Digital Forensics Specialist

Job Introduction

The BBC is often required to identify, collect and analyse data in a forensic manner in order to support a number of its functions.

Whether to support responses to cyber-security incidents, internal disciplinary investigations, or external legal proceedings in which the BBC is involved, the Digital Forensics function within BBC Information Security exists to ensure that data held on BBC information systems is preserved and acquired in an evidential (and where necessary, legally-admissible) manner.

The Digital Forensics function also provides an investigatory service supporting teams such as the BBC Investigation Service, BBC Internal Audit and BBC HR investigating the use of BBC information systems where there is a suspicion that they have been used in a way that breaches BBC policy and/or to commit criminal acts.

Given the BBC-wide scope of the team's remit, occasional travel both within the UK or to the BBC's international offices may be required.
