IPS (Intrusion Prevention System) Nedir?<\/h2>\n

Bir siber sald\u0131r\u0131 \u00f6nleme sistemi olan IPS (Intrusion Prevention System), tehlikeli, \u015f\u00fcpheli ve risk olu\u015fturabilecek aktiviteleri izleyerek engellenmesini sa\u011flar. IPS, s\u00fcrekli olarak a\u011f \u00fczerindeki trafi\u011fi takip eder ve kontrol eder. Normal d\u0131\u015f\u0131 bir durum belirledi\u011finde ise veri ak\u0131\u015f\u0131n\u0131 k\u0131s\u0131tlar ve a\u011f y\u00f6neticisine uyar\u0131 iletir.<\/span><\/p>\n

IPS (Intrusion Prevention System) Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/h2>\n

IPS sistemi genel olarak g\u00fcvenlik duvar\u0131n\u0131n arkas\u0131nda yer al\u0131r. K\u00f6t\u00fc ama\u00e7l\u0131 aktivitenin tespit edildi\u011fi durumlarda ba\u011flant\u0131y\u0131 s\u0131f\u0131rlamak, y\u00f6neticileri uyarmak ve kaynak adresten gelen trafi\u011fi engellemek gibi bir\u00e7ok otomatik eylemi ger\u00e7ekle\u015ftirir.\u00a0<\/span><\/p>\n

Ayr\u0131ca tehditleri belirlemek i\u00e7in kullan\u0131lan birka\u00e7 farkl\u0131 y\u00f6ntem bulunmaktad\u0131r:<\/span><\/p>\n

\u0130mza Tabanl\u0131: Tespit edilen tehditlerin anti-vir\u00fcs programlar\u0131 taraf\u0131ndan imza olarak ifade edilmesinden bu terminoloji ortaya \u00e7\u0131km\u0131\u015ft\u0131r. Bu yakla\u015f\u0131m daha \u00f6nce bilinen a\u011f tehditlerinin tekrar bir probleme yol a\u00e7mas\u0131n\u0131 engellemek i\u00e7in kullan\u0131l\u0131r.<\/span><\/p>\n

Anomali Tabanl\u0131: \u0130mza tabanl\u0131 izlemeye g\u00f6re daha g\u00fcvenilir olan anomali tabanl\u0131 y\u00f6ntemde, a\u011f \u00fczerindeki aktiviteleri temel standartlarla kar\u015f\u0131la\u015ft\u0131r\u0131r. Yapay zeka ve makine \u00f6\u011frenimi bu y\u00f6ntemi desteklemek i\u00e7in kullan\u0131l\u0131r.<\/span><\/p>\n

\u0130lke Tabanl\u0131: \u0130mza tabanl\u0131 veya anormal tabanl\u0131 y\u00f6nteme g\u00f6re daha az yayg\u0131nd\u0131r. Kurulu\u015f taraf\u0131ndan tan\u0131mlanan g\u00fcvenlik ilkelerini tehdit eden veya \u015f\u00fcpheli durum olu\u015fturan faaliyetler engellenir. Bunun i\u00e7in daha \u00f6nce g\u00fcvenlik ilkelerini belirlenip, yap\u0131land\u0131rmak gerekir.<\/span><\/p>\n

IPS (Intrusion Prevention System) T\u00fcrleri Nelerdir?<\/h2>\n

NBA (Network Behavior Analysis): DDoS sald\u0131r\u0131lar\u0131 gibi a\u011fda ger\u00e7ekle\u015ftirilen ola\u011fan d\u0131\u015f\u0131 trafik davran\u0131\u015f\u0131n\u0131 tespit etmek i\u00e7in kullan\u0131l\u0131r.<\/span><\/p>\n

HIPS (Host Based Intrusion Prevention): T\u00fcm a\u011f\u0131 kontrol etmez sadece kuruldu\u011fu bilgisayardaki trafi\u011fi kontrol eder.\u00a0<\/span><\/p>\n

NIPS (Network-Based Intrusion Prevention): Proaktif tarama yap\u0131lmas\u0131 i\u00e7in a\u011f trafi\u011findeki tehditleri izlemeye yard\u0131mc\u0131 olur.<\/span><\/p>\n

WIPS (Wireless Intrusion Prevention Systems): Wi-Fi a\u011f\u0131 \u00fczerindeki tehditleri izlemek ve yetkisiz eri\u015fimleri \u00f6nlemek i\u00e7in kullan\u0131l\u0131r.<\/span><\/p>\n

IDS (Intrusion Detection System) Nedir?<\/h2>\n

Bir a\u011f\u0131 s\u00fcrekli olarak izleyerek ve tarayarak g\u00fcvenlik a\u00e7\u0131klar\u0131, potansiyel sald\u0131r\u0131lar, \u015f\u00fcpheli aktiviteler gibi durumlara kar\u015f\u0131 kullan\u0131lan yaz\u0131l\u0131m ya da donan\u0131m g\u00fcvenlik sistemidir. IDS sistemi temel olarak meydana gelen sald\u0131r\u0131lar\u0131 tespit etmenin yan\u0131 s\u0131ra karantinaya almak, raporlamak, kaydetmek gibi farkl\u0131 i\u015flevleri de bulunmaktad\u0131r. Ayr\u0131ca IPS sistemi ile entegre bir \u015fekilde kullan\u0131labilir.<\/span><\/p>\n

IDS T\u00fcrleri Nelerdir?<\/h2>\n

Network Intrusion Detection System (NIDS): A\u011fdaki t\u00fcm cihazlardan gelen trafi\u011fi incelemek i\u00e7in a\u011f i\u00e7inde planl\u0131 bir noktada kurulur. Bir sald\u0131r\u0131 tespit edildi\u011finde veya anormal bir etkinlik g\u00f6zlemlendi\u011finde uyar\u0131 g\u00f6nderilebilir.<\/span><\/p>\n

Host Intrusion Detection System (HIDS): A\u011f \u00fczerinde bulunan ba\u011f\u0131ms\u0131z ana bilgisayarlar ya da ayg\u0131tlar \u00fczerinde \u00e7al\u0131\u015f\u0131r. Gelen ve giden trafi\u011fi izleyerek \u015f\u00fcpheli bir etkinlik alg\u0131land\u0131\u011f\u0131nda y\u00f6neticiyi uyar\u0131r.<\/span><\/p>\n

Protocol-based Intrusion Detection System (PIDS): Kullan\u0131c\u0131 ya da cihaz ile sunucu aras\u0131ndaki protokol\u00fc kontrol eder.<\/span><\/p>\n

\u00d6zetle, her iki sistem de g\u00fcvenlik duvar\u0131 arkas\u0131nda \u00e7al\u0131\u015fabilir. Ayr\u0131ca hem donan\u0131m hem de yaz\u0131l\u0131msal olarak faaliyet g\u00f6sterebilir. IDS kullan\u0131larak potansiyel sald\u0131r\u0131lar tespit etmek hedeflenir ve al\u0131nacak aksiyon raporlan\u0131r.\u00a0 IPS otomatik olarak aksiyona ge\u00e7ebilir. IPS kullan\u0131larak sald\u0131r\u0131lar\u0131 durdurmak ve \u00f6nlemek ama\u00e7lan\u0131r.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
