Scenario: You are a security analyst conducting a penetration test on a web application. During your testing, you discover that the application is vulnerable to SQL injection. What is the responsible and ethical course of action you should take?
- Attempt to exploit the vulnerability further to understand the extent of the damage and gather evidence before reporting it.
- Document the vulnerability and its exploitation details for future reference without informing anyone.
- Immediately inform the relevant stakeholders, including developers and management, about the vulnerability and recommend urgent patching.
- Keep the vulnerability undisclosed to avoid panic and wait for a scheduled patch release to address it.
The responsible and ethical course of action in this scenario is to immediately inform the relevant stakeholders about the vulnerability. Rapid disclosure allows the team to address the issue promptly, minimizing the potential damage from exploitation. Delaying or withholding information could exacerbate the risk of a successful attack.
During database table testing, you find that certain columns lack appropriate indexing, resulting in slow query performance. How would you optimize the database tables to improve query performance?
- Add Indexes; Identify frequently queried columns and apply appropriate indexes
- Denormalize Tables; Combine related tables to reduce query complexity
- Increase RAM; Allocate more memory resources to the database server
- Optimize Queries; Rewrite SQL queries to improve efficiency
Inefficient query performance due to lack of appropriate indexing can be addressed by identifying frequently queried columns and adding appropriate indexes to them. This optimization technique helps the database engine locate and retrieve data more efficiently, resulting in improved query performance.

- Extraction
- Loading
- Migration
- Transformation
Transformation is the stage in ETL (Extract, Transform, Load) process where data is converted or modified according to business rules and requirements before loading it into the target system.
