User data constraint is a security constraint element summarized in the Java Servlet Specification 2.4. It sets up a requirement to receive the

constrained requests over a protected layer connection, such as TLS (Transport Layer Security). The user data constraint offers guarantee

(NONE, INTEGRAL, and CONFEDENTIAL) for the transportation of data between client and server. If a request does not have user data

constraint, the container accepts the request after it is received on a connection.

Answer C is incorrect. Web resource collection is a set of URL patterns and HTTP operations that define all resources required to be

protected. It is a security constraint element summarized in the Java Servlet Specification v2.4. The Web resource collection includes the

following elements:

URL patterns

HTTP methods

Answer B is incorrect. Authorization constraint is a security constraint element summarized in the Java Servlet Specification 2.4. It sets

up a requirement for authentication and names the authorization roles that can access the URL patterns and HTTP methods as defined by the

security constraint. In the absence of a security constraint, the container accepts the request without requiring any user authentication. If no

authorization role is specified in the authorization constraint, the container cannot access constrained requests. The wildcard character '*'

specifies all authorization role names that are defined in the deployment descriptor.

Answer D is incorrect. It is not a security constraint element.

Microsoft software security expert Michael Howard defines the following heuristics for determining code review in 'A Process for Performing

Security Code Reviews':

Old code: Newer code provides better understanding of software security and has lesser number of vulnerabilities. Older code must be

checked deeply.

Code that runs by default: It must have high quality, and must be checked deeply than code that does not execute by default. Code

that runs by default increases the application's attack surface.

Code that runs in elevated context: It must have higher quality. Code that runs in elevated privileges must be checked deeply and

increases the application's attack surface.

Anonymously accessible code: It must be checked deeply than code that only authorized users and administrators can access, and it

increases the application's attack surface.

Code listening on a globally accessible network interface: It must be checked deeply for security vulnerabilities and increases the

application's attack surface.

Code written in C/C++/assembly language: It is prone to security vulnerabilities, for example, buffer overruns.

Code with a history of security vulnerabilities: It includes additional vulnerabilities except concerted efforts that are required for

removing them.

Code that handles sensitive data: It must be checked deeply to ensure that data is protected from unintentional disclosure.

Complex code: It includes undiscovered errors because it is more difficult to analyze complex code manually and programmatically.

Code that changes frequently: It has more security vulnerabilities than code that does not change frequently.

Software:

1.Security requirements derivation/elicitation and specification

2.Security risk assessment

3.Secure architecture and design

4.Secure implementation

5.Security testing

6.Security assurance

The following concepts represent the three fundamental principles of information security:

1.Confidentiality

2.Integrity

3.Availability

Answer B is incorrect. Privacy, authentication, accountability, authorization and identification are also concepts related to information

security, but they do not represent the fundamental principles of information security.
