Computer security, cybersecurity, or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, the disruption or misdirection of the services they provide. The field is becoming increasingly significant due to the continuously expanding reliance on computer systems, the Internet and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of “smart” devices, including smartphones, televisions, and the various devices that constitute the “Internet of things”. Cybersecurity is also one of the significant challenges in the contemporary world, due to its complexity, both in terms of political usage and technology.
How to protect your COMPUTER
The process of securing computers from being damaged due to heat, smoke, dust, dirt, and theft is known as computer security.
TYPES OF COMPUTER SECURITY
Types of computer security On the basis of components of computer system there are two types of computer security:
1. Hardware security
2. Software security
The protection of computer hardware devices from being damaged due to heat and theft is known as hardware security.
HARDWARE SECURITY MEASURES
1. Regular maintenance of computer
2. Use of ID card
4. Free from dust and dirt
5. Protection from fire
6. Protection from theft
7. Use of AC system
8. Use of power protection devices
It is a necessary and important security measure to increase the life of computers. Regular cleaning and maintaining of the computer system can be done to protect our computer hardware system. Dust or vacuum cleaners can be used to clean external and internal hardware devices of the computer for the regular cleaning and maintenance of the computer.
USE OF ID CARD
The use of an ID card in the computer room is necessary for authorized users. It is an important security measure that helps to protect computers from theft and other losses. This measure only allows the authorized person to access the computer room that ensures computer security.
It is another security measure to protect computer hardware. An organization or any individual can get compensation for the loss of the computer from the insurance company. The insurance company will cover all the expenses of the losses of the computers caused by theft, fire, or any other accident.
FREE FROM DUST AND DIRT
Computers must be free from dust and dirt for proper functioning as they can cause overheating which may lead to the destruction of hardware devices. There should be regular cleaning and maintenance to make the computer free from dust and dirt.
PROTECTION FROM FIRE
It is one of the important hardware security measures to protect our computers. Fire can be caused due to various reasons such as short circuits, voltage fluctuations, overload, etc. To prevent fire, the room must have proper wiring and an alarm system to reduce damage caused by fire anytime.
PROTECTION FROM THEFT
The computer is an expensive device so it should be kept in a safe and secure room in order to prevent theft. The computer room must be accessed by an authorized person and monitored by CCTV cameras to prevent theft.
USE OF AC SYSTEM
Proper maintenance of temperature helps to protect computer hardware. Computers in AC rooms get relief in overheating problems that will result in protection of hardware damages that may cause due to overheating.
USE OF POWER PROTECTION DEVICES
Using different power protection devices will help to protect computer hardware from being damaged due to heat and voltage fluctuations. Power protection devices such as UPS, spike guard, voltage stabilizer, etc. can be used for protecting computers from high voltage, overload, and power fluctuations; this will result in the protection of computer systems.
The protection of computer data and software from being damaged or lost is known as software security.
SOFTWARE SECURITY MEASURES
1. Keeping password
2. Regular virus scanning
4. Using ScanDisk
5. Use of firewall
6. Applying the fragmentation
A password is a secret word or string that gives an authorized user access to a particular program or system. Passwords can be used to protect computers by locking the system with a password that leads to the production of the data and software.
REGULAR VIRUS SCANNING
Using an antivirus is one of the important measures to protect our computer data and software. Regular virus scanning should be done to detect and remove viruses from computers. This tool or software is essential for protecting the data and information of the computer systems.
Making duplicate copies of data and software for future use in case of data loss is known as a backup. We can use different backup software for creating backup files and can secure data and software. Backup is necessary to restore lost or deleted files and applications.
Scandisk is the utility software that detects and repairs the error of a hard disk. It is necessary to use the Scandisk program regularly in order to maintain proper working conditions of hard disks and to protect its data.
A firewall is also a software security measure that prevents unauthorized users from accessing the computer or network. Unauthorized access helps to protect from data loss that may be caused by a virus attack or Cyber Attack.
Defragmentation is the process of combining the scattered parts of a file back to a single file and storing them in a single location. Due to frequent creating, deleting, and modifying files fragmentation occurs. So defragmentation is necessary to gather the fragmented files together and to prevent data loss as well as to clean up spaces and speed up computer performance.
