My company only allows few protocol outbound to internet like http and https. we are not currently allowing the FTP outbound. My question is that is the FTP protocol outbound access has some flaws or any security vulnerabilities inside it? Is there any reason, i should not allow FTP outbound for people in my company. Currently we are allowing only few FTP sites on firewall and blocking the rest.
This is only general oubound connections not inbound. My company staff members would like to have Full ftp access on port 21 outbound. is there any reason i should reject this request due to security vulnerability. I know the FTP is unsecure and passing the passwords clear text. Now a days you can use the http for the same aim as FTP like downloading and uploading files so blocking FTP seems not reasonable... what you think?
