보안 테스트

Blackboard에서는 Blackboard와 고객의 기대치를 모두 충족시키기 위해 코드 수준(정적 분석) 및 애플리케이션 수준(동적 분석)에서 지속적인 내부 보안 테스트를 수행합니다. 그뿐만 아니라 주기적으로 애플리케이션을 새로운 시각으로 판단하기 위해 Blackboard는 타사 보안 벤더의 보안 침투 테스트를 실시합니다. 확인된 모든 문제는 수리 일정이 빠르게 정해집니다.

정적 애플리케이션 보안 테스트

Blackboard에서는 오픈 소스 및 상업용 정적 분석 스캐너를 활용하여 Blackboard Learn의 소스 코드를 지속적으로 평가합니다. 또한 시스템이 빌드 환경과 통합되어 발전할 때 이러한 도구를 통해 소스 코드의 잠재적인 취약점을 확인할 수 있으며, 보안 취약점에 대한 자동화된 소스 코드 분석을 수동 코드 검토와 결합합니다.

동적 애플리케이션 보안 테스트

Blackboard에서는 오픈 소스 및 상업용 동적 분석 스캐너를 활용하여 Blackboard Learn 애플리케이션을 지속적으로 평가합니다. 자동화된 보안 스캐너는 최종 사용자의 관점에서 일반적인 웹 애플리케이션의 취약점을 테스트합니다.

수동 침투 테스트

정적 및 동적 애플리케이션 보안 도구가 모든 보안 문제를 감지할 수는 없습니다. Blackboard에서는 보안 위험을 더 완화하기 위해 수동 침투 테스트를 수행하여 보다 복잡한 보안 취약점 및 부적절한 권한 부여와 같은 비즈니스 논리 문제를 확인합니다.

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.
