Study Notes
Internet and Cybercrime
- The Internet is a global network connecting millions of businesses, agencies, institutions, and individuals.
- Cybercrime incidents occur at an alarming rate with reports indicating that global financial losses reached around $2 trillion in 2023.
Cybercrime and Hacking
- Cybercrime includes illegal activities done over the Internet, often for financial gain, such as identity theft and social engineering scams.
- Hacking is the unauthorized access to computer systems, which can lead to tampering with data, using system resources, or proving one's capability.
Threats and Vulnerabilities
- Cybersecurity threats can be categorized into natural disasters, accidental threats from user mistakes, and malicious attacks.
- A hacker attack occurs approximately every 39 seconds, averaging 2,244 attacks daily against Internet-connected computers.
Types of Malicious Threats
- Malware: Includes viruses, worms, spyware, adware, trojans, and ransomware that seeks to exploit vulnerabilities.
- Social Engineering: Techniques used by hackers to manipulate users into revealing personal information or following malicious instructions.
- Phishing Attacks: Deceptive attempts to acquire sensitive information by pretending to be a trustworthy entity.
Hacking Classifications
- White Hat Hackers: Ethical hackers working legally to improve security.
- Black Hat Hackers: Malicious hackers engaging in illegal activities.
- Grey Hat Hackers: Individuals who typically obey the law but may breach it for personal gain or experimentation.
Basic Cybersecurity Concepts
- Cybersecurity protects software, hardware, and data stored online, focusing on the common CIA triad: Confidentiality, Integrity, and Availability.
- Unauthorized access prevention is crucial, reinforced through systematic processes and stringent access controls.
Importance of Personal Data Security
- Personal information includes sensitive data like bank details, identifications, and employment history.
- Organizations must ensure fair, lawful processing of personal data, maintaining accuracy and relevance and avoiding unnecessary retention.
Identity Theft Implications
- Identity theft involves impersonating another person's identity for financial gain, leading to significant recovery costs and time to restore one’s identity and credit.
Biometric Security Measures
- Biometric systems utilize unique biological traits for authentication, such as fingerprints and facial features, providing enhanced security compared to traditional passwords.
File Security Protocols
- Files must be secured to protect sensitive business and personal information. Key practices include enabling Macro Security Settings and encrypting documents with passwords.
- Macros can automate tasks but also pose security threats if created with malicious intent.
Concept and Types of Encryption
- Encryption: The process of converting understandable data (plaintext) into an unreadable format (ciphertext) to ensure confidentiality.
- Symmetric Encryption: Uses the same key for both encryption and decryption, resulting in faster processing suitable for large data volumes.
- Asymmetric Encryption: Employs a pair of keys (public and private) for secure communication, enhancing security when sharing data over untrusted networks.
