Hybrid work has transformed the manner in which businesses operate. No longer are employees restricted to the confines of the office. Instead, employees move between home environments, coffee shops, and corporate offices. Although this offers advantages for employees, such as increased productivity and job satisfaction, it introduces challenges for business information technology. Data that once remained secure within the corporate network is now spread across various environments, increasing the attack surface for data loss.

For companies that heavily utilize digital collaboration tools, data loss prevention demands a shift in approach. No longer is the focus solely on the corporate network. Instead, the entire attack surface must be considered.

Data Loss Risks in Hybrid Environments

For companies that maintain an office environment, the risks were always somewhat contained. A firewall and servers helped mitigate the data loss risks. However, with the shift to the hybrid environment, the entire paradigm has shifted. No longer do employees access the corporate network from within the office. Instead, they access it from residential Wi-Fi environments, which typically do not maintain the same level of security as the corporate environment.

Sadly, the risks are multifaceted. First, accidental deletion is a common issue. An employee may delete a file or folder that is important to the business. Second, malicious users are always a potential threat. A malicious user could gain access to the corporate network through a residential Wi-Fi environment. Finally, the loss of a laptop or other device can also lead to data loss if the device is not encrypted. The first step toward creating a robust data loss prevention system is to understand the risks.

Implementing Robust Endpoint Security

Employees now represent the new security perimeter; hence, endpoint security is essential. This means that every endpoint accessing the corporate network must be adequately secured. This goes beyond the standard antivirus solutions that most organizations implement. The latest endpoint detection and response solutions can help monitor every endpoint in real-time, detecting unusual behavior before it escalates into a security incident.

Another important security measure is encryption. This means that every laptop and mobile device should have full-disk encryption enabled. This way, the data remains secure even if the device falls into the wrong hands. Finally, implementing the multifactor authentication (MFA) process adds an extra layer of security. This acts as an additional measure, ensuring that even if the password is compromised, attackers would likely be unable to access the system without the other forms of identification.

Valuable Practices for Secure Cloud Storage

Cloud storage solutions and collaboration tools are the backbones of the hybrid work environment. However, many organizations operate under the misconception that the cloud providers handle the security of the data. While the providers manage the security of the underlying infrastructure, the responsibility for data retention lies primarily with the customer.

To address the risks associated with the cloud environment, the organization must develop its own data retention policies. This involves implementing an automated data backup solution for all critical data in the cloud environment.

For example, organizations that rely heavily on Microsoft’s tools should ensure that the data in Microsoft Teams, SharePoint, and Exchange environments is backed up separately. It is particularly important to backup Microsoft Teams data so that the business can continue smoothly even in the event of a Microsoft environment outage or a ransomware attack on the cloud.

Employee Training on Phishing Attacks

Technology alone is insufficient for addressing security risks. Human error remains a leading cause of data breaches. Phishing attacks continue to evolve, resembling internal communications or messages from the company’s executives. With the rise of the hybrid model, where physical verification is less common, employees might be more susceptible to these types of attacks.

Today, regular security awareness training is highly recommended. This includes teaching employees how to identify the nuances of phishing attempts. Conducting simulated phishing attacks can help measure the effectiveness of the training and identify areas where additional support may be required. When employees are empowered to be part of the defense team, the overall security strength of the organization improves.

Securing the Future of Hybrid Work

Preventing data loss in a hybrid setup is not a task that can be completed once but is rather an ongoing process. It requires a combination of technology, policies, and workforce engagement. Understanding the risks associated with a remote workforce, securing all endpoints, backing up data stored in the cloud, and educating employees are some of the steps that can help organizations enjoy the benefits of a flexible workforce without compromising their most important asset!
