Study Notes
Netiquette
- Netiquette is a set of guidelines for acceptable online behavior, covering email, instant messaging, and web communication.
Computer Security Risks
- Computer security risks are events that could damage or lose hardware, software, data, or processing capabilities.
- Risks can be intentional (cybercrime) or accidental.
Cybercriminal Categories
- Cybercriminals include hackers, crackers, script kiddies, corporate spies, unethical employees, cyberextortionists, and cyberterrorists.
Malware Types
- Virus: Damages files and software without the user knowing.
- Worm: Copies itself and uses system resources.
- Trojan Horse: Masks itself as legitimate software, activating under specific conditions.
- Rootkit: Allows remote control of a computer.
Protection Measures
- Antivirus Software: Detects and removes viruses using techniques like virus signatures and file protection.
- Firewalls: Protect networks from unauthorized access in hardware or software form.
- Denial of Service (DoS) Attacks: Disrupt network access.
- Distributed DoS (DDoS) Attacks: Involve multiple compromised systems.
- Backdoors: Allow attackers to bypass security measures.
Health Concerns in Using Computers
- RSI (Repetitive Strain Injury): Injuries from repetitive motions, including tendonitis and carpal tunnel syndrome.
- CVS (Computer Vision Syndrome): Eye strain and discomfort from prolonged computer use.
- Addiction: Excessive computer use leading to social isolation.
Ergonomics
- Ergonomics is the study of designing comfortable and safe workspaces to improve efficiency and health. This includes proper chair, keyboard, and desk setup.
