Step 1
Explain the type of access to the statistics file a student on work experience at the company should be given.
Answer
The student should be given 'Read Only' access to the statistics file. This ensures that while the student can view and learn from the data, they cannot modify or delete it, protecting sensitive information and maintaining the data integrity. Allowing 'No Access' would prevent the student from gaining valuable experience and insights.

Burning digital devices to dispose of them can expose workers to toxic fumes, increasing the risk of respiratory issues and other health hazards.
Step 4
Describe what is meant by the term ‘penetration testing’ when applied to networks.
