Remote Work Security Essentials

Remote work offers flexibility but creates security challenges. Without the controlled environment of an office, protecting sensitive data requires intentional practices.

The Remote Work Security Challenge

When you work from home or anywhere else, you lose:

• Secure corporate network
• IT-managed equipment
• Physical security controls
• Immediate IT support
• Controlled environment

You must replace these with personal security practices.

Securing Your Home Network

Router Security

Your router is your first defense:

Network Segmentation

If possible, separate work from personal:

• Use different Wi-Fi networks
• Consider a dedicated work VLAN
• Keep IoT devices isolated

Device Security

Computer Security Basics

Mobile Device Security

Your phone likely has work data too:

• Enable device encryption
• Use biometric + PIN
• Keep apps updated
• Review app permissions
• Enable remote wipe
• Avoid unknown app sources

Physical Security

Even at home:

• Lock screen when stepping away
• Secure devices when not in use
• Shred sensitive documents
• Be aware of who can see your screen
• Secure devices during travel

Using VPNs

When You Need a VPN

• Using any public Wi-Fi
• Accessing company resources
• Working with sensitive data
• When required by policy

VPN Types

Corporate VPN:

• Connects to company network
• Required for internal resources
• IT manages and monitors

Personal VPN:

• Encrypts your connection
• Hides activity from ISP
• Good for public networks

Public Wi-Fi Precautions

If you must use public Wi-Fi:

1. Always use VPN - Non-negotiable
2. Verify the network - Confirm with staff
3. Avoid sensitive work - If possible
4. Use HTTPS - For all browsing
5. Disable auto-connect - Join manually
6. Forget network after - Don’t save it

Better Alternatives

• Mobile hotspot from your phone
• Portable hotspot device
• Work from secure locations only

Password & Authentication

Password Best Practices

• Use a password manager
• Generate unique, strong passwords
• Never reuse passwords
• Don’t store in browsers (use manager instead)

Two-Factor Authentication

Enable 2FA on everything:

• Email accounts
• Cloud storage
• Communication tools
• Financial services
• Social media

Without 2FA, a stolen password gives attackers complete access. With 2FA, a stolen password is just the first step in a much harder attack.

Secure Communication

Video Calls

• Use waiting rooms
• Require passwords
• Don’t share meeting links publicly
• Be aware of screen sharing
• Check who’s in the meeting
• Consider background/surroundings

Messaging

• Use approved tools only
• Understand encryption levels
• Don’t share credentials via chat
• Be wary of unexpected links
• Verify unusual requests

Email

• Watch for phishing attempts
• Verify sender addresses
• Don’t open suspicious attachments
• Use secure alternatives for sensitive data

Data Protection

Classification

Know what you’re working with:

Classification	Examples	Handling
Public	Marketing materials	Normal care
Internal	Procedures, policies	Reasonable protection
Confidential	Client data, financials	Encryption, access controls
Restricted	Credentials, PII, health data	Maximum protection

Backup

Ensure your work is protected:

• Regular automated backups
• Encrypted backup storage
• Test restoration periodically
• Don’t rely on single copies

Cloud Storage

When using cloud services:

• Use approved services only
• Check sharing settings
• Don’t sync sensitive data to personal accounts
• Understand where data is stored

Environment Awareness

Working in Public

• Position screen away from observers
• Use privacy screen if needed
• Be careful with phone calls
• Don’t leave devices unattended
• Lock up when you leave

Working at Home

• Secure home office if possible
• Be aware of video call backgrounds
• Keep work documents secured
• Consider family member access

Incident Response

What to Do If

You click a phishing link:

1. Disconnect from network
2. Don’t enter any credentials
3. Run malware scan
4. Report to IT/security
5. Monitor accounts

Your device is lost/stolen:

1. Attempt remote wipe
2. Report immediately
3. Change relevant passwords
4. Monitor for unauthorized access

You suspect compromise:

1. Stop using affected systems
2. Document what happened
3. Report immediately
4. Follow security team guidance

Building Good Habits

Security isn’t a one-time setup—it’s daily habits:

Daily

• Lock screen when away
• Verify unusual requests
• Use VPN on untrusted networks

Weekly

• Review account activity
• Update software
• Check for unusual behavior

Monthly

• Review access and permissions
• Update passwords as needed
• Security training/awareness

Company Resources

Know what support is available:

• IT helpdesk contact
• Security team contact
• Incident reporting process
• Approved tool list
• Security policies

Conclusion

Remote work security ultimately comes down to treating your home office with the same security mindset as a corporate office—while accepting that you’re now the IT department.

Focus on:

• Secure network and devices
• Strong authentication
• Safe communication practices
• Data protection awareness
• Good daily habits

The effort invested in security protects not just company data, but your clients’ information, your reputation, and your continued ability to work remotely.
