⁠How to Ensure Better Data Security in Your Enterprise

Nowadays, data is the lifeblood of most enterprises. It fuels innovation, drives business decisions, and fosters communication with customers and partners. However, with this growing dependence on data comes a heightened vulnerability: the ever-present threat of cyberattacks and data breaches to both businesses and network infrastructure.

Data breaches can be devastating. Financial losses from cleanup, regulatory fines, and litigation can be considerable. Damage to customer trust and future business partnerships can also be severe. This guide will equip you with the knowledge and strategies to ensure better enterprise data security.

Different Types of Enterprise Data

Not all data within an enterprise is created equal. Understanding the various types of data you hold is the first step toward effective data security.

1. Sensitive data - This includes information that could cause significant harm if exposed, such as financial records, personally identifiable information (PII) like Social Security numbers or passport details, and intellectual property.

2. Confidential data - This includes information that should be kept private within the organization, such as internal communications, strategic plans, and customer lists.

3. Public data - This refers to information that is freely available to the public, such as company press releases or product information on a website. While it may not require the same level of security as sensitive data, maintaining its integrity is still important.

What is Data Security?

Throughout its entire lifetime, data security protects against hacking, theft, unauthorized access, and improper use. A combination of technologies, standards, and best practices that keep data secure, private, and accessible provide this protection.

Some of the most important parts of data security are WPA3 encryption, multi-factor authentication (MFA), access controls, firewalls, and regular security checks. Many routers include built-in firewall or encryption capabilities that monitor incoming and outgoing traffic. Effective data security helps keep private information safe, makes sure companies follow the rules, and prevents financial and reputational damage to businesses.

Common Threats on Data Security

You should also be aware of the ever-evolving threats that can compromise its security. Here are some of the most common data security threats faced by enterprises today:

1. Malware - This malicious software encompasses viruses, worms, ransomware, spyware, and more. Malware can steal data, disrupt operations, or gain unauthorized access to systems.

2. Phishing Attacks - These deceptive attempts aim to trick users into revealing sensitive information through emails or fraudulent websites that mimic legitimate sources.

3. Insider Threats - Disgruntled employees, negligent practices, or weak access controls can all lead to data breaches by insiders, whether malicious or unintentional.

4. Social Engineering - Attackers leverage psychological manipulation to deceive individuals into compromising data security. This can involve impersonating trusted entities, exploiting fear or urgency, or creating a false sense of security.

5. Unsecured APIs - Application Programming Interfaces (APIs) provide programmatic access to data and functionality. Unsecured APIs can be exploited by attackers to gain unauthorized access to sensitive information.

6. Denial-of-Service (DoS) Attacks - These attacks overwhelm a system with traffic, rendering it unavailable to legitimate users.

7. Unpatched Software - Outdated software with known vulnerabilities creates a window for attackers to exploit these weaknesses and gain unauthorized access to systems.

Ways to Secure Enterprise Data

Having a robust data security strategy goes beyond simply understanding the threats. Here are key steps you can take to secure your enterprise data:

Data Classification and Inventory

Data security starts with knowing what data you have and how sensitive it is. Inventory every piece of information in the company, including databases, file servers, laptops, and cloud storage. Categorize this material as high-risk (financial records, PII), medium-risk (internal communications), or low-risk. This classification lets you prioritize resources and adjust security.

Cybersecurity Policy

A well-defined cybersecurity policy tells everyone in your company how to handle data safely. This policy should clearly outline acceptable data practices, such as refraining from storing private data on your own devices or sharing it with unauthorized individuals.

Access Controls

Strong passwords should include minimum character length, complexity (a combination of capital and lowercase letters, digits, and symbols), and regular password changes. Multi-factor authentication (MFA) enhances security by requiring a second verification step like a phone code or fingerprint scan.

Data Encryption

Encryption scrambles data into an unreadable format, rendering it useless to unauthorized individuals. Protecting data at rest (stored on servers or devices) and in transit (transmitted over networks) is crucial. The Advanced Encryption Standard (AES-256) is a widely used and highly secure encryption algorithm.

Regular Software Updates

Patch vulnerabilities in operating systems, applications, and firmware promptly. Automate software updates whenever possible to minimize the window of exploitability.

Network Security

Implement firewalls and intrusion detection/prevention systems (IDS/IPS) to monitor network traffic for suspicious activity and block malicious attempts in real-time. Regularly update firewall rules and IDS/IPS signatures to ensure they can detect the latest threats.

Secure Remote Access

For remote work, utilize Virtual Private Networks (VPNs) or a VPN router such as the Omada Pro 4G+ Cat6 AX3000 Gigabit VPN Router to create encrypted tunnels for secure data transmission. Implement MFA for additional security. Consider deploying zero-trust network access (ZTNA) solutions that grant access based on a user's identity and device health posture, further reducing the attack surface.

Data Backups and Recovery

Regularly back up critical data to a secure offsite location, geographically separate from your primary data center, to minimize the risk of data loss due to natural disasters or localized outages.

Empowering Users

Provide cybersecurity awareness training for all employees to educate them on best practices for password management, identifying phishing attempts, and reporting suspicious activity. Encourage employees to report suspicious behavior by fostering a culture of security.

Ongoing Monitoring and Threat Detection

Implement security information and event management (SIEM) systems to collect and analyze logs for potential security incidents. Conduct proactive threat hunting to identify and address emerging threats.

Incident Response Planning

Develop a documented plan outlining roles, communication protocols, and data recovery procedures to effectively respond to data breaches.

Other Steps To Properly Secure Your Data

1. Good Routers:

Good routers can enhance security features in many ways:

• Good WiFi routers for home or office have built-in firewalls that inspect incoming and outgoing traffic to prevent network intrusion. This protects against DDoS and intrusion attempts.
• High-quality routers offer WPA3, the latest and most secure wireless technology, which prevents unauthorized users from accessing Wi-Fi data.
• Modern routers allow users to set up guest networks, isolating devices on separate sub-networks. This protects sensitive data by limiting primary network exposure.
• Good routers frequently receive firmware updates from manufacturers to fix security vulnerabilities and ensure protection against newly discovered threats.

2. Fast Internet Connections:

• Although fast internet connection cannot directly protect data security, it can improve network performance, making firewalls, VPNs, and IDSs work better.
• Fast connections support efficient data encryption and decryption processes, which are important for secure communications, especially in real-time activities like video conferencing or large file transfers.
• Fast internet also expedites the download of software and security patches, reducing the duration of device vulnerability exposure.
