Abstract: A remote control device (140, 600) controls the operation of an appliance. The remote control device (140, 600) includes a receiver (320) or transceiver (620), a controller (330, 630), and a transmitter (350, 650). The receiver (320) or transceiver (620) receives a network packet that includes at least one command. The controller (330, 630) analyzes the network packet to determine whether the packet is intended for the remote control device (140, 600). The transmitter (350, 650) outputs a signal to control operation of the appliance based on the command when the controller (330, 630) determines that the packet is intended for the remote control device (140, 600).

Abstract: A method (200) and program (100) for inhibiting attack upon a computer (120) is provided. The address (104) of a process (106) is produced (612), and encrypted (616) to produce an encrypted address (518), which is then stored in memory (128). When needed, the encrypted address (518) is retrieved (702) from memory (128) and decrypted (704) to reproduce the original process address (104). The reproduced process address (104) is then verified (708). If the process address (104) is determined (708) to be valid, i.e., there was no attack, then the process address (104) is placed (712) in the program counter (318), and a valid process (106) is executed. If the process address (104) is determined (708) to be invalid, i.e., there was an attack, then the address (108) of a crash and terminate process (110) is placed (716) in the program counter (318) and the computer (120) crashes. A nonce value (512) may be generated (602) and encrypted (616) and decrypted (704) in conjunction with the process address (104).

Abstract: A method and system is provided for detecting correlated connections in an extended connection. A plurality of stepping stone detection algorithms are executed in parallel (400), each of the plurality of stepping stone detection algorithms generating a result.

Abstract: The disclosed technology provides a system and method of securely communicating data. An encryptor located at a transmitter can provide encrypted data to the transmitter. The transmitter can maintain a packet number indicating a particular packet for carrying the encrypted data and a sub-packet number indicating a position within the packet where the encrypted data is to be stored. The encryptor can produce the encrypted data using an encryptor seed generated based on the packet number and sub-packet number. A receiver can maintain a receiver packet number indicating a number of previously received packets and can compute a receiver sub-packet number. The receiver can receive a packet containing encrypted data and can decrypt the encrypted data using a decryptor seed generated based on the receiver packet number and sub-packet number.

Abstract: A system for mapping and translating address information in a network is provided. The system includes a client-side address translator (120) and a server-side address translator (140). The client-side address translator (120) is configured to receive a data packet from a client (110). The data packet includes a first destination address representing the real destination address. The client-side address translator (120) maps the first destination address to another address using a mapping algorithm and transmits the data packet with the via the network (160). The server-side address translator (140) receives the data packet, translates the mapped address information back to the real destination address and forwards the data packet using the real destination address.

Abstract: A system and method for detecting transaction anomalies and information reflecting potential fraudulent activities is disclosed. Data is collected from transactions carried out in a number of business applications such as computer systems, telecommunication systems and security systems. This transaction data is normalized to generate transaction data having consistent format for analysis and/or comparison. User profiles are generated by sorting the normalized data by user and identifying particular user characteristics from the sorted data. Each user profile therefore reflects the behavior of the user as it relates to the business applications. The user profiles and/or predetermined rules are then used to detect anomalies in incoming transactions.

A traceback engine isolates the malicious packet in response to operation of the intrusion detection system (528), wherein the traceback engine utilizes the identified stepping stones to determine the point of entry of the malicious packet.
