Mobiles have become widely used, allowing users to combine personal and professional activities on a single portable device. However, these also come with significant risks. Organisations are now turning to mobile threat defence (MTD) to protect the smartphones and tablets of their mobile workforce from
cyber threats
that can compromise data. In this article, we will discuss what
MTD
entails, the types of threats faced, and effective defence strategies.
The increasing complexity of threats to mobile devices poses a significant concern. As mobile devices play a crucial role in both personal and professional lives, they have become attractive targets for cybercriminals. Bring Your Own Device (BYOD) policies have further amplified these risks, exposing corporate networks to various mobile-specific threats.
As technology advances and user behaviour changes, new threats emerge. Attackers are quick to exploit vulnerabilities, making it essential to stay ahead of the curve.
Most Common Types of Mobile Device Threats
- Phishing attacks: These deceptive tactics often come in the form of links or attachments in emails, texts, or social media messages, aiming to deceive users into disclosing sensitive information.
- Malware: This malicious software is crafted to harm, disrupt, or illicitly access a device without authorization.
- Ransomware: A specific type of malware that locks users out of their devices or data until a ransom is paid to regain access.
- Unsecured Wi-Fi networks: Utilising public or unsecured Wi-Fi connections can leave mobile devices vulnerable to interception and data theft by unauthorised parties.
- App-based threats: Threats arising from malicious or compromised applications installed on mobile devices, which can exploit both personal and corporate data.
- Jailbreaking or rootkit risks: Altering a device's operating system through jailbreaking or rootkit installation can remove essential security features, heightening its susceptibility to various cyberattacks.
Essential Elements of Mobile Threat Defense
Securing our mobile devices involves a combination of crucial components, collectively known as
Mobile Threat Defense
(MTD). MTD comprises various elements designed to address different facets of
mobile security
effectively.
- Real-time threat detection: One fundamental aspect of MTD is real-time threat detection. MTD continuously monitors devices for any signs of malicious activity, promptly responding to any suspicious behaviour detected. This aspect emphasises the importance of identifying threats as they occur, ensuring swift action to mitigate potential risks.
- Automated response and remediation: Another critical component is automated response and remediation. Upon detecting a threat, MTD tools not only alert users or IT teams but also initiate automated actions to contain and neutralise the threat. This automation is particularly valuable in large organisations where manual responses to every alert are impractical.
- Comprehensive visibility and control: A robust MTD approach should offer organisations comprehensive visibility and control over their mobile devices. This entails having a clear understanding of all activities occurring on mobile devices and the capability to manage them efficiently. This component provides insights into a device's security status, including installed applications and usage patterns. Additionally, MTD should enable organisations to enforce security policies remotely, allowing them to identify and address risks proactively before they escalate into significant threats.
