Why is Infrastructure Security Important?
Protecting infrastructure is crucial for keeping technology and data safe from harm, whether it’s from an attack or a natural disaster. It’s also important to minimize the damage if something does go wrong. The main goal of infrastructure security is to lower the overall risk for a business, which helps reduce the chances of big problems that could disrupt operations or hurt finances. This includes managing risks like cybersecurity threats, financial risks, and risks from third-party involvement.
Today’s businesses rely on complex IT systems, including both in-house and cloud-based systems, as well as a mix of devices like laptops, smartphones, and even IoT gadgets like cameras and sensors. But many of these devices weren’t built with security in mind, so it’s up to the organization to make sure they’re protected.
Infrastructure is like the backbone of a business’s tech setup, so securing it is key to keeping everything running smoothly. Think of infrastructure security as the main plan for keeping everything safe, guiding all the other security efforts a business puts in place. It’s the foundation for making sure all the pieces of the puzzle fit together securely, protecting what’s important to the business.
10 Best Practices for Securing Infrastructure
Here are some recommended best practices for securing infrastructure:
- Prioritize password security: Use strong, complex passwords for all logins, incorporating a mix of uppercase and lowercase letters, numbers, and symbols. Implement two-factor authentication whenever possible for added protection.
- Regularly audit user permissions: Review and update user permissions frequently to prevent unauthorized access. Remove access to services promptly when users no longer require them or upon their departure from the organization.
- Stay Up-to-Date with Patches: Install software patches promptly, especially those containing security fixes. Aim to apply patches on the day of their release to minimize vulnerabilities.
- Utilize Secure Protocols for Internet-Based Assets: Ensure that internet-facing assets utilize secure communication protocols like Secure Shell (SSH) and Secure Socket Layer (SSL) to establish secure channels, even across insecure networks.
- Remove Unused Services and Software: Eliminate unnecessary services and software to reduce potential security risks from idle but active systems. This practice, known as network hardening, enhances the overall security posture.
- Configure firewalls properly: Ensure that firewalls are configured correctly to effectively filter network traffic and prevent unauthorized access. Misconfigurations can render firewalls ineffective, leaving systems vulnerable to attacks.
- Follow Secure Development Practices: Incorporate secure coding practices into software development processes, emphasizing security throughout the development lifecycle. Approaches like Shift Left and DevSecOps promote a security-focused mindset within development teams.
- Implement encryption: Encrypt data wherever possible to protect it from unauthorized access. Encrypted files are considerably more difficult for attackers to exploit if they gain access to the system without the encryption keys.
- Regularly Backup Systems: Perform regular backups of all systems, storing copies offsite to safeguard against data loss from ransomware attacks or other incidents.
- Conduct regular stress testing: Regularly assess system security through comprehensive security scans and penetration tests to identify and address vulnerabilities proactively. This ongoing evaluation helps fortify infrastructure against potential threats.
Different Types of Tools to Safeguard Data
To safeguard your infrastructure and data, consider deploying these types of tools and security measures:
- Firewall: Install a firewall as your first line of defense against various threats, blocking malicious traffic from accessing your internal networks.
- Antivirus or Antimalware Systems: Deploy antivirus or antimalware systems to scan email messages, web traffic, and hardware devices, identifying and removing malware threats before they can infiltrate your systems.
- Penetration Testing and Vulnerability Analysis Tools: Utilize tools for regular or continuous scanning of your network, identifying potential security weaknesses and vulnerabilities that could be exploited by attackers.
- Intrusion Detection System (IDS): Implement an IDS to monitor your network in real-time, detect abnormal behavior or signs of a breach, and issue alerts to mitigate threats promptly.
- Authentication Software: Employ authentication software to monitor user activity on the network, utilizing AI to identify suspicious behavior indicative of compromised credentials.
- Password Auditing Tools: Regularly audit passwords to ensure users are not using weak or vulnerable login credentials, enhancing overall password security.
