Tableau Metadata Model

The first layer of abstraction is the Connection. The Connection stores information about how to access the data and what data to make available to Tableau. The connection attributes for the database, the tables, views and columns to use, and any joins or custom SQL used to access the data. To support true ad hoc analysis, Tableau does not require that all fields, tables or joins be included in the initial connection. This allows users to get started with a simple connection and change it as needed to include more fields or tables.

Google BigQuery & Tableau: Best Practices

Tableau helps people to see and understand data. Our software products put the power of data into the hands of everyday people. This allows a broad population of users to engage with their data, ask questions, solve problems, and create value. Based on technology developed at Stanford University, our product reduces the complexity, inflexibility, and expense associated with traditional business intelligence applications. Anyone who is comfortable with Excel can leverage Tableau Desktop to create rich, interactive visualizations and powerful dashboards using a drag-and-drop user interface, as well as share them securely across organizations using Tableau Server or Tableau Online.

Trust Online is at the Breaking Point

Most alarming threat to security professional in 2015 is a Cryptoapocalypse: a discovered cryptographic weakness that becomes the ultimate weapon, allowing websites, payment transactions, stock trades, and government to be spoofed or surveilled (term was coined by researches presenting their findings at Black Hat 2013).

When Trust Online Breaks, Businesses Lose Customers

This is the second part of the Ponemon Institute’s 2015 Cost of Failed Trust Report, which reveals the damaging impacts on global business from unprotected cryptographic keys and digital certificates. This new report reveals that most companies lose customers, suffer costly outages, fail audits, and experience breaches due to unprotected and poorly managed keys and certificates.

Managed File Transfer Survival Guide – Implement a Successful MFT Strategy

More than a third of all business-critical processes involve managed file transfer but many people underestimate the effort it takes to be successful with the strategy. MFT is not a simple install-and-go solution. In this final installment of our MFT Survival Guide series, we walk the phases of incremental MFT implementation to ensure a smooth transition to the world of high-end managed file transfer.

In this white paper, you will learn:

•How to build a solid business case for a Managed File Transfer project

•How to create and execute a project blueprint

•Why testing MFT processes is important and how to do it

•How to support your MFT solution and plan for future functionality

Unfettered Mobility: Driving the International Extended Enterprise

Organisations are increasingly international in both their outlook and their operations. Despite these developments, international workers continue to be impeded by their organisations' approaches to mobility.

IDC research highlights that when working internationally, employees make a distinct change in their communication preferences, becoming less available and less collaborative. This impacts both productivity and job satisfaction.

This whitepaper outlines the learnings that can be implemented in mobile policies by senior decision makers who are responsible for managing telecommunications across the globe.

Unfettered Mobility: Research Highlights

Organisations are increasingly international in both their outlook and their operations. This is being driven by developments in the global economy and the search for new partners, as well as access to travel and communications. As a result, businesses are making greater use of a global network of customers, suppliers and partners. IDC refers to this network as the International Extended Enterprise.

Unfettered Mobility: Driving the International Extended Enterprise

Over half (52%) communicate with international customers, partners and colleagues several times a day, but were less likely to travel and meet them in person. In fact, 40% travel just once or twice a year, in comparison with the 28% average across all respondents.

Eliminate Blind Spots in SSL Encrypted Traffic

Many security systems now perform high speed SSL/TLS decryption. But these systems cannot decrypt traffic if they don’t have access to keys and certificates. To eliminate blind spots in encrypted traffic, you need to secure your keys and certificates. Otherwise, your other security controls become less effective and leave the door open to cybercriminals.

Stop Unauthorized Privileged Access

SSH is a cryptographic security protocol used to connect administrators and machines. While SSH keys are often used to secure access to the most sensitive systems and data, there is usually little awareness or policy enforcement in place around their use. If you don’t know which administrator or SSH key has access to which servers, your IT environment may already be at risk.

Removing the Complexity and Guesswork from Your PKI Refresh

Venafi automates, streamlines, and validates your PKI refresh, scaling to hundreds of thousands of keys and certificates. And with automated integration across hundreds of applications, devices and CAs, you can deliver policy-enforced replacement or remediation of certificates in just minutes.

Failure to Protect Keys and Certificates Undermines Critical Security Controls

Advanced Persistent Threat (APT) operators have proven they can breach enterprises like yours by undermining your critical security controls when you fail to protect digital certificates and cryptographic keys. Not securing all of your keys and certificates enables cybercriminals to bypass controls like threat detection, data protection, firewalls, VPNs, DLP, privileged access, and authentication systems that you expect will mitigate threats.

Prevent Costly Outages Due to Expired Digital Certificates

Your organization, like so many others, is most likely increasing its use of SSL/TLS to protect sensitive data and reduce risk. To accomplish this, organizations rely on digital certificates to enable encryption and authenticate communications for customers, partners, and employees. These digital certificates are also used to secure machine-to-machine authentication and mobile applications.

Hearts Continue to Bleed: Heartbleed One Year Later

Using the recently released Venafi TrustNet certificate reputation service, the Venafi Labs team re-evaluated SSL/TLS vulnerabilities in Q1 2015 and found that most Global 2000 organizations have failed to completely remediate Heartbleed—now a full year after the vulnerability was first publicly disclosed.

This leaves these organizations vulnerable to cyberattacks, future brand damage, and intellectual property loss. In one oft-cited incident, Community Health Systems was breached by the Chinese APT 18 group, who exploited incomplete Heartbleed remediation and unprotected keys to steal data on 4.5 million patients.
