Network Management

Network Discovery, Auditing, and Compliance: A Complete Guide

Sarah Lispet· 2024-11-14

The networking landscape of the future will be more complex to navigate than ever before. "The global cost of cybercrime is estimated to reach 15.63 trillion U.S. dollars in 2029," following continuous increases over 16 years. Global data creation is expanding dramatically, and AI adoption is becoming unavoidable across organizations.

To maintain competitiveness and prevent business disruption, effective network management is essential. Taking proactive steps toward network compliance becomes increasingly critical. However, achieving effective network management requires knowing which assets exist on your network.

Network discovery and auditing play crucial roles in achieving compliance, strengthening security, increasing operational resilience, and ensuring business continuity. These processes create a Network Source of Truth (NSoT) -- a central data repository enabling effective management and configuration of entire networks.

What is network discovery?

Discovery serves as the foundation for achieving compliance and effective network management. It refers to identifying all devices and components connected to a business network, creating a comprehensive asset inventory including hardware devices, software applications, and services.

Network discovery typically involves running scripts (Python, PowerShell, or Bash) and sending ping requests, SNMP queries, or port scans to detect and examine network components. Teams collect data on device types, versions, connections, access controls, and usage patterns.

Regular network discovery enables several critical capabilities:

  • Achieve compliance: Regularly updated and recorded network inventories represent the first step toward maintaining regulatory compliance with industry standards.
  • Effectively allocate resources: Optimize network performance and costs by identifying underutilized resources and balancing allocation across the infrastructure.
  • Keep devices up to date: Ensure each network device has the latest software and versions to patch vulnerabilities and protect data comprehensively.
  • Asset management: Obtain comprehensive inventories of all network devices, applications, and services for improved tracking and management, including end-of-life hardware and both greenfield and brownfield devices.
  • Security monitoring: Identify unauthorized devices or unwanted user permissions through firewall service monitoring and Windows security dashboards, enhancing network security.
  • Troubleshooting: With detailed network topology maps and connected device information, administrators can more easily diagnose, resolve, and prevent network issues.

Network discovery equips IT professionals with comprehensive understanding of network infrastructure, enabling more effective management, security, and optimization.

What is network auditing?

While discovery identifies what exists on networks, auditing evaluates and assesses security, performance, and compliance. Teams filter discoveries using custom parameters to explore nearly any desired information.

Network audits produce reports for business records and track network changes over time. Discovery information generates various audit reports:

  • Asset inventory snapshot: Comprehensive lists of network-connected devices, systems, and assets including servers, routers, switches, printers, IoT devices, and workstations.
  • Network topology map: Visual representations showing how network devices connect to one another.
  • Device configuration: Detailed configuration information for firewalls, switches, and routers, tracking configuration changes over time.
  • Access control: User permissions and access levels across devices and software for managing internal threats.
  • Security vulnerabilities: Identification of outdated software, open ports, weak passwords, and insecure protocols like Telnet.
  • Traffic and bandwidth usage: Analysis of bandwidth distribution across network segments and identification of congestion points.
  • Compliance status report: Network compliance checks against standards including GDPR, HIPAA, PCI-DSS, ACSC Essential Eight, and CIS benchmarks.

Regular network audits are crucial for business continuity. They help organizations maintain secure, compliant infrastructure by identifying and addressing potential issues proactively, mitigating risks, preventing breaches, and avoiding costly downtime or penalties.

What is network compliance?

Network compliance means adhering to relevant regulations and standards maintaining data integrity, privacy, and security. Compliance is non-negotiable in network management, as customer, investor, and partner trust depends on meeting regulatory standards.

Organizations must remain vigilant about compliance to meet legal requirements, avoiding hefty fines and reputational damage. Applicable regulatory frameworks depend on industry and operational regions and typically include data security measures. Organizations may also enforce internal data privacy rules.

Businesses achieve compliance through discovery and auditing by:

  1. Identifying applicable regulations based on industry, location, and data handling practices.
  2. Conducting regular network audits identifying vulnerabilities and non-compliance areas according to regulations.
  3. Implementing security controls and fixes addressing identified risks and regulatory requirements.
  4. Continuously monitoring networks for compliance violations and security incidents.
  5. Producing compliance status reports checking against industry regulations and serving as compliance verification records.
  6. Maintaining detailed documentation and audit trails for change tracking and compliance audits.

How discovery, auditing, and compliance work together

Each process strengthens the others: discoveries provide visibility, audits assess security and compliance, and together they enable organizations to maintain compliance systematically and thoroughly. Network compliance relies on accurate discovery data ensuring precise audits and ongoing alignment with security policies.

Running network discoveries enables multiple audits from single discoveries for:

  • Storing compliance reports
  • Reviewing and fixing issues maintaining compliance
  • Checking against internal standards
  • Tracking changes over time
  • Focusing on specific network aspects like bandwidth distribution or hardware warranty status

Why discovery, auditing, and compliance matter

Trust hinges on regulatory compliance. Would customers trust healthcare providers without HIPAA compliance, utilities providers without NERC compliance, or banks without PCI DSS compliance? As networks grow more complex, discovery and auditing ultimately enable achieving both compliance and profitable business operations.

Every organization should take compliance seriously, as failure results in:

  • Costly regulatory fines
  • Legal liabilities including potential lawsuits
  • Long-term reputational damage
  • Increased government scrutiny
  • Interrupted business operations
  • Lost customer and investor trust

Broader consequences of ineffective network management include:

  • Cyberattacks from network vulnerabilities, outdated software, or unauthorized access
  • Escalating costs from unchecked network inefficiencies
  • Performance issues from limited visibility over usage patterns and bandwidth
  • Poor resource allocation causing bottlenecks and underutilized resources
  • Difficulty diagnosing and resolving issues, increasing mean time to resolution and causing downtime
  • Challenges managing and integrating networks as organizations add providers and locations

Manual discoveries and audits are error-prone, time-consuming, and inadvisable. Automating network discovery with tools provides businesses with a Network Source of Truth, allowing validation of network performance and complete management control. This generates time and resource savings, improves reliability, enables proactive issue resolution, reduces operational disruptions, minimizes downtime, and accelerates time to market.

Purpose-built tools enable automating and customizing network discoveries ensuring comprehensive coverage.

Discovery, auditing, and compliance tools

Effective network management requires tools integrating with networks, scanning devices, storing configurations, and generating insights for auditing and decision-making.
