BACKGROUNDToday read an article based on the constraints of SQL attack, feel very good, but the practice and found a lot of problems, although the use of a certain demand, but the author's ideas are worth learning. The main idea in the original text is to use the special processing method of the database to achieve the goal of exceeding the level of authority. The

XSS attacks, the full name of cross site scripting attacks (Scripting), are abbreviated as XSS, primarily to differentiate from cascading style sheets (cascading stylesheets,css) to avoid confusion. XSS is a computer security vulnerability that often appears in web applications, allowing malicious Web users to embed code into pages that are available to other users. The code includes HTML code and client script. For cross-site scripting attacks, the hacker consensus is that cross-site scripting

Among them,SQL injection is a common attack method, the common practice of developers is to constantly filter, escape parameters, but our php Dafa inherently weak type of mechanism, always let hackers have the advantage, bypassing defense and defense is always in the infighting.

up and closes off quickly performs very well even with very large databases works with SQLite Indexing (i.e. retrieving a single record using an indexed search can incur as little as 5% overhead above a standard SQL ITE database)It does not encrypt the table or column, which means that his database key is only one, which is the key.Sqlcipher is used on iOS:1) Add sqlite3.h and SQLITE3.M to the project;2) Connect to the database using the following code:The key is the one we need! The key is the

the background of SQL is "select field1,field2 from table where id=", at this time the foreground input "5 or 1=1", even single quotation marks can be omitted, more direct injection.2. As you can see, SQL injection is rigged in the conditional statement in where, and the foreground is passed to the matching object in the where, which is the basic principle of SQL injection attack. Although we can do more select,delete,drop,update and inserts in the i

With the continuous expansion of Linux enterprise applications. A large number of network servers are using the Linux operating system. The security of Linux servers can be more and more concerned. This is listed here according to the depth of the attack on the Linux server and proposes different solutions. With the expansion of Linux enterprise applications, there are a large number of network servers using the Linux operating system. Linux server se

Author: Hunger Garfield (QQ120474) Iojhgfti@hotmail.com Absrtact: For the increasingly rampant denial of service (DoS) attacks on the Internet, this paper analyzes the performance defects of the traditional random data packet tagging algorithm, proposes a new return tracking algorithm based on hash message authentication code, and hppm that the algorithm improves the efficiency and accuracy of the return tracking DoS attack by analyzing its performan

Research on XPath injection attack and its defense technology Lupeijun (School of Computer Science and Technology, Nantong University, Nantong 226019, Jiangsu) Summary XML technology is widely used, and the security of XML data is more and more important. This article briefly introduces the principle of XPath injection attacking XML data. On the basis of the common defense methods proposed by predecessors, a general test model of XPath injection

After the emergence of WLAN technology, "security" has always been a shadow around the word "wireless". Attacks and cracking against security authentication and encryption protocols involved in wireless network technology have emerged. Currently, there may be hundreds or even thousands of articles on how to attack and crack WEP on the Internet, but how many people can truly break WEP's encryption algorithm? Next I will introduce some knowledge about W

SYN attack schematic diagram: TCP has to shake hands three times before passing data, and the SYN attack is to send a SYN packet to the server and spoof the source IP address.When the server receives the SYN packet, it joins the backlog queue and sends the SYN-ACK packet to the source IP and waits for the ACK packet to complete the three handshake connection.Because the source IP address is forged without
