To state the obvious (as I tend to do), we all have too much to protect. No one gets through their list every day, which means perhaps the most critical skill for any professional is the ability to prioritize. We’ve got to focus on the issues that present the most significant risk to the organization (whatever you mean by risk) and act accordingly. I have’t explicitly said it, but the key to network security fundamentals is figuring out how to prioritize. And to be clear, though I’m specifically talking about network security in this series, the tactics
As a security practitioner, it has always been difficult to select the ‘right’ product. You (kind of) know what problem needs to be solved, yet you often don’t have any idea how any particular product will work and scale in your production environment. Sometimes it is difficult to identify the right vendors to bring in for an evaluation. Even when you do, no number of vendor meetings, SE demos, or proof of concept installations can tell you what you need to know. So it’s really about assembling a number of data points and trying to do your homework
You may not know it, but lots of folks you know are zombies. It seems that life has beaten them down, and miraculously two weeks later they don’t say ‘hi’ – they just give you a blank stare and grin as the spittle drips out of the corners of their mouths. Yup, a sure sign they’ve been to see Dr. Feelgood, who heard for an hour how hard their lives are, and as opposed to helping to deal with the pain, they got their friends Prozac, Lexapro, and Zoloft numb it. These billion dollar drugs build on the premise
In the last Network Security Fundamentals post, we talked about monitoring (almost) everything and how that drives a data/log aggregation and collection strategy. It’s great to have all that cool data, but now what? That brings up the ‘C word’ of security: correlation. Most security professionals have tried and failed to get sufficient value from correlation relative to the cost, complexity, and effort involved in deploying the technology. Understandably, trepidation and skepticism surface any time you bring up the idea of real-time analysis of security data. As usual, it comes back to a problem with management of expectations.
It seems I’ve been preoccupied lately with telling all of you about the things you shouldn’t do anymore. Between blowing away firewall rules and killing security technologies, I guess I’ve become that guy. Now get off my lawn! But why stop now – I’m on a roll. This week, let’s take on another common practice that ends up being an extraordinarily bad idea – running user devices with administrator access. Let’s slay that sacred cow. Once again, most of you security folks with any kind of kung fu are already here. You’d certainly not let
I tend to be master of the obvious. Part of that is overcoming my own lack of cranial horsepower (especially when I hang out with serious security rock stars), but another part is the reality that we need someone to remind us of the things we should be doing. Work gets busy, shiny objects beckon, and the simple blocking and tackling falls by the wayside. And it’s the simple stuff that kills us, as evidenced once again by the latest data breach study from TrustWave. Over the past couple months, we’ve written a bunch of times about the
Good Morning: I was at dinner over the weekend with a few buddies of mine, and one of my friends asked (again) which AV package is best for him. It seems a few of my friends know I do security stuff and inevitably that means when they do something stupid, I get the call. This guy’s wife contracted one of the various Facebook viruses about a month ago and his machine still wasn’t working correctly. Right, it was slow and sluggish and just didn’t seem like it used to be. I delivered the bad news that he
As we continue on our journey through the fundamentals of network security, the idea of network monitoring must be integral to any discussion. Why? Because we don’t know where the next attack is coming, so we need to get better at compressing the window between successful attack and detection, which then drives remediation activities. It’s a concept I coined back at Security Incite in 2006 called React Faster, which Rich subsequently improved upon by advocating Reacting Faster and Better. React Faster (and better) I’ve written extensively on the concept of React Faster, so here’s a quick description
(Update: Based on a comment, I added some caveats regarding business critical applications.) Since I’m getting my coverage of Network and Endpoint Security, as well as Security Management, off the ground, I’ll be documenting a lot of fundamentals. The research library is bare from the perspective of infrastructure content, so I need to build that up, one post at a time. As we start talking about the fundamentals of network security, we’ll first zero in on the perimeter of your network. The Internet-facing devices accessible by the bad guys, and usually one of the prevalent attack vectors.
Good Morning: Maybe it’s the hard-wired pessimist in me, but I never thought I’d live a long life. I know that’s kind of weird to think about, but with my family history of health badness (lots of the Big C), I didn’t give myself much of a chance. At the time, I must have forgotten that 3 out of my 4 grandparents lived past 85, and my paternal grandma is over 100 now (yes, still alive). But when considering your own mortality, logic doesn’t come into play. I also think my lifestyle made me think about my life expectancy. 3
