Cumulus Systems Information Security Analyst Interview Questions and Answers

SQL injection is a code injection technique that attackers use to exploit vulnerabilities in a database-driven application.

• SQL injection occurs when an attacker inserts malicious SQL code into a query, allowing them to manipulate or extract data from the database.

• It can lead to unauthorized access, data breaches, data manipulation, or even complete system compromise.

• To mitigate SQL injection, use parameterized queries ...read more

CSRF stands for Cross-Site Request Forgery, a type of attack where a malicious website tricks a user into performing an action on another website without their knowledge or consent.

• CSRF attacks exploit the trust that a website has in a user's browser

• Attackers can use CSRF to perform actions such as changing a user's password or making unauthorized purchases

• Preventing CSRF involves using techniques such as CSRF tokens a...read more

• XSS attacks can be mitigated by sanitizing user input and output

• Use input validation to ensure that user input is safe and does not contain any malicious code

• Encode user input before displaying it on a web page

• Use Content Security Policy (CSP) to restrict the...read more

SQL injection is a type of cyber attack where malicious SQL statements are inserted into an entry field for execution.
