The following table provides the history of updates to this version of this guide: Table 1 Change history for this guide Date Description 27 January, 2020 Beginning with the Symantec Endpoint Encryption 11.3.0 MP1 release, updated this guide to remove references for Windows 7 support. Using this guide This guide is for anyone who uses the Symantec Endpoint Encryption for BitLocker software to protect their data. The guide provides information on configuring a PIN or password for authentication. It covers the following two deployment scenarios of Symantec Endpoint Encryption for BitLocker: ■ Systems that are encrypted after Symantec Endpoint Encryption for BitLocker is installed. See “About Symantec Endpoint Encryption for BitLocker” on page 6. ■ Systems that are pre-encrypted with Microsoft BitLocker, after which Symantec Endpoint Encryption for BitLocker is installed. See “About decryption on a pre-encrypted BitLocker system” on page 10. Getting Started 6 About Symantec Endpoint Encryption for BitLocker About Symantec Endpoint Encryption for BitLocker BitLocker is the Microsoft native encryption solution to encrypt a client computer. Symantec Endpoint Encryption for BitLocker enables your administrator to manage the volumes that are encrypted with Microsoft BitLocker. Symantec Endpoint Encryption for BitLocker also allows you to regain access to encrypted volumes using Help Desk Recovery. With Symantec Endpoint Encryption for BitLocker: ■ You can encrypt or decrypt the boot volume as well as the data volumes on your client computers. ■ Your computer reports status information to the Symantec Endpoint Encryption Management Server. ■ Your computer generates a BitLocker Recovery Key and sends this key to the server. You can retrieve and use this key to access your data in case you forget your PIN or password and get locked out. Symantec Endpoint Encryption for BitLocker provides prompts, so that you know when to configure a PIN or a password. Your PIN or password serves as your logon credential. And only after you configure the PIN or password, encryption starts on the computer. Symantec Endpoint Encryption for BitLocker enables your administrator to manage the BitLocker client computers by: ■ Creating and deploying the BitLocker management software. ■ Providing the encryption and the authentication policy options. ■ Locking the client computer when a predefined time has passed and the client has not checked in with Symantec Endpoint Encryption Management Server through the client monitor feature. ■ Generating the reports that identify which computers are running BitLocker and the encryption status of the computer volumes. ■ Providing a help desk capability, if you should need to use your BitLocker Recovery Key to gain computer access. About authentication If your computer is not yet encrypted by BitLocker, your administrator applies a policy to your computer to begin encryption. Preceding encryption, you are required to configure authentication credentials. You use these credentials to authenticate to the BitLocker preboot authentication screen that appears once your system is encrypted. Your administrator can choose one of the following authentication methods: ■ TPM Getting Started 7 About Symantec Endpoint Encryption for BitLocker If the method is a Trusted Platform Module (TPM), a chip that is embedded in your computer helps prevent unauthorized access to your system and ensure a safe computing environment. The TPM provides the authentication, no user intervention, or credentials are not required. ■ TPM and PIN If the method is a PIN, you may be prompted to configure a PIN to begin encryption. Thereafter, you use the PIN to authenticate to the BitLocker preboot screen every time you start your computer. ■ A password If the method is to use a password when TPM is unavailable, you may be prompted to configure a password to begin encryption. Thereafter, you use the password to authenticate to the BitLocker preboot screen every time you start your computer. If your computer is already encrypted by BitLocker, you may already have a password or PIN that you use for authentication. You do not need to know which policy your administrator has applied to your computer. The prompts lead you through the process to configure credentials for whichever method has been chosen for you. See “Configuring a PIN for Symantec Endpoint Encryption for BitLocker” on page 7. See “Configuring a password for Symantec Endpoint Encryption for BitLocker” on page 8. Configuring a PIN for Symantec Endpoint Encryption for BitLocker If your administrator configured your preboot authentication method to be a PIN, you see a PIN configuration dialog box after Symantec Endpoint Encryption for BitLocker is installed and the BitLocker Recovery Key is sent to the server. The PIN length must be 6 - 20 digits. For improved protection, Symantec recommends that you configure your BitLocker PIN the first time the dialog

