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?
Every time you go online, your personal privacy is at risk – it’s as simple as that. Whether you’re creating an account on a website, shopping, or just browsing, information like your email, IP address and browsing history are potential targets for interested parties. All too often, that information is sold on or sometimes even stolen without you even knowing it. And the threats to our online privacy and security are evolving. Fast. As F-Secure’s Online Protection Service Lead, Christine Bejerasco’s job is to make life online safer and more secure. “We’re basically online defenders. And when your job is to create solutions that help protect people, the criminals and attackers you’re protecting them against always step up their game. So it’s like an arms race. They come up with new ways of attacking users and our job is to outsmart them and defend our users,” Christine says. Sounds pretty dramatic, right? Well that’s because it is. While it used to be that the biggest threat to your online privacy was spam and viruses, the risks of today and tomorrow are potentially way more serious. “Right now we’re in the middle of different waves of ransomware. That’s basically malware that turns people’s files into formats they can’t use. We’ve already seen cases of companies and individual people having their systems and files hijacked for ransom. It’s serious stuff and in many cases very sad. If your online assets aren’t protected right now you should kind of feel like you’re going to bed at night with your front door not only unlocked but wide open.” Christine and her team of 11 online security superheroes (eight full-time members and three super-talented interns) are on the case in Helsinki. Here’s more on Christine and her work in her own words: Where are you from? The Philippines Where do you live and work? I live in Espoo and work at F-Secure in Ruoholahti, Helsinki. Describe your job in 160 characters or less? Online guardian who strives to give F-Secure users a worry-free online experience. One word that best describes your work? Engaging How long is a typical work day for you? There is no typical workday. It ranges from 6 – 13 hours, depending on what’s happening. What sparked your interest in online security? At the start it was just a job. As a computer science graduate, I was just looking for a job where I could do something related to my field. And then when I joined a software security company in the Philippines, I was introduced to this world of online threats and it’s really hard to leave all the excitement behind. So I’ve stayed in the industry ever since. Craziest story you’ve ever heard about online protection breach? Ashley Madison. Some people thought it was just a funny story, but it had pretty serious consequences for some of the people on that list. Does it frustrate you that so many people don’t care about protecting their online privacy? Yeah, it definitely does. But you grow to understand that people don’t value things until they lose it. It’s like insurance. You don’t think about it until something bad happens and then you care. What’s your greatest work achievement? Shaping the online protection service in the Labs from its starting stages to where we are today. What’s your idea of happiness? Road trips and a bottle of really good beer. Which (non-work-related) talent would you most like to have? Hmmm… tough. Maybe, stock-market prediction skills? What are your favorite apps? Things Stumbleupon What blogs do you like? Security blogs (F-Secure Security blog of course and others – too many to list.) Self-Help Blogs (Zen Habits, Marc and Angel, etc.) Who do you admire most? I admire quite a few people for different reasons. Warren Buffett for his intensity, simplicity and generosity. Mikko Hyppönen for his idealism and undying dedication to the online security fight. And Mother Theresa for embodying the true meaning of how being alive is like being in school for your soul. Do you ever, ever go online without protection? Not with systems associated to me personally, or with someone else. But of course, when we are analyzing online threats, then yes.

