[分享]開放原始碼的入侵偵測系統：Snort
- 主題發起人 夢夢狐
- 開始日期
會只偵測第一張網路卡......
在Linux平臺，沒有手動指定的話會只偵測eth0
而在Windows平臺，則一定要設參數設定要偵測的網路卡
Snort所認定的網路卡順序請用 [作業系統槽]\snort\bin\snort -W 查看
不過建議還是手動設定要偵測的網路卡比較好。有些小問題如果沒指定網路卡就會跑出來
Snort因為很消耗電腦效能(流量大的時候)，所以預設是只能偵測一張的
-------------------------------------------------------------------------------------
還有......很對不起的是，要問問題可以，
但本討論串自今日起笨笨狐不接受PM發問......
請直接像這篇一樣用回覆的發問，謝謝。
有幾位網友為了問我問題而註冊，發了PM，結果笨笨狐撥時間回覆發了回去，
之後在幾個月後，去查看PM回條功能結果發現那些人到現在都沒有開來看過Orz
(好心酸呀......炸)
有沒有說感謝在下並不是那麼重視，但至少不要問了就跑沒用到
別人的解答連開來看都不開結果浪費別人的時間......
為了那些問題，有時笨笨狐還要開電腦去重新摸一次耶=w=|||
(嗯......不過前面幾位有回覆的人笨笨狐也在這裡說聲謝謝喔~>w<)
再來~~大大能不能說明一下ACID裡面的功能~~
簡單介紹~~像如何看~~
又有啥功能之類的~~
因為>"< 比我視窗版的防火牆還難懂~~~
我用netlimiter 2 pro看的連線IP在ACID裡面看不到>"<
可是又有正確運作~~怪怪~~~
那要如何做~~才可以監視兩張網卡??
我現在再用Vmware + Red Hat Enterprise AS 4 有用兩張網卡~~
之後做NAT~~~
所以有想要用監視兩張網卡的方法~~
再來~~能否用到遠端管理~~
是不是我在MYSQL裡面的帳號snort 和 acid 裡面加入遠端的連線即可??
因為我還沒有裝~~就先簡略問一下~~
我正在準備套件跟安裝方法~~
拜託大大指點一下囉~~

最後編輯：
大大~~~我先安裝
snort-2.6.1.2-1.RHEL4.i386.rpm
在安裝
snort-mysql-2.6.1.2-1.RHEL4.i386.rpm
結果都會出現說我沒有安裝
libmysqlclient
可是我安裝AS4時是用最大安裝~~
我看MYSQL跟HTTP裡面我都有安裝捏~~~
怎會這樣?

這是執行後的狀態~~
為啥MYSQL都連不上??我都照做了~~~
很對不起，目前手邊電腦Linux重灌掉了(Sorry......)
所以可能暫時還沒辦法實做......有些問題回的不是很詳細請見諒。
1.在Win平台個人是這樣啦，每次都是用手動開......因為主要還是在Linux上用
可以試試看寫批次檔放在啟動資料夾？和人借過本書裡面好像是把程式作成服務吧，但笨笨狐並沒有詳細看......
在Linux上，如果用RPM裝的話裝成功就會在服務那邊出現了
設定成每次開機就啟動就好。
2.因為Snort是個入侵偵測系統，只會把有危險性的封包紀錄起來
所以正常時在ACID是看不到東西的(因為通過的都是正常的封包)
在偵測到惡意封包後畫面會有紅色的長條表示百分比
然後數字方面是可以選的，選了以後會跳到那個數字所代表的區域
(TCP、UDP還是ICMP，或著是左邊的各項top 10)
按封包的名稱就可以看到攻擊的名稱，ICRT當初發布這個安全性警報的網頁(有的不會有)、檔頭(來源及目的IP之類)
以及下面是整個封包的全部二進位內容XD
至於多網卡的應用，這裡是有寫......不過在手邊沒電腦的情況下沒辦法確定是否可行@ @|||
http://forum.icst.org.tw/phpBB2/viewtopic.php?t=2974
一般而言最常用的還是裝在多臺電腦(因流量問題.....)，然後結果放在同一個遠端MySQL資料庫裡
3. & 4.
你用的作業系統所使用的MySQL使用者端程式(libmysqlclient.so.xx)
有裝是沒錯啦，但是版本和在下的可能不一樣......
因為在下是使用CentOS，可能AS4是使用不一樣的終端了。
RPM裡的編譯完成檔和閣下的作業系統不同可能配不起來，所以可能要用tar.gz原始碼安裝
(或著先改用FC5版的snort裝看看......)
想請問一下閣下會不會用tar.gz原始碼編譯的方式安裝程式......因為這種裝法就不會有這種相容性問題了！@w@
不過比較麻煩Orz

實用上使用ACID時請小心喔，可能要用Apache把ACID網頁改成鎖上密碼
不然會被偷看......XD
ACID是使用php架構，運行起來其實就像網頁一樣......
所以可能暫時還沒辦法實做......有些問題回的不是很詳細請見諒。
1.在Win平台個人是這樣啦，每次都是用手動開......因為主要還是在Linux上用
可以試試看寫批次檔放在啟動資料夾？和人借過本書裡面好像是把程式作成服務吧，但笨笨狐並沒有詳細看......
在Linux上，如果用RPM裝的話裝成功就會在服務那邊出現了
設定成每次開機就啟動就好。
2.因為Snort是個入侵偵測系統，只會把有危險性的封包紀錄起來
所以正常時在ACID是看不到東西的(因為通過的都是正常的封包)
在偵測到惡意封包後畫面會有紅色的長條表示百分比
然後數字方面是可以選的，選了以後會跳到那個數字所代表的區域
(TCP、UDP還是ICMP，或著是左邊的各項top 10)
按封包的名稱就可以看到攻擊的名稱，ICRT當初發布這個安全性警報的網頁(有的不會有)、檔頭(來源及目的IP之類)
以及下面是整個封包的全部二進位內容XD
至於多網卡的應用，這裡是有寫......不過在手邊沒電腦的情況下沒辦法確定是否可行@ @|||
