1. Biologically Based Approaches to Computer Security
Our software infrastructure confronts a situation increasingly similar to the challenges faced by living organisms in a biological ecosystem. Highly dynamic, complex, and hostile environments are placing new demands on our computational infrastructure. Biological design principles can potentially change the way we engineer, maintain, and evolve large dynamic software infrastructures. Examples of such principles include: adaptability, homeostasis, redundancy, and diversity.

The talk will illustrate how biological design principles are providing new insights and approaches in the field of computer security and privacy. The talk will describe results in intrusion detection, automated diversity and privacy-enhancing data representations.

2. Technological Networks: From Empirical Laws to Theory
Technological networks are essential to modern society, and the security of these networks depends in large part on their connectivity and dynamics. How do these properties scale with network size? Are there general principles underlying the growth and structure of technological networks? If such organizing principles exist, what do they tell us about security, efficiency, and stability as the networks grow? The talk explores these questions in the context of three example computational networks: Social networks on the Internet, the Border Gateway Protocol, and clock tree networks on computer chips.

Talk I:
Title: Towards an Automatic Immune System for Internet Health
Just as any living organism is constantly threatened by rapacious pathogens, the Internet is continuously threatened by cyber pathogens (e.g., Internet worms, botnets, spyware), which have caused billions of dollars of estimated annual financial losses. Just as any living organism needs a strong immune system to survive and be healthy, so does the Internet. My research group has devised various techniques (and systems) towards this goal. In this talk, I will give one such example---Sting, an automatic immune system against Internet worms. Sting can automatically and accurately detect new exploits even for previously unknown vulnerabilities, and generate effective anti-bodies (including signatures and hardened binaries) to protect vulnerable hosts and networks from further attacks; with proven properties, and all just within minutes or even seconds. I will then offer a glimpse of some of our other results in the area, including automatic dissection of malicious binaries to discover hidden behaviors and threats.
-------------------------------------------------------------------
Talk II
Title: Privacy-preserving search, set operations, and beyond
In this talk, I will describe our recent work on designing practical cryptographic primitives and security mechanisms to enable secure and privacy-preserving information aggregation and processing. As one example, I will talk about searching on encrypted data, in particular, how to enable keyword and range queries on encrypted data without revealing any other information about the content of the data. As another example, I will describe our new approach to enable private stream search, and as an application, a private version of the Google News Service, where users obtain news feeds that match their keyword queries from the servers without the servers knowing what keywords the user is searching for or which news articles actually match the user's query. Finally, I will describe our algorithm to enable privacy-preserving set operations, where only the result of the set operations will be revealed and no additional information about users' private input sets will be leaked. Set operations are among the most common primitives in database operations; our mechanism provides the first efficient privacy-preserving solution for a broad spectrum of different set operations and enables important applications in different areas such as medical system privacy and privacy in distributed network monitoring systems. I will conclude with future work and applications and some intriguing open problems.
