Jul 12, 2018  If Device Encryption isn’t enabled—or if you want a more powerful encryption solution that can also encrypt removable USB drives, for example—you’ll want to use BitLocker. Microsoft’s BitLocker encryption tool has been part of Windows for several versions now, and it’s generally well regarded. To access a BitLocker drive on Mac OS X, you have to firstly connect the drive to a Windows computer and then simply go to Control Panel System and Security BitLocker Drive Encryption to turn off BitLocker encryption on this drive. If you cannot find any Windows machine, you have to use a third-party utility to access the BitLocker drive on Mac OS X.

When you store sensitive data on your computer, it’s crucial that you take the necessary steps to protect that data. You can protect your data by using encryption.

Unlike a physical Windows PC, Windows virtual machines afford more encryption options, as there is the macOS® host operating system and Parallels Desktop® for Mac virtualization.

Enterprise environment encryption is a standard and a must. Most of the time, IT teams use BitLocker, which is available in Pro and Enterprise editions of Windows 7 and Windows 10.

In this article, we will compare virtual machine encryption: Microsoft BitLocker encryption to Parallels Desktop for Mac encryption engine.

Special aspects of virtualization for encryption

BitLocker normally requires a Trusted Platform Module, or TPM, on your computer’s motherboard. This is a special microchip that enables a device to support advanced security features.

Since we are talking about virtual machines running on Mac®, this is not an option; Mac computers do not have a TPM chip. You can use BitLocker without a TPM chip by using software-based encryption, but it requires some extra steps for additional authentication.

On the other hand, Parallels provides an encryption module. This module uses Advanced Encryption Standard (AES) with 256-bit key length, which is sufficiently strong and has a fast encryption algorithm.

Disk Performance

If you are considering BitLocker encryption for your Parallels Desktop virtual machines, make sure you are using Windows 10. With Windows 10, Microsoft introduced an ability to “Encrypt used disk space only (faster and best for new PCs and drives).” If you enable BitLocker in Windows 7 that has expanding virtual hard disks by default, all its free virtual hard disk space will be allocated. (If it was 18 GB, it will likely become 64 GB or 128 GB. It depends on what was the maximum allowed size of expanding virtual hard disk. An expanding virtual hard disk image file is small initially. Its size grows as you add applications and data to the virtual hard disk in the guest OS.)

We ran some performance tests on a Windows 10 virtual machine for BitLocker and Parallels encryption:

• BitLocker is faster than Parallels encryption when working with large files.

BitLocker seems to be faster, especially if you work with large files up to 2 GB, where the difference can be up to two times faster. With average office work it is not that dramatic—BitLocker is only about 7% faster.

• Enabling BitLocker slows down virtual machines by 10% compared to non-enabled machines.

If we compare a virtual machine with and without BitLocker enabled, the VM without BitLocker is about 10% faster in disk operations. BitLocker should also affect battery life a little, but this is the cost you pay for data security.

Configuration used in testing:

Parallels Desktop 12 for Mac, build 12.2.0-41591

Mac Pro® “Quad Core” 3.7 (Late 2013)

macOS 10.12.4

Windows 10 2vCPU and 2 GB vRAM

BitLocker and Parallels Encryption Engine Limitations

If a BitLocker-enabled virtual machine is in suspended state, or there is a snapshot of a running state created, then this virtual machine becomes vulnerable to unauthorized access to data which is not the case with Parallels encryption engine.

As a preventive workaround for this potential security breech when using BitLocker with a virtual machine, the virtual machine must be always shut down after a user has finished his work with it. There is a way to make it easier with Parallels virtual machine settings by changing both options “On Mac Shutdown” and “On Window Close” values to “Shut Down”.

