This post is based on a recent article on the CIO.com site.
I have to say, when I read the title of the article, the cynic in me once again prevailed. And indeed there will be some cynicism and sarcasm in this article, so if that offends the reader, i would like to suggest other sources of information: those which do not accurately reflect the state of the information security industry. Unfortunately the truth is often accompanied by at least cynicism. Indeed, if I meet an IT professional who isn’t cynical and sarcastic, I do find it hard to trust them.
Near the end of the article there will be a quiz with a scammed prize offering, just to take the edge of the punishment of the endless “negativity” and abject non-MBA’edness.
“While organizations have been hot to virtualize their machine operations, that zeal hasn’t been transferred to their adoption of good security practices”. Well you see they’re two different things. Using VMs reduces power and physical space requirements. Note the word “physical” here and being physical, the benefits are easier to understand.
Physical implies something which takes physical form – a matter energy field. Decision makers are familiar with such energy fields. There are other examples in their lives such as tables, chairs, other people, walls, cars. Then there is information in electronic form – that’s a similar thing (also an energy field) but the hunter/gatherer in some of us doesn’t see it that way, and still as of 2013, the concept eludes many IT decision makers who have fought their way up through the ranks as a result of excellent performance in their IT careers (no – it’s not just because they have a MBA, or know the right people).
There is a concept at board level of insuring a building (another matter energy field) against damages from natural causes. But even when 80% of information assets are in electronic form, there is still a disconnect from the information. Come on chaps, we’ve been doing this for 20 years now!
Josh Corman recently tweeted “We depend on software just as much as steel and concrete, its just that software is infinitely more attack-able!”. Mr Corman felt the need to make this statement. Ok, like most other wise men in security, it was intended to boost his Klout score, but one does not achieve that by tweeting stuff that everybody already knows. I would trust someone like Mr Corman to know where the gaps are in the mental portfolios of IT decision makers.
Ok, so moving on…”Nearly half (42 percent) of the 346 administrators participating in the security vendor BeyondTrust‘s survey said they don’t use any security tools regularly as part of operating their virtual systems…”
What tools? You mean anti-virus and firewalls, or the latest heuristic HIDS box of shite? Call me business-friendly but I don’t want to see endless tools on end points, regardless of their function. So if they’re not using tools, is it not at this point good journalism to comment on what tools exactly? Personally I want to see a local firewall and the obligatory and increasingly less beneficial anti-virus (and i do not care as to where, who, whenceforth, or which one…preferably the one where the word “heuristic” is not used in the marketing drivel on the box). Now if you’re talking system hardening and utilizing built-in logging capability – great, that’s a different story, and worthy of a cuddly toy as a prize.
“Insecure practices when creating new virtual images is a systemic problem” – it is, but how many security problems can you really eradicate at build-time and be sure that the change won’t break an application or introduce some other problem. When practical IT-oriented security folk actually try to do this with skilled and experienced ops and devs, they realise that less than 50% of their policies can be implemented safely in a corporate build image. Other security changes need to be assessed on a per-application basis.
Forget VMs and clouds for a moment – 90%+ of firms are not rolling out effectively hardened build images for any platform. The information security world is still some way off with practices in the other VM field (Vulnerability Management).
“If an administrator clones a machine or rolls back a snapshot,”… “the security risks that those machines represent are bubbled up to the administrator, and they can make decisions as to whether they should be powered on, off or left in state.”
Ok, so “the security risks that those machines represent are bubbled up to the administrator”!!?? [Double-take] Really? Ok, this whole security thing really can be automated then? In that case, every platform should be installed as a VM managed under VMware vCenter with the BeyondTrust plugin. A tab that can show us our risks? There has to be a distinction between vulnerability and risk here, because they are two quite different things. No but seriously, I would want to know how those vulnerabilities are detected because to date the information security industry still doesn’t have an accurate way to do this for some platforms.
Another quote: “It’s pretty clear that virtualization has ripped up operational practices and that security lags woefully behind the operational practice of managing the virtual infrastructure,”. I would edit that and just the two words “security” and “lags”. What with visualized stuff being a subset of the full spectrum of play things and all.
“Making matters worse is that traditional security tools don’t work very well in virtual environments”. In this case i would leave remaining five words. A Kenwood Food Mixer goes to the person who can guess which ones those are. See? Who said security isn’t fun?
“System operators believe that somehow virtualization provides their environments with security not found in the world of physical machines”. Now we’re going Twilight Zone. We’ve been discussing the inter-cluster sized gap between the physical world and electronic information in this article, and now we have this? Segmentation fault, core dumped.
Anyway – virtualization does increase security in some cases. It depends how the VM has been configured and what type of networking config is used, but if we’re talking virtualised servers that advertise services to port scanners, and / or SMB shares with their hosts, then clearly the virtualised aspect is suddenly very real. VM guests used in a NAT’ing setup is a decent way to hide information on a laptop/mobile device or anything that hooks into an untrusted network (read: “corporate private network”).
The vendor who was being interviewed finished up with “Every product sounds the same,” …”They all make you secure. And none of them deliver.” Probably if i was a vendor I might not say that.
Sorry, I just find discussions of security with “radical new infrastructure” to be something of a waste of bandwidth. We have some very fundamental, ground level problems in information security that are actually not so hard to understand or even solve, at least until it comes to self-reflection and the thought of looking for a new line of work.
All of these “VM” and “cloud” and “BYOD” discussions would suddenly disappear with the introduction of integrity in our little world because with that, the bigger picture of skills, accreditation, and therefore trust would be solved (note the lack of a CISSP/CEH dig there).
I covered the problems and solutions in detail in Security De-engineering, but you know what? The solution (chapter 11) is no big secret. It comes from the gift of intuition with which many humans are endowed. Anyway – someone had to say it, now its in black and white.
