System Hardening: Best Practices for Securing Servers and Workstations
Cybersecurity threats continue to grow, and protecting your server or workstation has never been more critical. In fact, the U.S. government allocated a staggering $18.78 billion for cybersecurity in 2021 alone. The reason for such a large investment is clear—cyberattacks are becoming more sophisticated, with adversaries increasingly targeting critical infrastructure.
The U.S. Department of Defense’s (DoD) Cyber Strategy Report highlights that cyberattacks, rather than traditional armed conflicts, are now a preferred method for adversaries to steal technology, disrupt governments, and compromise vital systems. In response to this escalating threat, many companies supplying servers and workstations to the DoD are turning to advanced system hardening strategies to meet security standards.
In this post, we’ll explore the concept of system hardening, its significance, the types involved, and why businesses must prioritize it.
What Is System Hardening?
System hardening is the process of securing a server or workstation by reducing its potential vulnerabilities. This involves minimizing the attack surface, or the points where cybercriminals can potentially breach a system. By closing off these entry points, the risk of a successful cyberattack is greatly diminished.
According to the National Institute of Standards and Technology (NIST), system hardening refers to a set of practices aimed at eliminating potential attack vectors. This includes patching vulnerabilities, disabling unnecessary services, and removing or disabling non-essential applications, ports, and user accounts.
At its core, system hardening is designed to safeguard a system from cyberattacks, with a focus on software security and reducing system flaws that hackers typically exploit.
Why Is System Hardening Important for Businesses?
The primary goal of system hardening is to minimize the number of potential entry points that an attacker could use to infiltrate a system. This aligns with the secure-by-design philosophy, ensuring that security is built into the system from the very beginning.
As businesses become increasingly dependent on technology, adopting system hardening practices is essential for safeguarding sensitive data, securing critical infrastructure, and meeting compliance standards. In industries such as finance, healthcare, and defense, where the stakes are particularly high, system hardening is not just a best practice—it’s a necessity.
Types of Hardening
System hardening encompasses a variety of techniques designed to secure different components of a computer system. These techniques are often tailored to the specific needs and configuration of the system in question. The five main types of system hardening include:
1. Server Hardening
Securing servers involves eliminating unnecessary services, ensuring up-to-date software patches, and strengthening access controls. This is a foundational practice for any organization relying on a server-based infrastructure.
2. Software Application Hardening
Hardening software applications focuses on securing the code, ensuring that applications are free of vulnerabilities that could be exploited by cybercriminals. This may involve regular software updates, secure coding practices, and minimizing the attack surface.
3. Operating System Hardening
Operating systems are a key target for cyberattacks. Hardening the operating system involves disabling non-essential features, applying security patches, and setting up proper security configurations to ensure that unauthorized users cannot gain access.
4. Database Hardening
Databases store critical business information, making them prime targets for attacks. Database hardening involves securing databases by applying access control, encryption, and regular updates to ensure they remain protected from potential breaches.
5. Network Hardening
Network hardening involves securing the communication channels that link various systems. This includes configuring firewalls, securing wireless networks, and using encryption protocols to prevent unauthorized access and mitigate the risks of data interception.