When news broke that Facebook was at least temporarily using users physical location to suggest real world connections, a strategy that has been employed by the NSA, the backlash was sharp. It wasn't difficult to imagine scenarios when identities could be inadvertently and uncomfortably revealed through group therapy, 12-step meetings or secretive political movements. The world's most popular social network quickly said it would not continue what it called a small-scale test nor roll the feature on a wider scale in the future. But Facebook is still using your location data for other purposes, Fusion's Kashmir Hill reports: We do know that Facebook is using smartphone location for other things, such as tracking which stores you go to and geotargeting you with ads, but the social network now says it’s not using smartphone location to identify people you’ve been physically proximate to. Hill notes that using location to match users up, thus acting as a tool to reveal the identity of nearby strangers, might violate Facebook's agreement with the Federal Trade Commission . So you should expect that your location -- like everything you do on Facebook -- is being used to turn you into a better product for its advertisers. That's the cost of using a "free" site but you can limit your exposure a bit by turning off location services for Facebook on your phone. Here's very simple instructions for turning off location services on your Facebook and Facebook Messenger apps on your Android of iOS device. Do you mind if Facebook uses your location to suggest new friends? Let us know in the comments. [Image by Lwp Kommunikáció | Flickr]
The Sony hack of late 2014 sent shock waves through Hollywood that rippled out into the rest of the world for months. The ironic hack of the dubious surveillance software company Hacking Team last summer showed no one is immune to a data breach - not even a company that specializes in breaking into systems. After a big hack, some of the first questions asked are how the attacker got in, and whether it could have been prevented. But today we're asking a different question: whether, once the attacker was already in the network, the breach could have been detected. And stopped. Here's why: Advanced attacks like the ones that hit Sony and Hacking Team are carried out by highly skilled attackers who specifically target a certain organization. Preventive measures block the great majority of threats out there, but advanced attackers know how to get around a company's defenses. The better preventive security a company has in place, the harder it will be to get in…but the most highly skilled, highly motivated attackers will still find a way in somehow. That's where detection comes in. Thinking like an attacker If an attacker does get through a company's defensive walls, it's critical to be able detect their presence as early as possible, to limit the damage they can do. There has been no official confirmation of when Sony's actual breach first took place, but some reports say the company had been breached for a year before the attackers froze up Sony's systems and began leaking volumes of juicy info about the studio's inner workings. That's a long time for someone to be roaming around in a network, harvesting data. So how does one detect an attacker inside a network? By thinking like an attacker. And thinking like an attacker requires having a thorough knowledge of how attackers work, to be able to spot their telltale traces and distinguish them from legitimate users. Advanced or APT (Advanced Persistent Threat) attacks differ depending on the situation and the goals of the attacker, but in general their attacks tend to follow a pattern. Once they've chosen a target company and performed reconnaissance to find out more about the company and how to best compromise it, their attacks generally cover the following phases: 1. Gain a foothold. The first step is to infect a machine within the organization. This is typically done by exploiting software vulnerabilities on servers or endpoints, or by using social engineering tactics such as phishing, spear-phishing, watering holes, or man-in-the-middle attacks. 2. Achieve persistence. The initial step must also perform some action that lets the attacker access the system later at will. This means a persistent component that creates a backdoor the attacker can re-enter through later. 3. Perform network reconnaissance. Gather information about the initial compromised system and the whole network to figure out where and how to advance in the network. 4. Lateral movement. Gain access to further systems as needed, depending on what the goal of the attack is. Steps 2-4 are then repeated as needed to gain access to the target data or system. 5. Collect target data. Identify and collect files, credentials, emails, and other forms of intercepted communications. 6. Exfiltrate target data. Copy data to the attackers via network. Steps 5 and 6 can also happen in small increments over time. In some cases these steps are augmented with sabotaging data or systems. 7. Cover tracks. Evidence of what was done and how it was done is easily erased by deleting and modifying logs and file access times. This can happen throughout the attack, not just at the end. For each phase, there are various tactics, techniques and procedures attackers use to accomplish the task as covertly as possible. Combined with an awareness and visibility of what is happening throughout the network, knowledge of these tools and techniques is what will enable companies to detect attackers in their networks and stop them in their tracks. Following the signs Sony may have been breached for a year, but signs of the attack were there all along. Perhaps these signs just weren't being watched for - or perhaps they were missed. The attackers tried to cover their tracks (step 7) with two specific tools that forged logs and file access and creation times - tools that could have been detected as being suspicious. These tools were used throughout the attack, not just at the end, so detection would have happened well before all the damage was done, saving Sony and its executives much embarrassment, difficult PR, lost productivity, and untold millions of dollars. In the case of Hacking Team, the hacker known as Phineas Fisher used a network scanner called nmap, a common network scanning tool, to gather information about the organization’s internal network and figure out how to advance the attack (step 3). Nmap activity on a company internal network should be flagged as a suspicious activity. For moving inside the network, step 4, he used methods based on the built-in Windows management framework, PowerShell, and the well-known tool psexec from SysInternals. These techniques could also potentially have been picked up on from the way they were used that would differ from a legitimate user. These are just a few examples of how a knowledge of how attackers work can be used to detect and stop them. In practice, F-Secure does this with a new service we've just launched called Rapid Detection Service. The service uses a combination of human and machine intelligence to monitor what's going on inside a company network and detect suspicious behavior. Our promise is that once we've detected a breach, we'll alert the company within 30 minutes. They'll find out about it first from us, not from the headlines. One F-Secure analyst sums it up nicely: "The goal is to make it impossible for an attacker to wiggle his way from an initial breach to his eventual goal." After all, breaches do happen. The next step, then, is to be prepared. Photo: Getty Images
