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.

Signature-based antivirus software is a type of security software that uses signatures to identify malware. Signatures are bits of code that are unique to a specific piece of malware. When signature-based antivirus software detects a piece of malware, it compares the signature to its database of known signatures12. If a match is found, the software can do three things to provide protection:

• Alert system administrators: The software can notify the system administrators or the users about the malware detection, and provide information such as the name, type, location, and severity of the malware. This can help the administrators or the users to take appropriate actions to prevent further damage or infection3.
• Quarantine the infected file: The software can isolate the infected file from the rest of the system, and prevent it from accessing or modifying any other files or processes. This can help to contain the malware and limit its impact on the system4.
• Delete the infected file: The software can remove the infected file from the system, and prevent it from running or spreading. This can help to eliminate the malware and restore the system to a clean state4.
