I’m sure we’ve all heard about MSN and Yahoo! Messenger, right? They can be useful, but the setup can be quite time consuming for those who need to use it just once or twice—and the privacy statements are a real bother. For example, we must provide our real details. You could use Fake Name Generator, but if you get caught, you will have your account suspended. I don’t have a law degree, but to my understanding the United States recently passed legislation that gives the authorities the power to charge people for providing false information to websites that require you to use real details.This is why I don’t recommend the big name instant messengers above. Others big name ones that require real details are, but not limited to the following:
Did you know the government is watching our Skype conversations? Personally, I have nothing wrong with that because it is more about catching the bad guys. However, it can be a little creepy, and potentially embarrassing.
Do you want to remain anonymous when using this chat room? I suggest installing TOR and setting it up to use the hidden service located here. This also works on your iPhone, Android and BlackBerry device.
The first step is to enter your name. To remain anonymous, never use your real name. I suggest using Fake Name Generator and selecting a country and gender that doesn’t represent you in anyway. Cryptocat also has translations for the following languages: French, Catalan, Basque, Italian, German, Portuguese, Russian and Swedish.
When you have entered your name and pressed enter, you will get the following prompt. For Chrome users, I suggest installing the recommended extension.
You will now be prompted to enter your nickname.
When you have entered your nickname, you will be required to type as randomly as possible in the box presented in order to create your keys.
Now, you will finally be in the chat room. But lets take a look around and see all the options first. First things first, there is a 256 character limit (which sucks), but it is better than nothing. You can add as many people as you want to the chat room using the link at the bottom of the chat room.
You can also click on any of the people who are in the chat room to view more details. For example, it will tell you how to send them a direct message that no one else in the chat room will see. In my case, it was @mrunknowns. You can also choose whether to accept or block messages from that person and you can verify their identity using the fingerprints.
Here is an example of a private message.
The circled button is how you widen the chat room (I took the shot with it widened) and the arrow points to the upload button which we will talk about more in the next image.
You can also send encrypted images to selected recipients. The maximum size as shown below is 512kb and documents aren’t allowed.
Lastly, you should always make sure your bar includes “HTTPS”.
Your computer, regardless of if you’re using it or not, is constantly communicating with the Internet. All of these conversations – held in the background – help keep your system and applications running at tip top shape. But some times there are some applications that just don’t need to communicate with the Internet, or even worse, some apps that send information about your computer and how you use the app without your permission or even knowledge. Little Snitch is an advance firewall application exclusively for OS X that allows you to control where an application can communicate to on the Internet. You can get Little Snitch from Objective Development for € 29.95.
A firewall is a virtual door controlled by an application on your computer that lies between your computer and the internet. Based on your rules, and its assumptions it will allow and deny connections through that door. This helps keep unwanted network connections from entering your computer, or in some cases, leaving it.
Testing for open ports in Terminal
However, there isn’t just one door for every single network connection to go through, there are hundreds! Each of these doors is called a port, and each port is used for different purposes. For example, normal web browsing is done through port 80, secure web browsing is done through port 443, and file transfer is done through 21.
Doesn’t OS X have a firewall?
While it is true that OS X has a built in firewall, it’s only half as good as Little Snitch. The default firewall only covers incoming connections, but allows all applications to make outgoing connections without restriction. This is where Little Snitch defines itself, by letting you control all connections, rather than half.
Setting up Little Snitch
It’s not hard to set up Little Snitch, just a simple download and install. However, you will need to restart your system after installing. This is because Little Snitch replaces a program called iptables, which is used for system networking. Don’t worry, Little Snitch doesn’t overwrite that program, it just replaces it.
The Configuration Window
When you load up Little Snitch for the first time, you will see that there are already a lot of rules created for you. Most of these rules have a lock on them, and are required for normal system operation. while you can disable them, you cannot (and should not) delete them. Selecting a locked rule will show a description of why it’s locked on the side.
The Rule list in Little Snitch
On the left hand side of the Configuration Window, you will see the rule filters. Check these every now and again for redundant or invalid rules.
By now, you’ve probably seen the Automatic Rule Creation dialog. This will come up every time a new application wants to make a connection, and there isn’t a rule regarding it. The new rule dialog will show you the application’s name, icon, and where it’s trying to connect to. You can allow or deny the connection:
Until you quit the application
Until you log out
Until you restart
For 15 Minutes
For 30 Minutes
For 1 Hour
For 2 Hours
You can go even further by controlling where the application can connect:
Only a specific port
Only a specific domain
Only a specific domain and port
With all of these controls, you can create a virtually unlimited number of rules for your apps.
Creating rules in Little Snitch
When creating filters, ask yourself “What does this application need to do?”. For example, a web browser like Google Chrome, Safari, or FireFox will need to connect to multiple domains and ports. Therefore, giving it a fully open rule would be the smart decision. From there, you can block specific domains if you need to. If you use any peer-to-peer applications like Transmission or uTorrent, you will need to allow it full network access for it to operate normally.
Manually Creating Rules
If you need a little more robust control when creating rules, or can’t launch the application until a rule has been made, you can create rules manually through the Little Snitch Configuration Window. To do this, open Little Snitch and select New Rule. The New Rule sheet will drop down.
At the very top, you can control if you want to block or allow incoming or outgoing connections. You can then choose the application, or set a global rule that applies to all processes. Below that is the fine tuning controls for how you want this rule to work. You will notice that there are a lot more controls than the automatic rule sheet, so go ahead and play around with them!
Manually creating rules in Little Snitch
So now that you got the basics down of Little Snitch, you’re all set to go out and take control of your privacy when using your Mac. There are plenty of programs out there that send tracking information without your consent. What are some applications that you discovered that are sending info back home?

