Increasing Secure Score—a widely-recognized cybersecurity metric found within the popular Microsoft Defender 365 solution—ensures compliance with these regulations by implementing recommended security controls and best practices. Beyond legal compliance, a high Secure Score means the company is protecting itself from potentially harmful and expensive cyber attacks, saving valuable time, money, and brand reputation.

The case study documents the dramatic increase one automobile software solution company realized in its Secure Score with the help of Cprime consultants: from 44.24% to 85.19%.

Driving Toward More Secure Automotive Software

A leading automobile software solution company wanted to boost customer confidence, and protect data and system security by enhancing its Secure Score within Microsoft Defender 365. Secure Score is a pivotal metric reflecting an organization’s security posture, measured through the implementation of recommended security actions.

Why would a company want to increase its Secure Score?

An automotive software company, like any other organization, would have several compelling reasons to increase its Secure Score in Microsoft 365. Here are some key motivations:

• Protection of Sensitive Data: Automobile companies deal with a vast amount of sensitive data, including proprietary designs, customer information, and manufacturing processes. Enhancing Secure Score helps in safeguarding this data against unauthorized access, data breaches, and cyber threats. 
• Regulatory Compliance: The automotive industry is subject to various regulatory frameworks, such as GDPR, HIPAA, and ISO standards. Increasing Secure Score ensures compliance with these regulations by implementing recommended security controls and best practices.
• Prevention of Intellectual Property Theft: Automobile companies invest heavily in research and development to innovate new technologies and designs. A higher Secure Score mitigates the risk of intellectual property theft by strengthening data protection measures and access controls.
• Protection of Customer Trust: Automobile companies rely on customer trust and loyalty to maintain their market position. By increasing Secure Score, companies demonstrate their commitment to safeguarding customer data and protecting their privacy, thereby enhancing brand reputation and trust.
• Mitigation of Operational Risks: Cyberattacks and data breaches can disrupt manufacturing processes, supply chains, and customer services, leading to significant operational and financial losses. Improving Secure Score helps in mitigating these risks by fortifying security defenses and incident response capabilities.
• Partnership and Supplier Requirements: Automobile companies often collaborate with various partners, suppliers, and vendors across the supply chain. Increasing Secure Score may be necessary to meet contractual obligations, security requirements, and third-party audits imposed by partners and suppliers.
• Competitive Advantage: In today’s digital landscape, cybersecurity is increasingly becoming a differentiator for businesses. Automobile companies with a high Secure Score can leverage this as a competitive advantage to win contracts, partnerships, and customers who prioritize security in their procurement decisions.

For organizations with a low Secure Score, there’s a pressing need to bolster their defenses and elevate their Secure Score to a level where they are less vulnerable to cyber threats. Achieving a higher Secure Score not only signifies a stronger security culture but also reduces the organization’s susceptibility to various cyber threats such as data breaches, malware attacks, and phishing attempts—enhancing their resilience and minimizing the risk of being targeted by malicious actors.

Increasing the Secure Score involves implementing additional security controls, adhering to best practices, and addressing vulnerabilities across different domains such as identity management, data protection, threat detection, device security, and application security. 

Ultimately, the goal is to elevate the Secure Score to a number where the organization is not only better protected against potential threats but also meets industry standards and benchmarks for cybersecurity. This proactive approach promotes confidence among stakeholders, customers, and partners in the organization’s ability to protect their interests even as cyber threats grow.

The Story

When this automotive supplier called Cprime in to assist, they were at a baseline Secure Score of 44.24 percent—a number right in line with most software organizations in the automotive and similar industries. It indicated they had taken many of the usual steps to make their systems secure, but that there was plenty of room for improvement; there was still a significant gap in the overall security posture.

The Goal: Raise the Secure Score to 75% or Better

The primary objective was to elevate the Secure Score to the maximum achievable number, signifying robust implementation of security controls and adherence to industry best practices. An initial goal was 75%, which would have put this automotive supplier ahead of most organizations in their industry. We also established a stretch goal of 85%, seeking out as many value-add improvements as we could reasonably make. 

Methodology and Action

Collaborating with stakeholders at the company, Cprime consultants followed a structured approach to enhance their Secure Score:

1. Assessment and Analysis: Comprehensive evaluation of existing security configurations to identify vulnerabilities and gaps.

2. Secure Score Benchmarking: Comparison of Secure Score against industry standards and Microsoft recommendations to determine necessary improvements.

3. Prioritization: Determining which improvements were both immediately doable and would have the greatest impact on improving the Secure Score, allowing us to affect the greatest improvement as quickly as possible.
4. Recommendation Implementation: Diligent execution of recommended security enhancements across various domains including Identity, Data, Devices, Infrastructure, and Apps.

5. Policy Enforcement: Implementation of stringent security policies governing access control, data handling, and incident response.

Here is an example of one of the areas to be addressed to achieve the 85% Secure Score. 

Security Improvement in Action

The following recommendations were targeting ‘Microsoft Entra ID’ the Identity and Access avenue of an organization.

In order to achieve robust security in this area, we followed the recommendations and implemented nine policies governing things like multifactor identification, personal device usage, and strictly limiting admin access.

As a result, we achieved a 100% Score on the Identity.

We enforced the following Data Protection Policies to achieve a 100% Score on Data as well:

• Data Encryption: All sensitive data, both in transit and at rest, is encrypted using industry-standard encryption algorithms. This includes data stored in databases, files shared internally or externally, and data transmitted over networks.
• Data Classification: A data classification policy is implemented to categorize data based on its sensitivity level (e.g., public, internal, confidential, or restricted). This helps in applying appropriate security controls and access restrictions based on the sensitivity of the data.
• Data Retention and Disposal: A data retention policy defines how long different types of data should be retained based on regulatory requirements, business needs, and legal obligations. Data that is no longer required is securely disposed of using methods such as shredding or secure deletion.

Data Loss Prevention (DLP): DLP policies are implemented to prevent the unauthorized sharing or leakage of sensitive data. This includes monitoring outbound communications, detecting sensitive data patterns, and blocking or alerting on unauthorized data transfers.

In all, we made improvements across all the Secure Score components:

• Identity: Strengthened authentication mechanisms, enforced multi-factor authentication, and minimized privileges. (From 35.25% to 100% Secure Score)
• Data: Enhanced data encryption, implemented data loss prevention policies, and restricted unauthorized access. (From 1% to 100% Secure Score)
• Devices: Enforced device encryption, deployed endpoint detection and response solutions, and ensured compliance with security baselines. (From 43.79% to 70.08% Secure Score)
• Apps / Infrastructure: Strengthened application security, enforced secure coding practices, and conducted regular vulnerability assessments. Improved network security, implemented robust firewall configurations, and enhanced server hardening measures. (From 66.06% to 87.88% Secure Score)
