Cybercriminals are attackers who act independently or as part of an unlawful organization, such as a crime syndicate or a hacker group. Their main motivation is to make money by exploiting vulnerabilities in systems, networks, or applications. They use various methods, such as ransomware, phishing, identity theft, fraud, or botnets, to steal data, extort victims, or disrupt services. Cybercriminals often target individuals, businesses, or institutions that have valuable or sensitive information, such as financial, personal, or health data. Cybercriminals are constantly evolving their techniques and tools to evade detection and countermeasures. They may also collaborate with other cybercriminals or hire hackers to perform specific tasks. References:

IaaS (Infrastructure as a Service) is a cloud computing model that delivers on-demand infrastructure resources to organizations via the cloud, such as compute, storage, networking, and virtualization1. Customers do not have to manage, maintain, or update their own data center infrastructure, but are responsible for the operating system, middleware, virtual machines, and any apps or data1. Therefore, IaaS gives customers full control over the operating system(s) running on their cloud computing platform, as well as the flexibility to customize and configure their infrastructure according to their needs2. References: What are the different types of cloud computing? | Google Cloud, PaaS vs IaaS vs SaaS: What’s the difference? | Google Cloud

"Remember that a trust zone is not intended to be a “pocket of trust” where systems (and therefore threats) within the zone can communicate freely and directly with each other. For a full Zero Trust implementation, the network would be configured to ensure that all communications traffic, including traffic between devices in the same zone, is intermediated by the corresponding Zero Trust Segmentation Platform."

 A switch is a network device that connects multiple devices on a local area network (LAN) and forwards data packets between them. A switch can be identified by its icon, which is a rectangle with four curved lines on each side. In the attached network diagram, device D is the switch, as it matches the icon and connects three computers to device A, which is another network device. References:

 A cloud native security platform (CNSP) is a set of security practices and technologies designed specifically for applications built and deployed in cloud environments. It involves a shift in mindset from traditional security approaches, which often rely on network-based protections, to a more application-focused approach that emphasizes identity and access management, container security and workload security, and continuous monitoring and response. A CNSP offers three main benefits for cloud native applications:

Agility: A CNSP enables faster and more frequent delivery of software updates, as security is built into the application and infrastructure from the ground up, rather than added on as an afterthought. This allows for seamless integration of security controls into the continuous integration/continuous delivery (CI/CD) pipeline, reducing the risk of security gaps or delays. A CNSP also leverages automation and orchestration to simplify and streamline security operations, such as configuration, patching, scanning, and remediation.

Digital transformation: A CNSP supports the adoption of cloud native technologies, such as microservices, containers, serverless, and platform as a service (PaaS), which enable greater scalability, deployability, manageability, and performance of cloud applications. These technologies also allow for more innovation and experimentation, as developers can easily create, test, and deploy new features and functionalities. A CNSP helps to protect these cloud native architectures from threats and vulnerabilities, while also ensuring compliance with regulations and standards.

Flexibility: A CNSP provides consistent and comprehensive security across different cloud environments, such as public, private, and multi-cloud. It also allows for customization and adaptation of security policies and controls to suit the specific needs and preferences of each application and organization. A CNSP can also integrate with other security tools and platforms, such as firewalls, endpoint protection, threat intelligence, and security information and event management (SIEM), to provide a holistic and unified view of the security posture and risk level of cloud applications.

802.11ax, also known as Wi-Fi 6, is an internet of things (IoT) connectivity technology that operates on the 2.4GHz and 5GHz bands, as well as all bands between 1 and 6GHz when they become available for 802.11 use, at ranges up to 11 Gbit/s. 802.11ax is designed to improve the performance, efficiency, and capacity of wireless networks, especially in high-density environments such as smart homes, smart cities, and industrial IoT. 802.11ax uses various techniques such as orthogonal frequency division multiple access (OFDMA), multi-user multiple input multiple output (MU-MIMO), target wake time (TWT), and 1024 quadrature amplitude modulation (QAM) to achieve higher data rates, lower latency, longer battery life, and reduced interference for IoT 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. References: What Is Zero Trust Architecture? | Microsoft Security, Zero Trust security | What is a Zero Trust network? | Cloudflare, What is Zero Trust Architecture? | SANS Institute, What Is a Zero Trust Architecture? | Zscaler, What is Zero Trust Architecture (ZTA)? - CrowdStrike.

 A zero-day threat is an attack that takes advantage of a security vulnerability that does not have a fix in place. It is referred to as a “zero-day” threat because once the flaw is eventually discovered, the developer or organization has “zero days” to then come up with a solution. A zero-day threat can compromise a system or network by exploiting the unknown vulnerability, and can cause data loss, unauthorized access, or other damages. Zero-day threats are difficult to detect and prevent, and require advanced security solutions and practices to mitigate them. References:
