What is 256bit encryption?
256-bit encryption is a data/file encryption technique that uses a 256-bit key to encrypt and decrypt data or files. It is one of the most secure encryption methods after 128- and 192-bit encryption, and is used in most modern encryption algorithms, protocols and technologies including AES and SSL.
What is 128bit encryption?
128-bit AES encryption refers to the process of concealing plaintext data using an AES key length of 128 bits. 128-bit AES encryption uses 10 transformation rounds to convert plaintext into ciphertext and is approved by the National Security Agency (NSA) to protect secret but not top-secret government information.
What is 64 bit encryption?
Encryption keys are measured in bits, representing how many bits of computer memory a key takes up. So a 64-bit key takes 64 bits of memory, a 128-bit key takes 128 bits, and so on. When a particular algorithm for encryption is advertised, it will typically be advertised through the length of keys it allows for.
How does AES encryption work?
The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.
What permissions do remote access users need?
Admins who deploy a Remote Access server require local administrator permissions on the server and domain user permissions. In addition, the administrator requires permissions for the GPOs that are used for DirectAccess deployment.
What is DirectAccess Remote Client Management?
The DirectAccess Remote Client Management deployment scenario uses DirectAccess to maintain clients over the Internet. This section explains the scenario, including its phases, roles, features, and links to additional resources.
What is DirectAccess configuration?
DirectAccess provides a configuration that supports remote management of DirectAccess clients. You can use a deployment wizard option that limits the creation of policies to only those needed for remote management of client computers.
What is DirectAccess client?
DirectAccess client computers are connected to the intranet whenever they are connected to the Internet, regardless of whether the user has signed in to the computer. They can be managed as intranet resources and kept current with Group Policy changes, operating system updates, antimalware updates, and other organizational changes.
How many domain controllers are required for remote access?
At least one domain controller. The Remote Access servers and DirectAccess clients must be domain members.
What happens if the network location server is not located on the Remote Access server?
If the network location server is not located on the Remote Access server, a separate server to run it is required.
Where to place remote access server?
Network and server topology: With DirectAccess, you can place your Remote Access server at the edge of your intranet or behind a network address translation (NAT) device or a firewall.
Remote file access
Basically FTP (File Transport Protocol) is used to transfer files between devices.
Telnet
Remote users can still “remote in” to computers using the Telnet command. While this is fast and efficient it is not secure. It has largely been replaced by more secure transfer methods.

In-band management requires that the program be installed on each device being configured. The device (s) being configured must be powered on limiting some of your options.
How does RDP work?
Remote Desktop and Remote Assistance use the same protocol and allow for Screen share and File share. Both program’s settings are accessed by opening Control Panel, clicking System, and then Advanced system settings . In the System Properties below, observe the Remote Assistance checkbox which enables Remote Assistance connections to the computer. The Advanced Button enables the user to Allow this computer to be controlled remotely. The maximum time a request remains open can be set as well as the operating systems that can use the service. When enabled, the user can send requests for assistance to trusted parties and allow them to troubleshoot any problems while they watch. See these options in the screenshots below:

However, this program enables authenticated users to completely control the computer, locking the local PC during the process. This is most effective when users are allowed to work remotely by connecting to their desktop from another location.
What is remote access technology?
A common remote access technology in use today is the IPsec VPN. A piece of software called a VPN client is installed on the end user’s computer and is configured with details about the target network, such as the gateway IP address and a pre-shared security key. Each time the user wants to connect to the corporate network, they start the VPN client, which creates a secure connection to the corporate firewall.
Does IT need to touch each machine?
The IT department does not need to touch each machine that needs remote access. Network administrators can set up granular security policies for specific resources on the corporate network, even down to a single web-based application. Software clients are available for mobile devices such as iPhones and iPads.

Being able to connect securely to your corporate network from a remote location using a Virtual Private Network (VPN) is important, and it may be required by your job if you are a telecommuter. There are some remote access technologies that are widely used, but some new methods have recently emerged that have the ability to change how we work.
Is DirectAccess going to be widespread?
DirectAccess is not going to gain widespread adoption until the OS licensing requirements are revised and the networking is reworked to be more straightforward. While IPv6 is the future of networking, we currently live and work in an IPv4 world, especially on the LAN (as of May 2014, IPv4 still carried more than 96% of Internet traffic worldwide, according to Google ). Setting up a new remote access technology should not require one or more potentially expensive projects before it can be deployed.
What is remote access monitoring?
Remote Access monitoring reports remote user activity and status for DirectAccess and VPN connections. It tracks the number and duration of client connections (among other statistics), and monitors the operations status of the server. An easy-to-use monitoring console provides a view of your entire Remote Access infrastructure. Monitoring views are available for single server, cluster, and multisite configurations.
What is direct access connection?
For DirectAccess, a connection is uniquely identified by the IP address of the remote client. For example, if a machine tunnel is open for a client computer, and a user is connected from that computer, these would be using the same connection. In a situation where the user disconnects and connects again while the machine tunnel is still active, it is a single connection.
What is monitoring in a network?
Monitoring shows actively connected users at a given point in time.
