How socially aware are social media privacy controls?

Social media sites are key mediators of online communication. Yet the privacy controls for these sites are not fully socially aware, even when privacy management is known to be fundamental to successful social relationships

Assurance Techniques for Industrial Control Systems (ICS)

Assurance techniques generate evidence that allow us to make claims of assurance about security. For the purpose of certification to an assurance scheme, this evidence enables us to answer the question: are the implemented security controls consistent with organisational risk posture? This paper uses interviews with security practitioners to assess how ICS security assessments are conducted in practice, before introducing the five "PASIV" principles to ensure the safe use of assurance techniques. PASIV is then applied to three phases of the system development life cycle (development; procurement; operational), to determine when and when not, these assurance techniques can be used to generate evidence. Focusing then on the operational phase, this study assesses how assurances techniques generate evidence for the 35 security control families of ISO/IEC 27001:2013
