    Abstract: Techniques for real-time updating of encryption keys are disclosed. In the illustrative embodiment, an encrypted link is established between a local and remote processor over a point-to-point interconnect. The encrypted link is operated for some time until the encryption key should be updated. The local processor sends a key update message to the remote processor notifying the remote processor of the change. The remote processor prepares for the change and sends a key update confirmation message to the local processor. The local processor then sends a key switch message to the remote processor. The local processor pauses transmission of encrypted message while the remote processor completes use of the encrypted message. After a pause, the local processor continues sending encrypted messages with the updated encryption key.

  • Patent number: 12238079
    Abstract: A Software-Defined Networking (SDN)-based “upstream” approach is a controller-based solution that provides secure key distribution and management for multi-site data centers. The approach uses an SDN Multi-Site Controller (MSC) that acts as an intermediary between SDN controllers at sites in a multi-site data center and manages the distribution of keys to sites. The approach is not dependent upon any particular routing protocol, such as the Border Gateway Protocol (BGP), and is well suited for multicast stream encryption by allowing the same key to be used for all replicated packets sent to downstream sites from an upstream source site. The approach distributes keys in a secure manner, ensures that data transferred between sites is done in a secure manner, and supports re-keying with error handling.

  • Patent number: 12231400
    Abstract: A pseudo-active/active firewall configuration handles firewall switchover events with minimized session disconnection. A passive firewall is set to an active state, and an active firewall is switched to a pseudo-active state wherein it continues to process ingress and egress traffic according to traffic handling protocols for its active state. During updating of a corresponding Network Address Translation (NAT) table to route traffic to the now-active firewall, the pseudo-active firewall enters a forwarding state wherein it forwards ingress network sessions to the now-active firewall and processes the ingress network sessions according to its active state. The now-active firewall receives the ingress network sessions and records session states prior to discarding them. After updating the NAT table, when traffic is routed to the now-active firewall, the recorded session states are used to maintain active sessions.

  • Patent number: 12225022
    Abstract: Disclosed embodiments provide systems, methods, and computer-readable storage media for secure data communication between two devices. A disclosed system responds to a request from an originating communication device in a first network to connect with a communication device in a second network, for communication, by receiving a request from the communication device in the first network, the request including payload data and a destination network address in the second network. The system then transmits the received payload data to the destination address in the second network after analyzing the payload data for network intrusion. When the analysis does not indicate network intrusion, the system determines a route to the destination network address by looking up the destination address in a routing table and forwarding the payload data to the destination network address in the second network. If the analysis indicates network intrusion, the system discards the payload data.

Accordingly, the biometric data are encoded as a vector by choosing marker at locations where features are present and, where features are not present, choosing noisy data. The noisy data may be chaff bit values selected collectively from a group of (a) random values and (b) independent and identically distributed values. The biometric public key may be later used to authenticate a subject purporting to be the individual, using a computing facility that need not rely on a hardware root of trust.

  • Patent number: 12192171
    Abstract: A virtual firewall configured with two interfaces assigned different security zones switches between Layer 3 routing and bump-in-the-wire (BITW) modes between sessions. After receiving a packet from a one-arm load balancer, an inner header is determined based on decapsulation which removes an outer header. A route lookup is performed based on the inner header to determine whether to communicate packets of the session with Layer 3 routing or according to the BITW model. The result of the route lookup indicates an egress interface. If the ingress and egress interfaces are the same, the firewall operates according to the BITW model for the session. If the egress and ingress interfaces are different, the firewall routes packets of the session with Layer 3 routing. Upon detection of subsequent packets, the firewall operates according to the determined mode for the session without performing additional inner header route lookups for operation mode determination.

  • Patent number: 12182604
    Abstract: A method for capturing VM resources for forensics includes receiving an indication of compromise (IoC). The indication of compromise indicates an attack is imminent against a virtual machine. The method also includes, in response to receiving the IoC and before the attack begins, snapshotting a memory state of memory used by the virtual machine and increasing a level of auditing of the virtual machine from a standard level of auditing to a heightened level of auditing. The heightened level of auditing generates data representative of all accesses to the memory used by the virtual machine. After the attack against the virtual machine has begun, the method includes maintaining the heightened level of auditing for a threshold period of time, notifying a user of the virtual machine of the indication of compromise, and storing the data in memory external to the virtual machine.
