Work From Home Security Checklist

This checklist gives you a structured, friendly, and actionable approach to securing your remote work environment. You’ll find practical steps, configurations, and habits that you can implement right away to reduce risk and maintain productivity.

Why Work From Home Security Matters

Working from home changes the security boundaries you’re used to in an office, and that expands the types of risks you face. You need to manage not only device and network safety, but also the human and physical factors that can lead to data loss or unauthorized access.

How to Use This Checklist

You can follow the checklist item-by-item, or use the quick-check tables to assess and prioritize what to fix first. Use notes in the tables to track progress and assign deadlines if you share security responsibilities with family members or coworkers.

Core Principles to Follow

Security should be layered so that a single failure doesn’t expose everything you own or manage. Apply the basics: strong authentication, regular updates, least privilege, encryption, and routine backups.

Least Privilege and Account Segmentation

Grant access only to what’s necessary for each account or service, and use separate accounts for personal and work tasks. This reduces blast radius if one account is compromised and helps you manage permissions clearly.

Defense in Depth

Implement multiple safeguards—like antivirus, firewalls, and MFA—so that if one control fails, others still protect you. Layering controls also helps you respond more effectively when incidents occur.

Network and Router Security

Your home router is the gateway between your devices and the internet, and it needs careful configuration. Make your router a hardened entry point by updating firmware, changing defaults, and isolating IoT devices.

Change Default Credentials

Default usernames and passwords on routers and IoT devices are widely known and exploited by attackers. You should set unique, strong passwords on the router’s admin interface and any networked device.

Keep Router Firmware Updated

Router firmware updates often patch security vulnerabilities that could let attackers into your network. Check the manufacturer’s website regularly and enable automatic updates if available.

Use Strong Wi‑Fi Encryption

Use WPA3 where supported, or WPA2-AES if necessary, and avoid older protocols like WEP or WPA-TKIP. This ensures that eavesdropping or casual Wi‑Fi attacks are much harder to execute.

Set Up a Guest Network

Create a separate guest network for visitors and IoT devices so your work devices remain isolated. This limits exposure if a smart device or visitor’s device is compromised.

Disable Unnecessary Services

Turn off WPS, UPnP, and remote management unless you explicitly need them, as they often introduce vulnerabilities. Reducing exposed services limits potential attack vectors.

VPNs and Secure Remote Access

Use a reputable VPN when accessing company resources or public Wi‑Fi, and prefer company-provided VPN solutions if your employer supplies one. A VPN encrypts traffic between your device and the network you use, helping protect credentials and data.

Choose a Trusted VPN Provider

Select a VPN with a strong privacy policy, no-logs practices, and modern encryption standards like AES-256. Corporate VPNs or reputable consumer VPNs with transparent practices are preferable.

Use Split Tunneling Carefully

Split tunneling lets you route some traffic directly to the internet while other traffic goes through the VPN, but it can expose work traffic if misconfigured. Only use it when you understand the trade-offs and your employer allows it.

Device Security and Management

Protect each device you use for work—laptops, desktops, tablets, and phones—with up-to-date security software and configuration. Device-level protection reduces the risk of malware and unauthorized access.

Keep Operating Systems Updated

Install OS updates promptly because they often include security patches for known vulnerabilities. Enable automatic updates where possible to avoid delays.

Use Endpoint Protection

Run reputable antivirus and anti-malware tools and configure them for real-time scanning. Endpoint protection helps detect and remove threats you might encounter through attachments or downloads.

Configure Device Encryption

Encrypt your device storage (FileVault on macOS, BitLocker on Windows, or native encryption on mobile devices) to protect data if your device is lost or stolen. Encryption makes it much harder for attackers to read your files.

Enable Secure Boot and BIOS/UEFI Passwords

Secure boot helps ensure only trusted software runs when your device starts, and a BIOS/UEFI password prevents some physical attacks. These controls raise the difficulty of tampering with your device.

Remove Unnecessary Software

Uninstall apps and services you don’t use to reduce the attack surface and minimize update workload. Fewer applications means fewer potential vulnerabilities to exploit.

Passwords and Authentication

Strong passwords and multi-factor authentication are foundational to protecting accounts and systems. Using unique passwords and MFA dramatically reduces the chance that a breached credential will lead to account takeover.

Use a Password Manager

A password manager helps you create and store complex, unique passwords for every account, and it simplifies login processes. Choose a well-known manager with strong encryption and a good reputation.

