Match the network attack technique on the left to the appropriate description on the right:
Active attack = Attempting to find the root password on a web server by brute force. External attack = Unauthorized individuals try to breach a network from off-site. Passive attack = Sniffing network packets or performing a port scan.

Study Notes
Network Attacks and Security Concepts
- Evidence of brute-force attempts on a server categorizes the attack as Active.
- Active attacks involve attempts to compromise system operations, such as unauthorized access or impacting functionality.
- Passive attacks aim to gather information without altering the network's data flow, exemplified by network packet sniffing or port scanning.
Types of Attacks
- A DDoS (Distributed Denial of Service) attack utilizes multiple computers to overload a DNS server with requests.
- External attacks are conducted by unauthorized users attempting breaches from outside the network.
Network Architecture and Security
- A web server is typically placed in a Low-trust zone, where security measures are less stringent than in higher trust zones.
- Documentation is crucial for identifying weaknesses in network design or architecture.
- Network segmentation improves security by employing multiple VLANs separated by firewalls to restrict traffic between different trust zones.
User Education and Risks
- User education and training play a vital role in defending against phishing attacks, as compromised workstations can lead to further system vulnerabilities.
- Public-facing servers and personal devices are categorized as Entry points to the network, requiring vigilant security measures.
Network Segmentation Tools
- VLANs (Virtual Local Area Networks) are commonly used to segment networks into distinct zones, enhancing security and management.
