Sophos provides 7 cybersecurity tips for a carefree summer

Oosterhout, 19 July 2022 – The summer holidays have officially started and from the beginning of July, holidaymakers travel for one or more weeks to destinations far from home. Most likely, most of them have laptop, mobile phone, tablet, portable speakers, chargers and similar equipment in their luggage. And while many of them (perhaps too much) trust the good advice they have received over the years about the importance of working safely from home, Sophos is happy to list some more tips that will be helpful this holiday.

  1. Ask your employer for permission to take your laptop with you on vacation

If the answer is “no”, then it is better to leave it at home. If the employer says “yes”, there is a good chance that the employer will inquire into your destination and give you appropriate advice and conditions.

  1. Make a backup before your vacation

When traveling, employees are more likely to lose or damage their phone or laptop than at home or in the office. Because you have made a reliable backup of all your data before you go on holiday, you also have a small amount of digital data with you when, for example, you cross a border.

“The only backup you will ever regret is the one you did not make,” said Paul Ducklin, Principal Research Scientist at Sophos.

  1. Encrypt your phone and computer data

It is best to choose a long lock code (at least 10 digits), so not a code that is easy to remember and therefore easy to crack. To remember better, it is wise to use this code occasionally a few days before departure.

  1. Prepare border controls

Many countries that carry out border controls reserve the right to unlock electronic devices as a condition of access. In addition, a number of countries require not only a home address and phone number, but also email addresses and social media accounts. Sophos recommends that you check the country’s entry requirements before departure and whether or not to bring electronic devices.

  1. Be careful when using public Wi-Fi networks

The dangers of public Wi-Fi are often exaggerated and sometimes largely unavoidable, provided employees stick to properly encrypted applications and websites with URLs beginning with HTTPS: //, an abbreviation for “secure HTTP”. In some countries, however, it may be necessary to install a special digital certificate in order to access services (eg for “regulatory or security reasons”). This means that surfing the internet during and after the trip could definitely be spied on.

For these countries, Sophos recommends purchasing a local SIM card with a prepaid data plan for the entire duration of the trip. Please note: most countries require their telecommunications providers to provide them with legitimate eavesdropping methods so that a prepaid phone is not completely anonymous.

  1. Avoid using computers at airports and hotels

Sophos strongly advises against this, unless there is absolutely no other option. The problem with these types of “terminals” is and will be that the companies that operate these computers, the technicians who maintain them, and everyone else who has used terminals before you are not very secure.

  1. Beware of hidden cameras in hotel rooms and holiday homes

Unfortunately, hidden cameras in those places are a reality. Sometimes they are quite easy to spot if you carefully tidy the room. But sometimes they are so small that they can be hidden in almost anything, and they are not always visible on the property’s public Wi-Fi network.
