!!!What Is SSH Proxy Tunneling?
Imagine you are in a group of people sitting at a round table. Everyone speaks the same language English (open connections). Simultaneous conversations are going on across the table (__data transmissions__). Anything that is said could be overheard, listened to, repeated or stolen (__vulnerable__ data) from and by anyone present or in close proximity to the round table. Your conversation is not secure! You can decide to speak in another language hoping others do not understand(__encryption__). It is somewhat secure, but definitely not guaranteed. You go a step further and use a private telephone line (__secure tunnel__ ) and have a better secured private conversation across the table. With the telephone, even

As much as the internet has become the giant that it is, for our communications, it is also a source of great peril because of its security risks. Communication transmissions are therefore done within various secure environments. One such environment is the SSH tunnel. SSH (Secure shell) __Proxy tunneling__ is an encrypted tunnel that is created to allow data transmissions through a secure SSH protocol between devices over a network. This means that traffic which is unencrypted (English conversation) is given a safe and secure passage (telephone connection) to its …show more content…
Therefore, there are many methods of securing these data transmissions. We will look at the following SSH applications.
!!Encrypted File Transfers
The internet provides the largest medium for file transfer. Internet connections facilitate file access transfers and file management as a whole. An e-learning establishment for example may have cause to frequently transit large files between students and tutors as work, notes and lessons are distributed daily. Even though unsecured file transfer protocols may be established the SSH provides a secure tunnel through which these transmissions take place.
!!Secure Command Shell
Another important use of SSH tunneling is the transmission of administrative commands. Remote administration has become an invaluable tool to both system administrators and users. Has a system administrator who is not within your geographical location, ever taken control of your client machine and sorted something out? If so then you have experienced remote administration. In the execution of remote administration by system administrators from remote locations. system commands and programs such as shutdown, startup, updates and installations are executed through the secure encrypted tunnels provided by SSH on remote client machines and
1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between
It is easily configured. OpenVPN isn’t vendor supported that is why a third party application is required to run it on mobile devices and computers. 5. SSTP—SSTP is Secure Socket Tunneling Protocol.
1- A caller contacts a master server, and signals that they would like to establish a call with a responder. 2- The responder receives an encrypted signal, connects to the master server, and indicates that it has received the call signal. 3- If the responder chooses to answer the call, then it is relayed through the closest available relay server.
OUR COMPANY has recently expanded its infrastructure and now needs to ensure that authorized employees are able to access the intranet. We have many of our staff frequently traveling to remote locations, which means they need access to company documents stored on our intranet file server. By enabling our employees to access company information remotely, we need to ensure that this data is secure and that not just anyone is remotely accessing company resources. As such I think now would be a good time to talk about the various protocols we could use to help us achieve this. THE FIRST OF THESE PROTOCOLS IS L2TP which stands for layer two tunneling protocol.
Tunneling: It is the protocol that allows the secure movement of data from one network to another. UDP amplification DNS: DNS is attacks in which an attacker delivers traffic to the victim of their attack by reflecting it off of a third party so that the origin of the attack is concealed from the victim. It is substantially easier for an attacker to spoof their source address with UDP. Virtual machine:
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
On the left is the server, and on the right is the client. When I type a message and press enter on the server (left side), it is sent (locally) to the TCP client. Much like the HTTP client above, this utilizes the application layer of the TCP/IP
If your business is mainly served to your customers through a web interface, it is incredibly important to respond to web server outages, as every second costs the company more and more money. With a monitoring solution implemented and efficiently monitoring your web servers, and notifications properly configured, a system administrator can respond to outages in a timely manner, and save the enterprise precious capital. In the context of my lab, the pfSense gateway, the Wiki server, and Nagios all utilize web interfaces that can be monitored, and are being monitored by Nagios. Another important service to monitor in and enterprise environment is SSH (TCP port 22). In most instances, a system administrator will be accessing and configuring devices on the network via SSH, and in some cases, if SSH is not accessible the administrator can be completely locked out of a server or network device.
IP addresses allow network resources to be reached through a network interface. If one computer wants to communicate with another computer,
And everything which is not permitted by law is forbidden. "(Rand, 8) This tunnel that he keeps in secret with International 4-8818 helps roll in the spirit of inquiry for him to continue with the science experiments and writings only to be soon caught and
Tunnel rat- A specially trained Soldier who entered into man made tunnels in Vietnam to search for equipment, documents and prisoners. The American tunnel rat had to crawl or slide through long, narrow and most of the time pitch black tunnels. They faced death every time they entered a tunnel. The tunnels contained various items such as booby traps, mines, snakes and rats.

Telehealth offers real-time communication where a patient consults with a physician or where a nurse practitioner consults with a specialist through a link. In such cases, the patient can access primary care without going to the clinic. Reaching patients at home saves not only travel times and related practitioners and patients expenses but also improves patient survival as well as recovery. Effectiveness of the TELEHEALTH (ethical-legal issues) The effectiveness of telehealth technology is affected by issues of ethics, costs of infrastructure and legal issues.
Remote teams are becoming more and more common in modern enterprise, for many reasons. The main one is money, as it saves a considerable amount of money in a competitive market and difficult economic climate. However, many managers are questioning whether it is an ideal way to do business and whether remote working or the traditional office structure produces better results and profits. Much of it comes down to personal preference as to how each individual prefers to work, but taking the IT industry as an example, many have found that they are actually much more productive and turn in better quality work from home rather than the office. Here are just a few ways that IT professionals, and indeed people of any profession, have improved their
Surveillance and privacy Surveillance and privacy are two terms that don’t match so much. Nowadays our society is made up of people who are fond of showing themselves off in any occasion, in a gamut of ways, from social networks such as Facebook, Twitter, the most recent Instagram, to wearing nothing at all in order to look amazingly cool and “way-to-go people”. I’m not buttoned-down, absolutely, and I don’t want people to bundle themselves up. It’s no use.
