All of the hacker's actions were recorded by Snort during the invasion, and I used the Intrusion analysis data provided by www.whitehats.com. You can go to that query to all the d

There have been a lot of discussions on these two WEB-based attacks, such as how to launch attacks, their impact, and how to better compile and design programs to prevent these attacks. However, there is not enough discussion about how to detect these attacks. We use the popular open-source IDS Snort [ref 3] to construct a regular express

Security problems brought by Httptunnel Write here, we can imagine, if the administrator completely trust the firewall, then in a network with such a hidden trouble, what will happen? We can see that over the years, the reliance on firewalls has been included in the top 10 security issue of Sans. That being the case, a natural question arises: can this httptunnel behavior be found?

hundreds of protocols and media types; has a command-line version named Tethereal that resembles Tcpdump (a Network Protocol analysis tool under Linux). I have to say that ethereal has been plagued by a number of remotely exploitable vulnerabilities, so always upgrade it and use it sparingly in insecure networks or hostile networks, such as a security conferencing network. -------------------------------------------------------------------------------- #3

mode of OLED display is divided into passive matrix (PM-OLED) and active matrix (AM-OLED. The pixel size of the OLED display can be dozens to hundreds of micrometers, and the display resolution can reach more than 300 PPI (the number of pixels per inch ). Based on these advantages, OLED has been widely used in mobile electronic devices such as MP3 and mobile phones, and has gradually extended to large-size display fields such as PC monitors, laptops, and televisions.

However, there is not enough discussion about how to detect these attacks. We use the popular open-source IDS Snort [ref 3] to construct a regular expression based on the rules used to detect these attacks. Additionally,

There have been a lot of discussions about these two web-based attacks on the web, such as how to implement attacks, their impact, and how to better prepare and design programs to prevent these attacks. However, there is not enough discussion on how to detect these attacks. We use popular open source IDSSNORT[REF3 to build regular expressions based on the rules that detect these a

check data from captured files on an active network or disk. Users can view captured data interactively and deeply explore the details of the data packets you need to understand. This software has several features, including rich display filtering language and the ability to view structured data streams of a TCP session. It also supports a large number of protocols and media types, including a console version similar to tcpdump called tethereal. However, it is worth noting that it suffers from

Linux Firewall extension technology and intrusion detection implementation-Linux Enterprise applications-Linux server application information. The following is a detailed description. Abstract: This article introduces the implementation mechanism and extension technology based on the Linux netfilter/iptables architecture, and proposes the extension matching option to implement the firewall intrusion detection function, the expanded firewall can have intrusion detection functions like
