Security Zone: The Juniper Firewall adds the concept of a new security zone (Security Zone), a logical structure that is a collection of multiple physical interfaces in the same property area. When communicating between different security zones, you must pass a predefined policy check to pass, and when you communicate in the same security zone, the default state allows for no policy checks and, if configured, enforces policy checks to improve security

JunosE is an operating system used in the e-series routers of Juniper.
After the Stateless firewall filter is configured for Juniper Junos, all source or target ports c
, many IDS cannot identify each new attack because they only use one or two detection methods to detect the attack.
To successfully protect networks from increasing and complex attack threats, enterprises need to be able to accurately detect attacks and prevent them from damaging the network. Because different types of attacks use different attack methods, and each attack requires different mechanisms to identify its unique characteristics, therefore, enterprises need a device that can detect th

The L2TP tunnel (L2TP tunnel) refers to the logical link between the second-tier Tunneling Protocol (L2TP) endpoints: LAC (L2TP access aggregator) and LNS (L2TP network server). When LNS is a server, LAC is the initiator of the tunnel and waits for the new tunnel. Once a tunnel is established, the new communication between this point will be two-way. In order to be useful to the network, high-level protocols such as Point-to-Point Protocol (PPP) are then passed through the L2TP tunnel.

How to back up configuration files for Cisco, ruijie, And Juniper Devices
For a company of a certain scale, network device configuration file backup is also a task that cannot be ignored, to prevent one day after your network device fails, you can recover in the shortest time, reduces losses for the company.
The following describes the backup operations for several devices:

Censys is a new search engine used to search information about networked devices. Security Experts can use it to evaluate the security of their solutions, hackers can use it as a powerful tool to detect attack targets and collect target information in the early stage. Its functionality is very similar to the popular Shodan, but its advantage over Shodan is that it is a free search engine, ini
