Flawed Cisco update threatens to stop APs from getting further patches
Cisco admins are scrambling to patch a critical flash memory overflow vulnerability in over 200 Cisco Systems IOS XE-based models of wireless access points (APs), caused by a recent flawed software update. If the issue is not corrected quickly, the AP’s memory will become so flooded that new software updates will be blocked and the AP rendered insecure, or possibly…
IPv6 may briefly have accounted for more than half of internet traffic
Has IPv6 finally reached its day of glory? It’s fair to say that IPv6 has not had the level of take-up expected when the Internet Engineering Task Force (IETF) ratified it back in 1998. Take-up has been agonizingly slow, not reaching 5 percent of traffic until 2014. However, the use of IPv6 has been slowly climbing since, and according to…

DNS Security is often inadequate, and network engineers should get more involved
Despite widespread adoption of defensive measures, most IT professionals believe their DNS infrastructure is not secure enough. Enterprise Management Associates (EMA) recently published DDI Directions 2026, a market research report that explores enterprise strategies for DNS, DHCP, and IP address management (DDI). In that report, only 28% of DDI experts said they believe that their DNS infrastructure is completely secure.…
Fixing encryption isn’t enough. Quantum developments put focus on authentication
