There are a large number of ways in that an organisation can be protected from hackers and viruses:

There are a lot of different anti virus programs available, which when loaded onto your computer can scan the memory and discs for any viruses that could be potentially harmful to your computer. The software would then remove any viruses found. However it is important to regularly update your virus software, as new viruses are being discovered all the time which old pieces of software may not be programmed to check for.

·        Stopping people downloading files/placing files from discs onto the hard drive of the computer – This would be a very effective way of preventing viruses, as no unauthorised or potentially damaging software would be allowed onto the computer, as long as people did keep to the rules.

·        Backing up the system daily – This wouldn’t necessarily stop viruses within the system, but in the event of the system being destroyed then it would be easy to quickly replace everything that has been lost as it would be backed up on discs.

·        Have one stand alone PC where discs can be checked for viruses, therefore if there happens to be a virus on the disc it will only affect the one PC and not bring a whole network down.

·        Using user names and passwords that are unique. Therefore nobody would be able to access the system without authorisation since they would not know these pieces of information.

·        Setting up a firewall on the system. This is a device that would monitor the ports of your computer and block unauthorised access. It can keep track of all data that enters or leaves your network, and even stop this data from doing so, therefore if you did get a virus on your computer you would have monitored when it was received and where it came from.

The advantages of validation:

·        There is less chance of making typing errors as the computer checks all your data for you, and you do not have to look through the document so carefully for errors, therefore this is a timesaver.

 

Disadvantages:

·        Validation rules can take a little time to set up.

·        They also do not guard against typing errors completely.

Input masks allow you to actually design the way that data should be entered into certain fields. Data can be entered exactly how you wish it to be, with capital letters, or brackets, or percentage signs.
