#Secure ftp server software
Your best defense is to implement software that will recognize these attacks and automatically block the source IP of the attack from further connections. Not only do these attacks risk unauthorized access to your system but they also can put a heavy load on your system that will affect other users. If you take a close look at your FTP server logs you will likely see clues of these attacks being launched against your system.
#Secure ftp server password
Detect and respond to password attacksĪs described above, brute force password attacks are very common. It is also recommended to implement some sort of password aging mechanism so users are required to change their passwords on a regular basis. Enforcing strong passwords with a minimum of 8 characters including alpha-numeric, uppercase and lowercase characters is highly recommended. Brute force password attacks against FTP servers are common and with enough time can grant unauthorized users access to your FTP server. Users often choose weak passwords that are easy to remember and are typically based on dictionary words. One of the biggest holes in FTP servers are weak passwords. For example, if a user only needs to upload files then other permissions like downloading files and deleting files should be disabled. Additionally, each user should have their own set of permissions which limits their functionality to only what they should be doing. This does not mean that you cannot have one or more directories that are shared by multiple users in your system, but providing access to these directories should be done explicitly rather than allowing all users to have access to all directories by default. This ensures that users cannot access the files of other users. Define user accounts and permissionsĮach user should have their own user account and unique login directory. If you decide to use explicit FTPS then it is recommended that you configure the server to force users to switch to a secure connection, otherwise your users may connect insecurely. The difference between these is that in implicit FTPS the connection is always secure, whereas in explicit FTPS the client must explicitly tell the server to switch to a secure connection. Both of these protocols use SSL/TLS to secure both the command and data channels protecting both the commands and data exchanged between the client and server. When using the FTP protocol this can be done using implicit FTPS running on port 990 or by using explicit FTPS running on port 21. The first step towards a secure FTP server is to encrypt the connection since an unencrypted connection means your data and user credentials are sent over the Internet without any protection. One of the other advantages of secure FTP server is its capability to automatically detect sensitive data like cardholder data and ePHI, and its ability to help in password management.Do you need to secure your FTP server? Here are 5 steps that you can take towards a secure FTP server and ensuring your data and users are protected. A secure FTP server is also capable of recording file transfer events this helps in audits/compliance or to support troubleshooting. It provides a data-at-rest encryption feature which helps to keep the file contents secure during storage. It maintains high access control, meaning only authorized users can access the files.
A secure FTP server helps to keep the file contents secure during transmission.
It also capable of preventing malicious users from impersonating legitimate uses to gain access to files. It can detect files which are subjected to unauthorized changes, and as such provides greater data integrity. There are benefits associated with a secure FTP server.
Certain advanced secure FTP servers such as JSCAPE MFT server often provides both SFTP and FTPS protocols along with other file transfer protocols. A secure FTP server also makes use of protocols to provide security features such as authentication, encryption or data integrity, password management and access control mechanisms. A secure FTP server supports many actions on files such as file transfers comprised of multiple files, remote file management activities, creations of directories and deletions related to directories and directory listings.
