Is Encryption Sufficient?
Even if you have encryption related Internet security software, it might not be sufficient always. There are people out there who want to steal your data for their own benefits. They employ all possible tactics to get hold of your data so that they can use it for themselves or sell it off.
An encryption related security software encrypts only your data. There is much more to the data that travels on the Internet. This extra data, often found through headers, can reveal a lot about your browsing habits and may create particular interests in people who read it. These headers also reveal your Internet usage pattern to the hackers or anyone else interested in you.
The headers of each data packet reveal the source of data origin, the network it traveled through and the destination of data. If studied carefully by people with malicious intentions, this data can give out enough information that can be used to exploit you.
For example, if you are visiting an e-commerce website, the website may present you with increased rates for an item based on the country it intercepts by reading the data present in headers. Similarly, if you are accessing your company server from abroad, people can find out whom you work for and what servers you accessed - irrespective of whether the connection is encrypted.
After going through the above, you may have got an idea that using only an encryption software is not enough. You need anonymity too. Many people use proxy servers for anonymity. I suggest you use a pooled resource like "Tor" that makes it impossible for people to track you down.
