Move Your Certificates Away from SHA1

Certificates and PKI using SHA-1 are being deprecated

Andrew Walman

18/02/2016

​SHA-1 is the most commonly used hash function for certificates on the internet, and many internal root certificate servers. If your in-house certificate authority has been around since Windows 2003, it's likely it too uses the now insecure SHA-1. Since 2013, Microsoft have been deprecating use of SHA1 certificates within Windows, and from 1st January 2017, all supported versions of Windows will not accept any SHA-1 certificates. Payment processors have already announced they won't deal with SHA-1 from the summer too.

A Certificate with SHA-2

The certificate shown above is using the SHA384 signature algorithm, and so is it's root certificate - ensuring it will be accepted by all browsers without warnings through 2017.

At Fuse, we can help you transtition your certificate servers to the latest standards, ensuring your certificates use stronger encryption without breaking your existing systems and preventing access. We can also assist with installing the new certificates onto devices such as VPN gateways, web servers, laptops and phones, and with code/email signing and encryption certificates for files and backups. At the same time, we can harden your Windows Server TLS/SSL protocols so they only support newer protocols and ciphers. You can engage us within the context of a PKI project, or simply on a time and materials/consultancy basis. Either we'll ensure your infrastucture remains secure and compliant in a critical year for PKI.

‘We’d love you to stick around’. But stick around where?3728<p class="lead">Here at Fuse Collaboration Services both our personal and professional email inboxes are receiving a steady flow of emails from companies asking us to stay on their mailing lists. This is the most obvious and public aspect of the new GDPR that is currently being implemented.</p><p>There are a couple of positive side-effects from these new regulations, not least that by forcing you to opt in to mailing lists to make sure you are only receiving what you want to receive a company will really know how engaged you are, making your email address all the more valuable when it comes to marketing.</p><p>Companies have been responding to the GDPR changes by re-working their data management policies, but how much time is being put into how these policies can be enacted day-to-day, especially away from the aforementioned marketing email lists?</p><p>For example, if you have written a policy that says that emails are going to be stored for one year before deletion, how are you going to store them away from an active email server (thereby reducing the burden on a day-to-day server), or keep hold of them once a member of staff leaves? Or what happens if data is accidentally deleted by a member of staff?</p><p>Furthermore, data security is made all the more important as more and more companies opt for a flexible working approach where their staff can work from remote locations, such as home or (dare we say it) a high street coffee chain with its free Wi-Fi access.</p><p>Domestic or public internet access networks are unlikely to have the same levels of security as a company's, which makes it all the more important that any data transfer between a central hub and remote laptop is encrypted and has the latest security.</p><p>Chris Evans of Computer Weekly has highlighted <a href="https&#58;//www.computerweekly.com/feature/GDPR-brings-serious-implications-for-data-storage" target="_blank"> <span style="text-decoration&#58;underline;">five areas</span></a>&#160;which will impact the day-to-day work of the data storage manager under GDPR, including&#58;</p><ul><li>encryption; </li><li>detailed application-to-storage mapping;</li><li>security and audit; </li><li>validation of test and development requirements;</li><li>and collaborating closely with colleagues.</li></ul><p>Ultimately, you need to be able to give all your customers, clients, stakeholders and staff the confidence that their data and documents are stored securely, but also in a way that allows you to respond to data requests quickly and efficiently without having to wade through a mound of irrelevant information.</p><p>You also need to have the peace of mind that any deleted information can be recovered within your policy timetables, whether they be one year, five years, or longer than that.</p><p>There is also a danger that you could be sucked into a one-size-fits-all approach using policy and storage templates that have been designed for organisations that are in a different sector or are of a vastly different size to your own.</p><p>Fuse's data back-up and storage solutions tick all of the boxes you need to have that peace of mind to concentrate on your main business, namely growing as a company, while also being tailored to your specific needs.</p><p>Fuse uses a mixture of cloud-based packages to meet your requirements and allow your staff to access their relevant information <em>securely </em>regardless of where they are working. Our solutions are also easy to monitor by your in-house IT team, so that in the unlikely event of a data breach it can be identified, resolved and reported quickly.</p><div class="well well-lg"><p class="lead">Give us a call on 01604 797979 and we can have a chat about how you can make sure your data policy matches your day-to-day operations and requirements.</p></div> | Chris Wearmouth | 693A30232E777C6675736563735C632E776561726D6F757468 i:0#.w|fusecs\c.wearmouth16/05/2018 23:00:002018-05-16T23:00:00ZData security and rentention in a cloud based infrastructureData security in a cloud based infrastructure14/06/2018 09:56:102550htmlFalseaspx
