Final answer:
The security training is aiming to prevent 'tailgating', where unauthorized access is obtained by following someone with proper clearance. This directive underscores the importance of preventing security breaches that can occur due to human error or negligence.
Step-by-step explanation:
The module in the security awareness course is attempting to mitigate a type of security failure known as 'tailgating' or 'piggybacking'. This occurs when an unauthorized person gains access to a restricted area by following someone with legitimate access. By not allowing employees to hold the door open for others, the module enforces a principle of individual accountability and ensures that each person is vetted through the badge access security system. This procedure is important as human error or negligence can lead to severe security breaches, similar to the one experienced by Target in 2013, where security personnel did not correctly interpret signals of a breach. Research, such as the study conducted by Bruno & Abrahão (2012), shows that cognitive overload can lead to more errors, exemplifying why stringent security practices are crucial for preventing breaches and maintaining secure environments.
