When you use it
Use this when comparing self-replicating malicious programs and their spreading mechanisms.
Watch out
Assuming worms require an existing file to infect. A virus attaches to and infects existing files and programs, whereas a worm spreads across computer networks independently.

When you use it
Use this when distinguishing between personal information rights and technical protection controls.
Watch out
Treating privacy and security as interchangeable. Privacy concerns rights regarding how personal data is handled and used, while security concerns technical measures preventing unauthorized access.

When you use it
Use this to select the appropriate defensive tool for network traffic control versus system malware detection.
Watch out
Relying solely on a firewall for complete virus protection. A firewall filters incoming and outgoing network traffic, but an antivirus program is required to scan and remove malware.

When you use it
Use this to distinguish between failures of confidentiality, integrity, and availability in computer security.
Watch out
Confusing denial of service with a confidentiality breach. Denial of service is a failure of availability, not unauthorized data disclosure.

| Account Type | Access Level | Key Restriction |
|---|---|---|
| Administrator | Full access to settings, software installation, and user management | Only one account on the PC should be an administrator |
| Standard | Can personalize personal settings and run installed applications | Cannot modify system security or access other users files |

When you use it
Use this to determine the permissions, access levels, and restrictions for different Windows user accounts.
Watch out
Using the administrator account for daily use. A daily use account should be a standard account to prevent unintended system changes.
