLAN access control list (VACL) provides access control for all packets that are bridged within a VLAN or that are routed into or out of a VLAN. Unlike regular Cisco IOS access control lists that are configured on router interfaces and applied on routed packets only, VACLs apply to all packets. The technology was developed by Cisco on the Catalyst 6500 Series switch platform.

Emergency access interception according to black list

This invention addresses to execute an emergency access interception in a widely distributed environment. An access controller 100 manages an access control list (ACL) 110 recording access right to each object, and a black list (BL) 120 recording user information corresponding to the emergency access interception. The access controller 100 receives a request for authentication to access right and judges whether or not the access right is proper, first according to the BL 120 then ACL110. In case where the user information corresponding to the request is recorded in the BL 120, the access controller 100 sends out the user information to other access controllers and instructs them to register it in the black list. This invention effectively actualizes the emergency access interception under the widely distributed environment in case where the interception is required for any user.

Oblivious transfer with hidden access control lists

A method, apparatus, and a computer readable storage medium having computer readable instructions to carry out the steps of the method for anonymous access to a database. Each record of the database has different access control permissions (e.g. attributes, roles, or rights). The method allows users to access the database record while the database does not learn who queries a record. The database does not know which record is being queried: (i) the access control list of that record or (ii) whether a user's attempt to access a record had been successful. The user can only obtain a single record per query and only those records for which he has the correct permissions. The user does not learn any other information about the database structure and the access control lists other than whether he was granted access to the queried record, and if so, the content of the record.

Resource access control

A method and apparatus for enabling multiple application programs to control a system's physical resources by way of multiple resource proxies, while still enabling exclusive control of the physical resource by one application program. Control tokens are used to limit control to one proxy. The proxy having the control token is tracked in an access control list. Java API methods that can alter the state of a physical resource are marked with an access control attribute during grinding. A resource management module intercepts API methods attempting to obtain control of the physical resource. If a proxy controlled by the application program invoking the intercepted method has control the method is allowed to use the proxy to control the physical resource.

Variable domain resource data security for data processing systems

The variable domain data access control system and method described herein use the same variable domain to describe a data security model and a variable domain data model, such as a product configuration model. A variable domain is a set of resource data that can be described using a logical relationship data structure. The variable domain utilizes logical relationship expressions, such as a Boolean logic language, to define resource data in terms of parts, rules and / or attributes, and any other property that can be accessed for viewing, manipulation, or other purposes. The data security model represents an access control list (ACL) that includes security attributes as resource data and uses the same data structure and logical relationship expressions as an associated variable domain data model. An application, such as a configuration engine, can be used to create controlled access to the variable domain data model using the data security model.

Method for service matching of messages by means of access control list (ACL)

The invention relates to a firewall technique, and particularly discloses a method for service matching of messages by means of an access control list (ACL). The method includes that a firewall classifies all IP addresses of the messages, the IP addresses of N types are obtained, the ACL is respectively distributed for the IP addresses of N types, N ACLs are obtained, and the N ACLs respectively record service types which need to be executed by the messages corresponding to the IP address of each type. When receiving the messages, the firewall finds the corresponding ACL in the N ACLs for matching according to the IP addresses of the messages, and therefore the service types which need to be executed by the messages are obtained. The firewall sends the messages to a corresponding service processing module for processing according to the service types which need to be executed by the messages. By means of the technical scheme, when the firewall processes the messages, the ACL needs to be matched only once, and therefore people can know what services the messages need to carry out. By means of the method, the speed of processing the messages is greatly increased.
