Iso Iec 15408 Pdf Guide

I notice you're asking me to "develop a post" related to the ISO/IEC 15408 standard (also known as "Common Criteria").

However, I cannot directly provide or link to a PDF copy of the ISO/IEC 15408 standard, as it is a copyrighted document owned by ISO and IEC. Sharing unauthorized copies would violate intellectual property laws.

What I can do instead is help you create a useful, informative post about ISO/IEC 15408 that you could share on a blog, LinkedIn, or internal knowledge base — without including the actual PDF.

Here is a draft post you can use or adapt: iso iec 15408 pdf

Part 6: Common Mistakes and Pitfalls (Avoid These)

As a security consultant, I have seen organizations waste six figures because they misunderstood the ISO IEC 15408 PDF. Avoid these errors:

Mistake #1: Using a 2005 PDF in 2025. The attack landscape has changed. The 2022 version adds requirements for side-channel attacks (timing, power analysis) and updatable products (how to handle automatic updates). An old PDF will miss these.

Mistake #2: Confusing EAL with "more secure." EAL7 vs. EAL4 does not mean the product is "more secure" against hackers. It means the development process was more rigorous. A poorly configured EAL5 product is less secure than a well-administered EAL2 product. I notice you're asking me to "develop a

Mistake #3: Forgetting the "Maintenance" chapter. The PDF includes strict rules about what happens after certification. If you ship a product with a new cryptographic library and do not tell the lab, your certificate is void.

Mistake #4: Downloading unofficial PDFs from forums. Many forum-shared PDFs are missing Annexes (e.g., Annex A – Cross-referencing tables). These annexes are critical for mapping functional components. Without them, the standard is nearly unusable.

Limitations and Considerations

• Certification cost and time increase substantially with higher EALs.
• A certified product’s assurance is limited to the evaluated configuration and documented assumptions about the operating environment.
• The CC focuses on specified functionality and assurance evidence; it does not guarantee absolute security in all operational contexts.

For Compliance (Auditors)

The PDF is your checklist. The "Evaluation Methodology" (a separate but related document) tells you exactly how to prove a product meets FAU_GEN.1 (Audit data generation). Part 6: Common Mistakes and Pitfalls (Avoid These)

Part 3: Security Assurance Components (250+ pages)

This lists the Evaluation Assurance Levels (EAL) from EAL1 to EAL7.

• EAL1: Functionally tested (quick check).
• EAL4: Methodically designed, tested, and reviewed (Commercial sweet spot).
• EAL7: Formally verified design and tested (Military/government crypto).
• Why search here: Project managers use this to decide how much money to spend on certification.

Understanding ISO/IEC 15408: The Common Criteria

ISO/IEC 15408, universally recognized as the Common Criteria (CC), is the international standard for computer security certification. It provides a framework for evaluating the security properties of Information Technology (IT) products and systems. By establishing a common language and a rigorous methodology for security evaluation, ISO/IEC 15408 ensures that the security claims made by vendors are independently verified and consistent across the global market.

1. ISO Store (Paid)

The official source. You can purchase a downloadable PDF for each part. Prices vary (approx. 150 CHF per part). This is for organizations needing legal compliance.

Step 2: Select an Accredited Lab

You cannot self-certify. You must hire a lab accredited under the CCRA (e.g., in the US: Leidos, Booz Allen; in Europe: TÜV, SGS). The lab will use ISO/IEC 18045 (the methodology PDF) to plan the evaluation.

Evaluation Process

1. Developer produces TOE and Security Target.
2. Evaluation lab assesses the TOE against the ST and applicable PPs and EAL requirements.
3. The lab issues an evaluation technical report; national schemes or certification bodies review and certify results.
4. Certifications may be recognized across countries via mutual recognition arrangements (e.g., the Common Criteria Recognition Arrangement — CCRA).
