RuleCat

GO开发而成,用于NIDS HIDS 分析的规则引擎,使用WorkerPool 高性能检测,支持正则、子串、等于,支持多字段 "和" "或" 检测, 支持频率检测, 支持自定义函数检测,自定义函数可以满足几乎所有数据类型的检测

输入:

Kafka(Json)

输出:

E-Mail,ES, Kafka,Json 文件

计划添加:

Redis,Rabbitmq 的输入

规则编写

state:     enable                        //  规则状态 enable   disable 
rule_id :  sqli_get_01                   //  规则ID
rule_tag:  sqli                          //  规则标签
rule_name: sqli_get_select               //  规则名

rule_type:  or                           //  or 类型规则代表,detect_list里面命中任何一条,算命中
rule_type:  and                          //  and 类型规则代表,detect_list里面命中所有规则,算命中
rule_type:  frequency_or                 //  frequency_or 类型规则代表,detect_list里面命中任何一条,且以key计数,单位时间内达到计数值上限算命中
rule_type:  frequency_and                //  frequency_and 类型规则代表,detect_list里面命中所有规则,且以key计数,单位时间内达到计数值上限算命中


detect_list:

  - field : conn.conn_state              //  字段
    type: re                             //  正则
    rule: S0                             //  具体规则
    ignorecase: false                    //  是否忽略大小写

  - field : conn.proto                   //  字段
    type: equal                          //  等于
    rule : tcp                           //  具体规则

  - field : conn.conn_state              // 字段
    type: in                             // 判断是否为子串
    rule : S0                            // 具体规则
 
  - field: conn.ip                       // 字段
    type: customf                        // 自定义函数
    rule: CheckIP                        // 自定义函数名 


key : conn.id\.orig_h                     // 只有frequency 类型的有,以此字段对应数据为key计数

time_interval:                            // 只有frequency 类型的有,代表 10s内出现 10次
   second: 10                  
   times: 10


threat_level : high                       // 威胁等级
auth : njcx86                             // 作者
info : about sql injection attack         // 注释

取字段对应的方式如下:

{
  "name": {"first": "Tom", "last": "Anderson"},
  "age":37,
  "children": ["Sara","Alex","Jack"],
  "fav.movie": "Deer Hunter",
  "friends": [
    {"first": "Dale", "last": "Murphy", "age": 44, "nets": ["ig", "fb", "tw"]},
    {"first": "Roger", "last": "Craig", "age": 68, "nets": ["fb", "tw"]},
    {"first": "Jane", "last": "Murphy", "age": 47, "nets": ["ig", "tw"]}
  ]
}
"name.last"          >> "Anderson"
"age"                >> 37
"children"           >> ["Sara","Alex","Jack"]
"children.#"         >> 3
"children.1"         >> "Alex"
"child*.2"           >> "Jack"
"c?ildren.0"         >> "Sara"
"fav\.movie"         >> "Deer Hunter"
"friends.#.first"    >> ["Dale","Roger","Jane"]
"friends.1.last"     >> "Craig"

目前支持四种输出:

output:
    es:
      enabled : true  
      es_host : ["http://10.10.116.177:9201"]
      version : 7

    kafka:
      enabled : true
      server : ["172.21.129.2:9092"]
      topic: nids-alert
      group_id: nids-alert


    email:
      enabled: false
      email_host: smtp.qq.com
      email_smtp_port: 465
      email_from: 123456@qq.com
      email_username: 123456@qq.com
      email_pwd: 123456


    json:
      enabled : true
      path : /tmp/
      name : nids-alert.log
