1. Know what you’re getting into
Facebook is a business. It exists to take your online activity and turn it into revenue. Facebook will always be free. But there is a cost. You’re paying by being exposed to advertising and allowing limited disclosure of your online activity.
So here’s a short version: basically everything you post, every person you friend, every group you join will be made public to your “friends”, “friends of your friends” or “everyone”—depending on your privacy settings.
To you this may be simple. You assume that everything you’ve posted could be available to the whole world. Others are still learning. People have lost their jobs as a result of things they’ve posted on Facebook. And when this happens, the newly unemployed person will usually claim that s/he thought that the post was private.
And, more importantly, you have to trust yourself to share the right things.
On Facebook, you are exposing your private life in ways you may not even realize. 79% of companies review an applicant’s online information (which is completely illegal in Finland but acceptable in most of the world). Your financial future could depend on how well your profile and your photos and friends list represent you. So think before you post—always.
2. Secure your PC
What does 500,000,000 people on one website look like? To cybercriminals, it looks like a gigantic, unsecured goldmine.
Online gangs and scammers are working twenty-four hours a day to exploit the trust we have for our online friends. Updated Internet security is a must before you use Facebook or any social site. In addition, you have to make certain that your PC is updated with the most recent application system software, which can be time-consuming. F-Secure’s free Health Check makes that easy.
3. Use a unique, strong password
‘Password’ is not a good password. Neither is ‘123456’ or your pet’s name or your name any information that is available publicly on your Facebook profile.
Creating a strong, complex password that you can remember is the key to keeping strangers out of your account. Here’s a simple password system we recommend. You should also use different passwords for your all of your various accounts, especially your email accounts, to keep one hack from becoming a total nightmare.
For extra protection, never let browser remember your password, and lock your PC when you step away from it—especially if you’re living with young children and/or parents and/or anyone, really.
4. Filter your friends
Facebook works overtime to connect you with as many people possible. When you first join, the site combs through your email account to suggest as many people as possible. Then as you use the site it will suggest more email contacts. Email someone new and Facebook will suggest that you become friends.
Run out of contacts, you’ll see friends of friends, brands you might like, your ex.
It’s a strange social dynamic. When see the person’s picture, it feels like this person wants to be your friend. But who knows? All you can be sure of is that Facebook wants you to be friends.
So ask yourself this: Does everyone you email need to be your Facebook friend?
Some people have found that their best friends in the real world make lousy Facebook friends. There are a lot of people who can find you who may not like reconnecting with. According to a recent survey, 70% of Facebook users avoided becoming friends with their bosses.
Maybe you want to limit Facebook to your friends and family and leave professional connections to Twitter and LinkedIn. There’s no perfect formula, but it’s important to have some filter, some limit on what you share with whom. How do you say no when someone you don’t want to offend makes a friend request? Facebook makes this easy. You can just ‘ignore’ the request. That’s a nice way to frame it!
Want to stop Facebook from combing through your email contacts? You can remove your contacts by clicking here. But if you’re using a Facebook app on your phone, first you’ll have to disable the Facebook synchronization feature on your phone.
Want to stop Facebook from suggesting you as a friend to others? Go to “Privacy Settings” click on “Settings” for “Basic Directory Information”. When you get there, set “Search for me on Facebook” to “Friends Only”.
Always remember this: If anyone solicits you directly about money, assume it’s a scam. Ignore and defriend that profile immediately. An easy way to defriend someone is to go to their profile and scroll down the left column until you find “Remove from Friends”.
5. Click carefully
The biggest dangers on Facebook are the links that appear on your wall. With one bad click, you could end up on a site that attempts to serve you malware or scam you using phishing tactics. One, bad ‘like’ and you could end up spamming all of your friends. That’s why you have to remember that links are not your friends.
The most popular Facebook scams involve gift cards and hilarious videos and diet advice. So far most attacks on the site have been more annoying than harmful. But without vigilance, you can be sure that vicious scams and malware are heading your way.
The best antidote to bad links is Internet security with browsing protection. You can double-check any link before you click it by copying it (right-click on it in Windows) and pasting it into F-Secure’s free Browsing Protection.