The current Office for Mac; Office 365 or Office 2019 are OK with Catalina. What’s in it? Apple has their list of Catalina changes here. Two changes stand out for us. One is a major change in the way audio/video entertainment is managed. The other is great for Microsoft Office users, thought it’s not available to everyone. ITunes is gone. Microsoft office 2019 compatible with mac 2011 torrent. With the release of macOS 10.15 Catalina,Office 365 for Mac and Office 2019 for Mac support macOS 10.15, 10.14, and 10.13. Moving forward, as new major versions of macOS are made generally available, Microsoft will drop support for the oldest version and support the newest and previous two versions of macOS. Mar 19, 2020  Upgrading Office 2011 to Office 2019 for Mac won't have any influence on your current Workbooks, documents or Presentations. You could work on them via Office 2019 as well. Meanwhile, Office 2011 and Office 2019 can be installed at the same time on a Mac, if you have strong concern on this, you can first install Office 2019 on your Mac, check the outcome before uninstalling your Office 2011.

Parallels encryption engine does not support the use of USB flash drives to get authorized access to BitLocker-encrypted drives, but it might have been already fixed by the time you read this post. If not, and you are interested in this functionality, let us know on our dedicated forum thread for feature suggestions.

We think that data protection is important and you learned something new after reading this article.

This topic explains how BitLocker Device Encryption can help protect data on devices running Windows 10.For a general overview and list of topics about BitLocker, see BitLocker.

When users travel, their organization’s confidential data goes with them. Wherever confidential data is stored, it must be protected against unauthorized access. Windows has a long history of providing at-rest data-protection solutions that guard against nefarious attackers, beginning with the Encrypting File System in the Windows 2000 operating system. More recently, BitLocker has provided encryption for full drives and portable drives. Windows consistently improves data protection by improving existing options and by providing new strategies.

Table 2 lists specific data-protection concerns and how they are addressed in Windows 10 and Windows 7.

Prepare for drive and file encryption

The best type of security measures are transparent to the user during implementation and use. Every time there is a possible delay or difficulty because of a security feature, there is strong likelihood that users will try to bypass security. This situation is especially true for data protection, and that’s a scenario that organizations need to avoid.Whether you’re planning to encrypt entire volumes, removable devices, or individual files, Windows 10 meets your needs by providing streamlined, usable solutions. In fact, you can take several steps in advance to prepare for data encryption and make the deployment quick and smooth.

TPM pre-provisioning

In Windows 7, preparing the TPM for use offered a couple of challenges:

• You can turn on the TPM in the BIOS, which requires someone to either go into the BIOS settings to turn it on or to install a driver to turn it on from within Windows.
• When you enable the TPM, it may require one or more restarts.

Basically, it was a big hassle. If IT staff were provisioning new PCs, they could handle all of this, but if you wanted to add BitLocker to devices that were already in users’ hands, those users would have struggled with the technical challenges and would either call IT for support or simply leave BitLocker disabled.

Microsoft includes instrumentation in Windows 10 that enables the operating system to fully manage the TPM. There is no need to go into the BIOS, and all scenarios that required a restart have been eliminated.

Deploy hard drive encryption

BitLocker is capable of encrypting entire hard drives, including both system and data drives. BitLocker pre-provisioning can drastically reduce the time required to provision new PCs with BitLocker enabled. With Windows 10, administrators can turn on BitLocker and the TPM from within the Windows Preinstallation Environment before they install Windows or as part of an automated deployment task sequence without any user interaction. Combined with Used Disk Space Only encryption and a mostly empty drive (because Windows is not yet installed), it takes only a few seconds to enable BitLocker.With earlier versions of Windows, administrators had to enable BitLocker after Windows had been installed. Although this process could be automated, BitLocker would need to encrypt the entire drive, a process that could take anywhere from several hours to more than a day depending on drive size and performance, which significantly delayed deployment. Microsoft has improved this process through multiple features in Windows 10.

BitLocker Device Encryption

Beginning in Windows 8.1, Windows automatically enables BitLocker Device Encryption on devices that support Modern Standby. With Windows 10, Microsoft offers BitLocker Device Encryption support on a much broader range of devices, including those that are Modern Standby, and devices that run Windows 10 Home edition.

