Rapid Development for DNS Firewalls
Recent increases in cybercrime rates mean that information security is getting more important every day. Things that were optional just a few years ago are rapidly becoming mandatory, which is why new technologies are being developed every day. Government agencies are also starting to get involved in the process. The Government Communications Headquarters of the United Kingdom, or GCHQ, is working towards the adoption of a national DNS firewall for all of Britain.
The Great British Firewall
The proposed firewall would require constructing a unified DNS system for all of Britain, which is a massive undertaking. The GCHQ intends to put the plan into action by working with Britain's major communication companies, including Virgin Media, Talk Talk, and BT. The partnership would allow the dns firewall to be implemented by the Internet providers themselves, thereby blocking dangerous sites entirely and preventing the consumer from needing to worry about that sort of information security. The firewall is expected to give users the chance to opt out of using it, for the benefit of both users who have concerns about their privacy and those who want to use an alternative security system.
The project is still in the earliest stages of development, so it will be some time before the firewall comes into use. The project's details have not been released at this point, since it remains quite likely that some of them will change before the GCHQ and its partners can complete their work on the project.
A Cloud-Based Firewall
The United Kingdom's proposed system takes place on an unprecedented scale, but it relies on technologies that are already in use. Many private individuals and businesses have come to rely on DNS firewalls to protect themselves from cybercrime. Their recent increase in popularity has encouraged private corporations to develop new security options for their clients.
One of the latest developments in the field is a cloud-based DNS firewall from eSentire. The firewall, which was announced in March at the 2016 RSA conference, relies on a connection to an open threat tracer called Cymon in order to maintain an accurate an accurate list of threats that need to be blocked. The fact that the system does not require any hardware or software installation before it can functions means that it can provide security for any device that is attached to a given network regardless of the device's operating system.
