8 Best Practices for Securing Your Infrastructure Solutions

The worst nightmare for any business is discovering its entire infrastructure compromised—data stolen, systems offline, and reputation damaged.

A Verizon 2020 Data Breach Investigations Report  says that

67% of data breaches involve stolen credentials

But here’s the good news: you can avoid this scenario with the right security practices. 

Protecting your infrastructure solutions is easier than it sounds, and the steps you take today can save you from devastating losses tomorrow.

So, what are the best ways to secure your systems? 

Let’s explore eight essential strategies that will keep your infrastructure safe and sound, ensuring peace of mind for you and your business.

1. Strengthen Authentication Methods

The first step in securing your infrastructure solutions is to have strong authentication methods. This means ensuring that only the right people can access your systems. A great way to do this is by using multi-factor authentication (MFA).

MFA requires users to provide two or more pieces of information—such as a password and a fingerprint or a code sent to their phone. This adds a strong layer of protection and makes it much harder for hackers to get in.

Why Strong Authentication Matters

• Weak passwords are an easy target for hackers, especially in a remote work environment.

• Multi-factor authentication (MFA) adds an extra layer of security, reducing the risk of unauthorized access.

• With MFA, even if passwords are compromised, hackers still need additional information to break in.

2. Keep Your Systems Up to Date

Regularly updating your systems is one of the easiest ways to protect your infrastructure solutions. Cyber attackers often exploit known software vulnerabilities, so keeping everything updated helps close those security gaps.

Make sure to regularly update your operating systems, software, and security tools to keep them secure. This helps prevent attacks from taking advantage of outdated systems.

Automating Updates

Manual updates can be forgotten or delayed, which leaves your systems exposed. Automating updates ensures your infrastructure always stays up to date with the latest security patches, minimizing the chance of an attack.

3. Encrypt Your Data

Data encryption is a smart way to protect your information. When you encrypt your data, it turns into unreadable code that only authorized people can decrypt. This makes it nearly impossible for cybercriminals to steal or access your valuable data.

Whether it’s data stored on your servers or information being transferred over the internet, encryption ensures that your data stays safe, even if it falls into the wrong hands.

How to Encrypt Your Data

• Use strong encryption algorithms like AES-256 to secure sensitive data.

• Always keep your encryption keys in a secure location and rotate them regularly to maintain data safety.

• Encrypt both data at rest (stored data) and data in transit (data being transferred) to safeguard all information.

By taking care of these details, you ensure that your data remains protected from any prying eyes.

4. Use Firewalls and Intrusion Detection Systems

Firewalls and Intrusion Detection Systems (IDS) are essential for protecting your infrastructure. Firewalls act as barriers between your internal systems and external threats. IDS helps you monitor network traffic for any suspicious activity.

Together, these tools act as your first line of defense against attacks, blocking harmful traffic before it can do any damage.

How Firewalls and IDS Work Together

When paired together, firewalls and IDS provide a strong defense system. Firewalls block unauthorized traffic, while IDS alerts you to any unusual activity. This combination keeps your network safe and gives you the power to respond to threats quickly.

A quote from Gartner states that

Information security systems such as hardware, software, and network that exchange and store information involves solutions such as firewalls, encryption, and intrusion detection system.

5. Regularly Conduct Security Audits

Security audits are an excellent way to stay on top of potential risks. During an audit, experts check your systems, applications, and network for weaknesses that hackers could exploit. This helps you find vulnerabilities before they turn into serious problems.

Security audits also ensure that your infrastructure meets industry standards and compliance requirements, such as GDPR or HIPAA.

Don’t wait for an issue to arise. 

Regular audits help you stay ahead of any vulnerabilities that could develop. With ongoing audits, you can be sure your systems are always secure.

6. Segment Your Network

Network segmentation is another great way to secure your infrastructure solutions. By dividing your network into smaller sections, you limit the spread of attacks. If one part of your network is compromised, it’s harder for the breach to affect the entire system.

This also makes it easier to control access to sensitive areas. Only those who need access to certain data or systems will have it.

How to Segment Your Network

Start by identifying which assets are most important to your business. Then, divide your network into separate zones, such as public, private, and restricted areas. Use tools like firewalls and VLANs to control who can access each zone.

7. Train Your Team on Security

Your employees play a crucial role in securing your infrastructure. Human error is often the cause of security breaches, so it’s important to train your team on best practices.

Provide regular training on recognizing phishing emails, creating strong passwords, and understanding the importance of data protection. A well-informed team can help prevent cyber attacks from happening in the first place.

Building a Security-Aware Culture

Security training isn’t just for IT staff. Everyone in the organization should be trained on how to protect company data. By making security a priority for all employees, you build a culture of safety and vigilance that will help keep your infrastructure secure.

8. Backup Your Data Regularly

Data loss can happen for many reasons—system crashes, cyber attacks, or even natural disasters. To ensure that your business can keep running in case of a data loss event, regularly back up your data.

By backing up your data, you ensure that you can quickly restore it if needed. Having a solid backup plan reduces downtime and keeps your operations running smoothly.

Best Practices for Data Backup

• Set up automated backups to ensure consistency. 

• Test your backups regularly to make sure they’re working and that you can restore your data when needed. 

• By having a strong backup system, you can protect your business from unforeseen disasters.

Conclusion

Securing your infrastructure solutions is not a one-time task. It requires ongoing effort, attention, and a proactive approach. By following these eight best practices—strengthening authentication, keeping systems updated, encrypting data, using firewalls and IDS, conducting regular audits, segmenting your network, training your team, and backing up your data—you can create a solid foundation of security for your infrastructure.

Taking these steps will not only protect your systems and data but also help you build a more resilient business. Implement these strategies today and start securing your infrastructure for a safer tomorrow.
