The battle to encrypt data or not...


Putting things into perspective :) Encryption...

Back it up a bit! Purpose of encryption – (a) access controls and (b) confidentiality

Let's understand the battle surrounding whether to encrypt data or not. Let's understand why we need encryption in the first place. Encryption was originally used to make absolutely sure data would remain confidential to people that shouldn't access the information. If you can't read the data because you don't have the key to the data, then we presume you don't need access.

Encryption, therefore, protects data whenever we (a) lose control over who can read the raw data or (b) where the raw data is located.

Control landscape includes encryption (and now we understand why)

Understanding this, we can see why the most common regulations and standards require encrypting sensitive data. This can be healthcare information, privacy information, financial data, Defense data, etc. This requirement gets written into law and legally binding contracts. Organizations don't have a choice whether they are supposed to encrypt certain types of information or not. 

Understand why people don't use encryption (system cost, software cost, user cost/experience)

There are several reasons why people don't want to do it. The software costs money. There may be a perceived performance impact. There may be a perceived impact on user experience. Maybe the thought of encryption sounds intimidating or complex.

Bruce Schneier wrote attack the system as well as the algorithm (and he's right)

Many years ago, Bruce Schneier wrote a book titled Applied Cryptography. In this book, he explains the purpose of cryptography and how to correctly apply it to solve business problems. Afterward, he wrote another book titled Secrets and Lies where he explains the effective use of encryption is much more than the math that goes into protecting data. Think about that. It's more than the algorithm. It's all of the supporting pieces of the process. It's the system itself in which the encryption is used, that represents the available angles of attack. Consider a door with a world-class lock. It's in a house with a giant window in the front. Do I attack this the lock, or smash the window? This is what happened in the Capital One breach.

Encryption is hard. Why? Encryption is hard because it's more than just choosing a strong algorithm to protect the data. I must ensure that the use of the algorithm doesn't inadvertently open doors around my encryption. I must constantly review and validate the configuration of the endpoints, application configuration, access controls, auditing processes, and so many other items could prevent attacks similar to what happened with Capital One.

Caveonix integration with HyTrust… (validate the system and use of the algorithm)

This is why our company Caveonix jumped at the opportunity to integrate with HyTrust. You must validate the use of encryption because it's required, and you must validate the system itself to ensure there is no way around the encryption. This is why Caveonix chose to integrate with HyTrust as part of IBM's approach to securing Financial Services. Together, Caveonix and HyTrust can do both.


CapitalOne breach with Bloomberg Technology’s Emily Chang

This was an incredible opportunity to appear on Bloomberg TV and share my thoughts on the CapitalOne breach. Doing what they are doing is harder than it may sound. This is why I love working at Caveonix and researching ways to address these challenges.

From our PR desk: "Last night our Vice President of Product Management, Chris Davis talked about the #CapitalOne breach, #cloudsecurity, and systems #misconfiguration with Bloomberg Technology’s Emily Chang. Check out the interview here at the 21-minute mark:  https://www.bloomberg.com/news/videos/2019-08-16/-bloomberg-technology-full-show-8-15-2019-video"

You simply cannot manage what you cannot see.

Another round of questions for an article contribution... 

Sometimes, risk and compliance can be at loggerheads. You need to mitigate a risk, but can you do it and still be compliant?

Can you? Absolutely. Risk and compliance are very rarely in conflict. (No *good* examples come to mind...) The entire GRC model created by Michael Rasmussen when he was an analyst at Forrester presumes that compliance is addressed first, and any additional safeguards necessary to protect data assets are then reviewed and applied according to the probability and impact of adverse events affecting the data assets. This is the definition of risk management. Therefore, compliance is addressed first, and any additional measures necessary to protect data – risk management – are applied.

Where are the biggest stresses and strains in the governance, risk and compliance balancing act?

By far – Governance. It's one thing to get your systems compliant, appropriately risk managed, and ready for operations on day one. However, managing day to operations and beyond is extremely difficult. Mature organizations and excellent leadership implement compliance and security hygiene processes, often called entity level controls, and communicate their importance throughout the organization. When this is done well, projects default to security-first and compliance-first postures. The result? Security and compliance are implemented throughout the development and deployment of new systems, becoming part of the solution instead of part of the problem when it's time to go into production.

Do you have any advice on “getting it right”?

You simply cannot manage what you cannot see. Visibility into the inner workings of the workloads and infrastructure the provides insight into your compliance configuration and potential vulnerability exposures is a necessary input for governance processes to manage security and compliance.

How important is risk assessment?

