Major Key Concepts Of Computer Security

There are plenty of concepts related to computer security. These concepts are widely used in organizations to secure their network and protect their data. Some of the major key concepts of computer security are mentioned below:

Authentication:

Authentication is a highly important factor to secure any system, which gives access to only authorized users.

There are multiple ways of using an authentication system.

• Username/password: The user has to provide a valid username and password to gain access to the system.
• User card/key: The user has to punch in or enter the right key to access the system.
• Fingerprint/Retina: The user has to give their fingerprint or retina that is registered on the input device to access the information. If the user passes this test, then the system will allow the user to login into the system.

One Time Passwords:

The one-time passwords are more secure than the authentication system, it adds an extra security layer in system security.

When you will try to log in, you have to enter the unique password or OTP that is sent to your email or registered mobile number whenever you login into the system. This OTP or one-time password can be used only once. This can be implemented in the following ways:

• Random numbers: In this type, users will be given cards that are printed with certain alphabets, when the system asked you to enter the numbers that are under the alphabets, you have to enter that alphabet to gain access.
• Secret key: A hardware device is given to the user that is the secret ID which is mapped to the user ID. You need to enter the secret ID if you want to access the system.

Program Threats:

The user programs that are prone to malicious or cyber-attacks are called program threats. There are some of the security threats given below:

• Trojan horse: This captures the credentials of users and sends them to the cyber-criminals or hackers who use your system and take away all the information and data stored on it.
• Virus: Virus is the most common type of cyber-threat that spreads throughout the entire system and corrupt the files. It is a code that is embedded in the system after which the virus starts spreading into the files. It will not allow the user to access the files and programs on the system.
• System threats: The hackers misuse the services and connections on the network to put the user into serious trouble. These threats create a vulnerable environment, thus opening a door for the hacker to misuse the files or operating system resources.

The above-given concepts are just an overview of cyber-security. Hence instead of spending long hours on working complex concepts of cyber-security, it is advised to take the help of assignment writers who will help you to write a perfect assignment.
