A U.S. Army intelligence specialist? Walking out with confidential documents on a CD? Impossible.

When I first heard about the exposure of hundreds of diplomatic memos, I was anticipating a sophisticated cloak and dagger tale. But Pfc. Manning walked out the door with a bogus Lady Gaga CD-RW filled with government secrets. While my initial reaction was that this never should have happened, I can see where the dual priorities of a worker-friendly environment and the mission-critical imperative to share information quickly could have led to this situation. The good news is that there is a straightforward regimen to help stop these kinds of risks.

1) Install Device Control

Device control, as its name suggests, controls what devices can be used on a given computer. So if you want to disallow CD burning by a government security analyst with access to secret documents, you can do so...

In the past, it was fairly easy to keep corporate data protected by keeping it within an established perimeter—protected by established access controls and passwords.  That model has been blown apart as iPhone, iPad and other smartphones and tablets have taken over. Add to that the accessibility and usability of file sharing services like Dropbox and you can see why this transformation has information security managers concerned. These are not trends that organizations can deal with by saying “no.”  They urgently need solutions to help secure confidential data and limit access.

Today, we’re pleased to announce that Symantec’s new encryption solutions, powered by PGP Technology, are now shipping. With this Symantec Encryption release, Symantec leverages our encryption portfolio to ensure cloud data remains safe while keeping it accessible, and to protect confidential email for mobile.

Here’s a look at what’s new....

Folks, the holidays are almost once again upon us.  I sit here today trying to clear off my deliverables before I go on vacation.  But you know what? The year simply would not be complete without having to respond to yet another claim of a 3rd party tool being able to decrypt/access a system encrypted by PGP Whole Disk Encryption.

So Here We Go Again…
This morning, I was made aware of a claim made by ElcomSoft that their product could decrypt PGP containers (as well as other Full Disk Encryption competitors).  After reading through their blog and discussing my thoughts with the Symantec Encryption Engineering team, we have come to the conclusion that this claim is false!  There’s truly nothing to see here. 

The Weakness is NOT the Crypto Containers
I would agree that the...

There's a growing buzz in the industry about "who" should be responsible for encryption in the cloud from a user perspective.  As usual, the technology to do this is not the hard part – crypto is crypto is crypto, etc.  It's really more of a privacy and legal issue; privacy from the perspective of preventing others from seeing your stuff in the cloud and legal from the perspective of who has control over that data that is secured in the cloud.  
 
I think we all get the idea of privacy of our data in the cloud.  For example, if you put your personal financial data in the cloud to either be stored and/or used by an application, you want to make sure the data is secure.  If it's just storage, then you can personally encrypt the data before you store it in the cloud using encryption solutions like PGP.  If you're lucky enough to have a cloud provider that encrypts it for you, but gives you complete...

Today it is common for projects to be completed not by an individual, but a team (including to create this blog post).  To allow for improved productivity and collaboration, people use cloud-based storage to share files quickly and easily.  A counterpoint to the desire to share is the need to protect confidential information from being accessed inappropriately and leaking sensitive data.

The need for a secure collaboration solution drove the Symantec Encryption team to develop an enhancement for our Symantec™ File Share Encryption, Powered by PGP Technology software.  The enhancement offers:

  • automatic encryption of files on managed Windows machines that are stored on Dropbox
  • seamless access to encrypted files on Windows machines and iOS devices
  • centralized management for Dropbox Cloud Encryption Policies via Symantec™ Encryption Management Server (SEMS)

Encrypting files before they are uploaded to the...

Stuck at the DMV?  Reply to some email.  Waiting to get your car washed?  Review an upcoming press release.  Stuck in traffic?  Edit the monthly sales forecast - send it back.  At the airport?  You get the point. 

(Dear California Highway Patrol Officer, I would never text and drive, I swear… honestly, please stop staring at me, okay, okay, I’m putting it down.)

Most people don’t even think twice about doing work wherever they are thanks to the vast array of mobile devices on the market.  What’s scary is how comfortable we are throwing sensitive data around and storing it on unsecure devices without even a thought of whether or not it’s safe to do so.  So… how does an organization enable their workforce to continue the working experience they’ve grown used to but have the peace of mind that they’re not going to end up on some news wire explaining how they lost...

On Trust

 

I first came across Ken Thompson's Turing Award acceptance speech, Reflections on Trusting Trust, when I was in graduate school.  I found it very thought-provoking, and for a moment wondered if there weren't such vulnerabilities hidden away in the systems I used.  At some point, you decide to either give your trust, or withhold it.

 

I worked for 5 years at Xcert International, a startup that developed and sold Certificate Authority and related PKI products.  A PKI is rooted at a single point (the Root CA).  Root CAs are often referred to as "Trusted CAs" but I never thought of them that way, even though certificate vendors like to use the word "Trust" when describing their services.  A certificate provides identity information, certified by a signer -- "This person (the certificate subject) is associated with this public key, and the following associated...

I'm David Finkelstein, and welcome to my Encryption Blog.

 

Here I'll share with you some of my thoughts and observations on security in general, and encryption in particular.  I might discuss in detail the security aspects of Symantec's encryption products, but I'll leave the product announcements and  business related messages to others.  My interest is in cryptography and security, as practiced here at Symantec and elsewhere.

 

I've worked for security related companies for over 15 years.  Here at Symantec, I'm the Director of Engineering responsible for the Encryption group's Core Cryptographic team.  We produce the PGP Software Development Kit, a FIPS validated cryptographic toolkit used throughout Symantec, as well as PGP Command Line, the absolute best OpenPGP compliant application available (though I freely admit my opinion is biased).

 

So welcome to...

If you recently purchased a MacBook Air (Model 5,2) or a MacBook Pro (Model 10,1), do NOT encrypt your laptop with the current release of PGP Whole Disk Encryption for Macs (10.2.1 Build 4461).

These are the latest Macs just released by Apple based on the Ivy Bridge Processors from Intel.

Based on our QA testing thus far, we are observing these Macs not booting properly after authenticating the PGP WDE Bootguard screen. Our engineers are aware of the problem and are busily working on a solution to this.

Please check back to this blog for the latest updates.

UPDATE:
7/17/2012 @ 1:57 PM PST - Hot off the presses from engineering.  A hotfix to address this issue should be available by the end of July or beginning of August.  I will update this posting with any follow-up information that I have.  Thanks for your patience...

The newest version of OS X, 10.8 - Mountain Lion is scheduled to be released sometime in July of 2012 by Apple.

Based on past experiences, we do NOT recommend users currently encrypted with PGP Whole Disk Encryption or SEE Full Disk Encryption for Macs upgrade to OS X 10.8 when made available by Apple.

Symantec is actively testing PGP WDE and SEE FDE against the 10.8 developer builds from Apple. We will continue testing against all developer builds from Apple and also against the official release from Apple.

As a reminder, you should not upgrade to 10.8 if you wish to continue to use WDE.  If you must upgraded to 10.8, then please decrypt your disk prior to installing 10.8.  Once on 10.8, please do not re-encrypt at this point in time.  

Please check back to this blog for updates as they become available...
