Cyber attackers are very skilled at infiltration. They'd find ways into a house through cracks and holes that the homeowner doesn't know about. Analogically speaking, that's what the new cyber attack group dubbed "Hafnium" did when they identified several zero-day Microsoft Exchange vulnerabilities to get into target networks. With thousands of users for every Microsoft Exchange server, the attack has far-reaching implications. First, it establishes the presence of a new threat actor group in town. What else could they be up to? more

As the pandemic continues, the network operator community continues to meet online. NANOG held its 81st meeting on February 8 and 9, and these are my notes from some of the presentations at that meeting...

The common bus architecture imposed several constraints on the network that have echoed through the ensuing four decades in all kinds of ways. more
Cybercriminals are increasingly targeting Personally Identifiable Information (PII). The reason being "data is the new gold" in this digital world, and the more sensitive some data is, the more value it has.

The Domain Name System (DNS) has become the fundamental building block for navigating from names to resources on the internet. DNS has been employed continuously ever since its introduction in 1983, by essentially every internet-connected application and device that wants to interact online. Emerging from an era where interconnection rather than information security was the primary motivation, DNS has gradually improved its security features. more
