Security-functionality tradeoffs in IP transition phase

Security-functionality tradeoffs are well-known fact. In general boosting IT system functionality may lead to depleting security (confidentiality and integrity) and vice-versa. Furthermore there is a tradeoff between different basic security aspects: confidentiality and availability. Increasing confidentiality level may cause decrease in availability level. The problems should be carefully analyzed, especially in the risky phase of immature, dual-stack architecture characteristic for IPv4/IPv6 transition period. The paper presents a survey of tradeoffs related to this critical, transition period¹.
