Re: Encryption
I hope so. We plan to run a survey on encryption use in Q1, and trend it back to one we did in 2011. I will be very interested to see movement. What are some of the companies that you find interesting?

Re: Encryption
There are distributed key management solutions coming along so you are not dependent on a root key.  True security woudl require you not to be exposed to a single point of failure with a root key.

Re: Encryption
Lorna - you are right! Encryption currently has very low usage - key management is an issue so is latency and performance.  However there are solutions emerging that address all elements of this.  The security discussion is now in the boardroom and the downside of data leakage is so high that I believe top down mandates are coming to push encryption to the data level.  We will see.

Re: Encryption
@Lorna, very good question - in my opinion the data encryption is always a kind of paradox. Without encryption, the data will not be secure and you are exposed to security breach. If you try to encrypt everything, then what about if you lose your encryption key? The modern key management mechanism helped to give some relief on this issue. But the problem is not completly solved - there is still the trouble to renew the certificate in case it's lost. Another more severe question is that, how can we fully trust the root CA itself?

The Perimeter is Less Important
I think your general approach is right.  We can't ignore the perimeter, but defending it is no longer the be all and end all of security.  What's required is constant, real-time (and therefore automated) monitoring of data within the perimeter.

Security evolution
I agree that security needs to focus on the data, rather than the devices, systems and locations where we keep it. Those other elements are changing so quickly we can't possibly keep up. Another transition for security pros is to learn how to respond and recover after a breach or attack, and to put as much effort into that as into prevention. If your company is singled out and targeted, the best you may be able to do is cut your losses.

Encryption
Your comment "one way to attain broad data encryption is to institute corporate-wide policies that say data can never be in the clear when it is in rest or in motion and to standardize on a commercial key management system." makes a huge amount of sense. However, actual use of encryption is in the single-digits in many surveys. Best case, databases at rest are encrypted. End user devices? Forget it. The usual excuse is key management -- that  these systems are still too complex and expensive.

What's your advice to IT pros who want to expand encryption but are running scared of losing keys?

Everything You Need to Know About DNS Attacks
It's important to understand DNS, potential attacks against it, and the tools and techniques required to defend DNS infrastructure. This report answers all the questions you were afraid to ask. Domain Name Service (DNS) is a critical part of any organization's digital infrastructure, but it's also one of the least understood. DNS is designed to be invisible to business professionals, IT stakeholders, and many security professionals, but DNS's threat surface is large and widely targeted. Attackers are causing a great deal of damage with an array of attacks such as denial of service, DNS cache poisoning, DNS hijackin, DNS tunneling, and DNS dangling. They are using DNS infrastructure to take control of inbound and outbound communications and preventing users from accessing the applications they are looking for. To stop attacks on DNS, security teams need to shore up the organization's security hygiene around DNS infrastructure, implement controls such as DNSSEC, and monitor DNS traffic
