Word scramble
Unscramble the letters and write each key term on the line.
1
EFITNNOACDIYILT
Only authorised people or systems can read data. Everyone else is kept out, like student marks seen only by the student and teacher. A breach is when someone else sees them.
2
TTINIEYRG
Data stays accurate and unaltered unless an authorised person changes it. Accidental or deliberate changes break it, such as a tampered bank balance.
3
ILLYTBVAAIIA
Authorised users can reach data and systems when they need them, such as a school network that stays up. Attacks and hardware failure can reduce it.
4
RESMOSPINI
A rule that lets an account read, write or execute a file or resource. Read only views it, write can change or delete it, and execute runs it as a program.
5
SESCAC NTROOLC SILT (CLA)
A table attached to a resource, like a file or router, that lists which users or groups may access it and what they can do. If you are not listed, access is denied.
6
ECSASC OLG
An automatic record of who accessed a system or file, what they did and when. It helps spot failed logins and misuse, and holds users accountable for their actions.
7
AHHS
A one-way scrambled value made from a password. A system stores it instead of the real password and checks a login by hashing what you type and comparing. It can't be reversed.
