I write this because I have had enough of arguing over the lowest common denominator when it comes to securing networks, servers and applications. Reading the articles in the various media and trade journals, one would get the distinct impression that putting forth any sort of effort is beyond a lot of peoples’ capacity.
Do you people complaining about the difficulty of achieving compliance with a security framework ever listen to yourselves? I would say the answer is “No” because if you did, you would understand where I am going.
Do you realize that you are arguing over doing the bare minimum? I would guess that would be a resounding “No” because, again, you would understand where I am going.
If none of this rings a bell, then maybe this does. When was the last time anyone told you that only doing the minimum was acceptable? If they did, then they are people I would not want to associate with because they are likely on their way out the door as you will be shortly once that breach occurs.
All security frameworks are a bare minimum. They do not guarantee security of anything. What they do is define the “best practices” or “common knowledge” of what it takes to have a reasonable chance of being secure. But it gets worse. Security frameworks require perfect execution, i.e., being compliant 24x7x365, in order to succeed. And as those of you complaining are rudely finding out, that just does not happen when people are involved.
In order to address the shortcomings of people, security frameworks are layered. You must have heard the phrase “layered approach” time and again during security discussions. The layers are there so that when people fail, their failure does not result in a total failure of an organization’s security posture. Where things go wrong is when there are multiple failures. It does not matter that things are layered when the vast majority of those layers are circumvented by multiple failures.
Oh, you do not think that is how a breach happens? Read the Verizon DBIR or PCI reports on breaches and it lists out the multiple processes that failed that led to the breach, not just a spear fishing email or the breach of a firewall. Those were the start of it all, but it was a lot of other things that ultimately led to the success of the breach.
Another rude awakening for management and security professionals alike is how easily all of that security technology they have invested in does nothing once a phishing email corrupts an insider’s account. That is because a lot of organizations’ security posture is like an M&M candy – hard on the outside with that soft chocolate center on the inside. If you go back to the Verizon reports, read the details of how many attacks came to fruition over insider accounts being corrupted. They may not necessarily be categorized as insider attacks, but an insider was compromised as part of the successful attack.
Which brings me to security awareness training and the fact that people consistently complain that it is worthless. Did you people really believe that one session, once a year is really going to change peoples’ bad habits? If you did, I have some property I would like to sell you. You must harp on this topic constantly and consistently. I know that is not what you want to hear, but people only learn by being told repeatedly to stop their bad habits. Even though a lot of people approach this subject by making it annoying and painful, it does not have to be that way. But it is the only way to have an effect and it will not happen overnight and not everyone will learn the lessons. Security awareness takes years and lots of patience, but it does eventually pay off.
The bottom line is security is a war between you and the people that want your organization’s intellectual property, card data, medical records, financial information, whatever information you are trying to protect. Wars are won or lost on the strategy used and the battle intensity of the soldiers involved. Wars and battles are not won with mediocrity which is the approach upon which you are arguing. Mediocrity in war is how people die, not how they survive.
Let me know how that mediocre approach works out. That is, if you are even around to let me know.
