Configuration drift occurs when network devices gradually deviate from their intended configurations due to unauthorized changes, misconfigurations, or system updates. This can severely impact network security, performance, and compliance. Left unchecked, it may lead to network instability, security vulnerabilities, and inefficiencies.
ManageEngine Network Configuration Manager offers an automated and reliable solution to identify and mitigate configuration drift. By providing centralized control over network configurations, Network Configuration Manager helps administrators maintain stability, enhance security, and ensure compliance across the entire infrastructure.
1. Automated configuration backups and restorations
One of the most significant challenges that network administrators face is ensuring consistent, up-to-date backups of network device configurations. If a device or system fails, administrators must rely on these backups for rapid restoration. Without frequent backups, network configurations are at risk of being lost, leading to extended downtime or recovery errors.
The Network Configuration Manager advantage:
-
Automated backup scheduling: Network Configuration Manager enables administrators to schedule automatic backups for all network devices, ensuring that configurations are consistently saved. This prevents human error and minimizes the chances of configuration drift from going unnoticed.
-
Instant rollback capabilities: In case of drift or errors, configurations can be restored with just a few clicks. The tool also tracks all backup versions, giving you the flexibility to revert to an earlier configuration with confidence.
2. Real-time configuration monitoring and drift detection
A key challenge in mitigating configuration drift is the lack of visibility into real-time configuration changes. Network devices might be modified either intentionally or inadvertently, but without automated tools in place, tracking these changes can be cumbersome.
The Network Configuration Manager advantage:
-
Real-time change monitoring: Network Configuration Manager provides a real-time monitoring system that automatically detects any changes to configurations across your network. Administrators receive instant alerts whenever a configuration change occurs, whether it’s a manual change or a system-driven update.
-
Audit trails and logs: The platform maintains detailed audit logs of every change, including the time, user, and type of modification. This log provides valuable insights for troubleshooting and ensuring that all changes are legitimate and within the defined policies.
3. Automated compliance and policy enforcement
As regulatory requirements become more stringent, organizations need to ensure that their network configurations meet compliance standards consistently. This is particularly challenging when there are multiple devices from different vendors across the network.
The Network Configuration Manager advantage:
-
Predefined compliance templates: Network Configuration Manager comes with a variety of predefined compliance templates for industry standards like the PCI DSS, HIPAA, SOX, and Cisco IOS. These templates enable organizations to easily enforce industry best practices and avoid configuration drift related to compliance violations.
-
Custom policy creation: For specific needs, administrators can create custom compliance policies tailored to their organization’s requirements. The tool will automatically validate and enforce these policies, ensuring that configurations are always compliant with the defined standards.
4. Automated configuration remediation with Configlets
When a deviation or configuration drift occurs, resolving it quickly is crucial. Manual remediation is often slow and error-prone, potentially extending the risk window and causing more issues.
The Network Configuration Manager advantage:
-
Configlets for automation: Network Configuration Manager offers Configlets, which are automation scripts used to configure devices, execute commands, and correct configuration issues. When configuration drift is detected, administrators can apply these pre-built Configlets to remediate the issues quickly and automatically.
-
Batch configuration updates: Admins can schedule bulk updates across multiple devices, ensuring that all configurations are compliant, reducing the chances of drift spreading across the network.
5. Integrated vulnerability management and patching
Configuration drift isn’t just about operational misconfigurations; it can also leave devices vulnerable to known security threats. As firmware vulnerabilities become public, keeping devices up to date and secure becomes paramount to maintaining network stability.
The Network Configuration Manager advantage:
-
Integrated vulnerability database: Network Configuration Manager integrates with databases like NIST’s National Vulnerability Database (NVD), identifying devices running outdated or vulnerable firmware.
-
Patch management and firmware updates: Once vulnerabilities are identified, Network Configuration Manager helps you apply firmware patches and updates automatically, ensuring that devices are always running the latest security fixes. This continuous patching cycle directly combats configuration drift, preventing network devices from being exposed to known threats.
6. Vendor-agnostic device support for consistent management
Many network management solutions are limited by vendor-specific configurations, leading to fragmented management and inconsistent configuration enforcement across a multi-vendor network.
The Network Configuration Manager advantage:
-
Vendor-agnostic support: Unlike many other tools, Network Configuration Manager supports devices from a wide array of vendors, including Cisco, Juniper, HP, Palo Alto, Fortinet, and more. This ensures consistent configuration management across the entire network, regardless of device origin.
-
Unified device management: Network Configuration Manager consolidates the management of all network devices under one roof, offering administrators a single platform for handling configurations, backups, compliance, and remediation across all devices.
