According to the Personal Data Protection Commission (PDPC), data breaches are on the rise in the country. Singapore is a trendsetter in digital technology and businesses leverage the latest systems for data collection and analysis. But what happens to data you no longer need, or that’s in devices at the end of their lives?
Data sanitization comes in handy at the last stage of the information lifecycle management. This is a process to destroy data in storage devices permanently and make it irretrievable. Whatever your industry, data sanitization is essential to protect your organisation.
The most effective data sanitisation processes are cryptographic erasure using public-key cryptography, physical destruction, and data erasure. These data destruction methods meet stringent guidelines set in local and international data privacy laws.
Read on to find out more about data sanitization terminology, methods, information lifecycle management (ILM) and much more.
What Methods Do Not Achieve Data Sanitization?
Many businesses now use the latest data storage devices and systems. With the prominence of data in decision making, organisations leverage cutting-edge data tools to analyse collected data. The way you handle the data and data storage devices determines how secure the information is. Any flaws in your data management processes can lead to data loss. When your company’s data falls into the wrong hands, you become more vulnerable to attacks, financial losses, and legal trouble.
One way to guarantee complete safety of data is through data sanitization. This guarantees any storage hardware that might be disposed of doesn’t contain important data. The following are some ineffective data sanitization methods your organisation might be deploying:
Many organisations fall prey to hackers and other malicious elements because of poor data sanitization processes. Using any of these techniques might temporarily remove data from your files and folders. However, a data expert can still retrieve the data. The illegal access to such data can cause exposure of your company’s trade secrets, clients’ data, and other sensitive information. Hackers can also use the data to blackmail you for monetary gain.
Data Sanitisation Terminology
Data security is an evolving field with a lot of emerging terms. With the critical role that data plays in your business, it’s imperative to understand new terms in information lifecycle management. In relation to data sanitization, here’s some important terminology:
Information Lifecycle Management is the structured management of the flow of data in an information system from the point of data creation and initial storage to the moment it’s no longer needed and needs to be destroyed. Information lifecycle stages: The stages of in the management of data are:
Differentiating Between Information Lifecycle Management and Data Lifecycle Management
For the best data destruction practices, you need to differentiate between information lifecycle management and data lifecycle management. To illustrate the difference, consider a company where the policy is to delete all emails over 3MBs after 30 days. This is an example of data lifecycle management. There’s no consideration of the email contents or information.
On the other hand, information lifecycle management goes beyond general attributes such as size, age or type of file. In the case of the example above, the company policy considers the email content. The ILM technology used manages emails based on informational content of the data.
Another distinguishing factor between ILM and DLM is in the application. While data lifecycle management only describes data management, information lifecycle management can be used to describe both digital and physical information.
Stages of Data Security Lifecycle
Data security lifecycle includes the following phases:
Final Thoughts
Businesses now generate more data than ever before. Data is now the most valuable asset for any organization. While much of the focus in data security is on active data, there’s a huge risk of data loss at the end of its lifecycle. Data sanitization secures data in end-of-life devices and other assets. With the best data management service, you can choose the right method of data destruction to protect your business.
