Web Services Security Recommendations

D.

As a network administrator, if you need to secure web services of your company to have secure transactions, the most suitable solution is to use Secure Sockets Layer (SSL).

SSL is a security protocol that provides secure communication over the internet. It ensures secure transactions by establishing an encrypted link between the web server and the client's browser. This encryption makes it difficult for any unauthorized person to intercept or read the data being transmitted.

SSL is widely used for secure transactions such as online banking, e-commerce, and other financial transactions. It is also used for secure communication between email servers and for securing remote access to networks.

HTTP is not a suitable solution for providing security as it is not a secure protocol. HTTP stands for Hypertext Transfer Protocol and is used for transmitting data over the internet. However, it does not provide any encryption, making it easy for hackers to intercept the data being transmitted.

VPN (Virtual Private Network) is a secure way of accessing resources over the internet. However, it is not specifically designed for securing web services, and using it to secure web services can be complicated and require additional configuration.

SMIME (Secure/Multipurpose Internet Mail Extensions) is a security protocol that provides end-to-end email security. It is not specifically designed for securing web services and is not widely used for securing web transactions.

In summary, for securing web services of your company, the recommended solution is to use SSL. It is a widely accepted and proven solution that provides encryption and security for online transactions.
