Check Text ( C-17780r1_chk )
If the application does not contain sensitive or classified information this check does not apply. If the application is a COTS/GOTS product or is composed of only COTS/GOTS products with no custom code, this check does not apply unless the application is being reviewed by or in conjunction with the COTS/GOTS vendor in which case this check is applicable.. Ask the application representative to review global variables for the application. If the global variables contain sensitive information, ask the application representative if they are required to be encrypted by the data owner. If the data is required to be encrypted by the data owner, ask the application representative to demonstrate they are encrypted. Note: The .Net Framework 2.0 and higher provides a SecureString class which can encrypt sensitive string values. 1) If sensitive or classified information is required to be encrypted by the data owner and global variables containing sensitive information are not encrypted, it is a finding.
