Network security interview questions and answers 

Here is a list of the commonly asked questions at a Microsoft Security Engineer interview regarding network security: 

1) What is the difference between a firewall and an intrusion detection system (IDS)? 

Answer: A firewall acts as a barrier between networks, controlling incoming and outgoing traffic based on predetermined rules. An IDS, on the other hand, monitors network traffic for suspicious activities or patterns, providing alerts or triggering automated responses. 

2) How does network segmentation contribute to network security? 

Answer: Network segmentation involves dividing a network into smaller, isolated segments, restricting access between them. This limits the potential impact of a security breach and helps contain the lateral movement of threats within the network. 

3) What is the role of a Virtual Private Network (VPN) in ensuring secure remote access to a network? 

Answer: A VPN establishes an encrypted connection between a user's device and a private network, ensuring secure remote access. It protects sensitive data transmitted over public networks and provides authentication and confidentiality. 

4) What is the purpose of a proxy server in network security? 

Answer: A proxy server serves as an intermediary between clients and servers, forwarding requests and responses. It can enhance network security by providing anonymity, caching content, filtering malicious traffic, and controlling access to specific resources. 

5) What are some common security risks associated with the use of public Wi-Fi networks? 

Answer: Common security risks with public Wi-Fi networks include man-in-the-middle attacks, eavesdropping, rogue access points, and malicious hotspots. It's essential to use VPNs, avoid transmitting sensitive information, and ensure devices have up-to-date security measures to mitigate these risks. 

6) What are the key components of a secure network infrastructure? 

Answer: A secure network infrastructure includes several key components: 

a) Firewalls: These devices monitor and control incoming and outgoing network traffic to protect against unauthorised access and threats. 

b) Intrusion Detection/Prevention Systems (IDS/IPS): They detect and respond to malicious activities or potential security breaches. 

c) Virtual Private Networks (VPNs): They provide secure remote access to network resources over the internet. 

d) Network segmentation: This practice involves dividing the network into smaller, isolated segments to limit the potential impact of a security breach. 

e) Secure Wi-Fi: Implementing strong encryption protocols (such as WPA2 or WPA3) and enforcing secure authentication mechanisms for wireless networks.

Answer: A Virtual Local Area Network (VLAN) is a logical network that allows you to segment a physical network into multiple virtual networks. The few ways in which VLANs enhance network security are: 

a) Isolating network traffic: VLANs ensure that network traffic is segregated, limiting the impact of potential security breaches. 

b) Implementing access controls: VLANs can enforce access control policies to restrict network access based on user roles or groups. 

c) Containing network threats: If a device within a VLAN is compromised, the scope of the breach is limited to that VLAN, preventing lateral movement across the network. 

9) What security measures should wireless networks implement? 

Answer: The following measures should be implemented to enhance the security of wireless networks:  

a) Secure authentication 

b) Encryption 

c) MAC address filtering 

d) Wireless Intrusion Detection/Prevention Systems (WIDS/WIPS) 

e) Regular firmware updates 

10) How do you secure network devices, such as routers and switches? 

Answer: Securing network devices involves several best practices. Some of them are: 

a) Changing default passwords: Immediately changing default passwords upon device installation to prevent unauthorised access. 

b) Strong access controls: Implementing role-based access control (RBAC) and using strong passwords or multi-factor authentication for device access.
