An irrigation recirculation system and methods of filtering and cleaning water within the irrigation recirculation system. The system includes an above the ground water source and a fluid flow conduit that conveys the water into a filter element within a basin. The filter element separates solids from the water by causing the water to change direction before continuing on a fluid flow path. The water is then stored and distributed by a self-cleaning storage system that convey the filtered water to sprinkler heads of the irrigation system.

Irrigation water recirculation system

An irrigation recirculation and fire extinguishing system is provided that includes a water collection system, and a fluid conduit configured to receive water from the water collection system such that the water flows through the fluid conduit along a fluid flow path. A water distribution tank is configured to receive the water from the fluid conduit received from the water collection system, and a sprinkler head pump is configured to direct the water toward at least one sprinkler discharge nozzle. A dwelling pump is configured to direct the water toward at least one dwelling discharge nozzle that discharges water onto a dwelling.

Temporary access is provided to enable a service provider to service a customer's system resource such as data processing or communication equipment. A prearranged but dormant user account for the service provider is automatically activated in response to a trigger event such as the opening of a trouble ticket. The account is automatically deactivated upon detecting a closure event associated with the trigger event, such as the closing of the trouble ticket, expiration of a predetermined time interval following detection of the trigger event, or occurrence of a predetermined time. This provides a timely yet secure way for a customer to allow a service provider access to system resources which requires neither a standing open account nor manual opening and closing of a user account for the service provider.

Method for automatically providing a temporary user account for servicing system resources

Performance of a pattern-matching intrusion detection system (IDS) is improved by ranking signatures in its signature table by likelihood of occurrence, so that the table may be searched efficiently. Occurrence data associated with signatures is kept, and the ranking adaptively revised according to updates of the data. When the IDS detects a system event, the signature table is searched. If the search does not find a signature matching the event, thereby suggesting that the event poses no threat, a null signature is added to the signature table in a strategic location to terminate future searches early. In one embodiment, null signatures may be stored in a cache. When a system event is detected, the cache is searched. If a match is not found, the signature table is searched. If a match is not found in the signature table, a null signature is cached.

Intrusion detection method and signature table

A defense against spoofing vandals is provided, where the defense enlists the network-addressable device whose identity is used by the vandal. A network-addressable device checks incoming messages for communication protocol violations that indicate that a spoofer is using the identity of the network-addressable device. When such a protocol violation is detected, the network-addressable device records attributes of the incoming message in a spoofing logbook database. Further, the network-addressable device increments a counter associated with the identity of the spoofer's target. The value of the counter is compared with a predetermined threshold, in order to determine if the supposed spoofing is an isolated incident or part of a persistent attack. When the value of the counter exceeds the threshold, the network-addressable device constructs a spoofing alert, and sends the spoofing alert to a network administrator. The network-addressable device then rejects the message associated with the protocol violation.
