Anyone with appropriate skills may contribute, with commit rights being awarded on merit and De Raadt acting as coordinator. Maintenance patches for supported releases may be applied manually or by updating the system against the patch branch of the CVS repository for that release. The generic OpenBSD kernel provided by default is strongly recommended for end users, in contrast to operating systems that recommend user kernel customization. Ports are generally not subject to the same continuous auditing as the base system due to lack of manpower.

Binary packages are built centrally from the ports tree for each architecture. This process is applied for the current version, for each supported release, and for each snapshot. Administrators are recommended to use the package mechanism rather than build the package from the ports tree, unless they need to perform their own source changes. For example, the swap space is divided into small sections and each section is encrypted with its own key, ensuring that sensitive data does not leak into an insecure part of the system.

For example, PIDs are created and associated randomly to processes; the bind system call uses random port numbers ; files are created with random inode numbers; and IP datagrams have random identifiers.

The OpenBSD policy on openness extends to hardware documentation: in the slides for a December presentation, De Raadt explained that without it "developers often make mistakes writing drivers", and pointed out that "the [oh my god, I got it to work] rush is harder to achieve, and some developers just give up. The project attempts to "maintain the spirit of the original Berkeley Unix copyrights ," which permitted a "relatively un-encumbered Unix source distribution.

To ensure that all licenses were properly adhered to, an attempt was made to contact all the relevant copyright holders: some pieces of code were removed, many were replaced, and others, such as the multicast routing tools mrinfo and map-mbone, were relicensed so that OpenBSD could continue to use them.

At the time, Bernstein requested that all modified versions of his code be approved by him prior to redistribution, a requirement to which OpenBSD developers were unwilling to devote time or effort.

Obviously, that has not been a lot of money. However, De Raadt expressed concern about the asymmetry of funding: "I think that contributions should have come first from the vendors, secondly from the corporate users, and thirdly from individual users.

But the response has been almost entirely the opposite, with almost a to-1 dollar ratio in favor of the little people. Thanks a lot, little people! OpenBSD provides a package management system for easy installation and management of programs which are not part of the base operating system.

On OpenBSD, the source of packages is the ports system, a collection of Makefiles and other infrastructure required to create packages. In OpenBSD, the ports and base operating system are developed and released together for each version: this means that the ports or packages released with, for example, 4. Green planned to create a full daemon, including head and body, but only the head was completed in time for OpenBSD 2. The body as well as pitchfork and tail was completed for OpenBSD 2.

The promotional material of early OpenBSD releases did not have a cohesive theme or design, but later the CD-ROMs, release songs, posters and tee-shirts for each release have been produced with a single style and theme, sometimes contributed to by Ty Semaka of the Plaid Tongued Devils.

Network Associates Ships CyberCop Sting

CyberCop Sting is a component of the CyberCop intrusion protection software family which also includes CyberCop Monitor, a real-time intrusion detection application that monitors critical systems and networks for signs of attack and CyberCop Scanner, a network vulnerability scanner. CyberCop Sting allows IS managers to silently monitor suspicious activity on their corporate network and identify potential problems. It operates by creating a series of fictitious corporate systems on a specially outfitted server that combines moderate security protection with sophisticated monitoring technology. Each virtual network device has a real IP address and can receive and send genuine-looking packets from and to the larger network environment. Each virtual network node can also run simulated daemons, such as finger and FTP, to further emulate the activity of a genuine system and avoid suspicion by would-be intruders. Network Associates, Inc. CyberCop Sting provides a number of benefits for security administrators, including: Detection of suspicious activity inside network; Log files serve to alert administrators to potential attackers prying into reserved areas.
