Use the glide.sm.default_mode property to control the default
behavior of security manager when it finds that existing ACL rules are a part of wildcard table
ACL rules.
When the High Security Settings (
com.glide.high_security) plugin is
activated during initial instance installation, it creates this property, and wildcard ACL
rules come into existence. To provide role-based access to system tables, these rules
control a significant number of ACLs and most common record-based operations:
Unless you use the High Security plugin with default deny option enabled, many tables are
not protected. The Now Platform uses a default deny security model that prevents
non-administrator users from accessing objects unless they meet a matching ACL rule. Using
this model, it removes many attack vectors, such as insecure scripts.
