6 Yakanakisisa Kukuvadza Zvishandiso Zveshandisi neIndaneti

Hapana munhu anoda ruwaya rwavanokwanisa kuti vave chinangwa chevashandi vane utsinye vachiedza kuba nhengo dzekambani kana kukonzera kukanganisa kusangano. Kuti udzivise izvozvo, iwe unoda kuwana nzira dzekuvimbisa kuti kune nzira shomanana dzingaita kuti vapinde. Uye izvi zvinopedzerwa muchikamu nekuita kuti mumwe nomumwe achinetseka pamusangano wako unozivikanwa, akataurirwa, uye akagadziriswa. Uye kune avo vanotambura izvo zvisingagoni kugadziriswa, pane chimwe chinhu chiripo kuti chidzikise. Nhanho yekutanga yakajeka; iyo kuongorora network yako kune avo vasina kusimba. Iri ibasa reimwe rudzi rwemapurogiramu anonzi kusvibiswa kuongorora mashandisi. Nhasi, tiri kuongorora 6 yakanakisisa yekutsvaga matanho ekushandisa uye software.

Ngatitange nokutaura pamusoro pekunetseka kwehutano-kana kuti tinofanira kutaura zvisingakwanisi-uye edza kutsanangura zvavari. Tichazotevera kurukura nezvekutengesa kushandiswa zvishandiso. Ticharondedzera kuti ndiani anovada uye nei. Uye sezvo kubvisa kunetseka kunongova chinhu chimwe chete chekuchengetedzwa kwekutambura-kunyange chakakosha-izvi ndizvo zvatichataura nezvotevera. Zvadaro, tichaona kuti kutyisidzika kwekutengesa kunowanzoshanda sei. Zvose zvakasiyana zvakasiyana asi pamwoyo yavo, pane dzimwe nguva kufanana kupfuura kusiyana. Uye tisati tadzokorora zvakanakisisa kushungurudzwa kushandiswa zvishandiso uye software, tinokurukura maitiro avo makuru.

Kutanga Kutambudzika

Makombiyuta matsuro uye masangano akawana hukuru hwekuoma kunzwisisa kupfuura kare. Nhasi muvharesi wevadiresi aigona kunge achishanda mazana emaitiro. Chimwe nechimwe chezvinhu izvi chirongwa chekombiyuta, mamwe acho mapurogiramu makuru anowanikwa nezviuru zvemitsara yemutsetse wekodha. Uye mukati memutsetse uyu, pangave-pane pangangove-yose yezvinhu zvisingatarisirwi. Imwe nyanzvi inogona, pane imwe nguva, yakawedzera chimwe chinhu chekunze kwemukati kuti kugadzirisa dambudziko kunyore. Uye gare gare, izvi zvingave zvisiri izvo zvakakonzera kushandurwa kwokupedzisira. Ikoko kunogonawo kunge kune dzimwe mhosho mumashoko ekugonesa achaita kuti zvisatarisirwe-uye zvisingadi-zvitsva mune imwe mamiriro ezvinhu chaiwo.

Zvose zveizvi zvinogona kushandiswa kuedza kuwana ruzivo rwemaitiro uye data. Pane boka guru revanhu vari kunze uko vasina chakanaka chekuita pane kuwana makomba aya uye kuvashandisa kuti varwise zvirongwa zvako. Zvinotambudza ndezvatinoti masango aya. Kana ikasara isina kuchengetedzwa, kusagadzikana kunogona kushandiswa nevashandisi vane utsinye kuti vawane maitiro ako uye data-kana zvichida zvakanyanya, data yevabereki vako-kana kuti zvingakonzera zvimwe zvinokuvadza zvakadai sokuita kuti masero ako asakwanise.

Zvinotambudza zvinogona kuva pose pose. Vanowanzowanika mumashandisirwo emapurogiramu emashandisi enyu kana maitiro avo ekushanda asi ivowo varipo mumashandisi ekubatanidza shanduko, shanduko, routers uye kunyange zvigadzirwa zvekuchengetedza zvakadai semoto. Mumwe unonyatsoda kuvatsvaga pose pose.

Kuongorora Zviratidzo - Ndezvipi Uye Vanoita Sei?

Kushungurudza kushandiswa-kana kuongorora-zvishandiso zvine basa guru rekutanga: kuratidza kusagadzikana mune zvirongwa zvako, zvigadzirwa, zvigadzirwa, uye software. Iko kunonzi ma scanners nokuti kazhinji vanowanzoongorora zvishandiso zvenyu kuti vatsvake kutadza kunzwisisika.

Asi matambudziko ekutsvaga matambudziko anowanikwa sei matambudziko anowanzo asiripo pachena? Kana ivo vakanga vari pachena, vashanduri vangadai vakataura navo vasati vasunungura software. Mutsa kana akaita sevharusi yakachengetedza software inoshandisa zvirwere zvekutsvaga zvinyorwa zvinyorwa zvekuona kombiyuta virusi zvinyorwa, kunyanya kunetseka zvipimo zvinotsigira kunetseka kwemasayenzi uye kuongorora zvirongwa zvekunetseka. Izvi zvinyorwa zvekunetseka zvinogona kuwanika kubva kune mazita anozivikanwa ezvokuchengetedza mabhizimisi ekuchengetedzwa kwemasimba akazvitsaurira kuwana kushaya simba mune software uye hardware kana vanogona kunge vane zvigadzirwa zvemabhuku kubva kune mutengesi wezvombo. Sezvaunotarisira, huwandu hwekuona iwe hunova hwakanaka sehwandu hwekutsvaga iyo iyo yako inoshandisa.

