New Video from @collinsinfosec Explores Zero Trust Security Concept

In this video, CollinsInfosec explores the concept of "Zero Trust," a security approach that has gained popularity over the past decade. Contrary to popular belief, Zero Trust is not a single solution but rather a constantly evolving framework and strategy. The primary goal of this video is to demystify the myths surrounding Zero Trust and present its fundamental concepts. One of the main misconceptions about Zero Trust is that it is simply a new generation of marketing tools presented as "Zero Trust enabled." In reality, Zero Trust is a strategic framework that does not require replacing the entire network stack with Zero Trust-compatible platforms.

Instead, it involves enabling the use of applications while being aware of potential threats. This is where the concept of "allow listing" or "whitelisting" comes in, which involves creating a list of legitimate applications while blocking others. For example, if an application does not match the legitimate signature, it will not function, allowing for the filtering of malicious applications. Another crucial aspect of Zero Trust is the contextualization of application security. Even if a user's identity is compromised, it is important to monitor the applications being executed.

The concept of "ring fencing" introduced by Threat Locker allows for controlling interactions between applications. For example, if an application like PowerShell is "ring fenced," it can function as intended but cannot interact with other applications, thus limiting the risks of process injection or other attacks. The video also addresses the "never trust, always verify" model, which, although theoretically sound, can be difficult to implement on a large scale due to frictions between enablement and security.

Sometimes, it is necessary to give local administrative rights to users for specific tasks. This is where the concept of elevation control comes in, where administrative privileges can be granted in a limited and controlled manner. For example, a user can request access to a specific application for a limited period, allowing for controlled use of administrative privileges. Finally, the video emphasizes the importance of understanding potential threats beyond traditional perimeter defenses such as VPNs and firewalls.

Zero Trust is not just about the network but also about contextualizing identity, trusting devices, controlling applications, and elevating privileges. To understand threats, tools like malware analysis sandboxes can be used to analyze malicious applications in a test environment, enabling security analysts to better understand and respond to threats. In conclusion, Zero Trust is a holistic approach to security that goes beyond single solutions and marketing tools. It is a constantly evolving framework that enables legitimate users while restricting potential threats. This video provides an in-depth understanding of the fundamental concepts of Zero Trust and their application in real-world scenarios.
