Use the lssecurity command to display the current system Secure Sockets Layer (SSL) or Transport Layer Security (TLS) security settings.

Syntax

Parameters

-nohdr
(Optional) By default, headings are displayed for each column of data in a concise style view, and for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.
Note: If no data exists to be displayed, headings are not displayed.
-delim delimiter
(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a 1-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.

Description

This command displays the current system security settings system-wide, including the SSL or TLS and SSH security levels.

This table provides the possible values that are displayed for the lssecurity command.

Table 1. lssecurity attribute values
Attribute Value
sslprotocol Specifies the current security level setting, a numeric value of 1, 2, 3, or 4.
Use these sslprotocol security level settings.
  • 1 - Allows TLS 1.0, TLS 1.1, and TLS 1.2, but disallows SSL 3.0.
  • 2 - Allows TLS 1.2, but disallows TLS 1.0 and TLS 1.1.
  • 3 - Also disallows TLS 1.2 cipher suites that are not exclusive to 1.2.
  • 4 - Additionally disallows RSA key exchange ciphers and static key exchange ciphers.
Note: You cannot use the management GUI if the sslprotocol value is set to 1 and you are using SSL 3.0 or TLS 1.0.
sshprotocol Specifies the current security level for SSH, a numeric value of 1 or 2.
Use these sshprotocol security level settings.
