Peer review is a process in which experts in a particular field evaluate the quality, accuracy, and validity of a work, such as a scientific paper or research study, before it is published or shared publicly. This evaluation helps ensure that the work meets established standards, is free from significant errors, and contributes valuable knowledge to the field. In cybersecurity, peer review is often used to assess research findings, security protocols, or software code, helping to identify flaws and improve reliability.
