What are the two common best principles of software applications in the
development process? Choose 2 answers.
Quality code
Secure code
Information security
Integrity
Availability
Quality code
Secure code
"Quality code" is correct. Quality code is efficient code that is easy to maintain and
reusable.
"Secure code" is correct. Secure code authorizes and authenticates every user
transaction, logs the transaction, and denies all unauthorized requisitions.
,WGU D487 SECURE SOFTWARE DESIGN
What ensures that the user has the appropriate role and privilege to view data?
Authentication
Multi-factor authentication
Encryption
Information security
Authorization
Authorization
Authorization ensures a user's information and credentials are approved by the
system.
Which security goal is defined by "guarding against improper information
modification or destruction and ensuring information non-repudiation and
authenticity"?
Integrity
Quality
Availability
Reliability
Integrity
The data must remain unchanged by unauthorized users and remain reliable from
the data entry point to the database and back.
,WGU D487 SECURE SOFTWARE DESIGN
Which phase in an SDLC helps to define the problem and scope of any existing
systems and determine the objectives of new systems?
Requirements
Design
Planning
Testing
Planning
The planning stage sets the project schedule and looks at the big picture.
What happens during a dynamic code review?
Programmers monitor system memory, functional behavior, response times, and
overall performance.
Customers perform tests to check software meets requirements.
An analysis of computer programs without executing them is performed.
Input fields are supplied with unexpected input and tested.
Programmers monitor system memory, functional behavior, response times, and
overall performance.
How should you store your application user credentials in your application
database?
, WGU D487 SECURE SOFTWARE DESIGN
Use application logic to encrypt credentials
Store credentials as clear text
Store credentials using Base 64 encoded
Store credentials using salted hashes
Store credentials using salted hashes
Hashing is a one-way process that converts a password to ciphertext using hash
algorithms. Password salting adds random characters before or after a password
prior to hashing to obfuscate the actual password.
Which software methodology resembles an assembly-line approach?
V-model
Agile model
Iterative model
Waterfall model
Waterfall model
Waterfall model is a continuous software development model in which the
development steps flow steadily downwards.
Which software methodology approach provides faster time to market and higher
business value?
