radware waf

In order to solve the bottleneck of single machine processing and enhance the usability of software, we need to deploy software on multiple servers to enable multiple level two subdomains to be deployed on separate servers based on business functions, or through load balancing techniques such as DNS polling, radware, F5, lvs, Etc.) lets multiple channels share a group of Servers. When we branch the site program to more than one server, because the ses

capacities, then the "weighted least connections" approach is more appropriate: Consider the number of connections while also weighing the administrator's customized weights based on server conditions.Source IP hashes (source IP hash)This is done by generating a hash of the requested source IP and using the hash value to find the correct real server. This means that the same server is always the same for the same host.RandomThe random algorithm of the system, according to the list size value of

Its unit price is relatively inexpensive, and has a high level of scalability and intelligent services. It also has network monitoring and detection functions, global load balancing and mitigation of certain DDoS attacks.In addition, Radware equipment has some features is relatively easy to update and upgrade, can sense the application servic

) High Performance computing cluster The High performance computing cluster uses different computing nodes to allocate computing tasks to clusters to improve the computational ability, so it is mainly applied in the field of scientific computation. The more popular HPC uses a Linux operating system and some other free software to perform parallel operations. This set of cluster configurations is often referred to as the Beowulf cluster. Such clusters typically run specific programs to perform hp

Load balancing is an eternal topic for a large web site. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 Big-ip, Citrix netscaler, Radware, etc., although it can solve the problem, but its high price is often prohibitive, So load-balancing software is still the choice for most companies.

January SQL Killer caused more than 20,000 database servers in China to be affected, and the international export of a backbone network was nearly paralyzed; the March red Code worm's F variant spread to the Internet as much as 10多万次; the August shockwave and Sobig virus have so far been in the network, The affected host is already close to more than 2 million units. So many viruses make network administrators tired, but the loss is unavoidable. During the peak of the virus outbreak, some ente

For a large web site, load Balancing is an eternal topic. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 big-IP, Citrix NetScaler, Radware and so on, although can solve the problem, but its high price is often prohibitive, So load balancing software is still the perfect choice for most companies.

firewall market with more concepts than examples, what kind of products can meet customer needs? What is the firewall market in the eyes of manufacturers? A dedicated firewall like the Web application Firewall (WAF) is very promising. Web application firewalls can ensure that web-based malware does not set foot in your business. It can also prevent hackers from exploiting vulnerabilities into the 7th layer of OSI, which in turn prevents further intr

Some events are infinite loops, such as Flowmonitor, RIPng, Realtimesimulator, and so on, and these events need to stop using stop. 9.

Case variantsThis technique is useful when keyword blocking filters are not smart, and we can change the case of characters in the keyword string to avoid filtering because the SQL keyword is handled in a case-insensitive manner.For example: (The following code is a simple keyword blocking filter)function WAF ($id 1) { if (strstr ($id 1,' Union ')) { echo ' error:lllegal input '; return; } return $id 1; T

The Tomcat (JSP) parses the first parameter, which displays the contents of the id=1.Take slices as a description of the parameter resolution for most servers.Here we want a question: index.jsp?id=1id=2 request, for the server configuration in the first diagram, the client request first Tomcat,tomcat parse
