Tawm lawv tus ID - yog dab tsi? Intrusion kom paub tias System (tawm lawv tus ID) raws li ib tug ua hauj lwm?

tawm lawv tus ID - yog dab tsi? Yuav ua li cas no system ua hauj lwm? System Intrusion kom paub tias - ib tug kho vajtse los yog software mus ntes tawm tsam thiab siab phem ua si. Lawv pab tes hauj lwm thiab lub computer systems muab lawv ib tug zoo rebuff. Yuav kom ua tau li no, tawm lawv tus ID sau ntaub ntawv los ntawm ntau yam system los yog network qhov chaw. Ces tus tawm lawv tus ID ntsuam nws los mus txiav txim hauv lub xub ntiag ntawm tawm tsam. Qhov tsab xov xwm yuav sim teb cov lus nug: "tawm lawv tus ID - dab tsi yog nws thiab yog dab tsi rau?"

Yuav ua li cas yog intrusion nrhiav kom tau tshuab (tawm lawv tus ID)

Cov ntaub ntawv systems thiab tes hauj lwm tas li raug sib tham isthawmnev hais-tawm tsam. Firewalls thiab antivirus muaj kev cuam tshuam tag nrho cov ntawm cov tawm tsam yog tsis txaus, vim hais tias lawv yeej tsuas muaj los tiv thaiv lub "pem hauv ntej lub qhov rooj" ntawm computer systems thiab tes hauj lwm. Lwm yam cov hluas, xav lawv tus kheej hackers, lossi scouring hauv internet nyob rau hauv kev tshawb fawb kev ncua nyob rau hauv kev ruaj ntseg tshuab.

Tsaug rau lub ntiaj teb dav Web ntawm lawv pov tseg ib tug ntau ntawm lig free kev cib software - tej Slammer, slepperov thiab zoo sib xws siab phem cov kev pab cuam. Service yog kev hackers yog sib tw tuam txhab uas muag rau neutralize txhua lwm yam. Yog li ntawd hais tias systems uas ntes ntxeem tau (intrusion nrhiav kom tau tshuab), - ib qho mob ceev yuav tsum tau. Tsis muaj zem hais tias txhua txhua hnub lawv yuav ua ntau lug siv.

ntsiab tawm lawv tus ID

Lub ntsiab ntawm tawm lawv tus ID muaj xws li:

• ntes subsystem, lub hom phiaj ntawm cov uas - tsub zuj zuj ntawm network txheej xwm los yog computer systems;
• tsom subsystem uas no ib tug kev sib tham isthawmnev nres thiab dubious kev ua si;
• cia rau khaws cia cov ntaub ntawv txog cov txheej xwm thiab cov kev tshwm sim ntawm kev soj ntsuam ntawm kev sib tham isthawmnev tawm tsam thiab tsis tau tso cai kev ua;
• tswj console uas tawm lawv tus ID yog tau teem tsis, saib xyuas hauv lub xeev ntawm lub network (los yog computer system), yuav tau siv cov lus qhia txog cov kev kuaj nres tsom xam subsystem thiab tsis raug cai ua.

Nyob rau hauv qhov tseeb, ntau yam yuav nug, "Yuav ua li cas yog txhais tawm lawv tus ID?" Neeg txhais lus los ntawm lus Askiv suab zoo li "system uas pom tus kub intruders."

Cov yooj yim paub tab kom daws tau qhov intrusion nrhiav kom tau system

Intrusion kom paub tias System muaj ob lub ntsiab hom phiaj: tsom xam ntawm cov ntaub ntawv qhov chaw thiab ib tug tsim nyog teb, raws li nyob rau hauv cov kev tshwm sim ntawm no tsom xam. Yuav kom ua tau cov kev pab raws qib tawm lawv tus ID system ua lub yam nram no:

• tsom kwm thiab sojntsuam neeg siv kev ua si;

• ntes ib qho yuam kev nyob rau hauv qhov system configuration;
• ntes tawm tsam pib thiab qhia.

Cov tawm lawv tus ID ua tsis tau nws:

• rau sau khoob nyob rau hauv network twg;
• nyiaj luag hauj lwm mus ua si nyob rau hauv cov kev tshwm sim ntawm tsis muaj zog qhia kom paub thiab authentication mechanisms tes hauj lwm los yog computer systems uas nws tsom kwm;
• Nws yuav tsum tau muab sau tseg tias tawm lawv tus ID yog tsis ib txwm paub daws teeb meem txuam nrog rau cov kev tawm tsam ntawm lub pob ntawv theem (pob ntawv-theem).

IPS (intrusion kev tiv thaiv system) - Txuas Ntxiv tawm lawv tus ID

IPS stands "intrusion kev tiv thaiv system." Qibsiab no, ntau haumxeeb tawm lawv tus ID ntau ntau yam. IPS tawm lawv tus ID systems yog reactive (nyob rau hauv sib piv rau lub niaj zaus). Qhov no txhais tau tias lawv yuav tsis tau tsuas yog qhia hais tias, cov ntaub ntawv thiab qhia txog tus nres, tab sis kuj yuav ua kev nyab xeeb zog. Cov zog muaj xws li tebchaw pib dua thiab thaiv cov hlab cov khoom tsheb packets. Lwm feature ntawm IPS yog hais tias lawv ua hauj lwm hauv internet thiab muaj peev xwm txiav thaiv tus nres.

