What to include in a network disaster recovery plan checklist

A network disaster recovery plan should include components like documentation, emergency contacts, step-by-step procedures, provider and vendor details, backup info and more.

A network disaster recovery plan outlines procedures and policies network teams can follow when a crisis disrupts network services.

The complexity of a network DR plan varies based largely on the network configuration. The keys to a successful plan include understanding network risks and vulnerabilities, defining step-by-step response and recovery procedures, validating these activities through tests and keeping the plan updated.

Factors to include in a network DR plan

When building or updating a network DR plan, network pros must address several issues. Below are some essential factors and questions to consider.

Network configuration

If network architects have diagrammed the network, is the diagram current? Does it reflect any changes in technology, vendor or configuration?

Risk assessments

When did teams perform the last network risk assessment? Did they assess physical and logical network elements? Did they also evaluate network perimeter security?

DR plans

What DR plans are in place? When were they last reviewed and tested?

Local access networks

What is the status of local access resources? Does this access represent a critical single point of failure?


Does the LAN have redundancy built into its structure? Is the cabling safe? Are routers, hubs and switches survivable and housed in secure areas? What inventory of spare LAN components is available?

The complexity of a network DR plan varies based largely on the network configuration.


How redundant are the network links? What happens if a channel fails? What recourse is available if carriers don't provide facility recovery?

Internet access

How secure and survivable are the ISPs in use? How will they recover internet access if it goes down?

Premises-based PBX systems

Assuming the local phone system uses VoIP technology, what DR support does the vendor provide? What inventory of spare parts is available in case of a failure?

Emergency power systems

In addition to commercial power, what backup power resources are available? Is there enough backup power to run a VoIP system, LAN or WAN? How much backup power do carriers have available in an emergency?

Perimeter security

How secure is the network perimeter from unauthorized access via malware, ransomware, phishing, DDoS attacks and other malicious events? What emergency resources are available to recover network integrity? How is encryption used to protect the network and critical data? How often are firewall rules updated?

Network software

What backup copies of network security software are available? Where are backup copies of VoIP system software located? Are they up to date?

Wireless networks

What backup and recovery assets are in place to recover wireless network resources? What DR services are available from wireless carriers?

These are among the initial questions to ask when embarking on a network DR planning initiative. This graphic identifies the different risk points in current networks. Network teams must address each factor in a network DR plan, assuming all are used.

Depending on the size and complexity of a corporate network, teams can identify many different risk points -- or single points of failure. Identifying each of the risk areas in a network infrastructure is one of the most critical initial activities when preparing a network DR plan.

Strategies and challenges for DR planning

DR plans are essential to protect critical network infrastructure and associated assets. Teams should address the following strategies and challenges when building network DR plans:

  • Run risk assessments of all network assets.
  • Consider relevant DR standards for guidance.
  • Document policies and procedures for DR activities.
  • Assess primary and alternate suppliers, such as ISPs, wireless carriers, local exchange carriers and managed network service providers -- e.g., cloud vendors.
  • Evaluate diversely routed network configurations, both local access and wide area.
  • Conduct inventory of spare parts, including backup copies of network software.
  • Review network perimeter protective mechanisms.
  • Check backup power systems to see if they're properly sized for the applications or for environmentally safe power alternatives.
  • Assess commercial power systems, with an emphasis on diverse routing for power feeds.
  • Check power protection, including surge protection, lightning protection and grounding.
  • Secure physical space for housing network devices and cabling.
  • Assess whether HVAC systems provide a suitable environment for network equipment.
  • Test DR plans periodically to ensure backup resources work properly.
  • Review and maintain DR resources regularly.
  • Confirm access to emergency communications if primary service is unavailable.
  • Train network teams in DR procedures.

Create a network DR plan process in 16 steps

The network DR planning process contains several steps, usually in the following sequence:

  1. Initiate the project, and secure management approval and budget.
  2. Establish a network DR team.
  3. Compile network-related documents, including DR plans, procedures, drawings, equipment inventory lists, prior test reports and previous audit reports.
  4. Run a risk assessment of all relevant network risk points.
  5. Conduct a business impact analysis to evaluate what happens if network resources are unavailable.
  6. Develop a network DR policy.
  7. Develop a strategy, as noted in the previous section.
  8. Document project management activities.
  9. Develop the plan with incident-specific procedures.
  10. Test the plan, and update based on test results.
  11. Train network teams and employees, and ensure they're aware of necessary steps.
  12. Document emergency communications, such as wireless and emergency notification.
  13. Conduct plan reviews, assessments and audits.
  14. Coordinate with equipment and software vendors.
  15. Coordinate with local, WAN, wireless and managed service providers, such as cloud providers and ISPs.
  16. Coordinate with power utility companies.

Tips on network DR planning

The following are some important points to consider when developing a new network DR plan or updating an existing one.

1. Take the process seriously

A plan is essential for protecting network infrastructure and related assets from disruptive events. It doesn't have to be hundreds of pages long. However, it must have the right information, which should be current and accurate. Single- or two-page plans with the right information are more valuable than a huge document nobody will use in an emergency.

2. Look at existing templates

Many sources offer plan templates and guidance for disaster recovery and business continuity (BC).

3. Pay attention to standards

Standards can be helpful in structuring a plan and ensuring the right components are included. Consider the following U.S. standards from NIST:

  • NIST Special Publication (SP) 800-14 -- Generally accepted principles and practices for securing IT systems
  • NIST SP 800-24 -- PBX vulnerability analysis
  • NIST SP 800-34 -- Contingency planning guide for federal information systems
  • NIST SP 800-58 -- Security considerations for VoIP systems
  • NIST SP 800-94 -- Guide to intrusion detection and intrusion prevention systems

International standards from ISO include the following:

  • ISO 22301:2019 -- Security and resilience -- BC management systems -- Requirements
  • ISO/IEC 27031:2011 -- IT -- Security techniques -- Guidelines for information and communication technology readiness for BC

4. Keep the planning process and plan simple

If possible, err on the side of simplicity unless the network infrastructure is highly complex.

5. Use provider resources

Enterprises often use third-party service providers, owing to network complexity. Take advantage of the DR resources available from carriers and MSPs, including cloud vendors.

6. Limit plan content to identified DR procedures

Develop a plan that addresses specific incidents and scenarios identified from results of risk assessments and business impact analyses.

7. Broaden plan content

Another option is to take an "all-hazards" approach to network outages, specifically responding to all kinds of network outages.

8. Launch and manage the program

Upon plan completion, perform an exercise to validate the procedures, technology and carrier responses. Establish a schedule of plan reviews, exercises and training.

9. Be adaptable

A single plan may not apply to all networks in use. This step may be especially important when a network serves multiple corporate locations and data centers. Different plans may be needed for LANs, WANs, VoIP systems, wireless and other specialized networks.

10. Consider other resources

Multiple BCDR planning tools are available, as are many managed network service providers and consultants experienced in network DR.
