windows 防火墙日志 
In the process of filtering Internet traffic, all firewalls have some type of logging feature that documents how the firewall handled various types of traffic. These logs can provide valuable information like source and destination IP addresses, port numbers, and protocols. You can also use the Windows Firewall log file to monitor TCP and UDP connections and packets that are blocked by the firewall. 在过滤Internet流量的过程中，所有防火墙都具有某种类型的日志记录功能，该功能记录了防火墙如何处理各种类型的流量。 这些日志可以提供有价值的信息，例如源和目标IP地址，端口号和协议。 您还可以使用Windows防火墙日志文件来监视TCP和UDP连接以及被防火墙阻止的数据包。 为什么和何时使用防火墙日志记录 验证新添加的防火墙规则是否正常运行，或者如果它们未能按预期运行，则对其进行调试。 确定Windows防火墙是否是应用程序失败的原因-使用防火墙日志记录功能，您可以检查禁用的端口开放，动态端口开放，使用推送和紧急标志分析丢弃的数据包以及分析发送路径上的丢弃的数据包。 帮助和识别恶意活动-使用防火墙日志记录功能，您可以检查网络内是否发生了任何恶意活动，尽管您必须记住它没有提供跟踪活动来源所需的信息。 如果您发现反复尝试从一个IP地址(或一组IP地址)访问防火墙和/或其他高配置系统失败，那么您可能需要编写一条规则来删除该IP空间中的所有连接(请确保IP地址没有被欺骗)。 来自内部服务器(例如Web服务器)的传出连接可能表明某人正在使用您的系统对其他网络上的计算机发起攻击。 如何生成日志文件 (Why and When Firewall Logging is Useful To verify if newly added firewall rules work properly or to debug them if they do not work as expected. To determine if Windows Firewall is the cause of application failures — With the Firewall logging feature you can check for disabled port openings, dynamic port openings, analyze dropped packets with push and urgent flags and analyze dropped packets on the send path. To help and identify malicious activity — With the Firewall logging feature you can check if any malicious activity is occurring within your network or not, although you must remember it does not provide the information needed to track down the source of the activity. If you notice repeated unsuccessful attempts to access your firewall and/or other high profile systems from one IP address (or group of IP addresses), then you might want to write a rule to drop all connections from that IP space (making sure that the IP address isn’t being sp |
