Using Conda behind firewall

 To use conda behind firewall, in Windows:

1) Edit the .condarc

channels:

- defaults

proxy_servers:

  http: <proxy_host>:8080

  https: <proxy_host>:8080

ssl_verify: False

NOTE: Beware doing something like this:

http: http://proxyhost:8080

https: http://proxyhost:8080

Don't add "http://" above, it's wrong!

2) Using pip (need to trust the hosts)

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org pandas

Some other better methods exist, the above is just one of the options that works.

Web Application Firewall (WAF)

By definition, WAF is going to filter out web request containing SQL injection, cross-site scripting, etc.
