4 Factors to Consider When Creating a Network Security Engineer Job Description That Fits Your Needs

In the realm of cybersecurity, network security engineers play a pivotal role in safeguarding your company's digital assets. With the vast number of professionals in the field, pinpointing the right candidate necessitates a clear understanding of your specific security needs. Here are some vital factors to bear in mind to ensure you enlist the ideal network security engineer for your business:

Area of Expertise

Network security engineers specialize in various domains, including but not limited to firewall management, intrusion detection systems, cryptography, risk assessment, cloud security, and network protocols. Each engineer has a unique set of skills tailored to different aspects of network security. It's crucial to identify the specific expertise required for your project or organizational needs to ensure optimal protection and efficiency.

Employment Type

There are several ways to integrate a network security engineer into your team: hiring in-house, contracting through a cybersecurity firm, or engaging a freelancer. In-house engineers offer consistent, dedicated support for ongoing security management but require significant investment in recruitment and training. Contracting through a firm provides access to a pool of experts for specific projects or to address immediate threats, although it may be costly for long-term engagements. Freelancers offer flexibility and can be a cost-effective solution for short-term projects or specialized tasks.

Experience Level

The complexity and sensitivity of your network security needs will dictate whether a junior or senior network security engineer is more appropriate. Junior engineers, while less experienced, are adaptable and can grow with your organization, making them suitable for less critical operations. In contrast, senior engineers bring a wealth of knowledge and experience for managing high-stakes security environments, capable of navigating complex challenges and making strategic decisions.

Industry-Specific Knowledge

Network security concerns vary significantly across different industries, such as finance, healthcare, retail, and government. Each sector faces unique regulatory requirements and threats. Hiring a network security engineer with relevant industry experience ensures a deeper understanding of specific challenges and compliance standards, enhancing the effectiveness of your security measures.

Portfolio and Credentials

A candidate's portfolio, along with certifications such as CISSP (Certified Information Systems Security Professional), CISM (Certified Information Security Manager), or specific vendor certifications, can provide insights into their expertise and experience. Certifications confirm a professional's knowledge and commitment to the field, while a portfolio of past projects highlights their practical skills and achievements.

Next Steps

Armed with these considerations, you're well-equipped to start your search for the perfect network security engineer. Platforms like LinkedIn or niche cybersecurity job boards can offer a curated list of candidates, showcasing their skills, experience, and certifications to help you make an informed decision.

By carefully evaluating these factors, you can ensure that you hire a network security engineer who not only meets your current needs but can also adapt and respond to evolving cybersecurity challenges.

Hey, I'm James. I've been a self-employed business network and server admin for 25+ years. I've worked with all flavors of Linux and Windows for some of the best businesses in the country. My average customer that I've worked with has been with me over 15 years. I specialize in analyzing current infrastructure and determining the needs of my clients then providing a written plan to correct any issues and protect the business systems from hackers and cryptolockers. In one of my recent projects, I consulted with a six billion dollar, publicly traded company to completely redesign their infrastructure to have redundant firewalls, VMWare host servers, leased fiber lines directly to Amazon AWS with a VPN backup over a regular Internet circuit that would automatically fail over in case of any circuit issue. The vmware servers would auto migrate the guests in the case of overload or host server failure. All power systems were redundant with two powersupplies for each piece of equipment. At the end of this project, we had reduced their monthly cost of management by over 25,000 per month and reduced their server load from over 20 servers to just 8 servers. When you hire me, here's what you can expect: 1. First, click the invite button to invite me to your job. 2. Once everything is accepted, I'll jump on the phone or a zoom with you 3. We'll go over the details of the job and I'll ask questions to drill down to the specific goals you want to accomplish. 4. I'll provide you with a high level written plan to address your goals along with expected time needed to complete your project. 5. When we agree on the timeline and process, I will execute the plan. So, if this sounds good, just click the "invite" button and we can start.

I specialize in writing Network Automation Infrastructure code, Network applications and System software for Linux and "Unix-like" OS's. The tools of my trade are Ansible, Python, C and C++. My Perl and shell-scripting skills aren't too bad either. I worked for more than 18 years at Cisco Systems, where I wrote software applications for IOS and IOS-XE switches and routers. In the process, I developed a deep understanding of how packets move, and about the boxes that make packets move. Outside of Networking, my areas of expertise include Linux and Embedded systems. I have hands-on experience with OpenStack and Docker. I have an understanding of Cloud Networking in the context of OpenStack Neutron. I possess decent writing skills, and a couple of my technical articles on the web register a few dozen hits every day. I take pains to document my work and explain them to my clients. I have received feedback telling me that I should have been a teacher. I have the ability to explain whatever I know in a clear manner free of jargon. I have 25+ years' overall experience in the software industry as a hands-on programmer. I've never been a people manager: all I've done for 25+ years is write, test, debug, deploy and support code. People familiar with my working style would describe me as "careful, methodical, systematic and logical" rather than "brilliant", "flamboyant" or "genius". Portfolio: ********** I divide my time between building solutions for my clients, creating open-source projects and writing the occasional article on programming network applications. My client projects include: - a set of Ansible playbooks (about 300 tasks in all) to install and configure an OpenStack instance on a single computer. The playbooks were embedded inside a Docker container, and running the container would start the ansible-playbook runs. The use-case was an IoT Edge installation, where the OpenStack instance would house VMs to run analytics on data coming from sensors. - an Ansible playbook to deploy and configure VyOS routers in an VmWare ESXi environment. Involved creating the router instances, creating VRFs and other related configuration. - a "domain name catcher" for Nominet in C: the work involved studying packet capture (PCAP) files using Python, running analysis using NumPy and matplotlib on the packet data, and using the insights thus obtained to tweak the behaviour of the C program. - use of profiling techniques to dramatically improve the performance of a C++ desktop network application: my client had a program that would scale poorly as the number of network hosts increased, which I was able to fix after studying the profiling results and reworking the data structures used in the program - a Perl interface to access Google Analytics - post-parsers in Python to process Google Vision API JSON outputs I am the author of several open-source projects, including: - an Ansible role that configures AAA, Layer-2, Layer-3, QoS and Netflow on a Cisco Catalyst switch. This makes extensive use of Jinja2 templates to generate the IOS configuration based on variables stored in YAML - a lookup plugin for Ansible that expands strings of the form "Gi3/1-4,Gi4/1-4" and generates a list of full individual interface names. This is extremely handy when writing Network Automation playbooks, for applying a configuration on a set of interfaces. - a Python PCAP to CSV converter (extracts fields from a PCAP file and populates the rows of a CSV document) - a Network Automation demo repository, where I have code to perform a particular network configuration task (creating a VLAN, its associated Layer 3 interfaces, IPv4 subnets and OSPF networks) using multiple approaches: Python (using the netmiko module), NETCONF/YANG, Chef, Puppet and Ansible I have a couple of fairly popular technical articles online: an article on Network Automation using various approaches, and one on using Python programming techniques to analyze packet capture (PCAP) files. Some examples of what I can do for you: ********************************************** - write/test/debug/deploy network automation code (Ansible playbooks, Python scripts etc.) - write/test/debug/deploy network applications, tools and utility scripts (in C, C++ and Python - Perl and bash/Bourne shell as well) - use standard GNU tools like gcc, gdb, gprof, gcov and make to build system software in C and C++ - create technical articles, blog posts, training material etc. on Networking and Network Automation - port open-source C/C++ projects to your platform
