There is no VTY line style of setup in "JUNOS" like cisco's vty line access-control except for "JUNOSe S/w" where the CLI is IOS alike & have vty line".
In JUNOS we configure firewall filter to restrict mgmt access. Firewall filter on lo0 is similar to cisco's line vty access-list, but here our firewall filter covers more than just device VTY access control. Configure a loopback and call the input filter there.
Here are couple of examples:
