"Weaponization: Next, attackers determine which methods to use to compromise a target endpoint. They may choose to embed intruder code within seemingly innocuous files such as a PDF or Microsoft Word document or email message."

Tunneling is a method of transporting data across a network using protocols that are not supported by that network. Tunneling works by encapsulating packets: wrapping packets inside of other packets. Tunneling within commonly used services is a technique that uses file sharing or an instant messenger client such as Meebo running over HTTP to bypass firewalls or other network restrictions. The data packets are encapsulated within HTTP packets and sent as normal web traffic. This way, the data packets can reach their destination without being blocked or detected by the network. References: What is tunneling? | Tunneling in networking | Cloudflare, What Is Network Tunneling & How Is It Used? | Traefik Labs, networking - What is HTTP tunneling? - Stack Overflow

Prisma Access is a cloud-delivered security platform that provides policy enforcement, secure access, and threat prevention for mobile users and remote networks, ensuring consistent security regardless of location.

Signature-based systems struggle with polymorphic or obfuscated malware, which changes its code to avoid detection. Signature-based detection relies on static databases of known threat signatures, limiting its ability to identify new or unknown threats.

Determining system health using unaltered system data – Active monitoring collects real-time data to assess the current health and performance of systems.

Using probes to establish potential load issues – Active monitoring uses synthetic transactions or probes to simulate user interactions and identify performance or load-related issues before they affect users.

Cortex XDR is a cloud-based, advanced endpoint protection solution that combines multiple methods of prevention against known and unknown malware, ransomware, and exploits. Cortex XDR uses behavioral threat protection, exploit prevention, and local analysis to stop the execution of malicious programs before an endpoint can be compromised. Cortex XDR also enables remediation on the endpoint following an alert or investigation, giving administrators the option to isolate, terminate, block, or quarantine malicious files or processes. Cortex XDR is part of the Cortex platform, which provides unified visibility and detection across the network, endpoint, and cloud. References:

A host-based architecture uses virtual machines (VMs) to run workloads on a shared host, commonly found in public cloud environments. Each VM operates independently with its own OS, making this model suitable for traditional and isolated application deployments.

 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.
