Cybersecurity Risks Greater use of technology can increase risks such as: Cybercrime Data theft Security breaches Technology should therefore be used responsibly by protecting privacy, preventing cybercrime, and reducing unnecessary dependence on technology. 6.6 Different Types of Malicious Software and Malware Malicious Software (Malware) Malicious software, or malware, is software intentionally designed to harm, exploit, damage, or gain unauthorized access to computer systems or data. 1. Computer Virus A computer virus is a malicious program that can attach itself to files or programs and spread when the infected file is executed. 2. Ransomware Ransomware is malware that prevents users from accessing their files or systems and demands a ransom/payment to restore access. 3. Trojan Horse A Trojan horse is malicious software that disguises itself as legitimate or useful software to trick users into installing or running it. 4. Phishing Phishing is an attempt to trick people into revealing sensitive information by pretending to be a trustworthy person or organization, often through fake emails, messages, or websites. 5. Hacking Hacking refers to gaining unauthorized access to or manipulating computer systems, networks, or data. 6. Spam Spam consists of unwanted, unsolicited, and often irrelevant messages, such as promotional emails or messages sent in large numbers. 7. Spyware Spyware is software that secretly collects information about a user without their knowledge or consent. 8. Pharming Pharming is redirecting users from a legitimate website to a fake or malicious website without their knowledge. 9. Cookies Cookies are small text files stored on a user's device containing information about their interactions with a website. Example: Cookies can remember login information and website preferences. Cookies themselves are not malware; they are normally used for legitimate website functions. 10. Scam A scam is a deceptive scheme designed to trick people into giving away money, personal information, or other valuable information. 11. Software Piracy Software piracy is the unauthorized copying, distribution, or use of software without proper licensing or permission. Types of Software Based on Availability Freeware Freeware is software available to use without paying a fee. Freeware does not necessarily mean open-source because its source code may remain private. Shareware Shareware is software provided with a free trial or limited functionality. Users may need to purchase it to continue using it or access its full features. Open-Source Software Open-source software has source code that is publicly accessible and can generally be viewed, modified, and redistributed according to its license. 6.7 Information Privacy, System Security and Usability Trade-offs Information Privacy Information privacy means protecting personal information from unauthorized access, use, or disclosure. It ensures that individuals have control over how their personal information is collected, stored, and used. Security–Usability Trade-off There is often a trade-off between system security and usability. Higher security → more restrictions and complexity → lower ease of use. Higher usability → simpler and easier access → potentially lower security. Example: A system requiring strong passwords, 2FA, and frequent verification is more secure but less convenient. Fake News and Disinformation Misinformation / Fake Information False or misleading information that is presented as factual, without necessarily intending to deceive or harm. Disinformation False or misleading information that is deliberately spread to deceive people. Difference Misinformation → False information, not necessarily intentional Disinformation → False information + deliberate intention to deceive Social Networking Social networking is the use of online platforms and websites to connect with people, build relationships, share information, and communicate. Examples Facebook Instagram YouTube WhatsApp X/Twitter Harmful Effects of Social Networking 1. Addiction Excessive use can negatively affect well-being. 2. Cyberbullying Social networks can facilitate harassment, threats, and humiliation online. 3. Privacy Concerns Platforms may collect large amounts of personal data, which can potentially be misused or exposed through security breaches. 4. Spread of False Information Social networks allow information to spread rapidly, including false or misleading information. Social Networking and Fake News Social networking platforms make information easy to share. This is useful for spreading important information but also allows fake news to spread rapidly and widely.
