When your business is done with any data, you probably just right click on it and press “delete,” thinking it’s been properly erased from your device.
However, all deleting does is hide your data; it’s not synonymous with wiping the data, which means a complete removal.
If you’re an organization that deals with client and partner data, then it’s important you understand and follow standards and regulations to ensure you erase data properly.
In today’s data-driven world, businesses of all sizes collect and handle large amounts of sensitive information, from customer and partner details to proprietary trade secrets. As data breaches and cyber attacks continue to make headlines, it’s more important than ever to safeguard this valuable data and protect it from falling into the wrong hands. While many companies focus on implementing security measures like firewalls and encryption, there’s another critical aspect of data protection that’s often overlooked: proper data erasure. When you dispose of or replace devices that store sensitive data, simply deleting files or reformatting the drives isn’t enough to ensure that the data is irretrievable. In this article, we’ll take a closer look at the DoD 5220.22-m standard and why it’s essential to follow proper data erasure guidelines for your business.
When it comes to disposing of data, it’s easy to assume that deleting it from your device is enough. However, that’s far from the truth. Simply deleting data doesn’t actually remove it from your device; it merely hides it from view. The data can still be recovered with the right tools and expertise.
This is where properly erasing data comes into play. Proper data erasure ensures that your sensitive information is completely wiped from your device, preventing it from falling into the wrong hands. This is especially important for organizations that handle sensitive client and partner data.
Without proper data erasure, your organization risks serious consequences, such as loss of reputation, financial penalties, and legal liability. It’s crucial to understand and follow data erasure standards and regulations to ensure the complete removal of your data.
In the next section, we’ll discuss one such standard that is widely adopted in various industries – the DoD standard.

What Is the DoD Standard?
The DoD standard is also known as the DoD 5220.22-m standard. It first came about in 1995 and was originally created for the US military (hence “DoD,” or “Department of Defense”). This dictated how data was erased from hard drives so that information was never compromised.
The standard is composed of a series of steps that must be taken to properly sanitize data from hard drives. The recommended steps are as follows:
- Overwrite with binary zeroes: The first step involves overwriting the entire hard drive with binary zeroes. This ensures that the original data is erased and that the data cannot be recovered.
- Overwrite with binary ones: The second step is to overwrite the entire hard drive with binary ones. This helps to ensure that any residual data that might have been missed in the first step is overwritten and eliminated.
- Overwrite with a random bit pattern: In the third step, a random bit pattern is used to overwrite the entire hard drive. This step further ensures that the original data is erased and that the data cannot be recovered.
- Verify the final overwrite: The final step involves verifying that the last overwrite was successful. This helps to ensure that all data has been erased, and that there are no traces of the original data left on the hard drive.
By following these steps, the DoD 5220.22-m Standard ensures that data is properly erased from hard drives and cannot be recovered by any means.
Why Does the DoD 5220.22-m Standard Matter?
The DoD 5220.22-m standard matters because it provides a clear and effective way to completely erase data from devices. It is essential to erase data completely to prevent it from falling into the wrong hands and being used for malicious purposes. If data is not properly erased, it can be recovered using various methods and techniques, even after it has been deleted.
This is particularly important when getting rid of devices, as old devices leaving your place of business can pose a significant risk to the security of your data. If sensitive information falls into the wrong hands, it can lead to serious consequences such as data breaches, identity theft, and financial losses.
Therefore, following the DoD 5220.22-m standard can help organizations ensure that their data is properly sanitized and cannot be recovered by unauthorized individuals. Failing to follow the standard can lead to serious risks and consequences for your business.
As you can see, the DoD 5220.22-m standard matters because you want to erase data completely when you’re done with it. Otherwise, you risk it falling into the wrong hands.
This is especially important if you’re getting rid of devices and replacing them with new ones. Once the old devices leave your place of business, then it can be very easy for other parties to retrieve data on your hard drives.
The Future of the DoD Wiping Standard
The DoD 5220.22-m standard has been the go-to method for data erasure for many years, but with the advent of solid-state drives (SSDs), it has become less effective. The problem lies in the fact that SSDs store data differently than traditional hard disk drives (HDDs), and as a result, they require a different approach to properly erase data.
To address this issue, the National Institute of Standards and Technology (NIST) developed the NIST 800-88 guidelines for media sanitation. These guidelines provide a more comprehensive approach to data erasure, taking into account the unique characteristics of SSDs.
While the NIST 800-88 guidelines are not a replacement for the DoD 5220.22-m standard, they provide a more up-to-date and effective approach to data erasure. As such, it is important to evaluate different standards and methods for data erasure, and to ensure that industry-standard guidelines are followed to properly erase data.
In addition to following guidelines, it is also recommended to combine different methods with physical destruction of data for optimal results. This ensures that all traces of data are completely eradicated, preventing any chance of it falling into the wrong hands.
Overall, the future of data erasure lies in staying up-to-date with the latest standards and methods, and ensuring that all data is properly erased before getting rid of devices.
Using the standard with solid-state drives (SSDs)
As technology evolves, so too must the methods used to erase data. While the DoD 5220.22-m standard has been the go-to for data erasure for many years, it has become outdated due to the widespread use of solid-state drives (SSDs). These drives use different methods of data storage than traditional hard drives, which render the DoD standard irrelevant.
NIST 800-88 guidelines and their relevance to data erasure
To address this problem, a new set of guidelines has emerged: the NIST 800-88. This standard provides guidelines for media sanitation that can be used across various devices, including solid-state drives. While the NIST 800-88 doesn’t offer certifications, it is widely used as a benchmark for media sanitation, including by the U.S. government.
Following industry-standard guidelines for data erasure
Whether you’re using traditional hard drives or SSDs, it’s crucial to follow industry-standard guidelines for data erasure. By doing so, you can ensure that your data is completely erased and can’t be recovered by unauthorized parties. It’s essential to take this step seriously, particularly if you deal with sensitive information, such as client or partner data.
In short, while the DoD 5220.22-m standard has been a reliable benchmark for data erasure for many years, it’s important to adapt to new technologies. By following the NIST 800-88 guidelines, you can ensure that your data is erased securely and prevent it from falling into the wrong hands.
Make Sure You Properly Erase Your Data
It’s important to evaluate different standards and methods for data erasure to ensure that you’re following the most effective guidelines for your organization’s needs. While the DoD 5220.22-m standard was widely used in the past, the industry has now shifted towards the NIST 800-88 guidelines due to the increasing use of solid-state drives (SSDs).
Different methods with physical destruction of data for optimal results
To ensure the most effective data erasure, it may be best to combine different methods with the physical destruction of data. This could include following industry-standard guidelines like NIST 800-88, using specialized data wiping software, and physically destroying the hard drives themselves. By combining these methods, you can better protect any sensitive information that your organization deals with and prevent it from falling into the wrong hands.
Properly Erasing Data and Following Industry-Standard Guidelines
The importance of properly erasing data cannot be overstated. Organizations and individuals must take data privacy and security seriously to avoid risks of data breaches, identity theft, and other cybercrimes.
Following industry-standard guidelines such as the DoD 5220.22-m and NIST 800-88 is crucial to ensure data is completely erased from all storage devices. As technology continues to advance, it’s essential to stay up-to-date on the latest data erasure standards and methods.