Prevention is your best cure. Realize the more sensational or strange or generic a link is, the more likely it is to be malicious. Again, links are not your friends. Apply the same caution you’ve learned to use when you’re checking email to checking Facebook. And just because your friend or family linked something, doesn’t mean you have to click on it.
6. Don’t rely on Facebook to protect your privacy
The whole point of Facebook is to “connect and share with the people in your life.” But there’s a point, for nearly everyone, where all the connecting and sharing can be too much—especially as your information becomes increasingly available to people who aren’t necessarily “in your life.”
So whenever you use Facebook, you have to ask yourself two things: Who do I want to see what I’m doing? And how would I feel if the whole world saw this?
There’s no technical tool to stop your friends from sharing your information. But Facebook does offer you the tools to control who sees your activity. That’s why you need to get to know your privacy settings.
Start at “Account”> “Privacy Settings”. Then click on “Settings” for “Basic Directory Information” . This is where you decide who can find you and what they’ll see when they do.
You get to decide. How easy do you want to make it to find you on Facebook? Which is more important to you: privacy or connection.
If you’re more interested in connection, select “Everyone” for the top three settings “Search for me on Facebook”, “Send me a friend request” and “Send me a message”. Then consider making all the other settings “Friends Only”. This will encourage people to become your friend, and it gives you more power over your information.
Next you can click back to “Privacy Settings” and set how you share on Facebook.
You can go with the preset options or customize each category individually.
Your safest bet is “Friends Only.” You may want to want to open your activity to “Friends of Friends”; however, there is certain information that you should not make available to “Everyone”. This includes your birthday, your email address and IM, your phone number and address, political and religious beliefs and your family and relationships.
Why? All of this information may be public somewhere else, like a phone book, but you’re simply making too much identifiable information public in one easily accessible place. There may not be enough there for true identity theft, but you are giving a stranger enough information to pose as you online convincingly, which could be a problem if some potential employer or date is checking out your online presence.
You may also want to uncheck the box that says “Let friends of people tagged in my photos and posts see them.” This way you won’t unintentionally draw attention to an image one of your friends may not want others to see.
If you’re very interested in your privacy, you should continue and edit your Application and Website Settings.
Here you should do two things. 1) Remove any applications you aren’t using. 2) Click on “Turn off all platform applications”. Then you can select which applications you don’t ever want to show up on your wall ever again. That’s right. You can say goodbye to FarmVille forever, if you want to.
You can also turn off all platform applications, which will keep your friends from automatically sharing your information with the applications they’re using. Not a bad idea.
Next you can click on “Game and application activity”. Click “Customize” and select “Only Me” to keep all of your Game and application activity to yourself, which is a good idea if you’re friends with people (read: co-workers) who may judge how you spend your time.
After that, take a look at “Info accessible through your friends”. Here you’ll see all the information that is available to the applications your friends decide to use. That’s right, your friends share all this information automatically with the applications they use.
Once you see that screen, you may want to go back to “Turn off all platform applications”. Why not turn it off until you have a good reason to turn it on?
So what does Instant Personalization do? It shares your information with three Facebook partner sites: Docs, Yelp and Pandora. Could more partners be added? Yes. Could you just opt out of one or two? Yes. Just click on Docs, Yelp or Pandora and then click on “Block Application.”
Again, unless you know you want to share information with these sites, it’s a good idea to opt out for now.
If you made it this far, you will be rewarded. We are now at, perhaps, the most important Facebook privacy setting: “Public Search”.
You probably heard how recently the information of over 100 million Facebook users was made available for download. All of that information was public before a security researcher took it and turned it into one downloadable file. Those 100 million Facebook users probably had enabled public search.
This is where get to decide if the whole world can find your Facebook profile and information. With one click, your profile could become the top result of a Google search for your name. If you want to avoid disclosure of your information to the world, you may want to start by limiting who can search for you. I recommend that you do not click the box to “Enable public search”.
