SOFTWARE SHOULD BE PERIODICALLY UPGRADED TO BE ABLE TO DEAL WITH THE NEWLY EVOLVING VIRUSES, JOINTLY BY THE DEPARTMENT / OFFICE AND THE SPECIALIST.

ADMINISTRATION OF THE COMPUTER OPERATION :-- Access to computers should be controlled to ensure that the system is not tampered with or mishandled. For systematic and trouble free operation of the computer system attention has to be paid for this purpose and the user's codes and passwords should be given to the regular operators and the software should incorporate checks to prevent unauthorised access to data and to prevent unauthorised changes in data . Usually in custom built software these checks are placed by the system designers in consultation with the user .In other cases the checks may be put in place on technical advice. To ensure data security while restriction on access is one of the essential requirement, protection against accidental loss of data has to be ensured .In order to ensure this ,backup copies of all Important Computers files should be taken out periodically, so that in case data in the main system is accidentally lost , back up data is atleast available. Back ups should preferably be taken on cartridge tapes , being a more reliable media then floppy diskettes .To reduce the possibility of the accidental loss of data due to virus , suitable software to detect and deactivate viruses , commercially available, should be installed, These software should be periodically upgraded to be able to deal with the newly evolving viruses .Use of floppy diskettes ( which may be contaminated) should be prohibited or controlled centrally.While developing the customised software for Computer based(CBMIS) a detailed analysis and designing of the proposed system in a systematic manner is very essential and these tasks are performed jointly by the department/office .
