Yuav ua li cas yog FTPS: ua hauj lwm hauv paus ntsiab lus thiab qhov sib txawv ntawm lub niaj zaus FTP

Cov niaj hnub Internet yog ib tug txheej ntawm computers kev cob cog rua rau txhua lwm yam los ntawm tshwj xeeb kev sib txuas lus twg. Yuav kom tso saib cov chaw siv twg HTTP, HTTPS, thiab rau cov kev pauv ntawm loj cov ntaub ntawv siv FTP, SFTP thiab FTPS. Cia peb kawm dab tsi hauv lub FTPS-neeg rau zaub mov. Peb kawm kuj yuav ua li cas siv nws.

Yuav ua li cas yog FTPS

Lub npe ntawm lub raws tu qauv yuav tsum tau muab faib ua ob qhov chaw: FTP + SSL los yog FTP + TLS (SSL advanced version). Thawj feem yog yooj yim thiab yog luv luv rau ntaub ntawv hloov raws tu qauv - cov ntaub ntawv hloov lwm lub tsev raws tu qauv. Qhov no txoj kev ntawm cov ntaub ntawv pauv txuj no yog tsis encrypted, li ntawd, cov ntaub ntawv xa mus ntawm FTP, ib qho yooj yim mus cuam tshuam thiab keej. Tej yam no yav tas los uas siv los ntawm hackers mus nyiag ib qho tseem ceeb cov ntaub ntawv los ntawm lub tuam txhab servers.

Yuav kom kho cov tsis muaj kev tiv thaiv ntawm cov ntaub ntawv, tsim FTPS raws tu qauv. Nws tag nrho cov kis cov ntaub ntawv yog thawj ua los ntawm SSL los yog TLS (encryption raws tu qauv), li ntawd, pab neeg no thiab hnab thaum lub sij hawm cov kev khiav tawm tsis muaj feem rau cov hom ntawm kev dag, piv txwv li, es tsis txhob ntawm «Nyob zoo» tuaj «GTYSL». Nyob rau hauv neeg rau zaub mov, raws li tag nrho cov code yog hloov dua siab tshiab rov qab mus rau lub Boolean kab zauv.

Peb yuav tau summed los ntawm cov nqe lus nug ntawm seb, FTPS - dab tsi yog qhov no thiab yog dab tsi nws zog. Qhov no ruaj ntseg FTP raws tu qauv. Tam sim no, cov kis ntawm cov ntaub ntawv, koj yuav tau nco ntsoov hais tias cov ntaub ntawv yuav nyob twj ywm paub xwb rau kev tso cai cov neeg siv. Tsis txhob xav yuam kev FTPS thiab SFTP, cov no yog cov sib txawv twg thiab ua hauj lwm nyob rau txawv tej ntsiab cai.

Yuav ua li cas mus rau cov hloov neeg rau zaub mov FTPS

Ib txhia tsis paub tias dab tsi lub FTPS-neeg rau zaub mov. Qhov no yog qhov computer uas stores ntaub ntawv, nws tej hauj lwm tib yam li cov FTP neeg rau zaub mov (hloov ntaub ntawv ntawm tus neeg thov). Tsuas yog rau lub fact tias tag nrho cov ntaub ntawv yog encrypted ua ntej hloov lwm lub tsev ntaub ntawv.

Yuav kom tiv thaiv ib cov ntaub ntawv neeg rau zaub mov hauv pliaj intrusion, koj yuav tsum tau tsim ib cov ntawv pov thawj. Yog hais tias koj siv Filezilla neeg rau zaub mov, ces qhov no, mus rau SSL / TLS chaw. Muaj yuav tsum tau tsim ib tug tshiab daim ntawv pov thawj, uas yuav tsum muaj xws li cov ntaub ntawv ntawm lub teb chaws code, lub npe ntawm lub koom haum, thiab lwm yam

Cov ntaub ntawv pov thawj yuav tsum tau free xwb los Filezilla los ntawm lwm yam kev pab. Rau hauv zos kev nkag txaus nws tus kheej-kos npe daim ntawv pov thawj, tab sis rau cov pej xeem kev ua ntawm cov kev ntsuas yuav tsis txaus, thiab cov ntaub ntawv pov thawj yuav tsum tau muas los ntawm ib tug pov thawj txoj cai.