Out of more than 300 controls in PCI DSS 3.2.1, here is the list of the top 10.

Dangerous (animals, munitions, substances… or data)
  • Know what you have
  • Know where it goes
  • Keep as little as possible
  • Destroy it when you can
  • Make sure you got it right (Risk Management)

Notes on Data Governance -- How do you manage data?

1) What are the major EXTERNAL laws/regulations shaping data governance requirements this year?

Consumer privacy and data sovereignty are in the forefront of the news and the focus of regulatory compliance this year. GDPR, California Consumer Privacy Act, HIPAA, and others are driving internal business decisions related to technology use. Critically, the center point of many of these includes understanding the risk impact across the organization and including risk impact in your business decisions.  

2) What are the major INTERNAL factors or requirements that require more vigilant or comprehensive data governance?

Internal factors driving – demanding – more vigilant and comprehensive data governance include respecting consumer and government data rights. Consumers are increasingly savvy and protective of their privacy in the backwash of Facebook and Google’s data analytics practices, and governments continue to require data sovereignty. Organizations with multinational locations must deal with these complexity factors when managing data across use cases and geographic locations. In each case, however, data should be aggregated to the extent possible, protected and monitored per applicable and changing requirements. This is a real challenge that requires proactive management.   

3) Are organizations keeping up with these requirements?  

Organizations struggle with the requirements. The diverse topology of new cloud-inclusive hybrid architectures and the velocity of new requirements have created a blind spot to understand what needs to be done. There is a lot of activity but it is not always the right activity. Keeping up is a challenge.

4) What tools or technologies are assisting with efforts to achieve more effective data governance? (Note to vendors: okay to discuss product categories, such as AI/machine learning, but we cannot mention specific product names, sorry.)

Three specific elements – visibility, alignment, control – work together to provide effective data governance. There are tools and technologies which provide visibility across portions of the enterprise, perform analytics, and offer some control. The ideal solution digs deep to detect every asset across the enterprise, performs predictive analytics, and provides necessary and often-repeated actions such as reporting, mitigation, and forensic detail. The differences are in scope, scale, manageability, and producing truly meaningful information. If you can’t produce meaningful and actionable information from a tool, that it’s time to rethink the value of that tool.

5) What types of changes are necessary to organizations, and the way people are managed, to achieve more effective data governance?

Organizations looking to understand the people part of the data governance problem over time have to have a firm grip on the content of their data and the body of relevant requirements from regulations, standards, best practices, and organizational policies that apply. Content and Requirements. These can change often. The most effective way to manage people is to communicate the importance of data content and regulatory requirements, including how to provide effective data governance over compliance and data risk.

Sales Engineering -- Quick Question Hit List

Need a direct list of short questions to identify where you fit in a potential solution? Here you go:

  1. How painful is this? 
  2. Who's involved? 
  3. When do you want to solve this? 
  4. What are you doing now? 
  5. How can I solve this?

A short list of considerations: 

  • Your customers buy from people they like. There's a complex vibe going on mixing personality, likability, respect, and trust. 
  • Keep it simple. The more convoluted the answers, the more I start looking for BS.
  • Avoid word games and cliches. Use industry terms in grammatically correct context. But let it go if someone speaks with artistic license as long as the point is made. 
  • Match tone and pace. If I'm tired - don't come at me like a rabid pit bull. Just slow down and chill. If I'm upbeat, then don't bring me down. Match me. Then take me for a ride. Watch experienced Grandmothers. They'll do this with small children, and it works like a charm for adults too.

Technology changes. Politics have not.

Excerpt from something I wrote many years ago. Thinking about this now because it's in a chapter I'm updating from nine years ago.

An Introduction to Legislation Related to Internal Controls
The global nature of business and technology has [...created standards bodies]. Participation in these standards bodies has been voluntary, with a common goal of promoting global trading for all countries at all levels. Individual countries have gone further to establish governmental controls on the business activities of corporations operating within their boundaries.

The reality is much more complex than this, as national interests, industry concerns, and corporate jockeying create political drivers that motivate the creation and adoption of legislation at all levels. Politics can have a negative connotation, but in this sense, we simply mean the clear understanding that regulations generally benefit or protect a representative group of people. Nations, industries, and companies have concerns about the confidentiality, integrity, and availability of information. Agreed upon standards and legislation is one method of ensuring concerns are met.

The unfortunate reality is that not all sets of requirements are written equally. Sometimes it's the interests involved. Sometimes it's the people. Self-interests, self-promotion, arrogance, inexperience, lack of help, poor communications. These get in the way of results.
