A common situation we come across is one of allowing people secure filecopying to a system, but without giving full shell access to the system at the same time.
We've long since recommended scponly, which is a great solution to this very problem. scponly is a shell for UNIX systems that allows just that - scp/sftp only, with no access to an actual shell.
Today we were implementing this on a Solaris 10 x86 system, but couldn't find a Sun package to do it - so we compiled it up and rolled our own package
The version we've built was compiled with Sun Studio 11, complete with optimisations for speed. It installs to /opt/tsis/bin. If you're after scponly for Solaris x86, feel free to download and use our package. If you want the package for Sparc just drop us an email, and we'll probably be able to wrap it up for you pretty quickly (for free :-))

The magnificent 7
Here at 360is we've been using some common tools for a number of years - because, despite looking elsewhere, these tools have proven again and again to be great at the jobs they set out to do.
So we've picked out our most frequently recommended pieces of software and investigated them in more detail - the people behind them, how they came about, and what makes them worth using.
The seven are: nmap, syslog-ng, tcp-wrappers, ssh, sudo, postfix and rsync.

The Growing Trend of Security Whitelists
My esteemed colleague here at 360is, Nick Hutton, has written a great article about security whitelisting.
In case you're not familiar with the phrase, security whitelisting takes the opposite (and some would say far more sensible) approach to security than we do today.
Go have a read of the article to get in the know.

Looking for some Sunshine
Here at 360is we're big fans of UNIX. Predominantly we use Sun Solaris, with some FreeBSD and Linux for specific tasks. Our desktop of choice is Mac OS X - founded on UNIX. We prefer UNIX over Microsoft's offering because of the flexibility and accountability of the systems. You can always get to the bottom of a problem.
There are plenty of other reasons too, but here's a good enough reason alone to be considering Sun - the mentality of their CEO, Jonathan Schwartz...
Free advice for the litigious
In a time when some vendors are intent on keeping their share of the market by peddling FUD (fear, uncertainty and doubt) Sun are going from strength to strength by doing what they do best, and going about it in a professional, congenial, way.
We share Schwartz's attitude - we don't like to sell security by using FUD either (the traditional way to make somebody invest in security - scare them!). Security is a vital part of any business, and building your infrastructure on UNIX is a really good start. We'll be publishing our Solaris 10 hardening guide soon, along with some information about our favourite open source tools for looking after your business.

Methods and tactics for avoiding failure in large SEM implementations
Most of the work we undertake is a mixture of penetration testing, audits, post-incident clean-up, and secure infrastructure deployment. However, over the last 12 months we have repeatedly been called upon to rescue failed or failing projects around the area of Security Event and Information Management (SEM/SIEM). We've collected all the knowledge gained in these "rescue projects" and have packaged it in a short whitepaper for download. For those of you that like to know what they have been given before it is unwrapped, here is the abstract:
"Many will be familiar with the English proverb “more haste, less speed”, or to put it another way, finishing a task quickly is not about rushing. This advice could have been tailor made for complex IT projects. In this paper we learn how to mitigate some of the risks and reduce the costs associated with implementation of Security Event Management systems, arguably among the most complex and highest profile information security projects undertaken today."
If you are considering one of these systems then we think you should spend 9 pages and 15 minutes in this vendor-free hype-free document.