When you hit the road, it’s easy to get paranoid—especially if you’re carrying thousands of dollars’ worth of technology with you. You can alleviate some of your worries by taking security measures to protect yourself against someone running off with your iPhone, iPad, or MacBook.
Use common sense
If you’re not used to toting a machine outside your usual rounds, don’t forget these precautions.
Don’t leave devices lying around: Don’t leave your laptop or other device on a table or counter at a coffee shop or other establishment and walk away or turn your back. Hardware is too easily snatched and too portable.
Don’t leave bags untended: Don’t walk away from a bag that holds your phone, tablet, or laptop. It’s simple for a thief to poke around without attracting notice, especially during the holidays when shops are busy.
Don’t use devices in unsafe locations: Don’t pull out that brand new iPhone or iPad device in an area where it can easily be snatched. This means both a dark, isolated street and densely-packed areas, like Times Square.
Don’t bother with laptop locks: At one point, we used to recommend using a locking cable with you laptop. But Apple has slimmed down the MacBook’s design and eliminated security slots.
Password protect your devices
What if a thief does get your device—is the trouble just beginning? It might be, if you haven’t bothered with basic methods for protecting your data.
Passcode lock your iPhone and iPad: Just because someone gets your phone or tablet, doesn’t necessarily mean he also gets unrestricted access to all your email messages, all your contacts, and—just for good measure—your Amazon.com account. Even if you don’t normally use a passcode or a screen or sleep lock, enable it before you travel. On iOS 4 and later, locking a phone or tablet prevents both access to the device and protects the data storage on it through encryption.
Password protect your MacBook: Do you really want to join the ranks of people who’ve compromised work data by leaving a laptop unattended and unprotected?
Launch the Keychain Access utility (in your /Applications/Utilities folder), and then select Keychain Access > Preferences. Select the Show keychain status in menu bar option. Now, whenever you step away from your computer, you can choose the lock icon in the menu bar and pickLock Screen. Make this process automatic by going to System Preferences and opening the Security & Privacy pane. Click the General tab and select the Require password option immediately after sleep or screen saver begins. You can adjust the time period using the drop-down menu here.
Encrypt for maximum protection
If you want to be sure that your computer’s data isn’t accessible to a more-than-casual snooper or to a thief who has all the time in the world, your best bet is full-disk encryption (FDE). FDE creates a strong encryption key, which it uses to encipher your entire hard drive. The key is held in memory while you’re in an active running session, and it is tossed whenever you shut down.
An FDE-protected system can only be backed up while it’s active. This prevents anyone (including governments and you) from recovering your data without a login account and password or an appropriate passcode.
Encrypt your drive with FileVault: Since Lion, Apple has provided built-in full-disk encryption through FileVault 2. You can’t recover a FileVault-protected disk’s data without an account and password. If you don’t like the configuration and options available from Apple, there’s also Sophos SafeGuard.
Encrypt key drives and files: You can also encrypt external drives, virtual drives (disk images), and individual files using Mac OS X’s built-in Disk Utility and other free and paid tools. Apple added external disk encryption in the Finder in Mountain Lion, too. See “Encrypt any disk in Mountain Lion.”
Rely on built-in iOS encryption: Nearly all iOS devices have hardware encryption built in. When the passcode is active, data is unrecoverable unless a device is jailbroken or otherwise compromised. This protection is automatic, and is only absent from the original iPhone, iPhone 3G, and first two iPod touch generations. Hardware encryption also allows a quick “remote wipe.”
Find a lost or stolen device
Even if your device is stolen or you simply mislay it in your travels, it’s possible to recover it if you’ve planned ahead. Theft-recovery software for mobile and desktop operating systems can track a device so long as it’s on a network. You might recall the recent story about ABC News purposely leaving an iPad at an airport security checkpoint, then using software to locate it at the house of a TSA employee? That’s not so unusual.
With a location in hand, police are often more willing to visit a home or business, as they frequently find where one device is located, other stolen gear is found. But many thieves are now too clever for such software, and prevent devices from joining a Wi-Fi network or even wrap hardware in aluminum foil to keep it off a cellular network.
Track it down with iCloud and Find My Mac: The built-in option for Mac OS X and iOS is Apple’s Find My Mac and Find My iPhone (which works for all iOS devices). This is activated in Lion and Mountain via the iCloud preference pane, and requires Wi-Fi to be enabled to provide tracking information. In iOS, theSettings > iCloud view has a Find My iPhone switch. You can find the current location of devices (Macs and iOS gear) associated with an Apple ID by logging in to iCloud.com with that ID or using the Find My iPhone app (which includes Macs in what it finds).
Find My iPhone/Mac can both lock a device remotely or wipe it clean. Apple goes so far as to allow a Good Samaritan to dial a number you’ve sent through Find My iPhone even when all other calls on the iPhone are disabled.
Use third-party software: Several third-party packages keep a constant low-level account of where a device is located. Others wait for a remote network trigger, checking in at regular intervals, that a device is stolen before they activate tracking. Some of them let you file a police report, see what a thief is typing, or even use your camera to snap a photo or video of the thief. Options include Gadget Track for Mac OS X ($20) and the iPad, iPhone, and iPod ($4); Absolute Software’s Lojack for Laptops ($40 for 1-year subscription);
In all cases, the software has to be installed before a device is stolen, and typically registered and activated. You also want to run a test to make sure it can be located while still in your clutches.
Always be prepared
It’s always hard to deal with the loss of an electronic device that contains personal and business data. By taking measures to secure your systems before you hit the road, you can defeat thieves before they get started, while helping Good Samaritans bring your precious hardware back to you.
