#1 – Mantenha o sistema operacional dos dispositivos móveis protegidos com as últimas atualizações

Keeping the operating system of your mobile devices up to date is one of the most effective measures for ensuring security on mobile devices and protecting your information.

Here are some reasons and benefits for doing so:

  • Correções de Vulnerabilidades: Fabricantes de dispositivos móveis frequentemente lançam atualizações para corrigir vulnerabilidades que foram descobertas desde o último lançamento. Ao atualizar, você garante que seu dispositivo está protegido contra essas vulnerabilidades conhecidas.
  • Melhorias de segurança em dispositivos móveis: Além de correções de bugs, as atualizações do sistema operacional muitas vezes vêm com melhorias de segurança que tornam seu dispositivo mais resistente a novos tipos de ataques.
  • Compatibilidade com Novos Aplicativos: Aplicativos mais recentes podem exigir versões mais recentes do sistema operacional para funcionar corretamente. Ao manter seu sistema atualizado, você garante que pode usar e aproveitar os aplicativos mais recentes e mais seguros disponíveis.
  • Otimizações de Desempenho: Atualizações frequentemente incluem otimizações que fazem seu dispositivo funcionar mais rápido e de maneira mais eficiente.
  • Proteção Contra Malware: Muitos malwares são projetados para explorar vulnerabilidades em versões mais antigas de sistemas operacionais. Ao atualizar, você reduz o risco de seu dispositivo ser infectado.

#2 – Mobile device security also involves backing up your information

Regularly backing up information stored on mobile devices is one of the most essential practices for ensuring the security of mobile devices.

Data loss prevention happens because mobile devices are subject to physical damage, software failures or even theft. In any of these scenarios, without a proper backup, the stored information could be permanently lost.

In practice, in the event of data loss, having an up-to-date backup allows you to restore your information quickly, minimizing interruptions and ensuring the continuity of your daily activities.

#3 – Busque fontes confiáveis para garantir dispositivos móveis protegidos

Marketplaces validate the APPs available, but they are not infallible. For example, in November 2017 a fake version of WhatsApp was downloaded more than 1 million times.

When it comes to installing applications on mobile devices, it is crucial to ensure that they are downloaded from reliable sources.

Applications from unverified sources can contain malware, which can compromise the security of your device and steal your personal information.

In addition, some malicious applications can disguise themselves as updates to popular applications, but in reality, they are fake versions that can harm your device or steal your data.

#4 – Use a screen lock password

Locking the screen with a password is one of the first lines of security on mobile devices. It serves as an initial barrier against unauthorized access, protecting information, applications and device functions from prying eyes or malicious intent.

In addition, the screen lock password is not only a reactive security measure, but also a proactive one. It discourages access attempts, as potential attackers know they will have to overcome this barrier before accessing anything on the device.

This can be especially useful in situations where the device is lost or forgotten in a public place.

Technology has also evolved to offer various forms of screen locking, from traditional alphanumeric passwords and drawing patterns to biometrics such as fingerprints and facial recognition.

These options offer varying levels of security and convenience, allowing users to choose the method that best suits their needs and lifestyle.

#5 – Watch your screen exposure

A person next to you or over your shoulder could be collecting information in an unauthorized way, with the added aggravation of the victim not even detecting it.

To minimize this risk, you can use a privacy film, for example.

In addition to the screen, today audio messages are exchanged, often “played” on speakerphone.

That way, it’s even easier to get information about who’s in the conversation.

#6 – Manter o antivírus atualizado é essencial para a segurança em dispositivos móveis

Keeping your antivirus up to date is essential for the security of your mobile device. With the advance of technology and the growing sophistication of cybercriminals, new types of malware are developed and released on a regular basis.

Antivirus updates are designed to combat these new threats by adding definitions of new malware to their database and improving detection algorithms.

An outdated antivirus may not recognize the latest threats, making the device vulnerable. On the other hand, an up-to-date antivirus identifies and neutralizes these threats, protecting your information and the functioning of your device.

#7 – Securing mobile devices means paying attention when using public Wi-Fi

Public Wi-Fi networks, such as those found in cafés, airports and squares, are convenient, but often not secure. By connecting to one of these networks, you could be exposing yourself to a number of risks.

Firstly, these networks are often unprotected, which means that anyone can access the data you send or receive while connected. This includes sensitive information such as passwords, bank details and personal messages.

There is also the risk of “Man-in-the-Middle” (MitM). In this type of attack, the criminal places themselves between the user and the connection, intercepting and, in some cases, altering the communication between the two. This can be used to steal information or insert malware into the user’s device.

#8 – Configure notifications properly when the screen is locked

The notifications that appear on the locked screen of a mobile device can be a window into personal and sensitive information.

When applications such as email or social networks display previews of your messages or notifications on the locked screen, this can allow someone, at a glance, to find out more about your activities, appointments, contacts or any other information that may be displayed.

In addition, the information displayed in notifications can be used by malicious people in social engineering attempts or other types of attacks.

When it comes to security on mobile devices, it’s crucial to properly configure notifications on the locked screen, limiting the amount of information displayed or completely disabling previews for sensitive applications.

This ensures that your information remains private and protected, even when the device is locked.

#9 – Be aware of the information stored on mobile devices

Mobile devices have become an extension of our lives, storing a vast amount of personal and professional information.

From photos and messages to work documents and bank details, these devices contain details that, if they fall into the wrong hands, could have devastating consequences.

It’s crucial to be aware of the type of information you keep on your smartphone or tablet. Some information, such as sensitive or confidential data, may not be suitable for storage on a device that can easily be lost or stolen.

Being aware of the information stored on your mobile devices is not just a matter of organization, but a fundamental step in ensuring protected mobile devices.

#10 – Enable the remote lock and wipe feature

The remote lock and wipe feature is an essential tool for mobile device security. It allows users to remotely lock their devices, making them inaccessible to anyone who finds them or tries to use them without permission.

In addition to locking, the remote wipe feature allows users to erase all data from the device, ensuring that sensitive information doesn’t fall into the wrong hands. This is crucial because, in many cases, the information contained on the device can be more valuable than the device itself.

In extreme scenarios, it may be more beneficial for the user to ensure that their data is completely erased, even if this means losing access to the device, than to risk exposing this data to malicious entities.
