The present specification refers, as its title indicates, to a security device for computer equipment of the type used to control and program access over time to certain peripherals or services, comprising several service connector assemblies, peripherals, and multiple switching module capable of bidirectionally connecting the signals of the service connector with one, several or no peripheral connectors, a microcontroller module, a wireless digital communications module, and a RTC real-time clock module, being able to program the operating parameters, and connection and disconnection times for the multiple switching module or modules, from a remote control equipment, for example a mobile, the control of the device being independent of the computer equipment.
Campo de la invención field of invention
La invención se refiere al campo de los dispositivos de seguridad para equipos informáticos, especialmente a aquellos que permiten la conexión y desconexión programada en el tiempo de periféricos y servicios. The invention refers to the field of security devices for computer equipment, especially those that allow connection and disconnection programmed in time of peripherals and services.
Estado actual de la técnica Current state of the art
En la mayor parte de las empresas, e incluso a nivel particular y doméstico, es práctica habitual y recomendable realizar copias de seguridad diarias o periódicas, programadas a determinadas horas, del contenido del equipo informático, como por ejemplo un ordenador personal o un servidor en una red informática. En muchos casos se suelen utilizar dos discos duros externos, normalmente de tipo USB, de forma alterna, manteniendo uno conectado al equipo informático y el otro desconectado físicamente, y realizándose la copia de seguridad en el disco duro conectado. Diariamente una persona se encarga de cambiar el disco duro por el otro, de formal alternada, para que, en caso de que un virus entre en la red, o se produzca un acceso no autorizado a los datos, y se produzca una infección o un daño en los archivos de trabajo del equipo informático y en sus equipos conectado, al menos se dispone de la copia de seguridad de toda la información, limpia de virus y sin daño, realizada el día anterior que se encuentra en el disco duro que no estaba conectado físicamente al equipo informático. Para que la copia de seguridad anterior está lo más actualizada posible, es deseable que el intercambio entre discos se realice con la mayor frecuencia posible. Sin embargo, en muchas empresas grandes, el equipo informático servidor puede estar alejado del centro de trabajo, lo que produce el problema de que es necesario un desplazamiento de una persona que realice la operación de intercambio de discos, lo cual propicia que se produzcan incidencias (olvidos, exceso de confianza, accidentes), que a su vez originan problemas de seguridad. In most companies, and even at a private and domestic level, it is common practice and recommended to make daily or periodic backup copies, scheduled at certain times, of the content of the computer equipment, such as a personal computer or a server in a computer network. In many cases, two external hard drives, usually USB type, are used alternately, keeping one connected to the computer and the other physically disconnected, and performing the backup on the connected hard drive. On a daily basis, one person is in charge of exchanging the hard drive for the other, alternately, so that, in the event that a virus enters the network, or unauthorized access to data occurs, and an infection or damage to the work files of the computer equipment and its connected equipment, at least there is a backup copy of all the information, clean of viruses and without damage, made the day before that is on the hard drive that was not physically connected to the computer equipment. In order for the previous backup to be as up-to-date as possible, it is desirable that the swapping between disks be done as often as possible. However, in many large companies, the server computer equipment may be far from the workplace, which causes the problem that it is necessary for a person to travel to perform the disk swapping operation, which leads to incidents (forgetfulness, overconfidence, accidents), which in turn cause security problems.
Son conocidos diversos equipos de conmutación de periféricos, especialmente de discos duros, como por ejemplo el descrito en ES1056780 " Dispositivo selector de un disco duro de un ordenador con varios discos duros ", pero tienen el problema de que siempre requieren acción manual de una persona, bien mediante la conexión física, bien mediante el accionamiento manual de un conmutador o botón, o bien mediante un comando o combinación de teclas desde el mismo equipo informático. Esto, además de requerir intervención manual, siempre proclive a fallos, también origina que la conmutación se realiza en un equipo conectado a la red informática, por ejemplo Internet, y es además susceptible de ataque informático o entrada de virus incluso cuando está realizando la copia de seguridad. Various peripheral switching devices are known, especially for hard drives, such as the one described in ES1056780 "Selector device for a hard drive of a computer with several hard drives", but they have the problem that they always require manual action by a person. , either through the physical connection, or through the manual operation of a switch or button, or through a command or combination of keys from the computer itself. This, in addition to requiring manual intervention, always prone to failures, also means that the switching is carried out on a computer connected to the computer network, for example the Internet, and is also susceptible to computer attack or virus entry even when the copy is being made. of security.
En algunas instalaciones se utilizan temporizadores comerciales o equipos domóticos, como por ejemplo los descritos en WO2012109696 “Wireless power, light and automation centef’ o ES1188133 “Dispositivo para control y supervisión remotos de aparatos eléctricos", que cortan la alimentación de uno o varios dispositivos para controlar el acceso a Internet, datos, periféricos, pero, por su naturaleza cualquier persona los puede modificar o puentear sin que nos demos cuenta o quede registro de ello, además de que no desconectan físicamente el periférico del equipo informático ni están preparados para conmutar señales de buses informáticos, careciendo por tanto de la suficiente seguridad y fiabilidad, siendo una solución tosca y rudimentaria. In some installations, commercial timers or home automation equipment are used, such as those described in WO2012109696 "Wireless power, light and automation centef' or ES1188133 "Device for remote control and supervision of electrical appliances", which cut the power supply of one or more devices to control access to the Internet, data, peripherals, but, by their nature, anyone can modify or bypass them without us noticing or keeping a record of it, in addition to not physically disconnecting the peripheral from the computer equipment nor are they prepared to switch computer bus signals, therefore lacking sufficient security and reliability, being a rough and rudimentary solution.

