What Role Does a Commercial Security Firm Play in Compliance Initiatives?
Posted in Other, Security on March 9th, 2011 by Robin – Be the first to commentLinkedIn is one of the most popular social media services used by professionals to network with each other. I’m a LinkedIn member and one of its features I really enjoy is the ability to participate in “group” discussions. I belong to a couple of groups, including Security Officers and AS400 Specialists.
Last week, someone posed an interesting question to the AS400 Specialists group that elicited some passionate exchanges. It started with a simple enough question regarding what mechanism should be used to log all activity on an IBM i server (AS/400), including the requirement that it could be reviewed daily, be unalterable, and that it log data and admin changes. Of course, several people (myself included) indicated that we would need to know more before we could really offer a detailed opinion. However, one person responded that a user only needed to use the operating system controls, and if any commercial vendor tried to sell him any of their wares, he was literally being ripped off and wasting his money (I paraphrased).
Now, here’s my response: although I am employed by the leading security software company, I have always been a proponent of deploying every control, including those that are “free” in the base operating system. This includes limiting the special authorities assigned to users, correctly establishing system values, securing libraries and objects, and, as discussed in this particular online exchange, using IBM i auditing functions for events, users, and objects. Why would I suggest this? Simple! I’m a firm believer that layered security is the best approach to risk reduction. This is because multiple layers of controls are inherently more secure than one single layer.
I also responded to the suggestion that (all) commercial security companies are only out to make a fast buck. I can’t speak for my competitors, but as the Director at PowerTech, I am totally focused on helping customers make good long-term decisions about their compliance strategy. This is demonstrated by the commitment my team shows performing our popular (and free!) security assessment service. Invariably, mitigation of some of the uncovered risks involves our software, but if PowerTech were simply selling solutions for the sake of it, we would have gone out of business a long time ago. You might be surprised to read that I do not think commercial solutions totally negate the need for the built-in controls. I strongly support the necessity of object-level security, but I also know for a fact that most customers don’t have this well implemented. Even when they do, access levels that are appropriate in one interface might be totally inappropriate for another. It’s also important to remember that the IBM i security model was designed long before anyone had insight into the requirements (for example, segregation of duties) of our current regulatory world.
While you may be able to write software that’s similar in function to a commercial vendor solution, why would you spend the immense amount of time and money reinventing the wheel? Most home-grown security “solutions” don’t even start to compare to the functionality provided by a company that dedicates thousands of dollars in R&D, testing, and support each year. And one certainly can’t substitute the expertise gained from providing specialized solutions for customers around the globe. Regardless of any intent to try to save money, most auditors don’t support the idea of “self-policing.”
PowerTech’s commercial solutions will add tremendous value to your compliance efforts. Enterprises that record thousands of events each day, as some of our customers do, can’t review their logs manually. At best, it would mean that critical events often get missed, and most likely it wouldn’t get done at all. The ability to feed events into a SIM console as they happen, or send them to a mobile device when a critical situation arises, is one obvious benefit of a professional solution. Monitoring database activity, as this particular member wished to do, can be done with journaling. But, it’s far more productive when a market-proven solution is making sense of the collected data, and alerting your security team in real-time when, and only when, there is a data anomaly.
The bottom line is that there is no single measurement that indicates “you are now totally secure.” It’s all about balancing and managing risk. Even with compliance, auditors have to follow the regulations and often have differing interpretations. In my humble opinion, the IBM Power Systems servers are some of the most securable servers on the planet. But it takes work, skilled effort, and money to get it perfectly tuned. It also takes a trusted partner, like PowerTech, that invests heavily in its solutions, dedicates numerous free resources to the IBM i security community, and with the integrity to acknowledge that even our software works better when it’s used in conjunction with IBM’s own controls.
Thanks to all our customers, distributors, and employees who know the value of PowerTech solutions, and for coming back to us year after year.
Cheers,
