Inline SSL Policy Profile—Field References

The following table lists and describes the attributes that define the Inline SSL Policy Profile.

Field	Description
Alias	Enter a unique name for the flexible inline SSL APP.
Policy Configuration
SSL Monitor Mode	Select an SSL Monitor Mode from one of the following options: ■   Enable—When the monitor mode is enabled, the SSL decryption or encryption is off. The monitor application collects information such as the TCP ports that are in use and VLAN information about the incoming traffic, and forwards the packets to the tool port or network port based on the non-SSL TCP bypass action. ■   Disable—This is the default value. When the monitor mode is disabled, the SSL decryption or encryption is on. Use this mode during the deployment stage. ■   Inline—Both monitor mode and SSL decryption or encryption is on. Use this mode to debug issues. Refer to Inline SSL Monitor Mode for details.
Default Action	Select one of the following option: ■   Decrypt—Decrypt all the traffic that is guided into the Inline SSL APP. ■   No Decrypt—Do not decrypt the traffic that is guided into the Inline SSL APP.
URL Cache Miss Action	Select one of the following options: ■   Decrypt—Decrypt all the traffic that is guided into the Inline SSL APP. ■   No Decrypt—Do not decrypt the traffic that is guided into the Inline SSL APP. ■   Defer—Delay the decryption until the Defer Timeout seconds provided.
Tool Fail Action	The failover action taken in response to a failure of an inline tool. Select one of the following options: ■   Bypass Tool—The traffic bypasses the failed inline tool. ■   Drop Connection—The traffic is dropped.
Decrypt Tool bypass	Bypasses the decrypted SSL traffic.
No Decrypt Tool bypass	Bypasses the non-decrypted SSL traffic.
Non-SSL TCP Traffic Tool bypass	Bypasses the non-SSL, that is the TCP intercepted traffic.
High Availability	Select the check box to detect the link switchover by upstream device that is in active or standby mode. Note:  Do not select this check box if the inline network links are in active state. Refer to High Availability Active Standby for details.
Network Group Multiple Entry	Select this check box to allow the traffic from different inline network to reenter GigaSMART. Refer to Inline Network Group Multiple Entry for details.
Tool Early Engage	Select this check box to allow the inline tools to change the MAC address or VLAN IDs. When a connection request is received from the client, GigaSMART establishes the connection with the inline tool first, before connecting with the server. This helps the inline tools to modify the MAC address or VLAN IDs when sending the traffic back to the server. Refer to Tool Early Engage for additional information and limitations.
One-Arm Mode	Select this check box to have both the client and server traffic travel through the same physical link or logical aggregate port channel. Refer to Tool Early Engage for additional information and limitations. Note:  You can enable the One-Arm mode only if you have enabled the Tool Early Engage option.
StartTLS Port	Enter the required SSL/TLS ports. Refer to StartTLS and HTTP CONNECT for details.
Security Exceptions	You can choose to either decrypt or drop the traffic for the following certificates: ■   Self-signed certificate ■   Unknown CA certificate ■   Invalid certificate ■   Expired certificate You can also choose to configure the security exceptions for certificate revocation validation based on OCSP or CRL on inline decryption profile. Select one of the following options: ■   Soft Fail—If you select this option, the client browser displays the secondary MitM certificate and the inline decryption session stats in GigaVUE‑FM displays as Decrypt. ■   Hard Fail—If you select this option, the client browser displays the certificate from DigiCert and the inline decryption session stats in GigaVUE‑FM displays as Bypass: Unknown Revocation. Refer to Certificate Revocation List (CRL), Online Certificate Status Protocol (OCSP), CRL and OCSP, and Checking Certificate Revocation Status for details.
No-decrypt list/Decrypt list	Select the following check boxes: ■   No-decrypt list—Allows traffic from certain classes such as sites, domains, host-based IP address and IP subnets (decision based on LPM) to bypass decryption. ■   Decrypt list—Allows traffic from certain sites, domains, host-based IP address and IP subnets (decision based on LPM) to always be decrypted. To update/append, download the existing whitelist/blacklist text file from GigaVUE-FMFM, add new entries, and upload. This will not remove the existing entries in the list. To replace the entire list, download the existing whitelist/blacklist text file from GigaVUE-FM, retain a copy, clear the list and upload a new whitelist/blacklist. Refer to No-decrypt Listing Policy and Decrypt Listing Policy for details.
Policy Rules	Add the required policy rules for the inline decryption profile.
TCP Port Map Decryption	The TCP destination port for decrypted traffic sent to inline tools can be configured as part of the inline decryption profile. Configure the required Priority 1 map, which is user configurable and Priority 2 map, which is the default out port. Refer to Inline SSL Decryption Port Map for details.
TCP Settings	Configure the required TCP settings as follows: ● TCP Inactive Timeout—TCP Inactive session timeout in minutes ● TCP Delayed ACK—GigaSMART Inline SSL decryption ACKs every TCP packet by default. If TCP Delayed ACK is enabled, then GigaSMART decryption will wait for 100ms or ACK every third packet – whichever comes first. ● TCP SYN Retries—number of retries made by the MitM to initiate a session with the destination server. If a SYN/ACK response isn't received from the destination server on initial TCP SYN, GigaSMART attempts for additional number of TCP SYN Retries as defined by the user.
Server Key Map	A server key map binds a server with a key pair alias.
Split-Proxy Settings
Split-Proxy	Select the check box to enable the split proxy settings for the inline decryption solution. The TLS connection between the server and client is divided into two independent connections and the security parameters are kept separate.
Non-PFS Ciphers (Server)	Select the check box to enable the non-PFS ciphers settings for the inline decryption solution that has the split proxy settings enabled. This setting is to indirectly force the server to use protocols that are lower than TLS1.3 with non-PFS ciphers. This means that the ciphers with DHE/ECDHE key-exchange will not be used on the server side.
