セキュリティテスト

Blackboardは、コードレベル (静的解析) およびアプリケーションレベル (動的解析) での内部セキュリティテストを継続的に実施し、Blackboardとお客様両方の期待を確実に満たすようにしています。さらに、アプリケーションを常に新しい視点で見られるように、Blackboardではサードパーティのセキュリティベンダによるセキュリティペネトレーションテストを受けています。問題が特定された場合は、ただちに修正が予定されます。

静的アプリケーションセキュリティテスト

Blackboardはオープンソースと商業向け静的分析スキャナを活用し、Blackboard Learnソースコードを継続的に評価しています。これらのツールにより、Blackboardは、システムが構築環境との統合を通じて発展していく中で、ソースコードの潜在的な脆弱性を特定できます。Blackboardは、セキュリティの脆弱性に対する自動化されたソースコード分析と手動によるコードレビューを組み合わせています。

動的アプリケーションセキュリティテスト

Blackboardはオープンソースと商用の動的分析スキャナを活用し、Blackboard Learnアプリケーションを継続的に評価しています。自動化されたセキュリティスキャナは、エンドユーザの観点から一般的なWebアプリケーションの脆弱性をテストします。

手動によるペネトレーションテスト

静的および動的アプリケーションセキュリティツールではすべてのセキュリティ問題を検知できません。セキュリティリスクをさらに軽減するために、Blackboardは手動によるペネトレーションテストを実施し、より複雑なセキュリティの脆弱性と不適切な承認などのビジネスロジックの問題を特定します。

Security patches and advisories

Blackboard publishes security patches and advisories through Behind the Blackboard.

BbPatch

Customers may install the latest patches using "BbPatch," a package management utility to manage updates to Blackboard products, such as cumulative patches. BbPatch complements the Blackboard Installer by allowing small, reversible updates with minimal downtime.

Software updates

The Software Updates module is located in the Blackboard Learn Administrator Panel and provides updates specific to your Blackboard Learn installation, including Major Releases, Service Packs, and Patch Sets, as well as building block updates and newly released building blocks. The module lists the number of updates that are available. You can select which updates to download.

Security advisories

Blackboard is committed to the timely identification, communication and resolution of security vulnerabilities identified in our products. Security Advisories are released with the following information:
  • Advisory ID - for Knowledge Base tracking purposes
  • Title - Brief description of affected area
  • Issue Date
  • Severity
This is followed by a vulnerability overview, which details the nature of the security vulnerability; a functional issue overview which describes how the system may be affected; a list of product version(s) affected; description of discovery; and a description of the solution with a link to applicable patches. Blackboard also tracks and advises our clients of any known exploitation or malicious use of security vulnerabilities. The mitigations and workarounds section describes any mitigations clients may take or if a workaround is available. If there are multiple revisions to an advisory, a short summary of the update is provided.

Security vulnerability scoring

Blackboard follows the industry standard of CVSSv2 (Common Vulnerability Scoring System Version 2.0) as a guideline. Customers may use our severity ratings as a guideline to help classify the impact of security issues found in Blackboard Learn. It is based on average usage, since not all vulnerabilities have equal impact on all users - for example, customers might not have the affected module enabled, or its use of the module may not contain as critical information as another customer.

Input Validation Filter - Security management building block

The Input Validation Filter acts as a first line of defense with configurable rules to protect Blackboard Learn. It is, in a sense, like a firewall for Blackboard Learn. It verifies that user requests coming in are safe by sanitizing the data through a default ruleset. An advantage of the Input Validation Filter is speed. This feature provides you with cross-site scripting fixes much faster than the traditional patching process. Traditional patches can have various dependency issues or may need to be rolled back. Providing fixes through the Input Validation Filter is a much cleaner and faster way of delivering patches, as they are provided directly through the Software Updates Center.
