Want to strengthen your phone’s security? Let’s take a closer look at proven methods that work.

Smartphone Security Basics

“Cybercrime is the greatest threat to every company in the world.” — Ginni Rometty, Former Chairman, President and CEO of IBM

Cybercriminals target smartphones more than ever, and mobile security threats continue to grow rapidly. Research shows a substantial 17% increase in enterprise-focused credential theft and phishing attempts in 2024 ^[1]. Mobile malicious app detections jumped by 32.4% in a single quarter ^[1].

Why your phone needs protection

Your smartphone holds vast amounts of sensitive information. Banking details and work emails make these devices a rich source of personal and professional data. Recent data shows mobile banking continues to expand, with 86 live mobile money services operating in Southeast Asia alone ^[2].

Mobile devices face unique security challenges because they:

• Stay powered on and connected
• Connect to unsecured networks regularly
• Can be stolen easily
• Lack proper security measures

Recent data shows mobile phones link directly to business email compromise (BEC), MFA bypass attacks, and executive impersonation ^[1]. Research also indicates iOS devices face higher exposure to phishing and web content threats compared to Android devices ^[1].

Common security threats in 2024

The mobile threat landscape has changed dramatically and created several key security challenges:

Sophisticated Phishing Attacks: Small screens and live email monitoring make mobile users vulnerable to phishing attacks ^[3]. WhatsApp accounts for 82.71% of mobile phishing attempts, while Telegram follows with 14.12% ^[2].

Malicious Applications: Third-party app stores create significant risks because they lack proper security checks ^[4]. These stores often distribute free versions of paid apps that contain malware designed to steal user data.

Network-Based Threats: Criminals set up fake access points in busy public spaces using names like “Free Airport Wi-Fi” to trap users ^[3]. These fake networks can steal sensitive data, including login details and financial information.

Data Leakage: “Riskware” apps request too many permissions and send personal data to remote servers where advertisers or criminals can access it ^[3]. Mobile ransomware has also increased, with researchers finding 10,543 mobile ransomware Trojan installers worldwide ^[2].

Spyware and Surveillance: Spyware installed by spouses, coworkers, or employers has become common ^[3]. These apps can track locations, steal data, and access device cameras without users knowing.

Security incidents have damaged user trust, with 73% of users reporting less confidence in their smartphone brand and operating system developer ^[5]. The situation looks even worse in Asia Pacific, where one in four internet users has experienced identity fraud ^[2].

Set Up Essential Security Features

Your smartphone’s security features are your first defense against unauthorized access and data theft. Let’s look at some significant security measures that will protect your device.

Create strong unlock methods

A secure unlock method stops unauthorized physical access to your device. PINs are still popular, but they need to be unique and avoid obvious combinations. Simple patterns like “1111” won’t cut it – you need complex PINs with random numbers ^[6].

Here are some better unlock options to think about:

• Pattern Lock: This works better since it’s harder to link with personal details
• Password: The highest security comes from mixing letters, numbers, and symbols
• Fingerprint: A good balance of convenience and protection, though you’ll need backup authentication after 48 hours ^[6]

Enable find my phone

Your lost or stolen device can be located, locked, or erased remotely with the “Find My Device” feature. Start by checking your email address in device settings. Then turn on Location Services and “Find My Device” in your Google account settings ^[7].

This feature gives you three vital functions:

• Play Sound: Helps you find devices nearby
• Lost Mode: Locks and tracks your phone’s location
• Remote Erase: Wipes your personal data if you can’t get the phone back

Android users can also turn on offline finding. This feature stores encrypted recent locations with Google and helps find devices through other Android devices in the network ^[7].

Configure auto-backup

Your valuable data stays safe with regular backups if your device fails. Android’s Auto Backup feature saves up to 25MB of app data per user in your Google Drive without using your storage quota ^[8].

Auto backup starts when:

• Backup is on in device settings
• A day has passed since the last backup
• The device isn’t being used
• It’s connected to Wi-Fi (unless you allow mobile data backup) ^[9]

Your backups stay secure with encryption using your Google Account password ^[9]. Devices running Android 9 or higher get extra encryption using your device’s screen lock credentials ^[8].

Here’s how to set up automatic backups:

1. Open Settings and select Google
2. Tap Backup
3. Enable “Back up to Google Drive”
4. Pick what to backup (Photos, videos, device data)
5. Tap “Back up now” to start your first backup ^[9]

Both devices must run compatible Android versions to restore data. You can’t restore data from a newer Android version to an older one ^[9]. Keep your device updated with the latest security patches and operating system updates.

Protect Your Phone Data

Smartphone data protection needs more than simple security features. Mobile threats keep evolving, and strong data protection measures must safeguard your personal information.

Secure your apps and accounts

You should verify an app’s legitimacy before downloading it. Look at user reviews, check if the app store is genuine, and match the developer’s official website with the app store link ^[10]. Android users face fewer risks of malware-infected applications by staying within the Google Play Store ^[11].

To boost app security:

• Get security apps that track location remotely
• Add remote data wiping options
• Turn on automatic security updates
• Set up two-factor authentication for sensitive apps

Manage app permissions effectively

Apps ask for access to sensitive information often. Giving unnecessary permissions makes your data more vulnerable to breaches. A newer study, published in many apps collect and sell large databases of user information to third parties ^[12].

