ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。
Credential Management
Abstract
ユーザー名を平文で保管するとシステムが危険にさらされる結果を招くことがあります。
Explanation
Credential Management の問題が発生するのは、アプリケーションの設定ファイルやデータベースにユーザー名が平文で保管されることが許可される場合です。
例 1: 次のコードは Web フォームからユーザー名を読み取り、そのユーザー名を使用してデータベースに接続しています。
このコードは正常に動作しますが、テーブル
例 1: 次のコードは Web フォームからユーザー名を読み取り、そのユーザー名を使用してデータベースに接続しています。
<cfquery name = "GetCredentials" dataSource = "master">
SELECT Username, Password
FROM Credentials
WHERE DataSource="users"
</cfquery>
...
<cfquery name = "GetSSNs" dataSource = "users"
username = "#Username#" password = "#Password#">
SELECT SSN
FROM Users
</cfquery>
...
このコードは正常に動作しますが、テーブル
master
にアクセスできる全員が Username
と Password
の値を読み取ることができます。不心得な従業員がこの情報へのアクセス権を持っている場合、システムに侵入するために使用されることがあります。References
