Cryptography, information assurance, cloud and others: 5 key skills for cyber security professionals

April 15, 2016

Cyber security professionals are in high demand at the moment, but what skills do they need to have to be able to protect your business? Here are a few of the most valuable skills that a cyber security worker can have.

1. Cryptography

Cryptography means practising and studying techniques for secure communications. It is an important method for protecting data stored in computer systems.

Encryption, a major cryptographic technique, involves feeding a communication through an algorithm, effectively scrambling it so that it can only be read by somebody with access to the algorithm, or key.

Encryption is already used in applications such as Telegram, Tor Messenger and WhatsApp.

More generally though, cryptography involves analysing and constructing protocols to prevent third parties from reading private messages.
