Cybersecurity Analyst Job in USA for 2026 Full Guide

Cybersecurity Analyst at SDS International (Omaha, NE): What This Job Asks For and How to Prepare

I once read a job posting that said “5 years of experience” and closed the tab. Two weeks later I learned that “or equivalent experience” in those postings is often more flexible than it looks. This SDS International listing has that same line, so it’s worth a proper look before you decide to skip it.

Here’s the position, what the tools mean, and how to build the skills yourself.

Quick overview of the listing

Company: SDS International, Inc.
Role: Cybersecurity Analyst
Location: Omaha, Nebraska (on-site)
Type: Full-time
How to apply: Responses are handled off LinkedIn. The posting asks you to email your details to the contact address listed (bamiller@sdslink.com).
Key requirements: Endpoint security with ACAS, threat hunting and risk analysis, intrusion detection systems, and DISA STIGs

One caution first: the listing shows it was posted about a year ago and had a lot of applicants. Check that it’s still open on the company’s site (sdslink.com) before you spend an evening on a tailored resume. A short email asking whether the position is still available costs nothing.

Decoding the experience requirement

The posting asks for five years of relevant experience with Air Force or industry cybersecurity standards and system accreditation. It also accepts equivalent experience with NIST security standards.

That means someone who has worked with the NIST framework (800-53 controls, the Risk Management Framework) may be considered even without a military background. I can’t promise how strictly the hiring team reads it, but the wording leaves room.

Roles like this one often involve government or defense-related systems, which can mean background checks, citizenship rules, or security clearances. The Omaha area is also home to Offutt Air Force Base. The listing doesn’t state clearance requirements, so ask about them in your first email. Don’t assume.

The four skills, in plain English

Most of the buzzwords here sound scarier than they are.

1. ACAS (Assured Compliance Assessment Solution)
This is the Department of Defense’s vulnerability scanning setup, built around Tenable products. You scan machines, get a list of weaknesses, and help decide what gets fixed first. If you’ve ever run a Nessus scan, you’ve touched the core of it.

2. Threat hunting and risk analysis
Alerts tell you something already tripped a wire. Hunting means going looking for trouble that didn’t trigger anything: odd logins at 3 a.m., a workstation talking to a strange IP, a service running that nobody installed. Risk analysis is the other half: deciding which problems actually matter.

3. Intrusion detection systems (IDS)
Tools like Snort, Suricata, and Zeek watch network traffic and flag suspicious patterns. Your job is to tell real threats from noise, which is harder than it sounds.

4. DISA STIGs
Security Technical Implementation Guides are detailed checklists from the Defense Information Systems Agency. They tell you exactly how to configure a system securely: this registry setting, that password policy, this service disabled. The work is tedious, and employers value people who can do it carefully.

How to build these skills at home (mostly free)

You can’t get ACAS the way you’d get a Netflix subscription, but you can practice the same skills with free tools.

Step 1: Set up a small lab

Install VirtualBox or VMware Workstation Player. Create two or three virtual machines: a Windows one, a Linux one, and one for your tools. Keep them on an isolated network. Never scan systems you don’t own or have permission to test.

Step 2: Learn vulnerability scanning

Install Nessus Essentials, the free Tenable version that covers a small number of IP addresses. Scan your lab machines and read the report. For each finding, ask what the weakness is, how an attacker could use it, and how you’d fix it.

Write your findings in plain language. A scan report nobody can understand isn’t useful, and explaining things clearly is half this job.

Step 3: Practice with STIGs

Download the free STIG Viewer and the STIG files for Windows or Ubuntu from DISA’s public site (public.cyber.mil). Pick a hardening checklist and apply it to a test VM. You’ll see how strict these settings are, and sometimes how a “secure” setting breaks something else.

You can also try the SCAP Compliance Checker (SCC), which scans a system against a STIG automatically.

Step 4: Get hands-on with an IDS

Install Security Onion, a free Linux distribution that bundles Suricata, Zeek, and dashboards for reviewing alerts. Generate some traffic, run a harmless test scan against your lab machine, and watch what shows up. Seeing your own activity appear as an alert teaches more than any article.

Step 5: Try basic threat hunting

Open Wireshark and capture traffic on your lab network. Look for patterns: repeated failed connections, unusual ports, DNS requests to odd domains. Then pull Windows event logs and look for repeated failed logins. Write down what you checked and what you found. That write-up becomes proof of skill.

Step 6: Learn the NIST basics

Read the overview of NIST’s Risk Management Framework and skim the control families in SP 800-53 (access control, audit, incident response, and so on). You don’t need to memorize them. You need to speak the language in an interview.

How to word your resume

Don’t just list “ACAS, STIGs, IDS.” Show the work. A line like this beats a keyword list:

“Built a virtual lab; scanned Windows and Linux hosts with Nessus; applied DISA STIG hardening guidelines and documented remediation of 30+ findings.”

Use only numbers that are true. Hiring teams can tell when a resume is padded, and an interviewer will ask you to explain every line.

Also consider certifications. CompTIA Security+ is widely required for defense-related IT jobs, so it’s a common baseline. Others that come up are CySA+ and, later, CISSP.

Mistakes to avoid

Applying blindly. One generic resume to a hundred jobs rarely works. Mirror the listing’s language where it’s honest to do so.
Ignoring the email-only application. This one asks you to email your details. Write a proper short email with a clear subject line, a few sentences on your relevant skills, and your resume attached. Don’t send a blank message with a file.
Claiming tools you’ve never opened. If you’ve only read about ACAS, say so, and describe the similar tools you’ve actually used.
Skipping the documentation habit. Compliance work lives on paperwork. Show you can write clearly.
Scanning networks you don’t own. It can get you in legal trouble. Stay inside your lab.
Skipping the clearance question. Find out early whether the role needs one, so you don’t waste time on both sides.

A short email template

Keep it simple:

Subject: Application – Cybersecurity Analyst (Omaha)

Hello,

I’m applying for the Cybersecurity Analyst position. I have hands-on experience with vulnerability scanning, STIG-based hardening, and IDS monitoring in a lab environment, and I’m studying NIST standards. My resume is attached. Could you confirm whether the position is still open and whether it requires a security clearance?

Thank you,
[Your name]

Is it worth applying?

If you have defense or government IT experience, yes, quickly. If you’re earlier in your career, it’s still worth a try, but go in realistic: the listing is explicit about experience and shows a high applicant count. Even if this particular job doesn’t work out, the skills on the list (vulnerability scanning, STIG compliance, intrusion detection, threat hunting) show up in a huge number of security jobs. Building them is never wasted effort.

Start with the lab this weekend. A scan report you made yourself is worth more in an interview than a long list of buzzwords.
