What ITS-NS Certification Actually Is
ITS-NS refers to the Information Technology Specialist - Network Security credential, which Pearson lists in its IT Specialist program as "IT Specialist - Network Security." It is a proctored, computer-based exam that verifies a candidate can apply foundational security controls across client operating systems, network devices and everyday computing practices. It is an entry-level, skills-oriented credential rather than an advanced practitioner certification.
The exam is built from a short, official objectives document published by Pearson (the 2025 edition runs two pages). That document describes what a candidate should be able to do, and it reads as a practical checklist: set permissions on Windows and Linux, understand authentication methods, configure auditing, choose encryption approaches, protect wireless networks, distinguish firewalls from intrusion detection and prevention systems, isolate network segments, secure protocols, and practice safer end-user computing.
If you have seen other pages that use the same abbreviation for unrelated credentials, set them aside. This article covers only the Pearson IT Specialist exam. For the shorter definitional pages on this site, see What Is ITS-NS? and What Does ITS-NS Stand For?.
Who Issues It and How It Is Delivered
Pearson is the governing body. Certiport, a Pearson VUE business, administers the exam and issues the credential. Candidates have more than one way to test:
- Certiport Authorized Testing Centers (CATCs): schools, training providers and other organizations approved to proctor the exam. Some CATCs charge a proctoring fee on top of the voucher.
- Pearson VUE delivery: test-center and OnVUE (online proctored) options are also available for IT Specialist exams.
Whatever the channel, expect identity verification, a proctor, and exam-security and non-disclosure rules. Pearson's test-candidate policy governs conduct, and it is worth reading before exam day so that an avoidable policy issue does not cost you an attempt. For scheduling specifics, see ITS-NS Exam Dates 2026.
Exam Format, Length and Scoring
| Item | What the official sources state |
|---|---|
| Question count | Published exam-form range of 35-45 questions |
| Time | 50 minutes standard exam time, excluding administrative appointment activities |
| Delivery | Computer-based and proctored |
| Question style | The official tutorial illustrates multiple-choice items, with review and navigation tools and the ability to change answers before submission |
| Passing score | 700 on a scaled range of 1-1000 |
| Degree requirement | None |
Two details deserve emphasis. First, the question count is a range, not a fixed number, so do not plan around a specific total or a particular split of scored versus unscored items. Second, the 700 passing score is a scaled score. It is not a raw 70% requirement, and you should not try to back-calculate a number of questions you can miss. For a deeper explanation, read ITS-NS Passing Score 2026.
With 50 minutes for roughly 35-45 items, pacing is manageable but not leisurely. Use the review feature to flag uncertain items and return to them rather than stalling early on a single scenario.
The Four Official Domains
The official objective document is organized under four headings. This site preserves them exactly rather than importing a broader cybersecurity syllabus. Note that the study priorities below are editorial judgments, not exam percentage weights; Pearson's objectives as reproduced here do not claim weights.
Domain 1: Defense in Depth
This domain is about layering controls so that no single failure exposes everything. Expect to reason about where a given control sits in the stack and what it does and does not protect against.
- Firewalls, intrusion detection systems, intrusion prevention systems and SIEM, and how each differs in purpose
- Network isolation and segmentation as a containment strategy
- Wireless protection choices and why some are weaker than others
- How preventive, detective and corrective controls complement each other
Domain 2: Operating System Security
The objectives cover both Windows and Linux, so candidates need working familiarity with each rather than depth in only one.
- File and folder permissions on Windows and Linux, including how effective access is determined
- Authentication methods and account protections
- Auditing: what to log and why logs matter after an incident
- Encryption of data at rest and the practical tradeoffs of different approaches
Domain 3: Network Device Security
This domain focuses on securing the devices and ports that carry traffic, and the protocols that run over them.
- Device hardening: default credentials, unnecessary services and open ports
- Secure versus insecure protocols and which secure alternative replaces which
- Isolating network segments to limit lateral movement
- Monitoring and detection devices and their placement
Domain 4: Secure Computing
This covers safer end-user computing and the habits and controls that reduce everyday risk.
- Protecting client systems with security applications and updates
- Backup selection and why it matters for recovery
- Safer browsing, email and removable-media practices
- Recognizing common threats from the user's point of view
For a domain-by-domain breakdown with deeper topic lists, see ITS-NS Exam Domains 2026: Complete Guide to All 4 Content Areas.
What the Questions Ask You to Decide
Because the objectives are application-oriented, the most productive way to study is to practice decisions, not definitions. Representative decision types include:
- Permissions scenarios: A user needs read access to a shared folder but must not modify files. Which permission set achieves that on Windows? How would the equivalent be expressed on Linux?
- Authentication scenarios: Which method adds a second factor, and what weakness does a single password leave open?
- Control selection: A device should block suspicious traffic in line rather than merely alert. Is that an IDS or an IPS function? Where does a SIEM fit in correlating the resulting events?
