How does a NOC ensure cybersecurity?

A NOC ensures cybersecurity by proactively monitoring network infrastructure to detect threats early and minimize downtime. Using specialized tools, NOC technicians oversee network devices, servers, and firewalls to maintain visibility and prevent vulnerabilities. In collaboration with SOC teams, the NOC swiftly resolves incidents to protect business operations.

Operating as a centralized hub, the NOC streamlines monitoring and management while implementing best practices such as firewall configurations and intrusion detection systems. Regular updates and testing ensure the network stays secure against emerging threats. Organizations can enhance their cybersecurity by outsourcing NOC services to expert providers, gaining access to advanced tools and skilled personnel while reducing operational costs.

Think of NOC and SOC teams as your company's security guards and maintenance crew working together to prevent $4.45 million disasters, according to IBM Security. 

What is the difference between a NOC and a SOC?

A NOC and a Security Operations Center (SOC) are both centralized facilities, but they serve distinct purposes in an organization's IT infrastructure. 

Focus and Purpose:

• The NOC focuses on monitoring and managing network performance to ensure optimal uptime and reliability. It handles issues like network connectivity, server health, and network failures to prevent downtime. 
• The SOC, on the other hand, is dedicated to protecting an organization’s network from cyber threats. It monitors security events, detects vulnerabilities, and implements incident response to safeguard against breaches. 

Roles and Functions:
