SOC vs NOC: Security Operations Centre vs Network Operations Centre

In modern organisations, Security Operations Centres (SOC) and Network Operations Centres (NOC) play distinct yet complementary roles. Both are critical in maintaining the functionality, security, and reliability of an organisation’s IT infrastructure.

However, while they share certain similarities, they focus on different aspects of operations. The SOC is primarily concerned with cybersecurity, while the NOC focuses on network performance and uptime.

This blog by White Label Service Desk explains the unique roles, core functions, and key differences between SOC vs NOC, and how they work together to form a holistic approach to IT infrastructure and security management.

What is a Security Operations Centre (SOC)?

A Security Operations Centre (SOC) is a centralised team responsible for monitoring, detecting, analysing, and responding to cybersecurity threats within an organisation. SOCs are staffed with security analysts, incident responders, and other cybersecurity professionals who focus on protecting the organisation’s digital assets from cyber threats.

Core Functions of a SOC

Threat Detection: SOC analysts continuously monitor for signs of cyber threats, such as malware, ransomware, phishing attempts, and unauthorised access.
Incident Response: SOC teams manage incidents by investigating, containing, and resolving cybersecurity breaches as they occur.
Vulnerability Management: SOC teams identify vulnerabilities in the system and recommend mitigation steps to protect against future threats.
Security Policy Enforcement: Ensures compliance with organisational security policies, industry standards, and regulatory requirements.
Forensic Analysis: When a security incident occurs, SOC teams conduct forensic investigations to understand its root cause and prevent similar incidents.

SOC Goals and Objectives

The primary goal of a SOC is to secure an organisation’s IT environment against cyber threats. This involves proactive monitoring, rapid response to incidents, and minimising damage from breaches. SOC teams work to ensure data integrity, confidentiality, and compliance with cybersecurity regulations.

Example Use Case for SOC

If an organisation experiences a phishing attack targeting employee credentials, the SOC team would detect the threat, alert affected users, and isolate any compromised systems to prevent further impact.

What is a Network Operations Centre (NOC)?

A Network Operations Centre (NOC) is a centralised team responsible for ensuring the stability, performance, and uptime of an organisation’s network infrastructure. NOC staff monitor network devices, servers, databases, and applications to detect and resolve issues that could disrupt network availability.

Core Functions of a NOC

Network Monitoring: Continuously tracks network health, performance, and bandwidth to ensure all systems are operational.
Troubleshooting and Issue Resolution: Identifies, diagnoses, and resolves network-related issues before they impact users.
Performance Optimization: Ensures network performance is optimised by managing traffic, load balancing, and system configurations.
Incident Management: Addresses network outages, system crashes, and other disruptions to ensure minimal downtime.
Infrastructure Maintenance: Regularly updates network hardware, applies patches, and manages firmware upgrades to maintain reliability.

NOC Goals and Objectives

The NOC’s main objective is to maintain network performance, optimize uptime, and ensure connectivity across all IT systems. The NOC team focuses on troubleshooting network issues quickly to prevent downtime that could impact business operations.

Example Use Case for NOC

If there’s a network outage affecting internet connectivity for an organization, the NOC team would identify the root cause, restore connectivity, and work to prevent future outages.

Key Differences: SOC vs NOC

While SOC and NOC teams are both essential for IT operations, they have distinct roles, tools, and objectives.

These differences underscore the unique but complementary roles that SOC and NOC play within an organisation. SOC focuses on security, while NOC ensures operational continuity.

Key Responsibilities and Roles in SOC and NOC Teams

SOC Team Roles and Responsibilities

Security Analyst: Monitors systems for suspicious activities, conducts initial threat investigations, and escalates incidents.
Incident Responder: Leads efforts to contain, analyse, and remediate security incidents.
SOC Manager: Oversees SOC operations, ensures compliance with policies, and coordinates with other departments.
Forensic Specialist: Investigates breaches, identifies root causes, and provides insights for preventive measures.

NOC Team Roles and Responsibilities

Network Engineer: Manages network configurations, monitors performance, and resolves connectivity issues.
NOC Technician: Conducts real-time monitoring of network health, responds to alerts, and troubleshoots issues.
Infrastructure Specialist: Maintains hardware and network infrastructure, performs updates, and optimizes performance.
NOC Manager: Oversees NOC operations, manages incident escalations, and collaborates with IT and SOC teams.

These roles highlight how the SOC and NOC teams bring specialized expertise to their respective domains, ensuring a well-rounded approach to IT management.

How SOC and NOC Work Together

While SOC and NOC teams have different focuses, their collaboration is essential for comprehensive IT management. Both teams benefit from sharing insights and coordinating efforts to address both security and network issues effectively.

1. Shared Monitoring and Incident Response

If a security breach affects network performance, both SOC and NOC teams are alerted. While the SOC team focuses on isolating and investigating the breach, the NOC team addresses any network disruptions.

2. Data Sharing for Improved Security and Performance

The SOC team can use network performance data from the NOC to identify unusual traffic patterns that may indicate a potential threat. Similarly, the NOC can use SOC insights to understand if certain security measures may be impacting network performance.

3. Joint Crisis Management

In a large-scale incident, such as a Distributed Denial of Service (DDoS) attack, both SOC and NOC teams collaborate. The SOC team works to identify and mitigate the attack, while the NOC team focuses on maintaining network stability.

4. Enhanced Threat Intelligence

By combining the SOC’s cybersecurity insights with the NOC’s network data, organizations can develop more comprehensive threat intelligence, enabling faster detection and response to emerging threats.

Key Tools Used in SOC and NOC

SOC Tools

SIEM (Security Information and Event Management): Aggregates and analyses security data to detect and respond to threats.
Intrusion Detection and Prevention Systems (IDS/IPS): Monitors for suspicious activities and prevents unauthorized access.
Endpoint Detection and Response (EDR): Provides endpoint visibility and protection against malware and ransomware.
Threat Intelligence Platforms: Provides external data on emerging threats and attack methods.

NOC Tools

Network Monitoring Tools (e.g., SolarWinds, PRTG): Tracks network performance, bandwidth, and uptime.
Simple Network Management Protocol (SNMP): Collects network device data to monitor health and performance.
Traffic Analysis Tools: Analyzes network traffic for optimization and identifies congestion issues.
Performance Management Tools: Monitors key metrics like latency, packet loss, and bandwidth utilization.

Choosing Between NOC vs SOC, or Both for Your Organisation

When deciding whether to implement a SOC, NOC, or both, consider the specific needs and scale of your organisation:

Choose a SOC if:

- Cybersecurity is a top priority due to the sensitive nature of your data.
- Your industry faces stringent compliance requirements (e.g., healthcare, finance).
- You experience frequent cyber threats and require dedicated threat monitoring and response.

Choose a NOC if:

- - Network uptime and performance are critical to your operations.
