Exchange Server 2016 online training courses now available

Microsoft announced the release of four new edX online training courses for Microsoft Exchange Server 2016. If you plan to implement Exchange Server 2016 or Exchange Online, or if you want to make sure that your implementation was done right, the Exchange Server 2016 online training courses are for you.

Course offerings include:

Each Exchange course is targeted to the IT professional audience, with hands-on labs that reinforce student learning. Students are graded on completing each module, as well as on module assessment exams and a final course exam. A Certificate can be earned by completing each course with a passing grade. Courses are self-paced, allowing IT professionals to build Exchange skills at their own pace as their schedules permit.

The first course, CLD208.1x: Microsoft Exchange Server 2016 Infrastructure, is free. The remaining three courses are for-fee courses at $49 USD per course.

edX is a massive open online course (MOOC) provider that was developed by MIT and Harvard University. The Microsoft Learning Experiences team has created a wide range of online training courses for edX, and these four Exchange courses are the team’s latest Office releases. They are the first of seven courses that cover the core skills an Exchange administrator needs to proficiently design, implement and manage an Exchange 2016 and Exchange Online implementation.

CPU usage is high when you use RPC over HTTP protocol in Windows 8.1 or Windows Server 2012 R2

Consider the following scenario that takes Microsoft Exchange Server 2013 as an example:

  • The Mailbox server role is enabled in Exchange Server 2013.
  • Exchange mailboxes use extended MAPI to communicate with the Exchange Server.
  • The extended MAPI uses Microsoft RPC over HTTP (remote procedure call over HTTP) protocol.
  • Many clients (such as mobile devices) are dropping connections to the Exchange Server.

In this scenario, the CPU usage on the Exchange server may reach 100 percent.\

Security Bulletin: iOS “Pegasus” Malware and iOS 9.3.5 Security Update

On Aug. 25, 2016,  Apple announced updates to address security vulnerabilities in iOS version 9.3.4 and earlier. The affected components include the iOS kernel and WebKit.

The vulnerabilities can result in jailbreak, remote code execution, and memory corruption.  Security researchers at Lookout, Inc. have identified a high risk malware application, called “Pegasus”, that uses the vulnerabilities to compromise user devices.

MobileIron recommends that users update to iOS version 9.3.5 or later to obtain the necessary security patches. The security researchers have confirmed that the iOS patches prevent the vulnerabilities from being exploited.

Three vulnerabilities were patched in iOS 9.3.5.  The vulnerabilities are referred to collectively as “Trident”.  The reported CVE identifiers include:

  • CVE-2016-4655: An application may be able to disclose kernel memory.
  • CVE-2016-4656: An application may be able to execute arbitrary code with kernel privileges.
  • CVE-2016-4657: Visiting a maliciously crafted website may lead to arbitrary code execution.

Detection of Pegasus Jailbreak:

According to the security researchers at Lookout, EMM vendors cannot currently detect the Pegasus jailbreak. At this time, the only known method to detect Pegasus is to use products from Lookout.
