Cyberterrorists are attackers who use the internet to recruit members to an ideology, to train them, and to spread fear and induce panic. Cyberterrorists may target critical infrastructure, government systems, or public services to cause disruption, damage, or harm. Cyberterrorists may also use the internet to disseminate propaganda, incite violence, or coordinate attacks. Cyberterrorists differ from other attacker profiles in their motivation, which is usually political, religious, or ideological, rather than financial or personal. References: Cyberterrorism, Cyber Threats, Cybersecurity Threat Landscape

East-West traffic is the lateral movement of data packets between servers within a data center, or across private and public clouds1. This type of traffic has grown substantially with the proliferation of data centers and cloud adoption, and it now surpasses the conventional North-South traffic that goes in or out of the network2. Therefore, it is important to protect East-West traffic from potential malicious actors and breaches, as threats can arise internally and move laterally without ever touching the traditional network perimeter12. By inspecting and monitoring all East-West traffic, organizations can effectively block the lateral movement of threat actors, increase network visibility, protect vital applications and data, and lower costs and risks for distributed operations23. References:

Account discovery is a technique in the MITRE ATT&CK framework under the Discovery tactic. It involves adversaries attempting to identify user accounts on a system or network.

Credential access, lateral movement, and resource development are tactics — high-level objectives an attacker is trying to achieve.

Prisma Cloud comprises four pillars:

● Visibility, governance, and compliance. Gain deep visibility into the security posture of

multicloud environments. Track everything that gets deployed with an automated asset

inventory, and maintain compliance with out-of-the-box governance policies that

enforce good behavior across your environments.

● Compute security. Secure hosts, containers, and serverless workloads throughout the

application lifecycle. Detect and prevent risks by integrating vulnerability intelligence into

your integrated development environment (IDE), software configuration management

(SCM), and CI/CD workflows. Enforce machine learning-based runtime protection to

protect applications and workloads in real time.

● Network protection. Continuously monitor network activity for anomalous behavior,

enforce microservice-aware micro-segmentation, and implement industry-leading

firewall protection. Protect the network perimeter and the connectivity between

containers and hosts.

● Identity security. Monitor and leverage user and entity behavior analytics (UEBA) across

your environments to detect and block malicious actions. Gain visibility into and enforce

governance p

A Host-Based Intrusion Prevention System (HIPS) is installed directly on an endpoint device (such as a server or workstation) and monitors local system activity, including processes, file access, and system calls, to detect and prevent malicious behavior.

An Advanced Persistent Threat (APT) is a long-term, targeted cyberattack where data exfiltration is often the primary objective. Attackers maintain a covert presence in the network to steal sensitive information over time.

Cloud-native security is the integration of security strategies into applications and systems designed to be deployed and to run in cloud environments. It involves a layered approach that considers security at every level of the cloud-native application architecture. The four C’s of cloud-native security are123:

Code: This layer refers to the application code and its dependencies. Security at this layer involves ensuring the code is free of vulnerabilities, using secure coding practices, and implementing encryption, authentication, and authorization mechanisms.

Container: This layer refers to the lightweight, isolated units that encapsulate the application and its dependencies. Security at this layer involves scanning and verifying the container images, enforcing policies and rules for container deployment and runtime, and isolating and protecting the containers from unauthorized access.

Cluster: This layer refers to the group of nodes that host the containers and provide orchestration and management capabilities. Security at this layer involves securing the communication between the nodes and the containers, monitoring and auditing the cluster activity, and applying security patches and updates to the cluster components.

Cloud: This layer refers to the underlying infrastructure and services that support the cloud-native applications. Security at this layer involves configuring and hardening the cloud resources, implementing identity and access management, and complying with the cloud provider’s security standards and best practices.

The correct order of the four C’s from the top (surface) layer to the bottom (base) layer is code, container, cluster, cloud, as each layer depends on the security of the next outermost layer. References: What Is Cloud-Native Security? - Palo Alto Networks, What is Cloud-Native Security?

Routing protocols are defined at the network layer (Layer 3) of the OSI model. The network layer is responsible for routing packets across different networks using logical addresses (IP addresses). Routing protocols are used to exchange routing information between routers and to determine the best path for data delivery. Some examples of routing protocols are BGP, OSPF, RIP, and EIGRP. Palo Alto Networks devices support advanced routing features using the Advanced Routing Engine1.
