Security breaches that put our privacy at risk, leaks of our data, passwords... are incidents that happen more and more often. Protecting ourselves from these information leaks is often beyond our reach, but this does not mean that we should not try to take measures to protect our data. DNS-over-TLS can be very helpful in encrypting our communications, making them much more secure.

Not only is the interpretation of network traffic crucial to analyse the safety and performance of a network structure, but also for other tasks, such as incident management, the optimisation of our network infrastructure or for didactic purposes. In order to do so, it is necessary to have dissectors that help separate each of the fields that make up a protocol, and allow them to be individually analysed.
It is increasingly common to find malware related to cryptocurrencies, either to use them as payment currency in extortions and illegal activities, cryptocurrency theft or infiltrate on systems and equipment from all areas to take advantage of the resources of the victims' equipment to undermine cryptocurrency
The problems originating from the application of patches in an industrial setting have consequently led to them being rejected by the operators. For years they were practically abandoned, but thanks to the support from security companies and IT departments they are now receiving their due credit.
The increasing number of attacks to industrial networks forces us to analyse their behaviour so that we can implement measures to mitigate said attacks. One of the options used to learn about the behaviour of attacks is the deployment of honeypots. This article deals with the advantages and challenges of this technology when used in industrial environments.
In the article: Security Model in OS X (I), we introduced the operating system’s main accumulated security features accumulated up to Yosemite (OS X 10.10). With the latest version, launched in September 2015, an interesting new security feature appears in the system. System Integrity Protection (SIP) As of OS X 10.11 (El Capitan), Apple is tightening security measures even further with the...
Security measures in OS X have been incorporated into the operating system base, with functions added and improved upon as different versions are published. Together,these measures form a layered model that reinforce the basic outline of typical POSIX permissions and provides a mechanism covering various aspects of protection against security threats. Let’s see how this system works. First line...
There are still a great number of websites that do not use SSL/TLS certificates to encrypt their connections; this has been a problem in web communications security for years. There are various reasons for this; however, perhaps the most important is the fact that historically, having an SSL certificate was unviable economically, particularly for personal websites, SMEs, or small online shops...
Control system applications have adapted and evolved, both in terms of changes to base software (operating system) and devices. Seizing on this need for change, applications have also adapted, and can now work online and share information in the cloud.
Industry 4.0 is a state of development in the management and organisation of the entire value chain process in the manufacturing industry. This article examines the relationship between cybersecurity for industry 4.0 and the challenges that lie ahead for it in advanced manufacturing.
