Chero ani akaedza kumhanyisa muchina uri mugore anonyatsoziva kuti chiteshi cheRDP chakajairwa, kana chikasiiwa chakavhurika, chinongoerekana charwiswa nemafungu epassword brute force kuedza kubva kwakasiyana IP kero pasirese.
Munyaya ino ini ndicharatidza sei Iwe unogona kugadzirisa otomatiki mhinduro kune password brute simba nekuwedzera mutemo mutsva kune firewall. InTrust ndizvo yekuunganidza, kuongorora nekuchengetedza data isina kurongeka, iyo inotova nemazana ezvakafanotsanangurwa maitiro kune akasiyana marudzi ekurwiswa.
MuQuest InTrust unogona kugadzirisa zviito zvekupindura kana mutemo watanga. Kubva kumumiriri welog yekuunganidza, InTrust inogamuchira meseji nezve isina kubudirira mvumo yekuedza pane yebasa kana sevha. Kuti ugadzirise kuwedzera kero itsva dzeIP kufirewall, unofanirwa kutevedzera mutemo uripo wekuona zvibvumirano zvakakundikana uye wovhura kopi yayo kuti igadziriswe:
Zviitiko muWindows matanda zvinoshandisa chimwe chinhu chinonzi InsertionString. (iyi ndiyo isina kubudirira kupinda muhurongwa) uye iwe uchaona kuti minda yatiri kufarira yakachengetwa muInsertionString14 (Workstation Zita) uye InsertionString20 (Source Network Kero). ive isina chinhu, saka nzvimbo ino yakakosha kutsiva kukosha kubva kuSource Network Kero.
Izvi ndizvo zvinoita chinyorwa chechiitiko 4625:
