Secure Networking

5 minutes 5 Questions

Secure Networking involves the implementation of network designs, protocols, and security measures to protect an organization's networks from cyber threats. Security+ covers key concepts such as network architecture, secure network protocols, network segmentation, and security devices like firewalls, intrusion detection and prevention systems, and VPNs. The course also emphasizes the importance of constant monitoring for anomalies, adherence to recommended network security standards, and effective network incident response. Secure Networking enables organizations to protect their critical assets from unauthorized access, maintain the availability of their services and minimize the risk of security breaches.

Secure Networking Guide

Secure Networking is a crucial part of CompTIA Security Plus. It refers to the protection of a computer network from intruders, whether they be targeted attackers or opportunistic malware.

Importance:
Secure Networking's importance lies in its ability to protect sensitive data and ensure the smooth running of systems connected through the network. Failure to secure a network can leave it vulnerable to attacks, data theft, and operational disruptions.

Working:
A secure network works by employing multiple layers of network security measures. These include firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and secure network architecture. These work in synergy to deflect attempted attacks, detect and respond to active threats, and minimize the potential damage from any breaches.

Exam Tips:
When answering questions on Secure Networking in an exam:
- Understand the fundamental concepts such as the purpose of firewalls, IDS, IPS, and secure network architecture.
- Follow a systematic approach to problem-solving. This includes identifying the issue, suggesting a suitable solution, and explaining why that solution was chosen.
- Be aware of the latest developments in network security technology.
- Review past questions and answers to get a feel for what you can expect.

The key to exam success when dealing with Secure Networking is a sound understanding of the principles at play and the ability to apply that knowledge to novel scenarios.

Question 1

A managed service provider (MSP) is responsible for securing a client's network. The client has multiple subnet networks and requires a secure connection between them. What is the best way for the MSP to provide a secure connection?

Use port aggregations on the switches connecting the subnets Use VPN tunnels to connect separate subnet networks Implement a proxy server to connect the subnet networks Enable network address translation (NAT) between the subnets

Correct Answer: Use VPN tunnels to connect separate subnet networks

Connecting the separate subnet networks using VPN tunnels is the best solution. VPN tunnels provide a secure and encrypted connection between different networks. The wrong answers might provide some level of network connectivity or security but do not offer the same secure connection that a VPN tunnel provides.

Question 2

A network administrator is tasked with limiting access to files stored on a file server. They need to ensure that only the appropriate employees have access to specific folders and files according to company policies. What is the best solution to achieve this requirement?

Use the principle of least privilege for sharing permissions Create separate VLANs for different departments Implement role-based access control (RBAC) on the file server Disable read/write permissions for all users

Correct Answer: Implement role-based access control (RBAC) on the file server

Implementing role-based access control (RBAC) on the file server is the correct solution. RBAC ensures that users only have access to the files and folders they are authorized to see. The wrong answers don't provide the necessary level of granular control or security measures for managing access to files on the file server.

Question 3

A company hosts SCADA equipment on their network, which requires uninterrupted operation. To prevent unauthorized access to this equipment, the company decides to segment the network appropriately. What is the best segmentation method?

Create a DMZ for the SCADA equipment Use a virtual local area network (VLAN) for the SCADA equipment Disable the firewall in the SCADA equipment's location Connect the SCADA equipment to the main office switch

Correct Answer: Create a DMZ for the SCADA equipment

Creating a DMZ for the SCADA equipment is the correct solution. A DMZ provides a separate zone for SCADA equipment and isolates it from unauthorized access by creating a separate security layer. The wrong answers either do not provide the required level of segmentation or do not offer secure solutions for protecting the SCADA equipment.
