This policy establishes the rules to protect your company's network—its digital front door—from cyber threats. It provides a framework for securing your firewalls, Wi-Fi, VPNs, and cloud connections to prevent unauthorized access and protect your data.
-
Secure Your Internet Connection: Implement and maintain strong firewall rules to block malicious traffic and protect your internal systems from external threats.
-
Protect Your Wi-Fi Network: Enforce strong encryption and create separate, isolated guest networks to keep visitors and unmanaged devices away from your sensitive data.
-
Enable Safe Remote Access: Define secure requirements for VPN and other remote connections, ensuring employees can work from anywhere without compromising security.
-
Prevent Malware from Spreading: Use network segmentation to contain threats and stop malware from moving laterally across your internal network if a device is compromised.
Read Full Overview
The Network Security Policy - SME provides a comprehensive framework to safeguard small and medium enterprises' networks from unauthorized access, data breaches, and service disruptions. By implementing layered security controls such as segmentation, firewall enforcement, and secure routing, this policy ensures the integrity and confidentiality of data transmitted across both internal and external networks. A key feature of this policy is its alignment with international standards and regulatory requirements, including ISO/IEC 27001:2022, NIST SP 800-53, GDPR, NIS2, and DORA. This alignment not only aids in achieving compliance but also provides assurance to clients and auditors that the enterprise is committed to maintaining high security standards. Implementing the Network Security Policy - SME brings clarity and confidence to your cybersecurity strategy, enabling your organization to focus on growth without compromising on security.

About This Policy
A Network Security Policy is a foundational document that defines the rules and configurations for an organization’s computer networks to protect them from unauthorized access and cyber threats. For a Small or Medium-sized Enterprise (SME), where the network is the backbone of all digital operations, this policy establishes essential controls for firewalls, Wi-Fi access, remote connections (VPNs), and cloud services.
This policy provides a structured approach to network defense, including key practices like network segmentation, which limits the spread of malware in case of a breach. It mandates the use of strong encryption for all wireless traffic and remote access, and requires continuous monitoring and logging of network activity to detect and respond to incidents quickly. By implementing this ISO 27001:2022-aligned policy, your SME can build a resilient and secure network, demonstrate compliance with regulations like NIS2 and DORA, and give you confidence that your digital perimeter is protected.
