In the art of fingerprinting (also called fingerprinting), this information is used to correlate data sets in order to identify network resources, operating system versions, software programs, databases, and configurations. [starbox] What is network footprinting and how is it related to network fingerprinting?A fingerprint/footprint in cybersecurity is a set of data that can be used to detect operating systems, protocols, software, and hardware of a tech stack. Cybersecurity fingerprinting enables penetration testers and advanced operators to build a server profile by correlating various data sets.
How does a network based IDPS differ from a host based IDPS?A network-based IDPS runs on network segments, including wireless or any other network that is selected. A host-based IDPS, on the other hand, runs on servers.
Why is it important to limit the number of open ports to those that are absolutely essential?It is essential to limit the number of open ports because it adds to the internet-facing systems' attack surface. It does not mean open ports can be hacked easily.
Who does a false positive alarm differ from a false negative alarm from a security perspective which is less desireable?A false positive is a false alarm. A false negative state is the most serious and dangerous state. This is when the IDS identifies an activity as acceptable when the activity is actually an attack. That is, a false negative is when the IDS fails to catch an attack.
