Five tips for businesses and individuals for secure remote working by Paul Ducklin, Principal Research Scientist at Sophos.
Tips for businesses to drive secure remote working
Many Self-Service Portals (SSPs) allow users to choose between different levels of access, so they can safely connect up either a personal device (albeit with less access to fewer company systems than they’d get with a dedicated device), or a device that will be used only for company work. The three key things you want to be able to set up easily and correctly are: encryption, protection and patching.
If employees genuinely can’t do their job without access to server X or to system Y, then there’s no point in sending them off to work from home without access to X and Y. Make sure you have got your chosen remote access solution working reliably first – force it on yourself! – before expecting your users to adopt it.
Don’t just leave employees to their own devices (literally or figuratively). If you’ve set up automatic updating for them, make sure you also have a way to check that it’s working, and be prepared to spend time online helping them fix things if they go wrong. If their security software produces warnings that you know they will have seen, make sure you review those warnings too, and let them know what they mean and what you expect them to do about any issues that may arise.
If you haven’t already, set up an easily remembered email address where users can report security issues quickly and easily. Remember that a lot of cyberattacks succeed because cybercriminals try over and over again until one user makes an innocent mistake – so if the first person to see a new threat has somewhere to report it where they know they won’t be judged or criticised (or, worse still, ignored), they’ll end up helping everyone else.
Shadow IT is where non-IT staff find their own ways of solving technical problems, for convenience or speed. If you have a bunch of colleagues who are used to working together in the office, but who end up flung apart and unable to meet up, it’s quite likely that they might come up with their own ways of collaborating online – using tools they’ve never tried before. The first risk everyone thinks about in cases like this is, “What if they make a security blunder or leak data they shouldn’t?” But there’s another problem that lots of companies forget about, namely: what if, instead of being a security disaster, it’s a conspicuous success? A temporary solution put in place to deal with a public health issue might turn into a vibrant and important part of the company’s online presence
We’re living in tricky times, so try not to let matters of public health cause the sort of friction that gets in the way of doing cybersecurity properly!

Even if they promise news you are interested in, any information in the attachment will almost certainly be available from a more direct source, via a link of your own choosing. If you are genuinely interested to know the official Johns Hopkins coronavirus figures, find your own way to the real site. That will not only avoid malware or phishing attacks but also protect you from manipulated data and fake news.
“Enable macros” sounds innocent, and crooks often tell you that you have to do it in order for Word or Excel to display the file properly. Don’t do it! “Macro” is a jargon word that really means “an embedded program that can do almost anything, including downloading malware, installing new software and stealing files”.
