Connecting to a public network is a gamble with your data. Most people see free guest Wi-Fi as a convenience, but from a technical standpoint, it is a way for others to monitor your traffic. When you use these networks, you are trusting a third party to secure a connection that is often left intentionally wide open.
## The Reality of Network Interception
Most public access points are unencrypted. This means that any data sent between your device and the router is broadcast through the air in a format that is easily captured.
Malicious actors can use basic hardware to broadcast a network with a name that looks official. If a user connects to that hardware, every packet of data sent goes directly through a device controlled by a stranger. This includes login credentials, sensitive emails, and private documents. The tools to perform these interceptions are readily available and highly automated.
## Critical Vulnerabilities for Business Owners
For a business, the stakes are much higher than a compromised personal account. A single employee connecting to a public network can compromise the entire organization.
- **Credential harvesting** - Logging into a work portal on an unsecured network allows attackers to scrape usernames and passwords.
- **Interception attacks** - An attacker can position themselves between a computer and the website being visited. They can then serve a fraudulent version of a login page to steal information.
- **Malware distribution** - If a device on the network is already infected, some types of malware can move across the network to other connected devices without any user interaction.
## Applying This to Your Company
The goal is to empower staff with technology without creating unnecessary risks. Business owners want their teams to be productive, but it is also critical to maintain control over company data.
Follow these steps to secure remote operations:
- **Require a VPN** - A Virtual Private Network (VPN) creates an encrypted tunnel for data. Even if someone is monitoring the network, the information remains unreadable.
- **Prioritize cellular hotspots** - A phone's data connection is far more secure than public Wi-Fi. It is a better practice to have your team use their mobile hotspots for work tasks.
- **Mandate multi-factor authentication** - Multi-factor authentication (MFA) is a critical layer of defense. Even if a password is stolen on a public network, an attacker cannot access the account without the secondary verification code.
## Secure Your Infrastructure
Managing hundreds of accounts and keeping track of remote security is a significant task. However, ensuring data is protected allows a business to focus on actual operations. Technology should be a tool for success, not a source of constant worry.
If you need help auditing remote access policies or securing your team's devices, Cambium Data can provide a clear path forward.