So those are the tools Facebook gives you to protect your information. They’re complex, and that’s probably on purpose. Facebook is not shy about encouraging it’s users to share and share and share. That’s why you have to remember that Facebook (and your friends) can’t share anything you don’t post to the site.
So be careful not to post anything that can be used against you. This includes travel plans and itineraries, complaints about bosses, co-workers and customers, company secrets, threats… Has anyone actually had a home robbed after posting plans on Facebook? Yes, indeed.
There are a million things you shouldn’t post. And you are the only person who can decide what you SHOULD share with Facebook and the world. So choose wisely.
Bonus tip: Use Facebook’s one true security feature
Facebook’s one true security feature is simple but powerful. Facebook will inform you anytime any new device accesses your account. That means if some PC or smartphone you’ve never used before logs into your account, Facebook will email you.
To turn this feature on, go to “Account Settings”. Then select “Account Security”.
Just click “Yes ” and then “Submit”.
Now, what do you do if you find out that someone beside you accessed your account? Change your password immediately. On the “Account Settings” page find “Password” and click “change”.
OK. That’s all I know about making Facebook safer a place for you and your friends. For ongoing tips you can follow F-Secure on Facebook. Do you have any tips to add?
For this year's World Day against Cyber Censorship, F-Secure is giving away free subscriptions for our one-button Freedome app. You can use the key qsf257 to get a free 3-month subscription to Freedome! Freedom of expression is an important issue for everyone. Developments over the past year have highlighted how sensitive the matter is. It transcends national and cultural borders, yet these borders shape the issue differently for people across the globe. It belongs to us all, but it means different things to different people. Reporters without Borders launched the World Day against Cyber Censorship in 2008. Its intent is to raise awareness that our rights to say what we really think are not something to take for granted. Free speech is a dynamic concept that constantly grows and contracts in the face of developments that threaten its growth. While the Internet has given many people across the globe a powerful new voice, there are always threats mobilizing against this invaluable resource. The World Day against Cyber Censorship draws attention to this struggle. Last year Reporters without Borders compiled a list of what they call “Enemies of the Internet” as part of the annual event. If you look through it you’ll notice a diverse list of government agencies from nations across the world. Many of the events that highlight the fragility of our digital freedoms are attributable to these institutions, such as the Gemalto hack that saw the encryption keys to millions of phone calls stolen by the NSA and its fellow conspirators. And in some cases surveillance is just the beginning, as once these institutions identify their targets they can escalate their actions to include oppression. Hong Kong protestors saw this when local pro-democracy websites became infected with malware. Turkish people saw this during the Twitter crackdown. Drawing attention to these agencies as “enemies” of the Internet places the struggle within a larger dichotomy – enemies and allies. Even if it is a bit of a cliché or oversimplification of the conflict, it points out that people still have an opportunity to mobilize and assert their rights. And nobody is alone in this fight - we all have enemies and allies in this struggle. Having said all of this, World Day against Cyber Censorship isn't all about doom-and-gloom. Reporters without Borders is working to circumvent a number of websites blocked by governments. The Electronic Frontier Foundation continues to work to inform, educate, and represent the voices crying out for a free and open Internet. And F-Secure wants to help by making privacy and security solutions easy and accessible for people all over the world. Just get your trial version of the app and then use the key when it asks for your subscription number. Freedome gives you a one-button app that lets you encrypt your communications, disable trackers, and even change your virtual location. Check out this blog post for more information about the app. It's first come first serve, so don't miss this chance to take control of your digital freedom!
