I have just decided to get a smartphone and now have a Galaxy S3 through Verizon. It has Jelley Bean...Android version 4.1.1

I have a 2 gig data plan that is shared with my wife's identical phone.

Because of the data limit, I am wanting to use a WIFI connection when available but am concerned about security. I have installed Avast Mobile Security on our phones.

I have been trying to find information on using public WIFI on my Android Phone and how best to keep my phone secure.

Any help would be appreciated.

There are a few WIFI security protocol standards. The 1st and probably the worst is WEP (Wired Equivalent Privacy), it has the weakest security features and difficult to setup properly. Therefore it is the easiest to hack. If your own network is setup with WEP, then I recommend you use a different protocol. I think it is fine if you are simply browsing for a short period of time. But I would avoid using any WIFI network using WEP for a prolonged period of time (15 - 30 minutes). Never ever transmit confidential information over a WIFI network using WEP. Don't buy anything, don't log into your bank account... nothing.

WPA and WPA2 stands for WIFI Protected Access (version 1 and 2). These are the most secure protocols, WPA2 is more secure. You should setup your own WIFI network using these protocols (WPA2 is preferred). A bit technical, but the main difference between the two is the Advanced Encryption Standard (AES) in WPA2. Security using AES encryption is the official standard used by the US government to encrypt top secret information.

WPS (Wi-Fi Protected Setup) is a more recent security protocol which I just became aware of this week. It is designed to make setting up a secured WIFI network easier. But it turns out that making while making a WIFI network easier to setup, it also makes it less secure. How much less is unknown to me. Is it at least better than WEP? I don't know.

In short, WPA and WPA2 are the way to go. If the WIFI hotspot you are in uses those protocols (especially WPA2), then you should be fine. Can you still get hacked? Yes, theoretically you still can. For the best security you want a direct wired internet connection. It is the absolute most secure way to connect to the internet... but it is still possible to get hacked.

Hotspots using WEP or WPS should be okay for simple browsing. But if you are the overly cautious type, then you will want to simply avoid using any WIFI hotspot that uses those security (or lack thereof) protocols.

Thanks for taking the time to respond. I really don't understand most of what you said, but guess you do. I was looking for simple steps I can take to be safe using WIFI Hotspots. I guess what I'd take from your post and thinking about it is not to use a WiFI Hotspot expecially if I'm wanting to do something that would open me up to credit theft or bank theft. Since the amount of data used for occassionally doing things like simple email and web browsing, and my banking or purchasing is minimal, I think what I've decided is to not use hotspots...use my Verizon 4G LTE Data Plan.
