The 10-Step Checklist for Securing Samsung Devices Before Handing Them to Employees (Printable SOP)

In today's booming enterprise mobility landscape, Samsung devices have become the preferred choice for businesses worldwide due to their powerful hardware performance and defense-grade security architecture, Samsung Knox.

However, security risks often peak during the "last mile" of IT departments delivering new devices to employees. Without a standardized Samsung device security checklist, employees may exploit system vulnerabilities or default settings to install non-office applications, enable risky debug modes, or even erase company ownership by restoring factory settings after the device is lost.

Ensuring secure Samsung phones before handing them to employees is not only a technical compliance requirement but also the first line of defense against corporate data breaches.

Traditional Mobile Device Management (MDM) often focuses on daily monitoring, but the initial hardening before delivery determines the effectiveness of all subsequent enforcement measures.

This article aims to provide IT professionals with a comprehensive, printable Standard Operating Procedure (SOP) covering the entire process from basic permission acquisition to advanced restriction settings.

By combining leading MDM solutions such as AirDroid Business, administrators can implement batch, mandatory security baseline deployments to ensure that every Samsung device distributed is a "secure out of the box" office terminal.

Part 1: Prerequisites Before You Start

Before implementing any specific hardening steps, understanding Android's management architecture is a prerequisite for ensuring policy effectiveness.

Many administrators find that policies fail to execute after configuring MDM, usually because devices are not registered in the correct mode. To achieve the highest level of security control, enterprises must ensure that Samsung devices have "irrevocable" administrative permissions at the system level.

1Recommended Enrollment for Strong Enforcement (Device Owner)

To meet the stringent requirements of the Samsung MDM policy checklist, it is recommended that all enterprise-owned Samsung devices be registered using Device Owner (also known as Fully Managed Mode).

In this mode, MDM applications (such as the AirDroid Biz Daemon) are granted the highest system management privileges, enabling the following key capabilities:

Silent installation and uninstallation: Distribute business applications without user confirmation.

Prevent factory resets: Block users from evading management at the system level.

Forced policy enforcement: Restrictions remain effective even if the user enters safe mode.

In contrast, the Profile Owner mode commonly used for BYOD (Bring Your Own Device) only controls applications within a work profile and cannot lock the hardware interfaces of the entire device (such as USB debugging or mobile hotspot), therefore it is not suitable for delivery scenarios with high security requirements.

2Preflight Checklist (5-minute setup check)

Before proceeding with the formal 10-step hardening process, IT administrators should complete the following preparatory work:

Part 2: The 10-Step Samsung Device Security Checklist (Printable SOP)

This section is the core of the entire document, detailing the hardening steps for Samsung devices before delivery. Each step is broken down according to four dimensions: "Importance Description, Parameter Settings, Configuration Path, and On-site Verification".

1Step 1 — Enforce a Strong Screen Lock Password Policy

Why it's important: Screen lock is the first line of defense for physical security. When an employee's device is lost or stolen due to negligence, without the constraints of a password policy like Samsung MDM, attackers can easily access locally stored emails, customer data, and internal system tokens.

A strong password policy significantly increases the cost of brute-force attacks and, combined with encryption technology, protects data at rest.

Strengthening parameters:

Password complexity: Requires the inclusion of letters, numbers, and special characters (alphanumeric).

Minimum length: Set to at least 8 characters (a balance between usability and security is recommended).

Maximum number of failed attempts: Set to 10. After exceeding this number, the device should automatically trigger local data erasure to prevent physical penetration.

Validity period: Mandate changing passwords every 90 days to prevent the leakage of long-used passwords.

AirDroid Business configuration path: Log in to Admin Console > Policy & Kiosk > Policy > Password > Enable Passwords Meet Complexity Requirements and configure specific rules.

2Step 2 — Enable Device Storage Encryption

Why it's important: While modern Samsung devices are typically encrypted by default, explicitly enabling encryption on Samsung work phones via MDM is crucial for ensuring compliance.

If device storage is not encrypted, attackers can directly read binary data by removing flash memory chips or exploiting underlying vulnerabilities. Enforcing encryption ensures that all data at rest is completely unreadable without the correct decryption key.

Reinforcement parameters:

Forced status: Enable forced encryption.

Knox integration: For highly sensitive roles, it is recommended to combine this with Samsung Knox's DualDAR technology, providing an extra layer of protection for data even when the device is powered on and locked.

AirDroid Business configuration path: Policy > Restrictions > Device Functions > Check Force storage encryption.

On-site verification: Search for "Security" or "Encryption" in the device's "Settings". The verification status should show "Encrypted" or "Encryption enforced by administrator". Try connecting to a PC without unlocking the screen to verify that no internal storage files can be accessed.

3Step 3 — Disable Developer Options

Why it's important: Developer options provide advanced users with access to debug the system, which is extremely risky in an office setting. Employees could use developer options to manually modify location information (simulate GPS), enable insecure services, or bypass specific restrictions of MDM.

