4.2 Big Data Systems Infrastructure
Smart Cities Risks
Larger attack surface
Insecure Hardware
Bandwidth consumption
Application Risk
Amplified impact
Need for business continuity
Cyber Resilience
Recover quickly to minimise impact
Critical infrastructure important due to impact and interdependencies
Attacks on de-anonymisation
Unsorted matching risk (use randomisation)
Join using complementary data (quasi-identifiers)
Temporal attack (removing data to limit diversity or adding background data)
Infrastructure Security
Infrastructure
