- Self-signed certificates trigger browser warnings despite being more secure than no certificate.
- Self-signed certificates prevent MITM attacks as effectively as CA-signed certificates when combined with certificate pinning.
- CA-signed certificates rely on trust in certificate authorities, which can be compromised, affecting all websites.
- Pinning self-signed certificates limits MITM opportunities to the first connection, unlike CA-signed certificates which have broader vulnerabilities.
- Real-world examples like Opera and Nokia show CA vulnerabilities leading to MITM attacks.
