In today’s rapidly evolving digital landscape, cybersecurity is a paramount concern for businesses and organizations of all sizes. With threats constantly lurking, the need to strengthen security measures has never been more critical. While the focus often revolves around the latest devices and technologies, it’s equally important to consider the foundational aspects of cybersecurity, particularly the design of network infrastructure and secure communications.

Maximizing Cybersecurity Solutions: The Overlooked Key to Protection.

In this blog post, we’ll delve into the often-overlooked elements of infrastructure design that play a crucial role in fortifying an organization’s cybersecurity posture.

The Neglect of Infrastructure Design:

Far too often, businesses fall into the trap of prioritizing the acquisition of security devices while neglecting the proper design and implementation of their network infrastructure. The consequences of this oversight can be severe, and it’s essential to understand that effective cybersecurity should never be an afterthought.

  1. Network Segmentation:
    One fundamental but frequently overlooked aspect of infrastructure design is network segmentation. Network segmentation involves dividing a network into smaller, isolated segments to enhance security and overall traffic management. Without proper segmentation, an organization risks creating an environment where various departments can have unrestricted access to each other’s data or areas of the network. Network segmentation, when done well, can be used as the basis for further strengthening security posture by the implementation of additional security technologies, for example, firewalls, etc. The key takeaway here is that proper segmentation is used as a baseline for limiting/managing/restricting communications. Neglecting network segmentation can leave a network exposed both internally and externally and jeopardize the overall security posture.
  2. Zonal Strategies:
    In addition to segmentation, zonal strategies are vital for safeguarding an organization’s assets. Zones define logical areas within a network, and they play a critical role in enforcing security policies. For example, with zonal strategies in place, you can ensure that internal traffic adheres to specific policies and access control. Failing to implement these strategies means you may be deploying advanced security devices without optimizing their effectiveness. Zones can be deployed in conjunction with a proper network segmentation strategy.
  3. Embracing Zero Trust:
    The traditional approach of granting wide-ranging access upon logging into a corporate network is outdated and risky. Zero Trust and the principle of least privilege are emerging concepts that demand a fundamental shift in mindset. In a zero-trust environment, users are not automatically trusted, and they are only granted access to the resources they need. The emphasis here is to protect against internal threats, which are a significant concern in modern cybersecurity.
  4. Shifting From Traditional Perimeter Firewall Design:
    The traditional approach to securing a corporate network was the use of a Perimeter Firewall. This device was focused on protecting the organization against threats from outside-in. This approach did nothing to address the internal threats that are so rampant in organizations today. The world has evolved and fully appreciated the risks of internal threats and the recommendation is to combine the perimeter firewall approach with the installation of an internal firewall. This combination, along with supporting design approaches like Zero Trust will further strengthen the security posture of today’s organization.
  5. Patch Management:
    Many organizations invest heavily in security devices but overlook the importance of regular patch management. The capabilities of devices rely heavily on the software and firmware running on them. Manufacturers release patches and updates to address vulnerabilities and enhance performance. Failing to keep devices up to date by applying patches can severely compromise your security efforts.
  6. Best Practices in Design:
    Designing network infrastructure using industry best practices is often ignored in favor of quick device deployments. Proper device configuration and adherence to best practices are essential to ensure optimal security. Default configurations can expose vulnerabilities that attackers can exploit. A disciplined approach to following best practices from the ground up is crucial.
  7. Encrypted VPNs:
    With the rise of clear text transmission of data, even organizations with firewalls and multiple sites might be transmitting sensitive data without encryption. Implementing technologies like site-to-site encryption, even when the provider’s network is considered trusted, is a fundamental step in securing data in transit.

Infrastructure Design

Cybersecurity is not just about investing in the latest security devices; it’s about building a resilient security foundation. Infrastructure design plays a pivotal role in shaping an organization’s cybersecurity posture. To stay ahead in the ever-evolving cyber threat landscape, organizations need to prioritize network segmentation, zonal strategies, Zero Trust, internal firewalls, patch management, best practices, and encrypted communication. It’s time to shift our focus from mere device procurement to holistic security that encompasses infrastructure design, and in doing so, we can enhance our collective cybersecurity defenses.
