With stronger data visibility, detailed information about the data in real-time is provided. This enhanced visibility allows for a more comprehensive analysis of network traffic, enabling security professionals to identify and mitigate threats more effectively. References := Cisco Cybersecurity Operations Fundamentals

 TOR, or The Onion Router, is designed to conceal a user’s location and usage from anyone conducting network surveillance or traffic analysis. Using TOR makes it more difficult to trace internet activity, including “visits to Web sites, online posts, instant messages, and other communication forms,” back to the user1. It is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their internet activities unmonitored. Within an organization, the use of TOR can decrease visibility into data traffic because it encrypts the data multiple times and routes it through a series of servers operated by volunteers around the globe. This makes network monitoring and data visibility challenging for cybersecurity professionals within the organization. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS)

DDoS attacks are divided into two categories: reflected and direct. Reflected attacks use a third-party system to amplify the attack traffic and send it to the target. For example, an attacker can send a spoofed request to a DNS server, which will reply with a large amount of data to the target’s IP address. Direct attacks send the attack traffic directly from the attacker’s system or a botnet to the target. For example, an attacker can send a large number of SYN packets to the target’s port, exhausting its resources. References := Cisco Cybersecurity Operations Fundamentals, Module 1: Security Concepts, Lesson 1.3: Common Network Application Operations and Attacks, Topic 1.3.4: Denial-of-Service Attacks

 Encryption ensures that data is secure and unreadable to unauthorized individuals without the proper decryption key. It is a critical aspect of maintaining data confidentiality and security, especially in the transmission of sensitive information over potentially insecure networks1.
