  • OPENBSD HARDWARE SENSORS FRAMEWORK a Unified and Ready-To-Use System for Hassle-Ee Hardware Monitoring
    OPENBSD HARDWARE SENSORS FRAMEWORK A unified and ready-to-use system for hassle-ee hardware monitoring. Constantine A. Murenin and Raouf Boutaba University of Waterloo AsiaBSDCon 2009 — 12–15 March 2009 — Tokyo, Japan Abstract In this paper, we will discuss the origin, history, design guidelines, API and the device drivers of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in the base system and the ports tree, is utilised by over 70 drivers, and is considered to be a distinctive and ready-to-use feature that sets OpenBSD apart from many other operating systems, and in its root is inseparable from the OpenBSD experience. 1.

  • Cryptanalysis of the Random Number Generator of the Windows Operating System
    Cryptanalysis of the Random Number Generator of the Windows Operating System Leo Dorrendorf School of Engineering and Computer Science The Hebrew University of Jerusalem 91904 Jerusalem, Israel [email protected] Zvi Gutterman Benny Pinkas¤ School of Engineering and Computer Science Department of Computer Science The Hebrew University of Jerusalem University of Haifa 91904 Jerusalem, Israel 31905 Haifa, Israel [email protected] [email protected] November 4, 2007 Abstract The pseudo-random number generator (PRNG) used by the Windows operating system is the most commonly used PRNG. The pseudo-randomness of the output of this generator is crucial for the security of almost any application running in Windows. Nevertheless, its exact algorithm was never published. We examined the binary code of a distribution of Windows 2000, which is still the second most popular operating system after Windows XP. (This investigation was done without any help from Microsoft.) We reconstructed, for the ¯rst time, the algorithm used by the pseudo- random number generator (namely, the function CryptGenRandom). We analyzed the security of the algorithm and found a non-trivial attack: given the internal state of the generator, the previous state can be computed in O(223) work (this is an attack on the forward-security of the generator, an O(1) attack on backward security is trivial). The attack on forward-security demonstrates that the design of the generator is flawed, since it is well known how to prevent such attacks. We also analyzed the way in which the generator is run by the operating system, and found that it ampli¯es the e®ect of the attacks: The generator is run in user mode rather than in kernel mode, and therefore it is easy to access its state even without administrator privileges.

  • Openbsd: Firewall Ridondanti Con CARP E Pfsync Chris Gamboni CISSP [email protected] Tilug.Ch, Bellinzona, 9 Aprile 2005 Cos'è Openbsd ?
    OpenBSD: Firewall ridondanti con CARP e pfsync Chris Gamboni CISSP [email protected] TiLug.ch, Bellinzona, 9 aprile 2005 Cos'è OpenBSD ? ● OpenBSD: – Nasce da un fork di netbsd nel 1995 – Secure by default (1 remote exploit in 8 anni) – Progetto basato in Canada, nessuna restrizione sull’esportazione di crittografia – Una release ogni 6 mesi (3.7 al 1.6.2005) – Si finanzia con la vendita di CD e di gadgets – Progetti collegati: OpenSSH, OpenNTPd, OpenBGPd, OpenOSPFd, etc… Alta disponibilità: CARP e pfsync ● Il firewall è un single point of failure – Quando il firewall è fermo nessuno accede ad internet, gli e-mail sono bloccati, ecc… – Non si può fermare il firewall per aggiornarlo ● OpenBSD, dalla versione 3.5, offre CARP e pfsync che permettono di avere firewalls in parallelo. Quando un firewall si ferma, il firewall di backup ne assume l’identità in modo trasparente. CARP (1) ● Common Address Redundancy Protocol: è il protocollo che si occupa di gestire il failover a livello 2 ed a livello 3. ● Ogni gruppo CARP possiede: – Un indirizzo MAC virtuale – Un indirizzo IP virtuale – Una password CARP (2) ● Ogni interfaccia CARP può avere 3 stati: MASTER, BACKUP e INIT (ifconfig) ● Il master manda messaggi Multicast (224.0.0.18) usando il protocollo IP 112 ● La frequenza di invio dei messaggi è configurabile (default = 1 sec) ● Chi invia messaggi più frequentemente diventa master CARP (3) ● CARP funziona sia con IPv4 sia con IPv6 ● CARP ha anche una funzione arp-balance che può servire per load-balancing, ma solo nella rete locale. ● CARP spedisce messaggi cifrati con SHA-1 HMAC ● CARP, a differenza di HSRP e VRRP, è esente da licenze e brevetti.

