How hackers bypass IDS for Buffer Overflow
As a heavyweight product of enterprise security protection, IDS naturally becomes a target for hackers to crack. It turns out that bypassing IDS protection is completely feasible. The next article will explain how hackers can bypass IDS through buffer overflow during attacks.

In fact, when talking about IDS, I think the administrators and friends must be familiar with it. but I still want to briefly talk about the definition of

Intrusion detection systems (intrusion detection system, IDS) are the hot security products in the past two years, which play a role in the network security system can detect intrusion behavior and alarm. The intrusion behavior described here covers a wide range of activities, including not only hacker attacks, but also various network anomalies, such as the leakage of internal network confidential information and the illegal

SQL Server queries 31 to 40 records in the table, and writes an SQL statement to output 31 to 40 records in the UserInfo table in case of discontinuous IDS (the database is SQL Server, and the Automatically increasing id is used as the primary key, note that the ID may not be consecutive )? According to the meaning of the question, the essence is to write paging queries: the number of entries per page: 10; the current page number