Therefore, disabling developer options in Samsung MDM is a baseline requirement before handing it over to non-technical employees.

Strengthening parameters:

Completely disable: Prevent users from accessing this menu.

Hide trigger: Disable the regular activation mechanism of "tapping the build number 7 times" through MDM policies.

AirDroid Business configuration path: Policy > Restrictions > Safety > Find Developer mode and switch it to "Off".

Field verification: Go to device "Settings" > "About phone". Tap the "Build number" repeatedly. If the policy is effective, the system should display "This operation has been restricted by the administrator", and the developer options menu will not appear in the settings list.

4Step 4 — Disable USB Debugging (ADB)

Why it's important: USB debugging (Android Debug Bridge, ADB) allows an external PC to communicate with the phone via a command-line interface. This is the most common channel for malware to extract application data, install malicious APKs, or forcibly reset devices.

Blocking the ADB channel is crucial in preventing targeted physical attacks during the process of securing Samsung phones before handing them to employees.

Strengthening parameters:

Independent Disabling: Even if developer options are enabled (e.g., through vulnerabilities), the USB debugging switch should always remain locked.

AirDroid Business Configuration Path: Policy > Restrictions > Safety > Find USB debugging and disable it.

Field Verification: Connect the device to a PC with the ADB driver installed. Run the `adb devices` command. If the device is not listed or displays "Unauthorized," the reinforcement was successful.

5Step 5 — Block Factory Reset from Settings (Stop Unenrollment Attempts)

Once an employee restores a device to factory settings, all MDM policies and enterprise data are erased, leaving the device uncontrolled.

Blocking factory resets with Samsung MDM ensures the device remains under control throughout its balance sheet lifecycle.

Combined with Samsung Knox's FRP (Factory Reset Protection), it ensures that even if a user forcibly resets the device via hardware key combinations, it cannot be activated without an enterprise account.

Strengthening parameters:

Hide option: Gray out or completely remove the "Reset" button in the settings menu.

Enable FRP: Configure a specific Google account for re-authentication after a reset.

AirDroid Business configuration path: Policy > Restrictions > Safety > Enable Factory reset restrictions.

On-site verification: Go to "General Management" > "Reset". Check the "Factory Reset" option. It should be grayed out and unclickable, or a "Administrator does not allow this operation" notification should pop up when clicked.

6Step 6 — Block Unknown Sources APK Installs (Stop Sideloading)

Why it's important: The vast majority of Android malware and Shadow IT apps are "sideloaded" through third-party download sites or APK files.

Preventing unknown sources APK installation on Samsung devices forces employees to download only approved apps from official app stores or the company's private App Library, significantly reducing the risk of virus infection and data breaches.¹⁹

Strengthening parameters:

System-level blocking: Globally disable the `install_unknown_sources` permission.

App library whitelist: Ensures that APKs distributed by the IT department are not subject to this restriction, maintaining business continuity.

AirDroid Business configuration path: Policy > Restrictions > Apps > Set Allow unknown sources to "Off".

Field verification: Download a test APK in a mobile browser. When you click install, the system should prompt "For security reasons, your phone does not allow the installation of unknown apps from this source," and this switch cannot be manually enabled in the settings.

7Step 7 — Prevent Users from Uninstalling Required Business Apps

Why it matters: In industries like logistics, retail, and healthcare, specific business apps (such as POS, inventory management, and electronic medical records) are core functionalities of devices. If employees accidentally delete or maliciously uninstall these apps, it can lead to productivity stagnation and costly on-site support. With Samsung MDM's "Prevent Uninstall Business Apps" feature, administrators can ensure 100% uptime for these critical tools.

Strengthening Parameters: App Lock: Enable the "Prevent Uninstall" attribute for business apps marked "Required" or pushed to the device.

AirDroid Business Configuration Path: Policy > Restrictions > Apps > Disable Uninstall app option.

On-site Verification: Long-press the business app icon on the home screen. If the policy is effective, the "Uninstall" option will disappear, or the button will be grayed out when attempting to uninstall from the app details page in settings.

8Step 8 — Disable USB File Transfer (Data Exfiltration Control)

Why it's important: Even with debugging mode disabled, standard USB MTP (Media Transfer Protocol) still allows users to directly copy photos and documents from their phone to their PC.

This is absolutely prohibited in jobs handling highly sensitive data (such as research drawings or patient information). Disabling USB file transfer allows Samsung to physically prevent unauthorized data export.

Strengthening parameters: Charging-only mode: Forces the default USB behavior to charging only, not responding to any data requests.

Disable external storage: Simultaneously disables USB OTG (external flash drive mounting).

AirDroid Business configuration path: Policy > Restrictions > Sync & Transfer > Disable USB file transfer and USB external device.

Field verification: Connect the device to the computer. Check the USB option in the notification bar on the phone. It should be locked to "Charging only" and cannot be switched to "File transfer". The phone's drive letter should not appear in the computer's file explorer.

