Häufige Web-Sicherheitslücken verstehen und beheben, die von VitaPulse erkannt werden

Hoch
Weak TLS Protocol (TLS 1.0 / 1.1)

Your server supports outdated TLS versions (1.0 or 1.1) that have known cryptographic weaknesses.

Risiko

TLS 1.0 and 1.1 are vulnerable to attacks like BEAST, POODLE, and CRIME. Attackers on the same network can exploit these weaknesses to decrypt traffic, steal session cookies, credentials, and personal data. Major browsers have deprecated these versions and may display security warnings to your users.

Lösung

Disable TLS 1.0 and 1.1 on your server and enforce TLS 1.2 or 1.3. Update your server configuration (Apache, Nginx, IIS) to only accept modern protocols. Test with SSL Labs after changes.

Beispiel
# Nginx ssl_protocols TLSv1.2 TLSv1.3;
