CIA Triad

CIA triad is a foundational concept in both information security and cybersecurity..

Full Form of CIA:

Confidential, Integrity, Availability..

CIA Triad ensure that information remains secure (confidential), accurate and unaltered (integrity), and accessible to authorized users (availability) throughout its lifecycle.

Lets take an example to understand:

Confidentiality: (Protect from unauthorized access) (Encryption)

You use a strong password to prevent unauthorized access to your computer. Additionally, you encrypt sensitive documents to ensure that even if someone gains access to your files, they can't read them without the decryption key.

Integrity: (Protect from unauthorized modification) (Hashing)

To maintain the integrity of your documents, you regularly check their digital signatures. If someone tries to tamper with a document, the digital signature won't match, indicating that the file has been altered.

Availability: (Always Accessible to Authorized Users) (Backup)

You regularly back up your documents to an external hard drive or cloud storage. In case your computer fails or is compromised, you can access your documents from the backup, ensuring their availability.
