Raws li cov IP intercoms sab nraum zoov sai sai hloov cov txheej txheem analog ib txwm muaj, lawv tab tom txhais dua tshiab txog peb txoj kev tswj hwm kev nkag mus thiab kev ruaj ntseg ntawm lub qhov rooj pem hauv ntej. Txawm li cas los xij, tom qab qhov yooj yim ntawm kev nkag mus rau thaj chaw deb thiab kev sib txuas hauv huab muaj kev pheej hmoo cyber loj hlob thiab feem ntau tsis tau kwv yees. Yog tsis muaj kev tiv thaiv zoo, lub IP intercom sab nraum zoov tuaj yeem ua lub qhov rooj zais rau hauv koj lub network tag nrho.
Kev Loj Hlob Sai ntawm Cov Txheej Txheem IP Intercom Sab Nraud
Kev hloov ntawm analog mus rau IP-based video intercoms tsis yog qhov xaiv tau lawm - nws tshwm sim txhua qhov chaw. Yam uas ib zaug yog lub buzzer yooj yim txuas nrog cov xov hlau tooj liab tau hloov zuj zus mus ua ib qho IP sab nraum zoov uas muaj networked tag nrho khiav ib lub operating system embedded, feem ntau yog Linux-based. Cov khoom siv no xa cov suab, video, thiab cov teeb liab tswj hwm ua cov ntaub ntawv packets, ua haujlwm zoo li cov khoos phis tawj txuas nrog internet mounted rau ntawm phab ntsa sab nraud.
Vim li cas IP Intercoms nyob txhua qhov chaw
Qhov kev thov kom nkag siab yooj yim. Cov txheej txheem video intercom sab nraum zoov niaj hnub muaj cov yam ntxwv uas ua rau kev yooj yim thiab kev tswj hwm zoo dua qub:
-
Kev nkag mus rau hauv xov tooj ntawm tes tso cai rau cov neeg siv teb cov qhov rooj los ntawm txhua qhov chaw ntawm cov apps smartphone
-
Kev khaws cia cov yeeb yaj kiab hauv huab ua rau cov ntaub ntawv qhua ntxaws ntxaws muaj thaum xav tau
-
Kev sib koom ua ke ntse txuas cov intercoms nrog teeb pom kev zoo, kev tswj kev nkag, thiab cov tshuab ua haujlwm hauv tsev
Tiam sis qhov yooj yim no los nrog kev pauv pauv. Txhua lub cuab yeej txuas nrog lub network uas muab tso rau sab nraum zoov ua rau muaj kev phom sij rau IoT kev ruaj ntseg.
Kev Pheej Hmoo Cyber Backdoor: Yam Uas Feem Ntau Cov Kev Teeb Tsa Tsis Tau Ua
Feem ntau lub tshuab intercom sab nraum zoov (IP intercom) raug teeb tsa sab nraum lub firewall, tab sis txuas ncaj qha rau lub network sab hauv. Qhov no ua rau nws yog ib qho ntawm cov chaw tawm tsam zoo tshaj plaws rau cov neeg ua txhaum cai hauv cyber.
Kev Nkag Mus Rau Lub Cev Lub Cev Los Ntawm Cov Chaw Nres Ethernet Uas Pom Tseeb
Muaj ntau lub chaw teeb tsa uas tso cov qhov (ports) Ethernet uas pom tag nrho tom qab lub vaj huam sib luag intercom. Yog tias lub ntsej muag raug tshem tawm, tus neeg tawm tsam tuaj yeem:
-
Txuas ncaj qha rau hauv lub network cable uas nyob
-
Bypass perimeter kev ruaj ntseg cov khoom siv
-
Pib kev luam theej sab hauv yam tsis tau nkag mus rau hauv lub tsev
Yog tsis muaj kev ruaj ntseg ntawm qhov chaw nres tsheb Ethernet (802.1x), qhov "kev tawm tsam ntawm qhov chaw nres tsheb" no yuav yooj yim heev.
Kev Tawm Tsam SIP Tsis Tau Encrypted thiab Man-in-the-Middle
Cov IP intercoms sab nraum zoov uas pheej yig lossis qub dhau lawm feem ntau xa suab thiab video siv cov txheej txheem SIP uas tsis tau encrypted. Qhov no qhib lub qhov rooj rau:
-
Kev mloog cov lus sib tham ntiag tug
-
Rov ua dua cov kev tawm tsam uas siv cov cim qhib dua
-
Kev cuam tshuam daim ntawv pov thawj thaum lub sijhawm teeb tsa kev hu xov tooj
Kev siv SIP encryption siv TLS thiab SRTP tsis yog xaiv tau lawm - nws yog qhov tseem ceeb.
Kev Siv Botnet thiab Kev Koom Tes DDoS
Cov intercoms uas tsis ruaj ntseg zoo yog cov hom phiaj tseem ceeb rau IoT botnets xws li Mirai. Thaum raug cuam tshuam lawm, lub cuab yeej tuaj yeem:
-
Koom nrog kev tawm tsam DDoS loj
-
Siv bandwidth thiab ua rau koj lub network qeeb
-
Ua rau koj tus IP pej xeem raug blacklisted
Qhov no ua rau DDoS botnet mitigation yog qhov tseem ceeb rau kev xa tawm IP intercom sab nraum zoov.
