The document discusses securing the ICT supply chain from cyber threats. It provides examples of past cyber attacks that targeted software supply chains, such as the Xcode Ghost attack in 2015 that compromised the iOS app developer toolchain. The document also discusses the risks of hardware supply chains being compromised through tactics like planting spy chips during the manufacturing and distribution process, as was reported done by the NSA on Cisco routers and servers from Amazon and Apple. It advocates breaking the cyber kill chain and securing different components of the ICT supply chain from chips to end customers to help stop threats.
