Step-by-step guide for secure disposal of devices with sensitive data (LGPD + technical standards)

Introduction

Safe disposal of devices containing sensitive data is essential for privacy protection and compliance with the General Data Protection Law (LGPD) and specific technical standards. This article presents a technical step-by-step guide to ensure the correct and secure destruction of these devices, minimizing leakage risks and meeting applicable legal requirements.

1. Identification of Devices with Sensitive Data

The first step consists of accurately identifying all electronic devices that store personal and sensitive data, such as hard drives, SSD units, pen drives, smartphones, and other storage equipment. Correct identification allows selecting appropriate disposal and sanitization methods according to the criticality of the information.

2. Assessment of Applicable Legislation and Technical Standards

The procedure must be aligned with LGPD (Law No. 13,709/2018), which establishes guidelines for the secure handling of personal data, preserving the privacy of data subjects. In addition, international technical standards recommended, such as those published by the United States National Institute of Standards and Technology (NIST), including the NIST SP 800-88 Rev.1, which deals with media sanitization, should be observed.

3. Selection of the Appropriate Sanitization Method

Sanitization of devices can be carried out through physical means, logical means, or total destruction, depending on the confidentiality level of the data. Physical methods involve mechanical, chemical, or thermal destruction; logical methods involve secure erasure through cryptographic formatting software or multiple overwrites. It is recommended to opt for certified techniques that ensure data is unrecoverable.

4. Procedure for Sanitizing Storage Devices

For the safe disposal of hard drives and other media, internationally tested and recognized steps must be followed, with the process recorded for auditing. It is essential to register the method used and issue a destruction certificate, according to best practices recommended by hard drive sanitization. Such documents support LGPD compliance and guarantee disposal traceability.

5. Logistics and Secure Collection

After sanitization or destruction, the devices must be delivered for environmentally correct disposal. The reverse logistics process must ensure integrity and prevent any risk of recovery or unauthorized reuse. The specialized electronic waste collection service follows strict protocols, contributes to environmental care, and provides proof of proper disposal, as outlined in electronic waste collection.

6. Documentation and Compliance

The entire process must be documented, including equipment inventory, sanitization reports, destruction certificates, and disposal proof. This is essential for auditing and legal compliance. The absence of such documentation may result in fines and other penalties provided under the LGPD and related legislation.

7. Training and Qualification of Professionals

Control and security also depend on the ongoing training of those involved in the disposal process. Up-to-date technical training ensures the correct application of procedures and alignment with current legislation.

Conclusion

Implementing a rigorous safe disposal process for devices with sensitive data, based on the LGPD and technical standards such as NIST SP 800-88, is fundamental to protect personal information, reduce legal risks, and ensure environmentally responsible disposal. The use of specialized services and proper documentation are pillars for compliance and security.
