secure dmz design

When talking about DMZ, we have gone through a long road to DMZ design. If your organization needs DMZ, it is no longer a problem, the question now is how to design a secure DMZ. In the

). From the Internet perspective, I will implement the appropriate inbound) Access Control List ACL) and try to restrict NAS. For example, using built-in firewall security restrictions can prevent traffic from untrusted interfaces, such as the Internet or DMZ, from flowing to trusted interfaces, such as the Intranet ). In addition, access to the network-oriented DMZ should be limited to the appropriate ap

The user login function is the most basic function of the Web application system. It is related to the security of user data and application system data. Designing a secure user login function involves the following aspects.(1) Conventional discussion-Password1. password length and complexity ConstraintsRestrict users to enter passwords that are very easy to crack, such as qwert, asdfg, 123456, and password.

Add this article to the favorites of simple programmers Author: thorn In the past two days, our old friend PDP gave a speech on GIFAR at BlackHat 08. As usual, PDP is very cumbersome. The topic is about how to bind a GIF or JPG file with a JAR file, and then cheat the server to think it is a GIF or JPG file. The result is an example of executing a JAR file in the client's JVM. He also gave some examples of spoofing. For example, in office2007, the doc file is actually in the zip format and conta

Tags: Solution Architect security seminar UK It is impossible for architects to be knowledgeable and omnipotent, but they are still responsible for successfully delivering available solutions. Meeting security needs is often an indispensable part, and this is often not explicitly stated. Next we will discuss the overall architecture security, such as how to write secure code, security in deployment, physical isolation at the architecture layer, encryp

revised, integrated, and improved in 1976. It is the most typical multi-level security model for information confidentiality, it is usually the basis for the design of multi-level security information systems. The security policy of the BLP Model consists of mandatory access control and autonomous access control. The security feature in mandatory access control requires that only objects of the same security level and lower security level can be read

User login is the basic function of any application system, especially for the internet banking system, the security of user login is especially important. How to design a secure login authentication program for a website is the main issue discussed in this paper.Static password There are a lot of security risks, attackers have many means to obtain static password, management password also has a higher cost

Safety | design For WEB applications, it is important to secure logins. But most WEB systems are sending plaintext when they send a login password, so it's easy for intruders to hear passwords. Of course, SSL is a good way to implement secure connections, but in many cases we can't set the server to be a WEB server with SSL. Therefore, if you add a

User logon is the basic function of any application system. Especially for online banking systems, the security of user logon is particularly important. How to design secure login authentication for a websiteProgramIs the main issue discussed in this article. There are many security risks in static passwords. Attackers can obtain static passwords in many ways and manage passwords at a high cost 《Securi

And I want to share with you the li

Article Title: design a Secure Linux network. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. As a system, its security should be carefully considered when planning the network topology to formulate security policies. After that, the security policy should be strictly en

, do the following:A) to determine whether its stat is locked, if it is blocking wait;b) Change stat to locked, re-read start, determine whether start_id equals Tmp_start, if not, then jump to step 2 to start;c) decrements its reference count, which, if not 0 after descending, needs to block the wait, and if 0, frees its memory and sets its state to null;d) increment the start_id by 1;4. Special Needs:In our design, the newly-elected leader needs to w
