Software Measures To Protect The Computer System
Computer software, or simply software, also known as computer programs, is the non-tangible component of computers. Software security is an idea implemented to protect software against malicious attack and other hacker risks so that the software continues to function correctly under such potential risks. Security is necessary to provide integrity, authentication and availability. Some of the security measures for the data, information and software are data backup, password protection, virus scanning, defragmentation and scanning a disk.
Data is the most important asset of an organization. The operating system can be reinstalled ans so can applications, but it may be difficult or impossible to recreate your original data. It is essential that you always backup your important information and have a plan for recovering from a system failure. An attacker could crash a computer’s operating system or data may be corrupted or wiped out by a hardware problem. Computers can be lost, stole, or destroyed in a fire or other catastrophe. For such situations, you must take backups of your data from time to time. Backups are the last line of defense against hardware failure, floods or fires, the damage caused by a security breach or just accidental deletion of data.
Password is a special, top secret word that you use to be able to access certain things or places online. The password is a way of providing your identity to make sure that no one is trying to hack into your things. A password policy is set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. The typical password policies are listed below:
Requirements for passwords:
- Minimum seven characters in length.
- Maximum 14 characters in length.
- Must contain English uppercase and lowercase letters.
- Can not contain any part of the user’s user name.
- Can not contain any part of the user’s full name.
Users wanting to strengthen their passwords further can follow these suggestions:
- Do not use words found in the dictionary.
- Do not use proper names.
- Use one or more numbers in the password.
- Use one or more non alphanumeric characters in their password.
- It is strongly recommended that users with access to confidential and/or sensitive data utilize one or more of the suggestions to harden their password beyond the minimum requirements.
Virus Prevention and Protection Policy
Computer viruses are a major threat to any organization that stores critical data on computers. Computer viruses are software programs that are deliberately designed to interfere with computer operation, record, corrupt, or delete data, or spread themselves to other computers and throughout the Internet. Anti-virus software is one of the main defenses against virus infections. It is a computer program that detects, prevents, and take action to disarm or remove malicious software programs, such as viruses and worms. You can help protect your computer against viruses by using antivirus software, such as Microsoft Security Essentials, Quick Heal, Kaspersky, McAfee Antivirus, etc. Anti-virus software covers the main line of attack. It scans incoming emails for attached viruses. It monitors files as they are opened or created to make sure they are not infected.

File fragmentation is a term that describes a group of files that are scattered throughout a hard drive platter instead of one continuous location. Fragmentation is caused when information is deleted from a hard drive and small gaps are left behind to be filled by new data. As new data is saved to the computer it is placed in these gaps, if the gaps are too small the remainder of what needs to be saved is stored in remaining gaps. A defragmenter is a software utility that rearranges the fragments or discontiguous parts of each file stored on a computer hard disk so that the small, empty storage spaces adjacent to fragments can be used, effectively creating new storage space and possibly making file access faster.
ScanDisk is a DOS utility application used to check and correct errors on hard and floppy disks. It was first shipped in DOS 6.2 and was included with Windows 95, 98 and ME. The utility scans disk surfaces for defects and marks those sections to prevent the rewriting of data and data loss. ScanDisk saves recovered lost clusters as .chk files. ScanDisk is automatically activated when rebooting a computer that is not properly shut down, or if it detects initial disk problem,s from the Power On Self Test (POST).
Hardware Measures To Protect The Computer System
Hardware refers to the physical components that make up a computer system. There are many different kinds of hardware that can be installed inside, and connected to the outside, of a computer. The physical destruction of hardware and other equipment may be caused by the misuse or mishandling of equipment. You have to be very careful while handling equipment because it is delicate and is prone to damage.
Hardware security refers to the protection of computers from physical loss and damage. Security of computers from theft, physical damage etc refers to the hardware security. There are various securities measures that helps us to protect computer hardware.
