I remember being very excited when I first started working from home. My home felt like an extension of my office, and I had almost unlimited access to corporate resources. I was thrilled about the freedom remote work offered me and my colleagues. However, I wondered if my network security was ready for this new working method. After all, remote work is the future—but are we prepared for it?
The distinction between work and home, or the conventional network perimeter, has vanished entirely due to the rapid expansion of remote work caused by the Covid-19 pandemic and the emergence of cloud computing. As a result, borderless networks have become more complex, and devices and applications are now commonly used. These factors make it challenging to manage security and identify vulnerabilities in the environment.
In addition, sophisticated threats such as advanced persistent threats are becoming more widespread. Even insiders can pose a significant security challenge by circumventing the perimeter with legitimate access.Over the years, many organizations have built their networks on outdated security systems and infrastructure not designed to secure a network with a vanishing perimeter.
Monitoring and analyzing network traffic across a WAN can be challenging, particularly when traffic is encrypted or passes through third-party networks. Limited visibility into network traffic makes it difficult to detect and respond to security incidents quickly.While modern network security can help overcome the challenges of vanishing network perimeters, transitioning to a future-ready network security strategy requires planning.
By integrating and coordinating these strategies, you can enhance your network security posture and mitigate the risks associated with the vanishing network perimeter.