Implement Multi-Factor Authentication (MFA)

Enable MFA on all accounts that support it, especially email, cloud storage, and corporate systems. MFA adds a second barrier—like a code or hardware token—so attackers need more than a stolen password.

Prefer Authenticator Apps or Hardware Keys

Authenticator apps (TOTP) or hardware security keys (FIDO2/WebAuthn) are more secure than SMS-based codes, which can be intercepted. Use the strongest available second factor for important accounts.

Email and Phishing Defenses

Email is a top vector for attacks because attackers can trick you into clicking malicious links or sharing credentials. Building habits and using technical defenses will keep malicious messages from causing damage.

Learn to Spot Phishing

Look for misspellings, unusual sender addresses, pressure tactics, and unexpected attachments or links. When in doubt, verify by contacting the sender through a known channel.

Use Email Security Features

Use built-in email spam filters, link scanning, and attachment sandboxing if available through your provider. These features help block or flag suspicious messages before they reach you.

Avoid Clicking Unknown Links or Attachments

Don’t open attachments or click links from unknown or unexpected emails; instead, verify first. Even seemingly legitimate messages can be forged or compromised.

Cloud Storage and File Sharing

When you use cloud services, configure sharing settings carefully and track access to sensitive files. Secure cloud use prevents unwanted disclosure and unintended edits or deletions.

Use Strong Access Controls

Set files and folders to the least permissive sharing level required and review sharing permissions regularly. Use expiration links for temporary access and revoke permissions when no longer needed.

Enable Activity Monitoring and Alerts

Turn on activity logs or notifications where available so you can spot unusual access, downloads, or sharing. Early detection helps you respond quickly to potential breaches.

Encrypt Sensitive Files

Encrypt local copies of highly sensitive files before uploading when possible, and use services that offer end-to-end encryption for critical data. Encryption ensures that even if the file is accessed, its contents remain protected.

Backup and Recovery

Regular backups are essential so you can recover quickly from ransomware, hardware failures, or accidental deletion. Implement redundancy and test restores frequently to ensure backups work.

Follow the 3-2-1 Backup Rule

Keep at least three copies of important data, on two different media types, with one copy stored offsite or in the cloud. This strategy reduces the risk of total data loss.

Automate Backups

Automate backups to avoid human error and ensure consistent protection. Verify backup logs and run occasional test restores to confirm integrity.

Maintain an Incident Recovery Plan

Document steps to take during an incident—who to contact, how to isolate systems, and how to restore from backups. A clear plan reduces downtime and stress during a breach.

Secure Collaboration Tools

Video conferencing and team collaboration tools are vital, but improper settings can expose meetings or shared content. Configure tools for privacy and teach household members to respect meeting security.

Use Meeting Controls

Require meeting passwords or waiting rooms, limit screen sharing to hosts, and lock meetings when they’re underway to prevent uninvited participants. These settings reduce the chance of interruptions or leaks.

Keep Collaboration Apps Updated

Update conferencing and collaboration apps promptly to get security fixes and feature improvements. Outdated clients may contain vulnerabilities attackers can exploit.

Restrict Recording and File Access

Limit who can record meetings and who can access shared files, and notify participants when recordings occur. Controlling recordings prevents accidental distribution of sensitive information.

Mobile Device Security

Phones and tablets are often used for work and can be gateways to corporate systems. Secure them with the same care you give laptops and desktops.

Use Device PINs and Biometric Locks

Lock devices with strong PINs, patterns, or biometric authentication to stop casual access. Automatic lock after short inactivity helps reduce risk if you step away.

Control App Permissions

Review and limit app permissions, particularly for microphone, camera, contacts, and location access. Many apps request more access than they need, so you should deny unnecessary permissions.

Enable Remote Wipe and Find Features

Set up remote locate and wipe capabilities so you can clear data from a lost or stolen device. This is crucial if the device contains sensitive company information.

Internet of Things (IoT) and Smart Home Devices

Smart devices can be convenient but often lack robust security, and they may provide an entry point to your network. Isolate and secure IoT devices to minimize risk.

Place IoT Devices on a Separate Network

Put IoT devices on your guest or separate VLAN so that a compromise doesn’t let attackers reach work devices. Network segmentation limits lateral movement.

