What type of authentication does a VPN use?
Most VPN solutions support different types of authentication mechanisms, depending on the type of VPN (site-to-site, remote user). One type that supports MFA is the use of RADIUS, in which the VPN server becomes a RADIUS client to a RADIUS server, which in turn is able to perform a Multi-factor Authentication. For example, CyberArk Idaptive connector software can serve as a RADIUS server as well as an AD proxy to perform the AD authentication as well as present a second factor in the form of a mobile authenticator, OATH OTP, email, for the second factor.
Is it important to grant access to devices with verified by MFA?
With users being remote, and possibly also using their own devices (BYOD), it is important to only grant access to those devices with users who were verified by MFA as part of logging into the device itself.
Is VPN safe for remote access?
The VPN is one of the most time-tested, albeit a bit risky, solution out there for secure remote access. I call it risky because, if not properly implemented and maintained, attackers might be able to exploit weaknesses to gain privileged access to sensitive systems and data. In fact, some organizations are opting for new ways to connect their remote workforces that eliminate the need for VPNs or agents and help streamline operations and user workflows.
Does anyconnect support SAML?
Does the solution support a client-less VPN authentication mechanism such as SAML? This is especially convenient since then the IT administrator does not have to ensure that each client is installed with the right version of the client and thus is able to embrace a wider range of endpoints in a secure fashion. Some clients (Cisco’s Anyconnect is an example) do have support for embedded browsers, which can then support SAML.
What is a VPN site to site?
Site-to-Site VPNs, sometimes called LAN-to-LAN or L2L VPNs connect two locations or sites together , extending a classical WAN design. Two intermediate devices, commonly called VPN gateways, protect the traffic between the two LANs. This type of VPN tunnels packets between the locations: the original IP packet from one LAN is encrypted by one gateway, forwarded to the destination gateway, and then decrypted and forwarded to the local LAN at its end to the destination. From the real source and destination’s perspective, the VPN is virtual—they do not even know their traffic is being protected between the two VPN gateways. The most common
What is VPN in business?
Virtual Private Network (VPN) is the technology that can use to access the office or home network remotely and securely over the Internet, so that the communication data is protected from hijacking by hackers. When the VPN connection is established between 2 parties (between a VPN client and vpn gateway or between 2 VPN gateways), ...
How does IPSec work?
To facilitate VPN connections, one of the VPN gateways issues a request to the other to establish an IPSec connection. The two VPN gateways exchange information with each other and create an IPSec connection. Routing on each network is configured so that as hosts on one network need to communicate with hosts on the other network, their network traffic is automatically routed through the IPSec connection, protecting it appropriately. A single IPSec connection establishing a tunnel between the gateways can support all communications between the two networks, or multiple IPSec connections can each protect different types or classes of traffic. [2]
What is the most common site to site protocol used to protect traffic?
The most common. Site-to-site protocol used to protect traffic is IPSec Routers are commonly used as the VPN gateway product, though other products can be used, such as firewalls. Cisco products that support IPSec L2L VPNs include routers, ASA and PIX security appliances, and the VPN 3000 concentrators.
What is IPSEC protocol?
IPSec is an Internet Engineering Task Force (IETF) standard suite of protocols that provides data authentication, integrity, and confidentiality as data is transferred between communication points across IP networks. IPSec provides data security at the IP packet level. A packet is a data bundle that is organized for transmission across a network, and it includes a header and payload (the data in the packet). IPSec emerged as a viable network security standard because enterprises wanted to ensure that data could be securely transmitted over the Internet. IPSec protects against possible security exposures by protecting data while in transit. [1]
What is the least commonly used VPN architecture?
The least commonly used VPN architecture is the host-to-host model, which is typically used for special purpose needs, such as system administrators performing remote management of a single server. In this case, the organization configures the server to provide VPN services and the system administrators.
Why is VPN gateway called VPN gateway?
The VPN gateway is aptly named because it functions as a “gatekeeper” for each of the computers connected on the Local Area Network behind it. In most cases, each gateway will have a “public” facing address (WAN side) and a “private” facing address (LAN side).
What is clientless VPN?
With clientless SSL VPNs, a user uses a web browser as the client software. And because most users have a web browser already installed on their PCs and are very comfortable with web browser applications, there is basically no special client software nor any learning curve involved to use the SSL VPN. SSL VPNs, however, have one limitation: because they are implemented at the application layer, only web-based applications (those via a web browser) can be protected. Other applications, by default, are not protected. In some instances, an SSL VPN vendor can write special code on the SSL VPN gateway device to handle additional applications. But as to what applications are actually supported, this will vary from vendor to vendor. In this instance, a Layer-3 VPN solution, such as IPsec or L2TP/IPsec, would be better because they can protect all traffic from the network layer and above; in other words, these VPNs are not application-specific. SSL VPNs are discussed in more depth in Chapter 5, "SSL VPNs."
What is PPP protocol?

Does GRE work on Cisco routers?
From a Cisco-product perspective, GRE works only on Cisco IOS-based routers.
Is PPTP open standard?
One problem with using PPTP is that even though the process was defined later in an IETF RFC, PPTP was a semi-open standard. In other words, if you worked in a Microsoft environment, or with vendors that worked closely with Microsoft, deploying PPTP worked well. However, PPTP typically would not work in a mixed-vendor networking environment.
Can GRE be used as a VPN?
Because of these two limitations, GRE is typically not used as a complete VPN solution; however, it can be combined with other solutions, such as IPsec, to create a more robust and scalable VPN deployment.
Is GRE a good VPN?
Given its flexibility of encapsulating many protocols, you would think that GRE would be a great VPN solution, at least compared to other VPN solutions with limited protocol support. However, GRE has two main disadvantages:
