We are the Computer Security and Incident Response Team (CSIRT) for the Janet network. Part of Jisc's Security Operations Centre, our mission is to safeguard the current and future network security of Janet (steering the security policies for all Janet connections) and of our customers, creating a secure environment to conduct your online activities. Our primary function is monitor and resolve any security incidents that occur on the Janet network, with specialists tracking a range of platforms, including Unix, Linux and Windows.

These statistics only relate to information collated by Janet CSIRT and do not provide an accurate sample of security activity across the research and education sectors. The figures are frequently more closely correlated to the activity of CSIRT and our detection of events rather than their actual rates of incidence.

For example: a successful investigation by researchers into a botnet will cause that month's malware figures to rise even though the malware may have been active in previous months.

We continue to monitor the effect of the filtering of large ntp packets (> 128 bytes) at the Janet borders. Where people have had concerns we've been working with them to make sure that their work is impacted as little as possible by this measure.

The filtering has had a large reduction on the impact to Janet infrastructure but the current filtering limits still allow enough traffic through the Janet border to cause disruption for customers with 100Mb/s, or busy 1Gb/s, connections.

We've disabled our monitoring of netflow feeds for W32/Conficker/Downadup infections. Given the decreasing number of vulnerable systems, the wide awareness of this issue and the low threat posed by the malware we've decided it was no longer worth the effort and resources to maintain a system that was generating a handful of alerts each day.

Our reports of infections will continue, but they'll only be sourced from data sent to us by third parties such as Shadowserver.

If you suspect that your institution is suffering from a DDoS attack you can call on Janet CSIRT for assistance. We can help you understand and analyse the traffic, and in most cases can work with our network operations centre and transit partners to filter traffic. Where possible we work with other network providers to eliminate the sources of the attack.
