If you bring your phone, tablet or laptop with you when you travel, there’s one thing to keep in mind: public WiFi networks are public.
“That open Wi-Fi connection opens the door for hackers,” writes NPR’s Steve Henn. “They can get in the middle of transactions between, say, you and your bank.”
Because you’re sharing the network with strangers, there’s the risk that someone is using readily available software that snoops on what you’re doing.
“It may feel private because you’re using your personal device, but it’s not,” our Security Advisor Sean Sullivan told us last year.
Sean advises against doing anything via public WiFi that you wouldn’t want an eavesdropper to know – including logging into accounts with passwords.
Before you hit the road make sure all your devices are backed up, your applications and operating system are patched and you’re running an updated security solution on any device you can.
You can try F-Secure SAFE on up to 3 devices for free for the next month.
Here are some more tips that will keep you secure wherever you may roam:
• Don’t let your device connect to public WiFi spots automatically.
• Delete out the WiFi access points you’ve used when you arrive home.
• Log out of all your apps you don’t need while traveling.
• Lock any device you’re your using with a code that can’t be guessed.
• Be aware of your surroundings and anyone who could be trying to peek over your shoulder.
• Use a unique, strong password for each account.
• For laptops, disable file sharing and turn on the firewall, setting it to block incoming connections.
• Use a VPN (virtual private network) like Freedome if possible, which secures your connection even on public WiFi.
• Use a travel router with a prepaid SIM card for your own personal WiFi network.
• At the very least, watch for the padlock and “https” in the address bar for any site with your personal information. If they’re not there, avoid the site.
• A good general rule: Assume anything you do over public WiFi is part of a public conversation.

"F-Secure is Top Rated, with three Advanced+ awards," AV-Comparatives writes in its new Summary Report. "We felt that its completely new user-interface design is very clear and easy to use, with excellent alerts." The Austrian-based non-profit tests products "for their ability to protect against real-world Internet threats, identify thousands of recent malicious programs, and provide protection without slowing down the PC. Additionally, optional tests checked how well the products could remove malware from an infected PC, block new and unknown threats, and protect the user against phishing attacks." The report examines Internet Security's ease of use from the moment it's installed. The product's main features, warnings, search services, browser customization and scanning are scrutinized. "We were impressed with the design of F-Secure’s new single-window interface," they write. "The very clean home page has status, help and scan functions, while all other features are easily accessed by clicking the Tools tab." We're proud to put our work and commitment to provide you the best protection possible to the test. We're even prouder when we end up being Top Rated. [Image by Tomislav Kovacevic | via Flickr]
January 7th was a sad day. The Charlie Hebdo shooting in Paris was both an attack on free speech and fuel for more aggression against Muslims. And controversially also fuel for even more attacks against free speech. The western society’s relation to free speech is very complicated nowadays. Officially it is still valued as a fundamental right. But it is also seen as a threat, even if politicians are very keen to masquerade free speech reductions as necessary security improvements. British PM Cameron’s recent debacle is an excellent example. In his opinion, there must not be any form of communication that the authorities can’t listen in to, which would mean restrictions on encryption. Non-digital metaphors are usually a good way to explain things like this. This is as smart as banning helmets because they make it harder to recognize criminals riding motorcycles. French president Francois Hollande wanted to join the party and proposed a law making internet providers responsible for users' content in their services. The idea was to make companies like Facebook and Twitter monitor all communication and call Paris as soon as someone talks terrorism. This goes even further than Cameron as it actually would force companies to do the police’s work. But should the phone company also be held responsible if it turns out that a terrorist has been allowed to place calls? And maybe even send mail delivered by the postal service? Hollande did of course not include those as they would help people understand how crazy the idea is. Anything can be misused for criminal purposes. But trying to make providers of things responsible is just madness and hurts the whole society and economy. The important point here is naturally that freedom of speech is a much broader concept than what Charlie Hebdo utilizes. The caricatures express our freedom to communicate publicly without censorship. But there is also another dimension of free speech. Everybody has the right to choose whom they communicate with and whom a message is intended for. This is not just about secrecy and privacy, it is really about being free to exchange opinions without worrying about them being used against you later by some third party. This dimension of free speech would of course not exist in Cameron’s ideal society. So no Cameron and Hollande, you are definitively not Charlie! It’s sad that the great “Je Suis Charlie” -movement has become a symbol for both freedom of speech and hypocrisy. Didn’t you really see anything wrong in first marching in support of Charlie Hebdo in Paris, and then immediately attack freedom of speech yourself? It takes courage to be a leader and balance between security and freedom. Today we really need leaders like Benjamin Franklin, who had guts and said things like “Freedom of speech is a principal pillar of a free government; when this support is taken away, the constitution of a free society is dissolved, and tyranny is erected on its ruins.” and “Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.” Safe surfing, Micke Image by Markus Winkler @ Flickr under CC BY-SA 2.0 via Wikimedia Commons Benjamin Franklin quotes from wikiquote.org
