我们为什么需要 HENNGE Email DLP?

HENNGE Email DLP 是 HENNGE 提供的一套完整的电子邮件安全系统,它的作用在于预防内部的人为疏失倒置讯息安全漏洞。HENNGE Email DLP 的功能包含电子邮件扣留防止资料外泄寄件审核自动密码加密等等。这些特色都可以确保公司传出去的邮件都是经过程式判断并为审核的严密检查。不只公司和外部人员的沟通是严密的,机密的公司资料也不会被盗取。 

1) 电子邮件扣留 

暂时扣留寄出的电子邮件,扣留的时间可以由企业自行条整。扣留电子邮件主要的目的在于让寄件者能够确认寄出的信件中是否有误。若有重大错误时,寄件者可以在扣留的时间内回收信件。

  • 自由设定条件:系统管理员可以自行设定扣留条件与规则。 
  • 预设扣押规则:系统已经预设了几条扣押信件的规则。例如每封邮件都预设被扣留五分钟不论内容。
  • 扣押邮件:当用户按下了传送电子邮件的按钮之后,信件会暂时在 Email DLP User Console 下面等待。用户在时间范围内还可以决定寄出、删除,可是时间一到,信件仍然会被自动送出。
  • 搜寻扣留历史:最近100封被扣留的电子邮件可以在此被列出来。
  • Suspension Notification - The admin could configure the system to send a notification email to remind the mail sender that the sent mail is being suspended.

2) 防止资料外泄 

设定筛选条件过滤机密的讯息资料包含信用卡密码、电话号码、特殊关键字和电子邮件等。

  • Mail Group - A Mail Group consists of a list of specific email addresses that can be used to assigned to a specific filter
  • Rule Group - A Rule Group consists of one or more rules that can be used to assigned to a specific filter
  • Rule - A Rule has multiple elements such as Action, Notification and Rule Condition
  • Action - An Action is the system's response if the sent mails meet the Rule Condition defined. The Action can be to Send the email, to Discard the email, to Request for Approval to send the email or to Suspense the email Temporarily.
  • Notification - A Notification mail is to be sent to an individual if the sent mails meet the Rule Condition defined. The Rule can be configured to send Notification mail to Sender, ApproverAdministrator, any two of them, all of them or none of them.
  • Rule Condition - A Rule Condition can be configured to allow the Rule to apply to "Match all messages", "Match all the following (AND)", "Match any of the following (OR)" and "Match messages that cannot be analysed". For "AND" and "OR", specific rule can be configured to scan for potential confidential data such as credit card no., specific keyword, and regular expression to ensure that the email is suspended or discarded.
  • Filter - A Filter consists of elements such as Priority, Sender, Recipient, and Rule Group
  • Sender and Recipient - A specific Mail Group shall be assigned to both Sender and Recipient or if it is not applicable to select a specific Mail Group, "All" can be assigned to include mails from all email address.

可以设定特别条件特定的寄件者或包含特定文字等机密资料的电子件必须通过审核者审核才能被传送。

  • 审核者:审核者可以审查并确定该封滞留的电子邮件的内容为安全的并符合公司保密制度方可被寄出。
  • 待审核信件:如果一封电子邮件符合了某项筛选条件并需要审核者的审核,该封信件则可以被审核者查阅。

4) 自动密码加密 

- 用户可以安全的传送压缩成加密的附件档案。

  • 自动压缩:如果寄件者附加了一个附件档案,档案会被自动压缩成一个ZIP档案。节省寄件资源和防止特定扩展名遭到封锁。
  • 自动加密:收件者在传送有附件的邮件时,系统会自动把电子邮件的附件加密并传送包含密码的第二封电子邮件给收件者。
  • 可客制化:管理员可以设定只对特定的群组加密附件,也可以要求附件密码传送给寄件者而不是收件者。
