Perimeter security refers to natural barriers or built fortifications to either keep intruders out or to keep captives contained within the area the boundary surrounds.[1]

Perimeter security starts with secure network design; using firewalls at external connectivity points, applying and maintaining stringent firewall settings, enforcing VPN for remote access, encryption-in-transit and for data-at-rest, and authenticating all users access. [2]

Securing The Perimeter is shown in figure 1. Securing the perimeter in the cloud is a crucial aspect of ensuring the security of your organization's digital assets. When you move your data and applications to the cloud, you need to be aware that the traditional perimeter-based security model may not be as effective as it once was.

Here are some steps you can take to secure the perimeter in the cloud:

• Use multi-factor authentication
• Implement network segmentation
• Use encryption
• Regularly update and patch your systems
• Monitor and audit your systems

Cloud Perimeter Security Needs The Right Maintenance

Like all things in cybersecurity, cloud perimeter security requires continual vigilance and proper maintenance. No system, especially not in the era of cloud migration, is set-it-and-forget-it. You need to invest time, resources, and expertise in making sure it is as strong as possible. Only then can your enterprise truly transform into a leader in the digital marketplace!

securing the perimeter in the cloud requires a different approach than traditional on-premises security models. It's important to implement a range of security measures, including multi-factor authentication, network segmentation, encryption, regular updates and patching, and monitoring and auditing of systems. However, it's also essential to understand that security is an ongoing process, and organizations need to remain vigilant and proactive to protect their digital assets. With the right approach and tools, it's possible to secure the perimeter in the cloud and minimize the risk of security breaches.
