A stateless firewall is a network firewall that primarily filters traffic based on source and destination IP address, as well as port numbers and protocols. A stateless firewall does not keep track of the state or context of network connections, and only inspects packet headers. A stateless firewall is faster and simpler than a stateful firewall, but it is less secure and flexible. A stateless firewall cannot block complex attacks or inspect packet contents for malicious payloads. References: What Is a Packet Filtering Firewall? - Palo Alto Networks, Common IP Filtering Techniques – APNIC, What is IP filtering? - Secure Network Traffic Management

 Connectors and interfaces are the components that enable a SIEM to collect, process, and analyze data from various sources, such as Microsoft 365 services and applications1, cloud platforms, network devices, and security solutions. Connectors are responsible for extracting and transforming data from the source systems, while interfaces are responsible for sending and receiving data to and from the SIEM server. Without connectors and interfaces, a SIEM cannot operate correctly and ensure a translated flow from the system of interest to the SIEM data lake. References:

A worm is a type of malware that replicates itself to spread rapidly through a computer network. Unlike a virus, a worm does not need a host program or human interaction to infect other devices. A worm can consume network bandwidth, slow down the system performance, or deliver a malicious payload, such as ransomware or a backdoor123. References: Types of Malware & Malware Examples - Kaspersky, 10 types of malware + how to prevent malware from the start, Computer worm - Wikipedia

A worm replicates through the network while a virus replicates, not necessarily to spread through the network.

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.

DevSecOps takes the concept behind DevOps that developers and IT teams should work together closely, instead of separately, throughout software delivery and extends it to include security and integrate automated checks into the full CI/CD pipeline. The integration of the CI/CD pipeline takes care of the problem of security seeming like an outside force and instead allows developers to maintain their usual speed without compromising data security

As containers grew in popularity and used diversified orchestrators such as Kubernetes (and its derivatives, such as OpenShift), Mesos, and Docker Swarm, it became increasingly important to deploy and operate containers at scale.
