What are the types of security in the computer?

Computers are so important to every person in the modern world, all professional people and students use computers for studies and work. Computer Security means protecting our computer and its data from damage, theft, or misuse. It includes the securing of computer hardware and software and maintaining the working condition of computers. Computer security, also known as cybersecurity or information technology security, is the security of computer systems and networks against data hackers, misuse of their hardware, software, or electronic information; it is the method of preventing and detecting unauthorized use of your computer systems. Cyber-security can also be defined as controls that are kept in place to impart accessibility, confidentiality, and unity for discrete components of computer systems; it makes the system secure enough to be trusted. It means that the software is as required as it is, if not at the highest, secure level. It can be measured, and you will use security property as a unit. Different features of code and policy become properties that can be classified into integrity, secrecy, availability, and reliability. It measures these properties at runtime, while the units are decided at design specification. Computer security protects computers and information; it depends on what you want to secure. Either there is a personal computer or protection of all computers in an organization and company. In the case of personal computers or laptops, security usually protects data or IP addresses so that no one can misuse them.

To secure a computer, many things can be used.

Application-Security

App security is the kind of security that develops applications by adding security items to keep them safe from cyber-attacks. Several application security tools and methods, such as firewalls, prevent unauthorized Internet users from accessing personal networks connected to the Internet, especially intranets.

Antivirus software that can block, detect, and remove malware. And encryption is the process of converting standard plain text into incomprehensible texts and vice-versa.

Network-Security

Network security is another kind of computer security that prevents and protects against unauthorized intrusion into computer networks. It is a set of rules and layouts designed to protect the confidentiality and accessibility of computer networks system and information using technologies. There are several components to improve network security, like Wireless Security, which protects the wireless network itself from adversaries to hurt the confidentiality, integrity, or availability of the network.

VPN (a virtual private network) is a code connection over the Internet from a device to a network. The connection helps be sure that sensitive data is safely transmitted. It keeps the unauthorized person from recording the traffic and permits the user to work remotely.

NAC ( Network Access Control ) efforts to unify endpoint security technology uses a set of rules of conduct to define and apply a policy that describes how to secure access to the network by devices when they originally attempt to access the network.

Internet-Security

Internet security is a significant type of computer security that has been defined as a process to make a set of rules and activities to protect a computer’s system that is joined to the Internet. It is a branch of computer security that cope whit specifically with internet-based threats like:

Hacking refers to actions that exploit a computer or a network to gain unauthorized access or control over systems for illegal purposes. A Hacker exploits the vulnerability in computer systems or networks to get access to the system.

Two-way authentication

Two-factor authentication adds steps of security to the authentication process by making it harder for attackers to get access to devices or accounts. It provides forceful security for Google Account by requiring a second verification step when somebody signs in. In addition to the password, they will also need a code generated by the Google Authenticator app on the phone.

Secure password

Make a difficult and strong password so that no one can hack or guess your password. The best passwords include. A password should consist of at least 15 characters, a combination of Capital letters, numbers, and Special symbols. And shouldn’t conclude any of the user’s data like home address, date of birth, or phone number.

Regular updates

Always keep your computers and all their software updated. Many updates contain additional defenses against cyber-attacks. This will protect your system from threats. Select auto-update for software computers, when possible, to regularly check for and apply available updates.

- There are several computer security threats such as Trojans, viruses, Adware, Malware, and much more. If you are searching about types of security threats or malware, they are as below:

1. COMPUTER VIRUS

A Computer Virus is a malicious program that replicates itself and affects the files and programs of the system and can make them non-functional.

2. COMPUTER WORMS

A computer program that spreads malicious codes, computer worms use the network to send copies of the original regulations to other computers. It can also utilize the email of the user and go through documents.

3. SCAREWARE

Malware tricks victims into buying the software by displaying fake virus alerts. A scareware-infected computer might get pop-ups of fake malware threats, and to get rid of those, users are prompted to purchase an unreal anti-malware software.

4. KEYLOGGER

Also known as a keystroke logger, Key loggers can track the real-time activity on the computer. It runs in the background, records all keystrokes made by a user, passes the data to the hacker, and steals passwords and banking details.

5. ROOTKIT

A rootkit is dangerous as it shows legitimate files and deceives the computer user. It masks viruses and worms and makes them appear as necessary files. These are very hard to remove, and only an antivirus with the anti-rootkit item can remove a rootkit.

- Here are some tips of security to make a computer system or network more secure.

1. One of the critical things you can do is protect the wholeness of your data by making regular backups, encrypting confidential data, and deleting other information stored on your computer.

2. Disable auto-login and password protect your screen saver or log out of your computer when you don’t use it.

3. If you have a desktop computer, turn it off completely before leaving it.

4. Do not leave keys for the file locker or security cables near your desk. Put it in a place that you can’t find easily.

5. During the day, it is vital to use a security cable to lock down portable tools, such as a laptop, even while working on them. It can secure your devices all the time.

6. Do not rely on a security cable overnight. In place, store portable devices in a locked cabinet.

7. Lockdown other valuable tools such as desktop computers, scanners, and printers.

8. Keep doors and windows locked when not in your office.

9. Keep computer equipment out of plain sight of windows.

10. make a note of the serial numbers of your equipment and keep it in a safe place so you can easily report it to the police.

11. If you are traveling, keep your computer with you rather than putting it into checked luggage.

12. You can make your computer more secure if you download, install everything from reputable sources, use good antivirus and anti-malware tools

Summary

Computer systems are confronted by various threats related to security. Most computers contain confidential data, and it can cause potential damage to the owner if it gets hacked by criminals. Computer hackers developed many advanced methods to collect data from databases, which they use to harm others. Depending on the threat, it is necessary to ensure security to protect your data, network, and systems. As mobile, laptops and computers, are becoming more and more popular. Theft of computers is on the increase. There is not much you can do to keep a thief safe from stealing your computer, but there are several methods you can take to reduce your chances of becoming a goal significantly. Data stored within the computers are essential; there are saved passwords or bank credentials in browsers that need to be secured. If the computer does not have an antivirus or is not updated, the computer presents a weakness or a vulnerability that can be exploited to cyber threats.
