[Qemu-devel] Argos: qemu-based honeypot
All, I am happy to announce the first release of Argos: a full system emulator (based on Qemu) that detects attempts to compromise the system. It is meant to be used in a honeypot and offers full-system protection, i.e., it protects the kernel and all applications running on top. Argos is hosted at: http://www.few.vu.nl/~porto/argos Note: while there is a full installation guide and info on how to run Argos, there is currently little additional documentation. We will add this as soon as possible. People interested in details should contact us for a technical report (the paper is currently under submission, so we cannot stick it on the website yet). Cheers, HJB Here is the blurb from the website. Argos is a /full/ and /secure/ system emulator designed for use in Honeypots. It is based on QEMU http://fabrice.bellard.free.fr/qemu/, an open source processor emulator that uses dynamic translation to achieve a fairly good emulation speed. We have extended QEMU to enable it to detect remote attempts to compromise the emulated guest operating system. Using dynamic taint analysis Argos tracks network data throughout the processor's execution and detects any attempts to use them in a malicious way. When an attack is detected the memory footprint of the attack is logged and the emulators exits. Argos is the first step to create a framework that will use /next generation honeypots/ to automatically identify and produce remedies for zero-day worms, and other similar attacks. /Next generation honeypots/ should not require that the honeypot's IP address remains un-advertised. On the contrary, it should attempt to publicise its services and even actively generate traffic. In former honeypots this was often impossible, because malevolent and benevolent traffic could not be distinguished. Since Argos is explicitly signaling each possibly successful exploit attempt, we are now able to differentiate malicious attacks and innocuous traffic. --- Dr. Herbert Bos Vrije Universiteit Amsterdam www.cs.vu.nl/~herbertb ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
Re: [Qemu-devel] [patch] Poor user-net performance.
On Sun, Dec 18, 2005 at 11:28:27PM +, Paul Brook wrote: Dan mentioned he was seeing very poor network performance when using user-net. It turns out this is because packets were getting dropped (the NIC buffers were full), and the slirp code doesn't throttle properly when this occurs. You end up with a bunch of packets getting sent to the guest, half of which get dropped, then a delay until slirp retransmits. This is much more noticeable on Arm because the NIC only has a small memory buffer. Teaching the slirp code how to do tcp backoff/window scaling is probably a fair amount of work. The easy alternative is to throttle the slirp output when we know the card's buffers are full. slirp has a convenient hook for this, so it's a matter of adding the hooks to the hardware emulation. This increases arm user-net performance from painfully slow (~200kbit) to guest CPU bound (~20Mbit). Hmm is the patch supposed to work for i386 guests too? I get no dhcp response and network unreachable when i try to ssh to the host from the guest after manually ifconfig'ing, seem like the ne2k doesn't receive any packets. (FreeBSD/i386 host, linux i386 guest - kanotix livecd iso). The same works normally without the patch. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
