Certified Cybersecurity Associate Practitioner Paloalto Networks Study Notes

DevOps is not:

● A combination of the Dev and Ops teams: There still are two teams; they just operate

in a communicative, collaborative way.

● Its own separate team: There is no such thing as a “DevOps engineer.” Although some

companies may appoint a “DevOps team” as a pilot when trying to transition to a

DevOps culture, DevOps refers to a culture where developers, testers, and operations

personnel cooperate throughout the entire software delivery lifecycle.

● A tool or set of tools: Although there are tools that work well with a DevOps model or

help promote DevOps culture, DevOps ultimately is a strategy, not a tool.

● Automation: Although automation is very important for a DevOps culture, it alone does

not define DevOps.

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.

A containerized architecture packages software along with its dependencies, libraries, and configuration into an isolated unit called a container. This ensures consistent behavior across environments and simplifies deployment and scaling.

Knowledge-based systems and behavior-based systems are two types of artificial intelligence systems that can be used for security purposes. Knowledge-based systems use a predefined database of rules, facts, and patterns that distinguish “bad” or malicious activities from normal ones. They compare the incoming data with the stored knowledge and flag any anomalies or matches. Behavior-based systems, on the other hand, learn from the observed data and establish a baseline of normal behavior. They then monitor the data for any deviations or changes from the baseline and alert on any suspicious or abnormal activities. References:
