A.8.29 Security testing in development and acceptance mostly match
detects

Security testing in development catches LDAP injection via dynamic analysis or fuzzing, but does not prevent it at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and query construction practices that directly prevent LDAP injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include explicit rules for safe construction of directory queries, mitigating LDAP injection.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of LDAP special characters, directly eliminating this weakness.

A.8.27 Secure system architecture and engineering principles none match
none

Secure architecture principles encourage safe query interfaces but do not prescribe the specific coding controls needed for LDAP injection.

A.8.3 Information access restriction none match
none

Information access restriction limits who can query LDAP but does not address how queries are built.
