Updating System Security
System security updates are NSM4000 appliance operating system-level patches that
protect the system against any future reported security vulnerabilities. The NSM4000
appliance checks for new updates daily by connecting to Juniper Networks.
To manage system security updates:
1.
On the NSM4000 appliance Settings menu, enter 8 at the prompt.
2.
Enter one of the following values to select the option:
• 1 to check for and install security updates now.
•
2 to enable or disable automatic security updates.
•
3 to check for and install the latest available NSM4000 appliance version.
• 4 to set the proxy for security update check.
3.
Follow the prompts to manage security updates and then return to the NSM appliance
Settings menu.
Configuring Extended HA
The extended high availability configuration is the most extensive and complex
configuration but has the greatest protection against component failure. A failure of the
primary Device server would cause failover to the standby Device server. This new Device
server would attempt connection with the primary GUI server. Failure of a GUI server
would also cause failover to the standby GUI server. The current Device server would
attempt to connect to the standby GUI server after a timeout period. In this configuration
the failure of a single component has minimal impact on the system as a whole. In
addition, the distributed system gives each service more system resource.
To configure extended HA:
1.
On the NSM4000 appliance Settings menu, enter 10 at the prompt.
2.
The serial console displays the following warning:
WARNING: Configuring for Extended HA will clean the existing build completely Do you
want to continue(y/n):
3.
Enter y to continue with the extended HA configuration.
For additional details about configuring extended HA, see the Network and Security
Manager Installation Guide .
Saving Setup Options
Before you configure the regional server, the NSM4000 appliance opens the Apply Change
submenu. If you quit out of a menu after making changes, he NSM4000 appliance also
opens this screen and prompts you to save your changes. Updates are enabled by default.