Your app permissions need careful management:

1. Check current app privileges in your device’s privacy dashboard
2. Stop unnecessary access to sensitive features like camera, microphone, and location
3. Let apps use location “Only While in Use” if they need it
4. Delete unused apps that might still have access permissions

Android’s strong permission system lets you block apps from seeing specific parts of your digital life ^[13]. Most modern apps work fine with limited permissions ^[13].

Enable data encryption

Device encryption remains one of the most powerful tools to protect your smartphone data. This security measure keeps your files and folders safe from unauthorized users if you lose your device or someone steals it ^[14].

The encryption process works best when you:

Your device needs a full charge and power connection since encryption takes time ^[14]. Create a strong lock screen password or PIN and never use default settings or share these credentials ^[4].

Mobile device encryption ‘scrambles’ all protected data. This makes the information useless to anyone without proper authentication ^[2]. The process protects not just your device but your entire digital ecosystem from data breaches ^[2].

Android’s lock screen and device encryption work as a team – encryption needs screen lock first ^[15]. iOS devices include built-in data protection that automatically encrypts personal data, texts, emails, and app data once you set up a passcode ^[15].

Note that encrypting your Android smartphone means you’ll need a factory reset to undo it ^[15]. Professionals in finance and healthcare must encrypt their devices – it’s not a choice but a legal requirement ^[15].

Safe Phone Usage Habits

“Amateurs hack systems, professionals hack people.” — Bruce Schneier, American cryptographer, computer security professional, and writer

Public WiFi networks are a huge risk to your smartphone security. A recent survey showed that 70% of tablet owners and 53% of smartphone users keep connecting to public WiFi hotspots ^[16]. These networks might be convenient but they lack simple security measures, which makes them attractive to cybercriminals.

Public WiFi safety tips

You can protect your data on public WiFi by following these safety measures:

Make sure the network is genuine. Cybercriminals often set up fake networks that look like legitimate businesses ^[1]. The quickest way to stay safe is to ask staff members about the official network name and IP address before connecting.

Your devices might connect to nearby networks automatically, which could lead to unsafe connections ^[1]. Turn off automatic network connections and file sharing features. If you leave file sharing on, anyone on the same network could access your folders ^[17].

Here’s how to tap into the full potential of public WiFi security:

• Use a Virtual Private Network (VPN) to encrypt your data
• Enable private browsing mode
• Stay away from sensitive accounts
• Remove unused WiFi networks from your device
• Switch off Bluetooth in places you don’t know ^[16]

Secure mobile payments

Mobile payments just need strict protection measures. The data shows that cyberattacks targeting payment systems increased by 31% between 2020 and 2021 ^[5].

Here’s how to protect your mobile payments:

Get your payment apps from trusted sources only. Official stores are the best place to download apps, and you should update them regularly to fix security issues ^[18]. Set your device to lock automatically when idle and require authentication for payments.

Strong authentication methods are crucial. PINs might be convenient, but passwords give you better protection against unauthorized access ^[19]. The best protection comes from using biometric authentication along with traditional security measures.

Your device needs secure communication with payment servers. Look for “HTTPS” in payment website URLs – this suggests an encrypted connection ^[17]. On top of that, it’s risky to make payments over public WiFi networks since others can easily intercept these transactions ^[20].

Report anything suspicious right away. If you see unauthorized transactions or lose your device, contact your payment service provider immediately ^[18]. Quick reporting helps prevent money loss and keeps your personal information safe.

Business transactions need these extra safeguards:

• Install mobile-specific anti-malware software
• Keep your device firmware current
• Set up payment app timeouts
• Create different passwords for each payment service ^[18]

Note that you should watch for signs that someone has compromised your device. Unusual pop-ups, frequent disconnections, or unexpected performance issues might mean your payment security is at risk ^[21]. These signs call for immediate action to protect your financial data.

Respond to Security Threats

Quick action against smartphone security breaches can save your personal data from extensive damage. You need to know the warning signs and act fast to protect your digital world.

Signs your phone is compromised

Your device might show several red flags when security is at risk. A sudden increase in data usage without any changes in your online habits could mean malicious apps are running quietly ^[3]. Your phone’s battery might drain faster than usual and feel hot to touch, which often points to unauthorized processes running behind the scenes ^[22].

Watch out for these warning signs:

• Apps you never installed showing up
• Two-factor authentication codes you didn’t ask for
• Strange changes in camera or microphone permissions
• Random pop-up ads appearing ^[22]

Steps to take if hacked

The moment you find a security breach, take these steps right away:

Cut off your device’s internet connection and turn off remote access features ^[23]. This stops hackers from stealing more data and limits their control over your device.

Run a scan with trusted anti-malware software ^[24]. Get rid of any suspicious apps and check if your remaining apps are legitimate through official sources ^[22].

Your passwords need immediate updates for all linked accounts. Start with your banking and email accounts ^[22]. Adding two-factor authentication gives you extra security ^[24].

How to report security incidents

Security breaches need proper reporting to authorities. This helps them break down the case and stop future attacks. Your local police should hear about it first – they work better when you tell them quickly ^[3].

Here’s where else to get help:

• The FBI’s Internet Crime Complaint Center (IC3) handles cyber-enabled crimes ^[25]
• Your mobile service provider can stop unauthorized activities ^[22]
• Banks need to know if someone accessed your financial information ^[3]

Identity theft victims should file a report at IdentityTheft.gov. The site creates individual-specific recovery plans based on what information leaked ^[3]. Law enforcement agencies tap into this data through the Consumer Sentinel Network to track and investigate cybercrime patterns better.
