• SQL injection is a type of injection attack where malicious SQL statements are inserted into an entry field for execution.
• The primary way to prevent SQL injection is by validating and sanitizing user input. This involves checking the input for malicious content and ensuring it adheres to expected patterns.
• Prepared statements (parameterized queries) are also highly effective, as they treat user input as data rather than executable code.
• Implementing these practices ensures that any input received from users does not manipulate SQL queries in a harmful way.

TOR is a network that enables anonymous communication over the internet by routing the traffic through a series of relays or nodes. TOR alters the data content during transit by encrypting it and the destination information over multiple layers, using a technique called onion routing. Each layer of encryption can only be decrypted by a specific relay in the network, which reveals the next destination. This way, no single relay knows the complete path or the content of the data, making it difficult to trace or monitor the communication. References := Cisco Cybersecurity Operations Fundamentals, Module 2: Security Monitoring, Lesson 2.1: The Network as a Sensor, Topic 2.1.3: Network Data Exfiltration Techniques
