Firewall Resource. A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined rules. The available firewall resource is built upon Ubuntu UFW (Uncomplicated FireWall), to which a control system, based on a ReST interface, has been added. The firewall agent is available for Ubuntu OS only. The rules that can be defined on this type of firewall are stateless (they do not maintain information about the context). It works as a packet filter, which looks at network addresses, ports and protocols. Services specifically available for the firewall Resource are:
1. The Experimenter can statically define a list of allowed IP addresses (or CIDR masks)
2. The Experimenter can statically define a list of denied IP addresses (or CIDR masks)
3. The Experimenter can statically define the default behaviour of the firewall
4. The Experimenter can get the status of the firewall 5. The Experimenter can get the rules installed on the firewall 6. The Experimenter can dynamically add a rule to the firewall 7. The Experimenter can dynamically update a rule on the firewall 8. The Experimenter can dynamically remove a rule from the firewall Further information and the UFW documentation can be found at xxxxx://xxxx.xxxxxx.xxx/community/UFW.
