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.

5G will trigger data consumption that will multiply by three in five years
18/03/2022In 2025, 25% of global data connections will be 5G, compared to 8% at the end of 2021, according to GSMA forecasts, which also indicate that this greater implementation will have a greater impact, even in Europe, North America, China and some Asian countries, where the percentage of 5G penetration would be higher in that date. Among the main consequences of the 5G expansion, will be a greater consumption of data by users, has said GSMA and if, at the moment, the data traffic per smartphone in a month, is 11.4Gb on average, the forecasts by 2027 place it at 41Gb, three times more. And according to the organization that brings together the telecommunications industry and organizes the MWC in Barcelona, as the population has access to 5G, there will be a significant increase in streaming consumption, favored by a sudden drop in download times that will become negligible. The use of remote health services, ultra-high definition television (4K/8K) and 5G as home broadband are also expected to grow.

What is the value of a Bitcoin?
11/06/2021Since Bitcoin first appeared in 2009, this digital currency not issued by any government or company, nor, under the umbrella of any kind of economic policy, has gained a foothold in the market and has already started to fit into existing legal frameworks. What gives Bitcoin its value? The great value of Bitcoin is that it is a decentralized and global currency, an alternative to fiat currencies (those issued by governments). All transactions with Bitcoins are public and each of these crypto currencies belongs exclusively to its owner, therefore, it is a currency that cannot be intervened by anyone. What can I do with Bitcoins? To date, with this cryptocurrency, it is possible to monetize all kinds of services, in addition to making investments, free or practically free of commissions, which in the medium to long term are proving attractive. This has made Bitcoin an asset in which to invest and an increasingly popular means of payment through which to transfer value from one user to another without losing friction along the way, going through an intermediary or paying a commission. What is the price of a Bitcoin? Like any other good, the price of a Bitcoin varies according to market demand, although the fact that it has been designed to behave as a deflationary asset and that its supply is limited to 21 million coins, facilitates that by the law of supply and demand itself, the Bitcoin exchange rate tends to rise continuously. As of June 9, at the time of writing this article, the Bitcoin value today is 30,007.86 euros, 3.4 times its price a year ago, when the Bitcoin to Euro conversion rate was 8,629.5 Bitcoins for 1 euro. In 2010 Bitcoin price was less than one Euro cent. What does the value of Bitcoin depend on? The value of Bitcoin depends on the trust and acceptance of users to use it, hence why Bitcoin is rising in value some days and not others. As Bitcoin has been implemented as a means of payment in multiple transactions and its popularity has grown, its value has grown in parallel. Likewise, when there have been news or events that have questioned, for example, the suitability of this crypto currency, its price has fallen. Like any other currency, the price of Bitcoin fluctuates and it is the users themselves who set it at the time of the purchase and sale transaction, which prevents the existence of a single price for Bitcoin, since it is not operated through a single platform as is the case with other currencies. Even so, buying and selling prices of Bitcoins tend to be quite similar. To know how much Bitcoin costs, there are several online platforms, known as "Bitcoin trading platforms" that report live the evolution of the value of the cryptocurrency. Is it safe and profitable to invest in Bitcoin? As with any other asset, investing in Bitcoins is profitable if we know how to do it at the right time. On the other hand, the Blockchain technology on which Bitcoin is based is reliable and difficult to manipulate, with no risk of being counterfeited, although some experts believe that the perfect, 100% inviolable system has not yet been created. In the cryptocurrency segment, convertibility is contemplated, so that Bitcoins can be exchanged for fiat currencies. What can I buy with Bitcoins? Over the last few years, a large number of companies have incorporated Bitcoin as an official method of payment for their goods and services From travel companies to ticket sales platforms for all kinds of shows, through gaming platforms, digital bookstores, software stores or even non-profit organizations already accept this digital currency. That is, Destinia, 13tickets, Gear Best, Shopify, Wordpress, Hostinger, Greenpeace,... among many other companies. eBay is currently considering adding Bitcoin as a method of payment. What is Bitcoin mining and how are Bitcoins generated? The users themselves through a totally decentralized system create Bitcoins. To become a bitcoin creator, computers with high computational capacity are needed to process and verify transactions and quickly solve the complex digital processes of generating the currency. This work is called mining and one of its best attractions is that the system offers "miners" rewards in Bitcoins in exchange for these services, which has made this activity very appealing for certain users. Is it profitable to mine Bitcoins in Spain? Bitcoin mining requires very powerful equipment, with high calculation capacities to solve operations, being nowadays totally inoperative for this operation the PCs of domestic or office use. The investment to mine Bitcoins requires, in addition, to assume the large power consumption required by this more powerful equipment, which makes Spain, at this time due to the high price of KW/h, an uninteresting market for mining Bitcoins. On the contrary, other locations such as China, Iceland, Iran or Georgia, where the Bitcoin mining business is in full expansion, are very interesting.
