What is PPP protocol?
PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up). PPP is used most often for remote connections to LANs and ISPs. PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host ...
How to use PPTP?
To use PPTP, you’ll have to set up a PPP session between the server and the client, usually over the internet. Once the session is established, you’ll create a second dial-up session. This dial-up session will use PPTP to dial through the existing PPP session.
What is PPTP in a network?
PPTP is a remote access protocol, based on PPP, created by Microsoft. It’s used to establish virtual connections across the internet via PPP and TCP/IP, enabling two networks to use the internet as their WAN link while retaining the security benefits of a private network.

What is managed services provider?
As a managed services provider (MSP), you likely already work with remote access protocols on a daily basis. But learning how to best explain the various types of remote access protocols and their advantages and disadvantages to customers is critical in helping them understand your decisions—and why they should trust you and your services.
Is RDP the same as ICA?
RDP offers the same core functions as ICA, although there are some limitations. RDP provides remote access for Windows clients only, while ICA can provide access for numerous platforms. ICA also offers support for automatic client updates, publishing an app to a web browser, and more.
What is the line of defense for remote access?
So, you have a three-layer line of defense working to protect remote access to your network: anti-virus, firewall, and VPN. The network security team should monitor alerts from these defenses constantly.
What is remote access VPN?
The most basic form of VPN remote access is through a RAS. This type of VPN connection is also referred to as a Virtual Private Dial-up Network (VPDN) due to its early adoption on dial-up internet.
Why is IPSec VPN important?
IPSec VPN connections are also important for an employee who needs widespread access to the company’s network. A word of warning: If you are using IPSec VPN for remote access, but you are not deploying Internet Key Exchange (IKE, certificates) as an authentication method, the connection will be vulnerable.
Why is IPSEC used?
This allows IPSec to protect data transmission in a variety of ways. IPSec is used to connect a remote user to an entire network. This gives the user access to all IP based applications. The VPN gateway is located at the perimeter of the network, and the firewall too is setup right at the gateway.
What is client side VPN?
The client-side software is responsible for establishing a tunneling connection to the RAS and for the encryption of data. RAS VPNs are appropriate for small companies, requiring a remote access for a few employees. However, most serious businesses have moved on from this basic form of VPN connection.
What is IPSEC protocol?
IPSec: IPSec is an IP packet authentication and encryption method. It uses cryptographic keys to protect data flows between hosts and security gateways. The unique feature of IPSec is that it operates at the Network Layer of the Open Systems Interconnection (OSI) protocol model.
Should a company use IPSEC VPN?
A company should go for IPSec VPN remote access if it has a strong networking department with the ability to configure each employee’s hardware device individually (installing client software, enforcing security policies etc.).
What is RDP server?

In the zero trust security model, users only have the rights they need to perform the role they have. All user accounts and devices on the network are not trusted by default. This is very different from traditional security solutions that allow users full access to the target network.
What is SASE security?
SASE is a new security model, leveraging software-defined networking (SDN), that helps users connect securely to remote data centers. It includes technologies like cloud access security broker (CASB), secure web gateway (SWG), firewall as a service (FWaaS), and ZTNA (ZTNA, described above, can be a component within a SASE solution).
How does a VPN work?
VPNs allow employees working remotely to connect to a corporate network by routing their activity through a secure server. VPN systems encrypt data transmitted over the network, so that data is unusable to an attacker eavesdropping on the connection.
Can an attacker compromise a VPN?
When an attacker compromises a VPN (virtual private network), they can easily gain access to the rest of the network. Historically, many companies deployed VPNs primarily for technical roles, enabling them to access key IT systems. Today, all users, including non-technical roles, might access systems remotely using VPN. The problem is that many old firewall rules allow access for VPN clients to almost anything on the network.
Who needs privileged accounts?
Many organizations need to provide privileged accounts for two types of users: employees and external users, such as technicians and contractors. However, organizations using external vendors or contractors must protect themselves from potential threats from these sources.

Remote access technology made great progress. There are many new ways for users to access computing resources remotely, from a variety of endpoint devices. Here are some of the technologies enabling secure remote access at organizations today.
Types of Tunneling and Encryption
Tunneling involves using protocols to encapsulate or encrypt data packets so that will pass through the Internet in a secure fashion. Think of encapsulation and tunneling like peas in a pod. The peas are the data packets (unencrypted) and the pod encapsulates or encrypts the peas so they cannot be seen.
Remote Access
