-    The second lecture of our security and privacy series. By undergraduate student 
-    Eric Dong.
+    In this talk, I will discuss censorship firewalls used in countries such as 
+    China and Iran, and how to counteract them. The focus is on advanced 
+    application-layer and Deep Packet Inspection firewalls, and unexpected hurdles 
+    in overcoming censorship by these firewalls due to the need for very 
+    unconventional adversary models. Approaches of the privacy tool Tor, popular 
+    proprietary freeware Ultrasurf and Freegate, payware VPNs, and my own 
+    experimental Kirisurf project are examined, where strengths and difficulties 
+    with each system are noted.</p>

-    The first lecture of our security and privacy series. By PhD student Sarah 
-    Harvey. 
+    Recent media coverage has brought to light the presence of various government
+    agencies' surveillance programs, along with the possible interference of
+    governments in the establishment and development of standards and software.
+    This brings to question of just how much we need to be concerned about the
+    security and privacy of our information.</p>
+    
+    <p>In this talk we will discuss what all this means in technological and social
+    contexts, examine the status quo, and consider the long-standing implications.
+    This talk assumes no background knowledge of security or privacy, nor any
+    specific technical background. All students are welcome and encouraged to
+    attend.</p>
