Te Whirihora i tētahi Pūoko hei Kohi Raraunga Rere

  • Ka hangaia e te pūoko ngā rekoata rere mai i te waka i runga i ōna atanga Ethernet mā te taunoa. E whakaaro ana tēnei whirihoranga taunoa kua honoa te pūoko ki tētahi tauranga SPAN, ki tētahi tauranga Ethernet whakaata rānei. Mena ka taea e ētahi atu taputapu i runga i tō whatunga te whakaputa rekoata rere, ka taea e koe te whirihora i te pūoko i roto i te web te atanga kaiwhakamahi o te tomokanga hei kohikohi i ngā rekoata rere mai i ēnei pūtake ka tuku atu ki te kapua.
  • Mena ka whakaputahia e ngā taputapu whatunga ngā momo rere rerekē, me whirihora te pūoko kia kohia ia momo mā runga i tētahi tauranga UDP rerekē. Mā tēnei ka taea hoki te whakatau raruraru
    easier. By default, the local sensor firewall (iptables) has ports 2055/UDP, 4739/UDP, and 9995/UDP open. If you want to use additional UDP ports, you must configure them in
    te web tomokanga.

You can configure collection of the following flow types in the web portal UI:

  • NetFlow v5 – Port 2055/UDP (open by default)
  • NetFlow v9 – Port 9995/UDP (open by default)
  • IPFIX – Port 4739/UDP (open by default)
  •  sFlow – Tauranga 6343/UDP

Kua whakaratohia e mātou ngā tauranga taunoa, engari ka taea ēnei te whirihora ki ō tauranga e pai ana ki a koe i roto i te web atanga kaiwhakamahi o te tomokanga.

Certain network appliances must be selected in the web te atanga kaiwhakamahi o te tomokanga i mua i te mahi tika:

  • Cisco Meraki – Tauranga 9998/UDP
  • Cisco ASA – Tauranga 9997/UDP
  • SonicWALL – Tauranga 9999/UDP

Meraki firmware version 14.50 aligns Meraki log export format with NetFlow format. If your Meraki device runs firmware version 14.50 or greater, configure your sensor with a Probe Type of NetFlow v9and a Source of Standard. If your Meraki device runs a firmware version older than 14.50, configure your sensor with a Probe Type of NetFlow v9and a Source of Meraki MX (below ver. 14.50).

Te Whirihora i ngā Pūoko mō te Kohinga Rere

  1. Takiuru ki te Secure Cloud Analytics hei kaiwhakahaere.
  2. Tīpakohia Tautuhinga > Pūoko.
  3. Click the Settings drop-down menu for the sensor you added.
  4. Kōwhiria te whirihora i te NetFlow/IPFIX.
    This option requires an up-to-date sensor version. If you do not see this option, select Help (?) > On-Prem Sensor Install to download a current version of the sensor ISO.
  5. Pāwhiritia Tāpirihia he Pūtirotiro Hou.
  6.  Kōwhiria he momo rere mai i te tahua taka-iho Momo Tirotiro.
  7.  Whakauruhia he nama Tauranga.
    Ki te hiahia koe ki te tuku i te Enhanced NetFlow ki tō pūoko, kia mōhio koe kāore te tauranga UDP e whirihorahia ana e koe i te tauranga e whirihorahia ana mō te Flexible NetFlow, te IPFIX rānei i roto i tō whirihoranga pūoko. Hei tauiraampWhirihorahia te tauranga 2055/UDP mō te Enhanced NetFlow, me te tauranga 9995/UDP mō te Flexible NetFlow. Tirohia te Aratohu Whirihoranga mō te Enhanced NetFlow mō ētahi atu kōrero.
  8. Kōwhiria he Kawa mai i te tahua taka-iho.
  9.  Kōwhiria he Pūtake mai i te tahua taka-iho.
  10.  Pāwhiritia Tiaki.

E 30 meneti pea te roa ka puta mai ngā whakahōutanga whirihoranga pūoko i roto i te tomokanga.

Hopukia ngā Mōkihi mai i te Pūoko
I ētahi wā, me manatoko pea e te Tautoko Cisco ngā raraunga rere e whiwhihia ana e te pūoko. Ka tūtohu mātou kia mahia tēnei mā te whakaputa i tētahi hopunga mōkihi o ngā rere. Ka taea hoki e koe te whakatuwhera i te hopunga mōkihi i roto i te Wireshark hei whakahou.view nga raraunga.

  1.  SSH ki roto i te pūoko hei kaiwhakahaere.
  2.  I te tohu, patohia te sudo tcpdump -Dā, pēhi i te Enter hei view he rārangi o ngā atanga. Tuhia te ingoa o te atanga Mana o tō pūoko.
  3. I te tohu, patohia te sudo tcpdump -i -n -c 100 “tauranga "-w" , whakakapi me tō ingoa atanga Mana, me te tau tauranga e rite ana ki ō raraunga rere kua whirihorahia, me me te ingoa mō te pcap i hangaia file, kātahi ka pēhi i te Enter. Ka whakaputa te pūnaha i tētahi pcap file me te ingoa kua tohua mō te rere o taua atanga, mā runga i te tauranga kua tohua.
  4. Takiuru atu i tō pūoko.
  5. Using an SFTP program, such as PuTTY SFTP (PSFTP), or WinSCP, log into the sensor.
  6. I te tohu, patohia te "get" , whakakapi me tō pcap i hangaia file ingoa, ka pēhi i te Enter hei whakawhiti i te file ki tō teihana mahi ā-rohe.

Analyze the Packet Capture in Wireshark

  1. Tikiake me te tāuta i te Wireshark, kātahi ka whakatuwhera i te Wireshark.
  2. Tīpakohia File > Whakatuwheratia, kātahi ka tīpako i tō pcap file.
  3. Tīpakohia Tātari > Wetewaehere Hei.
  4. Click + to add a new rule.
  5. Tīpakohia te CFLOW mai i te tahua taka-iho o nāianei, kātahi ka pāwhiri i te ĀE. Ka whakahōu te atanga kaiwhakamahi ki te whakaatu i ngā mōkihi e pā ana ki a NetFlow, IPFIX, sFlow rānei. Ki te kore he hua e puta mai, kāore te pcap i roto i ngā mōkihi e pā ana ki a NetFlow, ā, kua hē te whirihoranga o te kohinga raraunga rere i runga i te pūoko.
