Application Examples
 Developed over eight years by more than 30 developers
 At least twelve APEX themes in use
 Examples…
7
The Problem
 Variation
 Twelve different themes
 Duplication of effort
 User access maintenance
 Other functions
 Lack of internal application security
 No Authorization Schemes (security through obscurity)
 Page Access Protection not enabled (URL tampering)
 Report columns not escaping special characters (XSS)
 Inappropriate use of &ITEM. syntax (SQL injection)

a3_log_debug( ‘Debug’, v_group_id );
a3_log_error( ‘Error’, v_group_id );
a3_log_warning( ‘Warning’, v_group_id );
 Debug message only generated if debugging switched on in APEX
or a3_log_pkg.gv_debug is TRUE
24
Configuration Export & Import
 Configuration Export, by
 Object type or specific object
 Grouping of objects by change date
 Entire application
 Configuration Import
25
Dropdown Menu

 Integral for seamlessly adding shared pages
26
Dropdown Menu Technical
 Started with a Plugin from http://www.apex-plugin.com/
 Moved PL/SQL to shared schema

Shared Pages
 Original plan was to include a set of administration pages in the
standard application template
 Foundations
 Consistent theme
 Consistent variable naming
 Shared security framework
 Drop-down menu
 Captures session state prior to accessing shared page
 Shared application adopts security and session state of calling
application
32
APEX Portal
 Home page for users listing the applications they have access to
 Centralized reporting
 Place for users to request further access
33
Security Assurance
 Report checks application is set up correctly
 Checks compliance to the security standards
 Authorization Scheme for entire application
 Page Access Protection on
 Report fields restrict HTML characters
 &ITEM. Syntax not used in SQL queries
 Checks page relationships
34
APEX Base Tables
 Tables available in the APEX_040000 schema (version 4.0)
 Don’t alter these tables, or you’ll void your support
