Guide to Industry-Accepted Hardening Standards

The goal of systems hardening is to further protect your organization by reducing vulnerabilities in your applications, systems, and information technology infrastructure. By doing so, you’re creating less opportunity for malicious attacks and operational malfunctions because you are removing unnecessary programs, applications, and access points that increase the security of your system. Just as removing unnecessary hazards on a busy interstate increases traffic flow and reduces risk of accidents, removing unnecessary technology in your system decreases the risk of malicious activity and can increase overall operational productivity.

System Hardening Standards

For all the parts of your ever-changing systems, you want to prevent attacks and vulnerabilities as best you can. Hardening your network, servers, applications, database, and operating systems is a great start to meeting industry-accepted configuration standards. Your hardening standards will vary as your systems and technology will differ, but you can focus on developing standards to implement these five areas of system hardening:

Network Hardening

  • Firewall configuration
  • Regular network auditing
  • Limit users and secure access points
  • Block unnecessary network ports
  • Disallow anonymous access

Server Hardening

  • Administrative access and rights are allocated properly
  • Secure your data center where servers are located
  • Disallow shut down initiation without log in

Application Hardening

  • Application access control
  • Remove default passwords
  • Implement password best practices
  • Configure account lockout policy

Database Hardening

  • Implement admin restrictions on access
  • Encrypt data entering and leaving the database
  • Remove unused accounts

Operating System Hardening

  • Apply necessary updates and patches automatically
  • Remove unnecessary files, libraries, drivers, and functionality
  • Log all activity, errors, and warnings
  • Limit sharing and system permissions
  • Configure file system and registry permissions

The implementation of these hardening techniques is by no means a comprehensive approach to security, but it’s a great start to ensure your organization is headed in the right direction for a more secure information security program. By gathering the right tools and techniques, you can set yourself up for security success.
