all unnecessary rules, otherwise it will damage the performance and generate some false warnings. Another important policy is to run Snort in the confidential mode, that is, to listen to a network interface without an IP address. On interfaces without IP addresses, such as ifconfig eth0 up, run Snort with the-I option, such as snort? I eth0. it is also possible that if your Network Manager program is running in the system, it will "help" display the ports that have not been configured, therefor

Note: Device extension: DEVICE_EXTENSION is another important data structure related to device objects. Device object: the object of a device. It is the data structure of the driver in the kernel. Each driver has a unique DRIVER_OBJECT, And the IO Manager uses the driver object to represent each device driver. This diagram des

Pwn2Own and discuss the solution to Linux hacking

At the just-concluded Pwn2own conference, almost all systems were ridiculed by hackers, hackers proved by their actions that the manufacturers did nothing ". However, hackers are hackers. Linux is a relatively secure system in normal times. Of course, many friends may encounter the problem of server hacking. Related materials are collected and sorted out here, here I have found a solution to Linux Server hacking. I hope you will see a lot of GAINS. If you have installed all the correct patches,

Reading Notes _ windows APIHook Technology

First, we will introduce rootkits. rootkits is a high-end hacker technology that can run in the kernel state. It is at the same level as anti-virus software and is difficult to detect and clear. In Windows, most processes depend on three subsystems: Win32, POSIX, and OS/2. These subsystems contain a set of well-described APIs, most programs depend on these APIs, so they are an excellent target for rootkit. Let's take a look at the process in which an

How to flat hacker attacks on Linux servers

And because the rogue software using thread injection technology has been incorporated into the memory space of Normal programs, even firewall programs will not intercept, so that users can freely access and exit

OSSEC checks the BUG and reproduction of the netstat rookit Module

How xti9erOSSEC checks netstat rookit is: Use netstat to view the port and bind this port for comparison. If the port cannot be bind, it indicates that the port is occupied. If netstat does not find this port, it indicates that netstat is replaced by rootkit. The idea is good. However, the difference between the two causes false positives. For example, some temporary ports are enabled after run_netstat, And the return value of conn_port is turn, a fal
