The Internet has transformed our lives in many good ways. Unfortunately, this vast network and its associated technologies also have brought in their wake, the increasing number of security threats. The most effective way to protect yourself from these threats and attacks is to be enlightened of standard cybersecurity practices. This article on "What is Computer Security?" presents an introduction to estimator security and its primal concepts.

1. What is Computer Security?
2. Computer Security Threats
3. Why is reckoner security important?
4. Best computer security practices.

What is computer security?

Figurer security basically isthe protection of computer systems and information from harm, theft, and unauthorized use. Information technology is the process of preventing and detecting unauthorized use of your estimator system.

In that location are various types of reckoner security which is widely used to protect the valuable data of an arrangement.

What is Computer Security and its types?

One mode to ascertain the similarities and differences amidst Computer Security is past asking what is beingness secured. For instance,

• Data security is securing information from unauthorized access, modification & deletion
• Application Security is securing an application by edifice security features to prevent from Cyber Threats such equally SQL injection, DoS attacks, data breaches and etc.
• Computer Security ways securing a standalone machine by keeping information technology updated and patched
• Network Security is past securing both the software and hardware technologies
• Cybersecurity is defined as protecting calculator systems, which communicate over the computer networks

It's important to understand the distinction between these words, though in that location isn't necessarily a clear consensus on the meanings and the degree to which they overlap or are interchangeable.

So, Computer security  tin be divers as controls that are put in place to provide confidentiality, integrity, and availability for all components of computer systems. Let's elaborate the definition.

Components of calculator system

The components of a calculator system that needs to be protected are:

• Hardware, the physical role of the reckoner, like the system retentiveness and disk drive
• Firmware,permanent software that is etched into a hardware device'southward nonvolatile memory and is mostly invisible to the user
• Software,the programming that offers services, like operating system, word processor, internet browser to the user

The CIA Triad

Calculator security is mainly concerned with iii main areas:

• Confidentiality is ensuring that information is available only to the intended audience
• Integrity is protecting data from being modified by unauthorized parties
• Availability isprotecting data from existence modified by unauthorized parties

In simple language, figurer security is making sure data and computer components are usable but still protected from people or software that shouldn't access information technology or modify it.

Now moving frontwards with this 'What is Computer Security?" article let's look at the nearly common security threats.

Computer security threats

Computer security threats are possible dangers that can maybe hamper the normal functioning of your computer. In the present historic period, cyber threats are constantly increasing equally the world is going digital. The almost harmful types of computer security are:

Rootkit

A rootkit is a reckoner program designed to provide continued privileged access to a computer while actively hiding its presence. One time a rootkit has been installed, the controller of the rootkit volition be able to remotely execute files and change system configurations on the host machine.

Keylogger

Also known equally a keystroke logger, keyloggers can track the real-time activity of a user on his estimator. It keeps a record of all the keystrokes made past user keyboard. Keylogger is also a very powerful threat to steal people's login credential such equally username and countersign.
