Best Practices To Stop Dumpster Diving in Cybersecurity?
Apply a Trash Management Plan
Implement a plan to efficiently manage your garbage & recycle bins as part of your Data Loss Prevention strategy. Garbage can be in two forms: Digital and physical.
Determine how to discard old or useless documents, notes, books, & hardware. The plan must also detail what information to keep & discard.
For example, if a client or employee is no longer with your business, it’s significant to correctly delete their data. In the case of physical trash, you can scrap or burn paperwork.
Practice Storage Media Deletion
Practice regular and steady storage media deletion. Get rid of DVDs & CDs or some other drives containing private identifiable information such as videos, photos, or some other sensitive information.
If you have PCs, laptops, or other hardware to abandon, dispose of them correctly & wipe all files and programs to stop future damages.
Enforce a Data Retention Policy
Enforce a data holding policy that governs & monitors how long information should be kept and disposed of when it’s no longer relevant. Moreover, make sure the policy encompasses the purpose of treating information.
Employees must always know how to handle, store, & discard business data in all its forms. . Furthermore, a certificate of destruction for sensitive data is also important.
Use a Shredder
Place protected shredder bins next to all trash cans within your work location. Don’t just tear & dump your paperwork in bins as attackers can effortlessly join them together and save information to plan a cyber-attack.
The shredder totally destroys documents with important information.
Carry out regular educational programs to teach employees about real information disposal and other attack stoppage strategies. Describe what your data retention policy entails & how they should abide by it.
Employees must never take printouts, photocopies, old computers, or some other company information house for disposal.

Audit trails of trash must be adopted, and private investigators can be hired to experience their proficiency in getting the information from the trash.
