Network Security Engineer Jobs


What is a network security engineer?

Network security engineers have an in-depth knowledge of the construction and implementation of complex security systems to protect a business from intrusion.

This is a more specialist role, meaning applicants will typically need a number of years’ experience in cyber security before being considered.

Network security engineers are expected to plan, develop and create new defensive security systems and then support other members of staff in using them to ensure the safety of the business is as tightly defended as possible.

What does a network security engineer do?

To start with, network security engineers will need to have a detailed knowledge of the organisation’s security frameworks, including the Local Access Network (LAN), Wide Area Network (WAN) and any Virtual Private Networks (VPN).

Once you have a deep understanding of the system that already exists, you will likely be expected to construct a new system to provide more robust, up-to-date security for the organisation.

Typical job duties include:

  • Planning

With a detailed knowledge of the current network security system, you will be able to plan new frameworks which help tackle identified flaws or potential issues to bring the system in line with the most up-to-date threat management practices of the industry.

Senior network engineers will likely be expected to manage the project of implementing new systems throughout their lifetime.

  • Design

Once the plan has been agreed, you will then be expected to start designing the infrastructure to best suit the needs of the business. Knowledge of existing weaknesses or flaws will be vital here as you will need to ensure that your new designs take these issues into account and act to reduce them going forward.

  • Implementation

As the security engineer, you will then need to implement the new system in its entirety, including physical implementation of new hardware and the implementation of software across LAN, WAN and VPN.

You will also then need to test the implemented systems, organising bug fixes and dealing with issues that may arise.

  • Maintenance

Once implemented, you may be responsible for the monitoring and maintenance of this system. This will include how effective it has been at tackling previously identified issues and how successfully related members of the business are able to operate it.

What is the average salary of a network security engineer?

Network security engineers make on average £38,000 in the UK. In the US, $85,000 is the average salary, with $56,000 standing at the lower 10% of the spectrum.

What qualifications will I need for this role?

Employers will usually expect a degree in a related field to cyber security, such as mathematics or computer science. However, those with substantial relative experience will also often be considered for the role of network security engineer.

Some common professional qualifications include:

  • Certified Ethical Hacker (CEH)
  • Certified Information Systems Security Professional (CISSP)
  • GIAC certificates such as the GIAC Certified Intrusion Analyst (GCIA)

How do I become a network security engineer?

This is a specialist role, meaning those considering applying will need to have a number of years’ experience in the field of cyber security. Those typically considered for the role will have experience in the construction and implementation of security systems as part of a team.

You may also be considered for this role with previous experience in penetration testing and security architecture.

Since this is a network security role, experience with LAN, WAN and VPN is essential.

How do I become a cloud security engineer?

A cloud security engineer is an engineer employed specifically to design a network infrastructure for cloud systems used by an organisation. Businesses which use cloud software or are in the process of implementing new software will need to consider the specific security issues which come with the cloud.

To be successful in this type of role you will need to have an in-depth knowledge of cloud security best practice and extensive knowledge of cloud systems, coding and threat management.
