Table 24 General communication preferences

Preference

Description

Communication

Sets the amount of time that ETEMS waits for a response from an appliance

timeout

during a standard communication attempt (refreshing status, comparing

 

configurations, loading configurations). The valid range is 1-180 seconds.

Software upgrade

Sets the amount of time that ETEMS allows for a software upgrade on an

timeout

appliance to complete. The valid range is 60-1,296,000 seconds (15 days).

Use TLS

By default, ETEMS uses TLS to encrypt communications between the

 

management workstation and the appliance’s management port. When TLS

 

is enabled, communication between ETEMS and the appliance is encrypted.

 

If you are managing ETEP appliances, TLS must be enabled. ETEMS

 

cannot communication with the ETEP when TLS is disabled.

 

 

Table 25

Strict authentication communication preferences

 

 

 

 

Use Strict Certificate

When enabled, all management communications between EncrypTight

Authentication

components is authenticated using certificates. EncrypTight can use TLS

 

 

with encryption only, or TLS with encryption and strict authentication for

 

 

added security. For more information about strict authentication, see “Using

 

 

Enhanced Security Features” on page 261.

Enable Online

When enabled, EncrypTight uses the online certificate status protocol

Certificate Status

(OCSP) to check the validity of certificates. OCSP is an alternative to using

Protocol (OCSP)

CRLs. For more information about OCSP, see “Validating Certificates Using

 

 

OCSP” on page 289.

OCSP Responder

Specifies the subject name of the certificate for the OCSP responder.

Certificate

 

 

Distinguished Name

 

Verify OCSP

Verifies OCSP responses by authenticating the response message with the

Responder

 

installed certificate. To use this option, you must install the certificate from

 

 

the OCSP responder.

Ignore Failure to

When checked, this option allows ETEMS to accept a certificate even when

Respond

 

a response to an OCSP query is not received in a timely manner.

Revert to CRL on

When checked, if EncrypTight does not receive a reply from the OCSP

OCSP Responder

responder or it cannot be reached, EncrypTight reads the certificate to

Failure

 

determine the location of a CRL and uses that instead of OCSP to validate

 

 

the certificate. In this case, if the CRL cannot be accessed, authentication

 

 

fails.

Check OCSP

When checked, this option specifies that ETEMS should check every

Responder Certificate

certificate in the responder’s chain of trust.

OCSP URL

 

Specifies a URL to use for the OCSP responder. This option overrides the

 

 

URL that may be included in the certificate.
