Application (Layer 4 or L4): This layer loosely corresponds to Layers 5 through 7 of the OSI model.

Transport (Layer 3 or L3): This layer corresponds to Layer 4 of the OSI model.

Internet (Layer 2 or L2): This layer corresponds to Layer 3 of the OSI model.

Network Access (Layer 1 or L1): This layer corresponds to Layers 1 and 2 of the OSI model

● Benign: Safe and does not exhibit malicious behavior

● Grayware: No security risk but might display obtrusive behavior (for example, adware,

spyware, and browser helper objects)

● Malware: Malicious in nature and intent and can pose a security threat (for example,

viruses, worms, trojans, root kits, botnets, and remote-access toolkits)

● Phishing: Malicious attempt to trick the recipient into revealing sensitive data

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.
