New in SWEHB

The subjects include: 

• A. Software Assurance Planning
• B. Software Assurance Analysis
• C. Software Assurance Static Analysis Tools
• D. Software Assurance Audits
• E. Software Assurance Communications
• F. Software Assurance Product Reviews

This topic is designed to provide a basic knowledge of the implementation and importance of good software assurance and software safety through the use of static code analysis in support of projects and missions.

The new topics discuss considerations that must be taken into account when Artificial intelligence and Machine Learning is used in developing Software Products. 

The new PAT is an expanded checklist for exploring the complexities of the Safety-Critical or Mission-Critical software. SWE-134 has 12 areas that need to be taken into account and the checklist covers these in detail.  

Topic 7.23 - Software Fault Prevention and Tolerance This topic guides developers to reduce the likelihood of software faults pre-flight and to detect/mitigate the effects of software errors should they occur in-flight.  

Changes include: 

1. Reformatted tabs with new tables for "Entrance Criteria", ""Items Reviewed", and Exit / Success Criteria. 
2. Old content moved to expandable sections under "Additional Supporting Material" at the bottom of each tab. 

Changes include: 

1. Added the PPS code in the legend allows for the columns in both tables to be the same size. The headings are "Sticky" so that stay at the top of the visible page as the reader scrolls down. 
2. Added links in both tables to the "Minimum Content" Topic pages, where they exist. 

This topic includes a table of Risks in several categories and phases. It provides guidance on the Reviews in which the risk is expected to be reviewed and mitigations discussed.

This Topic guides mission security implementation in the form of principles coupled with applicable controls that cover both the space vehicle and the ground segment. It is based on the "Space Security Best Practices Guide" released October 18, 2023. It includes, as an appendix, NASA-STD-1006 - Space System Protection Standard. 

The new tab contains links to a series of pages that contain guidance for the minimum recommended content for typical Work Products in the SWEHB. It includes pages referenced in NPR 7150.2D, Chapter 6 - Recommended Software Records Content. 

Additional pages will be added to include some that are used by Software Assurance (from Topic 8.16 - SA Products). 

The new series is posted in D. Topics page and all references to these topics in the current version of the handbook have been updated. 

The new workbook was uploaded into Topic 8.15 and is built on the documents: 

• NPR 7150.2C
• NASA-STD-8739.8A

Another update of this workbook is in process and will be based on the NPR 7150.2D and NASA-STD-8739.8B. 

Introductory remarks have been shortened by putting the content in expanding sections ("Click to see ...")

Each page has a new section below the introductory remarks. The new section contains two expanding displays of ALL SWEs. 

• First, is a list of all SWE pages in Numeric Order. Each entry is a link to the SWE page. 
• Second, is a list of all SWE pages along with the text of the requirement in numeric Order. Each SWE entry is a link to the SWE page. 

When expanded, you my use your browser's "Find" function to look for key words in the SWE titles or requirements on the browser page.  

Additionally, the link to "New in SWEHB" link has been added at the top of both Requirements pages.
