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.

Fundación Telefónica wants to convert the world's first website into a World Heritage Site
27/05/2022Fundación Telefónica is determined that the first website in history, the one of the british computer scientist Bernes-Lee, from 1990, could be declared a World Heritage Site by UNESCO and has announced a campaign to achieve this goal. The action named “ElSitio1155” identifies the Bernes-Lee website as a fundamental piece of the history and culture of humanity. And this is like this, becouse this website, in addition to be the first to exist, marked the birth of the World Wide Web, and also led to the first step to the connected world of today. If recognition is achieved, it would be the first time that UNESCO would do so to a virtual and non-geographical site as usual. Prior to the presentation of its official proposal, Fundación Telefónica has launched a support campaign through its social networks and communication channels to make everyone aware of the importance of this first website in the world, the pioneer of more than 1.9 million websites accounted for on December 31, 2021.

End-to-end encryption of Facebook Messenger and Instagram delayed until 2023
25/11/2021Security and privacy have become two of the main worries of the new virtual world. Meta, the new name of Mark Zuckerberg's company, has been working on end-to-end encryption system for Facebook Messenger and Instagram platforms and has just reported that finally this protection will not be ready until 2023. The delay, they explain, is due to their effort to ensure that end-to-end encryption will be the protection that all their messaging applications have by default, but at the moment only WhatsApp offers it. This technology means that only the sender and the receiver can know the content of a conversation. It's also known that end-to-end encryption has open the debate about privacy and collaboration with police investigations, specially in cases of child abuse. "As we implement end-to-end encryption, we will use a combination of unencrypted data in our applications, account information, and user reports to keep them secure in a way that protects privacy while assisting in public safety efforts" , has assured the Security director of Meta, Antigone Davis.

What is web hosting and why do you need it?
09/09/2021If you are thinking of creating your own website or if, on the contrary, you already have one and are looking for a better web hosting service, you probably have many doubts concerning web hosting: what exactly is it, what are its different types, why do I need it, etc. For this reason, here we offer you a clear and simple guide to web hosting. What is web hosting? Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet so that it can be consulted at any time and from any place and device. The content of the websites is stored, therefore, in web servers. These servers allow the content to be accessible via the World Wide Web. For all those who do not know the term, a web server is a piece of computer equipment that is much more powerful than any conventional computer and that is connected to the Internet 24 hours a day to enable access to the contents it stores. Different types of web hosting are offered based on the web server: shared hosting, VPS, cloud hosting, WordPress hosting, elastic hosting, etc. These services are offered by web hosts such as Webempresa, which provide space on a server for use by clients. Why do you need web hosting? Web hosting allows your website to be always online and available worldwide and for everyone. Therefore, even if you can afford to buy your own server and have a fast internet connection, it is advisable to hire a web hosting service, as it will be much cheaper. Web hosts have their own servers to host their clients' websites. These servers are located in a Data Processing Center (DPC): an infrastructure that has the most advanced security systems and stable and secure internet connections, which prevent errors in the services. What are the different types of web hosting? Although there are different types of web hosting in the market, the most common are the following: shared hosting, dedicated hosting, VPS (Virtual Private Server) hosting, cloud hosting, reseller hosting, and WordPress hosting. Each of them meets the needs of a particular group of customers. Shared hosting is the most basic type of web hosting. The provider rents small spaces on a single server to different websites. In this way, all customers have their own space to host their content, while sharing server resources such as CPU, processor, RAM, bandwidth, or IP address. In contrast, a dedicated hosting service is a type of web hosting in which the client leases an entire server and does not share it with anyone else. Although shared hosting works very well, a dedicated server stands out because it is never affected by existing traffic and because it has a higher level of security. A virtual private server (VPS) is basically a server running within a server. One physical server hosts multiple virtual servers, each isolated from the others. Each VPS runs its own operating system, independent of the others. The features offered by a virtual private server are very similar to those of shared hosting. At the same time, it offers all the benefits of a dedicated server. Cloud hosting works in a very similar way to the "cloud" where we store all kinds of documents. This is because all the resources that are used to collect the information of a website are executed from a cloud server. The main difference between cloud hosting and other web hosting types is that, in this case, you only pay for the services you use. Reseller hosting is another type of web hosting. It is basically white-label web hosting. A person buys hosting from a provider and then resells those services to his/her clients. This allows the creation of hosting plans and external domains or subdomains. The last type of web hosting we will talk about here is email hosting, which allows you to register a domain name and therefore have a professional email service. This type of web hosting is highly recommended for businesses or individuals that intend to convey an image of seriousness and trust. Thus, thanks to email hosting, you will be able to have a personalized email address, more storage space, and a higher level of security.

Macro cyber-attack affects more than 350 companies worldwide
07/07/2021The number of companies that have suffered from the REvil macro cyberattack now exceeds 350 organizations worldwide from which the cybercriminals are demanding 70 million in bitcoins to provide them with a universal decryptor to restore their data. The attack was conducted through the update system of IT services software company Kaseya, which REvil exploited to spread and hide ransomware. The virus was leaked to TI Kaseya resellers and from there has reached all end customers using their software. The official data provided by TI Kaseya sets the number of affected companies at 350, although other sources such as the cybersecurity company ESET talk about more than 1,000, including some Spanish organizations, although no names have been disclosed. It has been made public that one of the companies most affected by the cyberattack has been the Swedish supermarket chain Coop, which has had to close its more than 800 points of sale for a few days due to the impossibility of using its cash registers or charging customers. Based on Sophos threat intelligence, REvil has been active in recent weeks and is currently the dominant ransomware gang involved in Sophos' defensively managed threat response cases. Prior to this latest attack, they were also responsible for the one suffered by meat company JBS, which forced the cancellation of all work shifts at the company's slaughterhouses in the US. JBS paid up to 11 million to restore normal operations. These macro cyber-attacks are in addition to other recent and highly significant ones, such as the one perpetrated by the hacker group DarkSide, which forced the preventive shutdown of the largest oil pipeline network in the United States, Colonial Pipeline, endangering the supply of fuel in a large part of the country, or the one suffered by the SEPE and the Ministry of Labor in Spain a few weeks ago.
