In most edge networks, especially those with global presence, observability of traffic flow is critical to successful operations. In addition to providing operational metrics to ensure nominal functionality, the ability to divine key information from the flow of traffic - from transport to application layer - can often prove the difference between quickly detecting and mitigating a DDoS...
Deep learning brings a lot of new possibilities in the detection of previously unknown attacks. However, it could be tricky because of false positives.
We introduce how to get the benefit for your network from the research we performed with the Czech Technical University in Prague [Catania C., García S., Torres P. (2019)] to develop a new approach to identify devices infected by DGA...
DNSSEC focuses on authenticating traffic between the resolver and
the nameserver but doesn't address the security of traffic between
the stub and the resolver. It is generally impractical for a stub
to set the DO bit and re-validate DNSSEC signatures because of the
lack of a chain of trust. Determining and validating the chain of
trust from a stub would invalidate the need for a...
The ICANN managed root server system (IMRS) receives around 15 billion queries per day and a new system for traffic capture and visualisation has recently been developed. The traffic capture utilises the C-DNS (Compacted-DNS) format standardised in RFC8618 and uploads this data to a ClickHouse based data storage system. This system is capable of holding both raw C-DNS data and aggregated data...
