Munyaya dzekuchengetedzwa kwenetiweki, Intrusion Detection System (IDS) neIntrusion Prevention System (IPS) zvine basa guru. Chinyorwa chino chichaongorora zvakadzama tsananguro dzadzo, mabasa adzo, misiyano yadzo, uye mamiriro ekushandiswa kwadzo.
Chii chinonzi IDS (Intrusion Detection System)?
Tsanangudzo yeIDS
Sisitimu yeKuona Kupindira kweVashandi (Intrusion Detection System) chishandiso chekuchengetedza chinoongorora nekuongorora traffic yenetiweki kuti chione mabasa kana kurwiswa kwakaipa. Inotsvaga masiginecha anoenderana nemapatani ekurwiswa anozivikanwa nekuongorora traffic yenetiweki, marogi ehurongwa, nerumwe ruzivo rwakakodzera.
Mashandiro anoita IDS
IDS inoshanda zvikuru nenzira dzinotevera:
Kuonekwa kweSiginicha: IDS inoshandisa siginecha yakafanotaurwa yemaitiro ekurwiswa kuti ifananise, yakafanana nema scanner evhairasi ekuona mavhairasi. IDS inopa yambiro kana traffic iine zvinhu zvinoenderana nema siginecha aya.
Kuonekwa kweAnomaly: IDS inoongorora mashandiro enetwork uye inozivisa painoona maitiro akasiyana zvakanyanya nemaitiro akajairika. Izvi zvinobatsira kuona kurwiswa kusingazivikanwe kana kutsva.
Kuongorora Maitiro Ekushandisa: IDS inoongorora mashandisirwo eprotocol dzenetwork uye inoona maitiro asingaenderane neprotocol dzakajairwa, nokudaro ichiona kurwiswa kunogona kuitika.
Mhando dzeIDS
Zvichienderana nekuti vanoendeswa kupi, IDS inogona kukamurwa kuita mhando mbiri huru:
MaID eNetwork (NIDS): Yakaiswa mu network kuti iongorore traffic yese inofamba ne network. Inogona kuona zvese network uye transport layer attacks.
IDS yeHost (HIDS): Inoiswa pahost imwe chete kuti iongorore mashandiro esystem pahost iyoyo. Inonyanya kutarisa pakuona kurwiswa kwehost-level senge malware uye maitiro asina kujairika emushandisi.
Chii chinonzi IPS (Intrusion Prevention System)?
Tsanangudzo yeIPS
Masisitimu ekudzivirira kupinda muchivande zvishandiso zvekuchengetedza zvinotora matanho ekudzivirira kana kudzivirira kubva mukurwiswa kunogona kuitika mushure mekuzviona. Kana tichienzanisa neIDS, IPS haisi chishandiso chekutarisa nekuzivisa chete, asiwo chishandiso chinogona kupindira nekudzivirira njodzi dzinogona kuitika.
Mashandiro anoita IPS
IPS inodzivirira sisitimu iyi nekuvharira vanhu vane njodzi vanofamba nepa network. IPS inoshanda zvikuru inosanganisira:
Kudzivirira Kurwiswa Kwemotokari: Kana IPS ikaona vanhu vanogona kurwiswa, inogona kutora matanho ekukasika kudzivirira vanhu ava kuti vasapinde munetwork. Izvi zvinobatsira kudzivirira kupararira kwekurwisa uku.
Kugadzirisazve Mamiriro Ekubatana: IPS inogona kugadzirisa mamiriro ekubatana ane chekuita nekurwiswa kunogona kuitika, zvichimanikidza murwisi kuti agadzirise kubatana uye nokudaro zvichikanganisa kurwiswa.
Kugadzirisa Mitemo yeFirewall: IPS inogona kuchinja mitemo yefirewall kuti ivhare kana kubvumira mhando dzakasiyana dzetraffic kuti dzienderane nemamiriro ezvinhu ekutyisidzira panguva chaiyo.
Mhando dzeIPS
Kufanana neIDS, IPS inogona kukamurwa kuita mhando mbiri huru:
Network IPS (NIPS): Inoiswa mu network kuti iongorore uye idzivirire kubva mukurwiswa kwe network yese. Inogona kudzivirira kubva mukurwiswa kwe network layer uye transport layer.
IPS yeMubati (HIPS): Inoiswa pamudziviriri mumwe chete kuti ipe dziviriro chaiyo, inonyanya kushandiswa kudzivirira kurwiswa kwemudziviriri kwakadai se malware uye kushandisa zvisina kunaka.
Ndeupi musiyano uripo pakati peIntrusion Detection System (IDS) neIntrusion Prevention System (IPS)?
Nzira Dzakasiyana dzeKushanda
IDS inzira yekutarisa isina kupindira, inonyanya kushandiswa pakuona uye kuratidza njodzi. Kusiyana neizvi, IPS inoshanda nekukurumidza uye inokwanisa kutora matanho ekudzivirira kubva pakurwiswa kunogona kuitika.
Kuenzanisa Njodzi Nemhedzisiro
Nekuda kwekusashanda zvakanaka kweIDS, inogona kusaonekwa kana kusaonekwa zvakanaka, nepo kudzivirira IPS kuchigona kukonzera kurwiswa kwakanaka. Pane chikonzero chekuyera njodzi nekushanda zvakanaka pakushandisa masisitimu ese ari maviri.
Kusiyana kweKutumira uye Kugadzirisa
IDS inowanzo chinjika uye inogona kuiswa munzvimbo dzakasiyana munetwork. Kusiyana neizvi, kuiswa uye kurongeka kweIPS kunoda kuronga kwakanyatsonaka kudzivirira kukanganiswa kwetraffic yakajairika.
Kushandiswa Kwakabatana kweIDS neIPS
IDS neIPS zvinobatsirana, nekutarisa nekupa yambiro dzeIDS uye IPS ichitora matanho ekudzivirira kana zvichidikanwa. Kubatanidzwa kwadzo kunogona kugadzira tambo yekudzivirira ine kuchengetedzwa kwenetiweki yakakwana.
Zvakakosha kugadzirisa mitemo, masiginecha, uye ruzivo rwekutyisidzira rweIDS neIPS nguva nenguva. Kutyisidzira kwepaindaneti kuri kuramba kuchichinja, uye kugadziridzwa kwenguva yakakodzera kunogona kuvandudza kugona kwesystem kuona njodzi itsva.
Zvakakosha kugadzirisa mitemo yeIDS neIPS kuti ienderane nemamiriro ezvinhu chaiwo enetwork uye zvinodiwa nesangano. Nekugadzirisa mitemo yacho, kururama kwesystem kunogona kuvandudzwa uye zviratidzo zvenhema uye kukuvara kweushamwari kunogona kuderedzwa.
IDS neIPS dzinofanira kukwanisa kupindura kunjodzi dzinogona kuitika munguva chaiyo. Mhinduro inokurumidza uye yakarurama inobatsira kudzivirira varwisi kuti vasakonzere kukuvara kwakanyanya mu network.
Kuramba uchitarisa traffic ye network uye kunzwisisa maitiro akajairwa etraffic kunogona kubatsira kuvandudza kugona kwekuona zvisina kunaka kweIDS uye kuderedza mukana wekuti pave nenhema.
