Top insights and best practices from the new Microsoft Data Security Index report

A whopping 74 percent of organizations recently surveyed experienced at least one data security incident with their business data exposed in the previous year. That’s just one of our interesting insights from Microsoft’s new Data Security Index: Trends, insights, and strategies to secure data report, released today.  

Data security is a cornerstone of effective cybersecurity programs. Notably, of the security decision-makers we spoke to, the vast majority (89 percent) consider their data security posture critical to their overall success in protecting their data. Safeguarding sensitive information, spanning from employee and customer data to intellectual property, financial projections, and operational records, against an array of cyberthreats, data breaches, and insider risks, is a top priority for these organizations.

Every chief information security officer (CISO) I’ve spoken with has shared a daunting data security experience and expressed a desire to explore the best practices and technological innovations that can help them overcome these challenges. At Microsoft, we’re keen to help organizations navigate the complexity of data security and implement effective comprehensive strategies for strengthening their data security posture.

To facilitate this dialogue and learn more from our customers and peers, we partnered with the independent research agency Hypothesis Group to conduct a multinational survey involving more than 800 data security professionals. Our collaborative effort has resulted in the publication of the Data Security Index report, designed to offer valuable insights into current data security practices and trends. Moreover, it aims to identify practical opportunities for organizations to enhance their data security efforts.

In this blog post, I’ll dive into some of the key findings from the report, including:

Data Security Index

Microsoft commissioned a multinational survey of more than 800 security professionals to identify current data security trends and best practices.

Data security incidents remain frequent

Data security incidents continue to occur frequently with an average of 59 incidents occurring in the past 12 months, 20 percent considered severe, resulting in potential annual costs of up to USD15 million.

While decision-makers are attempting to make the best use of the tools they currently employ, it’s not enough to mitigate the continued frequency of data security incidents.

Vulnerabilities manifest in various dimensions due to a diverse set of factors

One of the primary reasons data security incidents occur more commonly than desired is the expanding diversity and complexity of risks associated with data. These encompass a variety of factors such as the causes of the incidents, the need to safeguard different types of data and the challenges presented by data processed and stored across various locations and workloads.

Among all causes of data security incidents, decision-makers expressed their least preparedness in preventing malware, ransomware attacks, and malicious insider incidents. When considering the types of sensitive data at risk of exposure—business data, such as intellectual property, is at a higher risk compared to operational and personal data. Additionally, as cloud and AI become imperative for organizations to drive digital transformation—security teams need to deal with the complexities of protecting data across a variety of locations and application types.

A fragmented solution landscape can weaken data security posture

How can organizations effectively navigate the multifaceted landscape of data security risks? Often, various use cases within different aspects of data security efforts may necessitate the adoption of distinct solutions. In the physical realm, adding more locks to a door typically enhances security. However, in the context of cybersecurity tools designed to safeguard data, the situation is quite the opposite. Organizations employing more than 16 tools to secure data face a staggering 2.8 times more data security incidents compared to those who use fewer tools. Moreover, the severity of these incidents tends to be higher as well.

For each tool an organization adopts, it necessitates dedicated staff and processes, primarily because each vendor provides its distinct portal with varying technological foundations. Take data classification as an example; when organizations use siloed solutions, each solution might have its own classification service, resulting in data being classified multiple times based on specific use cases.

The proliferation of tools also leads to an increase in the number of alerts, and at times, these alerts may be duplicated, creating more noise in the system. According to the report, organizations using a greater number of tools receive more than double the volume of alerts compared to those with fewer tools. However, they can only review a smaller percentage of these alerts.

Now, imagine a scenario where an incident occurs—each administrator of each tool must initiate their own investigations within their respective areas of expertise. Subsequently, they convene to deduplicate alerts, correlate insights, and determine the nature of the incident. Unfortunately, insights may occasionally get lost in translation because they originate from disparate systems, ultimately resulting in longer time to conclude an investigation.

Decision-makers seem to have the correct intuition about this, with 80 percent agreeing that a comprehensive data security platform with integrated solutions is superior to multiple and disjointed point solutions. Despite this understanding, practical implementation remains fragmented, as organizations on average, still utilize more than 10 different tools to manage data security.

Breaking this inertia to better protect data requires strong collaboration among security teams, prioritizing the overall data security posture of the organization over individual and departmental security use cases. It also calls for better-integrated solutions to bring this collaborative approach to life.

Fortifying data security with integrated solutions

An integrated data security solution set should empower security teams to do all these critical tasks seamlessly:

Enabling security teams to do all these critical tasks seamlessly has been the primary focus for Microsoft Purview. These solutions leverage the same industry-leading,1 AI-powered data classification technology, data map, extensive audit logs and signals, and management experience. As a result, the data security solutions seamlessly integrate with each other, aiding organizations in protecting their data with lower complexity and better outcomes.

To give you a real-world example, we dissected a corporate espionage incident inspired by a true story to demonstrate how taking an integrated approach can help detect and prevent such incidents that may otherwise have gone unnoticed.
