Muzera ranhasi redhijitari, kuchengetedza ruzivo rwakadzama uye data kubva kutyisidziro yecyber kwakakosha. Chimwe chishandiso chinoshanda munzvimbo yecybersecurity intrusion yekuona system (IDS). Iyi sisitimu inotarisisa network traffic uye inoona zvisina kutenderwa kana fungidziro zviitiko zvinogona kuratidza zvinogona kukanganisa kuchengetedza. Nekunzwisisa tsananguro uye chinangwa cheIDS, vanhu, uye masangano vanogona kutora matanho ekuchengetedza manetwork avo uye kudzivirira zvinogona kutyisidzira.
Mhando dzeIntrusion Detection Systems.
Maviri epakati pekupinda ekuona masisitimu aripo: network-based IDS (NIDS) uye host-based IDS (HIDS).
1. Network-based IDS (NIDS): Iyi mhando yeIDS inotarisisa network traffic uye inoongorora mapaketi edata kuona chero zviitiko zvinofungirwa kana zvisina mvumo. NIDS inogona kuona kurwiswa kwakasiyana, senge port scanning, kurambwa kwesevhisi (DoS) kurwiswa, uye kutapukira kwemalware. Inoshanda padanho retiweki uye inogona kuiswa zvine hungwaru mukati meiyo network network.
2. Host-based IDS (HIDS): Kusiyana neNIDS, HIDS inotarisa pakuongorora mabasa pane ega ega ega masisitimu kana magumo. Inoongorora matanda ehurongwa, kutendeseka kwefaira, uye maitiro emushandisi kuona zviratidzo zvekupindira kana kukanganisa. HIDS inogona kupa ruzivo rwakadzama nezvechaiwo mauto uye inonyanya kubatsira pakuona kutyisidzira kwemukati kana kurwiswa kunonangana nemamwe masisitimu.
Ose ari maviri NIDS neHIDS anoita mabasa akakosha mukuchengetedzwa kwetiweki, uye masangano mazhinji anosarudza kuendesa musanganiswa wezvose zviri zviviri kuti ave nechokwadi chekuchengetedzwa kwakazara kubva kunjodzi dzinogona kuitika.
Mashandiro anoita IDS.
Iyo intrusion monitoring system (IDS) inotarisisa network traffic kana zviitiko pamasisitimu ega ega kuti aone zviitiko zvisina mvumo kana fungidziro. Inoongorora mapaketi edatha, matanda ehurongwa, kutendeseka kwefaira, uye maitiro emushandisi.
Network-based IDS (NIDS) inoshanda padanho retiweki uye inogona kuiswa zvine hungwaru munzvimbo dzakasiyana siyana mukati meiyo network network. Inoongorora traffic yetiweki uye inotarisa mapatani kana masiginecha ekurwiswa kunozivikanwa, senge port scanning, kurambwa kwesevhisi (DoS) kurwiswa, kana kutapukirwa nemalware.
Kune rimwe divi, host-based IDS (HIDS) inotarisana nekutarisa zviitiko pane ega ega masisitimu kana magumo. Inotarisa chero zviratidzo zvekupindira kana kukanganisa nekuongorora matanda ehurongwa, kutendeseka kwefaira, uye maitiro emushandisi. HIDS inogona kupa ruzivo rwakadzama nezvechaiwo mauto uye inonyanya kubatsira pakuona kutyisidzira kwemukati kana kurwiswa kunonangana nemamwe masisitimu.
Ose ari maviri NIDS neHIDS anoita mabasa akakosha mukuchengetedzwa kwetiweki, uye masangano mazhinji anosarudza kuendesa musanganiswa wezvose zviri zviviri kuti ave nechokwadi chekuchengetedzwa kwakazara kubva kunjodzi dzinogona kuitika. Nekuenderera mberi nekutarisa network traffic uye zviitiko zvekugamuchira, IDS inogona kubatsira kuziva uye kupindura kune zvinogona kukanganisa kuchengetedza, zvichibvumira masangano kutora matanho akakodzera kuchengetedza network yavo uye data.
Zvakanakira Kuita IDS.
Kuita intrusion yekuona sisitimu (IDS) inogona kupa akati wandei mabhenefiti kumasangano ane chekuita netiweki chengetedzo.
Chekutanga, IDS inogona kubatsira kuona nekudzivirira kupinda kunetiweki kusina mvumo. IDS inogona kuona zvinogona kutyisidzira uye nekuzivisa maneja kuti atore matanho nekukasira nekutarisa network traffic uye kuongorora mapatani kana masiginecha ekurwiswa kunozivikanwa. Izvi zvinogona kubatsira kudzivirira kutyora kwedata, kuwana kusingatenderwe kune ruzivo rwakadzama, uye zvimwe zviitiko zvekuchengetedza.
