Study Notes
Intrusion Detection Systems (IDS)
- Monitors system resources and activities, issues alerts when detecting attempts to circumvent security measures
- Two approaches:
- Knowledge-based: Detects specific attacks and system vulnerabilities (e.g., repeated failed login attempts)
- Behavior-based: Models normal system behavior, compares current activity to identify deviations (e.g., unusual traffic at odd hours)
CAN in Automation (CIA)
- International users' and manufacturers' group for Controller Area Network (CAN) protocol
- Established in 1992, provides unbiased platform for CAN development and promotion
Authentication Methods
- Single-factor: Requires one credential (e.g., password)
- Two-factor: Requires two types of credentials (e.g., bank card and PIN)
User Roles and Accounts
- Gives users authority to perform responsibilities within an application, nothing more
Data Encryption
- Protects data within an application from unauthorized access
CIA at the End-User-Level
- Security education
- Authentication methods
- Antivirus software
- Data encryption
