How does SSL/TLS enhance web security?

• A. By storing user data in a central location
• B. By encrypting data exchanged between a web server and a client
• C. By automatically updating web applications
• D. By blocking all incoming traffic

Answer: (B)

SSL/TLS enhances web security primarily through the process of encrypting data exchanged between a web server and a client. This encryption ensures that the information transmitted over the internet remains confidential and protected from eavesdropping or tampering by unauthorized parties. By using SSL/TLS, sensitive data such as login credentials, personal information, and financial details can be securely shared, reducing the risk of data breaches and unauthorized access.

The use of SSL/TLS also provides authentication, which helps to ensure that clients are communicating with the legitimate web server they intended to contact, further establishing trust in the session. Additionally, it promotes data integrity, meaning that any alterations to the data during transmission can be detected, preventing unwanted modifications.

In contrast, options that suggest storing user data centrally, automatically updating web applications, or blocking incoming traffic do not capture the core function of SSL/TLS in securing communications between a client and server. These activities address different aspects of security and operational functionality but do not specifically denote the encryption and protection of data in transit that SSL/TLS provides.
