If you find yourself in a situation where turning off the Fortinet Firewall is not feasible or desirable, consider implementing additional security measures to address specific requirements or concerns. These alternative security measures can supplement the firewall's protection and ensure the integrity of your network:

1. Intrusion Detection and Prevention Systems (IDPS)

An IDPS monitors network traffic, identifies unusual or suspicious activities, and takes action to prevent potential attacks. It complements the firewall by offering real-time threat detection and response capabilities. By deploying an IDPS, you can detect and block malicious traffic even when the firewall is active.

Some key features of an IDPS include:

• Advanced threat detection through behavioral analysis and anomaly detection.
• Active response mechanisms like blocking certain traffic or isolating compromised devices.
• Continuous monitoring and network traffic analysis.
• Integration with security information and event management (SIEM) systems for centralized reporting and analysis.

Implementing an IDPS as an additional security layer can help compensate for the absence of the Fortinet Firewall while offering enhanced threat detection and response capabilities.

2. Network Segmentation

Network segmentation involves dividing your network into smaller, isolated segments based on factors like departments, functions, or security requirements. By doing so, you limit the impact of a potential security breach and improve control over network traffic. It serves as a risk mitigation strategy, reducing the likelihood of unauthorized lateral movement within the network.

Key benefits of network segmentation include:

• Limited exposure: Compartmentalizing your network reduces the potential attack surface by restricting access to sensitive data and critical systems.
• Granular access control: Network segmentation allows you to apply specific security policies for each segment, ensuring appropriate permissions and minimizing the impact of any security incidents.
• Improved network performance: By reducing the broadcast domain, network segmentation helps enhance network performance and bandwidth utilization.

Implementing proper network segmentation provides an additional layer of protection and control, helping mitigate the risk associated with disabling the Fortinet Firewall.

3. User and Entity Behavior Analytics (UEBA)

UEBA is an advanced security technology that uses machine learning algorithms to monitor and analyze user and entity behavior within your network. It establishes baselines of normal behavior and identifies anomalous activities that may indicate a potential security breach or unauthorized access.

Key features of UEBA include:

• Real-time behavior analysis: UEBA continuously monitors user activities, network traffic, and access patterns to identify deviations from normal behavior.
• Threat detection and response: By detecting suspicious behavior, UEBA triggers alerts or initiates automated actions to mitigate potential threats and minimize the impact of security incidents.
• Risk scoring: UEBA assigns risk scores to individuals or entities based on their behavior, allowing security teams to prioritize their investigations and response efforts.
• Integration with other security tools: UEBA can integrate with existing security solutions, such as SIEM and IDPS, to provide comprehensive visibility and response capabilities.

Implementing UEBA can bolster your network security by detecting and responding to threats in real-time, compensating for the absence of the Fortinet Firewall.
