Pankhani ya chitetezo cha netiweki, Intrusion Detection System (IDS) ndi Intrusion Prevention System (IPS) zimagwira ntchito yofunika kwambiri. Nkhaniyi ifufuza mozama matanthauzidwe awo, maudindo awo, kusiyana kwawo, ndi zochitika zomwe amagwiritsa ntchito.
Kodi IDS (Intrusion Detection System) ndi chiyani?
Tanthauzo la IDS
Dongosolo Lozindikira Kulowerera ndi chida chachitetezo chomwe chimayang'anira ndikusanthula kuchuluka kwa magalimoto pa netiweki kuti chizindikire zochitika kapena ziwopsezo zomwe zingachitike. Limafufuza zizindikiro zomwe zikugwirizana ndi machitidwe odziwika bwino a ziwopsezo pofufuza kuchuluka kwa magalimoto pa netiweki, zolemba zamakompyuta, ndi zina zofunika.
Momwe IDS imagwirira ntchito
IDS imagwira ntchito makamaka m'njira zotsatirazi:
Kuzindikira Zizindikiro: IDS imagwiritsa ntchito siginecha yodziwika bwino ya machitidwe owukira pofananiza, mofanana ndi ma scanner a ma virus kuti azindikire ma virus. IDS imachenjeza pamene magalimoto ali ndi zinthu zomwe zikugwirizana ndi ma siginecha awa.
Kuzindikira Zolakwika: IDS imayang'anira ntchito ya netiweki yanthawi zonse ndipo imachenjeza anthu akazindikira njira zomwe zimasiyana kwambiri ndi zomwe zimachitika nthawi zonse. Izi zimathandiza kuzindikira ziwopsezo zosadziwika kapena zatsopano.
Kusanthula kwa Protocol: IDS imasanthula kagwiritsidwe ntchito ka ma protocol a netiweki ndikupeza machitidwe omwe sagwirizana ndi ma protocol wamba, motero kuzindikira ziwopsezo zomwe zingatheke.
Mitundu ya IDS
Kutengera komwe akugwiritsidwa ntchito, IDS ikhoza kugawidwa m'magulu awiri akuluakulu:
Ma ID a pa Netiweki (NIDS): Imayikidwa mu netiweki kuti iwunikire magalimoto onse omwe akuyenda mu netiweki. Imatha kuzindikira kuukira kwa netiweki komanso kwa mayendedwe.
Ma ID Othandizira (HIDS): Imayikidwa pa host imodzi kuti iwunikire zochitika za dongosolo pa host imeneyo. Imayang'ana kwambiri kuzindikira ziwopsezo za host-level monga pulogalamu yaumbanda ndi khalidwe losazolowereka la ogwiritsa ntchito.
Kodi IPS (Intrusion Prevention System) ndi chiyani?
Tanthauzo la IPS
Machitidwe Oletsa Kulowerera ndi zida zachitetezo zomwe zimatenga njira zodzitetezera kuti ziletse kapena kuteteza ku ziwopsezo zomwe zingachitike mutazizindikira. Poyerekeza ndi IDS, IPS si chida chongoyang'anira ndi kuchenjeza, komanso chida chomwe chingalowererepo ndikuletsa ziwopsezo zomwe zingachitike.
Momwe IPS imagwirira ntchito
IPS imateteza dongosololi mwa kuletsa magalimoto oipa omwe akuyenda mu netiweki. Mfundo yake yayikulu yogwirira ntchito ndi iyi:
Kuletsa Magalimoto Oukira: Pamene IPS yazindikira kuchuluka kwa anthu omwe angaukire, imatenga njira mwachangu kuti anthuwa asalowe mu netiweki. Izi zimathandiza kupewa kufalikira kwa kuukiraku.
Kukonzanso Mkhalidwe wa Kulumikizana: IPS ikhoza kukhazikitsanso mgwirizano womwe umagwirizana ndi kuukira komwe kungachitike, zomwe zimapangitsa wowukirayo kukhazikitsanso kulumikizanako motero kusokoneza kuukirako.
