The Personal Security Service (PSA) use case targets SONATA’s potential to offer on-demand network security services to enable secure access and online presence.
Service Providers and Network Operators are providing device and pervasive access protection from Internet threats by offloading common security applications away from user devices by using NFV technology and creating Virtual Network Security functions (vNSF), like VPNs, firewalls, or parental controls services. The next steps in this evolution consist in personalizing these vNSFs per customer, allowing them to define their own rules and policies in security, triggered by different preferences.
The ISP creates and offers a security service catalog, where customers, aware of security risks, can search and subscribe to a security service. The customer selects the preferred offering: a subscription based on, for example, time of use, volume of data, a flat rate, etc. The orchestration, deployment and monitoring process of a set of virtual Network Security Functions (vNSFs) is triggered, combining those services required by the user. The customer may decide to change their service's configuration (e.g. by applying some additional incoming filters) and SONATA reconfigures the service accordingly. For example, this could result in adding and deploying a new vNSF with Parental control and the list of blocked webpages as part of the configuration.
