How to set security group of amazon cloud to safely allow ports like FTP, MSDTC, MSMQ and filesharing etc.,
Posted on 2011-02-17
Currently launched few servers on Amazon cloud and I am looking for some security solution for cloud servers.
1. Looking for a tool where i can store all instances ip address with servername and use them to remote login when ever required instead of looking in to document everytime. If the tool has secured(encrypted login) login would be great.
2. Right now i have put rules in security group such a way that the RDP occurs only through corporate firewall by making entry as below.
Protocol from port to port source ip
RDP tcp 3389 3389 firewall ip/34
Similarly i want to secure other ports opened for sql, ftp and msmq etc.,
I cannot make same rule as ftp is used by clients.
other sql and msmq ports are opened as sql installed on different instances has to communicate. How do i make a rule that this communication should happen across onlu cloud infra?
rotocol from port to port source ip
- tcp 21 21 0.0.0.0/0
- tcp 1023 1024 0.0.0.0/0
- tcp 3372 3372 0.0.0.0/0
How do i make sure that allowing these ports are secure or safe. Is there a solution to make these ports open but from only cloud servers or from my office network?
Please help. thnx in advance.
