上面只列举出了一些常用的 payload detection rule option,更多的关键词查阅 snort_manual 8.3.5.2 通用规则选项(General rule option) sid snort id,这个关键字被用来识别 snort 规则的唯一性。sid 的范围是如下分配的: <100 #保留做将来使用 100-1000,000 #包含在snort发布包中 >1000,000 #作为本地规则使用 ...
第二个数字是 Snort ID (SID), 也可以叫Signature ID. SID 的清单可以在 Snort 文件目 etc/gen-msg.map 查看. Rule-based SID 通过 sid 选项 直接写入规则(rules)文件. 第三个数字是 revision ID. 这个数字主要用来当签名使, 通过 rev 选项, 每次执行触发规则(rendition of the rule)的时候都会增加. 1....

这个嘛。你应该去看介绍snort规则的书，或者是官方手册snort manual.snort的每一条规则分为规则头和规则体。例如第一条规则：alert udp $EXTERNAL_NET any -> $HOME_NET 161 (msg:"SNMP missing community string attempt"; content:"|04 00|"; depth:15; offset:5; metadata:service snmp; refe...
alert tcp $HTTP_SERVERS $HTTP_PORTS -> $EXTERNAL_NET any (msg:"ATTACK-RESPONSES 403 Forbidden"; flow:from_server,established; content:"HTTP/1.1 403"; depth:12; classtype:attempted-recon; sid:1201; rev:7;) 实际上这条规则现在包含在了较新的 Snort 版本中,但是如果您已经安装了 Snort,那么确...

( done in a later step). To make sure that barnyard2 knows that the rule we created with unique identifier 10000001 has the message ”ICMP Test Detected”, as well as some other information (please seethis blog postfor more information). We add the following line to the/etc/snort/sid-...
sid:Snort规则id … 这条规则看字面意思就很容易理解。Snort就是利用规则来匹配数据包进行实时流量分析,网络数据包记录的网络入侵检测/防御系统(Network Intrusion Detection/Prevention System),也就是NIDS/NIPS。 0x01 SNORT目录结构 建议将Snort的目录结构配置成如下: ...
sid-msg.map This file contains a mapping of alert messages to Snort rule IDs. Thesid-msg.mapfile is used for post-processing/displaying events. threshold.conf This file is useful in helping to reduce the number of alerts for noisy rules, and to suppress rules for IPs or groups of IPs....
