Any organization with an online presence wants to ensure that this presence is seamless, and that users and customers can constantly access their website for information, or to purchase goods and services. A network administrator ensures that this technical support is solid, and works to quickly resolve any potential issues within the network, to make sure that all systems are a go when it comes to the organization.


This often includes testing the network for weaknesses, which could lead to resolving more deep-seeded technical issues that could have been lethal to the company’s growth. It also includes utilizing specific e-mail and internet filters to protect the organization from outside threats of all kinds, and ensuring that the company’s network is updated in every sense possible.

 

A network administrator’s role can be very different, depending on the organization, but almost always requires a diligent eye and a pro-active attitude when it comes to protecting the security and productivity of a company or organization. The position requires a tremendous amount of technical knowledge, and without network administrators, organizations would be susceptible to more attacks, and have much less network resilience, which is essential in terms of overall productivity.

    The goal of the project is to create VPN servers that are behind a router that blocks incoming connections. Just like in a normal VPN application, when you connect to the VPN server you can send and receive network packets using the IP address of the VPN server (and perhaps also access shared network drives), but the biggest difference here is that you cannot just connect to an open/filtered port...
