Symmetric encryption uses the same key to encrypt and decrypt information. Symmetric encryption is generally faster than asymmetric encryption. However, it has the issue of finding a secure method of sharing the key (e.g., password) for the encryption so that it may be used. Symmetric encryption includes: Block ciphers such as AES (Advanced Encryption Standard), … Continue reading Security: Symmetric / Asymmetric Encryption (Notes)

A risk is where a threat intersects with vulnerability, e.g. where a vulnerability exists and is used by a threat. Threat sources can come in many forms such as: Adversarial e.g., individuals, groups, organisations and … Continue reading Security: Risk Assessment (Notes)
