Cyber security fundamentals involve understanding key concepts like confidentiality, integrity, and availability, recognizing threats, implementing protective measures, and promoting safe online practices to safeguard sensitive data and systems from cyber attacks.

Types of malware include viruses, worms, Trojans, ransomware, spyware, and adware. Each type operates differently, targeting systems to steal data, disrupt operations, or exploit vulnerabilities for malicious purposes.

Cyber security breaches occur when unauthorized individuals gain access to sensitive data or systems, often resulting in data theft, financial loss, and reputational damage. Effective security measures are essential for prevention.

Types of cyber attacks include phishing (fraudulent communication), denial-of-service (overloading systems), ransomware (data encryption for ransom), man-in-the-middle (intercepting communications), and SQL injection (exploiting databases), each targeting vulnerabilities for malicious intent.

Prevention tips for cyber security include using strong, unique passwords, enabling two-factor authentication, keeping software updated, conducting regular security audits, educating employees about phishing, and backing up data frequently to mitigate risks.

Mobile protection involves securing smartphones and tablets by using strong passwords, enabling biometric authentication, installing reputable security apps, keeping software updated, avoiding public Wi-Fi for sensitive transactions, and regularly backing up data.

Social network security involves protecting personal information on platforms by using strong privacy settings, being cautious about friend requests, avoiding sharing sensitive details publicly, and recognizing phishing attempts or suspicious links.

Prevention software includes antivirus programs, firewalls, anti-malware tools, and intrusion detection systems. These tools protect systems from threats, block unauthorized access, and monitor network activity to safeguard sensitive data and maintain security.

Critical cyber threats include ransomware attacks, data breaches, phishing schemes, advanced persistent threats (APTs), insider threats, and denial-of-service attacks. These threats pose significant risks to data integrity, privacy, and organizational operations.
