File management and standard ways of working.

Keep information secure, e.g. from theft, loss, viruses, fire

You should keep information secured from theft on hard disc failures; you can also keep your information safe from viruses that can wipe all your files off the computer.

The way to keep the information safe is to have a BACK-UP file. A back-up file is a file that has all saved work on it and can be saved under a different name in a different folder or can be saved onto a disc. A floppy disc can also transfer up to 1.44 megabytes of data between computers. You can use hard discs for back-ups because the surface of the disc stores data digitally, CD-ROMs are read only optical discs, DVD’s can hold up to 17 gigabytes of data, Magnetic Tapes are the most common used for back-up devices and Zip or Jaz disc the common removable media all these be used as back-up devices.

We do back-ups so that any lost information that is important we can have a mirror copy of the document saved somewhere else so that nothing will happen to it. The backups should be used with passwords, username.

 

I think backup are helpful because if the computer had a power failure and I haven’t saved my work then it means I would have to do all the again, which means it would take longer then what it would have been if I had saved it in the fist place.

 

Protect confidentiality, e.g. prevent unauthorised access to documents or records

        To protect documents from confidentiality you can use the three main types of data security and they are:

  • Physical security
  • Access security
  • Data security

To protect data using physical security you should follow the 7 SAD-FLAB rules to stay safe with confidentiality and they are:

  1. Serial number
  2. Alarms
  3. Doors
  4. Fire protection
  5. Lock
  6. Avoid
  7. Blinds.

You can use these to protect the hardware because if anything happens you have to spend money on a new hard which is expensive. You can limit the amount of access to any important data by using usernames, passwords and firewalls to stop anyone from hacking into files that don’t have the right to access it.

        To protect data from access security you should limit a person’s use of the network. With this security all authorised users should be given usernames and passwords. This is to stop people from hacking into data bases.

        To protect data using data security files can be password protected to protect the data. So only people who use that data have to use a password to view and amend data.

        With computer security comes drawbacks and they are:-

  • Environmental security
  • Procedural security 
  • Human security
  • Electronic security
