Assessing Corporate Cybersecurityintermediate
A company has perimeter controls and endpoint protections but does not protect data when employees transfer or use it. Identify the architectural gap and explain why the existing measures do not fully address it.
Answer
The gap is data security. Perimeter security helps protect systems from remote malicious activity, while endpoint security protects connected devices. Neither definition ensures that information is protected in every state. Data security is needed to protect information at rest, in motion, and in use.
Explanation
### What a good answer covers
- Identify data security as the missing architecture layer.
- Explain that perimeter measures focus on boundary and remote-access risks.
- Explain that endpoint controls focus on devices.
- State that data security protects information in storage, transfer, and use.
### The concept
Security architecture should be assessed by protection target, not by counting products. A company can have controls at its perimeter and on employee devices while leaving information exposed as it moves between systems or is processed. Data security addresses information regardless of its state, so it complements rather than replaces endpoint and perimeter measures.
### Terms
- **Data in motion**: information being transferred between locations or systems.
- **Data in use**: information being actively processed or accessed.
### Remember
Controls on boundaries and devices do not automatically protect information throughout its lifecycle.