9Step 9 — Restrict Account Changes (Reduce Shadow IT)

Why it matters: Allowing employees to add personal Google, Facebook, or personal email accounts to their work devices introduces shadow IT. Personal accounts can be used to sync company contacts or automatically upload photos to personal cloud storage, creating compliance loopholes.

By blocking the addition of Google accounts to work phones, IT can ensure that all identity credentials stored on the device are under the control of the company.

Strengthening parameters: Lock account management: Prohibit the addition, modification, or deletion of system accounts. Dedicated control of Google accounts: For Android devices, specifically prohibit adding personal Gmail accounts outside the Play Store.

AirDroid Business configuration path: Policy > Restrictions > Users & Accounts > Disable Allow adding/deleting accounts.

On-site verification: Go to Settings > Accounts & Backup > Manage Accounts. Click the "Add Account" button. If the policy is in effect, this button should be disabled or display a message saying "Administrator does not allow this operation."

10Step 10 — Disable Network Sharing (Hotspot/Tethering)

Why it matters: Mobile hotspot sharing bypasses enterprise-level DNS filtering and traffic auditing. Employees could use company traffic to provide internet access for their personal devices, resulting in high data bills. More seriously, malicious hotspots are breeding grounds for man-in-the-middle (MITM) attacks.

Disabling hotspot Samsung MDM ensures devices only connect to secure networks approved by the company.

Hardware Strengthening parameters: Hardware switch lock: Completely disables the switches for mobile hotspot, USB tethering, and Bluetooth tethering.

Data quotas: As a supplement, monthly data usage thresholds can be set for alerts.

AirDroid Business configuration path: Policy > Restrictions > Sharing > Turn off Network sharing option.

Field verification: Try clicking the "Mobile Hotspot" icon from the quick settings (drop-down menu). The icon should turn gray or disappear completely. In system settings, the feature should display "Disabled by administrator."

Part 3: Verification & Handover (5-Minute QA Routine)

Before handing ruggedized Samsung devices to employees, conducting a standardized quality assurance (QA) test is essential to mitigate future risks. This is not only a technical verification but also the construction of a chain of evidence for compliance.

1Quick QA Tests (Must-pass)

Administrators should perform a quick manual test on the following items within one minute:

2Document the Handover (Audit Trail)

To ensure traceability of asset management, it is recommended to complete the following form upon delivery and keep it as a delivery record:

Part 4: Optional Hardening Add-Ons (Use Case Dependent)

Depending on the specific business needs (Use Case), administrators can also choose to apply the following advanced strategies to further reduce the risk area 1.

1Disable Camera / Microphone (Regulated environments)

In research and development centers, medical operating rooms, or regulated financial institutions, physical privacy is the highest priority. Administrators can completely disable a device's audio and video recording capabilities.

Configuration: Policy > Restrictions > Device Functions > Turn off Camera and Microphone.

Result: All apps that access the camera (including the native camera) will display a "Restricted Permissions" message or fail to launch.

2Apply Android Kiosk Mode for Dedicated Devices

If the Samsung device is used as a retail POS machine, electronic billing system, or queue management system, single-app locking is best practice.

Configuration: Enter Kiosk settings (separate from the regular policy). Select Single-app mode and specify the core business app.

Effect: Employees cannot exit the current app, view the notification center, or even adjust unauthorized settings. This significantly reduces the rate of accidental operations.

3Enable Do Not Disturb governance (if applicable)

Samsung provides the OEMConfig protocol, allowing MDMs like AirDroid to access Samsung-specific hardware features not natively supported by Android.

Advanced capabilities include: locking always-on VPNs, configuring specific Samsung physical buttons (such as the XCover button), and forcibly enabling mobile data firewalls.

Part 5: Troubleshooting (When a Step Doesn’t Take Effect)

If you find that a policy is not working when executing the Samsung MDM policy checklist, please focus on checking the following three aspects:

1Check Enrollment Mode (Device Owner requirements)

Most stringent restrictions (such as disabling reset and preventing uninstallation) only apply in Device Owner (DO) mode. If the device was added after activation via a normal download and installation, it will only have standard Profile Owner privileges, rendering core security policies ineffective.

Solution: A factory reset must be performed first, followed by re-registering by clicking the welcome screen six times and scanning the QR code.

2Check Android OS Version Limitations

Some policies have minimum system version requirements (for example, forced storage encryption typically requires Android 6.0+, and some account restrictions require Android 7.0+).

Solution: Check the OS version in the device list in the AirDroid console. If the version is too low, it is recommended to push a system update first.

3Check Agent/Permissions Status

The MDM backend must maintain a heartbeat connection with the device. Policy delivery may be suspended if the device is in "Power Saving Mode" or in an environment with no network access.

Solution: Check the device status in the console. If it displays "Offline," ensure the device is connected to the internet. Manually open the AirDroid Biz Daemon on the device and check if all permissions are displayed in green.
