Rules of engagement in audit: A set of guidelines that outline the scope, objectives, and limitations of an audit. They are typically used to ensure that the audit is conducted in a consistent and objective manner and to protect the interests of the organization being audited. Examples of rules of engagement in audit include requirements for documentation, confidentiality, and independence.

Running Key Cipher: A type of cipher that uses a long, pre-determined piece of text (known as the "key") to encrypt and decrypt messages. It is used in cryptography to encode and decode secret messages. Examples of running key cipher include using a book as the key to encrypt a message or using a string of random numbers as the key to decrypt a message.

Runtime: The period when a program or process is running or executing within a system after being loaded into memory. During this period, the program is operational and can interact with system resources (like memory and CPU) and with users. Monitoring and managing runtime is essential for performance optimization, error handling, and ensuring the smooth operation of system processes.
