  6. Cybersecurity is crucial because it protects sensitive data, systems, and networks from cyber threats like hacking, malware, ransomware, and data breaches.

Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.

The purpose of data encryption is to protect information by converting it into a secret code, making it unreadable to anyone who doesn't have the proper decryption key or password.

Key purposes of data encryption:

  1. Confidentiality: Encryption ensures that only authorized individuals can access or read the data. Even if the data is intercepted or stolen, it remains unreadable without the decryption key.

  2. Data Protection: Encryption helps protect sensitive data—such as personal information, credit card numbers, or business secrets—from hackers, identity thieves, and unauthorized access.

  3. Secure Communication: Encryption is used in secure messaging, emails, and online transactions to keep communication private and safe from eavesdropping.

  4. Compliance: Many laws and regulations (like GDPR, HIPAA, and PCI-DSS) require organizations to encrypt sensitive data to protect users' privacy and avoid legal penalties.

  5. Integrity and Trust: Encryption can also help verify that data has not been tampered with, ensuring its integrity. This builds trust between users and organizations.

In simple terms:

Encryption turns readable data (plaintext) into unreadable data (ciphertext) using an algorithm and an encryption key. Only those with the correct key can convert it back to its original form.

Overall, encryption is a critical tool in cybersecurity for protecting data both in transit (e.g., while being sent over the internet) and at rest (e.g., stored on a device or server).
