Juniper Firewall as a network of checkpoints, in addition to control the intranet user access outside the network can also control the access to the network, if the user intranet servers need to publish services to the external network needs to use the Juniper Firewall network mapping function, Here are two of the most commonly used methods of MIP and VIP. The configuration of

The IPS VLAN Group is a IPS6.0 feature, where VLAN group blending mode requires a VLAN tag when configuring mirroring, which is not the default in GNS, and VLAN group online mode is an overlay of online mode and VLAN group. Configure the online interface pair first, then configure VLAN Group on the online interface pair to tell the IPs which VLANs are running on it, and support to send different VLAN data t

In the first two articles, we introduced to readers of the IT168 Security Channel How to Use the IPS intrusion defense system to immediately discover and analyze the host vulnerabilities of connected devices, today, we will continue to explain the behavior processing method, a major feature of the intrusion defense system IPS. Through the behavior processing method, we can more flexibly choose the measures

IPS: Intrusion Prevention SystemIDS Intrusion Detection SystemIntrusion detection System (IDS) is a security product that focuses on risk management by detecting and alerting the abnormal and potentially intrusive data, informing the user of the real-time situation in the network, and providing the corresponding solution and processing methods.Intrusion Prevention System (IPS) is a security product that foc

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.

A device that analyzes traffic has been deployed in the previous period and needs to mirror the port's traffic to a single copy of the server's NIC.Because the Juniper Operation command is unfamiliar, the online command is also relatively few. So write a blog record.EXthe port mirroring of the switch allows the port to be in traffic, or the outbound traffic is mirrored separately, andethernet-switchingof theFirewall Filter, you can specify that eligib

Today to a customer in the Juniper SSG140 firewall debugging L2TP VPN, when established, the client asked me to establish 350 L2TP VPN users above the firewall, immediately dumbfounded, if manually set up 350 L2TP VPN users that will not be exhausted! A small program was written specifically to generate the L2TP VPN user command (pictured below) for the user's needs. With this applet, you need to fill in the relevant parameters, such as how many us

Cost-effective overseas VPS brand Vultr VPS announces a new feature called "Reserved IPs", as the name implies to help you keep the server IP address for later use.This requirement is because users often create new, delete a VPS server, the default is assigned to the random server IP address. If you are in the company of a certain size of server cluster, you prefer to keep the original IP address unchanged, saving time to modify the configuration.Usin

using the Uniq command, you can filter out duplicate lines in a text file, statistics, and so on, and it also accepts input from the pipeline. With awk, you can even manipulate columns in rows, such as counting the number of independent IPs in Nginx log messages, listing the most visited IPs, and so on. It is important to note that Uniq only handles connected rows, so the sort operation is generally done fi

When using Python Crawlers, we sometimes use IP proxies. Inadvertently found a free proxy IP site:http://www.xicidaili.com/nn/. However, the discovery of a lot of IP is not used. Therefore , a script is written in Python, which can detect the proxy IP that can be used . The script is as follows:#encoding =utf8import urllib2from bs4 import beautifulsoupimport urllibimport socketuser_agent = ' mozilla/5.0 (Windows NT 6.3; WOW64; rv:43.0) gecko/20100101 firefox/43.0 ' header = {}header[' user-agen
