In one embodiment, a method includes accessing a request from a lower privileged process executing on a computing device to access a privileged firmware mode of the computing device and accessing a set of access policies for detecting whether the request is an unauthorized access to the privileged firmware mode. The method further includes determining, based on at least part of a content of the request and on the set of access policies, whether the request to access a privileged firmware mode is authorized; and denying or permitting, based on the determination, access by the lower privileged process to the privileged firmware mode.

Privileged firmware mode protection

Example methods and systems for correlation-based security threat analysis are described. In one example, a computer system may obtain event information that is generated by monitoring a virtualized computing instance supported by a host; and network alert information that is generated by monitoring network traffic associated with the virtualized computing instance. The network alert information may specify security threat signature(s) detected based on the network traffic. The computer system may map the network alert information to threat information that specifies indicator(s) of compromise associated with the signature(s) and perform a correlation analysis based on the event information, network alert information and threat information. Based on the correlation analysis, it is determined whether there is a potential security threat associated with the virtualized computing instance.

Correlation-based security threat analysis

Example methods and systems for a computer system to perform security threat detection are described. In one example, a computer system may intercept an egress packet from a virtualized computing instance to pause forwarding of the egress packet towards a destination and obtain process information associated a process from which the egress packet originates. The computer system may initiate security analysis based on the process information. In response to determination that the process is a potential security threat based on the security analysis, the egress packet may be dropped, and a remediation action performed. Otherwise, the egress packet may be forwarded towards the destination.

Security threat detection based on process information

The disclosure provides an approach for remediating false positives for a network security monitoring component. Embodiments include receiving an alert related to network security for a virtual computing instance (VCI). Embodiments include collecting, in response to receiving the alert, context information from the VCI. Embodiments include providing a notification to a management plane based on the alert and the context information. Embodiments include receiving, from the management plane, in response to the notification, an indication of whether the alert is a false positive. Embodiments include training a model based on the alert, the context information, and the indication to determine whether a given alert is a false positive.
