Agentless configuration drift detection and remediation
Over time, application owners find themselves compelled to continuously refine their applications and the underlying infrastructure to enhance the products they deliver, whether to internal or external customers. These modifications inevitably lead to changes in the configuration of both applications and infrastructure. While some of these changes may be benign, others can unintentionally steer the systems away from their securely configured state, a phenomenon commonly referred to as "configuration drift." Left unaddressed, the extent of this drift can introduce substantial risks to the organization.
Traditionally, agent-based automation configuration management tools have been favored as the primary solution for tackling configuration drift.
However, is this approach genuinely the most effective strategy?
According to AWS's well-architected framework, the concept of a Fault Isolation Zone (FIZ) is crucial, characterized by isolation boundaries like Availability Zones (AZ), Regions, control planes, and data planes. While this concept is centered in a cloud context, the principles behind FIZ remain relevant in traditional data centers and at the network edge. The core idea is to minimize the impact of errors, particularly human misconfigurations, that can propagate beyond a defined Fault Isolation Zone.
Are misconfigurations resulting from human error still a matter of concern?
