今日のネットワーク化された世界において、データの保護はこれまで以上に重要になっています。特に環境、産業、科学的なモニタリングにおいてはなおさらです。Campbell Scientificの自動モニタリングプラットフォーム(データ収集システムまたはデータロガーとも呼ばれます)をご利用の場合、強力なセキュリティ対策によってシステム自体だけでなく、信頼するデータの整合性も保護されます。 このブログ記事とシリーズの次の 2 つの記事では、自動監視プラットフォームを安全に保つために実行できる実用的な手順を紹介します。 ハードウェアを保護する まずは基本から、ハードウェアの保護から始めましょう。 不正アクセスを防ぐために、自動監視プラットフォーム、電源、周辺機器を安全な場所に配置します。 ケーブルとインターフェースを干渉や改ざんから保護します。 内蔵の 3 段階セキュリティ システムを使用します。 安全な通信のためにPakBus ®暗号化キーを設定します。 3段階のセキュリティを設定する方法 Campbell Scientificの自動監視プラットフォームは、最大3段階のセキュリティコード(セキュリティレベル1、2、3)をサポートし、さまざまなシステム機能へのアクセスを制御します。有効なセキュリティコードは1~65535の整数です(0 = セキュリティなし)。 セキュリティ設定にアクセスします: LoggerNet Connect 画面、デバイス構成ユーティリティ (DevConfig)、またはターミナル エミュレータを使用して、自動監視プラットフォームに接続します。 DevConfig の [Security] または [Deployment] → [Datalogge] タブ (または LoggerNet の同等のメニュー) に移動します。 各セキュリティ レベルを構成します: キュリティレベル1(最高権限) – プログラムや設定の変更を含むフルアクセスを許可します セキュリティレベル2(中程度の権限) – 一部の変更(例:時計、パブリックテーブル変数)は許可されますが、プログラム全体の変更は制限されます。 セキュリティ レベル 3 (最低の権限) – データ収集のみが許可され、上位レベルのコードが入力されない限り、その他の通信/アクションはブロックされます。 構成されたセキュリティ レベルごとに次のようになります: 数値のセキュリティ コード... 続きを読む著者: Dana Worley | 最終更新日: 04/09/2021 | コメント: 0
