best intrusion detection software

Currently, application-level intrusion into applications and their background databases has become increasingly rampant, such as SQL injection, cross-site scripting attacks, and unauthorized user access. All these intrusions may bypass the front-end security system and initiate attacks against data sources. To deal with such threats, the new level of security stands out, which is application security. This security technology applies the traditional n

Summary of the Elevation of Privilege of intrusion penetration Detection TechnologyHello everyone, I have never written any articles to share with you at the beginning. I hope you will be guilty of guilt.Today we have time to write a process and share it with you, because I think it is worth sharing.Well, let's get down to the truth, and the intrusion process wil

hate to call all the technical skills of the company to show them what a trojan is and what a pony is, and then demonstrate how to upload a Trojan, grandma's, and the popularity of hacker tutorials. Question 2. The website encountered another problem. The last problem was solved for only two months, and the website was hacked and infected. If the boss had to say this time that I had a problem, he would leave immediately, that's why people who do not know more about technology can't talk to each

However, when there are so many pages, it is difficult for you to detect vulnerabilities on that page one by one. if you write the following detection code, I did not expect this to be done simply, and you can use this method to optimize your SQL. Step 1 create an SQL log table The code is as follows: Create table [dbo]. [my_sqllog] ( [Id] [bigint] IDENTITY (1, 1) not null, [Hit] [bigint] NULL, [Sqltext] [varchar] (max) COLLATE

is hard to achieve. People who do not know this field often think that IDS is like a omnipotent key to solve all security problems. For example, some organizations have spent a lot of money to purchase commercial IDS. Due to improper configuration, these companies have even false positives, which immediately fills the database with a large amount of packet loss and then crashes. This kind of attitude makes people think that everything is fine as long as IDS are randomly placed on the Internet,

Most Trojans may exploit system vulnerabilities, which is already familiar to everyone. As a result, security detection and removal products and management personnel focus on this aspect. However, new trends show that Trojan Horse propagation has begun to exploit a large number of common application software vulnerabilities, such as instant messaging software, wh
