Study Notes
Security Risks Overview
- Viruses are malicious computer programs specifically designed to cause harm to computer systems.
- Viruses can spread through infected storage devices and by opening emails or attachments containing malicious content.
Types of Security Risks
- Worms and viruses are notable for their ability to replicate themselves, facilitating their spread.
- Worms leverage security network vulnerabilities to propagate, often exploiting weak points in system defenses.
- Unlike worms and viruses, Trojans do not replicate; they disguise themselves as legitimate software to deceive users into downloading them.
Attack Methods and Objectives
- Denial of Service (DoS) attacks aim to incapacitate networks, rendering them non-functional by overwhelming them with requests.
- Spyware discreetly collects user data without their knowledge, posing significant privacy risks.
- Keyloggers monitor and record a user's live actions on their devices, including keystrokes, which can be utilized for malicious purposes.
Identity and Security Fraud
- Phishing is a deceptive practice often employed for identity theft, involving emails that impersonate legitimate entities to solicit sensitive information.
- Identity theft occurs when an individual impersonates another person to obtain benefits, resources, or credit fraudulently.
Summary of Key Security Risks
- Viruses: Malicious programs that cause harm.
- Worms: Self-replicating threats that exploit network vulnerabilities.
- Trojans: Disguised malware without replication capabilities.
- Denial of Service Attacks: Network incapacitation tactics.
- Spyware: Data collection without user consent.
- Keylogging: Capturing user input in real time.
- Phishing: Email-based deception for identity theft.
- Identity Theft: Fraudulent impersonation for illicit gain.
