Precautions when taking your company PC home: Common mistakes and basic rules to prevent trouble

With more opportunities to work while out and about or at home, taking company laptops home has become a common occurrence.

“I want to finish tomorrow's presentation at home,”
“I just need to check an urgent email,”
“I'm using my company PC because I'm working remotely.”

These are situations found in any company, but “taking a PC home” is actually a common entry point for information leaks. A little carelessness can lead to unexpected trouble, so it is important to understand the minimum set of rules.

Common mistakes that occur with take-home PCs

First, let's organize the mistakes that often occur with take-home PCs.

1. Connecting to home Wi-Fi without verifying its security

If your home Wi-Fi encryption method or router settings are outdated, the risk of unauthorized access increases. Avoid connecting without first verifying its security.

2. Moving data using a personal USB flash drive

This is a typical pattern that easily leads to loss, virus infection, and data leaks. Recently, more companies are prohibiting the use of personal USB drives.

3. Opening work screens in front of family members (shoulder surfing)

Even at home, there is a possibility that family members could see screens or documents containing sales materials, customer information, or internal company data.

4. Leaving the PC in the living room while going out

Leaving a PC unattended increases the risk of information leaks due to theft or unauthorized operation.
Screen locks alone cannot prevent the theft of the PC itself.

5. Working while saving files directly to the desktop

If you save files only to the desktop, you risk losing data if the PC is lost or malfunctions. Furthermore, the company cannot monitor the status of those files.

Basic rules for safe use at home

Next, let's review the basic rules for safe use at home.

1️⃣ Protect your home Wi-Fi with WPA2 or WPA3

Avoid older encryption methods like WEP, and set a Wi-Fi password that is difficult to guess.

2️⃣ Do not use personal USB flash drives (make this a prohibited rule)

Use company-designated services like Google Drive, OneDrive, or SharePoint to exchange data.

3️⃣ Save to the cloud, not the desktop

Do not save files only to the desktop; use company-designated storage locations such as OneDrive or Google Drive. This makes it easier for the company to check and recover data if the PC is lost or malfunctions.

4️⃣ Do not let family members use the company PC

Do not open sensitive information in front of family members, and lock the screen when leaving your seat.
If you must work in the living room, a privacy screen filter is effective.

5️⃣ Be careful of physical theft while out and about

• Never leave the PC in a car

• Always carry it with you when leaving your seat

• Do not leave your bag unattended in luggage storage areas

The theft of the PC itself cannot be prevented by settings alone.
To minimize information leakage in the event of theft, the company should also configure screen locks and storage encryption.

Minimum rules the company should establish

Leaving it up to employees leads to inconsistent practices and becomes a breeding ground for trouble.
The following are the minimum items the company should establish.

• Rules for taking PCs home

• Conditions for home Wi-Fi

• Standardizing data storage locations to company-designated areas

• Prohibition of personal USB use

• Clearly defined contact procedures in case of loss

There is no need to create detailed regulations from the start.
Even just summarizing the 'things you must not do' on a single sheet can reduce the risk of accidents.

Make take-home PCs secure through 'systems'

In today's work environment, there are times when it is necessary to take your work PC home.
However, if you use it with the same mindset as in the past, information leaks can occur in unexpected places.

What is important is not to rely on the attentiveness of employees, but to create a "company-wide system."

A few rules and unified operations will be a great force in protecting the company's credibility.
