Question 1 of 30
In a scenario where a financial institution is implementing web services to handle sensitive customer transactions, they decide to use WS-Security for message protection. They configure the services to use UsernameTokens for authentication. However, they are concerned about potential security vulnerabilities. What additional measures should they consider to enhance the security of their web services beyond just using UsernameTokens?
Implement message encryption and digital signatures to protect the integrity and confidentiality of the messages.
Rely solely on SSL/TLS for securing the transport layer without additional message-level security measures.
Use only IP whitelisting to restrict access to the web services from known IP addresses.
Configure the services to log all authentication attempts without implementing any access control mechanisms.