Kusintha Malamulo a Firewall: IPS ikhoza kusintha malamulo a firewall kuti aletse kapena kulola mitundu inayake ya magalimoto kuti igwirizane ndi zoopsa zomwe zimachitika nthawi yeniyeni.
Mitundu ya IPS
Mofanana ndi IDS, IPS ikhoza kugawidwa m'magulu awiri akuluakulu:
IPS ya pa intaneti (NIPS): Imayikidwa mu netiweki kuti iyang'anire ndikuteteza ku ziwopsezo pa netiweki yonse. Imatha kuteteza ku ziwopsezo za netiweki ndi zoyendera.
IPS Yogwira Ntchito (Ma HIPS): Imayikidwa pa kampani imodzi yokha kuti ipereke chitetezo cholondola, makamaka chomwe chimagwiritsidwa ntchito poteteza ku ziwopsezo za seva monga pulogalamu yaumbanda ndi kugwiritsa ntchito molakwika.
Kodi pali kusiyana kotani pakati pa Intrusion Detection System (IDS) ndi Intrusion Prevention System (IPS)?
Njira Zosiyanasiyana Zogwirira Ntchito
IDS ndi njira yowunikira yopanda phokoso, yomwe imagwiritsidwa ntchito makamaka pozindikira ndi kuchenjeza. Mosiyana ndi zimenezi, IPS ndi yothandiza ndipo imatha kuchitapo kanthu kuti iteteze ku ziwopsezo zomwe zingachitike.
Kuyerekeza Zoopsa ndi Zotsatira
Chifukwa cha kusachitapo kanthu kwa IDS, ikhoza kuphonya kapena kukhala ndi zotsatira zabodza, pomwe chitetezo cha IPS chingayambitse moto wochezeka. Pali kufunika kolinganiza zoopsa ndi magwiridwe antchito pogwiritsa ntchito njira zonse ziwiri.
Kusiyana kwa Kutumiza ndi Kusintha
IDS nthawi zambiri imakhala yosinthasintha ndipo imatha kutumizidwa m'malo osiyanasiyana mu netiweki. Mosiyana ndi zimenezi, kutumizidwa ndi kukonzedwa kwa IPS kumafuna kukonzekera mosamala kwambiri kuti tipewe kusokoneza magalimoto wamba.
Kugwiritsa Ntchito IDS ndi IPS Mogwirizana
IDS ndi IPS zimathandizana, ndi kuyang'anira ndi kupereka machenjezo a IDS ndipo IPS imatenga njira zodzitetezera mwachangu ngati pakufunika kutero. Kuphatikizana kwa izi kungapangitse mzere wokwanira wa chitetezo cha pa intaneti.
Ndikofunikira kusintha malamulo, masaini, ndi nzeru za ziwopsezo za IDS ndi IPS nthawi zonse. Ziwopsezo za pa intaneti zikusintha nthawi zonse, ndipo zosintha zanthawi yake zitha kupititsa patsogolo luso la makina kuzindikira ziwopsezo zatsopano.
Ndikofunikira kusintha malamulo a IDS ndi IPS kuti agwirizane ndi malo enieni a netiweki komanso zofunikira za bungwe. Mwa kusintha malamulowo, kulondola kwa dongosololi kungawongoleredwe ndipo zotsatira zabodza komanso kuvulala kochezeka kungachepe.
IDS ndi IPS ziyenera kuyankha ku ziwopsezo zomwe zingachitike nthawi yomweyo. Kuyankha mwachangu komanso molondola kumathandiza kupewa owukira kuti asawononge kwambiri netiweki.
Kuyang'anira nthawi zonse kuchuluka kwa magalimoto pa intaneti komanso kumvetsetsa momwe magalimoto amayendera kungathandize kukulitsa luso lozindikira zolakwika za IDS ndikuchepetsa kuthekera kwa zotsatira zabodza.
