Why is encryption critical?

protects sensitive information from cyber threats and ensures privacy during online communication.

Symmetric encryption key usage

Uses one key for both encryption and decryption.

Cryptography and confidentiality

Cryptography helps ensure the confidentiality of private information.

Encryption is the process of transforming plaintext into ciphertext to prevent unauthorized access.

Time to Break Modern Cryptography

In modern cryptography, it can take a billion billion years to try all possible keys of some algorithms.

Secure Hash Algorithm (SHA)

A family of cryptographic hash functions published by the National Institute of Standards and Technology.

Importance of Hashing in Security

Prevents unauthorized access and ensures data integrity.

A function that converts an input into a fixed-size string of bytes.

What is Cybersecurity?

refers to the practice of protecting systems, networks, and programs from digital attacks. The goal is to safeguard data and maintain the confidentiality, integrity, and availability of information.

Ensures that data is kept secret or private. Only those who should have access to information can access it

Ensures data is trustworthy and free from tampering. Data is what we expect it to be.

Ensures that systems, networks, and applications are functioning as they should and that data is reliably available.

Why is Cybersecurity Important?

Protects sensitive data, personal, financial, and organizational data. Prevents cybercrime, such as hacking, data theft, and online fraud. Maintains trust by ensuring the privacy and safety of users in the digital world.
