Mobile Security - All You Need to Know

As an integral part of our daily lives, mobile phones have become prime targets for cyberattacks. We store a lot of data on our smartphones, be it personal, financial, or something else. 

As such, mobile security is a very important, yet somewhat underreported topic that focuses on protecting mobile devices, apps, and the sensitive information they store.

But hey - that’s why we’re here! In the next few minutes, we’ll go over what makes mobile security, common threats it faces, best practices, and more.

Key aspects of mobile security

There are multiple ways to secure your mobile devices. In an ideal world, you’d employ all of them. But since it’s far from ideal, some combination of the following will have to suffice

1. Device security

A bit of an umbrella term, device security involves protecting the mobile device itself from unauthorized access or theft by any means possible (short of physical violence). This includes the use of strong passwords, biometric methods like fingerprint or facial recognition, and encryption to protect stored data.Encryption is particularly noteworthy since it scrambles the data, making it unreadable to unauthorized users even if they gain access to your device. Full-disk encryption ensures that confidential information remains secure in case the device is lost or stolen.

2. App security

This aspect makes certain that apps of any kind don’t serve as an entry point for malware or data theft. Downloading apps from official stores (Google Play, App Store) minimizes the risk of installing malicious software.Developers regularly release updates to patch security vulnerabilities, so it’s vital to keep track of and install them. Additionally, mobile apps often request permissions to access specific data or system functions, so you should review and limit unnecessary authorizations - every bit helps.

3. Network security

Mobile devices connect to Wi-Fi networks all the time, which includes public and unsecured ones. Unfortunately, this can expose your device to attacks since these networks pose a significant risk because attackers can intercept data transmissions.That’s not to say you’re helpless. For instance, using trustworthy VPNs can keep connections encrypted, thus safeguarding data from being cut off and redirected. Additionally, enabling HTTPS connections (SSL/TLS encryption) for websites provides an extra layer of protection when browsing or accessing cloud-based services.

4. Data security

As the name suggests, data security refers to protecting personal and sensitive information stored on mobile devices. This includes using encryption to safeguard data and DLP (Data Loss Prevention) solutions to stop unauthorized access or transfer of particular details. DLP tools monitor data usage, detect leaks, and ensure that private information like passwords and personal details are secure from external threats. In the event of loss or theft (fingers crossed it doesn’t come to that), regular backups are an essential tool to recover data.

5. Operating system updates

Updating the mobile OS is of utmost importance as it eliminates security vulnerabilities that hackers tend to exploit. Frequent operating system updates maintain the device's security by applying the latest patches and fixes. The good news is that Android and iOS, along with device manufacturers, periodically release updates that address bugs, improve performance, and provide security enhancements. Hence, you should enable automatic updates or manually check for them to stay protected.

6. Mobile device management (MDM)

MDM allows enterprises to control employee mobile devices used for business. It maintains consistent security policies and allows remote tracking of device activity, which is a huge boon considering more and more people opt to work from home.MDM can also be used to remotely wipe data from devices if they are lost or compromised, reducing the risk of privileged company information falling into the wrong hands. In addition, it helps with compliance and legal security requirements..

Common threats and best practices

As you can see, there are several things influencing mobile security, so you must be aware and constantly vigilant to combat any intrusions, be it personal or for your business. Here’s what you should look out for:

• Phishing - attackers send deceptive emails, texts, or social media messages designed to trick users into providing personal information like passwords or credit card details. Mobile users are more vulnerable due to smaller screens, which can hide key phishing signs like suspicious URLs.
• Malware - harmful software can be inadvertently downloaded through apps, attachments, or links. Once installed, malware can steal data, track users, or even control the device remotely.
• Rogue apps - fake or malicious apps disguised as legitimate software are often found outside official app stores. These can gain unauthorized access to confidential data or install hidden malware on the device.
• Unsecured Wi-Fi - public Wi-Fi networks, such as those in cafes or airports, are not encrypted, thus allowing attackers to intercept data. They can use man-in-the-middle attacks (a type of cyberattack where an attacker intercepts communications between two parties) to steal sensitive information like login credentials or banking details.
• SIM swapping - attackers trick mobile carriers into transferring a user’s phone number to a new SIM card, giving them access to accounts linked to the phone number (think verification codes).

To mitigate the above and general mobile security risks, you should:

• Use strong passwords and biometrics - a complex password combined with biometric features (fingerprint, face recognition) provides a tough-to-penetrate layer of security, making unauthorized access extremely difficult.
• Enable two-factor authentication (2FA) - by requiring a second form of identification, such as a code sent to the phone or a biometric confirmation, 2FA significantly strengthens the security of online accounts. However, in the case of SIM swapping, authentication apps offer the most secure method for accessing authentication codes compared to email or text-based codes.
• Limit app permissions - make it a habit to regularly check which permissions are granted to installed apps. Disable access to private information like location or contacts unless absolutely necessary.
• Install mobile security apps - tools like antivirus apps and security suites help a great deal by scanning for malware in real time and taking necessary actions to protect the device from potential threats.
• Keep software updated - both mobile operating systems and apps release frequent updates that patch security gaps. Keeping everything up to date will guarantee you have the latest defenses in place.
• Avoid jailbreaking or rooting - resist the urge as this removes built-in security protections, making the device more susceptible to malware and cyberattacks. It also invalidates warranties and support from app developers.
• Perform data backups every so often - keep critical data backed up to the cloud or an encrypted storage solution. When it comes to data corruption, device theft, or ransomware, having backups ensures recovery without permanent data loss.
• Be cautious when using public Wi-Fi - use a trustworthy virtual private network to encrypt connections when using public networks. This makes data transmission secure and protects it from potential interception by hackers.

Whatever you do, be diligent

A tiny mistake is all that’s needed for attackers to take advantage of a potential exploit. That’s why implementing and sticking to robust mobile security practices is crucial in today’s landscape, where mobile devices are central to both personal and business activities.

By understanding and addressing potential threats, regularly updating software, and using advanced security solutions, you can effectively protect your mobile devices and sensitive data from cyber threats, or at the very least, reduce the risk tremendously.