Kev twb kev txuas FTPS

Yuav kom to taub zoo dua li cas FTPS, xav txog lub raws tu qauv ntawm tus qauv. Tsis zoo li FTP, thaum txuas tus neeg muas zaub tej zaum yuav thov kom ib tug ruaj ntseg kev twb kev txuas, e.g., ib tug nyias muaj nyias ib qhov chaw nres nkoj nrog encryption. Xav txog lub ntsiab lus ntawm cov ntawv pov thawj kev thov algorithm:

1. Tus neeg thov cov ntaub ntawv encryption (xa daim ntawv thov CSR-code).
2. Cov neeg rau zaub mov negotiates ib encryption algorithm thiab xa tus neeg SSL-daim ntawv pov thawj rau cov pej xeem tseem ceeb ntawm cov RSA-encryption.
3. Tus neeg nyeem cov ntaub ntawv los ntawm cov ntawv pov thawj thiab yog hais txog mus rau lub chaw uas muab cov ntawv pov thawj. Yog hais tias muaj ntawv pov thawj chaw thiab neeg rau zaub mov yog tib yam rau txhua tus lwm yam, lub xeem yog dhau thiab kev twb kev txuas ntxiv. Txwv tsis pub, cov kev twb kev txuas yog tu ncua thiab neeg rau zaub mov xa ib qho yuam kev code.
4. Yog hais tias lub xeem yog kev vam meej, tus neeg ua ib qho kev encrypted kev sib kho qhov tseem ceeb (cov ntaub ntawv encryption), thiab nws yuav raug xa mus rau lub neeg rau zaub mov. Nws yuav siv random tooj thiab RSA-encryption nrog pej xeem thiab lwm cov lag luam.
5. Cov neeg rau zaub mov tau txais cov yuam sij thiab decrypts nws. Nyob rau hauv lub neej yav tom ntej, qhov no tseem ceeb yog siv los encrypt tag nrho cov xa thiab tau txais cov ntaub ntawv.

Tom qab tau txais daim card kev sib kho tseem ceeb pib cov ntaub ntawv kis tau tus mob. Qhov tseem ceeb yog soj ntsuam txhua tshiab thov, tag nrho cov ntaub ntawv nyob rau hauv lub raws tu qauv FTPS-yog securely encrypted.

kev twb kev txuas

Vim TSL / SSL-daim ntawv pov yuav tau tshem ntawm phishing. Authentication tso cai rau lub browser paub raws nraim li cas nws cov ntaub ntawv yog xa mus rau hauv encrypted daim ntawv ncaj qha mus rau lub teev neeg rau zaub mov, thiab tsis mus rau hauv lub tsis ncaj ncees lawm computer. Nws yog tshwj xeeb tshaj yog ib qho tseem ceeb rau siv encryption thaum koj nkag mus rau tej ntaub ntawv, bank card numbers, thiab hais txog. N.

Kom paub tseeb tias koj yuav tsum tau siv cov ib cov ntaub ntawv pov thawj tsis tau tsuas yog nyob rau hauv lub neeg rau zaub mov, tab sis kuj nyob rau hauv tus neeg. Tej kev ceev faj yog ib qho tseem ceeb rau siv nyob rau hauv lub tsev txhab nyiaj, piv txwv li, cov kis ntawm ib qho tseem ceeb cov lus qhia txog cov qhua tuaj noj mov puag.

Txawm hais tias ib tug attacker yuav tsum tau txais cov ntaub ntawv los ntawm lub FTP raws tu qauv, lawv muaj tag nrho cov encrypted, thiab nyeem lawv cov ntsiab lus yog tsis yooj yim sua yam uas tsis muaj daim card RSA tseem ceeb.
