For Personal Computer
Protection Of Software And Data:
Organizations go to tremendous lengths to protect their programs and data. As might be expected, this includes educating employees about making backup disks, protecting against viruses and so on. Other security procedures include the following.
1. Control Of Access: Access to online files is restricted to those who have a legitimate right to access because they need them to do their jobs. Many organizations have a system of transaction logs for recording all accesses or attempted accesses to data.
2. Audio Controls: many networks have audit controls for tracking which programs and servers were used, which files opened and so on. This creates an audit trial, a record of how a transaction was handled from input through processing and output.
3. People Controls: because people are the greatest threat to a computer system, security precautions begin with the screening of job applications. Resumes are checked to see if people did what they said they are not allowed to wonder freely into the areas not essential to their jobs. Manual and automated controls like input controls, processing controls, and output controls that are used to check if data is handled correctly and completely during the processing cycle. Printouts, printer ribbons, and other waste that may contain passwords and trade secrets to outsiders are disposed of through shredders or locked trash barrels.
Disaster Recovery Plan: A disaster recovery plan is a method of restoring information processing operations that have been halted by destruction or accident. Mainframe computer systems are operated in separate departments by professionals who tend to have disaster plans. Whereas mainframes are usually backed up, many personal computers and even entire local area networks, are not, with potentially disastrous consequences. It has been reported that on average a company loses as much as 3% of its gross sales within eight days sustained computer outage. In addition, the average company struck by a computer outage lasting more than 10 days never fully recovers.
A disaster recovery plan is more than a big fire drill. It includes a list of all businesses functions and the hardware, software, data and people that support those functions, as well as arrangements for alternate locations. The disaster-recovery plan also includes ways for backing up and storing programs and data in another location, ways of alerting necessary personnel, and training for those personnel.
In short there are thousands of security software brands available in the market or on the internet that are free to download and so cheap to buy they can easily protect our PCs from worms.
The security issues can be related to the social responsibility that is compounded when an organization engages in the important tasks. This is due to the large number of stake holders. There are lots of ways that can be used to destroy the security of the system for this purpose various algorithms are used to destroy these attacks. These attacks are provided by the competitors and the employees that can handle all the information related to the organization. One of the security algorithms that is used is DES algorithm but it was broken by some intelligent scientists so an algorithm that is called triple des is discovered that cannot be broken but efforts are continued by the people. The security is very big issue in this world of competition. Every one wants to go ahead by using these illegal means. They used to send spam mails to destroy our email inbox or irritate us by getting some important information from us. Thus security for personal computers is very important.