This year’s Mobile World Congress (MWC) is coming up next week. The annual Barcelona-based tech expo features the latest news in mobile technologies. One of the biggest issues of the past year has enticed our own digital freedom fighter Mikko Hypponen to participate in the event. Hypponen, a well-known advocate of digital freedom, has been defending the Internet and its users from digital threats for almost 25 years. He’s appearing at this year’s MWC on Monday, March 2 for a conference session called “Ensuring User-Centred Privacy in a Connected World”. The panel will discuss and debate different ways to ensure privacy doesn’t become a thing of the past. While Hypponen sees today’s technologies as having immeasurable benefits for us all, he’s become an outspoken critic of what he sees as what’s “going wrong in the online world”. He’s spoken prominently about a range of these issues in the past year, and been interviewed on topics as diverse as new malware and cybersecurity threats, mass surveillance and digital privacy, and the potential abuses of emerging technologies (such as the Internet of Things). The session will feature Hypponen and five other panelists. But, since the event is open to public discussion on Twitter under the #MWC15PRIV hashtag, you can contribute to the conversation. Here’s three talking points to help you get started: Security in a mobile world A recent story broken by The Intercept describes how the American and British governments hacked Gemalto, the largest SIM card manufacturer in the world. In doing so, they obtained the encryption keys that secure mobile phone calls across the globe. You can read a recent blog post about it here if you’re interested in more information about how this event might shape the discussion. Keeping safe online It recently came to light that an adware program called “Superfish” contains a security flaw that allows hackers to impersonate shopping, banking, or other websites. These “man-in-the-middle” attacks can be quite serious and trick people into sharing personal data with criminals. The incident highlights the importance of making sure people can trust their devices. And the fact that Superfish comes pre-installed on notebooks from the world’s largest PC manufacturer makes it worth discussing sooner rather than later. Privacy and the Internet of Things Samsung recently warned people to be aware when discussing personal information in front of their Smart TVs. You can get the details from this blog post, but basically the Smart TVs voice activation technology can apparently listen to what people are saying and even share the information with third parties. As more devices become “smart”, will we have to become smarter about what we say and do around them? The session is scheduled to run from 16:00 – 17:30 (CET), so don’t miss this chance to join the fight for digital freedom at the MWC. [Image by Hubert Burda Media | Flickr]
Ordinary people here in Finland have been confronted with yet another cybersecurity acronym lately, DoS. And this does not mean that retro-minded people are converting back to the pre-Windows operating system MS-DOS that we used in the eighties. Today DoS stands for Denial of Service. This case started on New Year’s Eve when customers of the OP-Pohjola bank experienced problems withdrawing cash from ATMs and accessing the on-line bank. The problems have now continued with varying severity for almost a week. What happens behind the scene is that someone is controlling a large number of computers. All these computers are instructed to bombard the target system with network traffic. This creates an overload situation that prevents ordinary customers from accessing the system. It’s like a massive cyber traffic jam. The involved computers are probably ordinary home computes infected with malware. Modern malware is versatile and can be used for varying purposes, like stealing your credit card number or participating in DoS-attacks like this. But what does this mean for me, the ordinary computer user? First, you are not at risk even if a system you use is the victim of a DoS-attack. The attack cannot harm your computer even if you try to access the system during the attack. Your data in the target system is usually safe too. The attack prevents people from accessing the system but the attackers don’t get access to data in the system. So inability to use the system is really the only harm for you. Well, that’s almost true. What if your computer is infected and participates in the attack? That would use your computer resources and slow down your Internet connection, not to speak about all the other dangers of having malware on your system. Keeping the device clean is a combination of common sense when surfing and opening attachments, and having a decent protection program installed. So you can participate in fighting DoS-attacks by caring for your own cyber security. But why? Who’s behind attacks like this and what’s the motive? Kids having fun and criminals extorting companies for money are probably the most common motives right now. Sometimes DoS-victims also accuse their competitors for the attack. But cases like this does always raise interesting questions about how vulnerable our cyber society is. There has been a lot of talk about cyber war. Cyber espionage is already reality, but cyber war is still sci-fi. This kind of DoS-attack does however give us a glimpse of what future cyber war might look like. We haven’t really seen any nations trying to knock out another county’s networks. But when it happens, it will probably look like this in greater scale. Computer-based services will be unavailable and even radio, TV, electricity and other critical services could be affected. So a short attack on a single bank is more like an annoyance for the customers. But a prolonged attack would already create sever problems, both for the target company and its customers. Not to talk about nation-wide attacks. Cyber war might be sci-fi today, but it is a future threat that need to be taken seriously. Safe surfing, Micke Image by Andreas Kaltenbrunner.