  • Why Can't I Wake My Jetdrive 850 up from Hibernation Mode? Why Can't I
    Why can't I wake my JetDrive 850 up from Hibernation Mode? If you encounter this problem while the JetDrive 850 is running on battery power, please note that this issue will happen with all NVMe SSDs, including Apple's native NVMe SSD. Our current assumption is that the NVMe driver of the Mac OS is causing it. Please run Terminal on your Mac and enter "sudo pmset -a hibernatemode 3" to reset the mode to its default value: 3. You can also check if the hibernatemode has been successfully altered by entering the command "pmset -g". Why can't I boot from my JetDrive SSD after system migration? If, after installation, your system won't recognize the JetDrive SSD as the default boot drive, and shows you an icon same as the one in the pic below, it could be because the MacOS has upgraded its security level for drives. This is more likely to occur in the 10.14 (Mojave) version. How to solve this: 1. If you have an enclosure for the JetDrive SSD, please place Apple's native SSD in it, and connect the enclosure to your Mac. If you don't have an enclosure, please use an external HDD or SSD with the MacOS installed. 2. Start your Mac, and press the "Option" key. 3. Click on any drive to enter MacOS. 4. Go to System Preferences. Go to "Startup Disk". 5. Select the installed JetDrive SSD as the default boot disk. How to clean install MacOS on the JerDrive 855/850 It is entirely normal to encounter problems attempting to clean install OS to your JetDrive 855/850, as the internet recovery will reinstall to your JetDrive the original operating system that came the same year with the Mac, and since the JetDrive 855/850 only works with High Sierra or later versions (10.13 or later), a clean install of an earlier MacOS is out of the question.

  • Recipe for Mobile Data Security: TPM, Bitlocker, Windows Vista and Active Directory
    Recipe for Mobile Data Security: TPM, Bitlocker, Windows Vista and Active Directory Tom Olzak October 2007 If your business is like mine, laptops regularly disappear. Until recently, centrally managed mobile storage encryption solutions for Windows environments were either too costly, required users to carry a key-resident device, or relied on keys residing on local disk. Sometimes the best solution under these circumstances was the presence of administrative controls (i.e. policies) prohibiting users from storing sensitive information on local laptop drives. With the proliferation of TPM 1.2 across most laptop platforms and the release of Microsoft Windows Vista, most roadblocks to laptop data encryption have been removed. In this paper, I explore the challenges facing security managers responsible for laptop data security, TPM technology, and how the features of a TPM can integrate with Microsoft’s Bitlocker and Active Directory technologies to provide for more secure data on the road. The Challenges Vulnerable Laptop Data When a mobile user’s laptop is stolen, a variety of data might be potentially exposed. The following is a short list of some of the most common types of sensitive information that might be found on a laptop drive: ¾ ePHI – Electronic Protected Health Information, protected under the HIPAA, is any information that can be used to uniquely identify a health care recipient. ¾ PII – Essentially, Personally Identifiable Information is any data that can be used to steal a person’s identity. Most states have passed laws requiring businesses to take steps to protect this information as well as to notify and assist victims if this information is compromised.

  • Policy on Computer Power Management
    Policy on Computer Power Management Purpose The Stephen M. Ross School of Business at the University of Michigan (“Ross”) has established computer power settings to achieve energy cost savings across the enterprise for all managed desktop and laptop computers. Power management is a feature of computers, monitors, printers and copiers that turns off the power or switches the system to a low-power state when inactive in order to save energy. Power management becomes even more important across an enterprise such as Ross due to the significant amount of energy being used the costs associated with that energy use. More Energy Less Energy Always On Sleep/Standby Desktop Laptop Faster Processor Slower Processor Older Processor Newer Processor Windows PC Apple Mac Heavy Use (Stats, Gaming) Light Use (Microsoft Office, Email) Online Offline Data gathering and research shows that, on average, Ross can save 200 kilowatt-hours (kWh) per computer per year by simply turning off computers when not in use. A typical computer and monitor use 200 kWh when active and only 2 to 3 watts in sleep mode. Using the UM electricity rate of $0.07/kWh against the1,200 computers and laptops at Ross, and considering hours of operation and typical use pattern, Ross would conservatively save $20,000 per year. Basic power management for the Ross environment also saves 1,500 trees and effectively removes 80 automobiles from the roads each year through lower CO2 emissions. Finally, basic power management prolongs battery life for laptops, reduces total building cooling requirements, reduces noise, and reduces operating costs for energy and cooling.

  • Power Consumption & Management: Windows Vista Versus Windows XP
    Power consumption & management: Windows Vista versus Windows XP Overview This white paper will show how British businesses running a fleet of Windows XP desktop PCs can reduce running costs by anything from £23 to £46 per system per year by switching to Windows Vista. It will also show the effect Vista’s improved power management can have on a business’s carbon dioxide emissions. It is important to note that the financial and carbon-dioxide savings are not due to a PC running Windows Vista consuming less power per task than a PC running Windows XP (for example, typing up a document in Microsoft Word will consume very similar amounts of power). Instead, it is based on real-world usage of computers. In particular, the habit of computer users to leave their PCs running even when not in use. This is more relevant to Windows Vista, as opposed to Windows XP, due to the addition of advanced power management to Group Policy, the improved reliability of Sleep mode, and, most importantly, Vista PCs being automatically put into Sleep mode after an hour of non-use.
