A system flaw comes from an incorrect assumption that another component can always be trusted. Which design weakness does this describe?
Answer
Implicit trust
Explanation
### Why this is right
Implicit trust is a design limitation in which a system assumes another component or party is trustworthy without sufficient checks. The material lists it among design-related vulnerability sources.
### The concept
Vulnerabilities can arise from design or implementation. Design issues include limitations, unforeseen conditions, and implicit trust. Implementation issues include coding errors and misconfigurations.
### The other options
- **A coding error**: an implementation mistake in program code.
- **A misconfiguration**: an implementation or setup error.
- **A denial of service**: an attack impact involving unavailability.
### Terms
- **Implicit trust**: an unstated assumption that another component or party is trustworthy.
- **Misconfiguration**: an incorrect system or software setting.
### Remember
Ask whether the problem is in the design assumption or in how the design was implemented.
