timefind v1.0.2.2 released

timefind v1.0.2.2 has been released (available at https://ant.isi.edu/software/timefind/).

Scientists at Los Alamos National Laboratory and at USC/ISI have developed two tools to handle indexing and selection of multiple network data types: indexer and timefind.

Most of us have processed large amounts of timestamped data. Given .pcap spanning 2010-2015, we might want to downselect on a time range, e.g., 2015-Jan-01 to 2015-Feb-01. An existing way to downselect would be to build fragile regexes and walk the directory tree for each search: inefficient and inevitably re-written.

indexer will walk through all your data and index the timestamps of the earliest and latest records.

timefind will then use the indexes and retrieve the filenames that overlap with the given time range input. To downselect 2015-Jan-01 to 2015-Feb-01 on “dns” data, use:

timefind --begin="2015-01-01" --end="2015-02-01" dns

It’s that simple and consistent.

Digit tool for T-DNS privacy updated to match current internet-draft

Digit is our DNS client side tool that can perform DNS queries via different protocols such as UDP, TCP, TLS. This tool is primarily designed to evaluate the client side latency of using DNS over TCP/TLS.

IANA has allocated port 853 to use TLS/DTLS for DNS temporarily in the most recent version of Internet draft “DNS over TLS: Initiation and Performance Considerations” (draft-ietf-dprive-dns-over-tls-01).

To track the current specification, we have updated Digit to do direct TLS on port 853 by default, with TCP. STARTTLS and other protocols as options for comparison.

These changes are available as Digit-1.4.1 at https://ant.isi.edu/software/tdns/index.html.

student recruiting for Fall 2016

ANT will be looking for one (or perhaps two) strong PhD students interested in our areas of research to start at USC in Fall 2016. If you’re interested in working with our research group, please apply to our PhD program (the deadline is December 15, 2015 and the CS department has application information).

For MS students at USC, we sometimes to directed research projects, usually as part of CSci551 or CSci651–if you’re interested, please read our webpage with specific MS-student advice.

For undergraduates interested in research, please see our webpage with specific undgraduate-student advice.
