Business Data Assets: Essential Tips For Resilient Security

Data is the centerpiece of current and future business operations: innovation, strategic decision-making, and growth. However, these very digital advances that empower organizations—precisely the source of advantage—are simultaneously exposing them to another ever-growing array of cyber threats. 

From sophisticated ransomware attacks and data breaches to insider threats, the risks to valuable business information are escalating.

To stay competitive and protect their operations, companies must prioritize implementing robust security measures. This involves protecting against current threats and anticipating and adapting to future risks. A proactive and comprehensive approach to data security allows businesses to ensure the confidentiality, integrity, and availability of their critical information. 

This approach fosters trust with customers and stakeholders while mitigating the potentially devastating consequences of data loss or compromise. 

What is a data asset?

Data assets, encompassing any system, file, document, database, or website, play a strategic role in companies' revenue generation. These assets are not just valuable resources, but the backbone of business operations, prompting businesses to invest significant resources in their effective management. 

Proper asset management empowers companies, enabling them to gain a deeper understanding of markets and customers and discover new revenue opportunities.

These data assets are not just passive resources, but catalysts for innovation and growth. They contribute to creating new offerings, enhancing existing products, and adding value for customers. 

Companies actively gather, compile, and store data on various market information, transactions, and events impacting their business. Commonly, companies maintain customer data, including information on customer behaviors, spending patterns, budgets, and other metrics. 

This data is then transformed into actionable insights, sparking innovation and helping companies improve customer service and gain a competitive edge in the market.

Conduct a Comprehensive Risk Assessment

​A thorough risk assessment forms the foundation of any resilient data security strategy. This process involves a systematic evaluation of your current security posture, identification of potential vulnerabilities and threats, and prioritization of risks based on their potential impact.

To initiate the assessment, start by identifying all your data assets, including structured data (e.g., databases, spreadsheets), unstructured data (e.g., emails, documents), and semi-structured data (e.g., XML, JSON). Next, evaluate the current security measures safeguarding these assets, including encryption, firewalls, access controls, and intrusion detection systems.

Once you have a clear understanding of your assets and controls, identify potential threats. These could include external threats (e.g., cyberattacks, malware) and internal threats (e.g., accidental data leakage, malicious insiders). Analyze vulnerabilities within your systems, networks, and processes that could be exploited by these threats.

When you're dealing with technical problems during an assessment, having a dependable support team can be a game-changer. For instance, the computer support team at Revotech, among others, is known for their prompt and efficient service, ensuring that any technical hurdles encountered during the risk assessment are swiftly addressed.

Implement Strong Access Controls

One of the most effective access control measures is multi-factor authentication (MFA). MFA enhances security by requiring users to present different types of authentications to access a system. These factors typically include something you know (like a password), something you have (such as a one-time code sent to your mobile device), and something you are (like a fingerprint). 

This significantly enhances security compared to single-factor authentication, which relies solely on a password.

Role-based access controls (RBAC) are key to a strong access control strategy. By assigning permissions according to each user's role within the organization, RBAC ensures employees can only access the data and systems relevant to their job responsibilities. 

This approach minimizes the risk of both accidental and intentional misuse of sensitive information. For example, a sales representative might have access to customer data but not financial records, while a finance manager would have access to financial records but not customer data.

In addition to internal measures, consider partnering with external experts to enhance your access control capabilities. There are various managed IT services available, such as those provided by local firms, online consultants, and services by Generation IX. 

These services can assist with the implementation and management of complex access control systems, ensuring that your data remains secure and compliant with industry regulations.

Encrypt Sensitive Data

Encrypting sensitive data is a crucial part of keeping your business information safe and secure. 

Data encryption protects data both at rest (stored data) and in transit (data being transmitted) from unauthorized access, ensuring that even if it is intercepted or accessed, it remains unreadable to unauthorized parties.

Encrypt Data at Rest and In Transit​

​Encrypting data at rest means applying encryption protocols to information stored on hard drives, databases, and other storage media. 

This prevents unauthorized individuals from accessing the data even if they manage to bypass other security measures. For instance, if a company's server is compromised, encrypted data will be unreadable without the proper decryption keys.

Similarly, encrypting data in transit is crucial. This involves encrypting data as it moves between systems, such as during email communications, file transfers, or web browsing sessions. 

By using secure communication protocols like HTTPS, SSL/TLS, and secure email gateways, you can protect your data from being intercepted by malicious actors while it's being transmitted.

Use Industry-Standard Encryption Protocols and Secure Keys

When implementing encryption, it is essential to use industry-standard protocols, such as Advanced Encryption Standard (AES) for data at rest and Transport Layer Security (TLS) for data in transit. 

These protocols are widely recognized for their effectiveness in protecting sensitive information.

Additionally, managing and securing encryption keys is paramount. The strength of your encryption depends on how well these keys are protected. 

Store encryption keys in secure hardware security modules (HSMs) or use key management services (KMS) that offer robust protection against unauthorized access. 

Regularly Update Encryption Methods

The landscape of cybersecurity threats is continuously evolving, with new vulnerabilities and attack methods emerging regularly. Therefore, it is crucial to stay ahead of these threats by regularly updating your encryption methods. This means keeping your encryption software and protocols up to date, following the best practices for cryptographic algorithms, and switching to stronger encryption standards as they become available.

For example, transitioning from older encryption standards like DES (Data Encryption Standard) to more robust protocols like AES-256 can significantly enhance the security of your data. Regularly auditing and updating your encryption strategy ensures that your data remains protected against the latest threats. 

Ensure Compliance with Regulations

​Businesses must continuously monitor and understand the data security regulations relevant to their industry and location. For example, GDPR (General Data Protection Regulation) governs the processing of personal data for individuals within the European Union, imposing strict requirements on how data is collected, stored, and processed. Compliance with GDPR involves implementing measures such as obtaining explicit consent for data collection, ensuring data portability, and maintaining the right to erasure.

Similarly, HIPAA (Health Insurance Portability and Accountability Act) sets standards for protecting sensitive patient information in the healthcare sector. Compliance requires implementing administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of electronic protected health information (ePHI). This includes conducting risk assessments, establishing access controls, and providing regular employee training on data privacy.

Conducting internal and external audits can provide a comprehensive evaluation of an organization's compliance status. Internal audits involve assessing current policies, procedures, and practices against regulatory requirements, while external audits, conducted by third-party experts, offer an unbiased evaluation of compliance efforts.

Also, using compliance management software can streamline the audit process by automating the tracking and reporting of compliance activities. This software can generate real-time reports, track remediation efforts, and ensure that all regulatory requirements are met.
