說(shuō)明:大家平時(shí)對(duì)Linux服務(wù)器安全主要是對(duì)系統(tǒng)用戶的檢查，登陸服務(wù)器IP檢查，以及防火墻狀態(tài)檢查！
1.需要把正確系統(tǒng)用戶名存儲(chǔ)在/root/liu_shell/local_user.txt文件中，然后進(jìn)行比較!
2.對(duì)登陸IP判斷是不是以192.168.1和192.168.2開(kāi)頭的IP為正常IP!
3.判斷iptables狀態(tài)!
復(fù)制代碼 代碼如下:

for xx in file01:
mmm.append(re.split(':',xx)[0])
file01.close()
file02=file('/root/liu_shell/new_user.txt','w')
for yy in mmm:
file02.write('%s%s' %(yy,fuhao))
file02.close()
