CiscoWorks Network Compliance Manager (NCM) tracks and regulates configuration and software changes throughout a multivendor network infrastructure. It provides superior visibility into network changes and can track compliance with a broad variety of regulatory, IT, corporate governance, and technology requirements. NCM helps IT staff identify and correct trends that could lead to problems such as network instability and service interruption.
Enterprises seeking to facilitate high performance business applications increasingly rely on sophisticated networking infrastructure and the power of new technologies. Network operations and security managers rely on systems that can automate network deployments, handle large and complex topologies, and track and audit how actual network deployments comply with design requirements and best practices. Enterprise networks must comply with regulatory policies, corporate IT methodologies, and technology best practices - independently of scale, networking technologies deployed, and the combination of vendors providing networking equipment. NCM helps users meet regulatory compliance goals and enforce internal IT best practices.
Network Lifecycle Automation
NCM automates the complete operational lifecycle of network devices, which includes:
• Discover and track: Includes discovering and cataloging the network, visualizing the Layer 2 and Layer 3 network topology, initial device turn-up, and creating initial snapshots of device configurations
• Change and configure: Includes creating and deploying configuration changes in a structured manner, such as using configuration templates or scripts, peer reviewing and approving proposed changes, and maintaining an archive of previous configurations
• Audit and enforce: Includes defining compliance policies for your network devices, detecting violations in real time, and autoremediating problems
• Maintain and support: Includes providing reports on device inventory, change activity, and compliance
Enforce Policies, Standardize Operations, and Meet Compliance
Bringing networks into compliance with corporate or regulatory standards is a nontrivial, labor-intensive,
error-prone, and difficult task. NCM helps you meet compliance standards through a network compliance model that maps device information, including configurations and run-time diagnostics, as well as policies and user roles, into a normalized structure to prevent compliance violations before they occur.
Built-in best practices immediately measure network compliance against industry-accepted best practices. NCM incorporates policies such as the National Security Agency (NSA) router configuration guidelines.
Predefined reports for Information Technology Infrastructure Library (ITIL), the Sarbanes-Oxley Act (SOX), the Health Insurance Portability and Accountability Act (HIPAA), the Payment Card Industry (PCI) standard, and other regulations offer immediate insight into network compliance. These reports provide the metrics that each of these regulations or processes requires, increasing visibility and saving auditors and network engineers time.
Prevent Network Downtime and Increase Stability
Peer reviews can reduce the number of configuration defects in a network. NCM automates peer reviews, ticketing, and approval processes to reduce the time between approving a configuration change and implementing it on your network.
New Features in NCM 1.7
NCM 1.7 includes the following new features:
• Allow full policy management from the API: A rich set of new API commands is now available to define, provision, edit, and list NCM policies. These new APIs can be issued in various combinations to externally create and edit policies for use to help ensure network device compliance.
• Network device detection using Simple Network Management Protocol Version 3 (SNMPv3) configuration: Network devices using SNMPv3 for device discovery are now detectable using NCM. Using less secure network device detection methods is avoided when SNMPv3 is used with NCM 1.7, facilitating the use of the most up-to-date SNMP security mechanisms.
• Device group user interface display enhancements: The display of device groups has been enhanced to facilitate hierarchical structure viewing of device groups. High performance rendering of user-selected device groups while preserving the "parent - child" relationship of groups and subgroups is reintroduced in NCM 1.7.
• Custom notifications to logged-on users: Administrators of the NCM solution can create customized messages that can serve as notification messages to all logged-in users. Administrators of the NCM solution can now see the email address of all logged in user IDs and send emails to selected users. This helps administrators better manage users accessing the NCM application.
• HP Network Node Manager (NNMi) integration enhancements: Single sign-on between NCM and NNMi, embedded interfacing between NCM and NNMi, and SNMP community string forwarding between NCM and NNMi.

Network lifecycle management
NCM delivers a complete management and automation solution to support the full lifecycle of your network.
Using integrated, single-source software, automate IT workflows for otherwise manual processes, accomplished primarily through complex scripting.
Real-time configuration and asset tracking
In real time, detect configuration and asset information changes made across a multivendor device network, regardless of how each change is made.
Perform rapid troubleshooting and manage network compliance by comparing devices to well-defined, best-practice standards. Control noncompliance with automatic remediation of devices that violate standards. Speed internal and external audit processes with predefined network compliance reports for ITIL, SOX, HIPAA, PCI Data Security Standard (DSS), and more. Validate device operating states in real time to stay in compliance.
Diagramming and visualization, including Layer 2 and Layer 3 modeling
Generate a graphical representation of your network. Identify which devices are inactive or out of compliance. Use filters to immediately view isolated specific network segments. Capture a snapshot of the current state of the network, including topology and virtual LAN (VLAN) information. Identify the hosts connected to specific switches or interfaces by MAC address.
Automated software image management
Update device images and feature sets quickly, reliably, and easily.
Real-time audit trail
In real time, store a complete audit trail of configuration changes (hardware and software) made to network devices, including critical change information.
Role-based access control
Configure granular, customizable user roles to control permissions on device views, device actions, and system actions. Support common authentication systems, such as TACACS+, RADIUS, SecurID, Active Directory, and Lightweight Directory Access Protocol (LDAP).
Template-based device provisioning
Automate routine configuration tasks for updates, such as password or community string changes. Reduce the time needed to build automation scripts and increase accuracy with autogenerated scripts derived from device sessions.
Automated software synchronization and image management
Create a repository, and synchronize all device software images across your enterprise network. Use image management to automatically identify, download, and install the recommended software image for your network devices.
Create complex automation flows, integrating internal and third-party systems. Make use of more than 200 system triggers to drive automation.
Workflow and approvals
Enforce change processes in real time. Model complex approval processes with flexible rules. Force approvals for changes, including changes made by a direct command-line interface session. Combine multiple tasks into a project workflow to determine whether the system should proceed to the next step.
High availability and satellite deployments
Implement high availability and disaster-recovery solutions with the high availability and satellite deployments. Administrators can effectively manage geographically dispersed networks without a single point of failure. Satellites help deal with devices located behind a firewall or handle overlapping IP address situations.
The horizontal scalability feature offers you added flexibility in how you can grow capacity while controlling software and hardware costs.
NCM uses a browser-based GUI and as such does not require any dedicated client software. The GUI is highly intuitive and responsive, so you can accomplish tasks quickly and efficiently.
