Peki g\u00fcvenlik duvar\u0131 nedir ?<\/span><\/p>\n

WAF (Web Application Firewall) Nedir?<\/span><\/h2>\n

Yukar\u0131da bahsetti\u011fimiz g\u00fcvenlik duvar\u0131n\u0131n terimsel kar\u015f\u0131l\u0131\u011f\u0131 WAF\u2019t\u0131r. WAF \u201c Web Application Firewall\u201d kelimelerinin ba\u015f harflerinden olu\u015fmaktad\u0131r. T\u00fcrk\u00e7e kar\u015f\u0131l\u0131\u011f\u0131 ise \u201cWeb Uygulamas\u0131 G\u00fcvenlik Duvar\u0131\u201dd\u0131r.<\/span><\/p>\n

Bu sanal duvar web sitesinde iletilen ve gelen t\u00fcm verileri incelemek ve filtrelemek ile g\u00f6revlidir.\u00a0 E\u011fer g\u00fcvenli\u011fi tehdit eden bir veri ile kar\u015f\u0131la\u015f\u0131rsa\u00a0 direkt olarak engeller ve sistemi korur. Yaln\u0131zca tek bir yerde bulunmayan bu WAF web uygulamas\u0131n\u0131n katmanlar\u0131nda bulunur ve gizlice girmeye \u00e7al\u0131\u015fan tehditlerin de i\u00e7eri giri\u015fine m\u00fcdahale eder.<\/span><\/p>\n

WAF (Web Application Firewall) Ne \u0130\u015fe Yarar?<\/span><\/h2>\n

WAF\u2019\u0131n g\u00f6revi ve \u00e7al\u0131\u015fma \u015fekli olduk\u00e7a basittir.\u00a0 WAF\u2019\u0131 daha iyi anlayabilmeniz i\u00e7in duvar \u00f6rne\u011fini verebiliriz. Bu duvar web uygulaman\u0131z\u0131 \u00e7evreler ve giri\u015fler yaln\u0131zca kontroll\u00fc bir \u015fekilde ger\u00e7ekle\u015fir. Web sitenize girmek isteyen zararl\u0131 her t\u00fcrl\u00fc veri daha i\u00e7eri girmeden engellenir ve siteniz korunmu\u015f olur.<\/span><\/p>\n

Diyelim ki bir web sitesi sahibisiniz ve sitenizin trafi\u011fi artarken g\u00fcvenli\u011fi de sa\u011flamak istiyorsunuz. WAF ile g\u00fcvenlik endi\u015fesi olmadan i\u00e7iniz rahat bir \u015fekilde web sitenizi kullanabilirsiniz. \u00d6rne\u011fin bir kullan\u0131c\u0131s\u0131 web sitenize eri\u015fmek i\u00e7in istek g\u00f6nderdi. Bu istek siz fark etmeden sunucuya gelir ve sunucu bu iste\u011fi alg\u0131lar. WAF koruma duvar\u0131 ile istek daha sunucunuza ula\u015fmadan kontrol edilir ve zararl\u0131 ise engellenir.<\/span><\/p>\n

WAF (Web Application Firewall) T\u00fcrleri Nelerdir?<\/span><\/h2>\n

WAF\u00a0 t\u00fcrleri kendi aras\u0131nda\u00a0 \u00fc\u00e7e ayr\u0131lmaktad\u0131r.<\/span><\/p>\n

1)\u00a0 \u00a0 \u00a0 A\u011f Tabanl\u0131 WAF<\/span><\/p>\n

A\u011f tabanl\u0131 WAF donan\u0131m tabanl\u0131 bir\u00a0 koruma duvar\u0131d\u0131r.\u00a0 Cihaza yak\u0131n bir yerde bulunarak koruma ger\u00e7ekle\u015ftirilir. \u00d6rne\u011fin ofisinizde veya evinizde yak\u0131n bir \u015fekilde konumland\u0131r\u0131lmas\u0131 gerekmektedir. \u00d6zellikle\u00a0 birden fazla cihazda kural ve ayarlar\u0131n kopyalanabilmesi m\u00fcmk\u00fcn oldu\u011fu i\u00e7in s\u0131kl\u0131kla tercih edilmektedir. A\u011f tabanl\u0131 WAF\u2019\u0131n g\u00f6z\u00a0 ard\u0131 edilmemesi gereken bir dezavantaj\u0131 da maliyetidir.\u00a0 Di\u011fer t\u00fcrlerine g\u00f6re daha pahal\u0131 ve bak\u0131m\u00a0 gerektiren bir koruma duvar\u0131d\u0131r.<\/span><\/p>\n

2)\u00a0 \u00a0 \u00a0 Ana Bilgisayar Tabanl\u0131 WAF<\/span><\/p>\n

WAF bu t\u00fcrde ana sunucuya ba\u011fl\u0131d\u0131r. Bu sebeple y\u00f6netilmesinde zorluklar ya\u015fanabilir. Maliyet a\u00e7\u0131s\u0131ndan bak\u0131ld\u0131\u011f\u0131nda a\u011f tabanl\u0131 WAF gibi bak\u0131m maliyeti \u00e7ok olmamas\u0131na ra\u011fmen kullan\u0131m\u0131 zor oldu\u011fu i\u00e7in fazla personele ihtiya\u00e7 duyulmaktad\u0131r.<\/span><\/p>\n

3)\u00a0 \u00a0 \u00a0 Bulut\u00a0 Tabanl\u0131 WAF<\/span><\/p>\n

Olduk\u00e7a kolay kurulumu ve maliyeti d\u00fc\u015f\u00fck olmas\u0131 sebebiyle en \u00e7ok tercih edilen WAF t\u00fcr\u00fcd\u00fcr. Bu t\u00fcr\u00fc kullanmak i\u00e7in DNS veya Proxy de\u011fi\u015fikli\u011fine ihtiya\u00e7 duyulmaktad\u0131r.<\/span><\/p>\n

WAF Kullanman\u0131n Avantajlar\u0131 Nelerdir?<\/span><\/h2>\n

G\u00fcn\u00fcm\u00fczde bir \u00e7ok bilgisayar korsan\u0131 bulunmakta ve web sitelerine zarar vermeye \u00e7al\u0131\u015fmaktad\u0131r.\u00a0 Siber sald\u0131r\u0131 ad\u0131 verilen bu zararlardan korunma y\u00f6ntemlerinin ba\u015f\u0131nda WAF gelmektedir.\u00a0 Sisteminizin i\u00e7erisine girmeden e\u015f zamanl\u0131 bir g\u00fcvenlik duvar\u0131na sahip olmak i\u00e7in siz de Waf kullanabilirsiniz.<\/span><\/p>\n

WAF yaln\u0131zca web sitenizi de\u011fil m\u00fc\u015fterilerinizi de koruma garantisi sunmaktad\u0131r. M\u00fc\u015fteriler sitenizden al\u0131\u015fveri\u015f yapt\u0131\u011f\u0131nda pek \u00e7ok ki\u015fisel bilgiyi sizlerle payla\u015f\u0131r ve bir nevi size g\u00fcvenir. E\u011fer gerekli bir g\u00fcvenlik sistemine sahip olmazsan\u0131z bu bilgilerin k\u00f6t\u00fc ama\u00e7l\u0131 ki\u015filerin eline ge\u00e7mesi olduk\u00e7a kolayd\u0131r.

K\u0131saca \u00f6zetlemek gerekirse WAF sizin ve m\u00fc\u015fterilerinizin g\u00fcvenli\u011fi i\u00e7in gerek duyulan b\u00fct\u00fcn korumay\u0131 sa\u011flamaktad\u0131r.
