I. Access Control
The first step in the security protocol is I. Access Control, which involves verifying the identity of users attempting to enter a secure area or access sensitive information. This process typically begins with authentication, where users are required to provide valid login credentials such as usernames and passwords. Biometric scanners may also be used for added security. Once authenticated, users are granted access to specific areas or systems based on their clearance levels and roles within the organization. Access control measures ensure that only authorized personnel can view or manipulate sensitive data, thereby preventing unauthorized access and maintaining confidentiality.
