Data Breaches: Assess and Mitigate IT Risks (Part 2)

Can higher quality data lead to smarter security?

Data Breaches: Assess and Mitigate IT Risks

 

Exactis, a US-based marketing firm you didn’t know existed, discovered earlier this year that it was storing its database of 340 million customer records on a publicly accessible server. The security firm which located the risk told WIRED it was one of the most far-reaching databases of information it had ever seen—the entirety of which was easily vulnerable to attack.

Exactis’ failure presents obvious parallels to Equifax Inc.’s 2017 breach of 143 million US customers’ Social Security Numbers and much else. Disasters like it are why Senator Elizabeth Warren is championing for an Office of Cybersecurity at the US Federal Trade Commission to enforce higher data protection standards for handling consumer records.

The core principles of Senator Warren’s proposed Data Breach Prevention and Compensation Act of 2018 (DBPCA) became a reality in the European Union as of last May. For EU members it’s called the General Data Protection Regulation (GDPR)—and the LeanIX blog has reported on it from conception to reality plus hosted compliance seminars with those like Andreas Bosch from McKesson. But seeing that many EU companies grapple with its terms, are American enterprises likely to also struggle if/when their turn to submit?

And more specifically, must Enterprise Architects re-think operations to prepare for whatever wave of intensified scrutiny is coming their way?

Let’s check some of the DBPCA’s key points to see how LeanIX’s IT management tool could protect American firms once the Cybersecurity authorities come knocking...

 

Sec. 3. (b)(1)(B)(i)(I)(aa) asset management, including—

(AA) an inventory of authorized and unauthorized devices;

(BB) an inventory of authorized and unauthorized software, including application whitelisting

If you are a business receiving information from the public, then the proposed DBPCA requires you to actually have what it takes to store that information safely. To do so, the Office of Cybersecurity wants details of your system and network security measures—in particular: “an inventory of authorized and unauthorized devices; (BB) an inventory of authorized and unauthorized software, including application whitelisting; and (CC) secure configurations for hardware and software”.

 

IT security management with enterprise architecture

 

What this means is that you better have full access to high quality data across your IT portfolio to evaluate compliance readiness. And if you don’t, now is a perfect time to finally digitalize your database to an application like LeanIX to make such a flexible overview possible.

Transferring (or, as we say, “modernizing”) bulk amounts of system data to evaluate the security of your IT landscape can be managed in LeanIX from a variety of sources. If starting entirely from scratch, data in Excel sheets can be fed automatically into new or existing “Fact Sheets”—the single-page banks of information which make up the LeanIX analytics network.

Fact Sheets communicate with one another to detect strengths and weaknesses in IT networks, and the more defined they become, the more nuanced your insights into how well your company can defend against data breaches. That being said, accuracy of information is paramount to helping Fact Sheets uncover the not-so-cool vulnerabilities lying in wait to bring irreparable harm to a company.

So, to ensure the right data is fuelling your security reports, LeanIX administrators have certain tools at their disposal to pull only the best data to gauge security preparedness…

 

Fact Sheet Completeness

Yes, as the title quite literally suggests, the “Completeness” of a Fact Sheet is one way to safeguard against junk application data. Completeness is calculable in LeanIX based on which Fact Sheet fields you choose to make optional or mandatory, and the percentage is determined by the “weight” (the importance) and “status” (the applicability) given to each element. Each application in your landscape is meant to be advantageous for its own reason, so if you believe one presents greater value for (*hint* *hint*) the purposes of customer data protection, you can load it accordingly.

Take a look at how a Fact Sheet can be weighted in the below image:

 

FactSheetSettings-Weight

Quality Seal

One reason LeanIX is designed to be a collaborative tool is to maximize information-gathering efforts. Increased participation nevertheless requires everyone to be following clear quality assurance marching orders. The LeanIX “Quality Seal” is a mechanism to protect Fact Sheets from slipping into irrelevance by automating reminders to those responsible for its maintenance. Quality Seals appear on the top right of a Fact Sheet and will “break” if past their review date. A broken seal will trigger a surly mail to all responsible parties (thereby allowing you to appropriately level blame for jeopardizing your company’s integrity).

 

Surveys

Everyone loves beautifully qualified, up-to-date application data. So give the gift of love today by delivering configurable surveys, en masse but without individual mailings, to let your teammates (wherever they may be) answer questions on how to revise Fact Sheets with current information. More will be discussed on surveys in the proceeding blog post, but consider the particular benefits of surveys in relation to IT security in the image below (“Assessment of application security according to IT-Grundschutz”):

 

 Survey-Security

Above are six basic but critical questions regarding applications which are almost impossible for an IT manager to ask when lost in layers of company communications channels. In theory, such an assessment of application security can mobilize participation from an entire organization. Teamwork!

