While running a local network security scan an administrator discovers communication between clients and one of the web servers is happening in cleartext. Company policy requires all communication lo be encrypted. Which of the following ports should be closed to stop the deartext communication?
正解：A
Port 21 is used for FTP (File Transfer Protocol), which is a protocol that transfers files between servers and clients in cleartext, meaning that anyone can intercept and read the data. To stop this communication, port 21 should be closed on the web server and replaced with a secure protocol, such as SFTP (Secure File Transfer Protocol) or FTPS (File Transfer Protocol Secure), which use encryption to protect the data. Verified References: [FTP vs SFTP vs FTPS]
