Technical Expertise Questions

You’ll need to prove your knowledge and capabilities related to network security engineering and cloud architecture. Be ready to get into the technical nitty gritty.

Q: What are some ways to protect data in the cloud?

A: Cloud security best practices to mention include:

  • Encrypting data at rest and in transit using keys only users have access to
  • Leveraging role-based access controls, multi-factor authentication, and strong password policies
  • Monitoring activity logs for unauthorized access attempts
  • Enabling auto-scaling to maintain defenses under increased load
  • Regularly patching and updating systems, software, and applications

Q: How does a VPN create a secure tunnel on a public network?

A: Concisely explain the VPN process:

  • VPN clients connect to a VPN gateway/concentrator via an encrypted tunnel
  • The VPN uses the tunneling protocol to encapsulate and encrypt all traffic with security keys
  • This creates a virtual private network overlaid on the public network infrastructure
  • Traffic is only decrypted at the receiving endpoint, keeping data secure

Q: What experience do you have with security information and event management (SIEM) tools?

A: Share specific SIEM platforms you’ve worked with:

  • “I have 3 years of experience administering Splunk, including managing our log data inputs, monitoring dashboards, configuring alerts and reports, and using statistical analysis to optimize detections.”

  • “I implemented the Sumo Logic platform at my last company from the ground up. This involved ingesting a high volume of data from across our infrastructure, building custom dashboards, and developing searches and alerts.”

Q: How would you go about security hardening a network?

A: Demonstrate you understand key principles like:

  • Performing an asset inventory to understand potential vulnerabilities
  • Locking down access with ACLs, password policies, multi-factor authentication
  • Encrypting and backing up critical data
  • Installing latest patches, disabling unnecessary ports/services
  • Implementing firewalls and edge security controls
  • Developing an incident response plan for scenarios like DDoS attacks

Q: What experience do you have with web application firewalls?

A: Share specifics on the WAF products you’ve worked with:

  • “I deployed Imperva WAF for a healthcare company and tuned it to block SQL injection, cross-site scripting, and other OWASP top 10 vulnerabilities.”

  • “I managed Palo Alto Networks WAFs in my previous role. I optimized the rulesets based on our app traffic patterns to maximize threat prevention without impeding legitimate requests.”

Q: How does TLS/SSL encryption work?

A: Concisely explain the handshake process:

  • The client sends a “ClientHello” with supported TLS versions, ciphers
  • Server responds with certificate, “ServerHello” confirming choices
  • Client verifies certificate signature against CA’s public key
  • Client generates symmetric session key and encrypts with server’s public key
  • Server decrypts symmetric key with private key to establish secure session

Q: What firewall architectures are you familiar with?

A: Mention architectures like:

  • Next-gen/NGFW like Palo Alto combining signatures and heuristics for deeper inspection
  • Proxy based architectures that break and inspect traffic flows
  • Stateful inspection monitoring connection/session data like SYN/ACK
  • Cloud firewall services like AWS security groups or Azure Firewall

Q: Which is the better security measure, HTTPS, or SSL?

A: HTTPS, which stands for “Hypertext Transfer Protocol Secure,” is HTTP mixed with SSL. It encrypts a user’s browsing activity and makes it safer. SSL (Secure Sockets Layer) is a protocol that protects Internet conversations between two or more parties. While they are all pretty safe, SSL is the best when it comes to security. However, all of these are informative for web developers.
