Rack911: Complex Infrastructure Solutions

Linux Server Hardening

Because nobody wants a soft server.

It’s rough out there for a server. With the constant threat of cyberattacks looming on the horizon, organizations around the world are spending billions to beef up their cybersecurity and protect sensitive data from prying eyes.

Rack911 works with customers to enhance server security using a wide range of methods in a process known as Server Hardening. Following a server security audit,  our experts will identify various ways to enhance cybersecurity across the network, hardening the server to protect it from both external and internal threats.

Some methods employed by our experts include, but are not limited to:

  • Firewall installation/configuration: A common security system that monitors and controls incoming and outgoing network traffic.
  • Encryption for data in transit and at rest: By automatically encoding messages and information, this process ensures that data can only be read by the intended recipient.
  • Disabling unnecessary software: Various software included in default OS configurations can provide hackers with additional entry points to the network. Identifying and removing these unnecessary programs is a fast and easy way to enhance overall server security.
  • Multi-Factor Authentication (MFA): Single passwords are often not enough to protect your most sensitive information. Multi-factor authentication requires the use of multiple authentication factors—such as passwords, tokens, or biometrics—to better protect user credentials and resources.
  • Automatic server logs: Maintenance of a comprehensive history of server activity makes it easier to identify and mitigate potentially harmful activity.
  • Login failure daemon: Blocks brute force hacking and system intrusion attempts.
