What Is SSTP?

How Secure Is the SSTP Protocol?


As we saw in Part 1, we want our SSTP-protected network to be as secure as possible. Let's start off by thinking about why it would be important to have as secure a VPN tunnel as possible. From the security standpoint, it is important because: The VPN server is the only point of contact between your SSTP-protected network and the Internet. All other hosts that connect to your network are behind a gateway and have no idea what the traffic looks like inside the VPN server or what protocols it is talking. If someone gets into your network, they could access anything else on the network with ease.

If we make changes to the rules that we apply at the firewall, then the whole network needs to be updated. It would be a real headache for IT support if there is a network change and you have to have all the users who need to change their rules manually change their rules. If, for example, you create an IPsec rule for incoming connections from a source port range, you don't want to accidentally include all incoming connections. Even if you create a new IPsec rule, if you have to make changes to clients on the VPN server, or vice versa, the whole process starts over again and can cause you major headaches. It's too easy for a simple typo to cause havoc. A better solution would be to have your rules centralized and to have the SSTP client do the work of applying rules to the firewall, but we'll talk more about this another time.

As mentioned, there are various ways to break the communication between a client and its gateway. So, to prevent this, we want to limit the attacks and minimize the chance that these attacks will happen. Therefore, we need to take steps to secure the traffic between the client and the gateway. This includes encrypting the traffic and using SSTP to help make sure the traffic looks right to the gateway.

How does SSTP help with firewall rules? As we discussed in Part 1, SSTP is used by the gateway to verify the traffic and decide if it should go through the firewall or not. SSTP will decide if the traffic looks okay or if there is a problem with the rules that the firewall is applying.

What Is SSTP?

The SSTP (Self-Sufficient Tree Production) method is a very simple approach to forestry that has been practiced for thousands of years. It was developed by the late Dave Jacke in North America and later modified by Professor Richard Youngs in the United Kingdom. SSTP is a hands-off forestry method that uses no machines or chemicals and employs only manual labor to create a natural environment where the trees grow and thrive. Today, SSTP is now used by over 5 million people worldwide in a wide variety of environments and for many applications.

Benefits of SSTP. The benefits of SSTP include: A reduction in harmful chemicals;. Removal of invasive species;. The formation of a diverse, healthy and rich forest with low maintenance;. A reduction in erosion and runoff;. The restoration of wildlife habitat;. Fewer pests;. Lifetime savings for homeowners; and. Fewer tree casualties. SSTP Benefits. There are several types of SSTP systems including: SSTP as a single tree system;. SSTP as a tree row system;. SSTP integrated into other systems; and. SSTP at a national level. For each system there are significant benefits that the individual homeowner can expect. The main advantage is that you can be one of the 5 million people worldwide who are using the system today.

SSTP - The Single Tree System. SSTP as a single tree system is a very simple approach to forestry that was developed in the 1930's by Dave Jacke in North America. The term self-sufficient refers to the fact that this is a completely manual system without any technology. SSTP is based on what is known as the green concept in forestry. This is a philosophy that emphasizes the importance of soil, water and air quality and that there should be as little man-made intervention as possible in the system.

A good example of this is the SSTP system. With SSTP, you will not need to buy any equipment to get a functioning system that can keep trees healthy and productive. You may be able to purchase the soil preparation tool and tree spacers, but these are optional items.

What is Secure Socket Tunneling Protocol used for?

The Secure Socket Tunneling Protocol (SSTP) is a transport layer protocol developed by Microsoft. It is designed to replace the IP over Ethernet (IPoE) protocols for use with wireless networks. SSTP can work with 802.11n/g/i to carry IP packets over wired or wireless networks without the need for an IP header. If there is no IP packet to be transported on the local port, SSTP automatically falls back to IPoE for communication using Layer 2 encapsulation. SSTP can also provide Layer 2 services to allow a single IP packet to reach more than one destination and support dynamic Layer 2 routing over a single physical medium to provide Layer 2 multicast routing capability over IP networks.

Why should we use SSTP

Some of the good reasons to use Secure Socket Tunneling Protocol are as follows: The SSTP enables the network devices, such as network switches and access points, to process the Layer 3 and the upper layer packets. This means they can perform routing, security and firewalling decisions using only Layer 3 information.

By tunneling the upper layer packet over Layer 2, IPoE provides the network devices the ability to perform security and firewalling decisions without requiring any knowledge of the IP packets. It is based on the principle of sending only the required information to ensure efficiency.

A tunnel is a communication session established through a device which relays the entire message. Layer 2 tunneling uses the layer 2 mediums to enable the device to relay the entire message when used between two separate layer 3 hosts. The Layer 2 tunneling is accomplished through the use of logical interfaces and/or interface address pairs.

Using the SSTP as a part of our application in our design is more secure than using the IPoE. In IPoE, the data is carried over a dedicated link called the ethertype field. In SSTP, the data is carried over non-identical links which are referred to as ethertype fields. Hence, the information that must be passed through the network is limited to only Layer 3 information in SSTP. All Layer 2 information has been stripped from the information that must be transmitted through the network.

What is the difference between SSL VPN and SSTP?

It seems like every cloud provider has an SSTP (secure shell tunneling protocol) or SSL VPN. Is one better than the other? SSL VPN is a generic name for a VPN-like technology. Some products use SSL, some use OpenVPN.

SSTP is a protocol that can be used in many different VPN solutions. The main difference is that SSTP isn't encrypted, so it can't be used to provide confidentiality between two endpoints, and it doesn't have the option to create new SSL VPN tunnels. It can be used with a SSL connection to provide encryption between endpoints.

Can I disable Secure Socket Tunneling Protocol service?

I am trying to disable Secure Socket Tunneling Protocol (SSTP) on Windows XP. It says it is running but how can I stop it from running? The only way I found to stop it is to open cmd.exe and enter the following: stop sstp. How do I do that from a batch file? You can run the sc config command to delete an service: sc delete sstp. Or you can stop/remove the service entirely: net stop sstp. And since you're likely using Vista or later, you can just open the Services Control Panel and find the service in question.
