4. Switches

Here's how network security engineers use switches:
  • Performed installation and configuration of Cisco switches and routers
  • Configured and performed troubleshooting routers and switches.

5. Linux

Linux is a Unix-like operating system. Just like Windows, Mac OS, and IOS, Linux is an operating system used by millions across the globe. Android itself is powered by the Linux operating system. Linux manages all the hardware resources that are associated with your computer. The software is famous because of the protection it grants from viruses, malware, and crashes. The Linux operating system is entirely free and is an open-source software meaning it can be altered by those equipped with the knowledge to code.

7. Routers

A router is a device that gives a computing device the capability to connect to the internet and transfer data between different devices whether at a home or office. It may include several network ports to connect many devices at one go.

Here's how network security engineers use routers:
  • Sanitize, configure and secure outgoing/incoming Juniper/Cisco firewalls and routers as well as Foundry devices.
  • Managed information technology security, including backups, firewalls, and routers.

8. Servers

Servers are computers or systems that provide services to other computers known as clients connected to them via a network. The services can range from data, resources, programs, or any other service that has to do with computing and computers.


It may also refer to someone at a restaurants that delivers the food to patrons from the kitchen.

Here's how network security engineers use servers:
  • Performed a variety of activities in personal computers, application servers, scheduling coordination, systems administration, and data security.
  • Developed and implemented guidelines for telephone support/troubleshooting for both client network and security issues including hardening all servers and firewalls;.

9. TCP/IP

Here's how network security engineers use tcp/ip:
  • Perform network troubleshooting to isolate and diagnose common network problems, using strong TCP/IP networking skills.
  • Utilized Bash shell scripting to implement a TCP/IP data recorder for basic network forensic investigation.

10. ASA

Here's how network security engineers use asa:
  • Experience in Enforcing network security to DMZ & external Market Data vendors via ASA 5500 series firewall rules, and NAT.
  • Provide configuration, design and global support of corporate ASA firewalls, for LAB and remote office design and deployments.

11. Intrusion Detection

Intrusion Detection is the job of an intrusion detection system which is a software application that maintains 24-hour surveillance on a system or network to detect an intrusion or breach of privacy. The system then reports the intrusion to its administrator who then takes necessary steps to prevent the intrusion by activating a firewall or blocking out the violator. They are used in the IT industry mostly and in areas where security is held in high esteem.

Here's how network security engineers use intrusion detection:
  • Assisted both domestic and international customers with implementing RealSecure network-based and host-based intrusion detection software on their individual networks.
  • Deployed, managed and maintained security systems including firewalls, intrusion detection systems, and anti-virus software.

12. SIEM

Here's how network security engineers use siem:
  • Identify and respond to security incidents that affect customer network utilizing Security Incident and Event Management (SIEM) tools.
  • Collected log data from network hardware devices and its behaviors in SIEM tools for having real-time analysis of security alerts.

13. Network Infrastructure

Here's how network security engineers use network infrastructure:
  • Provide support for Network Security Management Team that is responsible for providing systems implementation and support for the network infrastructure security.
  • Created policies and standard operating procedures for incident response, network vulnerability scanning, and security testing of network infrastructure.

14. IOS

iOS stands for "iPhone operating system," which is the operating system used in Apple phones and other mobile devices. This system, along with the software development kit Apple released, allows app developers to design new applications specifically for Apple devices. Because of the specific operating system, many applications designed using iOS are not compatible with devices that use a different system.

Here's how network security engineers use ios:
  • Implemented software platform that is responsible for configuration management, IOS upgrades and compliance checks for all network devices.
  • Participate in the testing of newer IOS versions to identify potential issues with implementation on the American Express network.

15. Azure

Here's how network security engineers use azure:
  • Aided in design and construction of hybrid cloud environment with Microsoft Azure for hosting client servers and services.
  • Configured Site-to-Site connection in the Azure portal Experience in the AWS cloud networking like VPC, Direct Connect, etc.

It again depends on what the graduate sees as their next step - graduate school or a job with a company or lab. If the next step is graduate school, the graduate should investigate what they are interested in pursuing and then where the best school is to get the experience that the graduate thinks he or she wants.

General reading about technologies or reading available articles about subjects the graduate is interested in will help generate questions they can ask potential graduate schools. This time would also be a chance to improve areas where the graduate may feel weak while an undergraduate. Many online resources can help them brush up on week background topics. Do not worry about transfer credits because that is usually not helpful in graduate school, but improve knowledge and experience in areas where the graduate feels weak. If the graduate has identified a graduate school and program to study in, the graduate school might have some recommendations about what to review. All of this will help improve success in graduate school.

If the next step is a job with a company or lab, taking courses to improve communication will help. Many technically competent or even technically brilliant people struggle with effective communication. Techniques about writing reports, making oral presentations, or communicating technical information will help improve success. The gap year also provides time to investigate technologies that the graduate wants to be involved in and the companies or labs in those areas.

Once the graduate has identified areas of interest and companies or labs that the graduate might want to work for, they can be contacted to either answer questions or point the graduate in a direction for further investigation.

In either case, a gap year can provide a chance to refine the graduate's choice for the next steps and help them prepare other skills overlooked during the undergraduate years.

What type of skills will young Network Security Engineers need?

John RingJohn Ring LinkedIn Profile

Director Engineering Outreach, Elon University

While our universities consistently educate engineering students with hard skills and strong engineering fundamentals, tomorrow's engineers need to be strong communicators, collaborators, and critical thinkers. Our professional environments are filled with data and information, and the constraint is typically how much time individuals can dedicate to solving a problem. At Elon University, we educate tomorrow's engineers to have the hard skills necessary to analyze the information and situations, apply critical thinking techniques to determine ways to solve the issue, and then concisely and efficiently communicate with colleagues as solutions are being set in motion.
