Enhancing Server Security to avoid Hacking Attacks

Password Security — A Good way to prevent unauthorized access

  • Use strong passwords with a minimum length of 8 characters because stealing or guessing a password with long length is difficult.
  • Try to enhance the complexity of your password by using mixed characters e.g. include numbers, alphabets, special characters.
  • Avoid using keywords in your password because these are known in dictionaries.
  • Use different passwords for different modules on your server.
  • Avoid using personal information as a password because social engineering can easily help to gain access to your server.
  • Avoid repetition of sequences in your password.
  • Keep updating your password with time.
  • Don’t store passwords on your phones, tablets, computers or anywhere, keep them in mind. Extracting saved passwords from any device is not a tough job.
  • You can use a password generator to generate a strong password.

Secure Communication — Server communication must be secured

  • Use secured FTP ( SFTP ) (port 22) instead of using simply FTP for communicating with servers via FTP clients like FileZilla.
  • Use SSH because it is a cryptographic network protocol and can operate networking services securely over an unsecured network.
  • Use POP3S/SMTPS/IMAPS for email connections.
  • If you can, you must use VPN.
  • Setup firewall to monitor and control incoming and outgoing connections.
  • Use encryption if possible.
  • Avoid using public internet or public computers to access your servers
  • Install SSL ( Secure Sockets Layer ) for all the administration areas and hosted domains on your server.
  • You can try Let’s Encrypt for installation of SSL certificates. Let’s Encrypt provides free SSL certificates to everyone to provide the secured environment.
