Security+ is moderately hard: it's entry level, but it's broad, the wording is precise, and the performance-based questions (PBQs) test whether you can apply what you know. People with some IT background and a few weeks of structured study pass it routinely. People who try to memorise acronyms the night before usually don't.
Why it's harder than it looks
- Breadth. Five domains covering everything from cryptography and PKI to governance and incident response.
- Close distractors. Questions often have two answers that are both "security things"; only one fits the scenario exactly. Know what each control or attack is, not just its name.
- Performance-based questions. Simulations where you configure, order or match. They're slow if you haven't practised the format.
- "Best" and "first" questions. Several answers may be reasonable; the exam wants the best or the first step, which depends on knowing the process order.
The domains that trip people up
- Security Operations (28%): the largest domain, with incident response, monitoring, vulnerability management and IAM.
- General Security Concepts: cryptography and PKI are where non-specialists lose marks.
- Security Program Management: agreement types and risk terms are pure definitions, easy to underestimate.
Who finds it easier
- People in help desk, sysadmin or networking roles, especially with Network+ or similar knowledge.
- Anyone who has worked through real incidents or vulnerability scans.
How long people prepare
Typical ranges: four to six weeks for people with IT experience; two to three months for career changers new to IT. Readiness is better measured by steady practice-exam scores of 80–85% than by time, plus being comfortable with PBQ-style tasks.
A sensible plan
- Take the free Security+ diagnostic.
- Read the Security+ cheat sheet and learn the domains in weight order.
- Work through the domain pages, weakest first: threats, architecture and the three above.
- Finish with full timed practice exams, flagging PBQs first to practise your time management.

Frequently asked questions
Is Security+ hard for beginners?
It's challenging but passable. Beginners usually need two to three months of structured study, because the exam covers a wide range of topics and uses precise wording.
What is the hardest part of Security+?
For most candidates: the performance-based questions, cryptography and PKI, and 'best' or 'first' questions that depend on knowing process order.
Is Security+ harder than A+?
Most people find Security+ harder: it's narrower than A+ but deeper, with more scenario-based questions.
