We are in the process of making our site PCI compliant. One of the vulnerabilities we are facing is as below.
Description: SSL Version 2 (v2) Protocol Detection (for ftp) Synopsis: The remote service encrypts traffic using a protocol with known weaknesses. Resolution: Purchase or generate a proper certificate for this service.
Another one is as below (the program is again FTP)
Description: SSL Certificate Cannot Be Trusted Synopsis: The SSL certificate for this service cannot be trusted. Resolution: Purchase or generate a proper certificate for this service.
After studying things I think we need to purchase a SSL certificate for FTP. Now I have some questions
1) When I try to purchase an SSL certificate for FTP there is no option for SSL certificate specific for FTP. So which should we buy? I know this might depend on my security company (like Thwate, Verisign etc..) but if possible then can someone give an example? 2) Our site does have HTTP SSL and it is installed perfectly and working perfectly so will the same certificate (HTTP SSL Certificate) work for FTP too?? 3) Which should we configure here, FTPS or SFTP?
