Description
The ScoreBoardfile directive sets a file path which the server will use for Inter-Process Communication (IPC) among the Apache processes. If the directive is specified, then Apache will use the configured file for the inter-process communication. Therefore if it is specified it needs to be located in a secure directory. If the ScoreBoardfile is placed in a writable directory, other accounts could create a denial of service attack and prevent the server from starting by creating a file with the same name, and or users could monitor and disrupt the communication between the processes by reading and writing to the file.

Check Text ( C-33778r2_chk )
To determine the location of the file enter the following command: find / -name ScoreBoard. To view the permissions on the file enter the following command: ls -lL /path/of/ScoreBoard. If the permissions on the file are not set to 644 or is configured to be less restrictive, this is a finding.
