The protection of data and programs used in computer system is known as software security. Software security provides barriers and other cyber-tools that protect programs, files, operating systems and the information flow to and from a computer.

Some common software security are:

1. Password Protection

A password is a secret word or phrase that provides uses access to a particular program system. Every software enable you to password-protect a variety of resources. If you use any network features, you should password protect them frequently. Experts advise that you use long password and do not use long passwords that could be easily guessed. Never use blank password.

2. Backup

Backup means to store some copy of programs, operating system, compilers, data, information, etc. permanently in secondary storage devices like hard disk, floppy disk, etc. A simple disk error can do just as much damage as a hacker might do. And even the most experienced computer user occasionally deletes a file or folder by accident. So, backup is very essential.

3. Defragmentation

Defragmentation is the process of rewriting part of a file to contiguous sector on hard disk to increase the speed of processing. As you update your data files over time, they may become fragmented, or divided up into several widely spaced pieces. This can slow down data retrieval if the problems become severe. Using a defragmenter can restore that lost performance.

4. Hard Lock Key

Some software use hard lock key which is connected to one of the ports of the computer. When software is executed it checks for hard lock. If the hard lock key is absent then the software does not execute. This protects the software from pirated use.

5. Virus scanning

Computer viruses are the most effective factor of data and software. Virus may damage our data and software. Virus produces several unusual symptoms in our computer and gives trouble to the user while working with computer. So, we should keep our computer free from virus. For that we should scan our computer regularly using latest and updated anti -virus software.

6. Scandisk

Scandisk is a process, which analyzes and repairs logical and physical disk errors like files, folders, bad sectors and lost chains. It can fix errors on commonly-used data storage devices.

7. Using a Firewall

A firewall's main purpose is to prohibit unauthorized access to your computer via the internet. A functioning firewall is your best defense against hackers or anyone else who might try to reach your PC via the internet. There are various kinds of firewalls both hardware and software and they can use different methods to keep intruders way from your system.

Very Short Questions

The protection of data and programs from being lost or damaged due to accidental or intentional harm is known as data and software security.
Any four data and software security measures are as follows:

  • Password
  • Antivirus software
  • Scandisk
  • Defragmentation

A password is a secret word or a sequence of characters that provides accessibility to a user to access file, application or computer system.
A computer user has to enter user name and password for logging into computers, retrieving e-mail from servers, etc. The password prevents unauthorized users to access a file, application or computer system. In this way, it protects files, application or computer system from unauthorized persons.

The backup system is one of the important data and software security measures which helps to make a duplicate copy of data and software.
When data and software are damaged due to intentional or accidental harm, we can restore data and software from the backup copy. So, backup system helps to protect data and software of a computer.

The defragmentation is the process of rearranging the fragmented files in the contiguous spaces on the disk. When the fragmented files are defragmented, the files and the programs are loaded faster than the previous.

Software prevents data loss by following ways:

1) Antivirus software can detect and remove viruses from computer.
2) Scan disk Checks file, folders, bad sectors and any other errors of specific disk and fix them.
3) Software for backup helps in securing the information by keeping the important computer data or files in another location.

Scandisk is an important utility program that helps to keep a disk in a good working condition. It checks files, folders, bad sectors, lost clusters, lost chains and any errors of the specific disk and it can fix them if it is possible.
