What is remote access VPN?
A remote access virtual private network (VPN) enables users who are working remotely to securely access and use applications and data that reside in the corporate data center and headquarters, encrypting all traffic the users send and receive.
Why is remote access important?
The security of remote access servers, such as VPN gateways and portal servers, is particularly important because they provide a way for external hosts to gain access to internal resources, as well as a secured, isolated telework environment for organization-issued, third-party-controlled, and BYOD client devices. In addition to permitting unauthorized access to enterprise resources and telework client devices, a compromised server could be used to eavesdrop on communications and manipulate them, as well as a “jumping off” point for attacking other hosts within the organization. Recommendations for general server security are available from NIST SP 800-123, Guide to General Server Security. Remote access servers should be kept fully patched, operated using an organization-defined security configuration baseline, and managed only from trusted hosts by authorized administrators.
What is a portal in remote access?
A portal is a server that offers access to one or more applications through a single centralized interface. A teleworker uses a portal client on a telework client device to access the portal. Most portals are web-based—for them, the portal client is a regular web browser. Figure 2-2 shows the basic portal solution architecture. The application client software is installed on the portal server, and it communicates with application server software on servers within the organization. The portal server communicates securely with the portal client as needed; the exact nature of this depends on the type of portal solution in use, as discussed below.
What is remote desktop access?
remote desktop access solution gives a teleworker the ability to remotely control a particular PC at the organization, most often the user’s own computer at the organization’s office, from a telework client device. The teleworker has keyboard and mouse control over the remote computer and sees that computer’s screen on the local telework client device’s screen. Remote desktop access allows the user to access all of the applications, data, and other resources that are normally available from their PC in the office. Figure 2-3 shows the basic remote desktop access architecture. A remote desktop access client program or web browser plug-in is installed on each telework client device, and it connects directly with the teleworker’s corresponding internal workstation on the organization’s internal network.
Where should a remote access server be placed?
Intermediate remote access servers connect external hosts to internal resources, so they should usually be placed at the network perimeter. The server acts as a single point of entry to the network from the perimeter and enforces the telework security policy. If remote access is needed to a particular sub-network within the organization, there are generally two options: 1) place the remote access server at the edge of the sub-network, where the sub-network joins the full network; or 2) place it at the perimeter of the full network and use additional mechanisms to restrict the teleworkers to only be able to access the specified sub-network. The value of placing the remote access server at the network perimeter versus the sub-network perimeter differs for the four types of remote access methods:

What is the key component of controlling access to network communications and protecting their content?
major component of controlling access to network communications and protecting their content is the use of cryptography. At a minimum, any sensitive information passing over the Internet, wireless networks, and other untrusted networks should have its confidentiality and integrity preserved through use of cryptography. Federal agencies are required to use cryptographic algorithms that are NIST-approved and contained in FIPS-validated modules. The FIPS 140 specification, Security Requirements for Cryptographic Modules, defines how cryptographic modules are validated.24 It is important to note that for a remote access system to be considered compliant to FIPS 140, both sides of the interaction must have passed FIPS 140 validation. Many remote access systems, such as SSL VPNs, support the use of remote access client software from other vendors, so there may be two or more distinct validation certificates for a particular remote access system.
What is remote access?
Remote access is access to organizational systems (or processes acting on behalf of users) that communicate through external networks such as the Internet. Types of remote access include dial-up, broadband, and wireless. Organizations use encrypted virtual private networks (VPNs) to enhance confidentiality and integrity for remote connections. The use of encrypted VPNs provides sufficient assurance to the organization that it can effectively treat such connections as internal networks if the cryptographic mechanisms used are implemented in accordance with applicable laws, executive orders, directives, regulations, policies, standards, and guidelines. Still, VPN connections traverse external networks, and the encrypted VPN does not enhance the availability of remote connections. VPNs with encrypted tunnels can also affect the ability to adequately monitor network communications traffic for malicious code. Remote access controls apply to systems other than public web servers or systems designed for public access. Authorization of each remote access type addresses authorization prior to allowing remote access without specifying the specific formats for such authorization. While organizations may use information exchange and system connection security agreements to manage remote access connections to other systems, such agreements are addressed as part of CA-3. Enforcing access restrictions for remote access is addressed via AC-3.

Software-based authenticators that operate within the context of an operating system MAY, where applicable, attempt to detect compromise (e.g., by malware) of the user endpoint in which they are running and SHOULD NOT complete the operation when such a compromise is detected.
What is a look up secret?
A look-up secret authenticator is a physical or electronic record that stores a set of secrets shared between the claimant and the CSP. The claimant uses the authenticator to look up the appropriate secret (s) needed to respond to a prompt from the verifier. For example, the verifier may ask a claimant to provide a specific subset of the numeric or character strings printed on a card in table format. A common application of look-up secrets is the use of "recovery keys" stored by the subscriber for use in the event another authenticator is lost or malfunctions. A look-up secret is something you have.
