Data Security Measures to Protect Your Organization

Data protection has become a critical component of business strategies across all industries, regardless of company size. In numerous countries, it’s now a legal requirement. Legislation such as the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) govern the collection, processing, and storage of personally identifiable information (PII) such as names, addresses, and phone numbers, granting various rights to data subjects.

In a world where cyber-attacks are expanding and supply chain breaches are common, protecting your organization’s network, data, and reputation is crucial.

What are data security measures? 

Data security measures are a range of processes and tools aimed at protecting sensitive assets. From secure data creation to real-time monitoring and swift response to suspicious activities, effective data security measures are comprehensive and adaptable.

These measures aren’t just about defending against external threats. They also play a critical role in mitigating internal risks and safeguarding intellectual property. Whether you’re a small startup or a large enterprise, the principles of data security remain essential.

Embracing best practices such as encryption, access controls, and regular audits can enhance your defenses and minimize the impact of potential security incidents.

So why is data security so critical that authorities and regulators consistently introduce new data security requirements?

Your organization must protect sensitive data in line with relevant industry and jurisdictional laws and regulations.

Top 7 Data Security Measures Your Business Needs

Here are ten essential security measures that organizations must prioritize to ensure the security of their systems:

1. Access Control

Access control forms the foundation of security measures. Whether setting up an account, system, or database, it’s crucial to ensure that access is restricted to authorized users only. The principle of least privilege should guide access control, ensuring users are granted the minimum permissions required to perform their tasks. 

Implementing Access Control Lists (ACLs) helps regulate access to resources by defining roles assigned to users, thus controlling access based on predetermined rules. Utilizing ACLs not only secures vital data but also helps manage network traffic effectively. Additionally, monitoring privileged user accounts closely and revoking access during off-boarding processes are critical steps to prevent insider threats and unauthorized data access.

2. Password Protocol

The primary risk associated with stolen or compromised passwords is identity theft. Therefore, maintaining password hygiene is crucial. While managing passwords may pose a challenge, they remain a fundamental aspect of security. The rule is simple: the more complex and robust the passwords, the harder they are to crack. 

Passwords should include a mix of characters, numbers, and symbols while remaining memorable. We also advise using unique passwords for each website or account to enhance security. Unfortunately, password hygiene doesn’t end there. Studies show that over 41% of employees admit to sharing passwords, which not only compromises security but can also lead to severe consequences. Hence, it’s vital to enforce strict password-sharing policies.

3. Data Detection and Classification

As companies evolve, they handle increasingly diverse types of data, leading to challenges in tracking and protecting assets. This is especially critical for sensitive information like Protected Health Information and Payment Card Information. 

The best solution to this issue is data classification. While data detection identifies the presence and location of data, data classification categorizes it based on sensitivity, value, and access level. Various models, including content-based, context-based, and user logic-based classification, are used for this purpose. Data detection and classification empower organizations to control data access, understand risks, and focus their data security efforts effectively.

4. Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA) is an authentication method that requires users to confirm their identity through two or more instances. It serves as a safety net for password mechanisms, providing layered defense against unauthorized access. MFA is a vital component of Identity and Access Management (IAM) strategies and is mandated by security regulations like HIPAA. 

Its numerous advantages, including ease of setup and adaptability, make it indispensable. By reducing data breaches significantly compared to passwords alone, MFA is a crucial security measure. Despite its benefits, a recent study found that only 58% of organizations use MFA, with 32% offering it as an optional feature, a trend expected to rise.

5. Application Security

Web applications face specific security vulnerabilities, including broken access, misconfigurations, and authentication errors, leaving them susceptible to threats like SQL injection attacks. 

Application security involves consistently testing, reporting, and enhancing security features within an application to identify and mitigate vulnerabilities against potential threats. These measures include securing apps at a code level and conducting testing exercises to assess their response to non-typical inputs, preparing security teams to address threats effectively.

6. Disaster Recovery

Disasters, whether natural or otherwise, are inevitable. When systems and data become inaccessible due to events like natural disasters, cyberattacks, or equipment failures, businesses must minimize disruption. 

