  • Generation of security policies for microsegmented computer networks
    Patent number: 11075950
    Abstract: A computer-implemented method of generating a security policy for a microsegmented computing system is provided. The method includes generating a port service map that indicates inbound packet activity by port for a plurality of network addresses within the microsegmented computing system and a port distribution map that indicates inbound packet activity by port for a plurality of network addresses within the microsegmented computing system, and generating a list of security policy recommendations based on the port service map and/or the port distribution map.
    Type: Grant
    Filed: August 20, 2018
    Date of Patent: July 27, 2021
    Assignee: CA, Inc.
    Inventors: Krishna Kumar Yadav Nukala, Vikas Pullagura, Dharanidhar Sahu, Jagadishwara Chary Sriramoju, Lakshmi Priya Vennapusa
  • Dynamically controlling firewall ports based on server transactions to reduce risks
    Patent number: 10834056
    Abstract: Methods and devices for opening a firewall port for a specified time period are provided. A data packet having a source address and a destination address beyond a firewall transmitted from a process source is intercepted by an interceptor. Responsive to determining, based on the source address, that a firewall port is not open, buffering the data packet. A request comprising an identifier, a protocol identifier, and a time period the firewall port is to be open is transmitted to a firewall controller. The firewall controller authenticates the request based on the identifier and opens a firewall port determined based on the protocol identifier. The interceptor receives an open firewall port notification indicating that the firewall port has been opened and transmits the data packet through the firewall port to the destination address. The firewall controller closes the firewall port when the time period has expired.