Microsoft expects that most devices in the future will pass the testing requirements, which makes BitLocker Device Encryption pervasive across modern Windows devices. BitLocker Device Encryption further protects the system by transparently implementing device-wide data encryption.

Unlike a standard BitLocker implementation, BitLocker Device Encryption is enabled automatically so that the device is always protected. The following list outlines how this happens:

Wipe A Bitlocker Encrypted Drive

• When a clean installation of Windows 10 is completed and the out-of-box experience is finished, the computer is prepared for first use. As part of this preparation, BitLocker Device Encryption is initialized on the operating system drive and fixed data drives on the computer with a clear key (this is the equivalent of standard BitLocker suspended state). In this state, the drive is shown with a warning icon in Windows Explorer. The yellow warning icon is removed after the TPM protector is created and the recovery key is backed up, as explained in the following bullet points.
• If the device is not domain joined, a Microsoft account that has been granted administrative privileges on the device is required. When the administrator uses a Microsoft account to sign in, the clear key is removed, a recovery key is uploaded to the online Microsoft account, and a TPM protector is created. Should a device require the recovery key, the user will be guided to use an alternate device and navigate to a recovery key access URL to retrieve the recovery key by using his or her Microsoft account credentials.
• If the user uses a domain account to sign in, the clear key is not removed until the user joins the device to a domain and the recovery key is successfully backed up to Active Directory Domain Services (AD DS). You must enable the Computer ConfigurationAdministrative TemplatesWindows ComponentsBitLocker Drive EncryptionOperating System Drives Group Policy setting, and select the Do not enable BitLocker until recovery information is stored in AD DS for operating system drives option. With this configuration, the recovery password is created automatically when the computer joins the domain, and then the recovery key is backed up to AD DS, the TPM protector is created, and the clear key is removed.
• Similar to signing in with a domain account, the clear key is removed when the user logs on to an Azure AD account on the device. As described in the bullet point above, the recovery password is created automatically when the user authenticates to Azure AD. Then, the recovery key is backed up to Azure AD, the TPM protector is created, and the clear key is removed.

Microsoft recommends that BitLocker Device Encryption be enabled on any systems that support it, but the automatic BitLocker Device Encryption process can be prevented by changing the following registry setting:

• Subkey: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlBitLocker
• Value: PreventDeviceEncryption equal to True (1)
• Type: REG_DWORD

Administrators can manage domain-joined devices that have BitLocker Device Encryption enabled through Microsoft BitLocker Administration and Monitoring (MBAM). In this case, BitLocker Device Encryption automatically makes additional BitLocker options available. No conversion or encryption is required, and MBAM can manage the full BitLocker policy set if any configuration changes are required.

Used Disk Space Only encryption

BitLocker in earlier Windows versions could take a long time to encrypt a drive, because it encrypted every byte on the volume (including parts that did not have data). That is still the most secure way to encrypt a drive, especially if a drive has previously contained confidential data that has since been moved or deleted. In that case, traces of the confidential data could remain on portions of the drive marked as unused.But why encrypt a new drive when you can simply encrypt the data as it is being written? To reduce encryption time, BitLocker in Windows 10 lets users choose to encrypt just their data. Depending on the amount of data on the drive, this option can reduce encryption time by more than 99 percent.Exercise caution when encrypting only used space on an existing volume on which confidential data may have already been stored in an unencrypted state, however, because those sectors can be recovered through disk-recovery tools until they are overwritten by new encrypted data. In contrast, encrypting only used space on a brand-new volume can significantly decrease deployment time without the security risk because all new data will be encrypted as it is written to the disk.