Kuverenga Zvirongwa - Ndiani Anozvida?

Mhinduro imwechete-kumubvunzo iwoyo yakajeka pachena: Munhu wese! Hapana munhu mupfungwa dzake dzakanaka angafunga nezvekutamba kombiyuta pasina hutachiona huchengetedzwa mazuva ano.

Kurwisa kungave kuri kuuya kubva kune imwe nzvimbo uye kukurova iwe kwaunenge usingatarisiri ivo. Iwe unofanirwa kuziva nezvenjodzi yako yekutsvaga.

Izvi zvinogona kunge chimwe chinhu chingave chinodaro chakaitwa nemaune. Kunyanya, zvakadaro, iri basa rinenge risingabviri. Kungova kuwana ruzivo pamusoro pekutadza, regai kuverenga nzira dzenyu dzekuvapo kwavo, zvingatora huwandu hwakawanda hwezvinhu. Mamwe masangano akazvitsaurira kuti awane dambudziko uye anowanzoshandisa mazana kana zvisati zvuru zvevanhu.

Munhu wose anotarisira mhando dzekombiyuta kana maikironi angabatsirwa zvikuru nekushandisa shanduko yekutsvaga shanje. Uyezve, kutevedzera mitemo yekutonga yakadai sa SOX kana PCI-DSS inowanzomira kuti iwe uite. Uye kunyange kana vasingazvidi, kutevera kunowanzova nyore kuratidza kana iwe unogona kuratidza kuti uri kuongorora network yako nekuda kwekunetseka.

Kushungurudzwa Kutungamirirwa muNutshell

Tsvaga kushaya simba kushandisa imwe shanduro yekushandisa inokosha. Ndiyo danho rokutanga mukudzivirira kurwisana. Asi iyo inofadza isina maturo kana isiri chikamu chekugadzirisa kwekugadzirisa kutadza. Kuongororwa Kuziva maitiro hausi intrusion Prevention Systems uye, nenzira imwecheteyo, Network masimba ekutsvaga zvidzidzo-kana kuti vazhinji vavo-vanoona chete kushaya simba uye vanokuchenesai nezvekuvapo kwavo.

Iko zvino kukwira kwauri, mutungamiri, kuti ave nedzimwe nzira panzvimbo yekutarisa kuonekwa kushaya simba. Chinhu chokutanga chavanofanira kuita pavanoona ndeyekuongorora kutadza. Iwe unoda kuve nechokwadi kuti unoona kushaya simba ndeyechokwadi. Kushungurudza kushandiswa kwezvombo zvinoshandiswa kusarudza kukanganisa kune rumwe rutivi rwekuchenjerera uye vazhinji vacharondedzera imwe nhamba yezvipo zvenhema. Uye kana nekunetseka kwechokwadi, vangave vasina hanya. Semuenzaniso, kushandiswa kusina kushandiswa kwePI pane sevhavha inogona kunge isingave yakakosha kana ichitsvaga kumashure kwechiedza chemasikati chinodzivirira chikwangwani ichocho.

Pane imwe nguva kushaya njodzi kunoongororwa, inguva yekugadzirisa nzira yekugadzirisa-uye kugadzirisa-iyo.

Iyo software inobatanidza neNational Vulnerability Database iyo inoita kuti ifananidzwe kuva pane zvinyorwa zvedu zvakare. Inosvika kune yeCVE yakanyanya kunyanya kuongorora kusagadzikana mune zvigadzirwa zveCisco. Ichishanda pamwe nemhando ipi neipi yeCisco inoshandisa ASA, IOS, kana Nexus OS. Zvechokwadi, mamwe mairi maviri anobatsira, Network Insights yeAAA uye Network Insights yeNexus yakavakirwa zvakanaka muchibereko.

Mitengo yeSolarWinds Network Configuration Manager inotanga pa $ 2,895 yepamusoro kune nhamba dze 50 dzakagadzikana uye dzinofanana maererano nhamba ye nodes. Kana iwe uchida kupa chiyi ichi edza, shanduro yekusangana yeC30-day inogona kutorwa kubva kuSolarWinds.

2. Microsoft Baseline Security Analyzer (MBSA)

Iyo Microsoft Baseline Security Analyzer, kana MBSA, chishandiso chakati kurei kubva kuMicrosoft. Kunyangwe iri shoma-pane-yakanaka sarudzo yemasangano makuru, chishandiso chinogona kuve chakaringana kumabhizinesi madiki, ayo ane mashoma maseva chete. Ichi chishandiso cheMicrosoft saka iwe zvirinani usatarisira t kuti utarise scan asi zvigadzirwa zveMicrosoft kana iwe unozonyadziswa Izvo, zvakadaro, ichaongorora iyo Windows inoshanda sisitimu pamwe nemamwe masevhisi senge Windows Firewall, SQL server, IIS uye Microsoft Office zvinoshandiswa.

Asi chigadziriro ichi hachirevi kuti chinetso chakangoita sevamwe matanho ekuchengetedza. Chinoita ndechokutsvaga mabheji akashayikwa, mapepa emabasa uye zvigadzidzo zvekuchengetedza pamwe nekuongorora zvirongwa zvemashoko ekutungamirira. Iyo MBSA yekubika injini ichakuita kuti iwe uwane runyora rwekushayikwa kwezvinhu zvisina kunaka uye kusagadziriswa.
