A security manager configured to generate a plurality of learned security policies and provide at least one learned security policy and a security agent to a client machine for enforcement of the at least one learned security policy by the security agent on the client machine. The security manager configured to receive alerts from the security agent indicating anomalous behavior on the client machine.

Intrusion detection and mitigation in data processing

Hypervisors and guest operating systems/virtual machines communicate in virtual environments to enable applications and other services. Security measures are a concern in implementing a secure environment. One feature may include at least one of identifying a session initiation request from a guest operation system at a hypervisor component of a server and receiving periodic messages from the guest operating system, and establishing and maintaining a session and connection between the hypervisor and the guest operating system responsive to receiving the periodic messages from the guest operating system.

Security application for a guest operating system in a virtual computing environment

Evaluating communications via a computer network for the presence of proxy-based communications, by sending to a computer via a computer network multiple data packets followed by an out-of-sequence data packet that is out-of-sequence relative to any of the multiple data packets, receipt of the out-of-sequence data packet configured to cause the computer to send an acknowledgement via the computer network, and to cause the requestor to send a second data request via the computer and the computer network, detecting receipt of the acknowledgement at a first time, detecting receipt of the second data request at a second time, calculating a time delay between the first time and the second time, performing the sending, detecting and calculating steps multiple times for calculating multiple time delays, and determining whether the requestor is communicating via a proxy by evaluating the multiple time delays with respect to a predefined proxy evaluation criterion.

Detecting proxy-based communications

Protecting a computer security application by executing the computer security application on a computer in a first namespace associated with an operating system of the computer, and creating a second namespace associated with the operating system of the computer, where the second namespace is accessible to the computer security application, and where the first namespace is inaccessible from the second namespace.
