Starting with PAN-OS 10.0, TLS 1.3 decryption support has been added in all modes: Forward Proxy, Inbound inspection, Decryption mirror and Decryption broker. Remember to follow these 6 best practices for SSL Decryption: Determine the sensitive traffic that must not be decrypted Add exclusions to bypass decryption for special circumstances Set up verification for certificate revocation Configure strong cipher suites and SSL protocol versions By enabling decryption on your next-gen firewalls you can inspect and control SSL/TLS and SSH traffic so that you can detect and prevent threats that would otherwise remain hidden in encrypted traffic. I believe S4B MAY have an option to skip cert validation, but you'll of course want to make sure your security posture can/will tolerate that. Decryption Best Practices Version 9.1 You can't defend against threats you can't see. Set goals. Get our 10 Best Practices for SSL Decryption guide today to see how you can: Determine what traffic you need to decrypt; Create decryption profiles to improve performance; Use URL filtering to minimize risk; Find out how you can effectively adopt SSL decryption. 2019 Cost of a Data Breach Report, Ponemon Institute. The best practice Decryption profile settings for the data center and for the perimeter ( internet gateway) use cases differ slightly from the general best practice settings. Plan Your SSL Decryption Best Practice Deployment Previous Next Prepare to deploy decryption by developing a decryption strategy and roll-out plan. SSL Decryption Best Practices Deep Dive. Turning on decryption may change the way users interact with some applications and websites, so planning, testing, and user education are critical to a successful deployment. 1.
