How to keep your kids safe online this summer

It’s a fact of life: once school is out,  kids spend more time online. You may try to schedule when they can and can’t use the PC and use solutions like Parental Control to prevent some trouble. But simply limiting access to Facebook and YouTube and the rest of the online world is a limited strategy. The fact is whether it’s on a desktop, a laptop or a smartphone, most kids—or at least, most teenagers—can get online whenever they want.

That’s why we suggest spending a few minutes explaining the risks of cybercrime and online predators to your family. Of course, your kids will probably brush you off  by repeating “I know, Mom (or Dad)” over and over, as if you’re trying to discuss the birds and the bees. So don’t go in unprepared. Check out these five quick tips to keep your kids and your PC safe until school resumes in fall.

1. Repeat the mantra “Links are not your friends”
Cybercriminals are aware that millions of people Facebook have plenty of time to kill. That’s why they’re spreading their scams with links described as “The Sexiest Video EVER” or “You’ll never believe this LOL.” When you’re bored and a link like that appears on a Facebook wall posted by a friend, it takes incredible will power not to click it. So repeat this mantra: If a link looks too good to be true, it is. Of course, this won’t always work. That’s why you should bookmark F-Secure’s free Browsing Protection. If your son or daughter feels they must click, have them check it out first. What else do they have to do? It’s summer.

2. Keep up with the updates
If you don’t keep your system software up to date, you risk inviting predators into your PC. Monthly updates for Windows, Adobe Reader, iTunes, and other applications are essential for your online safety.  F-Secure’s Health Check makes this time-consuming process easy. Run it once a month and save yourself some major headaches.

3. Tell your kids that you will handle installing software
Once you’ve run Health Check and made sure you’re protected, there’s no need for your kids to install any random software that pops up. So tell your child that it’s mom or dad’s job to install new software, no matter what pops up.  Once you’re home and had a nice summer beverage, check out the software. Google it to see if it’s a legitimate and then decide if it’s worth your hard drive space. Nothing ruins a nice summer afternoon like getting tricked into installing malware on your PC.

4. Make clear what information your kids should not share
Most kids know more about Facebook than you’d ever want to. They know how to add and erase apps or how to block this user and not that one. But they may not know what they should NOT share. Tell your kids that they should never private information—email addresses, phone numbers, home addresses—on any social network. They should also avoid posting information about their schedule, especially vacations or details about when their parents will be home or not. Your kids need to know that no matter how private their settings tell them they are, anything they post on a social network should be considered as public as the front page of a newspaper—if they know what that is.

5. Let them know that you are watching
You need to know which social networks your children are on. If you have the time and patience, it’s a good idea to start a profile on the site and become their friend or follower. It doesn’t take long, maybe five minutes per site. You can’t watch your child every minute. But if they get the sense that you could be watching, it can only help them think before they click or post.

