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 aware of standard cybersecurity practices. This article on “What is Computer Security?” presents an introduction to computer security and its key concepts.
Computer security basically is the protection of computer systems and information from harm, theft, and unauthorized use. It is the process of preventing and detecting unauthorized use of your computer system.
There are various types of computer security which is widely used to protect the valuable information of an organization.
One way to ascertain the similarities and differences among Computer Security is by asking what is being secured. For example,
It’s important to understand the distinction between these words, though there isn’t necessarily a clear consensus on the meanings and the degree to which they overlap or are interchangeable.
To become a trusted cybersecurity professional enroll now in the CISSP Certification and get certified.
So, Computer security can be defined as controls that are put in place to provide confidentiality, integrity, and availability for all components of computer systems. Let’s elaborate the definition.
The components of a computer system that needs to be protected are:
Computer security is mainly concerned with three main areas:
In simple language, computer security is making sure information and computer components are usable but still protected from people or software that shouldn’t access it or modify it.
Go through our new Ethical Hacking Training Course to explore more about ethical hacking. This course will teach you the most current hacking techniques, tools and methods that hackers use.
Now moving forward with this ‘What is Computer Security?” article let’s look at the most common security threats.
Computer security threats are possible dangers that can possibly hamper the normal functioning of your computer. In the present age, cyber threats are constantly increasing as the world is going digital. The most harmful types of computer security are:
A computer virus is a malicious program which is loaded into the user’s computer without user’s knowledge. It replicates itself and infects the files and programs on the user’s PC. The ultimate goal of a virus is to ensure that the victim’s computer will never be able to operate properly or even at all.
A computer worm is a software program that can copy itself from one computer to another, without human interaction. The potential risk here is that it will use up your computer hard disk space because a worm can replicate in greate volume and with great speed.
Disguising as a trustworthy person or business, phishers attempt to steal sensitive financial or personal information through fraudulent email or instant messages. Phishing in unfortunately very easy to execute. You are deluded into thinking it’s the legitimate mail and you may enter your personal information.
A botnet is a group of computers connected to the internet, that have been compromised by a hacker using a computer virus. An individual computer is called ‘zombie computer’. The result of this threat is the victim’s computer, which is the bot will be used for malicious activities and for a larger scale attack like DDoS.
A rootkit is a computer program designed to provide continued privileged access to a computer while actively hiding its presence. Once a rootkit has been installed, the controller of the rootkit will be able to remotely execute files and change system configurations on the host machine.
Also known as a keystroke logger, keyloggers can track the real-time activity of a user on his computer. It keeps a record of all the keystrokes made by user keyboard. Keylogger is also a very powerful threat to steal people’s login credential such as username and password.
These are perhaps the most common security threats that you’ll come across. Apart from these, there are others like spyware, wabbits, scareware, bluesnarfing and many more. Fortunately, there are ways to protect yourself against these attacks.