 

(cc) application management, including—

(AA) continuous vulnerability assessment and remediation;

 

After foraging for precious data in the badlands of your pre-LeanIX optimized enterprise, you are now ready to open your (comically undersized) bindle to check the goods. Proposed Sec. 3. (b)(1)(B)(i)(I)(cc) demands vigilant “application management”, and quite specifically, it wants (AA) continuous vulnerability assessment and remediation”.

As mentioned in Part 1 of this blog series, an agile approach to application management is a way to pro-actively prune IT landscapes of technologies with the potential to destabilize organizations. Knowing the relationships between your operation’s applications, how each depend upon the other and what resources are needed to support their ongoing performance, is a sure-fire way to keep the gates to your confidential data shut.

To quote my EA forebears: “it is crucial to identify and understand which underlying technologies exist, their lifecycles, and any software dependencies”.

Consider how the following reporting tools in LeanIX enable the precise vulnerability assessment and remediation needed to safeguard your company's data...

 

Application Landscape

One of a number of report types offered by LeanIX is the “Application Landscape”, a configurable view on the state and interlinking relationships of applications across an operation.

Drawing from information contained inside Fact Sheets, users can create visual tables of information from an assortment of filters, many of which designed specifically for security assessment. Take the below image, for example:

 

 
ApplicationLandscape-QualitySealBroken-CustomerData

Image 4: An Application Landscape report filtering the “Lifecycles” of applications based on “Data Quality: Quality Seal Broken” with “Data Objects: Customer Data”.

 

Here we see applications sorted, at the highest level, by business service plus the five stages of operating “Lifecycle” (from “Plan” to “End of life”). The report is filtered deeper to include results with a broken “Quality Seal” and if the application is connected to the usage of “Customer Data”. As you can see, there are several applications in the red. This is an EA’s cue to investigate further what available security patch or software upgrade is needed to stop bleeding and prevent system infection.

Backdoors to customer data can surface in many locations, not just within applications dedicated to its storage. It’s therefore important to use all available Application Landscape reporting views and filters to find improvement.

 

Application Matrix

The Application Matrix reporting tool, as seen in the image below, can separate applications by geography and link distant data objects to determine shared business functions. In the snapshot below, vulnerabilities are being viewed by “Business Criticality” and filtered according to “Data Quality: Quality Seal broken” > “Data Objects: Customer Data”.

So, it appears that there are numerous applications shared by many services in the organization with broken quality seals (and thus high-potential security risks). Let’s look deeper at one of these applications to see what should be done...

 

 
FactSheet-

There are several things to consider in the above Fact Sheet for “Bonus Card Americas”. Used by business units in Brazil and the United States, Bonus Card Americas’ agreement is set to end halfway through 2019 without any documented plan for continuation.

As it is an application marked as supporting customer data and the integration of “Customer Loyalty Information”, will its phase-out strand confidential information? As well, is there a reason the operation chose to prolong support for other regional versions of Bonus Card Americas (e.g., “Bonus Card Europe”)?

Is this an oversight the Cybersecurity Office will want to know more about?

To remedy this problem, it’s suggested you look at who is responsible for updating the information of this Fact Sheet (spoiler alert: it’s been neglected).

Three users: two “Responsibles”; one “Observer”. None of whom have visited the page since 2015 to update its data. This is why the Completeness for this Fact Sheet is at “45%”.

Quick-win: Request an update via a survey, align answers with Responsibles from other regions.

 

Closing thoughts

The public is paying attention, more than ever, to the security capabilities of those they must trust (in many cases, without any alternative option…) with their information. Unassailable data protection is no longer an added value—it is the expectation.

However, while it is problematic to predict the final parameters of proposed government policies, an IT infrastructure integrated by agile Enterprise Architecture can grant you the visibility and flexibility to help your business react faster to regulatory standards.

Upgrading to a digitalized tool is the first step to properly receiving and storing the high quality data needed to base compliance insights. Follow up this knowledge with comprehensive reporting mechanisms to discover how to make this information work for you.

 

Perhaps you’d like to discuss data protection in-person at our EA Connect Days organized by LeanIX on November 22 and 23? It's two days' worth of talks and workshops on everything related to Enterprise Architecture. There will be plenty of chances to network, and it's free to join right here.
