Consult a great god, and of all stripes in the enterprise, how to protect the security of the development of the source code, we use the method is [a single shield the network environment, the virtual machine + SVN], developers can from another local area network (LAN) on the network to remote connection in development,

But now has a problem, that is, from the development environment must open a like 80 HTTP access port to the developer to debug with your mobile phone, as a result, the safety problems appear, thus source or other security data can easily be via HTTP download,

Excuse me each great god what method can be a safe method to eliminate the unsafe behavior, generally in large enterprises, and how do they do it can make the network mobile phones to access the development environment, and can protect the safety of the source code?
