4/27/10 Intrusion Detection with Mobile Sensors

posted April 14th, 2010

Our final meeting of the semester will be held April 27 at 7:00pm in CS209A. In this meeting lies the fate of SIG-SEC: we will be electing officers for next year. If you’re interested in all about SIG-SEC, either come vote on officers or run for a position. The various positions are as follows:

  • Co-Chars – Two people are elected as the SIG-SEC overlords. They keep the other officers sane and do legwork talking to potential speakers
  • Secretary – Writes down officer meeting notes and is in charge of the sign-in sheet at meetings to track attendance
  • Publicity – Advertises SIG-SEC meetings and events
  • University Relations – Makes room reservations for meetings and events
  • Special Projects – Comes up with ideas for fun stuff to do and coordinates events. Some examples include our annual wireless security audit, wireless scavenger hunt and capture the flag competitions
  • Also, Missouri S&T’s Dr. Chellappan will be giving a presentation on intrusion detection with mobile sensors.

    Abstract: In this talk, Dr. Chellappan will discuss issues in Intrusion Detection with Mobile Sensors. The talk will first present the problem in brief detail, along with the motivation and state of the art in Mobile Sensors. Then the problem of intrusion detection with mobile sensors will be formulated, followed by algorithms to optimally solve the problem. The talk will conclude with some open issues of security with mobile sensors.

    Bio: Sriram Chellappan is an Assistant Professor in the Dept. of Computer Science at Missouri University of Science and Technology since January 2008. He received his Ph.D. degree from the Dept. of Computer Science and Engineering at The Ohio-State University in December 2007.

    Sriram’s broad research interests are in Networking, Network Security and Mobile Computing. In particular, his research focuses on Security in Overlay Networks, Performance and Security in Wireless Sensor Networks and Performance Optimizations in Vehicular Networks.

    2/23/10 Secure Multiparty Computation and its Applications in Privacy-Preserving Data Analysis

    posted February 5th, 2010

    On our meeting Tuesday, February 23 at 7:00pm in CS209A, Dr. Jiang will be presenting on Secure Multiparty Communication. Dr. Wei Jiang is an Assistant Professor in the Department of Computer Science at Missouri University of Science and Technology. He received Bachelor’s degrees in both Computer Science and Mathematics from the University of Iowa, Iowa City, Iowa, in 2002. He received a Master’s degree and a Ph.D. in Computer Science from Purdue University, West Lafayette, Indiana, in 2004 and 2008 respectively. His research interests include privacy-preserving data mining, data integration, privacy issues in federated search environments, and text sanitization.

    Two millionaires, Alice and Bob, want to know who is richer, but they do not want to disclose how much money they have to each other. This can be achieved through a Trusted Third Party (TTP). Can we achieve the same objective without a TTP? Secure Multiparty Computation (SMC) techniques were specifically developed to solve this kind of problem. In this talk, we will introduce the concept of SMC and a generic solution to compute any two-party function securely. In addition, we will show how SMC concepts can be applied to protect data security and personal privacy in distributed data analysis, e.g., how police can query an FBI database for suspected criminal activities without disclosing what he or she is looking for to the FBI.

    2/10/10 Red Teaming: It’s Good to Be Bad by Will Atkins

    posted February 2nd, 2010

    The next SIG-SEC meeting will be held Wednesday February 10th, 7:00pm in CS209A. Former SIG-SEC co-chair Will Atkins will be visiting and giving a baller presentation on Red Teaming. Here are the goods regarding the talk:

    Given their roles in enabling services and functions vital to modern societies, critical information and control system infrastructures present high-value targets for the adversaries of such societies. Protecting these systems against digital attack is exceedingly difficult, as thousands of vulnerabilities in such systems are discovered every year. Red teaming, the general concept of a defensive team simulating one or more adversaries, is a useful technique for identifying which critical systems an adversary may choose to attack and how they may go about executing such attacks. This talk will address various types of red teaming, introduce a generic adversary model, overview Sandia National Laboratories’ Information Design Assurance Red Team (IDART), and reveal some of the tools and techniques used by IDART when performing red team assessments.

    For those of you that aren’t familiar with the former SIG-SEC star, William D. Atkins is a Member of Technical Staff in the Critical Infrastructure Systems Department at Sandia National Laboratories, where he conducts information assurance research and engages in red teaming exercises to secure critical information and control system infrastructures against attack from a variety of adversaries. Atkins received both Masters and Bachelors of Science degrees in Computer Engineering from the University of Missouri–Rolla, now the Missouri University of Science and Technology, in 2007 and 2005, respectively. His research interests include wireless communications systems, communications protocol analysis, embedded systems design, and reverse engineering.

    Update: The slides from the presentation are now available in both pdf and ppt. Comments related to the scenarios we went through were NOT exported into the PDF, so if you’re looking for all that good stuff you’re gonna have to grab the powerpoint.

    Capture the Flag Tools Recap

    posted January 27th, 2010

    If you didn’t make it to tonight’s meeting, or just want more information about the tools we covered, we have you covered. Below you’ll find what we covered and links for more information.

    Netcat
    Netcat is a utility included with almost every Linux distribution which allows users to make connections and send data over the network.

    To run Netcat as a server (listen for connections)
    :~$ nc -l -p [port]
    To send data to a host with Netcat
    :~$ nc [hostname] [port]

    Netcat itself is not available for Windows, but Ncat, an improved version of Netcat, is available along with Nmap. You can find more information about Ncat here.

    Nmap
    Nmap is a “network mapper” tool which can be used to discover hosts which are responding on a network and discover what services are available on those hosts. Versions for Linux, Mac, and Windows and documentation are available from the Nmap homepage.

    To discover hosts on a subnet
    :~$ nmap -sP [address range]
    Address ranges may be given in a variety of styles outlined in the documentation.
    To scan a host for active service versions and operating system
    # nmap -sV -O [host address]

    Wireshark
    Wireshark is a network packet sniffer which can be used to analyze captured network traffic. It may be used to inspect individual packets or reconstruct streams of data sent over the network. The tool is available for Linux, Mac, and Windows. Download and usage information can be found at Wireshark’s homepage, http://wireshark.org.

    Aircrack
    Aircrack-ng has grown into a suite of tools used to audit wireless network security. The set of tools was built for Linux, and, while there is a Windows port, most suggest that you use a Linux LiveCD to run Aircrack. The suite is available on the BackTrack Linux LiveCD distribution.

    The example given during the meeting was based on the Simple WEP Crack tutorial on the Aircrack-ng site.
