Mitigation Strategies Using Fortinet Products

Organizations using the SourceCodester Product Review Rating System should prioritize patching the software to the latest secure version as recommended by the vendor. In addition, deploying a robust security infrastructure is critical. Here’s how Fortinet products can help mitigate this vulnerability:

• FortiWeb: FortiWeb web application firewall (WAF) can detect and block XSS attacks in real time. By configuring FortiWeb to monitor and sanitize input fields, particularly those for 'Your Name/Comment', you can effectively prevent malicious scripts from being executed. Use the following configuration commands to enable XSS protection:

config webfilter profile
edit [profile_name]
set xss-protection enable
set xss-cross-site-scripting enable
end

• FortiGate: FortiGate firewalls offer integrated web filtering features that can block XSS payloads. By enabling DLP (Data Loss Prevention) signatures tailored to detect XSS patterns, FortiGate adds an extra layer of security. Configure your FortiGate for XSS protection using:

config ips sensor
edit [sensor_name]
config entries
edit 1
set action block
set log enable
set signature-id [signature_id_for_XSS]
end
end

• FortiSandbox: For advanced threat detection, FortiSandbox can be used to analyze suspicious inputs in a controlled environment, identifying potential XSS scripts before they impact live systems.
