In our Webcast entitled "the secret to effectively use IDS and IPS" based on the user's on-demand video, the guest speaker Jeff Posluns provides the skills to use IDS/IPS to actively manage security vulnerabilities and thoroughly examine the security status of an enterprise. The following are some questions that Jeff answered during the live broadcast. Q: Should I receive IDS alerts only from one informatio

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

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

Security Managers face many challenges in protecting enterprise network servers from attacks. Although the Intrusion Detection System (IDS) was once widely used, the attack methods on the Internet are constantly being improved. At the same time, the signature technology IDS cannot detect new and deformation attacks, therefore, traditional IDS gradually show their limitations in terms of initiative. So what are the choices for enterprises? Intrusion Protection System (

PHP Gets the Remote Web page content function when the same domain name corresponds to multiple IPs The FGC is simply read and encapsulates everything. Fopen also carries out some encapsulation, but requires you to iterate through all the data. Fsockopen This is the socket operation of the straight plate. If you just read an HTML page, FGC is better. If the company is online through a firewall, the general file_get_content function will not be. Of cou

SSH connection after login:Entercd/etc/sysconfig/network-scriptsgenerally the first is the system default IP edit file. Some systems will have multiple connections, X36 on the new VPS, there will be 4 connections, that is, there are 5 files beginning with ifcfg, Ifcfg-lo is the loopback port. Preferably vi into the file editor, to see which file has the initial default IP, in the file modification!

Because the author recently encountered such a situation, the number of servers to do networking planning, the client side gives a limited amount of IP,Not enough for each host to be assigned to IP, but I think again, not necessarily every service must use the DCN network address,So I think I can configure the network card that must use the DCN network address two IP, a DCN network address, a private IP address we define ourselvesThe author takes the operating system under VMware Virtual machine

Recently do the system performance optimization encountered a problem, after the solution to share to everyone.When we establish a connection through the socket, if our computer cannot connect with the specified site, then this will cause the system to be stuck on the socket connect method,We all know that the socket to establish a connection requires three handshake, the computer sends a message header to the server, the server returns, this time the socket basic connection is successful, but i

Test topology: Note: The TCP Reset command cannot be issued from the original sensor port of the IPs because of the constraints of the simulated environment, so the test emits a TCP reset with the IPs other interfaces. 2.

=ethernetOnboot=yes Two, a single network adapter to bind multiple IPsSometimes we need to configure multiple IPs on a NIC, for example, in the example above, we also need to configure IP 192.168.168.2 and 192.168.168.3 for eth0. Then you need to create a new two configuration file under/etc/sysconfig/network-scripts:ifcfg-eth0:0 content is as follows: device=eth0:0Bootproto=staticipaddr=192.168.168.2netmask=255.255.255.0Onboot=yes
