Times are changing and we have to learn new things all the time. People interested in privacy on the Internet have been faced with a flood of new acronyms and terms lately. Here comes a brief list of terminology that has remained fairly unknown for a long time, but suddenly become very central to how our cyber society is developing. Keep these in mind if you want to be privacy-savvy.
The best know signal intelligence system of the cold war era. Operated by the NSA and capable to store and analyze both data and telephone traffic globally. Today a legacy system.
FISA, Foreign Intelligence Surveillance Act
A US law that, together with other related laws and amendments, controls usage of non-US citizens’ communications for the benefit of US interests. Controls is however a misleading word as it pretty much boils down to carte blanche to spy on foreigners. This is of paramount importance for the whole Internet as most of the cloud services are run by American companies, and most users are foreigners.
FISC, FISA-Court, United States Foreign Intelligence Surveillance Court
A secret US court that is supposed to review and approve data gathering efforts under the FISA and related laws. Evil tongues call it a rubber stamp, but it has actually denied 11 requests out of a total of 33 949 during 1979-2012. (Some of those 11 were approved after modification.)
A court order to shut up about something.
GCHQ, Government Communications Headquarters
UK’s own NSA. Responsible for gathering info from Internet traffic for the needs of the UK government and military.
A former encrypted mail service run by Ladar Levinson. Became iconic in the fight for Internet privacy when closed down in August 2013. According to Ladar: “I have been forced to make a difficult decision: to become complicit in crimes against the American people or walk away from nearly ten years of hard work by shutting down Lavabit.” This smells NSL (see below) to high heaven.
NSA, National Security Agency
USA’s main signals intelligence agency. Operates globally to intercept and decode information. Recent reports indicate that NSA’s strategy largely seems to be to store as much information as possibly for further use, rather than picking targets and eavesdropping selectively. NSA is also a leader in cryptography and cryptanalysis, and is believed to have more supercomputer capacity than anyone else on this planet.
NSL, National security letter
An order from a US agency to hand over information or implement information gathering systems. These letters come with strict gag orders that even prevents the subject from revealing the existence of a NSL or seeking legal advice about it. Their legal status is controversial because of the broad gag orders that are in conflict with the 1st amendment. Anyone should keep the NSLs in mind when listening to top executives of Google, Facebook, Apple etc. who denies that NSA can tap into their systems.
Currently the best known of all the data gathering programs run by NSA. PRISM is apparently a database application that stores data from many sources.
SIGINT, Signals intelligence
Operations aiming to gather information by eavesdropping on communications and other signals or stored data. Involves the art of decoding or decrypting messages as well as gathering information by analyzing traffic patterns.
A system run by UK’s GCHQ that collects data in real time from internet and telephone communications.
Utah data center
A data center located in Bluffdale, Utah and operated by the NSA. The center is about to be finalized and believed to provide 3 – 12 Exabyte of storage data right now, more in the future as storage technology evolves. It has been said that five Exabyte is equivalent to all words ever spoken by humans since the dawn of time. This is outdated, but still interesting when trying to imagine how much an Exabyte really is. So what exactly is NSA going to do with all this storage?
A NSA system that gives analysts powerful tools to query for information about identified targets or suspicious patterns in larger datasets.
A person who makes crimes or other unethical activities known to a larger public, often by violating agreements or the law. A significant portion of what we know about SIGINT on the Internet has been revealed by whistleblowers.
Bruce Schneier: “First, be careful with names. PRISM is a specific NSA database, just a part of the overall NSA surveillance effort. The agency has been playing all sorts of games with names, dividing their efforts up and using many different code names in an attempt to disguise what they’re doing. It allows them to deny that a specific program is doing something, while conveniently omitting the fact that another program is doing the thing and the two programs are talking to each other. So I am less interested in what is in the specific PRISM database, and more what the NSA is doing overall with domestic surveillance.”
Very well said! Here you can find a more comprehensive list of NSA programs and codenames.
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
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?

Passwords are the keys to online accounts. A good password known only to account owners can ensure email, social media accounts, bank accounts, etc. stay accessible only to the person (or people) that need them. But a bad password will do little to prevent people from getting access to those accounts, and can expose you to serious security risks (such as identity theft). And sadly, many people continue to recycle easy to guess/crack passwords. A recent study conducted by researchers from Google attempted to nail down the most common pieces of advice and practices recommended by security researchers, and unsurprisingly, several of them had to do with passwords. And there were several gaps between what security experts recommend people do when creating passwords, and what actually happens. Here’s 3 expert tips to help you use passwords to keep your accounts safe and secure. Unique Passwords are Better than Strong Passwords One thing experts recommend doing is to choose a strong and unique password – advice many people hear but few actually follow. Chances are, if your password is on this computer science professor’s dress, it’s not keeping your accounts particularly secure. Many major online service providers automatically force you to choose a password that follows certain guidelines (such as length and character combinations), and even provide you feedback on the password’s strength. But security researchers such as F-Secure Security Advisor Sean Sullivan say that, while strong passwords are important, the value of choosing unique passwords is an equally important part of securing your account. Basically, using unique passwords means you shouldn’t recycle the same password for use with several different accounts, or even slight variations of the same word or phrase. Google likens that to having one key for all the doors in your house, as well as your car and office. Each service should get its own password. That way, one compromised account won’t give someone else the keys to everything you do online. A strong password will be long, use combinations of upper-case and lower-case letters, numbers, and symbols. The password should also be a term or phrase that is personal to you – and not a phrase or slogan familiar to the general public, or something people that know you could easily guess. But there are still many ways to compromise these passwords, as proven by The Great Politician Hack. So using unique passwords prevents criminals, spies, etc. from using one compromised password to access several different services. Sullivan says choosing strong and unique passwords for critical accounts – such as online banking, work related email or social media accounts, or cloud storage services containing personal documents – is a vital part of having good account security. Experts Use Password Managers for a Reason One study showed that the average Internet user has 26 different online accounts. Assuming you’re choosing unique passwords, and you fit the bill of an “average Internet user”, you’ll find yourself with a large number of passwords. You’ve now made your account so safe and secure that you can’t even use it! That’s why experts recommend using a password manager. Password managers can help people maintain strong account security by letting them choose strong and unique passwords for each account, and store them securely so that they’re centralized and accessible. Keeping 26 or more online accounts secure with strong and unique passwords known only to you is what password managers do to keep your data safe, which is why 73% of experts that took part in Google’s study use them, compared to just 24% of non-experts. Take Advantage of Additional Security Features Another great way to secure accounts is to activate two-factor authentication whenever it’s made available. Two-factor (or multi-factor) authentication essentially uses two different methods to verify the identity of a particular account holder. An example of this would be protecting your account with a password, but also having your phone number registered as a back-up, so any kind of password reset done on the account makes use of your phone to verify you are who you say you are. While the availability of this option may be limited, security experts recommend taking advantage of it whenever you can. You can find a list of some popular services that use two-factor authentication here, as well as some other great tips for using passwords to keep your online accounts secure.
