Packet based networks require a different approach to Lawful Intercept (LI) than that used in circuit switched networks. This course focuses on what Lawful Interception and Data Retention (DR) means to communications service providers in the IP and NGN areas. The course assumes a basic knowledge of IP networking (i.e. DNS, TCP/UDP, IP, RTP) and the building of services on an IP platform (e.g. SIP, SDP, FTP, HTTP). The course first looks at the regulatory context for LI and DR and how this is translated to a practical architecture.
Review of regulation: Data protection Directive; Data Retention Directive; RIPA.
Handover and Interception: ETSI standards ES 201 671 and TS 102 232.
IRI and CC handover; correlation; manual interfaces.
Handover of query results; points of retention.
Retrieval of retained records.
Operation privacy; target privacy; storage and transmission integrity.
Identifying PoI and PoR for provided services.
Interaction with other services, storage obligations (volume, time, availability).
"Good level of practical."
"Excellent presentation - very good course structure."
This structured training course seeks to build upon workbook learning through the use of group exercises, dynamic discussion and individual tasks in order to deliver an engaging and interactive module that will ensure all candidates are able to transfer their new skills into the workplace.
