I was reading one of RSnake’s posts on how our security devolves to the lowest common denominator because we can’t break IT – which means we can’t make changes to systems, applications, and endpoints in order to protect them. He was talking specifically about the browser, but it got me thinking a bit bigger: when/if it’s OK to break IT. To clarify, by breaking IT , I mean changing the user experience adversely in some way to more effectively protect critical data/information.
Way back when I converted Securosis from a blog into a company, my very first paper was (no surprise) Understanding and Selecting a DLP Solution.
Facebook is for old people. Facebook will ultimately make us more secure.
I have learned these two important lessons over the last few weeks. Saying Facebook is for old people is not like saying it’s dead – far from it. But every time I talk computers with people 10-15 years older than me, all they do is talk about Facebook. They love it! They can’t believe they found high school acquaintances they have not seen for 30+ years. They love the convenience of keeping tabs on family and friends from…
In Incident Response Fundamentals: Introduction we talked about the philosophical underpinnings of our approach and how you need to look at stuff before, during, and after an attack. Regardless of where in the attack lifecycle you end up, there is a common requirement: for data. As we mentioned, you only get one opportunity to capture the data, and then it’s gone. So in order to react faster and better in your environment, you will need lots of data.
One of my favorite sayings is “Don’t ask the question if you don’t want the answer.” Of course, when I say answer , what I really mean is opinion. It makes no difference what we are talking about, I probably have an opinion. In fact, a big part of my job is to have opinions and share them with however will listen (and even some who won’t). But to have opinions means you need to judge.
What? A research report on enterprise firewalls. Really? Most folks figure firewalls have evolved about as much over the last 5 years as ant traps. They’re wrong, of course, but people think of firewalls as old, static, and generally uninteresting. But this is unfounded. Firewalls continue to evolve, and their new capabilities can and should impact your perimeter architecture and firewall selection process. That doesn’t mean we will be advocating yet another rip and replace job at the perimeter…
My session for the Atlanta BSides conference was about what I expected in 2011. I might as well have thrown a dart at the wall. But the exercise got me thinking about the newest attacks (like Stuxnet) and the realization of how state-sponsored attackers have penetrated our networks with impunity. Clearly we have to shake up the status quo in order to keep up.
Over the past year, as an industry we have come to realize that we are dealing with different adversaries using different attack techniques with different goals. Yes, the folks looking for financial gain by compromising devices are still out there. But add a well-funded, potentially state-sponsored, persistent and patient adversary to the mix, and we need to draw a new conclusion. Basically, we now must assume our networks and systems are compromised. That is a tough realization, but any other…
As we have discussed through this series, monitoring additional data types can extend the capabilities of SIEM in a number of different ways. But you have lots of options for which direction to go. So the real question is: where do you start? Clearly you are not going to start monitoring all of these data types at once, particularly because most forms require some integration work on your part – often a great deal. Honestly, there are no hard and fast answers on where to start, or what type of…
So far in the Monitoring up the Stack series, we have focused on a number of additional data types and analysis techniques that extend security monitoring to gain a deeper and better perspective of what’s happening. We have been looking at the added value that is all good, but we all know there is no free lunch. So now let’s look at some of the problems, challenges, and extra work that come along with deeper monitoring goodness. We know most of you who have labored with scalability and…
