snort cookbook

When a Linux server is maliciously scanned by an external IP address, the system administrator usually deploys intrusion protection environments, such as snort. However, snort is complicated to deploy, sometimes we only need to prevent malicious scanning. In this case, you can use the PortSentry tool for simple implementation. Although PortSentry is no longer developed after it is acquired by Cisco, it does

Detection System (IDS), such as Snort, on each machine. It is foreseeable that IDS will notify you when an intrusion is occurring or has recently expired. After IDS is in place, you can add security at other levels, such as digital signature and encryption for your backup. Popular open-source tools, such as GNU Privacy Guard (GnuPG), OpenSSL, and ncrypt, support encryption of archival files through shell scripts, however, it is not recommended that y

Additional measures:We can add some devices and measures to further enhance system security.1. proxy firewall. For e

-performance computing system for distributed monitoring systems, such as clusters and grids. It is based on layered design, which uses a wide range of technologies such as XML data representation, portable data transfer, and RRDtool for data storage and visualization. It uses carefully designed data structures and algorithms to achieve very low concurrency between each node. It has been ported to a wide range of operating systems and processor architectures that are currently being used in thou

The packet capture tool has two advantages: one is snort and the other is tcpdump. this time, we don't mention snort. Although the tool is powerful, it is complicated, and tcpdump is relatively simple. Tcpdumpwindows and linux versions. You can download the linux version from www.tcpdump.org. after tcpdump is installed, run tcpdump: Two of the best packet capture tools are:

Today we will look at the following five most famous intrusion detection systems. 1.Snort: This is an open source IDs that almost everyone loves, which uses flexible rules-based language to describe communication, combining signatures, protocols, and detection methods for abnormal behavior. It has been updated extremely quickly, becoming the most widely deployed intrusion detection technology in the world and a standard for defensive t

One, how to learn Flex The best way to learn technology is to learn to use it while reading the official document while practicing in the project. But the official document is too boring, and if no one takes it, it doesn't know where to start the project from scratch. If there is such a person, from his first study to the end of learning, the process is recorded, the other people along his track to learn, will be easier to get started. For beginners, learning content if too difficult, difficul

Configuring a LAN network with pipework for Docker multi-container problem: Use the Pipework tool to specify the LAN IP address for the Docker container, the container cannot communicate with the LAN or the external network. Pipework is a docker network configuration tool developed by Docker's engineer Jérôme Petazzoni. Docker's own network functions are relatively simple and can not meet many complex application scenarios. Therefore, there are many open source projects to improve the network

Since the waterfall model is a common model, and we really need a concrete model to explore the similarities and differences between the traditional software development model and the ag

This article briefly introduces the principle of IP fragmentation, and analyzes in detail the principles and features of common IP fragmentation attacks based on the Snort packet capture results,Finally, some suggestions are provided to prevent IP Fragment attacks. I hope it will be helpful to better understand the IP protocol and some DoS attack methods. 1. Why is there IP fragmentation?-=The link layer has the maximum transmission unit MTU, which
