Dumpster diving refers to the act of searching through a company's trash to find confidential or useful information that has not been properly disposed of. If a company discontinues its secure shredding service and employees fail to adhere to secure disposal protocols, sensitive documents could be easily accessible in the trash, leading to potential security breaches.
References:The risks associated with improper disposal of sensitive information, including dumpster diving, are highlighted in CompTIA IT Fundamentals security modules, which discuss various threats to physical and digital data security.
