Pankhani ya chitetezo cha pa intaneti, njira yodziwikiratu (IDS) ndi intrusion prevention system (IPS) imakhala ndi gawo lalikulu. Nkhaniyi iwunika mozama matanthauzidwe awo, maudindo, kusiyana kwawo, komanso momwe amagwiritsidwira ntchito.
Kodi IDS(Intrusion Detection System) ndi chiyani?
Tanthauzo la IDS
Dongosolo la Intrusion Detector ndi chida chachitetezo chomwe chimayang'anira ndikuwunika kuchuluka kwa anthu pamanetiweki kuti adziwe zoopsa zomwe zingachitike kapena kuwukira. Imasaka masiginecha omwe amafanana ndi zomwe zimadziwika kuti akuwukira powunika kuchuluka kwa magalimoto pamanetiweki, zolemba zamakina, ndi zina zambiri.
Momwe IDS imagwirira ntchito
IDS imagwira ntchito makamaka m'njira izi:
Kuzindikira Siginecha: IDS imagwiritsa ntchito siginecha yodziwikiratu yofananira, yofanana ndi makina ojambulira ma virus pozindikira ma virus. IDS imakweza chenjezo pamene magalimoto ali ndi zinthu zomwe zimagwirizana ndi siginechazi.
Kuzindikira kwa Anomaly: IDS imayang'anira zoyambira za zochitika zapaintaneti wamba ndikukweza zidziwitso ikazindikira machitidwe omwe amasiyana kwambiri ndi machitidwe wamba. Izi zimathandiza kuzindikira kuukira kosadziwika kapena kwatsopano.
Kusanthula kwa Protocol: IDS imasanthula kagwiritsidwe ntchito ka ma protocol a netiweki ndikuzindikira machitidwe omwe sagwirizana ndi ma protocol wamba, motero amazindikira kuukira komwe kungachitike.
Mitundu ya IDS
Kutengera komwe amatumizidwa, IDS ikhoza kugawidwa m'mitundu iwiri ikuluikulu:
Network IDS (NIDS): Amayikidwa mu netiweki kuti aziwunika kuchuluka kwa magalimoto pamaneti. Imatha kuzindikira kuukira kwa netiweki ndi zoyendera.
Host IDS (HIDS): Amayikidwa pa gulu limodzi kuti liwunikire zomwe zikuchitika pagululo. Imayang'ana kwambiri pakuzindikira kuti akuwukira ngati pulogalamu yaumbanda komanso machitidwe achilendo a ogwiritsa ntchito.
Kodi IPS(Intrusion Prevention System) ndi chiyani?
Tanthauzo la IPS
Njira zopewera kulowerera ndi zida zachitetezo zomwe zimachitapo kanthu kuti ziyimitse kapena kuziteteza ku zomwe zingachitike mutazizindikira. Poyerekeza ndi IDS, IPS sikuti ndi chida chowunikira ndi kuchenjeza, komanso chida chomwe chitha kulowererapo mwachangu ndikuletsa ziwopsezo zomwe zingachitike.
Momwe IPS imagwirira ntchito
IPS imateteza dongosololi poletsa mwachangu magalimoto oyipa omwe akuyenda pa intaneti. Mfundo yake yayikulu yogwirira ntchito ikuphatikiza:
Kuletsa Attack Magalimoto: IPS ikazindikira kuchuluka kwa anthu omwe akuwukira, imatha kuchitapo kanthu mwachangu kuti ma trafficwa asalowe mu netiweki. Izi zimathandiza kupewa kufalikira kwa chiwonongekocho.
Kukhazikitsanso State Connection: IPS ikhoza kukonzanso malo olumikizana omwe angagwirizane ndi kuwukira, kukakamiza wowukirayo kukhazikitsanso kulumikizana ndikusokoneza kuwukira.
Kusintha Malamulo a Firewall: IPS imatha kusintha malamulo oteteza ma firewall kuti atseke kapena kulola mitundu ina ya magalimoto kuti igwirizane ndi zochitika zenizeni.
Mitundu ya IPS
Mofanana ndi IDS, IPS ikhoza kugawidwa m'magulu awiri:
Network IPS (NIPS): Amayikidwa pa netiweki kuti aziwunika ndikudzitchinjiriza pakuwukiridwa pamaneti onse. Itha kuteteza motsutsana ndi kusanjikiza kwa netiweki komanso kuukira kwakusanjikiza zoyendera.
Host IPS (HIPS): Imayikidwa pa gulu limodzi kuti lipereke chitetezo cholondola, chomwe chimagwiritsidwa ntchito poteteza anthu omwe ali nawo monga pulogalamu yaumbanda ndi masukusi.
Kodi pali kusiyana kotani pakati pa Intrusion Detection System (IDS) ndi Intrusion Prevention System (IPS)?
Njira Zosiyanasiyana Zogwirira Ntchito
IDS ndi njira yowunikira, yomwe imagwiritsidwa ntchito kwambiri pozindikira komanso alamu. Mosiyana ndi izi, IPS ndiyokhazikika ndipo imatha kuchitapo kanthu kuti itetezedwe ku ziwopsezo zomwe zingachitike.
Kuyerekeza Zowopsa ndi Zotsatira
Chifukwa cha kusasamala kwa IDS, ikhoza kuphonya kapena zabodza, pomwe chitetezo chokhazikika cha IPS chingayambitse moto wochezeka. Pakufunika kulinganiza chiopsezo ndi kuchita bwino mukamagwiritsa ntchito machitidwe onsewa.
Kusiyana kwa Ma Deployment and Configuration
IDS nthawi zambiri imakhala yosinthika ndipo imatha kutumizidwa m'malo osiyanasiyana pa intaneti. Mosiyana ndi izi, kutumizidwa ndi kusinthidwa kwa IPS kumafuna kukonzekera mosamala kuti apewe kusokoneza magalimoto abwinobwino.
Kugwiritsa Ntchito Integrated kwa IDS ndi IPS
IDS ndi IPS zimathandizirana, ndikuwunika kwa IDS ndikupereka zidziwitso komanso IPS ikuchita zodzitchinjiriza pakafunika kutero. Kuphatikiza kwa iwo kumatha kupanga mzere wokwanira wachitetezo chachitetezo pa intaneti.
Ndikofunikira kusinthira pafupipafupi malamulo, siginecha, ndi nzeru zowopseza za IDS ndi IPS. Ziwopsezo za pa cyber zikusintha nthawi zonse, ndipo zosintha zapanthawi yake zitha kupititsa patsogolo luso la makina ozindikira zowopseza zatsopano.
Ndikofunikira kusintha malamulo a IDS ndi IPS kuti agwirizane ndi malo ochezera a pa intaneti komanso zofunikira za bungwe. Mwa kusintha malamulowo, kulondola kwa dongosololi kumatha kukonzedwa bwino ndipo zabwino zabodza komanso kuvulala kochezeka kumatha kuchepetsedwa.
IDS ndi IPS ziyenera kuyankha paziwopsezo zomwe zingachitike munthawi yeniyeni. Kuyankha mwachangu komanso molondola kumathandiza kuletsa omwe akuukira kuti asawononge zambiri pamaneti.
Kuwunika mosalekeza za kuchuluka kwa magalimoto pa netiweki komanso kumvetsetsa momwe magalimoto alili abwinobwino kungathandize kuwongolera luso la IDS lozindikira bwino komanso kuchepetsa kuthekera kwa bodza.
