Which of the following is MOST likely to result from a poorly enforced bring your own device (8YOD) policy?
- A. Shadow IT
- B. Weak passwords
- C. Unapproved social media posts
- D. Network congestion
Answer: A
Explanation:
A poorly enforcedBring Your Own Device (BYOD)policy can lead to the rise ofShadow IT, where employees use unauthorized devices, software, or cloud services without IT department approval. This often occurs because:
* Lack of Policy Clarity:Employees may not be aware of which devices or applications are approved.
* Absence of Monitoring:If the organization does not track personal device usage, employees may introduce unvetted apps or tools.
* Security Gaps:Personal devices may not meet corporate security standards, leading to data leaks and vulnerabilities.
* Data Governance Issues:IT departments lose control over data accessed or stored on unauthorized devices, increasing the risk of data loss or exposure.
Other options analysis:
* A. Weak passwords:While BYOD policies might influence password practices, weak passwords are not directly caused by poor BYOD enforcement.
