Examples of serverless environments include Amazon Lambda and Azure Functions. Many PaaS offerings, such as Pivotal Cloud Foundry, also are effectively serverless even if they have not historically been marketed as such. Although serverless may appear to lack the container-specific, cloud native attribute, containers are extensively used in the underlying implementations, even if those implementations are not exposed to end users directly.

The IP stack adds source (sender) and destination (receiver) IP addresses to the TCP segment (which now is called an IP packet) and notifies the server operating system that it has an outgoing message ready to be sent across the network.

Cortex XDR is an endpoint tool or agent that can enact behavior-based protection. Behavior-based protection is a method of detecting and blocking malicious activities based on the actions or potential actions of an object, such as a file, a process, or a network connection. Behavior-based protection can identify and stop threats that are unknown or evade traditional signature-based detection, by analyzing the object's behavior for suspicious or abnormal patterns. Cortex XDR is a comprehensive solution that provides behavior-based protection for endpoints, networks, and cloud environments. Cortex XDR uses artificial intelligence and machine learning to continuously monitor and analyze data from multiple sources, such as logs, events, alerts, and telemetry. Cortex XDR can detect and prevent advanced attacks, such as ransomware, fileless malware, zero-day exploits, and lateral movement, by applying behavioral blocking and containment rules. Cortex XDR can also perform root cause analysis, threat hunting, and incident response, to help organizations reduce the impact and duration of security incidents.Reference:

An evil twin is a type of Wi-Fi attack that involves setting up a fake malicious Wi-Fi hotspot with the same name as a legitimate network to trick users into connecting to it. The attacker can then intercept the user's data, such as passwords, credit card numbers, or personal information. The victim initiates the connection by choosing the fake network from the list of available Wi-Fi networks, thinking it is the real one. The attacker can also use a deauthentication attack to disconnect the user from the legitimate network and force them to reconnect to the fake one.Reference:

'Or split tunneling can be configured to allow internet traffic from the device to go directly to the internet, while other specific types of traffic route through the IPsec tunnel, for acceptable protection with much less performance degradation.'

Endpoint antivirus software is a type of software designed to help detect, prevent, and eliminate malware on devices, such as laptops, desktops, smartphones, and tablets. Endpoint antivirus software can block viruses that are not seen and blocked by the perimeter firewall, which is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules. Perimeter firewall can block some known viruses, but it may not be able to detect and stop new or unknown viruses that use advanced techniques to evade detection.Endpoint antivirus software can provide an additional layer of protection by scanning the files and processes on the devices and using various methods, such as signatures, heuristics, behavior analysis, and cloud-based analysis, to identify and remove malicious code123.Reference:

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.

The diagram displays a mesh topology, where each device is connected to every other device in the network. This topology is characterized by the multiple connections each node has, ensuring there is no single point of failure and providing redundant paths for data transmission, enhancing the reliability and resilience of the network.Mesh topology is one of the types of LAN technology that uses ethernet or Wi-Fi to connect devices12.Reference:
