Security of Your FTP Servers

Numerous firms are facing risks related to breach of data or a sizeable non-compliance punishment due to the widespread use of poor FTP deployment procedures. A file transfer protocol (FTP) server is a way to centralize, simplify, and automate your data movements. You should ensure the compliance and security of your servers through the tips provided in this article. 

Use Strong Passwords

You should use passwords having certain characteristics. They should at least have seven characters. A strong password combines alphabet, numbers, and alphanumeric characters. The passwords should be changed every three months. The passwords should not be reused and they should be stored using string algorithms.

Utilize Hashing and Strong Encryption

The FTP protocol employs encryption ciphers to safeguard data while it is being transmitted. The cipher, a sophisticated algorithm, transforms the information into encrypted data for transmission using a unique password. Disable any antiquated, dated ciphers and simply use better ciphers, such as AES, as soon as possible. MAC algorithms help in verifying the integrity of the data being transmitted. You should disable the antiquated MAC algorithms and use stronger ones instead.  

Back Off a Gateway

The DMZ is a typical network area where businesses keep their FTP servers. Data files and user passwords of communicating partnersare typically kept on an FTP server in the DMZ, which poses a significant security concern even if the files have encryption. Moving user credentials and files into the safe, private network is a step other organizationsare taking. The issue with this approach is that it opens a door for an attack and might not adhere to compliance standards. A strategy that is gaining ground is the usage of an improved reverse proxy or a DMZ Secure Gateway. 

IP Blacklist and Whitelist

A list of IP addresses can be blocked from permanently or temporarily accessing the system using an IP blacklist. You might, for instance, want to restrict access to particular employees or departments within your organization. Additionally, you can instruct the FTP server to automatically prohibit certain attacks, such as DoS attempts.Another strategy is to restrict system access to only those IP addresses that are whitelisted. 

Make Your FTP Server Stronger

You must take some precautions you’re utilizing an FTP server.To keep it safe, useExplicit FTP only if the data channels are forced to be encrypted. Avoidutilizing any SSL versions or employing algorithms with elliptic curves.

Good Account Management 

Making OS-level user accounts for business partners is dangerous since it opens the door to accessing additional server resources. Additionally, user credentials must be maintained apart from the FTP program. Do not permit shared accounts or anonymous users. Establish some guidelines, such as requiring account user names to contain at least seven characters and automatically deactivating accounts following six failed login attempts or ninety days of inactivity.

Like everything that utilizes the Internet, FTP servers are also vulnerable to cyberattacks and malicious hacks. However, they are preventable in most cases if an organization follows and employs the above tips.
