What is cryptography,why it important in cyber security? What are the the best Book for practice cyber security<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

What is Cryptography and Why is it Important in Cybersecurity?<\/strong><\/h3>\n\n\n\n

Cryptography is the practice of securing communication and data by converting it into an unreadable format using mathematical algorithms. It ensures confidentiality, integrity, authentication, and non-repudiation<\/strong> in digital communications. Cryptography is crucial in cybersecurity because it protects sensitive information from unauthorized access, cyber threats, and data breaches.<\/p>\n\n\n\n

Importance of Cryptography in Cybersecurity:<\/strong><\/h4>\n\n\n\n
    \n
  1. Data Protection<\/strong> \u2013 Encrypts sensitive information like passwords, credit card details, and personal data.<\/li>\n\n\n\n
  2. Secure Communication<\/strong> \u2013 Used in emails, messaging apps, and online transactions to prevent eavesdropping.<\/li>\n\n\n\n
  3. Authentication & Identity Verification<\/strong> \u2013 Ensures only authorized users access data (e.g., digital signatures, two-factor authentication).<\/li>\n\n\n\n
  4. Data Integrity<\/strong> \u2013 Ensures data is not altered or tampered with (e.g., hashing algorithms like SHA-256).<\/li>\n\n\n\n
  5. Prevention of Cyber Threats<\/strong> \u2013 Defends against cyber attacks like MITM (Man-in-the-Middle), ransomware, and phishing.<\/li>\n<\/ol>\n\n\n\n
