Data is not just a valuable asset in today’s high-stakes, artificial intelligence-driven commercial climate; it is also crucial to organisational vision. It is, in fact, the essential component that keeps businesses running smoothly and promotes their success. Organisations rely significantly on data, therefore it’s critical to strike the appropriate balance when using it.
Data breaches, data leaks, and unauthorised access by hackers occur when this data is not properly cleaned and monitored. Organisations need to develop guidelines and put best practices for data deletion into action in order to protect themselves from these threats. Let’s examine the ten essential data erasure best practices that every company needs to follow in order to guarantee the safe and permanent removal of sensitive data.
Top Data Erasure Techniques for Companies to Protect Privacy
Policies and guidelines such as the EU-GDPR, CCPA, PIPEDA, and the DPDP Act in India mandate that corporate and public sector entities follow secure data erasure procedures when deleting private and sensitive data. See the list of recommended practices for data erasure below, which companies should implement in order to comply with the strict laws.
- Create a Policy for Data Retention and Destruction: Any organisation should ideally start by planning and implementing a data retention strategy that specifies how long necessary data must be kept on file and how soon it must be securely deleted. Safe and efficient data management starts with a clearly stated data deletion policy.
- Compile a List of All Data-Carrying Equipment: The organisation has to map out and see all of the places where data-bearing devices are located. It’s critical to understand what data your company has and where it’s kept before putting data erasure policies into place. A thorough inventory list of all IT assets, including both digital and physical records, must be made by IT managers. By ensuring that no device is overlooked for data wiping once the retention period has ended, this inventory list will help reduce the likelihood of data vulnerability.
- Identify the Erasure Process: Businesses need to choose between using an offshore or onsite data deletion procedure. Businesses that require a high degree of control might choose for on-site erasure, which allows them to keep a close eye on the procedure taking place on their property. The risk of data leaking during onsite deletion is quite low. Businesses must, however, confirm the legitimacy of the third-party vendor, audit their facilities, and authenticate their certification before outsourcing the data erasing procedure to them for data wiping.
- Employ Software with Certified Data Erasure: To ensure thorough and secure data removal from HDDs and SSDs in desktops, laptops, servers, and mobile devices, businesses of all sizes are advised to use professional data erasure software certified by international bodies, such as BitRaser, Wipe drive, Kill Disc, etc. Either on-site or off-site, specialised data-wiping software needs to be utilised for erasure. The worldwide software certifications contribute to building confidence in the program’s effectiveness in eradicating all data utilising global algorithms.
- Utilise safe data wiping techniques: The National Institute of Standards and Technology (NIST) suggests destroying outdated data and rendering it unrecoverable by employing secure erasing techniques such block erase, cryptographic erase, and repeatedly overwriting data with random patterns. Similarly, three methods—Clear, Purge, and Destruct—for sanitising data-bearing devices are listed in IEEE standard 2883-2022. To properly wipe data, organisations must employ internationally accepted data erasure standards and algorithms.
- Train Staff on Data Erasure: Employees should be made aware of the significance of data erasure and given a clear set of guidelines to follow when handling sensitive information and keeping an audit trail consistent. Businesses can avert the possible nightmare of data breaches brought on by ignorance by arming staff members with information.
- Check and Record the Erasure Procedure: Your company needs to be able to validate data erasure with the aid of tamper-proof erasure reports after completing the process. Complying with legal, regulatory, and compliance audit obligations requires confirming data deletion. It illustrates how successful the company’s data deletion procedure is. In order to avoid non-compliance penalties, firms must also maintain comprehensive records of the data erasure procedure, including the date, time, method, and responsible individuals.
- Perform Audits on a Regular Basis: Conduct regular audits as a preventative measure to make sure data deletion procedures are being followed correctly. The intention is to lessen the likelihood of compliance lapses, data breaches, and unwanted meddling with confidential company information. The Rising Threat to Consumer Data in the Cloud study from Apple states that 5,212 verified breaches resulted in the exposure of 1.1 billion personal records worldwide in 2021.
- Update Erasure Policies Frequently: Review your data-erasure policies frequently to ensure they remain current with emerging technologies and alterations in regulations.
- Keep an eye on legal requirements and designate a DPO: Keep yourself updated about local data protection rules and regulations, and make sure that the standards for data erasure are being followed. The employment of a data protection officer, who may closely supervise the collecting and processing of data across the company, is another recommendation made by the data privacy legislation. Your company may be subject to fines if it ignores the new legislation and rules or does not follow them.
Important Learning
Data attacks are only anticipated to rise in the fast-paced, data-centric business world in order to achieve financial or competitive advantages. Data erasure can be implemented as a preventative measure to keep data security and privacy safe. Businesses can simplify their data management strategy and protect their reputation and data integrity by putting the aforementioned data erasure best practices into effect.
