ʻO ka mea i hoʻāʻo e holo i ka mīkini uila i loko o ke ao ua ʻike maikaʻi ʻo ia i kahi awa RDP maʻamau, inā wehe ʻia, e kokoke koke e hoʻouka ʻia e nā nalu o ka password brute force hoʻāʻo mai nā ʻano IP address a puni ka honua.
Ma kēia ʻatikala e hōʻike wau pehea e Hiki iā ʻoe ke hoʻonohonoho i kahi pane maʻalahi i ka password brute force ma ka hoʻohui ʻana i kahi lula hou i ka pā ahi. ʻO InTrust no ka hōʻiliʻili ʻana, ka nānā ʻana a me ka mālama ʻana i nā ʻikepili i kūkulu ʻole ʻia, i loaʻa i nā haneli o nā hopena i koho mua ʻia i nā ʻano hoʻouka kaua.
Ma Quest InTrust hiki iā ʻoe ke hoʻonohonoho i nā hana pane ke hoʻomaka ʻia kahi lula. Mai ka luna hōʻiliʻili lāʻau, loaʻa iā InTrust kahi memo e pili ana i ka hoʻāʻo ʻana i ka hoʻāʻo ʻole ʻia ma kahi keʻena hana a i ʻole kikowaena. No ka hoʻonohonoho ʻana i ka hoʻohui ʻana i nā leka uila IP hou i ka pā ahi, pono ʻoe e kope i kahi lula maʻamau no ka ʻike ʻana i nā mana ʻae ʻole he nui a wehe i kahi kope o ia mea no ka hoʻoponopono ʻana:
Hoʻohana nā hanana i loko o nā lāʻau Windows i kahi mea i kapa ʻia ʻo InsertionString. (ʻaʻole i kūleʻa kēia i ka ʻōnaehana) a e ʻike ʻoe ua mālama ʻia nā māla a mākou e makemake ai ma InsertionString14 (Workstation Name) a me InsertionString20 (Source Network Address). e hakahaka, no laila he mea nui kēia wahi e hoʻololi i ka waiwai mai Source Network Address.
ʻO kēia ke ʻano o ka kikokikona o ka hanana 4625:
