What is required for remote access?
Remote computer access requires a reliable internet connection. You'll need to activate or install software on the device you want to access, as well as on the device — or devices — you want to use to get that access.
What is remote access policy in cyber security?
Remote access policy is a document which outlines and defines acceptable methods of remotely connecting to the internal network. It is essential in large organization where networks are geographically dispersed and extend into insecure network locations such as public networks or unmanaged home networks.
Why must you create a remote access policy for VPN?
Remote access VPN can be an attractive ground for hackers and malicious attackers, so an organization's server must be protected by a security or network administrator. By having an effective VPN remote access policy, you can reduce the risk of your organization's network assets and support calls from end users.

Accessing, writing to and reading from, files that are not local to a computer can be considered remote access. For example, storing and access files in the cloud grants remote access to a network that stores those files. Examples of include services such as Dropbox, Microsoft One Drive, and Google Drive.
What is remote access solutions?
The most common remote access solutions are software programs with built-in access and communication capabilities for tech admins and remote users. These tools allow admins to access employee workstations remotely and allow users to reach in-office resources from remote devices.
What is remote access tools?
Remote access programs and tools (sometimes referred to as RATs) allow access and manipulation of systems remotely from another location. Many remote access programs are legitimate tools used by all types of users to access files and data on remote computers.
How does remote connection work?
Remote access simply works by linking the remote user to the host computer over the internet. It does not require any additional hardware to do so. Instead, it requires remote access software to be downloaded and installed on both the local and remote computers.
What are the three abstractions of access control?
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 access control?
Access control is concerned with determining the allowed activities of legitimate users, mediating every attempt by a user to access a resource in the system. In some systems, complete access is granted after s successful authentication of the user, but most systems require more sophisticated and complex control.

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.
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 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 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.
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 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.