  • Mengenal Sistim Operasi *BSD
    Mengenal Sistim Operasi *BSD Ada banyak sekali tulisan-tulisan yang membahas tentang BSD, baik tulisan mengenai sejarah, system administrasi, sampai penggunaan BSD kepada end-user sebagai desktop. Tulisan ini memperkenalkan BSD sebagai alternatif lain dari Linux untuk memenuhi kebutuhan akan UNIX-like operating system di Indonesia. Dalam tulisan ini pula, dibahas mengenai beberapa hal yang membedakan antara Linux dan BSD, namun tidak memutuskan mana yang paling baik, karena untuk menentukan mana operating system yang paling baik digunakan adalah Anda sendiri. Daftar Isi 1. Sejarah 2. Distribusi Varian BSD 3. Model Pengembangan 4. Integrasi System 5. Software-software di BSD 6. System Administrasi 7. File System 8. Lain-lain 9. Kesimpulan Sejarah Hampir semua orang telah mendengar Linux saat ini. Namun apa itu BSD? BSD adalah singkatan dari Berkeley Software Distribution. BSD pertama kali dibangun dan dikembangkan oleh Computer System Research Group (CSRG) di University of California at Berkeley (UCB), BSD pertama kali keluar pada akhir 1977 sebagai paket tambahan dan patch dari AT&T UNIX version 6, yang mana waktu itu beroperasi pada mesin PDP-11 minicomputer. BSD pada akhirnya banyak memberikan kontribusi berharga pada pengembangan UNIX secara umum. Ada banyak fitur yang pertama kali diperkenalkan oleh BSD dan beberapa diadopsi dari AT&T dan vendor-vendor lainnya. BSD dibuat, dikembangkan, dan digunakan secara BEBAS sebagai perlawanan terhadap lisensi UNIX yang dimiliki oleh AT&T dan oleh karena itu BSD mempunyai lisensi tersendiri yang memungkinkan setiap orang bebas melakukan pengembangan, dan menggunakan source code BSD. Pada tahun 1993, 4.4BSD dirilis sebagai sebuah Operating System yang utuh. Untuk sejarah lengkap BSD di CSRG, mulai sejarah dari jaman kuda, motivasi orang-orang yang pertama kali mengerjakannya, sampai perseteruan lisensi dan hak cipta dengan AT&T, saya mereferensikan Anda untuk membaca tulisan yang dibuat oleh Kirk McKusick, “Twenty Years of Berkeley Unix“.

  • UNIX History Page 1 Tuesday, December 10, 2002 7:02 PM
    UNIX History Page 1 Tuesday, December 10, 2002 7:02 PM CHAPTER 1 UNIX Evolution and Standardization This chapter introduces UNIX from a historical perspective, showing how the various UNIX versions have evolved over the years since the very first implementation in 1969 to the present day. The chapter also traces the history of the different attempts at standardization that have produced widely adopted standards such as POSIX and the Single UNIX Specification. The material presented here is not intended to document all of the UNIX variants, but rather describes the early UNIX implementations along with those companies and bodies that have had a major impact on the direction and evolution of UNIX. A Brief Walk through Time There are numerous events in the computer industry that have occurred since UNIX started life as a small project in Bell Labs in 1969. UNIX history has been largely influenced by Bell Labs’ Research Editions of UNIX, AT&T’s System V UNIX, Berkeley’s Software Distribution (BSD), and Sun Microsystems’ SunOS and Solaris operating systems. The following list shows the major events that have happened throughout the history of UNIX. Later sections describe some of these events in more detail. 1 UNIX History Page 2 Tuesday, December 10, 2002 7:02 PM 2 UNIX Filesystems—Evolution, Design, and Implementation 1969. Development on UNIX starts in AT&T’s Bell Labs. 1971. 1st Edition UNIX is released. 1973. 4th Edition UNIX is released. This is the first version of UNIX that had the kernel written in C. 1974. Ken Thompson and Dennis Ritchie publish their classic paper, “The UNIX Timesharing System” [RITC74].
