Catch More Threats

Since every cause needs “Awareness,” here are my picks for management speak to camouflage the bloody obvious:
5. Events per second
Log Management vendors are still trying to “differentiate” with this tired and meaningless metric as we pointed out in The EPS Myth.
4. Thought leadership
Mitch McCrimmon describes it best.
Now here is a term that means all things to all people.
2. Does that make sense?
The new “to be honest.” Jerry Weismann discusses it in the Harvard Business Review.
During the recent SOPA debate, so many self-described “country boys” wanted to get the “nerds” to explain the issue to them; as Jon Stewart pointed out, the word they were looking for was “expert.”

Nearly every analyst has made aggressive predictions that outsourcing to the cloud will continue to grow rapidly. It’s clear that servers and applications are migrating to the cloud as fast as possible, but according to an article in The Economist, the tradeoff is efficiency vs. sovereignty. The White House announced that the federal government will shut down 178 duplicative data centers in 2012, adding to the 195 that will be closed by the end of this year.
Businesses need motivation and capability to recognize business problems, solutions that can improve the enterprise, and ways to implement those solutions. There is clearly a role for outsourced solutions and it is one that enterprises are embracing.
For an engineer, however, the response to outsourcing can be one of frustration, and concerns about short-sighted decisions by management that focus on short term gains at the risk of long term security. But there is also an argument why in-sourcing isn’t necessarily the better business decision: a recent Gartner report noted that IT departments often center too much of their attention on technology and not enough on business needs, resulting in a “veritable Tower of Babel, where the language between the IT organization and the business has been confounded, and they no longer understand each other.”
Despite increased migration to cloud services, it does not appear that there is an immediate impact on InfoSec-related jobs. Among the 12 computer-related job classifications tracked by the Department of Labor’s Bureau of Labor Statistics (BLS), information security analysts, along with computer and information research scientists, were among those whose jobs did not report unemployment during the first two quarters of 2011.
John Reed, executive director at IT staffing firm Robert Half Technology, attributes the high growth to the increasing organizational awareness of the need for security and hands-on IT security teams to ensure appropriate security controls are in place to safeguard digital files and vital electronic infrastructure, as well as respond to computer security breaches and viruses.
Simply put: the facility of using cloud services does not replace the skills needed to analyze and interpret the data to protect the enterprise. Outsourcing to a cloud may provide immediate efficiencies, but it’s the IT security staff who deliver business value that ensure long term security.

Cloud computing has been described as a trade off between sovereignty and efficiency. Where is security (aka Risk Transfer) in this debate?
Chris Hoff notes that yesterday’s SaaS providers (Monster, Salesforce) are now styled as cloud computing providers in his post .
CIOs, under increasing cost pressure, may begin to accept the efficiency argument that cloud vendors have economies of scale in both the acquisition and operations of the data center.
But hold up…
To what extent is the risk transferred when you move data to the cloud? To a very limited extent, at most to the SLA. This is similar to the debate where one claims compliance (Hannaford, NYC and now sadly Mumbai) but attacks take place anyway, causing great damage. Would an SLA save the Manager in such cases? Unlikely.
In any case, the generic cloud vendor does not understand your assets or your business. At most, they can understand threats, in general terms. They will no doubt commit to the SLA but these usually refer to availability not security.
Thus far, general purpose, low cost utility or “cloud” infrastructure (such as Azure or EC2), or SaaS vendors (salesforce.com) do not have very sophisticated security features built in.
So as you ponder the Sovereignty v/s Efficiency tradeoff, spare a thought for security.

The Economist opines that the world is flirting with recession and IT may suffer; which in turn will hasten the move to “cloud computing”, which in a pithy distillation is described as “a trade-off between sovereignty and efficiency”.
Computing as a borderless utility? Whereas most privacy laws assume data resides in one place…the cloud makes data seem present everywhere and nowhere.
In a recent post Steve differentiated between security OF the cloud and security IN the cloud. This led us to an analysis of cloud computing as it is currently offered by Amazon AWS, Google Apps and Zoho.
From a risk perspective, security of content IN the cloud is essentially considered your problem by Amazon whereas Google and Zoho say “trust in me, just in me”. When pressed, Google says “we do not recommend Google Apps for content subject to compliance regulations” but is apparently working to assuage concerns about access control.
However moving your data to the cloud does not absolve you from responsibility on who accessed it for what purpose — the main concern of auditors everywhere.
At the present time, neither Google nor Zoho make any audit trail available to subscribers while at Amazon it’s your problem. We think widespread adoption by the business community (and what of the federal government?) will require significant transparency to provide visibility. This is also true for popular hosted applications like Intuit Quickbooks and Salesforce.
As Alex notes “…in order to gain that visibility, our insight into Cloud Risk Management must include significant provisions for understanding a joint ability to Prevent/Detect/Respond as well as provisions for managing the risk that one of the participants won’t provide that visibility or ability via SLA’s and penalties.”
Clear as mud.

