what is usable security?

Usable security refers to the design and implementation of security measures that are effective while also being user-friendly and easy to use. It involves balancing security requirements with user experience to ensure that security measures do not hinder usability and do not make it difficult or frustrating for users to perform their tasks. Usable security aims to ensure that security measures are designed in a way that encourages users to follow security protocols and guidelines, rather than ignoring them or finding ways to circumvent them. It is an important aspect of cybersecurity because it helps to reduce the risk of security breaches caused by user error or non-compliance.