- Protocol security: Management traffic is traveling in cleartext. Which secure protocol replaces it?
- Backup and encryption choices: A laptop holding sensitive files could be lost or stolen. Which combination of encryption and backup addresses confidentiality and recovery?
Key Takeaway
Turn every objective into a "which control, and why" question. If you can explain why one option beats the plausible distractors, you are preparing at the level the exam rewards.

What This Credential Is Not
Search results blur several similarly named credentials, so precision helps. The Pearson IT Specialist Network Security exam is a separate credential from the following:
| Credential | Relationship to ITS-NS |
|---|---|
| IT Specialist - Cybersecurity | A different exam in the same Pearson program, with its own objectives |
| IT Specialist - Networking | A different exam focused on networking, not on security controls |
| Microsoft MTA | A separate vendor program, not covered by this exam |
| CompTIA Security+ | A separate, broader certification from a different body |
Practice material built for one of these will not map cleanly to another. When evaluating study resources, check that they align to the Network Security objectives specifically. Some publicly visible listings blur Network Security with Networking, which is a reason to verify any resource against the official objective document rather than trusting a title.
Voucher Mechanics, Fees and Retakes
The US individual retail price for the IT Specialist Exam Voucher + Retake is USD 133. Read that figure carefully: it is the price of the voucher bundle that includes a retake, not an exam-only price and not a universal price across every channel or country. A CATC may charge separately for proctoring.
- Original voucher validity: one year from purchase.
- Retake code: if you do not pass, an issued retake code must be used within 60 days of the failed attempt.
- Online CATC service: a separately sold Thrive online CATC service is available for ages 18 and older and requires an active voucher. Its conditions are specific to that service and should not be assumed to apply to school testing or OnVUE.

Validity and Renewal
Awards earned on or after June 18, 2025 expire after five years. Awards earned before that date remain non-expiring. To renew a credential that expires, you purchase a voucher and pass the current version of the exam. Pearson's dated expiration policy takes precedence over older program-page wording that described one-time issuance, so if you see conflicting language, defer to the expiration policy.
Practically, this means the credential reflects a point in time. Plan to re-verify your skills against whatever objectives are current when you renew, because the exam you pass later may differ from the one you sit now.
Who Should Sit This Exam
There is no bachelor's degree requirement and no mandatory provider course. Pearson's candidate profile describes someone with hands-on familiarity with client operating systems, security applications, firewalls, devices and network ports, with at least 150 hours of instruction or practical experience in network security. That 150 hours is preparation guidance. It is not a measured exam requirement and nobody checks it at the door.
The exam suits:
- Students in secondary or post-secondary IT programs who want a recognized, objective-aligned credential.
- Career changers building a first security credential on top of basic IT familiarity.
- Help-desk and desktop-support staff who handle permissions, endpoint protection and user accounts daily.
See ITS-NS Requirements 2026 for eligibility details.
Career and Salary Context
It is worth being candid about what an entry-level credential does and does not prove in the job market. The US Bureau of Labor Statistics reports a May 2025 median of USD 129,180 for information security analysts. That is an occupation-wide figure. It is not a salary for people holding this certification, not an entry-level offer, and not evidence of a pay premium attributable to the credential. Senior security roles drive much of that median.
A more realistic framing: the certification can help demonstrate foundational skills to employers who screen for structured, verifiable knowledge, particularly for support, junior administration and security-adjacent roles. It is one signal among several, alongside hands-on experience and other credentials. For deeper discussion, see ITS-NS Salary Guide 2026, ITS-NS Jobs and Is the ITS-NS Certification Worth It?.
Be equally cautious with pass-rate claims. Institutional cohort results and vendor guarantees do not establish an exam-wide success rate, and this article does not cite one. The context behind that caution is explained in ITS-NS Pass Rate 2026: What the Data Shows.
A Domain-Ordered Preparation Sequence
If you are building a schedule, sequence it by how the domains depend on one another. The ordering below is an editorial suggestion, not a statement about exam weighting.
Operating System Security first
- Practice Windows and Linux permission scenarios until effective access is predictable.
- Cover authentication, auditing and encryption basics, since later domains assume them.
Network Device Security
- Learn secure versus insecure protocols and device hardening steps.
- Map open ports and common services to their risks.
Defense in Depth
- Compare firewalls, IDS, IPS and SIEM side by side using the same scenario each time.
- Work through isolation and wireless protection choices.
Secure Computing and full review
- Drill backup selection and encryption decisions.
- Take timed practice sets against the 50-minute limit and review every rationale, not just wrong answers.
Adjust the pace to your background; someone who administers Linux daily may compress Week 1, while a Windows-only user should expect to spend longer there. For a fuller plan, use the ITS-NS Study Guide 2026, then reinforce recall with the ITS-NS Cheat Sheet. When you want exam-style repetition, work through questions on the ITS-NS practice test site, and use the main practice platform to confirm you can explain each answer choice, not only select it.
