Ukusabalala kwe-COVID-19 kuphoqe izinkampani nezinhlangano eziningi ukuthi zisebenze zikude emzamweni wokugcina ibhizinisi lisebenza . Nakuba lesi sinyathelo sokuqapha siyisilinganiso esihle sempilo yabasebenzi kuyilapho kugcinwa ukukhiqiza, siphinde sivule amathuba engeziwe ukuze abahlaseli be-inthanethi baphumelele.
I-GLOBALEXPO ikukhuthaza ukuthi ufunde isihloko:
I-GLOBALEXPO: Imibukiso eku-inthanethi, amakholi wevidiyo, nezinkomfa endaweni eyodwa , lapho senza khona futhi inkomfa yevidiyo nevidiyo evikelekile. Isixazululo se-GLOBALEXPO
http://meet.globalexpo.online kunkundla evikelekile ye-Jitsi Meet sikunikeza u-100% ukuzethemba ukuthi akekho ongafinyelela idatha yakho, asikho isidingo sokubhalisa noma ukufaka noma yini. Uma unentshisekelo enkulu kulolu daba, kukhona futhi isihloko
, lapho siqhathanise inani lamathuluzi enkomfa ngevidiyo namathuluzi okushaya ngevidiyo.
I-GLOBALEXPO njengengxenye
yokuqalisa
#POMAHAME" href="http://www.pomahame.eu/"> #POMAHAME inikeza yonke inkampani ukuthi izethule emhlabeni we-inthanethi komunye wemibukiso eku-inthanethi noma ngisho nethuba lokuqhuba izingxoxo zevidiyo ezimfishane kanye nezingqungquthela zevidiyo mahhala ngokuphelele, ngokuvikelekile lapho nokwenzeka khona iphasiwedi, ngaphandle ukubhaliswa futhi ngaphandle kwemikhawulo. Ukubhaliswa kombukiso kuqukethe izinyathelo ezilula ezingenziwa yiwo wonke umuntu. Beka imizuzu engu-5 yesikhathi kulokhu kubhalisa futhi ubhalisele omunye wemibukiso yethu ye-inthanethi lapha > :
- Ukufinyelela Okungagunyaziwe kanye Nokuqhunyiswa Kwebhomu
- Ukuba sengozini kusofthiwe yenkomfa
- Ubuthakathaka namaphutha abangelwa ukuqaliswa nokusebenza kwesofthiwe yenkomfa
- Ukuhlaselwa kwe-DoS ne-DDoS ezingqungqutheleni zamavidiyo eziqhubekayo
Ukuqhuma kwamabhomu nokulalela
I-US FBI ixwayise ngabahlaseli abajoyine izingqungquthela zevidiyo ezisetshenziswe ekuqeqeshweni kwe-inthanethi noma imihlangano yebhizinisi ukuze babaphazamise. Nakuba ezinye izingqungquthela zaziphazanyiswa okuqukethwe okuhlekisayo kuphela, ezinye zaziqukethe izithombe zobulili ezingcolile noma ezinenzondo ezihlanganisa izinsongo nokuhlaselwa ngamazwi. Izigameko ezinjena zaqoshwa nasezikoleni eziphakeme zaseMelika, ngo umhlaseli ongaziwa ujoyine ukuqeqeshwa kwe-inthanethi kwe-teleconferencing ngenkundla ye-Zoom, okuphazamisa lonke ukuqeqeshwa.
Izinkundla zesimanje zenkomfa ngevidiyo ngokuvamile zivumela ukuxhumana okungaziwa ngaphandle kwegama, nekhamera nemakrofoni kuvaliwe, noma Ukudayela, noma okuvela emphakathini. inethiwekhi yocingo. Ababambiqhaza abanjalo bangalalela ukuxhumana ezingqungqutheleni ezinkulu zevidiyo.
Vulnerability Abuse
Ukuba sengozini akugwema ngisho nezinkundla zenkomfa ngevidiyo, nezinqubomgomo zokuphepha zesofthiwe, njengokufakwa ngokushesha kweziqephu zokuphepha, ziyasebenza nalapha. Isibonelo, izibuyekezo zikaMashi no-April zesisombululo senkomfa ngevidiyo se-Zoom esidumile ngokushesha zilungisa ubungozi obuningi obungaholela ekuhlukunyezweni. amathuba abahlaseli. Ukuba sengozini kunikwe amandla:
- lalela inkomfa ngevidiyo ngaphandle kolwazi lwabahlanganyeli ngenxa yokusetshenziswa kabi kokubethela ngasemaphethelweni
- hlunga amagama ayimfihlo endaweni ye-Windows ukuya kumhlaseli
- yeqa amalungelo esistimu yokusebenza lapho ufaka uhlelo lokusebenza
- faka ikhodi enobungozi engagunyaziwe
Nakuba ubungozi bulungisiwe kuplathifomu ye-Zoom, ukuhlasela kusaqhubeka njengoba abasebenzisi abaningi bengakalubuyekezanga uhlelo lokusebenza.

Ubuthakathaka namaphutha adalwe ukuqaliswa nokusebenza kwesofthiwe yenkomfa
Ilayisha ngayinye Ubuchwepheshe okufanele bufinyeleleke kusuka endaweni yangaphandle ukuya enhlanganweni bubuye bufike nezinguquko ekucushweni nasekusethweni kwengqalasizinda. Izinguquko ezibaluleke kakhulu zenzeka kumjikelezo wenhlangano kuma-firewall nezinye izici zokuphepha. Abalawuli bavame ukuvumela okuhlukile emithethweni elimaza ukuphepha. Ukuvulwa kwamachweba athile, kanye nezivumelwano ezivamile ezifana ne-RDP (lapho sibone khona ukwanda kwezivumelwano ezivulekile ze-RDP emasontweni asanda kwedlula) kanye ne-VNC, nokuntula kwabo ukuphepha kuvulela umhlaseli ongaphakathi enhlanganweni indlela. Ubuthakathaka futhi bungabangelwa ukuqaliswa okungalungile kwesixazululo senkomfa yevidiyo ngokwaso, ukufakwa kwezinguqulo eziphelelwe yisikhathi noma ukuvikeleka okwanele kweseva, okungaholela hhayi ekulimazeni kwayo kuphela, kodwa nasekungeneni komhlaseli kwenye inkampani. ingqalasizinda.
