Solution

If a nosec tag is:

• the prefix of the comment (group)
• or the prefix of a line in the multi-line comment (group), where the whitespaces in this line before nosec are ignored.

then nosec will work.

For example:

//#nosec

// #nosec

//#nosec G101

// #nosec G101

// Some description
// #nosec

//#nosec -- justification

//#nosec
//-- justification

//#nosec
//G101 G102

Examples that #nosec will not work:

//Some description #nosec

// Some description #nosec
// Another description

Bad practices:

// G101
//#nosec
ViolateG102() // This violation will not be reported since "G101" before "#nosec" is discarded.

//#nosec G101
//#nosec
ViolateG102() // This violation will be reported since only G101 is suppressed here.

//#nosec
//This description will not be tracked as a justification of this suppression.
Violate()