A disaster recovery plan involves assembling a team of security personnel to execute predefined roles during security events. This plan includes risk and impact assessment and outlines steps to restore normalcy and ensure business continuity by accessing data backups and implementing recovery mechanisms.

7. Security Patch Management

Maintaining system patches and updates is essential for enterprise security. Patch management involves identifying, testing, and installing patches on software and firmware to address errors, bugs, or vulnerabilities. 

In terms of data security, patches play a crucial role in reducing the organization’s attack surface. Effective patch management ensures applications and systems remain up-to-date and function smoothly. Moreover, security patches provide access to enhanced security features and facilitate compliance adherence.

5 Ways Large Enterprises Protect Their Data

While large companies are often ahead in the data protection realm, having established and tested security policies over the years, their requirements are also more intricate. Many must safeguard additional categories of data beyond customer information, such as intellectual property and financial data. Let’s delve into the most effective strategies employed by organizations to protect their data and ensure corporate data security.

1. Employee Education at All Levels

The human element often represents the most significant vulnerability in the data protection chain. Large corporations prioritize employee awareness of compliance regulations and best security practices by providing comprehensive training and clear guidelines, especially for those handling sensitive data.

C-suite executives are frequent targets for malicious attacks due to their high-level access to data. Hence, big companies take proactive measures to ensure that top management adheres to security protocols, maintaining consistent data security standards across all organizational levels.

Data Loss Prevention (DLP) solutions serve as effective enforcement tools by establishing clear policies that protect and limit access to sensitive data. Access levels can be managed based on user groups, departments, specific individuals, or endpoints.

2. Data Visibility and Management

A critical aspect of effective data protection is comprehensive knowledge of the data being stored and its destinations. By accurately identifying the data lifecycle and associated security risks, organizations can make informed decisions regarding necessary protective measures.

Large enterprises utilize Data Loss Prevention (DLP) tools like Endpoint Protector to scan company networks for sensitive data. Upon detecting such data in unauthorized locations, they can opt to delete or encrypt it. In the era of stringent data protection regulations, transparency is imperative for both compliance and the establishment of robust data protection policies.

3. Enhanced Defense Against External Threats

To combat external security threats, major corporations employ and regularly update fundamental measures like two-factor authentication, firewalls, and antimalware solutions. Additionally, they delve deeper by incorporating more sophisticated strategies such as Trusted Platform Module (TPM) capabilities and embracing Zero Trust architecture.

Zero Trust architecture introduces a novel approach to cybersecurity: never trust, always verify. It ensures that users, devices, and network traffic undergo verification and adhere to least-privilege rules when accessing trusted resources. Consequently, if one device becomes compromised, attackers are thwarted from traversing the network laterally.

4. Universal Encryption Implementation

Encryption has become indispensable for safeguarding sensitive company data and securing customer information across various platforms. From encrypted hard drives, USBs, and smartphones to data encrypted prior to transmission to the cloud or portable devices, encryption ensures comprehensive protection against unauthorized access and data breaches.

Encryption addresses two prevalent data protection vulnerabilities in today’s global economy: a mobile workforce and the surge in remote work. As devices frequently leave the safety of company networks, encryption ensures that sensitive data stored on them remains inaccessible to unauthorized individuals in the event of theft or loss.

5. Establishment of BYOD Policies

While Bring-your-own-device (BYOD) policies enhance productivity and reduce costs, they often overlook security implications. Accessing sensitive information on personal devices exposes data to risks outside the company network, undermining existing security measures.

Large organizations mitigate these risks by restricting the types of data that can be transferred to personal devices. Additionally, device control policies are enforced to ensure that only secure devices are permitted access. Employees are given the option to align the security of their personal devices with company standards, ensuring that sensitive data remains protected. 

As we advance into the era of data protection by design and default, mid-sized and small businesses must emulate larger enterprises by implementing robust security measures to safeguard data from both internal and external threats.

To wrap up

While the digital landscape poses challenges, proactive data security measures offer a path forward. By investing in the right tools and strategies, you can protect your organization’s most valuable assets and maintain its reputation in a constantly evolving threat environment.
