Data: Oil of the 21st Century
Data is the most valuable asset of any organisation in the modern age. And at the same time, it is also the most vulnerable asset. Modern businesses generate a vast amount of data, and much of it is confidential.
Over the years, staff have saved a lot of data on laptops and computers. This includes customer data, their passwords or other sensitive financial information. Some files may contain trade secrets. There are many other examples as well:
- Customer details
- Financial records
- Employee information
- System credentials
- Intellectual property
- Confidential emails and communications
End of Device ≠ End of Data
When these devices are finally no longer usable and should be recycled or donated, the data stored in them is still relevant and needs to be protected from unauthorized people. Otherwise, you risk data breaches, reputational damage, and legal consequences.
London businesses can destroy their data by partnering with reputable corporate recycling services that also offer hard disk destruction services or data destruction services.
The purpose of this blog is to help business owners understand the basic terminologies and their differences like data destruction, data sanitisation, data wiping, and degaussing that sound the same to non-technical minds. It will help them pick the exact service that they want.
Difficulty of Technical Jargon
In today’s era of unprecedented data generation, businesses need a proper strategy for end-of-life IT equipment disposal. Data security has to be a number one operational priority during phases like upgrading IT infrastructure, decommissioning old devices, or changing the office location.
UK businesses also need to comply with strict regulations. That includes laws like the Data Protection Act (2018) and GDPR. They mandate secure handling and destruction of personal and sensitive information.
What may make the situation challenging are the technical jargons that IT disposal and data destruction use frequently. Frequent use does not guarantee that people fully understand them.
Terms like data wiping, data sanitisation, and data degaussing are not the same in their nature. They can be strikingly different in process, cost, effectiveness, and the types of devices they are compatible with.
This article will give you a quick glimpse of what every term means so as a business owner you can make an informed decision about which one you need. You will need this information when you get in touch with a corporate IT recycling service to safely destroy your data.
Organisations must understand these terms for their IT disposal London projects.
Data Sanitisation Vs Data Destruction
Understanding these two basic categories can help you understand all the industry terminologies. All other terms fall under one of them.
Data Sanitisation: An Introduction
Data sanitisation is an irreversible process of making data inaccessible or non-readable without destroying the device. It may alter the data in a way that no one will ever be able to understand it. No forensic method, no matter how advanced, should have a potential to reconstruct it.
There are different methods used in the industry to sanitise the data. We will discuss them in the coming sections.
Data Destruction: An Introduction
Data destruction, unlike sanitisation, does not care about the storage device. This is the practice that actually destroys the storage devices, so data is lost in the dust forever. Devices are physically destroyed and are no longer functional.
There are different methods used in the industry to perform data destruction operations. We will discuss them in the coming sections.
Methods of Data Sanitisation
Here is how we normally sanitise the data.
1: Overwriting
Overwriting replaces the existing data with random data sets. These data sets are nothing but meaningless patterns of 0s and 1s. However, you need multiple passes to make data recovery nearly impossible. The method is suitable for hard drives, solid-state drives (SSDs), and other storage media.
The beauty of data sanitisation methods is keeping the devices still intact and usable. That makes it a much greener option than data destruction. You can not only use the device within your office but also resell it or even donate it.
Overwriting is a subset of data wiping. Data wiping is the name of making data gone or inaccessible using software-based methods.
Best when:
- You want to resell or reuse equipment
- Equipment is low in quantity
2: Cryptographic Erasure
It is a method that encrypts the data to make its access impossible. We first set a password on the data and then delete the password from the system. Now, no one can access the data. It is a great method when you have a large number of devices of devices to sanitise. You cannot let every device go through multiple passes of overwriting. That would consume a lot of time. The use of cryptographic erasure is common in cloud environments and SSDs.
Cryptographic erasure and overwriting are great options when you want to keep the hardware usable. Data sanitisation is a perfect strategy when your plan includes repurposing, reselling, or redeploying IT assets.
Best when:
- You have bulk equipment
- Most of them are SSDs
Methods of Data Destruction
These methods destroy the devices, which must be done in an environmentally friendly way. Look for certified corporate IT recycling services that adhere to industry standards to fulfil your corporate social responsibility. Data destruction is a part of the normal computer disposals process.
1: Degaussing
This method applies a high-powered magnetic field to disrupt the magnetic information on storage media. It is the most effective data destruction method, but it makes the device unusable, which is not good from a sustainability perspective.
The degaussing method applies a high-power magnetic field to disrupt the magnetic information on the storage media. It can permanently erase all data on the storage devices. Degaussing is great for backup tapes, floppy disks, and traditional HDDs.
Best when:
- You have old HDDs or magnetic tapes.
- You need very fast bulk destruction.
- Reuse is not a priority.
2: Physical Destruction
It refers to physically damaging a device to the point where data cannot be recovered. Devices are torn into tiny pieces with the help of industrial equipment. Some companies claim to tear hard drives into pieces as tiny as 2mm.
3: Incineration
Burning is another method of computer destruction. Incineration is the practice of burning the devices at high temperatures until they are damaged enough that data is permanently destroyed. Some industries use it for highly sensitive data.
Physical destruction and incineration methods are best when:
- The data is highly sensitive
- Reuse of devices is near to impossible.
Conclusion
All these methods serve a specific purpose, depending on the device type and the security level required. Picking the appropriate choice is essential, whether your priority is compliance, eco-friendly disposal, fast destruction, or maximum security. With data breaches on the rise, secure data destruction is no longer optional.
It is a fundamental part of responsible IT asset management that you can easily fulfil with the help of good corporate IT recycling services.
Computer IT Disposals can help you responsibly destroy the data with the technique that suits your unique business requirements.
