Such a disciplined approach fosters predictability within the IT sphere, curtailing unexpected behavior and bolstering operational dependability.
Maintaining an up-to-date Configuration Management Database (CMDB) is key. It provides a consolidated perspective on the organization’s hardware and software deployments. This visibility is essential for promoting transparency and facilitating better informed decision-making in the workplace.
In essence, diligent configuration management is indispensable for a predictable and secure IT environment, and it embodies the proactive steps necessary for achieving optimized and reliable operations.
Causes of Configuration Drift
Configuration drift is a common challenge that plagues many IT environments, gradually leading systems away from their original, secure configurations. It can manifest in various ways but typically results from inadequate change management and oversight.
Let’s delve into the root causes that contribute to the phenomenon of configuration drift.
Human errors
At the forefront of configuration drift causes is human error, accounting for a significant percentage of configuration inconsistencies.
These errors can arise from a number of situations such as failure to follow established procedural guidelines during changes, lack of proper understanding, or simple mistakes that accumulate over time, slowly steering the system away from its intended baseline configuration.
CrowdStrike’s report indicates an alarming 95% increase in cloud exploitation incidents year-over-year in 2022, many of which were attributed to human errors. Operations teams attempting to manually track and rectify misconfigurations can lead to an inefficient use of time, further compounding the likelihood of additional errors. Operational human errors persist as a notable threat, even with the adoption of containers and immutable VMs in cloud environments. This underscores the continual need for practices aimed at reducing these errors to combat configuration drift.
Software updates
While undeniably critical for ensuring a system’s security and functionality, software updates themselves can inadvertently introduce configuration drift.
New network services or altered settings post-patch can result in an environment that deviates from the documented configuration standards, leading to inconsistencies. These updates are indispensable for mitigating security vulnerabilities, yet they require meticulous oversight to ensure that after their application, systems remain stable, secure, and in compliance.
The act of documenting changes during software update processes is paramount; failure to do so may lead to unrecognized configuration drift, undermining both the system’s integrity and the configuration management efforts.
Environmental changes
Environmental changes encompass a broad scope of actions, including manual interventions and ad hoc fixes, particularly in production environments where quick resolutions to outages are imperative.
However, these expedient solutions often bypass the necessary step of reflecting changes in the configuration’s documentation, resulting in drift from the baseline.
Ongoing software updates, while essential, can also contribute to configuration drift. Without careful analysis and subsequent updates to the baseline configuration, these software-induced changes can cause significant misalignment over time. Ensuring these alterations are properly assessed, recorded, and integrated into the standard configuration is critical for maintaining the integrity and reliability of IT systems.
In summary, managing configuration drift necessitates a vigilant and disciplined approach encompassing rigorous documentation, adherence to established procedures, and vigilant monitoring of changes, whether induced by human interaction or software updates.
