source of the visitorUse the unicast Reverse Path forwarding to check if the IP address of the visitor is true and, if it is false, it will be masked by a reverse router query method. Many hacking attacks often confuse users with fake IP addresses, and it's hard to find out where it comes from. Therefore, the use of unicast Reverse Path forwarding can reduce the emergence of fake IP addresses and help improve network security.(7) Filter all RFC1918 I

Andrew Collins, cybertrust's security manager, also said that if you can ensure that network resources, including web cam

Oracle is a database that appeared earlier, but its market share is very large, often on some large databases. In addition to supporting a variety of SQL statements, it also provides a variety of packages, stored procedures, and even supports features such as java and library Creation, such powerful functions provide great convenience for Hacking. Oracle has many default accounts and many stored procedures. These stored procedures are created by the s

1, the spirit of the hacker attitude is very important, but the technology is more important. Although the attitude of hackers is irreplaceable, with the invention of new technology and the substitution of old technology, these tools have changed slowly over time. For example: Always learn to write programs with machine code until recently we started using HTML. However, at the end of 1996, of course, this is the basis of hacking skills. In 1997, of c

With the development of society, the technology is developing rapidly and the virus is constantly updated. There are always worms that can easily find some hacking tools to attack others. Many people are inexplicably attacked by information bombs or other attacks when using QQ. Most of the reasons are that you first use a tool to find out your IP address and then use the attack software. With the development of society, the technology is developing r

multiple queries is not only slow, boring, but not easy to manage.Remember, these tests are just mining tests conducted by Google. They do not represent all hackers and Internet security. These are not the best tools to test all system vulnerabilities. As an alternative, you must use "multi-layer" testing: Google and other free, open-source, and-in my opinion, most comprehensive and reliable-commercial tools for testing, these commercial tools I recommend with SPI Dynamics WebInspect (for Web a

Make A Contract with IE and Become a XSS Girl! This is the topic of Yosuke HASEGAWA, a representative of the Japanese hacker stream, on hit2011.

In PHP often see the following code if (!defined (' in_ecs ')) {die (' Hacking attempt '); The reasons and principles of the implementation are as follows: There are some in Ecshop. PHP pages are not required to be accessed directly by the user via a URL, such as/includes/init.php, which does not require direct access and accesses your URL through the URLs/includes/ Init.php is meaningless, so we add define (' In_ecs ', true) to the PHP that can be di