Cov Yuam Kev Kev Ruaj Ntseg Feem Ntau Hauv Kev Siv IP Intercom Sab Nraud
Txawm tias cov khoom siv zoo tshaj plaws los ua lub luag haujlwm thaum cov kev coj ua cybersecurity yooj yim raug tsis quav ntsej.
Cov Passwords Uas Tsis Tau Ua Ntej thiab Cov Ntawv Pov Thawj Hoobkas
Tsis txhob hloov cov ntaub ntawv pov thawj ntawm lub Hoobkas yog ib txoj hauv kev ceev tshaj plaws uas yuav ua rau koj tsis tswj tau ib lub cuab yeej. Cov neeg hlau tsis siv neeg yuav tshuaj xyuas cov ntaub ntawv nkag mus rau hauv lub cuab yeej tas li, ua rau lub kaw lus puas tsuaj hauv ob peb feeb tom qab kev teeb tsa.
Tsis Muaj Kev Faib Tawm Hauv Network
Thaum cov intercoms sib koom tib lub network li cov khoom siv ntiag tug lossis cov servers lag luam, cov neeg tawm tsam tau txais lub sijhawm txav mus rau sab. Yog tsis muaj kev faib network rau cov khoom siv ruaj ntseg, kev ua txhaum ntawm lub qhov rooj pem hauv ntej tuaj yeem nce mus rau hauv kev sib tsoo network tag nrho.
Cov Firmware Qub Lawm thiab Kev Tsis Saib Xyuas Patch
Muaj ntau lub intercoms sab nraum zoov uas siv tau ntau xyoo yam tsis tau hloov kho firmware. Txoj kev "set-and-forget" no ua rau cov qhov tsis zoo uas paub lawm tsis tau kho thiab yooj yim siv.
Kev vam khom rau huab tsis muaj kev tiv thaiv
Cov platform intercom uas siv huab ua rau muaj kev pheej hmoo ntxiv:
-
Kev ua txhaum cai ntawm lub server tuaj yeem ua rau cov ntaub ntawv pov thawj thiab cov ntaub ntawv video raug tshaj tawm
-
Cov APIs tsis muaj zog tuaj yeem xau cov yeeb yaj kiab nyob
-
Kev tsis muaj internet tuaj yeem ua rau kev tswj hwm kev nkag mus tsis tau zoo
Cov Kev Xyaum Zoo Tshaj Plaws rau Kev Ruaj Ntseg Sab Nraud IP Intercoms
Yuav kom tiv thaiv cov IP intercoms sab nraum zoov kom tsis txhob dhau los ua cyber backdoors, lawv yuav tsum tau muaj kev nyab xeeb zoo li lwm qhov kawg ntawm lub network.
Cais cov Intercoms siv VLANs
Tso cov intercoms rau ntawm VLAN tshwj xeeb txwv kev puas tsuaj txawm tias lub cuab yeej raug cuam tshuam los xij. Cov neeg tawm tsam tsis tuaj yeem txav mus rau sab nraud rau cov kab ke rhiab heev.
Siv 802.1x Authentication
Nrog 802.1x qhov chaw nres nkoj authentication, tsuas yog cov khoom siv intercom uas tau tso cai thiaj li txuas tau rau lub network. Cov laptops tsis tau tso cai lossis cov khoom siv rogue yuav raug thaiv cia li.
Qhib Kev Nkag Mus Tag Nrho
-
TLS rau SIP signaling
-
SRTP rau cov suab thiab video streaming
-
HTTPS rau kev teeb tsa hauv web
Kev siv encryption ua kom cov ntaub ntawv raug cuam tshuam tsis nyeem tau thiab siv tsis tau.
Ntxiv Kev Tshawb Nrhiav Kev Ua Phem Lub Cev
Cov tswb ceeb toom txog kev cuam tshuam, kev ceeb toom tam sim ntawd, thiab kev kaw qhov chaw nres nkoj tsis siv neeg ua kom ntseeg tau tias kev cuam tshuam lub cev ua rau muaj kev tiv thaiv tam sim ntawd.
Cov Lus Kawg: Kev Ruaj Ntseg Pib Ntawm Lub Qhov Rooj Pem Hauv Ntej
Cov IP intercoms sab nraum zoov yog cov cuab yeej muaj zog - tab sis tsuas yog thaum siv tau zoo xwb. Kev kho lawv zoo li lub tswb qhov rooj yooj yim es tsis yog cov khoos phis tawj sib txuas ua ke ua rau muaj kev pheej hmoo loj heev hauv cyber. Nrog kev encryption, kev faib network, kev lees paub, thiab kev tiv thaiv lub cev, cov IP intercoms sab nraum zoov tuaj yeem muab kev yooj yim yam tsis muaj kev cuam tshuam kev ruaj ntseg.