In a recent post I talked a little about the security and compliance issues facing companies that adopt cloud-based SaaS for any mission-critical function. I referred to this as security OF the cloud to differentiate it from a cloud-based security offering or security IN the cloud. This is going to pose a major change in the security industry if it takes off.
Take a typical small business “SmallCo” as an example – They depend on a combination of Quickbooks and an accounting firm for their financial processes. For all practical purposes SmallCo outsources the entire accounting function. They use a hosting company to host Quickbooks for a monthly fee, and their external CPA, internal management and accounts staff access the application for data processing. Very easy to manage, no upfront investment, no servers to maintain, all the usual reasons why a SaaS model is so appealing.
One can easily argue the crown jewels of SmallCo’s entire business are resident in that hosted solution. SmallCo began to question whether this critical data was secure from being hacked or stolen. Would SmallCo be compliant if they were obligated to follow a compliance standard? Is it the role of the hosting provider to ensure security and compliance? To all of those questions there was and is no clear cut answer. SmallCo is provided access to the application and can have access to any audit capability that is supported in the Quickbook product (which is not a great deal), and there is no ability to collect that audit and usage data other than to manually run a report. At the time SmallCo began it did not seem to be important but as SmallCo grew so did their exposure.
Salesforce, another poster child for SaaS, is much the same. I read a while back they were going to put the ability to monitor changes in some of their database fields in their Winter 2008 release. But there appears to be nothing for user level auditing or even admin auditing (of your staff much less theirs). A trusted user can steal an entire customer list and not even have to be in the office to do it. The best DLP technology will not help you as it can be accessed and exported through any web browser on any machine. Having used Salesforce in previous companies I can personally attest, however, that it is a fine CRM system, cost-effective, powerful and well-designed. But you have to maintain a completely separate access control list, and you have no real ability to monitor what is accessed by whom for audit purposes. For a prospect with privacy concerns is it really a viable, secure solution?
Cloud based computing changes the entire paradigm of security. Perimeter defense is the first step of a defense in depth to protect service availability and corporate data, but what happens when there is no data resident to be defended? In fact, when there are a number of services in the cloud, is event management going to be viable? Will the rules be the same when you are correlating events from different services on the cloud?
So here is the challenge I believe — as more and more mission critical processes are moved to the cloud, SaaS suppliers are going to have to provide log data in a real-time, straight forward manner, probably for their admins as well as their customers’ personnel. In fact since there is only a browser and login and no firewall, network or operating system level security to breach, auditing would have to be very, very robust. With all these cloud services is it feasible that an auditor will accept 50 reports from 50 providers and pass the company under audit? Maybe, but someone – either the end-user or a MSSP has to be responsible for monitoring for security and compliance, and unless the application and data is under the control of end-users, they will be unable to do so
So If I were an application provider like Salesforce I would be thinking really hard about being a good citizen in a cloud based world. Like providing real-time audit records for at least user log-on and log-off, log-on failures and a complete audit record of all data extracts as a first step, as well as a method to push the events out in real-time. I would likely do that before I worried too much about auditing fields in the database.

There is a lot of discussion around Security MSSPs, SaaS (Security as a Service) and Cloud Computing these days. I always felt I had a pretty good handle on MSSPs and SaaS. The way I look at it, you tend to outsource the entire task to Security MSSPs. If you outsource your firewall security, for instance, you generally have no one on staff that worries about firewall logs and you count on your MSSP partner to keep you secure – at least with regards to the firewall. The MSSP collects, stores and reviews the logs. With SaaS, using the same firewall example above, you outsource the delivery of the capability — the mechanics of the collection and storage tasks and the software and hardware that enable it, but you still have IT personnel on staff that are responsible for the firewall security. These guys review the logs, run the reports etc. This general definition is the same for any security task, whether it is email security, firewall or SIEM.
OK, so far, so good. This is all pretty simple.
Then you add Cloud Computing and everything gets a little, well, cloudy. People start to interchange concepts freely, and in fact when you talk to somebody about cloud computing and what it means to them, it is often completely different than what you thought cloud computing to be. I always try to ask – Do you mean security IN the cloud, i.e. using an external provider to manage some part of the collection, storage and analysis of your security data (If so go to SaaS or MSSP)? Or do you mean security OF the cloud — the collection/management of security information from corporate applications that are delivered via SaaS (Software as a Service, think Salesforce)?
The latter case has really nothing to do with either Security SaaS or MSSP since you could be collecting the data from the applications such as Salesforce into a security solution you own and host. The problem is an entirely different one. Think about how to collect and correlate data from applications you have no control over, or, how these outsourced applications affect your compliance requirements. Most often compliance regulations require you to review access to certain types of critical data. How do you do that when the assets are not under your control? Do you simply trust that the service provider is doing it right? And what will your auditor do when they show up to do an audit? How do you guarantee chain of custody of the log data when you have no control over how, when, and where it was created? Quickly a whole lot of questions suddenly pop up that there appear to be no easy answers.
So here are a few observations:
The combination of the above is very likely going to become a bigger and bigger issue, and if not addressed will prevent the adoption of cloud computing.