Encrypted hard drive support

SEDs have been available for years, but Microsoft couldn’t support their use with some earlier versions of Windows because the drives lacked important key management features. Microsoft worked with storage vendors to improve the hardware capabilities, and now BitLocker supports the next generation of SEDs, which are called encrypted hard drives.Encrypted hard drives provide onboard cryptographic capabilities to encrypt data on drives, which improves both drive and system performance by offloading cryptographic calculations from the PC’s processor to the drive itself and rapidly encrypting the drive by using dedicated, purpose-built hardware. If you plan to use whole-drive encryption with Windows 10, Microsoft recommends that you investigate hard drive manufacturers and models to determine whether any of their encrypted hard drives meet your security and budget requirements.For more information about encrypted hard drives, see Encrypted Hard Drive.

Preboot information protection

An effective implementation of information protection, like most security controls, considers usability as well as security. Users typically prefer a simple security experience. In fact, the more transparent a security solution becomes, the more likely users are to conform to it.It is crucial that organizations protect information on their PCs regardless of the state of the computer or the intent of users. This protection should not be cumbersome to users. One undesirable and previously commonplace situation is when the user is prompted for input during preboot, and then again during Windows logon. Challenging users for input more than once should be avoided.Windows 10 can enable a true SSO experience from the preboot environment on modern devices and in some cases even on older devices when robust information protection configurations are in place. The TPM in isolation is able to securely protect the BitLocker encryption key while it is at rest, and it can securely unlock the operating system drive. When the key is in use and thus in memory, a combination of hardware and Windows capabilities can secure the key and prevent unauthorized access through cold-boot attacks. Although other countermeasures like PIN-based unlock are available, they are not as user-friendly; depending on the devices’ configuration they may not offer additional security when it comes to key protection. For more information, see BitLocker Countermeasures.

Manage passwords and PINs

When BitLocker is enabled on a system drive and the PC has a TPM, you can choose to require that users type a PIN before BitLocker will unlock the drive. Such a PIN requirement can prevent an attacker who has physical access to a PC from even getting to the Windows logon, which makes it virtually impossible for the attacker to access or modify user data and system files.

Bitlocker Drive Mac

Requiring a PIN at startup is a useful security feature because it acts as a second authentication factor (a second “something you know”). This configuration comes with some costs, however. One of the most significant is the need to change the PIN regularly. In enterprises that used BitLocker with Windows 7 and the Windows Vista operating system, users had to contact systems administrators to update their BitLocker PIN or password. This requirement not only increased management costs but made users less willing to change their BitLocker PIN or password on a regular basis.Windows 10 users can update their BitLocker PINs and passwords themselves, without administrator credentials. Not only will this feature reduce support costs, but it could improve security, too, because it encourages users to change their PINs and passwords more often. In addition, Modern Standby devices do not require a PIN for startup: They are designed to start infrequently and have other mitigations in place that further reduce the attack surface of the system.For more information about how startup security works and the countermeasures that Windows 10 provides, see Protect BitLocker from pre-boot attacks.

Configure Network Unlock

Some organizations have location-specific data security requirements. This is most common in environments where high-value data is stored on PCs. The network environment may provide crucial data protection and enforce mandatory authentication; therefore, policy states that those PCs should not leave the building or be disconnected from the corporate network. Safeguards like physical security locks and geofencing may help enforce this policy as reactive controls. Beyond these, a proactive security control that grants data access only when the PC is connected to the corporate network is necessary.

Network Unlock enables BitLocker-protected PCs to start automatically when connected to a wired corporate network on which Windows Deployment Services runs. Anytime the PC is not connected to the corporate network, a user must type a PIN to unlock the drive (if PIN-based unlock is enabled).Network Unlock requires the following infrastructure:

Truecrypt

• Client PCs that have Unified Extensible Firmware Interface (UEFI) firmware version 2.3.1 or later, which supports Dynamic Host Configuration Protocol (DHCP)
• A server running at least Windows Server 2012 with the Windows Deployment Services role
• A server with the DHCP server role installed
