The OpenBSD Invisible Firewall
White Paper An option that many people are unaware of, and therefore can never consider, is the OpenBSD invisible, firewall. OpenBSD is able, without any kernel modification, to set up a bridge between two network interfaces. [10 Jul 2008]
Secure Programmer: Countering Buffer Overflows
White Paper It then shows various ways to counter buffer overflows in C/C++ programs, both statically-sized approaches (such as the standard C library and OpenBSD/strlcpy solution) and dynamically-sized solutions, as well as some tools to help you. [03 Jul 2008]
Delivering Signals for Fun and Profit
White Paper Few systems have extensive documentation of signal-safe calls - that includes OpenBSD, Solaris, etc. This paper is an attempt to discuss, demonstrate and analyze the security impact of popular design and coding practices used when implementing... [03 Jul 2008]
Validation of Simulated Real World TCP Stacks
White Paper The Network Simulation Cradle makes real world TCP implementations available to ns-2: Linux, FreeBSD and OpenBSD can all be simulated as easily as using the original simplified models. The TCP models in the network simulator ns-2 are widely used in... [09 Jan 2008]
Measured Comparative Performance of TCP Stacks
White Paper The authors have found that there are significant differences between the TCP implementations found in Linux, FreeBSD, OpenBSD and Windows XP. Implementations of a protocol vary in many respects, including how well they perform. [09 Jan 2008]
Embedding Covert Channels Into TCP/IP
White Paper Finally, the paper describes reversible transforms that map block cipher output onto TCP ISNs, indistinguishable from those generated by Linux and OpenBSD. It is commonly believed that steganography within TCP/IP is easily achieved by embedding... [20 Dec 2007]
Mastering FreeBSD and OpenBSD Security: The Big Picture
White Paper Security is hard. People have heard this phrase as a rationale for insecure systems and poor administrative practices. What's worse, administrators seem to have different ideas about what "Security" entails. [24 Oct 2007]
A Study of Initialization in Linux and OpenBSD
White Paper Specifically, the ways in which the OpenBSD and Linux operating systems handle initialization are dissected. The code that initializes a system can be notoriously difficult to understand. In secure systems, initialization is critical for... [03 Apr 2007]
Microsoft beefs up Vista's buffer
News Several open source security systems use it already, including OpenBSD, and the PaX and Exec Shield patches for Linux. Windows Vista Beta 2, released last week, includes a new security feature designed to protect against buffer overrun exploits. [02 Jun 2006]
Open source bugs threaten digital signatures
News The software, a free replacement for the Pretty Good Privacy cryptographic technology, ships with many open source operating systems such as FreeBSD, OpenBSD and many Linux distributions. A pair of security bugs in cryptography software could allow... [13 Mar 2006]
US government funds open source bug hunt
News The list of open-source projects that Stanford and Coverity plan to check for security bugs includes Apache, BIND, Ethereal, KDE, Linux, Firefox, FreeBSD, OpenBSD, OpenSSL and MySQL, Coverity said. The US Department of Homeland Security is... [11 Jan 2006]
Linux is 'terrible' say open source rivals
News The founder of the OpenBSD operating system has criticised the quality of Linux software claiming that it is full of code hacks, according to reports. Theo de Raadt, the founder and lead developer of the open source operating system OpenBSD, said... [20 Jun 2005]
Open source rival attacks 'terrible' Linux
The founder of the OpenBSD operating system has criticised the quality of Linux software claiming that it is full of code hacks, according to reports. Theo de Raadt, the founder and lead developer of the open source operating system OpenBSD, said... [17 Jun 2005]
NetBSD makes cash plea
Simon pointed out while NetBSD sister projects like OpenBSD and FreeBSD had received "tens or even hundreds of thousands of dollars" in donations, his own project had been a little embarassed to ask its users for contributions. [14 Jun 2005]
Security guru wants access to bug databases
One of Anderson's research students, Andy Ozment, has already done research using empirical data on bugs found in the open source operating system OpenBSD between 1997 and 2000. Security expert Ross Anderson has called for empirical research to be... [21 Apr 2005]
