Using certified app stores for iOS and Android is the first line of defense in preventing malware off mobile devices.
However, spyware can be found in open app stores as well. Although the Apple Store and Google Play are fighting to keep harmful apps out of their stores, administrators can reduce their risk by blocking unexpected mobile downloads.
Corporate mobility management or a unified endpoint management platform should also be used to provide a managed environment that allows administrators to handle the basic security profiles of mobile devices. IT can use these profiles to set up a mobile security agent on a device. IT can also activate integrated improved security tools.
An AI-based preloaded app uses this strategy to prevent harmful activity by identifying questionable behavior. This approach still has a cloud component; the agent downloads new suspicious behaviors to flag on the device occasionally, but most of the work is done locally. The best technique to find zero-day exploits is to use mobile behavioral analysis. This solution relies on crowdsourcing to get and test files, but it is more behavior-based than typical signature file antivirus approaches, which rely on simple penetration testing.
Any files that a user receives or downloads to their device are immediately submitted to the cloud service for testing and comparison to see if they’re malware or security threats. Only if the files have been accepted are they loaded onto the device.
This intermediary solution works well for mobile devices, but it can cause performance lags if the mobile devices are connected to a slow network.
Fortunately, the widespread availability of fast 4G, 5G, and LTE networks mitigates this problem.
This method allows mobile security suppliers to conduct expeditious and extensive procedures on high-powered cloud servers, bypassing the limitations of on-device capabilities. The following sort of mobile security keeps track of how apps, and files on the device behave.
Antivirus using signature files is a traditional strategy. The classic signature file antivirus methodology creates a signature file on the device compared to all apps and documents. However, this does not work correctly on mobile devices. Many firms are now using the hybrid-AI strategy described below.
This form of mobile security software examines the files that users download and install on their phones and tablets.
It works similarly to search engines, where users give samples to better the entire experience.
Although no mobile security product is 100 percent effective, given how much sensitive company data is now available on mobile devices, they are a vital first step.
Security software can uncover the warning indications of malicious intent by analyzing these files and apps in the cloud. When artificial intelligence detects harmful files, it inhibits users from downloading and opening them. The tools enforce these standards through a local app that is constantly updated with the most up-to-date information on file security.
Because it does not necessitate a lot of local processing, this cloud-based analytic strategy is ideal for mobile devices. It takes checking a file type against cloud files with moderately fast connections to be minimal.

Any organization that allows mobile devices access to corporate data should consider mobile device management. When it comes to safeguarding mobile devices, MDM is an IT administrator’s first line of defense. The following are some of the most typical profile and compliance settings:
- Encryption of the device and a PIN code
- Authentication with certificates;
- the setting of email;
- Configuration of Wi-Fi;
- Permissions and constraints on the device;
- Apps that use blocklists and allowlists;
- SSO (single sign-on);
- iOS and Android updates are enforced and automated
- Data loss prevention (DLP) configurations;
- Jailbreak/root detection and remediation; and
- Enterprise wipe and complete reset of devices over the air.
In some circumstances, an MDM platform can manage devices running iOS, Android, Windows, macOS, and even Chrome OS. MDM is a versatile technology that allows administrators to control how devices are secured and supported. Consider looking at Apple Business Manager and Android Enterprise apps for business-only mobile devices. They work with the MDM to give businesses additional control over a device’s security settings, such as sophisticated limitations and settings management, home screen layout, single app mode, multi-user and shared methods, zero-touch enrollments, and more.
Admins can do their best to keep mobile devices secure, but once they leave the workplace, they are vulnerable to various threats. An administrator can’t always predict which network a device will connect to or what risk situations it will encounter. Multifactor authentication (MFA) will increase security by validating that the person logging on is who they say they are. It necessitates using two or more authentication methods, such as PIN or password, SMS verification, or biometric factor authentication. It is not recommended to use SMS-based authentication.
What happens if an employee misplaces a device or quits? Every company should adopt a corporate-owned and bring-your-own-device (BYOD) strategy for dealing with device loss and data wipes.
When a mobile device is suspected of being lost or stolen, the business can take steps to protect data, such as wiping data, resetting the device, or locking it. When it comes to BYOD situations, this type of regulation can be tricky; not everyone loves the concept of giving IT so much control over personal devices. Google and Apple, on the other hand, have recently updated their systems to solve this issue.
Keeping equipment up to date is an arduous effort, but it is critical. For example, in March 2021, Apple released iOS 14.4.2, a significant update that corrected a severe WebKit vulnerability and encouraged all users to install it. Mobile devices are becoming a more common target for malware and other types of assaults, and one of the best ways to combat this is to keep all controlled devices up to current.
