Help Network Configuration Manager Network Configuration Compliance

Network configuration compliance with our NCM tool

Our network configuration compliance feature, which is included in our network configuration management (NCM) tool, helps protect your networks from security threats that may arise from not adhering to industry standards and policies. It ensures that your network remains compliant with Cisco IOS, SOX, HIPAA, the PCI DSS, and any other customized policies.

What is network configuration compliance?

Network configuration compliance helps:

  • Implement rules and policies to defend your network from potential threats.
  • Ensure compliance with industry standards like Cisco IOS, SOX, HIPAA, the PCI DSS, or any other custom organizational policies.

Network administrators face a significant workload due to the increasing complexity of networks and the growing number of threats. Moreover, non-compliance with industry standards can lead to costly and risky consequences for organizations. Managing various network devices from different vendors is an overwhelming task; this is where our NCM tool helps.

The network configuration compliance feature in our NCM tool ensures network compliance by conducting compliance checks on backed-up device configurations. In the event of a rule or policy violation, network administrators are promptly alerted.

How it works

The NCM tool includes a set of rules, rule groups, and compliance policies that can be modified or added to by network administrators. These rules are essential for protecting the network. Rules are present in rule groups, and rule groups are present in compliance policies.

The NCM tool automatically backs up device configurations when a change is detected. To ensure compliance with network configurations, the NCM tool performs a compliance check and identifies non-compliance based on established policies that contain rule groups and rules. Accordingly, network administrators receive alerts based on their threshold settings.

Adding a compliance rule

  1. Navigate to Network > NCM > Compliance > Rules. You can view all the already available rules on the Compliance Rules page.
  2. Click the Add Rule button in the top-right section of the page.
  3. In the Add Compliance Rule pop-up, provide the following details:
    1. In the Display Name field, provide a name to identify the rule.
    2. Enter an appropriate Description.
    3. For Criteria, toggle to select between Simple, Advanced, and Custom as needed.
      1. Simple Criteria: Single pattern check allowed.
      2. Advanced Criteria: Multiple pattern checks allowed.
      3. Custom Criteria: Multiple pattern checks allowed within a single configuration block that start and end based on user-defined conditions.
    4. In the Configuration File field, select one of these options from the drop-down: should contain all lines, should not contain any line, should contain exact set, or should not contain exact set. Also select the number of time(s) the configuration file should be checked for a pattern that you will be entering in the next field.
    5. In the Pattern field, enter the value that should be checked.

      Figure 2. Adding a compliance rule with a Simple Criteria.
      In the example shown in Figure 2, the configuration file will be scanned for the pattern check. If it is present only once, then the rule is not violated. Otherwise, this rule is violated.
    6. If you select Advanced Criteria, provide the following details:
      1. In the Condition field, select one of these options from the drop-down: should contain or should not contain.
      2. For Pattern, provide the value that should be checked in the configuration file.
      3. Enter the number of times the pattern should be checked in the Time(s) field. 
      4. Click the plus + icon beside the Time(s) field to add more rows.

        Figure 3. Adding a compliance rule with an Advanced Criteria.
        In the example shown in Figure 3, the rule will be violated only if both conditions are not satisfied.
    7. If you select Custom Criteria, provide the following details:
      1. Provide a value in the Configuration Block Start and Configuration Block End fields to check for a value within a block in the configuration file.
      2. Provide additional criteria to be checked in the Configuration Block field. Select an option between should contain and should not contain in the drop-down. Then, provide the value that should be present within the block in the empty field beside the drop-down.
      3. Next, provide the pattern that must be checked within the block. This is similar to the steps provided in Advanced Criteria.

        Figure 4. Adding a compliance rule with a Custom Criteria.
        According to the given example in Figure 4, if a configuration file has a block that starts with check and ends with end, and includes the element date, it will be examined for the patterns utc (occurring any number of times) and GMT-4 (occurring once). If these conditions are present, a Critical alert will be produced for the rule.
    8. For Severity, toggle to select an option between Critical, Major, and Warning.
  4. Click Save.
