What are the top security vulnerabilities you have encountered in your previous role and how did you mitigate them?

Top Security Vulnerabilities Encountered and Mitigated

During my previous role, I encountered several security vulnerabilities that required immediate attention and mitigation. Some of the top vulnerabilities included:

1. SQL Injection: This vulnerability allowed attackers to manipulate database queries through user inputs. To mitigate this, I implemented input validation, parameterized queries, and regularly updated our database security measures.
2. Cross-Site Scripting (XSS): XSS attacks allowed malicious scripts to be injected into web pages viewed by other users. I mitigated this vulnerability by encoding user inputs, validating data on the client and server side, and using secure HTTP headers.
3. Unauthorized Access: This vulnerability allowed unauthorized users to access sensitive data and resources. To mitigate this, I enforced strict access controls, implemented multi-factor authentication, and regularly audited user permissions.

By proactively identifying and addressing these vulnerabilities, I was able to strengthen the security posture of the systems and infrastructure in my previous role, ensuring the confidentiality, integrity, and availability of sensitive data and resources.
