Secure Web Practices (HTTPS, TLS)
Secure Web Practices involve using protocols like HTTPS and TLS to protect data exchanged between users and websites. HTTPS (Hypertext Transfer Protocol Secure) encrypts information, ensuring privacy and integrity during transmission. TLS (Transport Layer Security) is the underlying technology that secures connections, preventing eavesdropping, tampering, and forgery. These practices help build trust, safeguard sensitive information such as passwords and credit card details, and defend against cyber threats like man-in-the-middle attacks.

💡 Key Takeaways
- Understand that HTTPS and TLS encrypt data in transit to protect privacy and integrity.
- Identify secure websites by the HTTPS prefix and the padlock icon in the address bar.
- Know that TLS provides encryption, authentication, and checks that data hasn't been tampered with during a web connection.
- Practice safe web habits, such as entering sensitive information only on HTTPS sites and keeping your browser up to date.
❓ Frequently Asked Questions
What is HTTPS and how does it differ from HTTP?
HTTPS stands for Hypertext Transfer Protocol Secure. It adds encryption via TLS/SSL to HTTP, protecting data in transit and authenticating the server; HTTP transmits data in plaintext.
What is TLS and what role does it play in web security?
TLS (Transport Layer Security) is the protocol that provides encryption, authentication, and data integrity for data in transit. HTTPS uses TLS to secure web traffic.
How can you tell if a website is using HTTPS securely?
Check that the URL starts with https://, look for a padlock icon in the address bar, and view the site's certificate details to ensure it’s valid and issued by a trusted authority.
What is a TLS certificate and why is it needed?
A TLS certificate proves a site’s identity and enables encryption by sharing the site's public key with the browser. It is issued by a trusted Certificate Authority and helps establish a secure connection.
