It is undeniable that Juniper is a company with excellent technical capabilities and is highly competitive in the high-end router market. This is also the second company that I submitted my resume. It is also the most tortuous company in my interview experience. Haha, I don't believe it. It may take seven rounds for Juniper to interview, maybe more! Because I only went to the seventh round. @_@!First of all

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
Juniper-ha SSG Series Cluster-id solutions to scarcity problems.Http://forums.juniper.net/t5/ScreenOS-Firewalls-NOT-SRX/Cluster-ID-issue-on-ssg140/m-p/15312//true(Answer from Juniper's official technician)By default, NSRP would support up to 8 cluster ID ' s and 8 VSD ' s. As noted in the previous entry, you can increase this with the Envar, but you need to use them in multiples of 8, and the combination of cluster ID ' s and VSD ' s cannot exceed . Y
In the front I sent an article "Juniper Firewall diagram L2TP VPN Configuration", we learned from that article how to configure. But we know that the L2TP VPN is only connected to our L2TP VPN server, but it doesn't encrypt our data, and we know that IPSec's data is encrypted, and if the IPSec-unaware friend can look at my previous IPSec VPN concepts (i) And the concept of IPSec VPN (ii) to understand. Okay, so our IPSec needs to be encrypted, and our

, 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

Firewalls are often deployed on the edge of our network environment to isolate the network and protect the security of the Intranet and Internet. For example, in the edge network, MIP a public IP address to a VPN device on the Intranet, for the sake of security, EDGE networks need to have selective open ports or Protocols.
