What is access control in security?
Access control is a data security process that enables organizations to manage who is authorized to access corporate data and resources. Secure access control uses policies that verify users are who they claim to be and ensures appropriate control access levels are granted to users.

What should be included in an access control policy?
Organizations planning to implement an access control system should consider three abstractions: access control policies, models, and mechanisms. Access control policies are high-level requirements that specify how access is managed and who may access information under what circumstances.

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 a health check for telework?
After verifying the identity of a remote access user, organizations may choose to perform checks involving the telework client device to determine which internal resources the user should be permitted to access. These checks are sometimes called health, suitability, screening, or assessment checks. The most common way of implementing this is having the remote access server perform health checks on the teleworker's client device. These health checks usually require software on the user’s device that is controlled by the remote access server to verify compliance with certain requirements from the organization’s secure configuration baseline, such as the user’s antimalware software being up-to-date, the operating system being fully patched, and the user’s device being owned and controlled by the organization. Fewer health checks are generally available on mobile devices, but an important check usually provided is to determine if a mobile device has been rooted or jailbroken, which can have serious negative security implications.23
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.
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 telework in business?
Many people telework (also known as telecommuting), which is the ability for an organization’s employees, contractors, business partners, vendors, and other users to perform work from locations other than the organization’s facilities. Teleworkers use various client devices, such as desktop and laptop computers, smartphones, and tablets, to read and send email, access websites, review and edit documents, and perform many other tasks. These client devices may be controlled by the organization, by third parties (the organization’s contractors, business partners, or vendors), or by the users themselves (e.g., BYOD). Most teleworkers use remote access, which is the ability for an organization’s users to access its non-public computing resources from external locations other than the organization’s facilities.
What is a telework document?
The purpose of this document is to assist organizations in mitigating the risks associated with the enterprise technologies used for telework, such as remote access servers, telework client devices (including bring your own device [BYOD] and contractor, business partner, and vendor-controlled client devices, also known as third-party-controlled devices), and remote access communications. The document emphasizes the importance of securing sensitive information stored on telework devices and transmitted through remote access across external networks. This document provides recommendations for creating telework-related policies and for selecting, implementing, and maintaining the necessary security controls for remote access servers and clients.
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.
