Whenever I hear other software executives complaining about their "cascade" development process, I always ask them why they don't try more agile methods. And the most common answer is that they don't know how to start. In fact, if a book is all about agile development, it won't make agile easier. Explain to the project management team that you want to give up everything you know, and then try something completely different that really requires a whole description, which will take some effort to

Cause abnormal information leakage, even the system crashes; a malicious user may illegally steal a legitimate user's communication message in a transmission network, thereby obtaining sensitive information that should not have

"Computer newspaper" mentioned a can easily through the Kabbah, rising, Norton's active defensive function of the Trojan: Byshell. So search on the Internet, search to the Byshell promotion version of the description is: can cross the Norton rising through the default settings active defense. I put a promotion version back to try the micro-point can prevent, the generation of server after the operation, micro-point did not disappoint, immediately repo

Active and passive security defenseIn the process of building a secure network environment, security products, as the first security line of defense, are receiving more and more attention from users.A security product is a combination of components set between different networks or network security domains. It is the only portal for information between different networks or network security domains. It can control inbound and outbound Network Informat

1. Defensive base 1.1. How big is the attack flow?When it comes to DDoS defense, the first thing to do is to know how much of an attack has been hit. The problem seems simple, but in fact there are a lot of unknown details in it. In the case of SYN Flood, in order to increase the efficiency of sending SYN wait queues on the server, the IP header and TCP header are not populated with optional fields when the attack program fills the header, so the IP

restricted file. By examining the two connections, the server is protected from this situation: the control connection is connected with a trusted host connection and the data connection is not. Similarly, customers should examine the IP address of the remote host after receiving an open port connection in the listening mode to ensure that the connection is established by the desired server. 2. Password protectionto reduce the risk of brute-force password guessing attacks over FTP servers, it i

There have been articles on the web about Cross-site scripting attacks and defenses, but with the advances in attack technology, previous views and theories about Cross-site scripting attacks have not met the need for attack and defense today, and because of this confusion over cross-site scripting, Cause now many programs, including the current dynamic network has a cross station script filtering is not strict problem, I hope this article can write p

software to simulate a lot of this, the consequences can be imagined. A server consumes a lot of system resources and network bandwidth to handle these vast amounts of half-open information, so that the server will no longer be free to handle normal user requests (because the customer's normal request ratio is very small). This server will not work, this attack is called: Syn-flood attack. So far, the defense of DDoS attacks is more difficult. First

vulnerabilities, ASP language itself including IIS also exist security vulnerabilities, so the vast majority of ASP sites can be breached, but the network management Smart site left a loophole is very few, need to patiently look for. "Know each other, win," to prevent the ASP Trojan must first understand his principle and operating mechanism. · using ASP Trojan to achieve FTP reconciliation and compression · the principle and basic precaution method of ASP Trojan horse · an ASP Trojan program s

. There are many forms of buffer overflow vulnerabilities and attacks, and we will describe and categorize them in the second part. The corresponding defense means are different with the attack method, we will put in the third part of the description, its content includes for each type of attack effective defense means. We also want to introduce stack protection methods, which are effective in resolving buf

This paper builds a small network defense system with snort and iptables in Linux environment, provides a remote management tool from PHP page, and gives the implementation and explanation of key program. Introduction Snort is currently a very popular light intrusion detection system. However, at present, the processing of snort detection results mostly stay in the log or simply notify the network administrator, the administrator of the audit to det

, such as limit, it is often used in business logic such as paging and searching. You cannot use pre-processing queries, you need to encode the input data or filter it strictly. For example, the number can only be 0-9, using the white list principle to filter.PS: parameterization can only parameterize the data section and cannot be parameterized with keywords and identifiers. This is the limitation of preprocessing, and from the point of view of attackers, you should look for points where prepro

Industry users in Internet cafes, school data centers, and local area networks can use the following methods to prevent the virus: Chinese name: robot dog Virus Virus named: Trojan-Downloader.Win32.EDog.h Virus features: uses the penetration recovery card to paralyze Internet cafes, school data centers, and the com

Experts can easily teach you how to deploy defense measures against DDos attacks There are no 100% effective defense measures for DDoS attacks. However, the attacker must make more resources and efforts than the defender to have such "power". Therefore, as long as we have a better understanding of DDoS attacks and actively deploy defense measures, it can also mit

vulnerable memory. The second reason is a developer error. The third reason is that the compiler generally does not provide defense functions. It is easy to remedy the first problem, but since then C and C ++ have become different languages. Developers can partially solve errors through training, but I have not really seen the rise of educational institutions in this regard. There are indeed some security training institutions in the industry, but we

CSRF is a common vulnerability of web applications, and its attack characteristics are large but very covert, especially in the context of a large number of Web 2.0 technology applications, where an attacker can launch a csrf attack without the user's awareness. This paper will make a systematic exposition of its basic characteristics, attack principle, attack classification, detection method and precautionary means, and enumerate the attack examples.Wen/H3C
