SSL, bir web sitesi ile kullan\u0131c\u0131 aras\u0131ndaki ileti\u015fimin \u015fifrelenmesini sa\u011flayan bir g\u00fcvenlik protokol\u00fcd\u00fcr.

G\u00fcvenlik Duvar\u0131 (Firewall) Nedir ve Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/strong><\/h4>\n

G\u00fcvenlik duvar\u0131, a\u011f trafi\u011fini izleyen ve istenmeyen eri\u015fimleri engelleyen bir g\u00fcvenlik \u00f6nlemidir. Bu, a\u011fa yetkisiz eri\u015fimi engelleyerek, k\u00f6t\u00fc ama\u00e7l\u0131 yaz\u0131l\u0131mlar\u0131n ve sald\u0131r\u0131lar\u0131n a\u011fa zarar vermesini \u00f6nler. G\u00fcvenlik duvar\u0131, a\u011f \u00fczerindeki trafi\u011fi denetler ve belirli kurallara uygun olmayan trafi\u011fi engeller.<\/p>\n

G\u00fcvenlik duvar\u0131, gelen ve giden trafi\u011fi analiz ederek, a\u011fa giri\u015f ve \u00e7\u0131k\u0131\u015flar\u0131 kontrol alt\u0131nda tutar. Bu, bilgisayar korsanlar\u0131n\u0131n veya k\u00f6t\u00fc niyetli yaz\u0131l\u0131mlar\u0131n a\u011fa s\u0131zmas\u0131n\u0131 \u00f6nlerken, a\u011fdaki verilerin g\u00fcvenli\u011fini sa\u011flar.<\/p>\n

SSL ve G\u00fcvenlik Duvar\u0131 Aras\u0131ndaki Etkile\u015fim<\/strong><\/h4>\n

SSL ve g\u00fcvenlik duvar\u0131, \u00e7evrimi\u00e7i g\u00fcvenli\u011fi art\u0131rmak i\u00e7in birlikte \u00e7al\u0131\u015f\u0131r. SSL, veri aktar\u0131m\u0131n\u0131 \u015fifreler ve bu sayede bilgi g\u00fcvenli\u011fini sa\u011flar. Ancak, bu veriler g\u00fcvenli bir \u015fekilde sunucuya ula\u015ft\u0131ktan sonra bile, sunucudaki k\u00f6t\u00fc ama\u00e7l\u0131 yaz\u0131l\u0131mlar veya sald\u0131r\u0131lar, verilere zarar verebilir.<\/p>\n

\u0130\u015fte bu noktada, g\u00fcvenlik duvar\u0131 devreye girer. G\u00fcvenlik duvar\u0131, a\u011f trafi\u011fini izleyerek, zararl\u0131 trafi\u011fi engeller ve a\u011fa s\u0131zmalar\u0131 \u00f6nler. B\u00f6ylece, SSL ile korunan verilerin, sunucuya ula\u015ft\u0131ktan sonra bile g\u00fcvenli kalmas\u0131n\u0131 sa\u011flar.<\/p>\n

\u00d6rne\u011fin, bir sald\u0131rgan, SSL ile korunan bir web sitesine zararl\u0131 bir yaz\u0131l\u0131m y\u00fckleyebilir veya sunucuya zararl\u0131 bir kod enjekte edebilir. Ancak, g\u00fcvenlik duvar\u0131 bu t\u00fcr sald\u0131r\u0131lar\u0131 alg\u0131lar ve engeller, b\u00f6ylece sunucunun g\u00fcvenli\u011fini sa\u011flar.<\/p>\n

G\u00fcvenlik duvar\u0131 ayr\u0131ca, a\u011f \u00fczerindeki trafi\u011fi denetleyerek, izinsiz eri\u015fim giri\u015fimlerini tespit eder ve engeller. \u00d6rne\u011fin, bir sald\u0131rgan\u0131n a\u011fa giri\u015f yapmaya \u00e7al\u0131\u015ft\u0131\u011f\u0131 tespit edilirse, g\u00fcvenlik duvar\u0131 bu giri\u015fimi engeller ve a\u011f\u0131n b\u00fct\u00fcnl\u00fc\u011f\u00fcn\u00fc korur.<\/p>\n

SSL ve g\u00fcvenlik duvar\u0131, \u00e7evrimi\u00e7i g\u00fcvenli\u011fi art\u0131rmak i\u00e7in birbirini tamamlayan \u00f6nlemlerdir. SSL, veri aktar\u0131m\u0131n\u0131 \u015fifreleyerek bilgi g\u00fcvenli\u011fini sa\u011flarken, g\u00fcvenlik duvar\u0131 a\u011f trafi\u011fini izleyerek zararl\u0131 sald\u0131r\u0131lar\u0131 engeller. Birlikte kullan\u0131ld\u0131klar\u0131nda, SSL<\/a> ve g\u00fcvenlik duvar\u0131, \u00e7evrimi\u00e7i g\u00fcvenli\u011fi maksimum seviyeye \u00e7\u0131kar\u0131r ve kullan\u0131c\u0131lar\u0131n bilgilerini korur.<\/p>\n

Bu nedenle, hem SSL<\/strong> hem de g\u00fcvenlik duvar\u0131<\/strong>, modern bir internet kullan\u0131m\u0131nda vazge\u00e7ilmez \u00f6nlemlerdir ve her t\u00fcr web sitesi ve a\u011f i\u00e7in b\u00fcy\u00fck \u00f6nem ta\u015f\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
