Who does not enjoy a holiday? Time away from work is a chance to rest, but many of us still take a tablet, laptop or smartphone with us. A few simple habits can help ensure that a pleasant trip does not become a cybersecurity incident.
Make backups
Regular backups can save important files if a phone, tablet or laptop is stolen, damaged or lost. This is especially important during a holiday, when devices are exposed to more risks than usual. Use cloud storage or an external drive, and consider encrypting the backup before uploading it. If you use a cloud provider, apply limited trust and review who can access the data.
Keep an eye on your smartphone
Your phone may contain banking apps, email, photos and active social-media sessions. Do not lend it to strangers or share it casually with people you know. If someone asks to make a call, make the call yourself and verify the number first. For extra protection, ask your operator to block premium-rate calls.
Secure the device
Use a strong password, PIN or biometric lock and enable automatic screen locking. Avoid simple patterns that someone can observe and reproduce. Full-device encryption adds another layer of protection if the device is lost or stolen.
Avoid public Wi-Fi
Disable automatic connection to known Wi-Fi networks when travelling. Fake hotspots may use names similar to those of hotels, cafes, airports or stations. A criminal connected to the same network may intercept data such as email traffic or banking credentials. If you need internet access on a laptop, tether it to your phone’s mobile connection instead.
Update software
Update your operating system, browser, messenger and other applications before you leave. Unused applications should be removed rather than left unpatched, because they can become an entry point for malware.
Think before you post holiday photos
Sharing your current location tells criminals that you are away from home and gives them useful information about your routine. Consider posting photos after you return and restrict their visibility to people you trust.
Your cybersecurity is primarily in your hands. Follow basic cyber-hygiene rules, stay alert and do not let a dream holiday turn into a nightmare.
