OSSEC project is supported by Trend Micro Company. Project Link: https://github.com/ossec/ossec-hids11, PassivednsPassivedns is able to collect DNS records passively, thus enabling the functions of incident handling assistance, network security monitoring, and digital forensics. The software can be configured to read PCAP (i.e. packet capture) files and output DNS data as log files or extract data traffic

The security of Wireless LAN has always been one of our key issues. So how can we achieve comprehensive protection? First, we need to conduct a comprehensive analysis of the network security mechanism to see what causes the danger. Next we will conduct a wireless LAN security analysis. 1. First, determine the

For most enterprise LAN, routers have become one of the most important security devices in use. Generally, most networks have a primary access point. This is the "virtual border router" that is usually used with a dedicated firewall ". After proper configuration, the edge router can block almost all the most stubborn bad elements out of the network. If you want to, this type of router also allows good peopl

attacks: Also known as port scanning or vulnerability scanning. Attackers use data collection to obtain information about the attacked network. Generally, they must first perform port scanning, then conduct a vulnerability scan. By using tools such as NMAP, attackers can obtain all public IP addresses on the attacker's network, and the prediction results of each