Abalawuli nabo benza izinto zibe lula ngokuvula ukuxhumana kwekheli le-IP kuzo zonke izimbobo lapho isixazululo senkomfa ngevidiyo sikhona, ukuze bangadingi ukubheka izimbobo ezithile lapho isisombululo sixhumana khona. Inqubo enjalo idingeka ngisho ngokuqondile ngezinye izixazululo. Nokho, lokhu kuholela engcupheni enkulu futhi akufanele neze yenzeke phakathi nokuqaliswa - noma ukuvula zonke izimbobo noma ukusebenzisa isisombululo esidinga inombolo enkulu yezimbobo ukuthi zivulwe.
Ukuhlasela kwe-DoS ne-DDoS
Enye indlela yokuphazamisa noma yokuvimbela ngokuphelele ikholi yenkomfa yevidiyo ukuhlasela ukusebenza kwangempela kwekholi yenkomfa yevidiyo eqhubekayo. Umhlaseli angakhetha ezinhlelweni eziningi zokuhlasela ingqalasizinda yesisulu ngokuqondile noma ahlasele ingqalasizinda ye-ISP lapho kwenzelwa khona ikholi yenkomfa yevidiyo.
Iningi lezinhlelo zokusebenza ezisebenzisa inkomfa ngevidiyo (isb. Zoom, Webex, Skype) ngokuvamile zihlinzeka ngethrafikhi yamafu, ngaphandle kwesidingo sokuba ngeyakho ingqalasizinda ukuze isebenze isevisi enjalo. Isixazululo sefu samakholi enkomfa ngevidiyo siyakhanga kakhulu, njengoba ngokombono wokusebenza siyisixazululo esishibhile, ngokombono womsebenzisi, inzuzo ijubane nokusebenziseka kalula. Kodwa-ke, imodi yefu yokusebenza nayo inobubi bayo obubalulekile - ukugcinwa kuyimfihlo kwezingxoxo akusoze kwaqinisekiswa, njengoba ukusebenza kunikezwa u-opharetha wangaphandle ongakwazi ukurekhoda futhi agcine izingcingo ngazinye. Ukuhlaselwa kwezinsizakalo zamafu nakho akuyona into ekhethekile - lapho isevisi isetshenziswa kakhulu, yilapho kukhanga kakhulu abahlaseli abaqondiwe.
Izincomo Zokuphepha ze-Videoconferencing
Amasistimu enkomfa ngevidiyo enza umsebenzi ube lula futhi angaba ithuluzi elihle lokugcina umsebenzi usebenza kahle. Kodwa-ke, inkomfa ngevidiyo engavikelekile ezinkundleni eziyingozi ibeka engcupheni enkulu yokuvikeleka. Ngakho-ke, i-National Cyber Security Center SK-CERT incoma:
- Sebenzisa isofthiwe eyaziwayo enegama elihle kanye nezici zokuphepha ezanele, njengokubethela kokuxhumana kwenethiwekhi, ukuqinisekiswa kwezinto ezimbili lapho ungena ngemvume, nokunye ukwenza inkomfa ngevidiyo
- Ikakhulukazi kuhulumeni, asincomi ukusebenzisa i-Zoom. Sincoma ukusebenzisa ezinye izindlela, eziphephile
- Sebenzisa isofthiwe ebuyekeziwe kuphela futhi ungalibali ukufaka uma izibuyekezo zokuphepha zikhishwa
- Vikela yonke ikholi yenkomfa yevidiyo ngephasiwedi ebanzi, okunzima ukuyiqagela. Ungasebenzisi igama-mfihlo elifanayo ezingcingweni eziningi zevidiyo zenkomfa
- Qinisekisa umhlanganyeli wengqungquthela yevidiyo ngayinye, okungcono ngokubheka nokuphatha okungenayo kwendawo yenkomfa yevidiyo (isici "sokulindwa")
- Yenza umhlangano ngevidiyo ube yimfihlo, ungabi sesidlangalaleni
- Ungabelani ngesixhumanisi senkomfa yevidiyo esidlangalaleni usebenzisa izinkundla zokuxhumana noma okunye okunjalo, yabelana kuphela ngesixhumanisi nabantu abathile okufanele babambe iqhaza kunkomfa yevidiyo
- Uma ufuna ukuxhumana nedatha ebucayi ne-teleconferences, yenza njalo ukuze ube yingxenye yolwazi. futhi ingxenye yasho phakathi nocingo futhi yathumela enye ingxenye yomlayezo ngolunye uhlelo lokusebenza
- Uma unezinsolo zokuphazamisa umhlangano wevidiyo, noma uma idivayisi yakho iziphatha ngendlela exakile, yazisa umqashi wakho nomuntu obhekele i-cybersecurity enhlanganweni yakho ngokushesha. />
Ngenxa yokuthi akuzona zonke izinkampani ezisungule umsebenzi ekhaya, azinayo ngisho nemihlahlandlela yezokuphepha nemithethonqubo yokuthi ungaya kanjani ehhovisi lasekhaya ngokombono wezokuphepha.