Cheers,

Only 10% protected – Interesting study on travelers’ security habits

Kaisu who is working for us is also studying tourism. Her paper on knowledge of and behavior related to information security amongst young travelers was released in May, and is very interesting reading. The world is getting smaller. We travel more and more, and now we can stay online even when travelling. Using IT-services in unknown environments does however introduce new security risks. Kaisu wanted to find out how aware young travelers are of those risks, and what they do to mitigate them. The study contains many interesting facts. Practically all, 95,7%, are carrying a smartphone when travelling. One third is carrying a laptop and one in four a tablet. The most commonly used apps and services are taking pictures, using social networks, communication apps and e-mail, which all are used by about 90% of the travelers. Surfing the web follows close behind at 72%. But I’m not going to repeat it all here. The full story is in the paper. What I find most interesting is however what the report doesn’t state. Everybody is carrying a smartphone and snapping pictures, using social media, surfing the web and communicating. Doesn’t sound too exotic, right? That’s what we do in our everyday life too, not just when travelling. The study does unfortunately not examine the participants’ behavior at home. But I dare to assume that it is quite similar. And I find that to be one of the most valuable findings. Traveling is no longer preventing us from using IT pretty much as we do in our everyday life. I remember when I was a kid long, long ago. This was even before invention of the cellphone. There used to be announcements on the radio in the summer: “Mr. and Mrs. Müller from Germany traveling by car in Lapland. Please contact your son Hans urgently.” Sounds really weird for us who have Messenger, WhatsApp, Facebook, Twitter, Snapchat and Skype installed on our smartphones. There was a time when travelling meant taking a break in your social life. Not anymore. Our social life is today to an increasing extent handled through electronic services. And those services goes with us when travelling, as Kaisu’s study shows. So you have access to the same messaging channels no matter where you are on this small planet. But they all require a data connection, and this is often the main challenge. There are basically two ways to get the data flowing when abroad. You can use data roaming through the cellphone’s ordinary data connection. But that is often too expensive to be feasible, so WiFi offers a good and cheap alternative. Hunting for free WiFi has probably taken the top place on the list of travelers’ concerns, leaving pickpockets and getting burnt in the sun behind. Another conclusion from Kaisu’s study is that travelers have overcome this obstacle, either with data roaming or WiFi. The high usage rates for common services is a clear indication of that. But how do they protect themselves when connecting to exotic networks? About 10% are using a VPN and about 20% say they avoid public WiFi. That leaves us with over 70% who are doing something else, or doing nothing. Some of them are using data roaming, but I’m afraid most of them just use whatever WiFi is available, either ignoring the risks or being totally unaware. That’s not too smart. Connecting to a malicious WiFi network can expose you to eavesdropping, malware attacks, phishing and a handful other nasty tricks. It’s amazing that only 10% of the respondents have found the simple and obvious solution, a VPN. It stands for Virtual Private Network and creates a protected “tunnel” for your data through the potentially harmful free networks. Sounds too nerdy? No, it’s really easy. Just check out Freedome. It’s the super-simple way to be among the smart 10%.   Safe surfing, Micke   PS. I recently let go of my old beloved Nokia Lumia. Why? Mainly because I couldn’t use Freedome on it, and I really want the freedom it gives me while abroad.   Image by Moyan Brenn

Forget the personality tests – Ask Facebook instead (Poll)

It’s amazing how advertising can power huge companies. Google has over 57 000 employees and some 66 billion US dollars in revenue. And Facebook with 12 billion and 10 000 employees. These two giants are the best know providers of ad-financed services on the net. And modern advertising is targeted, which means that they must know what the users want to see. Which means that they must know you. Let’s take a closer look at Facebook. We have already written about their advertising preferences and I have been following my data for some time. Part of the data used to target ads is input by yourself, age, gender, hometown, movies you seen etc. But Facebook also analyzes what you do, both in Facebook and on other sites, to find out what you like. It’s obvious how the tracking works inside Facebook itself. Their servers just simply record what links you click. Tracking in the rest of the net is more sinister, it’s described in this earlier post. Your activity record is analyzed and you are assigned to classes of interest, called “Your Ad Preferences” by Facebook. Advertisers can then select classes they want to target, and the ad may be shown to you based on these classes. You can view and manage the list using a page that is fairly well hidden deep in Facebook’s menus. Let’s check your preferences in moment, but first some thoughts about this. Advertising may be annoying, but it is the engine that drives so many “free” services nowadays. So I’m not going to blame Facebook for being ad-financed. I’m not going to blame them for doing targeted ads either. That can in theory be a good thing, you see more relevant ads that potentially can be of value to you. But any targeted ad scheme must be based on data collection, and this is the tricky part. Can we trust Facebook et al. to handle these quite extensive personal profiles and not misuse them for other purposes? It’s also nice that Facebook is somewhat open about this and let you view “Your Ad Preferences” (Note. Not available in all countries.). But that name is really misleading. The name should be “Facebook’s Ad Preferences for You”. Yes, you can view and delete classes, but that gives you a false sense of control. Facebook keeps analyzing what you do and deleted classes will reappear shortly. I made a full clean-up a couple of months ago, but now I have no less than 210 classes of interest again! This is really amazing if you take into account that I block tracking outside of Facebook, so those activities are not contributing. And I have a principle of not clicking ads in any on-line media, including Facebook. And liking commercial pages in a very restrictive manner. But the thing is that Facebook has realized that people dislike ads. “Suggested posts” or “Sponsored posts” are in fact masqueraded ads and any interaction with them will record your interest in the classes they represent. I have to admit that I do click this kind of content regularly. And where did that suicide thing come from? No, I’m fine. I’m not going to jump off a bridge and I’m not worried about any of my dearests’ mental health. I have not interacted with any kind of Facebook content related to suicide. Except that I can’t know that for sure. Facebook tries to give an open and honest image of itself when presenting its Ad Preferences settings and the possibilities to manage them. But this rosy picture is not the full truth. The inner workings of Facebook advertising is in reality a very complex secret system. When you interact with something on Facebook, you have no way of knowing how it affects your profile. Something I have clicked was apparently associated with suicides even if I had no clue about it. Ok, time to take the Facebook personality test. Let’s see what kind of person they think you are. Follow these instructions: Go to Facebook and locate an ad, a “sponsored post” or a “suggested post”. These items should have a cross or a down-arrow in the upper right corner. Click it. Select “Why am I seeing this?” from the pop-up menu. This screen contains some interesting info but proceed to “Manage your ad preferences”. Review the list and come back here to tell us what you think of it. Delete the inappropriate classes. Deleting all may reduce the number of ads you see.   So let’s see what people think about this test’s accuracy:   [polldaddy poll=9023953]   So using Facebook’s Ad Preferences as a personality test may be entertaining, but not very accurate after all. You should probably look elsewhere for a real test. The catch is that you can select what test to take, but not how others collect data about you. Someone else may rely on this test when evaluating you. You have actually granted Facebook the right to share this data with basically anyone. Remember this clause in the agreement that you read and approved before signing up? “We transfer information to vendors, service providers, and other partners who globally support our business, such as providing technical infrastructure services, analyzing how our Services are used, measuring the effectiveness of ads and services, providing customer service, facilitating payments, or conducting academic research and surveys.” You did read it before signing, didn’t you?   Safe surfing, Micke   Image: Screenshot from facebook.com

Is it OK to cheat on the AshleyMadison cheaters? (Poll)

The user register of AshleyMadison has been hacked. You don’t know what that is? Well, that’s perfectly fine. It’s a dating site for people who want to cheat on their spouses. Many dislike this site for moral reasons, but there is apparently a demand for it. The Canadian site has some 37 million users globally! Some user data has already been leaked out and the hackers, calling themselves Impact Team, have announced that they will leak the rest unless the site shuts down. So this hack could contribute to many, many divorces and a lot of personal problems! "We will release all customer records, profiles with all the customers' sexual fantasies, nude pictures and conversations and matching credit card transactions, real names and addresses." The Impact Team This is one hack in a long row, not the first and certainly not the last site hack where user data is leaked. But it is still remarkable because of the site’s sensitive nature. Think about it. What kind of information do you store in web portals and what bad could happen if that data leaks out? If you are cheating on your spouse, then that is probably one the most precious secrets you have. Disclosure of it could have devastating effects on your marriage, and maybe on your whole life. Millions of users have put their faith in AshleyMadison’s hands and trusted them with this precious secret. AshleyMadison didn’t misuse the data deliberately, but they failed to protect it properly. So it’s not that far-fetched to say that they cheated on the cheaters. What makes the AshleyMadison hack even worse is the site’s commercial nature. Users typically pay with a credit card issued in their own name. They can appear anonymously to their peers, but their true identities are known to the site owner, and stored in the database. So any leaked information can be linked reliably to real people. The sad thing is that the possibility of a leak probably never even crossed the mind of these 37 million users. And this is really the moral of the story. Always think twice before storing sensitive information in a data system. You must trust the operator of the system to not misuse your data, but also to have the skills, motivation and resources to protect it properly. And you have very poor abilities to really verify how trustworthy a site is. This is not easy! Refraining from using a site is naturally the ultimate protection. But we can’t stop using the net altogether. We must take some risks, but let’s at least think about it and reflect over what a compromised site could mean. This hack is really interesting in another way too. AshleyMadison is a highly controversial site as cheating is in conflict with our society’s traditional moral norms. The hack is no doubt a criminal act, but some people still applaud it. They think the cheaters just got what they deserved. What do you think? Is it right when someone takes the law in his own hands to fight immorality? Or should the law be strictly obeyed even in cases like this? Can this illegal hacking be justified with moral and ethical arguments? [polldaddy poll=8989656]       Micke   Image: Screenshot from www.ashleymadison.com
