DEMO Network Security Template

Purpose

This policy outlines how we secure and monitor network systems to protect SOC infrastructure from unauthorized access and cyber threats.

Scope

Applies to all SOC staff and covers routers, switches, firewalls, VPNs, wireless, and all network segments.

Policy Rules Network Access Control

Only authorized personnel may access network devices, and access is limited to job role needs.

Secure Configuration Requirements

All network devices must use secure configurations (no defaults, encrypted management, disabled unused ports).

Firewall and Traffic Control

Firewalls must block all traffic by default and only allow approved ports, protocols, and IP ranges.

Network Monitoring

The SOC must continuously monitor network traffic, logs, and alerts for suspicious activity.

Network Segmentation

Critical systems must be isolated using VLANs or segmented networks, with filtered and logged traffic.

Remote Access Rules

Remote access to network equipment requires VPN, encryption, MFA, and approved devices only.

Logging and Monitoring

All network logins, configuration changes, VPN activity, and security events must be logged and reviewed.

Reviewing Network Security

Network security settings and firewall rules must be reviewed at least every 6 months.

Handling Unauthorized Access

Unauthorized network access triggers immediate access removal, investigation, and documentation.

Consequences for Violations

Violations may result in loss of access or academic/disciplinary action.

Exceptions

Any exceptions must be documented, justified, and approved by SOC management.

Policy Updates

This policy is reviewed annually or when major network changes occur.
