security config modify


Modify Security Configuration Options

Availability: This command is available to cluster administrators at the advanced privilege level.


The security config modify command modifies the existing cluster-wide security configuration. If you enable FIPS-compliant mode, the cluster will automatically select only compliant TLS protocols (currently TLSv1.2 and TLSv1.1). Non-compliant protocols are not enabled when FIPS-compliant mode is disabled. Use the -supported-protocols parameter to include or exclude TLS protocols independently from the FIPS mode. All protocols at or above the lowest version specified will be enabled, even those not explicitly specified. By default, FIPS mode is disabled, and Data ONTAP supports the TLSv1.2 and TLSv1.1 protocols. For backward compatibility, Data ONTAP supports adding SSLv3 and TLSv1 to the supported-protocols list when FIPS mode is disabled. Use the -supported-cipher-suites parameter to control which TLS cipher suites are permitted by the system. By default the supported-cipher-suites setting is TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_CAMELLIA_128_CBC_SHA, TLS_RSA_WITH_CAMELLIA_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_GCM_SHA256, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA256, TLS_DHE_DSS_WITH_AES_256_GCM_SHA384, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA256, TLS_DHE_DSS_WITH_CAMELLIA_128_CBC_SHA, TLS_DHE_DSS_WITH_CAMELLIA_256_CBC_SHA, TLS_DHE_DSS_WITH_SEED_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA256, TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA, TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA, TLS_DHE_RSA_WITH_SEED_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_PSK_WITH_AES_128_CBC_SHA, TLS_PSK_WITH_AES_128_GCM_SHA256, TLS_PSK_WITH_AES_256_CBC_SHA, TLS_PSK_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_SEED_CBC_SHA, TLS_SRP_SHA_WITH_AES_128_CBC_SHA, TLS_SRP_SHA_WITH_AES_256_CBC_SHA, TLS_SRP_SHA_DSS_WITH_AES_128_CBC_SHA, TLS_SRP_SHA_DSS_WITH_AES_256_CBC_SHA, TLS_SRP_SHA_RSA_WITH_AES_128_CBC_SHA, TLS_SRP_SHA_RSA_WITH_AES_256_CBC_SHA . Select a cipher suite which is available with the corresponding selected protocol. An invalid configuration may cause some functionality to fail to operate properly. Valid values for supported-cipher-suites are listed at "" published by IANA. After modifying the security configuration, reboot all the nodes manually.


-interface <SSL> - (DEPRECATED)-FIPS-Compliant Interface
Note This parameter has been deprecated in ONTAP 9.8 and may be removed in a future release of Data ONTAP.
Selects the FIPS-compliant interface. The only valid value is ``_SSL_`` .
[-is-fips-enabled {true|false}] - FIPS Mode

Enables or disables FIPS-compliant mode for the entire cluster. Default is false .

[-supported-protocols {TLSv1.2|TLSv1.1|TLSv1|SSLv3}] - Supported Protocols

Selects the supported protocols for the selected interface. Default is TLSv1.2,TLSv1.1

[-supported-ciphers <Cipher String>] - (DEPRECATED)-Supported Ciphers
Note This parameter has been deprecated in ONTAP 9.8 and may be removed in a future release of Data ONTAP. Use the supported-ciphers-suites parameter instead.
Selects the supported cipher suites for the selected interface. Default is ``_ALL:!LOW:!aNULL:!EXP:!eNULL_`` .
[-supported-cipher-suites <Cipher String>,…​] - Supported Cipher Suites

Selects the supported cipher suites for the selected interface.


The following command enables FIPS mode in the cluster. (Default setting for FIPS mode is false )

cluster1::> security config modify * -is-fips-enabled true

The following command limits the supported protocols to just TLSv1.2 in the cluster. (Default setting for supported protocols is TLSv1.2,TLSv1.1 )

cluster1::*> security config modify * -supported-protocols TLSv1.2

The following command limits the supported cipher suites in the cluster to the listed ciphers.

cluster1::*> security config modify * -supported-cipher-suites TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
