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.

Europe will have its own satellites constellation to guarantee secure communications
13/12/2022With the sights set on 2027, the EU has closed a provisional agreement about the regulation of secure connectivity throughout its territory, which will include the deployment of a constellation of satellites that will ensure communications, especially in the event of cyberattacks or natural disasters that affect critical infrastructure. The plan, linked with the 'Global Gateway' strategy from the UE, that will allow the provision of affordable Internet access throughout Europe, will provide, also, secure connectivity in geographical areas of strategic interest, such the Arctic region and Africa, and services to protect the critical infrastructures of the Member states, too. The objective, according to the EU, is to ensure improvements in people's daily lives, identifying reliable and secure communications as the cornerstone of the EU's strategic autonomy.

Chrome flies on Mac
16/03/2022New features introduced in the las version of Chrome browser have made it up to 43% faster on Mac computers, according to Apple's Speedometer browser responsiveness benchmark. The M99 version of Chrome introduces, as main change, the use of the “ThinLTO” build optimization technique, which has integrated parts of the base code that are critical for speed, even when they span multiple files or libraries. This integration, according to the Speedometer comparison, has meant that the new Chrome is generally 7% faster than Safari, and that its graphic performance is up to 15% higher. In addition, Google ensures that the loading time of web pages has been reduced by 15% on Android, where the introduction of the 'freeze-dried' tab loading process in the browser has also reduced the startup times by 13%.
