Encryption is extensively recognised as a key manner of enhancing information safety, and the EU’s General Data Protection Regulation (GDPR) is driving adoption – however not all companies discover it straightforward to undertake.
Research reveals that companies usually are not making use of widespread encryption instruments successfully to include the fallout and prices of information breaches and encryption continues to be thought-about tough to deploy and use, particularly by small to medium-sized enterprises (SMEs).
Any small enterprise adopting disk encryption or rolling it out extra extensively to spice up their information safety capabilities ought to take into account 5 key points, in keeping with Bernard Parsons, CEO of disk encryption agency Becrypt.
1. Ease of use
Above all else, Parsons believes small companies ought to search for merchandise which can be straightforward to make use of and simple and fast to put in.
“This is partly about reducing the time and expertise required to install products in the first place, but an important subsequent point is also total cost of ownership,” he mentioned.
If a product shouldn’t be straightforward to put in, Parsons mentioned it’s normally indicator that there’s a degree of complexity that may stay as a long-term enterprise overhead.
“The more complex a product is, the more complexity there is to manage, leading to higher levels of required expertise and the more potential for support issues to occur over time, driving up the product’s total cost of ownership for the organisation,” he mentioned.
2. Accessible assist
After ease of use, SMEs ought to take into account whether or not a possible encryption provider can provide good technical assist, mentioned Parsons.
“Even if you choose a product that is easy to use, which is going to reduce the amount of required technical support, you should still think about the potential for requiring support over the total life of the product,” he mentioned.
When companies are contemplating doing one thing barely in a different way in future, similar to encrypting new units which may be non-standard, similar to RAID servers, it will likely be helpful to have the ability to name somebody with enough experience, mentioned Parsons.
“The option of phone-based support is important – being able to jump onto a call in a reasonable amount of time and actually talk to an expert,” he mentioned. “Therefore, we would certainly recommend testing this process with a vendor or the partner before you go ahead and procure.”
3. Proof of encryption
Although encryption turns what would doubtlessly be an info loss into simply the lack of a bodily asset, defending the organisation’s info and addressing its liabilities, beneath rules such because the GDPR, there may be usually a requirement to show that units truly had been encrypted within the occasion of a loss, to keep away from among the reporting necessities inside these rules.
“Proving that a device loss is not an information loss and avoiding the need to undertake breach notification is something you want to be able to think about in advance,” mentioned Parsons.
For companies that deploy an encryption product that features centralised administration, that performance ought to already be there. But, mentioned Parsons, many small companies will select to deploy in a extra standalone configuration, with out the necessity to get up a central administration platform.
“With standalone installs, you should still ensure that that product has a reporting capability of some kind, such as online, allowing the encryption status of your estate of devices to be reported,” he mentioned.
4. Extendibility
Another key problem SMEs ought to take into account is whether or not encryption merchandise can be utilized throughout a number of working techniques, that are discovered even inside small enterprise IT environments.
“While firms may initially be looking at deploying encryption within an estate of Windows devices, in a year or two they may have other requirements, such as needing to manage encryption on Mac devices, or on smartphones and mobile devices within that same suite of products,” mentioned Parsons.
“Therefore, it is a good idea to look for vendors that have multi-platform offerings, helping to future-proof your technology choice. This will ensure that you are not tied to a vendor, but at least ensuring that your existing supplier is an option as your requirements grow.”
5. Best observe
Finally, Parsons mentioned there may be an growing regulatory requirement to reveal that organisations have gone by means of some technique of making certain that the know-how they’re utilizing represents finest observe.
“For example, GDPR explicitly references ‘state of the art’ technology,” he mentioned. “To fully ensure that you are managing liabilities, you need to evidence that you are not just adopting technology, but that it is appropriately ‘state of the art’.”
Achieving this degree of confidence may be accomplished solely by know-how that has third-party validation by means of product assurance or product certification, mentioned Parsons, for instance to supply impartial validation that the product is of an applicable high quality.
Although there may be quite a lot of widespread certification schemes related for encryption merchandise, such because the US Federal Information Processing Standard (FIPS) to make sure that algorithms have been appropriately applied, Parsons mentioned organisations must be cautious of adopting know-how simply because it has a FIPS certification.
“The majority of products use the same algorithms, such as the Advanced Encryption Standard (AES),” he mentioned, “and FIPS ensures that a third party has validated that the vendor has correctly implemented the algorithm. But suppliers can, and still do, implement products inappropriately, leaving vulnerabilities.”
A great instance of such vulnerabilities in encryption merchandise is inside stable state drives (SSDs), mentioned Parsons.
“Recent research from Radboud University in the Netherlands has highlighted vulnerabilities in not just one supplier, but a whole range of suppliers’ SSDs,” he mentioned. “The fundamental reason that they highlight is that it is actually not easy to implement encryption well, and it is easy to make mistakes. Vendors can take shortcuts, which means security researchers can then find resulting vulnerabilities. In this case, they were able to bypass the encryption within SSDs.”
For this cause, mentioned Parsons, organisations ought to as a substitute search for certification schemes which can be extra complete, such because the Commercial Product Assurance (CPA) scheme run by the UK’s National Cyber Security Centre (NCSC).
“CPA works alongside FIPS for validating algorithms, but it says more about the overall product quality and implementation, looking at the security architecture to make sure it has been designed and implemented in a sensible way,” he mentioned.
The CPA additionally appears to be like on the provider coding and construct requirements to cut back the chance of there being a vulnerability within the product. “The risk is never fully mitigated,” mentioned Parsons, “but it certainly goes down to a point that allows you to say that, as an organisation, you are adopting best practice.”
