Web g\u00fcvenli\u011fi, dijital d\u00fcnyada varl\u0131k g\u00f6steren her kurum ve birey i\u00e7in hayati bir \u00f6neme sahiptir. Kullan\u0131c\u0131lar ve web siteleri aras\u0131ndaki veri al\u0131\u015fveri\u015fini korumak, siber sald\u0131rganlar\u0131n en temel hedeflerinden biridir. Bu sald\u0131r\u0131lar\u0131n en sinsi ve tespiti zor olan t\u00fcrlerinden biri “Downgrade” (S\u00fcr\u00fcm D\u00fc\u015f\u00fcrme) sald\u0131r\u0131lar\u0131d\u0131r.

Neyse ki, HSTS (HTTP Strict Transport Security) gibi modern g\u00fcvenlik politikalar\u0131, bu t\u00fcr tehditlere kar\u015f\u0131 g\u00fc\u00e7l\u00fc bir savunma mekanizmas\u0131 sunar.
