D487: Secure Software Design
Questions and Answers
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.
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.
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?
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?
Iterative model
Waterfall model
V-model
, Agile model
Agile model
In the agile model, projects are divided into small incremental builds that provide working software at
the end of each iteration and adds value to business.
In Scrum methodology, who is responsible for making decisions on the requirements?
Scrum Team
Product Owner
ScrumMaster
Technical Lead
Product Owner
The Product Owner is responsible for requirements/backlog items and prioritizing them.
What is the reason software security teams host discovery meetings with stakeholders early in the
development life cycle?
To determine how much budget is available for new security tools
To meet the development team
To refactor functional requirements to ensure security is included
To ensure that security is built into the product from the start
To ensure that security is built into the product from the start
To correctly and cost-effectively introduce security into the software development life cycle, it needs to
be done early.
