Rule options form the heart of Snort’s intrusion detection engine combining ease of use with power and flexibility. All Snort rule options are separated from each other using a semicolon (;). Rule option keywords are separated from their arguments with a colon (:). GENERAL RULE OPTIONS Messa...
关键字ruletype后面跟随动作的名称,连个大括号中是实际的动作定义,类似于c语言中的函数。例如:我们定义一个叫做smb_db_alert的动作,用来向workstation.list中的主机发送SMB告警,同时在MySQL中的"snort"数据库记录,如下所示: ruletype smb_db_alert { typealert outputalert_smb: workstation.list outputdatabase:l...
--process-all-events Process all triggered events in group order, per Rule Ordering configuration. Default stops after first group. --pid-path <path> Specify the path for Snort's PID file. 为SnortPID文件指定路径。 --create-pidfile Create PID file, even when not in Daemon mode. 创建PID文件。
The rule options section contains the appropriate detection keywords, which describe the way to inspect the packet. This section also includes options for what to display when the alert is triggered. The chapter provides the knowledge needed to create efficient rules without hindering the Snort ...
sudo nano /etc/snort/snort.conf在配置文件中,设置网络变量、规则路径等。例如: ipvar HOME_NET 192.168.1.0/24ipvar EXTERNAL_NET anyinclude $RULE_PATH/local.rules 步骤4:创建检测规则 Snort检测规则定义了要检测的网络行为。可以在/etc/snort/rules/local.rules文件中添加自定义规则。
ALERT tcp any any -> 192.168.0.1 80 (msg:"My Custom Rule"; content:"GET /admin.php"; sid:3001; rev:1;) ``` 该规则将在任何源IP地址和源端口号的数据包中匹配到目标IP地址为192.168.0.1,目标端口号为80,并且包含字符串"GET /admin.php"的数据包时触发警报。
include $RULE_PATH/local.rules #取消注释,在545行左右 测试snort #sudo snort -T -c /etc/snort/snort.conf -i eth0 #eth0是网卡,可用ifconfig查看 结果如下: Rules Engine: SF_SNORT_DETECTION_ENGINE Version 3.1 <Build 1> Preprocessor Object: SF_S7COMMPLUS Version 1.0 <Build 1> ...

将var PREPROC_RULE_PATH的值改为/etc/snort/rules/preproc_rules。 将var REFERENCE_RULES_PATH的值改为/etc/snort/rules。 将var FILE_SIGNING_ENABLED的值改为on。 将var FILE_SIGNING_KEY的值改为你的密钥路径。如果还没有密钥,你需要生成一个。可以使用以下命令生成一个自签名证书: openssl req -new -...
