Host hardening consists of removing unnecessary applications, locking unnecessary ports and services, tightly controlling any external storage devices that are gonna be connected to the host, disabling unneeded accounts on the system, renaming default accounts and changing default passwords.
What is hardening in cyber security?
Definition(s): A process intended to eliminate a means of attack by patching vulnerabilities and turning off nonessential services.
Why host OS hardening is required?
OS hardening can help you reduce the risk of a successful cyber attack. However, to be truly effective, your OS hardening strategy should be implemented alongside a data backup process. This ensures that you have copies of your data and operational systems, and can use them to restore operations if failure occurs.
What is meant by host security?
Host security describes how your server is set up for the following tasks: Preventing attacks. Minimizing the impact of a successful attack on the overall system. Responding to attacks when they occur.
What is system hardening procedures?

Just like plugins and themes on a website can have vulnerabilities, the software used by the web hosts can also have vulnerabilities. And when that happens, all the websites on the network are vulnerable to attacks.
What are the two methods of case hardening?
To achieve these different properties, two general processes are used: 1) The chemical composition of the surface is altered, prior to or after quenching and tempering; the processes used include carburizing, nitriding, cyaniding, and carbonitriding; and 2) Only the surface layer is hardened by the heating and …
What’s the difference between hardening and case hardening?
The biggest difference between each process is that case hardening creates a thin layer on the surface. Surface hardening hardens the outer surface and keeps the core soft throughout the entire process.
What is the difference between hardening and annealing?
Annealing is a heat treatment process used to soften materials or to obtain other desired properties such as machinability, electrical properties, dimensional stability, etc. Hardening or quenching is the process of increasing the hardness of a metal.
What is hardening process PDF?
Hardening: The main aim of the hardening process is to make steel hard tough. In this process, steel is heated 30° – 40°C above the upper critical temperature and then followed by continues cooling to room temperature by quenching in water or oil. It is the opposite process of annealing.
How many controls NIST CSF?
