The use of large-scale IP address sharing technologies (commonly known ::: as "Carrier-Grade NAT" and "A+P") presents a challenge for law ::: enforcement agencies due to the fact that incoming source port ::: information is not routinely logged by Internet-facing servers. The ::: absence of this information means that it is becoming increasingly ::: difficult for law enforcement agencies to identify suspects in ::: criminal activity online. This document considers the reasons why ::: source port information is not routinely logged by Internet-facing ::: servers and makes recommendations to help improve the situation. A ::: deployment maturity model has been developed and a study of the ::: support for logging incoming source port information in common server ::: software is also presented.
This document defines common requirements for Carrier-Grade NATs ::: (CGNs). It updates RFC 4787.
ABSTRACTWe investigated collection development within the system of information support of research in Russia at the state-funded level. The analysis has been performed from the point of view of the structure and research output of Russian science. We employed the method of bibliometric analysis using InCites by Clarivate Analytics. Our results demonstrate that the state-funded set of subscriptions provides more than 55% of total world output and meets about 70% of the communication needs of Russian researchers in all Essential Science Indicators research areas. A strong correlation of informational support and research output is demonstrated.
