**Understanding HTTPS: Protecting Your Online Data** **Overview of HTTPS Protection:** HTTPS (HyperText Transfer Protocol Secure) is a protocol used to secure data transmitted over the internet. It is critical in safeguarding users against various online threats, ensuring that information shared between a user's browser and a website is encrypted and safe from eavesdroppers. **Risks Mitigated by HTTPS:** 1. **Data Interception:** - HTTPS prevents unauthorized interception by encrypting data during transmission. This means sensitive information like passwords and credit card details are kept secure from hackers. 2. **Data Tampering:** - It protects against data tampering, ensuring that the data exchanged has not been altered by third parties during the transmission. 3. **Man-in-the-Middle Attacks (MITM):** - HTTPS helps prevent MITM attacks, where an attacker intercepts communication between two parties. The use of encryption and certificates verifies the authenticity of the web server. 4. **Phishing:** - HTTPS provides visual cues, like a padlock icon, in the address bar that help users identify legitimate websites, reducing the risk of phishing scams. **Techniques Employed by HTTPS:** 1. **Encryption:** - Uses protocols such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to encrypt the data, making it unreadable to anyone who intercepts it. 2. **Certificates:** - Websites present digital certificates issued by Certificate Authorities (CAs) to prove authenticity. Browsers verify these certificates to establish a secure connection. 3. **Data Integrity:** - Utilizes hashing to ensure that the data sent and received is complete and not tampered with during transmission. Understanding and implementing HTTPS is essential for maintaining a secure and trustworthy internet environment, protecting both users and websites from potential cyber threats.
