When it comes to securing a supply chain, there are several key strategies that businesses should consider. Firstly, organizations should ensure that all software used in the supply chain is kept up-to-date with regular patching. This is important as any vulnerabilities in the software can be exploited by attackers. Secondly, companies should also ensure that access control measures are implemented throughout the entire system. This includes limiting user privileges and setting up two-factor authentication processes wherever possible. Thirdly, business networks should also be segmented so that if an attacker does gain access to one part of the system, they cannot spread across into other areas of the network.
