Full disk encryption to prevent the loss of sensitive data McAfee Drive Encryption is full disk encryption software that helps protect data on Microsoft Windows tablets, laptops, and desktop PCs to prevent the loss of sensitive data, especially from lost or stolen equipment.
Download Solution Brief. Seamless encryption without impacting performance. Strong access control and data encryption. Certified encryption technology. First, best security practice aims to limit the number of users that can access a system to the smallest group of users. Second, assigning large numbers of users to each node might affect the overall scalability of the entire system and reduce the maximum number of nodes that DE can support.
The following penalties apply if you allow 5, users to log on at preboot on a computer: Activation takes longer because it needs to download all information about the 5, users. Synchronizing user information takes longer, increasing the workload on the ePO server. Other actions that include user information take longer to process. An example of these actions is Saving the Machine Information about a client, because it also includes user information.
Scalability of an ePO server can be affected.
Your ePO server performs more work per agent-server communication intervals ASCI to ensure that all information is up to date. Example Suppose that you have systems that each have 5, users assigned. Take the most common occurrence, a changed password. For a user, that would be captured on one system, uploaded to ePO, and then pushed down to the other 99 systems when they sync with ePO.
If you force users to change their passwords every 90 days, 5, users must update their password. The result is , updates 5, users x systems that the ePO server must process at various times as the systems synchronize with ePO. All this traffic is handled across the network. If one of your systems has a slow link, it could take a considerable amount of time to receive all changes. If the server is handling user updates for many clients, the network traffic could also be significant. In the worst case, it might not receive all updates in a sync period.
What is AOAC? They all basically refer to the same high-level functionality. It is the ability to keep a system in a low-power sleep mode, periodically wake it to retrieve data, such as emails or Facebook updates, and then have it go back to sleep again. This activity occurs without the user knowing or intervening.

Think of it being similar to the way your mobile phone works. Support is provided through Connected Standby. While it is in this standby mode, the Windows logon is used to protect the data from unauthorized access. Full disk encryption has historically been about protection of data at rest when the system is turned off.
Native encryption management for Windows and Macs
Various companies are introducing AOAC functionality and driving user expectations that their system will always contain fresh content. With the AOAC model, the system and services need to be able to access the disk. That means the encryption key for the disk always remains in memory. But systems that support AOAC are more vulnerable to cold boot style attacks because the key is always in memory. Remember that the system does not turn off; it is only in standby. When the system is sleeping, the data is never at rest with the AOAC model. The systems are not turned off; they are only in standby.

The AOAC model requires the disks to remain 'unlocked' because: Systems might wake periodically or via a push notification. Applications and Services might require access to the disk during this awake period. You can use AOAC functionality with preboot, the autoboot functionality, or both.
Features Added in 6.6.3
This functionality works regardless of your method of authentication. How does DE harden systems against cold boot attacks? A high-level overview of this new DE functionality is that on modern Windows platforms that can support the new 'Connected Standby' mode, the user can have an iPad-like experience. These systems are always in a powered-on state requiring the encryption key to be always in RAM, making them susceptible to memory scrubbing attacks that can scrub the encryption key from RAM. DE can operate behind the scenes delivering a native Windows experience to the end user.
When the device enters the 'Connected Standby' state, DEerases the encryption key from RAM and moves it to a secure area on Intel hardware hardening systems to prevent against cold boot and memory scrubbing attacks. When the device moves into an active state, the encryption key is transparently moved back to RAM after successful user authentication to Windows.
Back to Contents What is a cold boot attack? A cold boot attack is a way of extracting sensitive data from system memory when the system is turned on or in a standby state, even if the system is protected by a Windows password. The attack involves either of two actions: Hard rebooting the system and running a small program on the next boot cycle that scans system memory for sensitive information Removing the RAM from a powered-on system and translating to another system for scanning Additional Cold Boot general facts: DE hardens systems against a cold boot attack when a system enters one of the standby modes.
It is stored in a secure location that is still accessible while in Connected Standby. The system continues to function as an end user expects; but, the system is less vulnerable to a cold boot-style attack because the key is no longer in memory. DE completely removes the key from memory. This functionality hardens the system against memory-style attacks. Although every effort has been taken to ensure that the key is removed from memory, McAfee cannot guarantee that it is completely removed because of the way Windows manages memory. Further hardening work will be done on this functionality in future releases.
The only condition in which the key is put back into memory is after a user has successfully authenticated to Windows. Simply having Windows running does not put the key back into memory. When the key is not in memory, it is held in a secure storage area that is not in memory.
The key can be removed from memory when any of the following events occur: The system is turned off. The user logs off. The user locks the workstation.destcobourredan.tk

The system is waiting for a user to authenticate at the Windows logon prompt. After the system wakes up from standby or sleep. Looked at another way, if users have authenticated and they are at their desktop, the key is in memory. If users have not authenticated, or are not at their desktop, the key is not in memory.
Although only one driver is required to handle the key in memory, it does operate in one of two modes. It is a state of the encryption driver where: Encryption key is stored in RAM.
