1. Which software blades support HTTPS Inspection?
   

   • Awarding Control
   • URL Filtering
   • IPS
   • Data Loss Prevention (DLP)
   • Anti-Virus
   • Anti-Bot
   • Threat Emulation
   • Content Awareness

2. Which operating systems support HTTPS Inspection?
   

   HTTPS Inspection is supported on Security Gateways running only Gaia OS and SecurePlatform Os. Also see Question 22 (re: GAiA Embedded).

3. Does HTTPS Inspection require a license? Is it a software bract?
   

   HTTPS Inspection is not a blade and does not crave a license. It is included complimentary of charge with other blades.

4. Are there legal implications to enabling HTTPS Inspection in my system?
   

   There may be privacy and legal regulations on the apply of this feature depending on the country in which you are located. Please review your local laws and regulations.

5. Has Check Betoken cracked HTTPS? Could an aggressor do this?
   

   Bank check Betoken has not cracked HTTPS or SSL. HTTPS is regarded as secure and is non known to take been cracked.

   For HTTPS traffic inspection, Security Gateways must examine the data every bit clear text. Encrypted data sent by a client to a web server is:

   1. Intercepted by the Security Gateway and decrypted.
   2. Inspected past the blades divers by the policy.
   3. Encrypted again and sent to the designated web server.

   The Security Gateway acts as an intermediary between the client computer and the secure web site.
   The Security Gateway behaves as the client with the server, and as the server with the client using certificates.

6. Why do I get certificate warnings in the browser after turning on HTTPS Inspection?
   

   A dedicated CA signs certificates, and the Security Gateway presents these certificates to the client.
   Before the user installs that CA certificate, any site accessed past the browser will produce warnings.

7. How tin I make PCs trust the gateway's CA certificate?
   

   To make the PC trust the gateway CA document:

   1. Export the CA document from the SmartDashboard (on the HTTPS Inspection window of the Security Gateway, or on the HTTPS Inspection > Gateways pane).

   2. Install the certificate on the user's PC:

      Manually put the certificate file in the user's PC. Click the file and follow the magician instructions to add the certificate to the trusted root certificates repository on client machines.

      Apply GPO or group policy to distribute the certificate to a large group of users. Encounter the documentation for more details.

8. Does HTTPS Inspection use the Security Management server'south Internal CA to issue certificates?
   

   No. HTTPS Inspection uses a dedicated CA.

9. Is there a operation touch on when enabling HTTPS Inspection on the gateway?
   

   HTTPS Inspection requires the Security Gateway to perform extra SSL work:

   • SSL handshake with the secure web site and with the client browser.
   • Decrypt & re-encrypt all SSL traffic, to exist able to inspect information technology.

   
   This has some performance impact on SSL capacity and latency, but in normal situations the end user should not be aware of it.

10. Why are Extended Validation (EV) certificates displayed as regular certificates in the browser?
    

    When HTTPS Inspection is used, the browser sees server certificates, signed by the gateway, rather than by the original trusted CA. To get the EV indication in the browser, the server certificate must be signed by a specially-designated Certificate Authority. The listing of those CA certificates is hard-coded into the browser, and cannot be modified by the user.

11. How are the CAs in the listing of Trusted CAs chosen? Is the list updated?
    

    The listing of certificate authorities is taken from the Windows organisation stores. It is updated according to Microsoft updates.

12. Does HTTPS Inspection check for CRLs? What about OCSP?
    

    Yes. By default, the CRL cheque is washed on the certificate.
    The check is done without holding the connection, and so the kickoff time a user accesses a specific site, it volition laissez passer without CRL validation, and the next connexion will be validated.
    By default, if the CRL can't be reached, the certificate is considered to be trusted (this is also the default beliefs of the mutual browsers).

    If y'all wish to enforce CRL fetch, and to mark the certificate as untrusted, if the CRL can non be reached, y'all can use GuiDBedit Tool to alter the value of aspect " drop_if_crl_cannot_be_reached " to " true " (Tables -> "Other" -> "SSL Inspection" table -> "general_confs_obj" Object).

    OCSP is supported from R80.10 and from Jumbo Hotfix Accumulator for R77.30 (Take 266).

13. Does HTTPS Inspection work on protocols other than HTTPs?
    

    No, currently it is simply possible to inspect HTTPS traffic.

14. Can I replace the gateway's CA with a different CA?
    

    Yep, yous can import any CA document to exist used for HTTPS Inspection.

    To import a CA certificate (refer to sk108641):

    In R7x SmartDashboard:

    1. Connect with SmartDashboard to Security Management Server / Domain Management Server.
    2. Go to Application & URL Filtering tab - on the left, open Advanced - open HTTPS Inspection - click Gateways.
    3. In the CA Document department, click the Renew Certificate button - click Import certificate from file... (if no certificate is created yet, click Create first).
    4. The file to import must be a p12 file containing self-signed CA or subordinate CA.

    In R8x SmartConsole:

    1. Connect with SmartConsole to Security Direction Server / Domain Management Server.

    2. Get to the list of Security Gateways with enabled HTTPS Inspection:

       1. Open up HTTPS Inspection configuration in the Legacy SmartDashboard (select any of these options):

          • On the left Navigation Toolbar, click the MANAGE & SETTINGS - in the upper pane, click on the Blades - in the middle pane, scroll down to the HTTPS Inspection department - click the link Configure in SmartDashboard...:

          • On the left Navigation Toolbar, click the SECURITY POLICIES - in the left pane, in the Shared Policies section, click the HTTPS Inspection - in the middle pane, click the link Open HTTPS Inspection Policy in SmartDashboard...:

       2. In Legacy SmartDashboard, go to the HTTPS Inspection tab - in the left tree, click the Gateways:

    3. In the lower CA Certificate section, click on the Renew Certificate button - cull the desired pick:

       • Renew Certificate...

       • Import Certificate from file...

    4. In the lower CA Certificate section, click on the Consign... button and save the certificate.

       Install this certificate as a valid Root CA on host computers in your arrangement (refer to the relevant documentation for the operating organization on those computers - e.grand., for Windows Bone, refer to Microsoft documentation).

    You can likewise import a document signed past hash algorithm SHA-256.

15. Is it possible to perform selective inspection - just on specific sites, categories or users?
    

    Yes, you tin can inspect merely specific sites or URL Filtering categories (both require a URL Filtering Blade license).

16. Why do I sometimes go the gateway CA even for sites that are not configured to be decrypted?
    

    To filter out sites from HTTPS Inspection, a mapping betwixt the site IP to its correlating domain is needed. The mapping is created based on the certificate DN served by the site. This requires u.s. to perform HTTPS Inspection on any accessed SSL site, at to the lowest degree once. After this mapping is in place, no further inspection will occur (according to the Rule Base). -- This is the underlying reason for the "refresh" success.
    Note: This behavior is merely relevant if there is no proxy betwixt the gateway and the Cyberspace. If there is a proxy, we don't perform full inspection.

17. What information from the encrypted traffic is logged?
    

    No additional data is logged aside from the regular data logged per Blade. The ambassador must have special permissions to view this information.

18. I read in the news that someone conned the "xyz" CA to requite them certificates for the "abc" web site. What should I practice?
    

    It is possible to apply the GUI to remove the victim CA from the listing of trusted roots. Simply this is not recommended, as it would damage connections to other customers of that CA.

    Some other selection is to add the specific certificate serial number to the Black List on the SmartDashboard.
    This approach has been successfully used by all browser vendors in March 2011, when Comodo was conned into issuing multiple certificates for pop web sites.

    Check Indicate will publish regular updates to the listing of CAs, and in the future also to the black-list of known stolen certificates.

19. Which SSL/TLS versions are supported past HTTPS Inspection?
    

    SSLv3 and TLSv1 (also known as SSLv3.1). Too, TLSv1.1 and TLSv1.ii.
    TLS 1.3 traffic is supported in R81 in USFW.

20. Why isn't SSLv2 supported?
    
21. Which ciphers are supported by SSL inspection?
    
22. On which platforms/appliances is HTTPS Inspection supported?
    

    For Gaia Embedded:

    • HTTPS Inspection is supported in both locally and centrally managed appliances on all platforms deployed with R8x based firmware (1500 series and college).
    • On Centrally managed 1100 / 1200R / 1400 HTTPS inspection is supported in R77.20-based firmware.
    • On Locally managed 700 / 900 / 1400 series HTTPS inspection is supported since R77.20.70.

    HTTPS Inspection is not supported on Windows OS.

23. Does HTTPS Inspection back up 3rd political party wildcard certificates (like *.mycompany.com)?
    
24. Why after enabling HTTPS Inspection some resources that use HTTPS protocol fail to connect?
    
25. Is Client Document authentication supported by HTTPS Inspection?
