摘要： A system and method that provides for using source IP addresses and MAC addresses in a network to provide security against attempts by users of the network to use false source IP addresses in data packets. The system and method provide for analyzing MAC addresses and source IP addresses at the datalink (layer 2) level, and to use the information derived from such analysis to block access through a port where a host device is using a false, or spoofed, source IP address in transmitted data packets. Further, the system and method provide for validating initially learned source IP addresses, and for determining whether the number of unsuccessful attempts to validate new source IP addresses exceeds a threshold level, and where the number does exceed the threshold number the system and method can provide for operation in a possible attack mode.

摘要： A system and method that provides for protection of a CPU of a router, by establishing a management port on a router. Hosts which are connected to a non-management ports of the router are denied access to management functions of a CPU of the router. The system and method can utilize an application specific integrated circuit, in conjunction with a CAM-ACL, which analyzes data packets received on the ports of router, and the ASIC operates to drop data packets which are directed to the CPU of the router. This system and method operates to filter data packets which may be generated in attempts to hack in to control functions of a network device, and the operation does not require that the CPU analyze all received data packets in connection with determining access to the control functions of the router.

摘要： Encryption of message content of an e-mail sent by way of a webmail service may be performed in response to activation of a user interface element. The message content may be encrypted using a symmetric key. A public key of a recipient of the e-mail is received from a backend service and employed to encrypt the symmetric key. The encrypted symmetric key and encrypted message content are sent to a recipient by way of the webmail service. Decryption of the encrypted message content may be performed in response to activation of another user interface element. A private key of the recipient is received from the backend service and employed to decrypt the encrypted symmetric key. The symmetric key is thereafter employed to decrypt the encrypted message content.

摘要： A multiple key, multiple tiered network security system, method and apparatus provides at least three levels of security. The first level of security includes physical (MAC) address authentication of a user device being attached to the network, such as a user device being attached to a port of a network access device. The second level includes authentication of the user of the user device, such as user authentication in accordance with the IEEE 802.1x standard. The third level includes dynamic assignment of a user policy to the port based on the identity of the user, wherein the user policy is used to selectively control access to the port. The user policy may identify or include an access control list (ACL) or MAC address filter. Also, the user policy is not dynamically assigned if insufficient system resources are available to do so. Failure to pass a lower security level results in a denial of access to subsequent levels of authentication.

摘要： A system and method that provides for copying ARP replies, and generating data packets which include the ARP reply, and other information such as an identification of the port on the ARP reply was received. These data packets are then transmitted to an ARP collector which stores the ARP reply and port information. The ARP collector then uses this stored information, and analyzes future data packets relative to the stored information to detect occurrences of ARP spoofing. The ARP collector further provides for generating alerts and taking security actions when ARP reply spoofing is detected.

摘要： A person-to-person secure file transfer system includes an originating computer that receives a public key of a recipient from a cloud computing system. The originating computer encrypts a file using a message key, and encrypts the message key using the public key of the recipient. The encrypted file is stored in the cloud computing system. In response to a request from a receiving computer, the cloud computing system decrypts the encrypted message key using a private key of the recipient, decrypts the encrypted file using the message key, and provides the now decrypted file to the receiving computer. In another example, the cloud computing system provides the private key of the recipient and the encrypted file to the receiving computer, which decrypts the encrypted message key using the private key of the recipient and decrypts the encrypted file using the message key.
