This growing dependence on technology extends beyond our personal activities. It is vital to understand that this reliance also encompasses the critical infrastructures of the country.
With the increasing number of Internet-connected devices, privacy and the protection of our personal data are becoming increasingly vulnerable to threats. Important tasks such as submitting tax returns or checking bank account balances are often carried out online, exposing them to various types of attacks.
This growing dependence on technology extends beyond our personal activities. It is vital to understand that this reliance also encompasses the critical infrastructures of the country. If these infrastructures are compromised, the impact can be significant on national security and people's daily lives, from power outages to interruptions in communication services. Thus, cybersecurity emerges as a comprehensive concern, not only for technology experts but for everyone.
Often, we use the same passwords across various services for ease of memorization. It is crucial to choose strong passwords to protect data. Ideally, use combinations of letters, numbers, and symbols, avoiding personal information. For example, "Xb@s@U3eXD6P6%7" is more secure than "Casa123456". Multifactor authentication is another way to enhance security by adding an extra layer, comparable to having a card and PIN at an ATM.
These practices reinforce online security. Understanding signs of suspicious online activities is crucial. Phishing, for example, is a common tactic where malicious individuals attempt to obtain personal information. When receiving an email requesting data updates, but something seems off, it is crucial to exercise caution. It is recommended to verify the authenticity of such communications before sharing sensitive information. When receiving a request for personal data, one should carefully check the sender, identify any spelling errors, or dubious links. This discernment is vital to protect yourself against online threats and maintain the security of personal information. Keeping software updated is an important step in preventing vulnerabilities.
The operating system, browsers, and applications should always be updated to ensure known security flaws are fixed, and risks are minimized. Additionally, automatic updates should always be enabled. Device protection is a vital component of cybersecurity. Using antivirus software and security tools on devices, such as computers and smartphones, provides an additional barrier against threats.
Activating firewalls helps block potential attacks and strengthens system defense. These practices are important not only for organizations but also for the average user. There are also other practices more geared towards organizations but may also make sense for other contexts. Regularly backing up documents and configurations is one of the most important practices that can prevent irreparable losses in case of ransomware attacks or hardware failures.
It is generally good practice to store copies on external devices (such as hard drives) or use cloud services if the documents do not contain personal data, for example. Cybersecurity training is not only important for large companies. It is useful for all organizations and individuals. Developing disaster recovery plans that include data restoration in severe security situations is of utmost importance. To add an additional layer of security, the importance of data encryption is highlighted.
This practice is similar to putting information in a box with a lock, allowing only the authorized person to open and understand its content. Thus, to safeguard data during transmission and storage, it is crucial that they are encrypted, preventing unauthorized access by third parties. Navigating the digital world securely is a priority and a shared responsibility.