Subspecies tawm lawv tus ID txoj kev rau cov saib xyuas

NIDS (ie tawm lawv tus ID, uas yog saib xyuas tag nrho cov network (network)) koom nyob rau hauv lub tsom xam ntawm cov tsheb khiav dhau subnets thiab tswj centrally. Tsis tu ncua kev kho ntawm ob peb saib xyuas NIDS peev xwm ua tau haum loj network loj.

Lawv ua hauj lwm nyob rau hauv promiscuous hom (ie saib tag nrho cov khoom packets, es tsis txhob ua nws xaiv) los ntawm muab piv subnet tsheb khiav mus paub tawm tsam nrog nws tsev qiv ntawv. Thaum ib tug nres yog qhia tau los yog kuaj tsis tau tso cai ua si, cov neeg khiav dej num yog xa ib lub tswb. Txawm li cas los, nws yuav tsum tau hais tias ib tug loj network uas muaj tsheb NIDS tej zaum yuav tsis tau tiv nrog tag nrho cov kev xeem ntaub ntawv packets. Yog li ntawd, muaj ib tug tau hais tias thaum lub sij hawm "maj teev", lawv yuav tsis muaj peev xwm mus paub txog lub nres.

NIDS (network-raws li tawm lawv tus ID) - cov no yog cov tshuab uas yooj yim kev mus rau hauv tshiab network topology ntau li ntau cawv rau lawv cov kev kawm, lawv tsis muaj, ua passive. Lawv tsuas tsau kaw thiab qhia, tsis zoo li reactive hom IPS tshuab uas tau sib tham saum toj no. Txawm li cas los, nws yuav tsum tau hais txog lub network raws li tawm lawv tus ID, qhov no yog ib qhov system uas yuav tsis tsom xam cov ntaub ntawv raug encryption. Qhov no yog ib tug tseem ceeb disadvantage vim hais tias ntawm qhov zuj zus kev taw qhia ntawm virtual private network (VPN) los encrypt cov ntaub ntawv yog qhia siv los ntawm cybercriminals mus tua.

NIDS kuj tsis tau txiav txim dab tsi tshwm sim raws li ib tug tshwm sim ntawm tus nres, nws tshwm sim los kev puas tsuaj los yog tsis. Tag nrho lawv muaj nyiaj - yog kho nws pib. Yog li ntawd, cov neeg khiav dej num yog yuam kom rov xyuas koj tus kheej txhua txhua nres cov ntaub ntawv kom paub tseeb tias tus nres ua tau zoo. Lwm tseem ceeb teeb meem yog tias NIDS tsis yog captures nres siv fragmented packets. Lawv yog cov tshwj xeeb tshaj yog txaus ntshai vim hais tias lawv muaj peev xwm cuam tshuam rau tej lag luam los ntawm NIDS. Qhov no txhais li cas rau tag nrho cov network los yog computer system, tsis muaj yuav tsum tau piav qhia.

HIDS (party intrusion nrhiav kom tau system)

HIDS (tawm lawv tus ID, monitoryaschie party (party)) pab xwb ib lub computer. Qhov no, ntawm chav kawm, muab ntau efficiency. HIDS analyzed ob hom ntawm cov ntaub ntawv: lub system cav thiab cov ntsiab ntawm cov operating system tshawb. Lawv ua ib tug snapshot ntawm system cov ntaub ntawv thiab muab piv rau nws nrog cov ua ntej lawm cov duab. Yog hais tias ib tug tseem ceeb ib qho tseem ceeb rau lub system cov ntaub ntawv tau raug hloov los yog tshem tawm, ces tus neeg saib xyuas xa ib tug tswb.

HIDS tseem ceeb kom zoo dua yog muaj peev xwm mus nqa tawm lawv ua hauj lwm nyob rau hauv ib qhov teeb meem nyob qhov twg network tsheb yog raug cipher. Qhov no yog tau ua tsaug rau lub fact tias yog rau tus tswv tsev (party-raws li) qhov chaw ntawm cov ntaub ntawv yuav tsum tsim ua ntej cov ntaub ntawv txais lawv tus kheej rau encryption los yog tom qab decryption rau cov lo lus uas tus tswv tsev.

Qhov tsis zoo ntawm no system xws li cov tau ntawm nws thaiv los yog txawm txwv tsis pub siv tej yam hom DoS-tawm tsam. Qhov teeb meem no yog hais tias ib co HIDS sensors thiab tsom xam cov cuab yeej muaj nyob rau ntawm tus tswv tsev, uas yog nyob rau hauv nres, uas yog, lawv kuj nres. Qhov tseeb hais tias cov kev pab yog HIDS fwjchim luj kawg nkaus uas nws ua hauj lwm lawv saib xyuas, dhau lawm, yuav tsis yog yuav hu ua ib tug ntxiv, vim hais tias nws lawm thiaj li lawv tsim tau.

