Core Capabilities of Mobile Threat Defense
Real-time Threat Detection
Mobile threat defense protects devices from external threats, such as malware, phishing attacks, external USB device threats, etc., in real-time. MTD software constantly monitors devices for signs of malicious activities and immediately responds when something suspicious is detected.
MTD detects threats as they happen and actively seeks potential vulnerabilities before they cause harm. For instance, if a user clicks on a malicious link, the MTD solution will immediately detect the link as a threat and block the download to prevent malware execution. It sends an alert to the user, providing details of the threat and actions taken. Additionally, it scans the device for residual threats, ensuring comprehensive protection and enhancing the organization’s security posture.
Anomaly Detection
A mobile threat defense solution continuously supervises device behavior and usage trends. It can detect deviations from normal patterns that may indicate a security breach. For instance, if a device suddenly begins transferring a large volume of data to an unfamiliar server, this could signal a potential threat.
Modern MTD platforms leverage advanced machine learning algorithms to identify device, user, or application behavior anomalies. By applying heuristics and behavioral analytics, these solutions can detect and stop threats before they take hold. This includes identifying potentially unwanted software applications and suspicious actions performed by or on behalf of the user, such as those initiated by malware.
Data Loss Prevention
An MTD solution safeguards sensitive data from unauthorized access. It implements robust measures such as encryption, access controls, and remote wipe capabilities to ensure data security. It continuously monitors for potential data leaks, particularly those occurring when apps try to access data from other apps, which can be especially problematic when crossing between personal and business-approved apps.
For instance, if a gaming app attempts to access your contact list, the MTD software recognizes this as an unnecessary and risky action and promptly blocks it. By preventing such unauthorized access and potential data leaks, MTD ensures sensitive information remains secure and private, maintaining the integrity and confidentiality of your data.
Threat Intelligence
Threat intelligence empowers MTD solutions to stay ahead of the latest mobile threats and attack vectors. By leveraging threat intelligence feeds and databases, MTD solutions maintain up-to-date knowledge of emerging threats.

How does Mobile Threat Defense Work?
Mobile Threat Defense solutions work meticulously at three essential levels: network, application, and device. Each level offers a distinct set of security features, strengthening the defense against potential mobile threats.
1. Network Level
MTD at the network level ensures a secure connectivity environment, protecting data as it travels from the device to the cloud and across networks. It acts as a security guard, constantly monitoring and safeguarding data in transit.
Monitoring Network Threats: MTD solutions continuously monitor for known threats and suspicious activities that could compromise network security. It scans network traffic, identifies and neutralizes threats before they cause damage, and automates network traffic encryption when connecting to open Wi-Fi. This way, data remains protected from unauthorized access as it travels across networks.
Network Packet Analysis: Mobile Threat Defense solutions scrutinize each network packet for signs of malicious activity or anomalies. This deep dive into network packets allows MTD solutions to detect known threats such as man-in-the-middle (MitM) attacks and Secure Sockets Layer (SSL) stripping.
SSL stripping is a particularly insidious attack where an HTTPS connection is downgraded to an unsecured connection, enabling attackers to collect sensitive data. By monitoring network packets, MTD can identify and thwart such attacks, ensuring data remains protected during transmission.
Automatic Encryption on Open Wi-Fi: Open Wi-Fi networks are vulnerable to cybercriminals. An MTD solution automatically encrypts traffic on these networks, creating a secure tunnel for data transmission. This means that even if employees connect to a coffee shop’s Wi-Fi, MTD ensures their data is scrambled and unreadable to prying eyes, enhancing security in open environments.
2. Application Level
At the application level, MTD creates a secure environment where apps can operate without compromising device security or user privacy. It monitors applications to ensure they function as intended and do not pose any security risks.
Monitoring Application Activity: MTD closely monitors all application activities, particularly looking for anything out of the ordinary. For example, if an app unexpectedly begins to leak data, an MTD solution instantly detects and stops this behavior.
Code Analysis: An MTD solution examines every line of code within applications. It remains vigilant for gray ware, which behaves unethically but not maliciously, and malware, designed to harm devices. Through code analysis and reverse engineering of applications, it ensures apps are free from harmful elements, safeguarding both the device and its data.
Data Leakage Prevention: Data leakage is a significant issue, particularly when apps share data inappropriately. MTD stops this unauthorized data access and sharing among apps. For instance, it ensures personal apps do not share data with business apps, maintaining a strict separation between personal and business data.
Privacy Protection: A Mobile Threat Defense solution monitors apps to prevent activities that could compromise user privacy. MTD prevents applications from accessing sensitive information without authorization, ensuring privacy breaches are mitigated. It detects and prevents privacy issues, ensuring apps respect user privacy and do not engage in compromising activities. With MTD, users can trust that their sensitive information remains secure and protected.
3. Device Level
Unpatched OS monitoring: Devices with unpatched operating systems can be gateways to security vulnerabilities, compatibility issues, and slow system performance. MTD monitors such devices for unpatched operating systems and ensures they are protected against known security vulnerabilities that attackers could exploit.
Checking for Rooted/Jailbroken Devices: MTD scans devices to detect if they have been rooted (Android) or jailbroken (iOS). Rooted or jailbroken devices pose an increased security risk as they bypass built-in security mechanisms. MTD identifies such devices and can take appropriate actions, such as restricting access to corporate resources.
Assessing External USB Device Threat: Though external USB devices are popular for data storage, they can pose a security risk. USB devices can be used to inject malware into devices they connect to, making them potential threats to your device’s security.
