Digital Security: The Importance of Protecting Your Online Life

Nowadays, where our lives are increasingly interconnected, protecting personal data has become a fundamental necessity. Every day, we perform multiple online activities that can expose our sensitive information to risks. Concerns about data security are not unfounded; cyberthreats are constantly evolving, and malicious actors are looking for new ways to exploit vulnerabilities in our digital practices. In this context, protecting our privacy and personal data has become more critical than ever.

Personal information has become a valuable asset that malicious actors seek to obtain in various ways. At Akamai, we have observed multiple forms of attacks on vulnerabilities in applications, social networks, or company websites for criminal purposes. These examples demonstrate how, even unintentionally, we can expose our privacy.

Protecting our information is not only a matter of technology, it also involves adopting a responsible and aware attitude with our online activity.

The Vulnerability of Personal Data

One of the most critical aspects of this vulnerability is the use of social networks. Many people share details of their lives that go beyond basic information such as name and age, including real-time locations, family photos, travel and events. This overexposure can be exploited by scammers and stalkers to create fake profiles, conduct targeted phishing attacks or devise social engineering strategies. These tactics allow criminals to impersonate acquaintances and obtain even more sensitive information.

Passwords: The First Line of Defense

One of the most common mistakes we make is using weak passwords or reusing passwords across multiple accounts. One compromised password can give access to several accounts and applications, exposing a vast amount of personal information, thus allowing hackers to sell the information or directly use it for malicious purposes. The solution is simple but effective: create strong and unique passwords for each account. The use of password managers can simplify this task, allowing us to maintain security without the need to remember multiple complex combinations.

To create strong passwords, it is recommended using a combination of uppercase and lowercase letters, numbers and symbols. Passwords should be at least 12 characters long and avoid using common words or easily deducible personal information, such as birth dates or pet names.

Companies making apps or web applications available for their customers are employing additional methods to avoid fraudulent accesses, such as double-factor authentication or services that provide intelligence to identify legitimate versus false attempts.

The Risk of Phishing

Phishing is one of the most common and effective attack techniques. These attacks are disguised as legitimate communications from banks or other online services, requesting personal information. In 2022 itself, phishing attacks and similar crimes increased by 34% compared to previous years, according to Akamai's "The State of Brand Impersonation" report.

Phishing emails can look authentic, with logos and language similar to the real organizations, making them difficult to identify. To protect ourselves from these types of attacks, the best defense is education and caution. We should never provide personal information to suspicious emails or messages and must always verify the authenticity of requests before responding.

In addition, it is useful to be aware of the typical signs of a phishing attempt, such as grammatical errors, unusual email addresses or links that do not match the sender's official domain. 

Although phishing is highly dependent on end user's behaviors, companies are helping with education and alerts, and implementing additional protections, made available by companies that employ analysis of large volumes of internet traffic to detect and prevent access to fake sites.

Public Wi-Fi Networks

Although convenient, public Wi-Fi networks pose a significant risk to online security. When we connect to these networks, we may allow malicious third parties to intercept sensitive data such as login credentials and credit card numbers. To protect ourselves, it is advisable to avoid conducting sensitive transactions or accessing personal accounts while connected to public Wi-Fi networks. 

Education and Caution

Technology can provide us with advanced tools to protect our information, with services that detect and block fraudulent access attempts. . That protection doesn't eliminate the need for the first line of defense which is always ourselves. Adopting a responsible and alert attitude towards our online activity is essential to protect ourselves from cyber threats. We must be aware of the risks and take proactive measures to protect our information.

Additional Measures 

To reduce the risk of data leakage and protect our personal information in the digital age, it is essential to adopt certain practices:

• Make regular backups: Keeping up-to-date backups of your important data can protect you in the event of data loss due to a cyber attack or technical failure.

• Keep your software up to date: Make sure your operating system, browser and applications are always up to date. Updates often include security patches that fix vulnerabilities.

• Disable geolocation when it is not necessary: Many applications request access to your location. Disable this feature when it is not essential to reduce the risk of exposing your location.

• Review app permissions: Before installing a new app, review the permissions it requests. Some applications may require access to more information than necessary.

• Monitor your accounts: Regularly review bank statements and credit reports for any unusual activity that may indicate identity theft.

• Check sites and applications you are not used to before providing any relevant data, looking for indications that they apply good security practices 

Shared Responsibility 

The protection of personal information does not fall solely on users. Companies have a responsibility to implement robust security measures to protect their customers' data. This includes adopting the appropriate tools and services to detect and prevent cyber attacks, as well as training their employees in security practices.

Governments also play a crucial role in protecting users' privacy. We have been seeing Data Protection initiatives in different countries, aiming at establishing the right posture regarding the protection and the use of personal data. Those initiatives establish regulations and standards that compel companies to protect personal data and provide mechanisms for users to report and obtain redress in the event of privacy violations.

Technology companies, for their part, must develop innovative tools and solutions to combat cyber threats. This includes the enforcement of security policies, leading to the adoption of adequate tools to implement them.
