Login Security - Dell SMA 200 Administration Manual

Login Security

The Login Security section provides a way to configure administrator/user lockout for a set period of time (in
minutes) after a set number of maximum login attempts per minute.
HTTP DOS Settings
The HTTP DOS Settings section is used to configure the maximum concurrent TCP connections (20-100, default
20) a client can open with the Secure Mobile Access web server.
Global SSL/TSL Settings
The Global SSL/TLS settings section allows the administrator to configure Secure Sockets Layer (SSL) and
Transport Layer Security (TSL) settings globally from the System > Administration page.
Configure the following settings:
• Enforce Forward Secrecy — Enable this option to allow current information to be kept in secrecy, even
if the private key is compromised in the future. Note that browsers that do not support Forward Secrecy
might not be able to connect to the SMA/SRA appliance. The performance of this feature can decline
depending on the ciphers that the client browser supports.
• Verify Backend SSL Server Certificate for Proxy connections — When this option is enabled, the
connection is dropped if the backend SSL/TLS server certificate is not trusted. The verification depth is
10. Alert level log messages are also generated when this option is enabled.
Capacity Matrix
The Secure Mobile Access Capacity Matrix Report is a downloadable .PDF file that allows you to view the total
number of various connections, interfaces, portals, domains, groups, users, and so on, available for your
specific SMA/SRA appliance model. Click Download to have the report downloaded to your local system.
