Each year technology companies sunset both hardware and software 版本. 有些人会说这是计划废弃，但不管怎样, most organizations will be impacted as more common software and hardware is retired by the manufacturer.

As an owner or user of these products often you will receive emails or see messages appear as you launch or use these products alerting you to version and or support expiration. In many cases, these 警报 are a way to advertise a new version of a product, new features, 等. While these 警报 can seem benign and even annoying, if ignored, they can create 风险和脆弱性 对于你的组织来说.

第一步是理解警报的真正含义. 技术 companies normally define the retirement of a version /model in three categories, 销售结束, 生命的终结, 或终止支持.

什么是制造商销售终止?

销售结束 simply means the manufacturer (OEM) is no longer actively selling the item however this does not mean you will not or cannot find these items. 举个例子, Cisco may stop selling a wireless access point but when searching (Google, Bing) you may find many options to purchase the item from other non-approved sources).

什么是技术生命终结(EOL)?

生命周期结束(EOL)是用来描述产品的使用寿命. After this period, the manufacturer will stop marketing, selling, or updating that particular item. 生命的终结 indicates that the manufacturer will soon replace your equipment with a newer generation of the product. So, 此时此刻, 您的OEM停止生产当前产品, 这样就造成了硬件的稀缺. Doing this will cause a significant boost in demand for the newer generation product when launched. 当您的设备进入EOL生产阶段时, your OEM may still offer you maintenance services for your hardware/software even after the End-of-Life phase has long passed. 然而，这需要付出高昂的代价.

生命终止(EOL)和支持终止(EOS)有什么区别??

End of Support (EOS) for a product is also often referred to as the End of Service Life (EOSL) of a product. 它是硬件/软件生命周期的最后阶段. This term is used to point out that your equipment /software’s OEM is planning to bring a complete end to the existence of your hardware/software version. It goes beyond OEM not selling or manufacturing already out of stock hardware /software, but they will also terminate the maintenance services they were providing before, 从而使您的设备无法操作. 此时此刻, 在某些情况下, 您将被转介给第三方服务提供商, 当然, 还能给你所需的所有快速支持吗, 但你的OEM将不再对此负责. 一旦OEM决定停止支持某个产品，它就会发布一个 使用寿命终止清单. This data informs the public about the development and also the rise of a newer generation product. 为软件, 制造商可以提供扩展支持选项, 但这些可能有一定的限制，包括时间, 更新类型, 等.

Adobe Flash终止支持(EOS)

In 2020 and 2021 there are several common software applications that have been retired and therefore may impact your organization. We will focus on two, Adobe Flash Player and 微软 Teams using Internet Explorer 11.

大多数组织已经使用Adobe Flash播放器很多年了. In many cases, Flash Player is installed when a computer is purchased from the manufacturer. Flash was developed to provide access to multi-media, rich web content, 等.

Adobe began a communication campaign in 2017 to retire Flash due to ongoing performance impacts and security vulnerabilities. While most software manufacturers have been remediating their products to address the retirement of Flash be aware that some custom and commercial applications may not have been updated.

以下是来自Adobe的最新通信. 请注意，Flash内容将在2021年1月12日被屏蔽. It is critical that you test your software applications to confirm they will continue to work without Flash.

由于Adobe在12月31日不再支持Flash Player, 2020, and Adobe will block Flash content from running in Flash Player beginning January 12, 2021, Adobe strongly recommends all users immediately uninstall Flash Player to help protect their systems. 

  • 由于Adobe在EOL日期之后不再支持Flash Player, Adobe will block Flash content from running in Flash Player beginning January 12, 2021年，帮助确保用户系统的安全. Flash Player may remain on the user’s system unless the user uninstalls it.
  • 截至2020年12月31日，微软通过Windows更新删除了Flash.
  • 谷歌Chrome强制所有Flash内容在使用前必须经过审核.

 

微软 Teams EOS for Internet Explorer Version 11

Many of us are also using 微软 Teams to collaborate with our co-workers and clients. Teams can be accessed and used from a web browser or via a dedicated client developed for specific hardware platforms like Windows, Mac OS, IOS, 和安卓. 

  • 截至11月30日, 2020, 微软, 已停止支持使用ie11访问Teams. 
  • 此外, 8月17日, 2021, 微软 will end support for Office 365 Web applications such as Outlook Web Access via Internet Explorer version 11. 

采用像微软 Edge这样的新浏览器版本是很重要的, 谷歌Chrome, 或Mozilla Firefox. 

降低生命终结技术的风险

这只是众多受到影响的软件中的两款. 为了降低与生命终结技术相关的风险. Below are a few tips for reducing end of life technology vulnerabilities.

  • Scan your IT infrastructure for end of life technologies –  pay attention to emails, 警报, 以及显示要支持的更改的屏幕, 版本, 以及确保您的组织不受影响的功能.
