Home working: preparing your organisation and staff for WFH…again!

With the recent announcement (December 8) that businesses are once again being advised to encourage home-working amongst their workforce, we look at how you can ensure your organisation is prepared for an increase of WFH once more.

As part of managing the continuing Covid-19 situation, amidst the surge of the new Omicron variant, many organisations will once again be encouraging more of their staff to work from home. However, this presents new cyber security challenges that must be managed.

The guidance from the National Cyber Security Centre recommends steps to take if your organisation is introducing (or scaling up the amount of) home working.

For official information about Coronavirus, please refer to trusted resources such as the Public Health England or NHS websites.

For advice on helping your users to spot coronavirus scam emails, please refer to the NCSC guidance on dealing with suspicious messages.

Asking your staff to work from home...again!

Whilst working from home will not be new to many organisations and employees, Covid-19 has forced many organisations to consider home working on a greater scale, and for a longer period of time. You may have more people working from home than usual, and some of these may not have done it before.

Setting up new accounts and accesses

If you need to set up new accounts or accesses so your staff can work from home, you should set strong passwords for user accounts. Please refer to the NCSC guidance for system owners responsible for determining password policy. The NCSC strongly recommend you implement two-factor authentication (2FA) if available.

Preparing your staff for home working

Working from home can be daunting for people who haven't done it before, especially if it's a sudden decision. There are also practical considerations; staff who are used to sharing an office space will now be remote. Think about whether you need new services, or to just extend existing ones, so that teams can continue to collaborate. For, example you may want to consider services that provide chat rooms, video teleconferencing (VTC) and document sharing.

The NCSC guidance on implementing Software as a Service (SaaS) applications can help you choose and roll out a range of popular services. If you are already providing such services, you'll need to plan for a potentially large increase in users, and any new services you provide will also need to be supported.

Here are some general recommendations to support secure home working.

  • Remote users may need to use different software (or use familiar applications in a different way) compared to what they do when in the office. You should produce written guides for these features, and test that the software works as described.

  • Depending on the experience of your staff (and the applications you provide), you should consider producing a series of 'How do I?' guides so that your already stretched support team isn't overwhelmed with requests for help. For example, you might produce a 'How to log into and use an online collaboration tool' guide.

  • Remember, many of your staff are already stressed, so they're not in an ideal position to learn new technologies. In addition, they might not be able to ask an office workmate for help, as they normally might. You should check how staff are coping; not just in terms of how to use new technologies, but also how they are adapting to having to work in very different ways.

  • Staff are more likely to have their devices stolen (or lose them) when they are away from the office or home. Make sure devices encrypt data whilst at rest, which will protect data on the device if it is lost or stolen. Most modern devices have encryption built in, but encryption may still need to be turned on and configured.

  • Fortunately, the majority of devices include tools that can be used to remotely lock access to the device, erase the data stored on it, or retrieve a backup of this data. You can use mobile device management software to set up devices with a standard configuration.

  • Make sure staff know how to report any problems. This is especially important for security issues (see looking after devices below).

  • Your staff might feel more exposed to cyber threats when working outside the office environment, so now is a great time for them to work through the NCSC's Top Tips for Staff e-learning package.

Controlling access to corporate systems

Virtual Private Networks (VPNs) allow remote users to securely access your organisation's IT resources, such as email and file services. VPNs create an encrypted network connection that authenticates the user and/or device, and encrypts data in transit between the user and your services.

If you are already using a VPN, make sure it is fully patched. Additional licenses, capacity or bandwidth may be required if your organisation normally has a limited number of remote users.

If you've not used one before, please refer to the NCSC's VPN Guidance, which covers everything from choosing a VPN to the advice you give to your staff.

Helping staff to look after devices

Devices used for working outside an office environment are more vulnerable to theft and damage. Whether using their own device or the organisation's, encourage staff to lock their screens if left unattended, especially if there are children or housemates present. When the device is not being used, staff should keep it somewhere safe.

Make sure that staff know what to do if their device is lost or stolen, such as who to report it to. Encourage users (in a positive, blame-free manner) to report any losses as soon as possible. The early reporting of such losses may help minimise the risk to the data, and staff who fear reprisals are less likely to report promptly.

Ensure staff understand the importance of keeping software (and the devices themselves) up to date, and that they know how to do this.

Removable media

USB drives can contain lots of sensitive information, are easily misplaced, and when inserted into your IT systems can introduce malware. When USB drives and cards are openly shared, it becomes hard to track what they contain, where they've been, and who has used them. You can reduce the likelihood of infection by:

  • disabling removable media using MDM settings

  • using antivirus tools where appropriate

  • only allowing products supplied by the organisation to be used

  • protecting data at rest (encrypt) on removable media

You can also ask staff to transfer files using alternative means (such as by using corporate storage or collaboration tools), rather than via USB. For more information, refer to the NCSC's Removable media guidance.

Using personal rather than work devices

If you are permitting people to use their own devices to work remotely, please refer to the NCSC's Bring Your Own Device (BYOD) guidance.

Spotting email scams linked to the coronavirus

Cyber criminals are preying on fears of the coronavirus and sending 'phishing' emails that try and trick users into clicking on a bad link. Once clicked, the user is sent to a dodgy website which could download malware onto your computer, or steal passwords. The scams may claim to have a 'cure' for the virus, offer a financial reward, or be encouraging you to donate.

Like many phishing scams, these emails are preying on real-world concerns to try and trick people into doing the wrong thing. Please refer to our guidance on dealing with suspicious messages.
