Motivation

Security is a necessary component of any piece of software or hardware, whether it operate on a high or low level, or used for commercial or personal use.
Since there is no single solution to security problems, the best procedure is to implement a variety of defenses. Our goal in this topic is to present a variety of defenses to aid the audience in securing their systems and networks.
Feel free to join our dedicated mailing list to ask your questions about this topic..

Subtopics

System Security : this subtopic aims at analysing problems and solutions at the system layer, through the kernel at a very low level.
Network Security : this subtopic deals with network security by going from problems like rerouting attacks or deny of service, to some kind of solutions like firewalls and VPN.
Applications Security : this one will help at knowing problems that exists at the software layer and how they could be avoid generally and with a given specific example of priviledge separation.
Intrusion Detection and Honeypots : here you'll find discussions about host and network based intrusion detection and how they may be bypassed, and also about still weird protections called honeypots.
PKI : here you'll find discussions about Public Key Infrastructure and the way it helps at securing exchanges between multiples people, processes, etc, with cool things like authentication, certificates...
Opened Round Table about Security and Opensource : this will end the Security Topic of the LSM2002 with an opened interactive discussion between the public and experts on current and future problems and solutions.

1. System Security

Bradley Spengler
spender@grsecurity.net
http://www.grsecurity.net/ Detection, Prevention, and Containment: A Study of grsecurity
An in-depth look into the motivations behind grsecurity.
Will cover a detailed examination of PaX: what it does, and how it does it.
Also covers a rationale on the implementations of important features of grsecurity, as well as an overview of its ACL system.
Performance of the ACL system and PaX will be discussed in detail.

Tim Yardley
liquid@dqc.org
http://nmedia.net/~liquid/ "Trusted Operating Systems: The Wave Of The Future?"
This discussion will cover the current security problems and why a standard system cannot solve those problems.
The basics behind trusted operating systems will be explained, including overviews of the different underlying security models.
After the basics are explained, further detail will be drawn in the form of benefits and drawbacks of each type of system. This will include discussion about the difficulties in the use of universal mandatory access control (MAC) vs non-universal MAC models.
Future evolution of these systems and their application will also be discussed. Further attention will be paid to future threats and ways to strengthen your systems against those threats now, if time allows.

An overview of various security systems for Linux: Linux Security Modules (LSM) for 2.5, LIDS, Medusa DS9, RSBAC, LOMAC, and SELinux.

http://www.citi.umich.edu/u/provos/systrace/ Systrace - Interactive Policy Generation for System Calls
Systrace enforces system call policies for applications by constraining the application's access to the system. The policy is generated interactively. Operations not covered by the policy raise an alarm and allow an user to refine the currently configured policy.
With systrace untrusted binary applications can be sandboxed. Their access to the system can be restricted almost arbitrarily. Sandboxing applications available only as binaries is only sensible as it is not possible to directly analyze what they are designed to do.

2. Network Security

Harald Welte laforge@gnumonks.org http://www.gnumonks.org/users/laforge/	Current netfilter/iptables development and our plans for kernel 2.5.x (failover, pkt_tables, nfnetlink, ...) Duration: 1 hour Audience: Developers
Harald Welte laforge@gnumonks.org http://www.gnumonks.org/users/laforge/	An advance netfilter/iptables presentation about the design and implementation Duration: 1.5-2 hours Audience: Advanced Admins, Developers
Cedric Blancher blancher@cartel-securite.fr	Switched network security : a fairy tale... Most network engineers think their network is sniff-proof because of their use of switches. The goal of this presentation is to demonstrate why switched networks are insecure, and to show some consequences that can be even worse than in non-switched environments. . Introduction : Layer 2 protocols, IP and ARP ; ethernet . Ethernet basics : technology, topology, segmentation . Hubs : consequences . Switches : goals, security issues, urban legends ;) . ARP protocol attacks : traffic redirection HOWTO . Consequences : sniffing, DoS, trafic capture, MITM... . Some ways and tools to prevent and detect ARP attacks . Other layer 2 protocols to fucs on : HSRP, VRRP, CDP, VTP, DTP, etc... A mini-demo of attacks presented below will be available during the speech.
Victor Vuillard victor.vuillard@utbm.fr	OpenBSD and some of it's interests : - Licences, goals and principles : differences between Linux and OpenBSD - ipf and pf : OpenBSD firewalling. - authpf : how to create dynamic firewall ? (for example to secure a gateway that connects a wireless network to the rest of the non-radio network) - ipsec implementation and quick example (connecting a Linux-FreeS/WAN and OpenBSD using isakmpd)
Sebastien Lacoste-Seris kaneda@securite.org Nicolas Fischbach nico@securite.org http://www.securite.org/	Security in large Service Provider networks This talk will focus on the usage and integration of free/opensource tools to increase the security of a large IP network. They will describe some setups (for example : (D)DoS detection based on Netflow data sent to a cflow gatherer, stored in RRDtool files, analyzed with Flowscan and reported using Apache::Embperl). They will also discuss the pros and cons of such tools (for example IDSes in a dial-up/hosting environment).
Hervé Eychenne herve.eychenne@kdx.fr http://www.wallfire.org/	WallFire: a multi-platform firewall admnistration toolkit. The goal of the WallFire project is to build a very general and modular firewalling application based on Netfilter or any kind of low-level framework. It will enable to manage every aspect of a firewall administration, from configuration to monitoring, intrusion detection, etc...

3. Applications Security

Marius Aamodt Eriksen marius@citi.umich.edu http://www.citi.umich.edu/u/marius/	Proxide Project. Network and applications security for instant messages, etc. Proxide is a context sensitive generic network filter. It relies on plugins to perform the operations of putting internet protocols into a common context, as well as to provide the filters that operate upon common context, the protocol plugin is then responsible for reassembling the message and sending it to the intended recipient...
Denis Ducamp Denis.Ducamp@hsc.fr http://www.hsc.fr/	How to design secure applications based on privilege separation What are the basic security functionalities under Unix needed to build privilege separation and how to use them to design more secure applications
Frederic Raynal pappy@miscmag.com http://minimum.inria.fr/~raynal/	(In)Secure Programming : - escape shells - memory management (stack, heap...) and function calls - buffer overflows in the stack - buffer overflows in the "low" sections (heap, bss, data) - format bugs [- malloc's tricks ?] [- race conditions ?]

4. Intrusion detection and Honeypots

Niels Provos provos@citi.umich.edu http://www.citi.umich.edu/u/provos/honeyd/	Virtual honeypots with honeyd Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses - he has tested up to 65536 - on a LAN for network simulation.
