WiFi Security: Assessment of threats in wireless networks
08/03/2024Wifi connectivity has gone from being limited to restricted environments to becoming omnipresent in virtually every aspect of our daily lives. The ability to connect to the Internet from anywhere, be it at home, in a café, at work, in public spaces, or even in-flight, has enhanced the convenience in our daily lives. Moreover, the expansion of Wifi networks and the use of new manufacturing technologies now allow the interconnection of devices, leading to the significant rise of the Internet of Things (IoT) and providing users with more comprehensive control over their digital environments. However, this proliferation of Wifi networks has also given rise to new threats that require careful evaluation and effective security strategies to ensure secure and risk-free Wifi connections for our data and information. Common Wifi security threats include data interception Man-in-the-Middle (MITM) attacks One of the fundamental challenges in Wifi security is preventing MITM attacks, where an intruder inserts themselves into the communication between two parties, compromising the integrity and confidentiality of sensitive data such as passwords and financial information. Spoofing of access points Hackers can create fake Wifi networks that mimic legitimate ones to attract unsuspecting users. Once connected to these malicious networks, our data can be captured by cybercriminals who may sell or misuse it for illicit purposes. Tips for achieving a secure Wifi connection: Strengthen authentication and use security protocols Prioritize strong encryption for networks to protect confidential information transmitted through it. WPA (Wifi Protected Access) encryption uses stronger algorithms than its predecessor, WEP (Wired Equivalent Privacy), making it more difficult for hackers to intercept and decipher data. Advanced security protocols like WPA3 provide individualized data encryption and advanced two-factor authentication (2FA) methods, adding an extra layer of security by requiring additional verification. Device management Properly manage and monitor devices connected to Wifi networks to minimize risks associated with the large number of connected devices in homes and businesses. Regularly update the router firmware and all connected devices to address potential vulnerabilities. Segmentation of the network to separate critical devices from less secure ones also helps mitigate the risk of threat propagation. Secure Router Configuration The router secure configuration is what will ensure the robustness and overall security of a wireless network. The router, being the first point of contact for devices connected to the Internet, acts as the first line of defence against potential attacks. For this reason, it is important to understand that the proper configuration of the router not only guarantees a stable and efficient connection but also establishes a protected environment that safeguards the integrity and privacy of our data. How to configure the router securely? To ensure a correct and secure configuration of the router, it is recommended to: Change the default username and password of the router, as these are easily accessible to attackers. Use strong passwords containing a combination of letters, numbers, and special characters. Disable remote administration to prevent cybercriminals from accessing the router externally. Enable WPA2 or WPA3 encryption instead of the outdated WEP for enhanced network security. Optionally, disable SSID broadcast to make the network less visible and harder to detect by hackers. Keep the router firmware updated to address vulnerabilities and improve overall device security. By following these steps, you will strengthen the security of your wireless network and reduce the chances of experiencing unwanted attacks or intrusions.

Google launches ChromeOS Flex to give a second life to outdated computers
21/07/2022Google has just introduced ChromeOS Flex, a new version of their cloud-based operating system that will allow "rejuvenating" Windows and Mac computers that have become available. The system must be downloaded directly from the web and can be installed on the computer via USB or the company network. ChromeOS Flex is now ready to give outdated Windows and Mac computers a second life. At the moment, Google has already certified nearly 300 devices compatible with ChromeOS Flex, from leading brands on the market such as Apple, Acer, Dell or Microsoft. Although Google has advanced that not having the certification does not prevent the installation of the operating system on our old computer. Some of the services offered by this operating system are, the protection against ransomware and malware; background updates; remote management of applications and, of course, the possibility of giving a new life to an outdated computer. “By installing ChromeOS Flex on an older computer, you're not only getting a great experience, you're also contributing to an important cause. Every year 40 million tons of electronic waste is generated worldwide, which is equivalent to throwing away 800 laptops every second. Updating devices to ChromeOS Flex instead of completely replacing them is one way to reduce this waste.

Amazon allows you to send gifts without knowing the recipient's address
06/10/2021In the United States, Amazon is testing a new service that allows the costumers to send surprise gifts without knowing the recipient's address. To do it, the buyer, who must be an Amazon Prime user, just has to choose the product on the platform, check the option "Let the recipient provide their address" and provide an email or mobile phone number of the person to whom you want to send the surprise gift. Then Amazon contacts the recipient by either of these two ways and informs him or her that a gift has been sent. To accept the package, the person must have an Amazon account and provide the marketplace his or her postal address so the gift can be delivered. If the person accepts the gift, or its equivalent in a gift card to spend on Amazon, immediately the product will be charged to the buyer's account and a conventional shipping process will start. But, if the person who has received the message informing about the gift does not answert or rejects the shipment, the order will be cancelled, and the person who bought the product will not pay anything. Now, this service is only available in the United States and only works with purchases made via mobile phone.
