WGU C706 Secure Software Design Exam Guide Questions & Verified Answers 2024

Confidentiality - ✅✅Information is not made available or disclosed to unauthorized individuals, entities, or processes. Ensures unauthorized persons are not able to read private and sensitive data. It is achieved through cryptography. 1. Integrity -✅✅Ensures unauthorized persons or channels are not able to modify the data. It is accomplished through the use of a message digest or digital signatures. 2. Availability -✅✅The computing systems used to store and process information, the security controls used to protect information, and the communication channels used to access information must be functioning correctly. Ensures system remains operational even in the event of a failure or an attack. It is achieved by providing redundancy or fault tolerance for a failure of a system and its components. 3. Ensure Confidentiality -✅✅Public Key Infrastructure (PKI) and Cryptography/Encryption 4. Ensure Availability -✅✅Offsite back-up and Redundancy 5. Ensure Integrity -✅✅Hashing, Message Digest (MD5), non repudiation and digital signatures 6. Software Architect -✅✅Moves analysisto implementation and analyzes the requirements and use cases as activitiesto perform as part of the development process; can also develop class diagrams. 7. Security Practitioner Roles -✅✅Release Manager, 8. Architect, Developer, Business Analyst/Project Manager P a g e 1 | 19 9. Release Manager -✅✅Deployment 10. Architect -✅✅Design 11. Developer -✅✅Coding 12. Business Analyst/Project Manager -✅✅Requirements Gathering 13. Red Team -✅✅Teams of people familiar with the infrastructure of the company and the languages of the software being developed. Their mission isto kill the system as the developers build it. 14. Static Analysis -✅✅A method of computer program debugging that is done by examining the code without executing the program. The process provides an understanding of the code structure, and can help to ensure that the code adheres to industry standards. It's also referred as code review. 15. MD5 Hash -✅✅A widely used hash function producing a 128-bit hash value. Initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. 16. SHA-256 (Secure Hash Algorithm) - ✅✅One of a number of cryptographic hash functions. A cryptographic hash islike a signature for a text or a data file. Generates an almost-unique, fixed size 32-byte 17. (32 X 8) hash. Hash is a one-way function - it cannot be decrypted. 18. Advanced Encryption Standard (AES) -✅✅A symmetric encryption algorithm. The algorithm was developed by two Belgian cryptographers Joan Daemen and Vincent P a g e 2 | 19 WGU C706 Secure Software Design Study Guide Questions and Answers Latest Updated 2024.Great success Assured Rijmen. Designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits. 19. Algorithms used to verify integrity -✅✅MD5 Hash, SHA-256 20. Algorithm used to verify confidentiality -✅✅Advanced Encryption Standard (AES) 21. Stochastic -✅✅unintentional or accidental 22. safety-relevant faults-✅✅stochastic (i.e., unintentional or accidental) 23. security-relevant faults-✅✅"Sponsored," i.e., intentionally created and activated through conscious and intentional human agency. 24. Fuzz Testing -✅✅Used to see if the system hassolid exception handling to the input it receives. Is the use of malformed or random input into a system in order to intentionally produce failure. This is a very easy process of feeding garbage to the system when it expects a formatted input, and it is always a good idea to feed as much garbage as possible to an input field. 25. Three (3) Tier -✅✅Removes the business logic from the client end of the system. It generally placesthe business logic on a separate server from the client. The data access portion of the system resides separately from both the client and the business logic platform. 26. T-MAP -✅✅Defines a set of threat-relevant attributesfor each layer or node. These can be classified as probability-relevant, size-of-loss relevant, or descriptive. These are primarily derived from Common Vulnerability Scoring System (CVSS). USC's Threat Modeling based on Attacking Path analysis is a risk management approach that
