Hello, dear friends. We have now finished exploring the topic of Security. Now, we'll start answering some questions about this topic to help us learn more. Let's begin with the first question. Which of the following options is not part of the security features or security model of the Java SE environment? WS security, Web Start, JAAS, Applet. WS-Security is not part of the security features or security model of the Java SE environment. Other options are security features or parts of the security model of the Java SE environment. So, the correct answer is A. Now let's go to the second question. Which of the following options is possible for an unsigned Java application? None of these actions are allowed for an unsigned Java application. So, the correct answer is E. Let's go on to the next question. Which of the following is the mechanism that restricts all applications installed over a network from accessing security-sensitive resources, such as the local file system? Java SDK, IPSec, Sandbox, JAAS.

Other the mechanisms do not prevent applications from accessing security-sensitive resources. Select appropriate locations in the UML component and distribution table to apply Java EE security technologies or features. A Sandbox is responsible for controlling access to security-sensitive resources. So, the answer is C. Let's go to the next question. Which of the following options is not an available location for Java EE security features in a UML diagram? All of the other options are valid locations for Java EE security features in a UML diagram. The load balancer is not a valid location for Java EE security features in the UML schema. So, the correct answer is D.

Let's go on to the next question. Which of the following options is a valid security deployment identifier for a Java EE web component? Other options are not valid security deployment descriptors for a Java EE web component. login-schema is a valid security deployment identifier for a Java EE web component. So, the answer is B. Let's go on to the next question. Which of the following options will show as a valid security deployment descriptor for a Java EE enterprise bean component? Method-permission, ejb-home, identity, ejb-security. Now, method-permission is a valid security deployment identifier for a Java EE enterprise bean component. Other options are not valid security deployment descriptors for a Java EE enterprise bean component. So, the correct answer is A. Let's go on to the next question. Which of the following security technologies can be used in the message layer? Let's examine the options. Firewalls, all of the above, WS-Security, IPSec. WS-Security can be applied to the message layer.

Firewalls and IPSec do not apply to the message layer. Therefore, the correct answer is C. Let's go on to the last question of this topic. Which of the following security technologies can be used in the transport layer? Secure Sockets Layer, digital fingerprint, message digest, intercepting filter. Message digest, blocking filter, and digital fingerprint are not related to the transport layer. Secure Sockets Layer, or SSL, can be applied to the transport layer. So, the correct answer is A. We have now finished examining the topics. With the next video, we'll start to solve exam questions. We'll see you in the next video.
