The basis of this qualitative case study was to determine how security frameworks designed utilizing the public-private partnership model aid in the identification of suggested security best practices for a telecommunications provider's critical infrastructure within the United States. The themes generated during the completion of this study-enforced ways that critical infrastructure partner organizations could identify suggested security best practices. These themes also opened up additional avenues for future research surrounding additional methods for identifying suggested security best practices such as security awareness and education. This research also established that opportunities exist for the development of additional suggested security best practices by expanding the population to include additional critical infrastructure partners and larger sectors.
