SAFTEY AND SECURITY OF ICT SYSTEM AND PROCEDURES FOR BACKUP AND RECOVERY Flashcards
WHY DO YOU NEE TO PROTECT DATA IN ICT SYSTEM
DATA IS INVALUABLE TO A COMPANY AND IF IT WAS LOST THE COMPANY WOULD BE CRIPPLED IN THE SHORT TERM
WHAT ARE THE THREATS TO ICT SYSTEM
CARELESSNESS-A VAST AMOUNT OF DATA IS LOSS DUE TO CARELESSNESS FROM STAFF E.G NOT SAVING WORK AND DELETING A FILE BY ACCIDENT
HUMAN ERROR-FIRE AND FLOOD THEFT OF EQUIPMENT
VIRUS
REASON FOR SECURITY BREACH
PERSONAL GAIN-A STUDENT MIGHT CHANGE THEIR GRADE TO GET INTO UNI
FINANCIAL GAIN-SOMEONE MIGHT HACK THE BANK AND TRANSFER THE MONEY TO THEIR ACCOUNT
SABOTAGE-TO DAMAGE THE REPUTATION OF A COMPETITOR ORGANISATION
TYPE OF THREAT
DATA ACCESS THREATS MEAN DATA IS ACCESSED WHILE BEING COMMUNICATED ACROSS A NETWORK ILLEGALLY AND IS CHANGED BY SOME ONE WHO DON’T HAVE ACCESS
SERVICE THREATS ARE DESIGNED TO STOP THE DATA BEING USED BY THE ORGANISATION IT BELONGS TO BY DISRUPTING THE NORMAL TUNING OF THE SOFTWARE BEGIN USED
MEANS OF CONTROL OF THREATS
DATA ENCRYPTION-ONE WAY IS BY ENCRYPTING THE MESSAGE BY SCRAMBLING THE DATA SO IT CANNOT BE UNDERSTOOD IF INTERCEPTED
HOW ARE ICT SYSTEM PROTECTED
HARDWARE MEASURE
SOFTWARE MEASURE
PROCEDURES
EXPLAIN HARDWARE
USE THINGS LIKE BIOMETRIC TO CONVERT A HUMAN CHARACTERISTICS SUCH AS FINGERPRINT INTO A DIGITAL FORM THAT CAN BE STORED IN A COMPUTER
EXPLAIN SOFTWARE
MAKE PRIVILEGE FOR EACH USER.TELLS THEM WHAT COMPUTER AND WHAT DATA THEY ARE ALLOWED TO ACCESS AND WHAT THEY ARE ALOUD TO DO WITH THE DATA
EXPLAIN PROCEDURES
THESE ARE A SET OF RULES TO MAKE SURE THE DATA CANNOT BE COMPROMISED BY ERROR E.G VALIDATION CHECK
WHAT IS THE DATA PROTECTION ACT 1998
REGULATES HOW PERSONAL DATA IS USED AND PROTECT DATA SUBJECT FROM THE MISUSE OF THEIR PERSONAL DATA
WHAT IS THE COMPUTER MISUSE ACT
THIS BECAME A LAW IN 1990.UNDER THE LAW ANY ACT OF UNAUTHORIZED ENTRY TO ICT SYSTEM AND THE INTRODUCTION OF VIRUS ARE MADE A CRIMINAL ACT
BACKUP STRATEGIES
ANY PERSON OR ORGANISATION THAT STORES DATA NEEDS TO HAVE A BACKUP STRATEGIES IN PLACE.THIS DEPENDS ON WHAT DATA NEEDS TO BE BACKED UP HOW OFTEN IT NEED TO BE BACK UP WHEN DOES IT NEED TO BE BACKUP WHERE WILL THE DATA BE STORED
WHAT IS FULL BACKUP
ALL THE DATA STORED IN YOUR FILES AND FOLDERS WILL BE SAVED.THIS MEANS THAT THEY CAN BE RESTORED QUICKLY IF SOMETHING GOES WRONG.A FULL BACKUP TAKES A LONG TIME.THIS IS WHY ITS DONE ON THE WEEKENDS
WHAT IS DIFFERENTIAL BACKUP
ONLY THE DATA THAT IS DIFFERENT SINCE THE LAST FULL BACK UP WILL BE SAVED.THIS REDUCES THE TIME TO RESTORE THE DATA BECAUSE IT ONLY USES THE PREVIOUS FULL AND DIFFERENTIAL BACKUPS
WHAT IS INCREMENTAL BACKUP
THIS SAVES ALL THE FILES THAT HAVE CHANGED SINCE THE LAST BACKUP.WEATHEVER THAT WAS A FULL OR DIFFERENTIAL BACKUP
