The Software Vulnerability Conundrum:
Many individuals question whether refurbished network equipment poses a risk due to software vulnerabilities. The unequivocal answer is that any network equipment lacking the latest security patches or failing to implement appropriate security measures is susceptible to software vulnerabilities.
Pentacraft Innovate's Approach:
Pentacraft Innovate understands the importance of balancing security with practicality. While some may suggest air-gapping switch management to enhance security, Pentacraft Innovate advocates for a more nuanced approach. The use of a firewall, specifically the Fortinet Fortigate firewall, emerges as a key component in Pentacraft Innovate's strategy.
Why Fortinet Fortigate Firewall?
Gartner Magic Quadrant Leader: Fortinet Fortigate firewall stands out as a leader in the Gartner Magic Quadrant, reflecting its strong brand reputation and reliability.
High Switching Performance: With superior switching performance compared to competitors in the same Gartner Magic Quadrant, Fortigate firewall ensures optimal network functionality.
Affordability: Fortinet Fortigate firewall provides excellent value for money, making it accessible to companies of all sizes, from small startups to large enterprises.
Free Fortitoken Soft Mobile Tokens: Fortigate offers 2x Fortitoken soft mobile tokens for free, facilitating easy implementation of 2FA for IT departments, enhancing overall network security.
Captive Portal Functionality: The firewall's captive portal function enables 2FA authentication for user network access, fostering a secure environment. Integration with radius servers allows for Single Sign-On (SSO).
User Profile Integration: Fortigate firewall allows user profiles to be added to firewall rules, ensuring authorized users match the specified rules before allowing traffic to pass through.
Securing Switch Management - A Step-by-Step Guide:
Create VLAN for Switch Management: Assign an IP address to the Cisco Catalyst layer2 switch for switch management.
Fortigate Firewall Configuration: Set up a physical interface or sub-interface on the Fortigate firewall with an IP address in the same VLAN and subnet as the switch management IP.
Configure Default IP Gateway: Set the default IP gateway on the Cisco switch to the new switch management interface on the Fortigate firewall.
User Profile and 2FA: Create a user profile on Fortigate firewall and assign the free 2FA Fortitoken. Establish user groups to streamline management.
Create User VLANs: Implement user VLANs (wired and wireless) on the Cisco switch and firewall interface, ensuring all user traffic passes through the Fortigate firewall.
Enable Captive Portal: Enable captive portal and firewall interfaces, designating them as default gateways for wired and wireless users.
Create Firewall Rules: Develop firewall rules specifying source and destination IPs, interfaces, allowed protocols/ports, and security profiles (IPS/Application Control). Ensure authorized user or user group profiles are integrated into the rules.
Secure Access and Traceability:
Each time an IT professional needs to access switch management, they must provide a username, password, and 2FA for authentication. With user-based firewall rules, all firewall logs will contain user IDs, facilitating easy traceability of access and enabling proactive threat hunting.
Conclusion:
Pentacraft Innovate's approach provides a robust and comprehensive solution to secure switch management, minimizing the residual risk associated with software vulnerabilities. By combining Fortinet Fortigate firewall's advanced features with meticulous configuration steps, Pentacraft Innovate offers a secure and efficient environment for IT professionals. Implementing these measures not only enhances security but also allows for streamlined network management and threat tracing. Secure your network environment with Pentacraft Innovate's innovative approach – safeguarding your data, users, and peace of mind.
