## 6 Comparison of the BSI and NIST Guides  
This section compares the two guides to each other, using the depth and completeness scores. The guides differ a lot from each other, thus it is not surprising that the values of scores are very different as well. Table 8 shows the results of both guides in comparison using following columns: A = BSI completeness, B = NIST completeness, C = Completeness difference (B\(-\)A), D = BSI depth, E = NIST depth, F = Depth difference (E\(-\)D). Columns C and F show the difference between the two guides for completeness (C) and depth (F). The difference is calculated by subtracting the value of the score of the BSI guide from the value of the NIST guide. Thus a positive value in these columns stands for a higher value for NIST, and a negative value represents a higher value of the BSI guide. On average the completeness of the NIST guide is 0.41 higher than the completeness of the BSI guide. When looking at the totals, the difference is even higher. 0.51 is the total difference in completeness \begin{table}

Table 8: Comparison of BSI and NIST. Columns: A = BSI completeness; B = NIST completeness; C = Completeness difference (B\(-\)A); D = BSI depth; E = NIST depth; F = Depth difference (E\(-\)D). based on the total counts of relevant RFCs and covered RFCs. This means that the NIST guide covers 41% more RFCs on average and even 51% in total. There is only one occurrence of a negative value (BSI \(>\) NIST). This is the subcategory _Routing Protocols_. Here the BSI guide covers all of the relevant RFCs, while the NIST guide covers 80% (4 out of 5). Both guides have equal completeness values in three subcategories. Both completely covered the subcategories _Path MTU Discovery_ and _Stateless Autoconfiguration_. They also have the same value (0.33) in the subcategory _DNS Specification_ where both covered the main RFC for DNS for IPV6, but ignored the other two relevant RFCs. In all other subcategories and all main categories, the NIST guide is superior to the BSI guide in terms of completeness.
