Authentication and Access Control
- Unified policy support for firewall user
authentication (SRX Series and vSRX)—Starting in Junos OS Release 21.2R1, we support
firewall user authentication in a security policy with dynamic applications (unified
policy). You can configure pass-through or web authentication in the unified policy to
restrict or permit users to access network resources.
Firewall user authentication support in the unified policy provides an additional layer of protection in a network with dynamic traffic changes.
[See Configure Firewall User Authentication with Unified Policies.]
- Display dynamic-applications and URL
category hit counts in a security policy (NFX Series and SRX Series)—Starting in Junos
OS Release 21.2R1, we've enhanced the
show security policies hit-count
command to include the dynamic applications and URL categories options. You can now display the utility rate of the policy according to the number of hits for the dynamic applications and URL categories. Support to configure boot order (SRX1500 and SRX4600)—Starting in Junos OS Release 21.2R1, you can choose to reboot your security devices from a USB device without power cycling. Use the
request system reboot usb
configuration statement to reboot your device from USB. This statement allows your security devices to detect a new USB device with a soft reboot.
