established.The main drawback: slow data, but custom-made chip, can compensate for this shortcoming to some extentKey Benefits: Improved security3. Agent-based firewallsAgents are located in the application layer, exhaustive search protocol, no ACK attack problems encountered by traditional packet filters, because ACK is not part of a meaningful application request (--not understood).An agent-based

Alert window. Of course, there are many other cases, so it is not enough to test this case. As you know, JavaScript may be injected into various fields in the request: parameters, HTTP headers, and paths. Although, in some cases, especially the HTTP Referer header), it is difficult to use a browser to perform attacks. Summary XSS attacks are one of the most common application layer attacks that hackers use to intrude into

hacker maliciously hacked into its computer system and stole 40 million credit card information. This information includes the cardholder's name, account number, etc. This is the most serious credit card data leak in the history of the United States. The attack not only on consumers, the company caused a huge loss, and even the U.S. credit card industry has a serious impact!1.1 The misunderstanding of WEB securityBut what is

However, IDS/IPS technology lays a good technical foundation for future network security, many of the new Web application firewalls and next-generation firewalls are derived from IDS/IPS. In addition, IDS/IPS still have br

"Go" article to understand Web server, application server, Web container and reverse proxyWe know that people of different colors have a big difference in appearance, and twins are difficult to identify. The interesting thing is that the Web server/web container/

and other related emerging Web defense technologies can successfully block Web application layer attacks and scan Web application vulnerabilities. Web application security scanners can

the associated clients, while the reverse proxy is used as a proxy on the server side (such as the Web server) instead of the client. The client can access many different resources through the forward proxy, and the reverse proxy is where many clients access resources on different back-end servers without needing to know the existence of these back-end servers, and to assume that all resources come from this reverse proxy server.2. The main role of t

currently relatively small and expensive, if you place the web server in the firewall, it will definitely affect the Internet access performance. A library adopts IDS (Intrusion Detection) + Web servers (server firewalls, relatively low-end, without affecting traffic) + application servers + database servers (firewall

architecture (CORBA) and Remote method Invocation (RMI): The main benefit of CORBA is that the client and server can be written in different program development reviews. This possibility is due to the fact that the object is defined by interface definition Language (IDL) and that communication between objects, customers, and servers is implemented by object Request Brokers (orbs). Remote method Invocation (RMI) allows you to create Java-java distributed applications. In this technique, a remo

In the current network environment, applications have become the main carrier of the network, and more threats to network security come from the application layer, which puts forward higher requirements for network access control. How to precisely identify users and applications, block applications with security risks, ensure normal use of valid applications, and prevent port theft has become the focus of users on network security. The

Web application scanning systems should be able to provide different people with information about different applications at the same time. For enterprises, it is important to find a Web application scan solution that is easy to use and allows multiple users to scan and report at the same time without conflict with ea

applications are vulnerable to attacks through servers, applications, and internally developed code. These attacks bypass the Perimeter Firewall security measures because ports 80 or 443 (SSL, secure socket protocol layer) must be open for normal operation of applications.
