Beware of ws-xmlrpc library in your Java App

Apache XML-RPC is a XML-RPC library for Java. XML-RPC is a protocol for making remote procedure call via HTTP with the help of XML. Apache XML-RPC can be used on the client's side to make XML-RPC calls as well as on the server's side to expose some functionality via XML-RPC. Now ws-xmlrpc library is not supported by Apache. Last version is 3.1.3 which was released in 2013. However, many applications still use ws-xmlrpc library. Among them are Apache Continuum and Apache Archiva.

Github Engineering: SYN Flood Mitigation with synsanity

In an effort to reduce the impact of these attacks, we began work on a series of additional mitigation strategies and systems to better prepare us for a future attack of a similar nature. Today we're sharing our mitigation for one of the attacks we received: synsanity, a SYN flood DDoS mitigation module for Linux 3.x.

The Value of a Hacked Company

Most organizations only grow in security maturity the hard way -- that is, from the intense learning that takes place in the wake of a costly data breach. That may be because so few company leaders really grasp the centrality of computer and network security to the organizations overall goals and productivity, and fewer still have taken an honest inventory of what may be at stake in the event that these assets are compromised.
