Portfolio

I constructed a platform to allow ISPs to retrospectively investigate malicious activity directed towards their customers.

The platform consists of high-speed processing of Netflow streams from ISP infrastructure, combined with a Hadoop cluster that can provide a range of reports regarding a given customer IP address.

Cloud computing platform for network instrusion analysis

A number of command line tools for a range of customers:
- Backup maintenance scripts
- Customised version of chmod
- Tools for parsing/reformatting/analysing bulk text data

Linux tools and scripts

Design and implementation of a Linux based cluster of NVIDIA GPUs to perform bulk signing of e-mails, demanding a throughput of 10,000 e-mails per second per node.

Distributed DKIM generator with CUDA

This project was to help a network administrator identify the IP addresses and Autonomous Systems that were responsible for the traffic entering his network.

1 minute summaries of network activity were constructed from live captures and databased with MySQL. The highest hitting IP addresses were automatically queried against whois to ascertain the Autonomous System. A PHP interface then allowed the user to search the data based on IP, AS number, or date and time of activity.

Network monitoring software

This Apache module was produced to partner with a proprietary browser which rendered data from websites hosting protected content. The module was required to reformat and encrypt pages for the intended browser. The module was implemented to only protect content on the server for which a licence had been purchased.
