Wiki Article

In the current era of information security, protecting sensitive information involves more than just installing antivirus software. Physical media, such as backup tapes, optical discs, and USB sticks, often contain significant volumes of personal information. When these items are no longer needed, improper disposal may result in costly compliance violations.
The Importance of Secure Destruction

Numerous businesses mistakenly believe that simply deleting files is enough . Nevertheless, malicious actors can easily retrieve information from partially destroyed devices. To maintain total security, you must follow proven protocols for the disposal of physical hardware.

Blu-ray discs record information within a physical substrate which is prone to manual destruction. Even so, surface damage might not secure every file.

Specialized Shredders: Employ a device designed for optical media. These units cut the disc into cross-cut pieces rather than simple strips .

Grinding: This involves grinding off the information-bearing surface from the plastic. Without the coating, the info no longer exists.

Handling Solid-State Media

USB sticks are particularly difficult as they utilize solid-state (SSD) technology . Traditional degaussing does not work on these devices .

Micro-shredding: Since the data chips are tiny, they must be shredded into extremely small particles to guarantee the silicon is pulverized.

Physical Crushing: Using a heavy-duty press to smash the flash controller and chips is another layer of security .
