Port hopping is a technique that changes protocols at random during a session to evade detection and analysis by security devices. Port hopping can be used by malware or attackers to communicate with command and control servers or to exfiltrate data. Port hopping makes it difficult to identify and block malicious traffic based on port numbers or signatures.

Mobile Device Management (MDM) enables firewall administrators to remotely and efficiently deploy corporate configurations, such as email accounts and VPN settings, to targeted mobile devices. It ensures consistent policy enforcement and security across all managed devices.

Least privileges access control is the capability of a Zero Trust network security architecture that leverages the combination of application, user, and content identification to prevent unauthorized access. Least privileges access control means that users and devices are only granted the permissions they need to perform their tasks, and nothing more. This helps reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data or resources. Least privileges access control is based on the principle of Zero Trust, which assumes that there are attackers both within and outside of the network, so no users or devices should be automatically trusted. Zero Trust verifies user identity and privileges as well as device identity and security, and requires end-to-end encryption. Least privileges access control also involves careful management of user permissions and network segmentation, which limit the amount of information and length of time people can access something, and contain the damage if someone does get unauthorized access.

Palo Alto Networks Cortex XDR is an extended detection and response platform that provides endpoint protection, threat detection, and incident response capabilities. When an endpoint is asked to run an executable, Cortex XDR does the following steps1:
First, it sends the executable to WildFire, a cloud-based malware analysis and prevention service, to determine if it is malicious or benign. WildFire uses static and dynamic analysis, machine learning, and threat intelligence to analyze the executable and provide a verdict in seconds2.
Next, it checks the execution policy, which is a set of rules that define what actions are allowed or blocked on the endpoint. The execution policy can be configured by the administrator to enforce granular control over the endpoint behavior3.
Then, it runs a static analysis, which is a technique that examines the executable without executing it. Static analysis can identify malicious indicators, such as file signatures, hashes, strings, and embedded resources4.
Finally, it runs a dynamic analysis, which is a technique that executes the executable in a sandboxed environment and monitors its behavior. Dynamic analysis can detect malicious activities, such as network connections, registry changes, file modifications, and process injections4.
