TLS nedir?<\/h2>\n

TLS, Transport Layer Security ifadesinin k\u0131saltmas\u0131d\u0131r. \u0130nternet \u00fczerindeki iki sistem aras\u0131ndaki ileti\u015fimin \u015fifrelenmesine yard\u0131mc\u0131 olan g\u00fcvenlik protokol\u00fcd\u00fcr.<\/p>\n

E-posta sistemlerinde TLS hem kullan\u0131c\u0131 cihaz\u0131n\u0131n posta sunucusuna ba\u011flanmas\u0131nda hem de farkl\u0131 posta sunucular\u0131n\u0131n birbirleriyle ileti\u015fiminde kullan\u0131labilir.<\/p>\n

G\u00f6nderim s\u0131ras\u0131nda veriyi korur<\/h2>\n

TLS kullan\u0131lan bir ba\u011flant\u0131da mesaj verileri a\u011f \u00fczerinde a\u00e7\u0131k bi\u00e7imde iletilmek yerine \u015fifreli bir ileti\u015fim kanal\u0131 \u00fczerinden ta\u015f\u0131n\u0131r. Bu durum verinin aktar\u0131m s\u0131ras\u0131nda \u00fc\u00e7\u00fcnc\u00fc ki\u015filer taraf\u0131ndan okunmas\u0131 riskini azalt\u0131r.<\/p>\n

SMTP \u00fczerinde STARTTLS<\/h2>\n

Posta sunucular\u0131 SMTP ba\u011flant\u0131s\u0131 ba\u015flad\u0131ktan sonra STARTTLS komutu ile \u015fifreli ileti\u015fime ge\u00e7ebilir. Kar\u015f\u0131 sunucunun TLS desteklemesi g\u00fcvenli aktar\u0131m a\u00e7\u0131s\u0131ndan \u00f6nemlidir.<\/p>\n

IMAP ve kullan\u0131c\u0131 ba\u011flant\u0131lar\u0131<\/h2>\n

Kullan\u0131c\u0131lar\u0131n posta kutular\u0131na ba\u011fland\u0131\u011f\u0131 IMAP hizmetlerinde de TLS kullan\u0131l\u0131r. G\u00fcvenli IMAP ba\u011flant\u0131lar\u0131 \u00e7o\u011funlukla 993 numaral\u0131 port \u00fczerinden sa\u011flan\u0131r.<\/p>\n

TLS her \u015feyi \u00e7\u00f6zmez<\/h2>\n

TLS mesaj\u0131n aktar\u0131m kanal\u0131n\u0131 korur ancak zararl\u0131 i\u00e7erik, phishing veya hesap ele ge\u00e7irilmesi gibi t\u00fcm e-posta tehditlerini ortadan kald\u0131rmaz. G\u00fcvenli e-posta i\u00e7in TLS’in yan\u0131 s\u0131ra g\u00fc\u00e7l\u00fc parola, spam filtreleme ve g\u00f6nderen do\u011frulama teknolojileri de gereklidir.<\/p>\n

Modern kurumsal e-posta altyap\u0131s\u0131<\/h2>\n

\u0130\u015fletmeler kulland\u0131klar\u0131 e-posta hizmetinin g\u00fcncel TLS protokollerini ve ge\u00e7erli sertifikalar\u0131 destekledi\u011finden emin olmal\u0131d\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
