Performance testing in databases primarily aims to assess the speed and responsiveness of the database system under various conditions such as heavy loads, concurrent users, or large datasets. Performance testing helps identify bottlenecks and optimize database performance.

Authentication testing involves validating the identity of a user or system to ensure that only authorized entities gain access. Verification is the process of evaluating if the requirements are met, while validation ensures that the system meets the user's needs. Authentication specifically deals with confirming the identity of users or systems accessing a resource. Authorization, on the other hand, pertains to granting access rights based on authenticated identities.

Sending fraudulent emails pretending to be from reputable companies to trick individuals into revealing personal information is known as Phishing. It's a common method for cybercriminals to obtain sensitive data.

The strategy of "Least Privilege" focuses on limiting access to information and resources to only those individuals who require it to perform their job functions. This minimizes the potential for insider threats as employees only have access to what's necessary for their role.

The scenario highlights the importance of human behavior in cybersecurity. An educated and vigilant workforce can play a crucial role in identifying and reporting potential security threats, such as phishing attempts.

Having a documented incident response procedure minimizes the impact of a security incident. It enables an organized and efficient response, reducing downtime, data loss, and financial damage. It's crucial for a company's resilience.

Burp Suite is a popular web security assessment tool that focuses on spidering and analyzing web pages to find potential vulnerabilities. It's widely used for web application security testing, including scanning for common web vulnerabilities like SQL injection and Cross-Site Scripting (XSS).

A popular tool used to identify vulnerabilities in web applications by scanning their source code is called a "Static Application Security Testing (SAST)" tool. SAST tools analyze the source code to identify security issues and vulnerabilities early in the development process.

A "DDoS" attack stands for Distributed Denial of Service and is designed to make a service unavailable by overwhelming it with traffic, often from multiple sources.

Hacktivists are individuals or groups that use hacking skills to promote political or ideological causes. They're motivated by beliefs rather than financial gain. Insider Threats are employees with access to sensitive data, Cybercriminals seek financial gain, and Script Kiddies are amateur hackers.
