Which VPN topology is also known as a hub-and-spoke configuration? Dominik September 6, 2020 Anonymity The so-called “hub-and-spoke configuration” is a colloquial name for a centralized VPN structure which uses a single tunnel to reroute traffic; one networking pivot to rule them all, whereby “rule” means host a...

Which VPN tunneling protocol uses IPSec with 3DES for data confidentiality? Dominik September 6, 2020 Anonymity The most widely adopted protocol that leverages Triple DES encryption to ensure data confidentiality is ESP, short for “Encapsulating/Encapsulated Security Payload.” Along with the Authentication Header (AH)...

What UDP port is used for IKE traffic from a VPN client to server? Dominik September 6, 2020 Anonymity Client-server Internet key exchange goes through user datagram protocol port 500, 4500, or both. This is a direct result of IPSec being an integral part of the IKEv2 specification. It’s also why e.g. ESP com... Read More...
Which VPN protocol leverages web-based applications? Dominik September 6, 2020 Anonymity Secure Sockets Layer (SSL) is arguably the most widely used VPN protocol that doesn’t just play nicely with web apps but is pretty much designed around the notion of having a healthy developer community. Tha... Read More...
For domain-joined computers, what is the simplest way to configure VPN connections? Dominik September 6, 2020 Anonymity If you’re already connected to a domain, then the most sensible road to graduating to an active tunneling node is paved with the shapes of good ol’ manual edits made directly to Group Policy Preferences. In ... Read More...
How does a virtual private network (VPN) provide additional security over other types of networks? Dominik September 6, 2020 Anonymity Most other types of private networks exist for the sole purpose of making computer connectivity more readily accessible. While a *virtual* private network can most certainly do that as well (that’s pretty much ... Read More...
Which VPN protocol works at Layer 3 and can encrypt the entire TCP/IP packet? Dominik September 6, 2020 Anonymity By being a component of the IPv4 enhancement, the IP security (IPSec) protocol suite operates as (not “at” - as) the so-called layer 3 of an Open Systems Interconnection (OSI) model. The said structure has s... Read More...
Which VPN protocol uses UDP port 1701 and does not provide confidentiality and authentication? Dominik February 22, 2020 Anonymity Layer Two Tunneling Protocol (L2TP), itself an augmentation of the Point-to-Point Tunneling Protocol (PPTP), is a VPN protocol that leverages User Datagram Protocol (UDP) port 1701. Unfortunately, it does n... Read More...
Which process is used to protect transmitted data in a VPN? Dominik February 22, 2020 Anonymity Symmetric key encryption and public-key encryption are the basis for any VPN, no matter how modest or convoluted, and that's the answer to your question. These are paired with at least one of the following ... Read More...
Before IPSEC can be used as a virtual private network (vpn) service, what must be created? Dominik February 22, 2020 Anonymity A secure client-server connection based on a trusted certificate is the main prerequisite for any VPN service based on the IPSec specification. The process of creating this link is so important that it has i... Read More...
When employees have multiple concurrent connections, what might be happening to the vpn system? Dominik February 22, 2020 Anonymity Such a scenario tends to go hand-in-hand with a variety of security issues due to a limit on the number of concurrent tunneling nodes any given client can handle at once. In other words, a VPN system may be dea... Read More...
What does a VPN use to ensure that any transmissions that are intercepted will be indecipherable? Dominik February 22, 2020 Anonymity Tunneling protocols allowing for two-way data traffic encryption are the basis of any and every virtual private network. Countless doctorates have already been written on the subject of cryptography, not to ... Read More...