Change Device Default Settings

Change default passwords and disable unnecessary features on IoT devices to reduce their attractiveness to attackers. Manufacturer defaults are commonly targeted in automated attacks.

Regularly Update IoT Firmware

Install firmware updates for smart devices to close vulnerabilities and improve stability. Many device vendors release important security patches with updates.

Physical Security and Workspace Setup

Physical protection of devices and documents is often overlooked but just as important as digital controls. Protect notebooks, prints, and devices from unauthorized access.

Secure Your Workspace

Lock doors or use privacy screens if you share your living space, and store sensitive documents in locked cabinets when not in use. Physical security prevents opportunistic data breaches.

Protect Against Shoulder Surfing

Be aware of onlookers when working in public or shared spaces, and use screen filters when necessary to reduce readability from an angle. Visual privacy is especially important when entering passwords or viewing sensitive material.

Securely Dispose of Old Devices and Documents

Wipe storage devices before disposal and shred paper documents that contain personal or work-related information. Proper disposal prevents data recovery by unauthorized parties.

Printing, Scanning, and Peripheral Security

Peripherals like printers and scanners often contain memory or network interfaces that can expose data. Manage their settings and physical access.

Change Printer Defaults and Use Secure Printing

Set strong admin credentials on networked printers and enable secure printing features that require authentication to release print jobs. This helps prevent sensitive documents from being printed and left unattended.

Keep Peripheral Firmware Updated

Update firmware on printers, scanners, and NAS devices to patch vulnerabilities. These devices aren’t immune to attacks and often get overlooked.

Use Wired Connections Where Practical

When possible, use wired connections for high-volume or sensitive printing to reduce interception risk over Wi‑Fi. Wired connections can also be more stable and faster for large file transfers.

Monitoring, Logging, and Alerts

Keeping an eye on account activity and device alerts helps you catch issues early and respond before they escalate. Configure alerts and review logs on a regular cadence.

Enable Account Activity Notifications

Turn on alerts for sign-ins from new locations, device additions, and unusual activity for your primary accounts. These notifications give you an early warning about compromise.

Keep Local and Cloud Logs

Where available, enable and retain logs for device and account activity, and review them periodically for anomalies. Logs are essential for post-incident investigation and prevention.

Use Centralized Monitoring Tools if Possible

If your employer provides device management or monitoring tools, enable them to simplify detection and remediation. Centralized tools can automatically enforce policies and provide faster responses.

Housemate and Family Security Awareness

Your household members can unintentionally create security gaps, so teaching them basic practices helps protect everyone. Simple rules and shared responsibilities reduce shared risk.

Share Simple Rules

Ask family members not to plug unknown USB sticks into work devices, not to join work meetings uninvited, and not to install software without permission. Clear rules prevent accidental security lapses.

Schedule Work and Home Device Boundaries

Define which devices are for work and which are for personal use, and avoid mixing sensitive work with casual browsing or gaming. Separate use makes security management simpler.

Offer Basic Training

Provide easy-to-follow guidance about phishing, password hygiene, and safe browsing to household members who may access your home network. A little knowledge goes a long way in preventing incidents.

Incident Response and Reporting

Knowing what to do when something goes wrong reduces damage and speeds recovery. Put a clear incident response plan in place and practice it occasionally.

Establish an Incident Response Plan

Document contact points (IT support, managers), containment steps (disconnect device, change passwords), and recovery steps (restore from backup). Having a written plan removes guesswork during stressful incidents.

Report Incidents Promptly

Tell your employer or IT helpdesk immediately if you suspect a compromise so they can take organization-level steps. Rapid reporting helps protect other employees and systems.

Keep an Incident Log

Record what happened, what you did, and any follow-up steps to help future response and continuous improvement. Documented lessons learned reduce repeat mistakes.

Compliance and Data Handling

If you handle regulated data, make sure you follow applicable policies and legal requirements when working from home. Compliance often requires specific controls, audits, and record-keeping.

Know Your Data Classification

Understand what data is sensitive and how it must be handled, labeled, and stored according to company policy or law. Classification guides how you protect and share information.

Follow Company Policies

Adhere to corporate rules for data access, device use, and remote connections, and ask for clarification when policies are unclear. Compliance helps you avoid legal and professional consequences.

Keep Audit Trails

Where required, retain records of access and sharing in accordance with compliance rules to prove proper handling. Audit trails can be crucial for investigations and regulatory requests.
