1. Denial of service attackA service denial attack attempts to prevent you from providing services by crashing or crimping your service computer, which is the most easily implemented attack behavior, mainly including:Ping of Death (ping of Death)Overview: Due to the limitation of the maximum size of the router in the early stages, many operating system implementations on the TCP/IP stack are 64KB on the ICM

Analysis of common Vulnerability attacks in PHP programs Overview:PHP program is not impregnable, with the extensive use of PHP, some hackers are also in the absence of the trouble to find PHP, through the PHP program vulnerability to attack is one of them. In the section, we will move from the global variables, remote files, file uploads, library files, session files, data types, and error-prone functions analyze the security of PHP. 　　 How do I

In the development of the Web site, we may give a person a security problem, let me introduce some common SQL injection attack method Summary, novice friends can try to reference. 1. Escape characters are not properly filtered This form of injection or attack occurs when the user's input does not have an escape character filter, and it is passed to an SQL statement. This causes the end user of the applicati

How to attack common vulnerabilities in PHP programs (on) Translation: Analysist (analyst) Source: http://www.china4lert.org How to attack common vulnerabilities in PHP programs (on) Original: Shaun Clowes Translation: Analysist This article is translated because the current article on CGI security is taking Perl as an example, and there are few articles devoted to asp,php or JSP security.

XML security-XML attack methods you don't know The XML eXtensible Markup Language is designed to transmit and store data in various forms. Some features designed in XML, such as XML schemas (following XML Schemas specifications) and documents type definitions (DTDs), are both sources of security issues. Even though it was publicly discussed for the last decade, a large number of software still died in XML attacks. 0x00 XML Introduction XML eXtensible

Session attack (session hijacking + fixation) and defense, Session session1. Introduction Session is undoubtedly the most important and complex for Web applications. For web applications, the first principle of enhanced security is-do not trust the data from the client. data verification and filtering must be performed before it can be used in the program and then saved to the data layer. However, to maintain the status of different requests from the

1, Syn/ack flood attack: This attack method is the classic most effective DDoS method, can kill various systems of network services, mainly by sending a large number of SYN or ACK packets to the compromised host, causing the host's cache resource to be consumedDo or are busy sending response packets resulting in denial of service, because the source is forged so it is difficult to trace, the disadvantage is

Zhanggo blog A long time ago to share a CC attack defense script, write is not good, but was 51CTO accidentally reproduced. Since then, the blog has often been taken to practicing the road of not return. Of course, there are still a lot of friends in the production environment to use, and will leave a message to ask related questions. Based on the needs of these questions, I spent some time writing a more satisfying lightweight CC

1. Tear Drop attack: The modified IP packet is sent to the destination host, the length of the IP header is negative, the packet length is treated as unsigned integer, and the system attempts to replicate the extremely long packet, which may crash or restart Detailed For some large IP packets, it is often necessary to split the transmission, this is to meet the link layer of the MTU (maximum transmission unit) requirements. For example, a 6 000-byt

In general, DOS network packets are also transmitted over the Internet using the TCP/IP protocol. These packets themselves are generally harmless, but if the packet is too excessive, it will cause network equipment or server overload, the rapid consumption of system resources, resulting in denial of service, this is the basic principle of Dos attack. Dos attacks are difficult to protect, the key is that illegal traffic and legitimate traffic is mixed

1. Escape characters are not filtered correctly This form of injection or attack occurs when the user's input does not escape character filtering, which is passed to an SQL statement. This causes the end user of the application to perform operations on the statements on the database. For example, the following line of code demonstrates this vulnerability: The code is as follows Copy Code "SELECT * from users WHERE name =

CC Attack principle CC is primarily used to attack pages. We all have such experience, that is, when visiting the forum, if this forum is relatively large, more people visit, open the page will be slower, right?! Generally speaking, the more people visit, the more The forum page, the larger the database, the frequency of access is also higher, the system resources occupied is quite considerable, now know wh

program | attack [Global variables] Variables in PHP do not need to be declared in advance, they are created automatically the first time they are used, and their types do not need to be specified, and they are determined automatically according to the context environment. From a programmer's point of view, this is an extremely convenient way of handling. Obviously, this is also a very useful feature of the rapid development of languages. Once a varia

many ways to look for Hash collisions, such as birthday attacks for general attacks and the modulo difference method. These methods are used to attack the intermediate encounter attacks of Hash schemes with a group chain structure, modify group attacks based on Modulo-arithmetic Hash functions. Here I will briefly introduce the following four methods for finding a collision: Equals substrings Birthday attack
