Creating Separate Work and Personal User Profiles

Mon, 07 Apr 2025 17:57:49 -0400

At Buffalo Sentinel, we take cybersecurity seriously—especially when it comes to protecting sensitive data and meeting regulatory requirements like the New York Department of Financial Services (NY DFS) 23 NYCRR 500. One simple but powerful practice we encourage all clients and internal users to adopt is creating separate user profiles for work and personal use on their computers.

Here’s why it matters and how to do it right.

Why Separate User Profiles Matter

Most cybersecurity incidents stem from human error: clicking on a phishing link, downloading an unsafe file, or mixing personal and business data. Having distinct work and personal user profiles helps mitigate these risks by:

Isolating business-critical apps and data
Reducing the attack surface of sensitive systems
Maintaining a clear audit trail for compliance and monitoring
Supporting role-based access control (RBAC) with more precision

This approach aligns directly with NY DFS’s mandates for access controls, audit trails, and data protection.

"But We're Small" Doesn't Exempt You

It’s a common misconception that small businesses or solo practitioners are exempt from cybersecurity regulations. That’s simply not the case.

NY DFS Cybersecurity Regulation (23 NYCRR 500) applies to all covered entities, regardless of size. Whether you’re a solo financial advisor, a boutique insurance agency, or a startup fintech firm—you are still expected to implement robust cybersecurity controls.

The regulation recognizes that threats can come from anywhere, and even one compromised account can lead to a breach that triggers reporting obligations, fines, and reputational damage.

Pro tip: Creating distinct user profiles is a low-cost, high-impact way to begin aligning with compliance—no expensive software required.

Step-by-Step: Creating Two User Profiles

Whether you're on Windows, macOS, or a Linux-based system, the steps are similar:

1. Create a Work Profile

This account will:

Have elevated privileges only as needed (e.g., admin tools for MSP techs)
Be governed by cybersecurity policies (enforced through Group Policy or MDM)
Include business apps only: RMM agents, ticketing systems, finance apps, etc.
Enforce strong authentication: password + MFA (multi-factor authentication)

2. Create a Personal Profile

This account should:

Be non-admin
Have restricted access to any work folders or software
Be used only for personal browsing, media, or email
Be sandboxed with browser isolation or application control if possible

Implementing Policies & Controls

Once the two profiles are created, apply the following policies and controls:

Access Controls

Use least privilege principles on both profiles.
Prevent the personal profile from accessing mapped business drives or software.

Application Whitelisting

On the work profile, only allow business-critical software.
Block installers and unknown executables via software restriction or AppLocker.

Audit & Monitoring

Log login events and application usage on the work profile.
Use your RMM or SIEM to set alerts for anomalies (logins at odd hours, failed MFA attempts).

Data Protection

Enable BitLocker or FileVault for full-disk encryption.
Block USB drives or encrypt them by policy.
Prevent clipboard sharing between user profiles (especially in virtualized environments).

Personal Device Use (BYOD)

If a personal device is being used for business, Buffalo Sentinel recommends:

Using a VDI (Virtual Desktop Infrastructure) or secure browser session instead of local apps.
Separating business and personal spaces with MDM tools like Microsoft Intune or Zoho Endpoint Central.

Staying NY DFS Compliant

These user profile strategies help directly with several NY DFS Cybersecurity requirements, including:

NY DFS Section	Compliance Area	How This Helps
500.3	Cybersecurity Policy	Supports access control and device security
500.7	Access Privileges	Enforces least privilege for each profile
500.12	Multi-Factor Authentication	Enables profile-specific MFA
500.13	Limitations on Data Retention	Keeps business data out of personal use areas
500.14	Training and Monitoring	Enables better tracking and user awareness

Final Thoughts

At Buffalo Sentinel, we don’t just secure systems—we empower users to build strong digital habits. By simply separating work and personal activity, you create a security buffer that protects your business and helps you stay in full compliance with NY DFS regulations.

Why You Should Think Twice About Using In-Browser Password Managers

Mon, 31 Mar 2025 21:40:47 -0400

Most modern browsers—like Chrome, Edge, Safari, and Firefox—offer built-in password managers. They prompt you to save your login credentials, autofill them on future visits, and even generate strong passwords. It sounds convenient, right? But here’s the problem: convenience often comes at the cost of security.

Let’s dig into why relying on your browser’s built-in password manager might not be the safest choice—and look at better alternatives like Bitwarden, Proton Pass, and 1Password.

The Problem with In-Browser Password Managers

Browser-based password managers are designed for ease-of-use, not enterprise-grade security. While they do provide encryption and syncing across devices, they’re often deeply integrated into your browser profile—making them a prime target for attackers.

Here’s how your passwords can be stolen:

Malware like RedLine or Raccoon can extract browser-stored credentials in seconds.
Profile theft allows an attacker to clone your browser and access everything you’ve saved.
JavaScript injection by shady extensions or compromised websites can grab autofilled credentials.
Weak encryption linked to your device login means if someone gets access to your PC, your passwords are exposed.

Need Help Making the Switch?

Bitwarden

An open-source, end-to-end encrypted password manager. Offers browser extensions, secure sharing, TOTP, and even self-hosting.

Proton Pass

Built by the privacy-first Proton team, this manager offers advanced encryption and protects even metadata (who you log in as, where, when).

1Password

Popular with both individuals and businesses. Features include breach monitoring, secure vaults, Travel Mode, and biometrics.

Each of these tools:

Encrypts data before it leaves your device.
Never stores plaintext passwords.
Supports MFA and password health reports.
Works across browsers, phones, and operating systems.

Safer Alternatives: Use a Dedicated Password Manager

If you're currently relying on your browser's built-in password manager and aren’t sure how to disable it or migrate your data safely—you’re not alone.

Buffalo Sentinel can help you:

Disable password saving in Chrome, Edge, Firefox, and Safari.
Export your saved passwords securely.
Set up and configure Bitwarden, Proton Pass, or 1Password.
Train your team on best practices for password hygiene.

Got Infected? We’ve Got Your Back

If you ever do get infected by malware or spyware designed to steal browser-stored credentials, Buffalo Sentinel can help detect it fast.

With advanced Endpoint Detection and Response (EDR) tools and a Security Information & Event Management (SIEM) platform, we monitor for:

Suspicious password extraction behavior
Malicious command-line tools (like LaZagne or Mimikatz)
Unusual login patterns or data exfiltration
Indicators of compromise in real time
Early detection means faster response—and less damage.