Subspecies tawm lawv tus ID rau yuav ua li cas qhia hais tias tawm tsam

Txoj kev anomalies, kos npe tsom xam txoj kev thiab cov kev cai - xws subspecies yuav ua li cas kom paub tias tawm tsam yog lub tawm lawv tus ID.

Txoj kev kos npe rau tsom

Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv packets yog soj ntsuam txog kev nres kos npe. Qhov kos npe ntawm tus nres - nws sau raws nkaus Ii cov kev tshwm sim rau ib qho ntawm lub nrws, piav txog paub tawm tsam. Qhov no txoj kev yog heev zoo, vim hais tias thaum koj siv lub cuav ceeb toom ntawm tawm tsam no kuj tsis tshua muaj.

anomalies txoj kev

Nrog nws pab pom tsis raug cai kev ua nyob rau hauv cov network thiab party. Nyob rau lub hauv paus ntawm lub keeb kwm ntawm lub lag luam ntawm tus tswv tsev thiab tus network tsim tshwj xeeb profiles nrog cov ntaub ntawv hais txog nws. Ces tuaj mus ua si tshwj xeeb detectors uas tsom xam cov txheej xwm. Siv txawv algorithms lawv tsim ib tug tsom xam ntawm cov txheej xwm, muab piv rau lawv nrog rau cov "coob" nyob rau hauv lub profiles. Qhov uas tsis muaj yuav tsum tau noog ib tug lossis loj npaum li cas ntawm nres kos npe - ib tug meej ntxiv ntawm no txoj kev. Txawm li cas los, ib tug txiav txim tus naj npawb ntawm cuav alarms txog tus nres nrog atypical, tab sis nws yog heev tsim nyog network txheej xwm - qhov no yog nws undoubted rho tawm.

txoj cai txoj kev

Lwm txoj kev mus ntes tawm tsam yog ib txoj cai txoj kev. Lub essence ntawm nws - nyob rau hauv cov creation ntawm network kev ruaj ntseg cov kev cai, uas, piv txwv li, tej zaum yuav qhia cov tes hauj lwm ntawm hauv paus ntsiab lus ntawm lawv tus kheej thiab siv nyob rau hauv no raws tu qauv. Qhov no txoj kev yog pheej, tab sis qhov teeb meem yog nej ib tug yooj yim txheej txheem ntawm kev tsim ib database ntawm cov kev cai.

ID Systems yuav muab txhim khu kev qha kev tiv thaiv ntawm koj network thiab computer systems

Group ID Systems hnub no yog ib tug ntawm cov nyob rau hauv lub tshav pob ntawm kev ruaj ntseg tshuab kev ua lag luam thawj coj rau computer tes hauj lwm. Nws yuav muab rau koj txhim khu kev qha kev tiv thaiv tiv thaiv kev sib tham isthawmnev-villains. koj yuav tsis txhawj txog koj cov ntaub ntawv tseem ceeb los tiv thaiv ID Systems systems. Vim hais tias ntawm no koj yuav tsum tau txaus siab rau lub neej ntau vim hais tias koj muaj nyob rau hauv lub plawv yog ib tug me ntsis teeb meem.

ID Systems - neeg ua hauj lwm kev txheeb xyuas

Great pab neeg, thiab tseem ceeb tshaj, ntawm chav kawm - qhov no yog qhov tseeb cwj pwm ntawm kev tswj ntawm lub tuam txhab rau nws ua hauj lwm. Sawv daws (txawm lub fledgling beginners) muaj lub sij hawm rau kev loj hlob. Txawm li cas los, qhov no, ntawm chav kawm, koj yuav tsum qhia lawv tus kheej, thiab ces txhua yam yuav tig tawm.

Nyob rau hauv pab neeg no noj qab nyob zoo huab cua. Beginners yeej ib txwm nyob ib ncig ntawm lub tsheb ciav hlau thiab tag nrho cov yeeb yam. Tsis zoo sib txeeb yog tsis muaj. Neeg ua hauj lwm uas ua hauj lwm nyob rau hauv lub tuam txhab rau ntau xyoo, yog txaus siab los mus qhia tag nrho cov kev txhawb. Lawv yog cov phooj ywg, txawm tsis muaj ib tug hint ntawm nqis los nrog teb cov feem ntau plhom moj lus nug inexperienced neeg ua hauj lwm. Nyob rau hauv kev, los ntawm ua hauj lwm nyob rau hauv lub ID Systems ib co qab ntxiag cwj pwm txawv.

Cwj pwm tswj pleasantly txaus siab. Tsis tas li ntawd txaus siab uas nyob ntawm no, obviously, yog tau mus ua hauj lwm nrog cov neeg ua hauj lwm, vim hais tias cov neeg ua hauj lwm yog tiag tiag mas sib phim. Neeg ua hauj lwm yuav luag unequivocal: lawv xav tias nyob rau kev ua hauj lwm nyob rau hauv tsev.
