Regardless of whether you are opting for a Windows of Linux dedicated server hosting, one of the apps that will be included in the control management is the firewall protection.
The role of firewalls in dedicated severs is to allow you absolute control over the data transfer configuration. To put it simply, the user can accept or deny any form of transfer.
A further functionality of the firewall is to permit encryption for all data transferred from one machine to another. Overall, the firewall comprises of a certain set of criteria and obliges the transferable data to adhere to it.
Considering that the firewalls are customizable, the user has the possibility to set different levels of trust. In general, the internet as a whole is a zone with extremely low levels of trust mainly because worms and viruses can be downloaded undetectably along with data via email or by visiting certain websites.
At the opposite end, an internal network is considered to provide the highest level of trust, as the transferred data comes from an internal source, which makes it very improbable to contain harmful elements that can render software and documents useless. Because it uses both the internet and the internal network, a dedicated server hosting is situated somewhere in the middle.
Does the intermediate level proprietary to a dedicated server entail that you are not getting the right protection when transferring data?
The short answer is no: the service providers include various security protection options, including the firewall and regular monitoring. The standard security level of a firewall will only permit connections and traffic that you have explicitly allowed.
In the eventuality that you do not possess an extensive knowledge of the required network applications and processes, then it is advisable to choose a fully managed dedicated server. An alternative would be unmark the default ‘allow’ option and simply grant firewall access solely to the apps you know.
