Hi, this is Gary With MacMost Now. On today's episode, let's learn about how to make your Mac book a little more secure browsing a public wifi network. Now if you have a Mac book or an IPad, you probably been in the situation when your browsing using a public wifi network. The problems with these networks is their not secure. Your information is sent in the clear in other words all the characters are just visible over the wireless signal. So people can use other computers and various pieces of software on the router and all points in between to see exactly what your transmitting, what your getting from the websites your visiting. So if your doing something, like say checking your email, or updating facebook that means they could see exactly what you are doing. Now its always best to avoid open public wifi networks for this reason. Maybe to use a network that has a password cause at least that means the data is encrypted that's being sent through the air. But a lot of websites also another solution. You can use https, the s stands for secure. You see this all the time when you say are going to pay for something at an E commerce website. It will change to https and you'll see a little lock symbol in Safari meaning that the data between your browser and the website are completely secure and encrypted. However, if your doing something such as checking your email, or updating Facebook, it may not be secure, but you can force it to be. So for instance, here I am inside of twitter and you notice that i am surfing twitter using http, so all this stuff is sent in the clear. Now i can add the s myself, manually. And you'll see the page just reloads and I am actually now securely surfing Twitter, you can even see the lock over there. so now all this data is being sent to and from the server encrypted and can't be read over a public wifi network. Now doing this manually isn't the best idea because your likely to forget and of course usually go to the website first and than you say Oh better add that s to it. And not all websites support it. But some of the major websites not only support it but have a setting that will force https if at all possible. So for instance if i go to my Twitter settings, I can look all the way at the bottom of the Twitter settings and i will see an https only setting. If I turn that on, than I don't have to worry about it again anytime I'm surfing twitter, it will be encrypted. Same thing is true in Facebook, if you go into your Facebook settings under my account than you look towards the bottom of the page, you can see an account security section, expand that and you've got the option to set it to browse Facebook on secure connection https whenever possible. Another site is Gmail, this also has under settings under general a setting right here for always use https. So there really is no reason why you shouldn't have all of those on if you use those websites. And also look at some of the other websites that you use all the time and see if they've got a setting to always force https. And some websites don't really need it, like for instance I noticed when surfing around on Amazon, since it's an E Commerce site I seem to just about always be in https and certainly whenever I was checking out or accessing account information. So there's just one way that you could be a little bit more safe when using a public wifi network. Til next time, this is Gary with MacMost Now.