Multiple switching for RJ45 signals.
Este dispositivo permite, que el módulo microcontrolador ordene la conexión o desconexión de dichos periféricos, mediante los módulos de conmutación múltiple, al equipo informático asociado a su conector de servicio, durante un tiempo programado y a unas horas programadas previamente. De esta forma, se puede regular automáticamente y sin intervención humana, el acceso tanto a periféricos como a servicios, como por ejemplo acceso a la red o a Internet, en el tiempo, y permitir asimismo que, mientras se conectan unos periféricos, por ejemplo discos duros externos para copia de seguridad, se desconecte el acceso a Internet del equipo informático, haciéndolo funcionar aislado, con lo cual se impide que una persona no autorizada, o un hacker, pudiera acceder desde el exterior a los discos duros USB y a sus copias de seguridad. También puede utilizarse para limitar el acceso a determinados contenidos de los discos duros o a Internet a determinadas horas, por ejemplo para limitar el tiempo de acceso para menores o personal no autorizado. This device allows the microcontroller module to order the connection or disconnection of said peripherals, through the multiple switching modules, to the computer equipment associated with its service connector, during a programmed time and at previously programmed times. In this way, it is possible to regulate automatically and without human intervention, access to both peripherals and services, such as access to the network or the Internet, over time, and also allow, while connecting peripherals, for example disks external hard drives for backup, disconnect access to the Internet of the computer equipment, making it work isolated, which prevents an unauthorized person, or a hacker, from accessing the USB hard drives and their backup copies from the outside. It can also be used to limit access to certain content on hard drives or to the Internet at certain times, for example to limit access time for minors or unauthorized personnel.
Ventajas de la invención Advantages of the invention
Este dispositivo de seguridad para equipos informáticos que se presenta aporta múltiples ventajas sobre los sistemas disponibles en la actualidad siendo la más importante que permite regular el acceso tanto a periféricos como a servicios, como por ejemplo acceso a la red o a Internet, en el tiempo, de una manera programable y automática, sin intervención personal, y permitir asimismo que, mientras se conectan unos periféricos, por ejemplo discos duros externos para copia de seguridad, se desconecte físicamente el acceso a Internet del equipo informático, haciéndolo funcionar aislado, impidiendo por tanto cualquier acceso no autorizado desde el exterior. This security device for computer equipment that is presented provides multiple advantages over currently available systems, the most important being that it allows regulating access to both peripherals and services, such as access to the network or the Internet, over time, in a programmable and automatic way, without personal intervention, and also allow that, while peripherals are connected, for example external hard drives for backup, Internet access is physically disconnected from the computer equipment, making it work isolated, thus preventing any unauthorized access from outside.
Otra importante ventaja es que todos los tiempos e intervalos son programables inalámbricamente desde un dispositivo externo de control, típicamente un móvil, pudiendo ir el acceso protegido mediante una oportuna contraseña. Another important advantage is that all the times and intervals can be programmed wirelessly from an external control device, typically a mobile phone, and access can be protected by means of a suitable password.
Otra ventaja de la presente invención es que el control de todos los procesos es completamente independiente del equipo informático, para mayor seguridad, no siendo accesible para ningún usuario del ordenador, de la red informática, o desde el exterior, impidiendo cualquier tipo de intrusión no autorizada o hackeo.. Another advantage of the present invention is that the control of all the processes is completely independent of the computer equipment, for greater security, not being accessible to any user of the computer, the computer network, or from the outside, preventing any type of unauthorized intrusion. authorized or hack..
Otra de las más importantes ventajas a destacar es que la conexión o desconexión de los dispositivos se realiza físicamente, mediante una desconexión eléctrica a nivel de hardware, siento por tanto imposible de vulnerar mediante programas troyanos o virus, a diferencia de las protecciones de acceso por software en el propio equipo informático. Another of the most important advantages to highlight is that the connection or disconnection of the devices is done physically, by means of an electrical disconnection at the hardware level, therefore I feel it is impossible to violate through Trojan programs or viruses, unlike access protection by software on the computer itself.
Asimismo otra ventaja añadida es que también puede utilizarse para limitar el acceso a determinados contenidos de los discos duros o a Internet a determinadas horas, por ejemplo para limitar el tiempo de acceso para menores o personal no autorizado. No debemos dejar de resaltar el funcionamiento completamente autónomo e independiente del equipo informático que protege, siendo aplicable tanto a equipos e instalaciones personales y domésticas, como a redes profesionales y servidores de datos. Also another added advantage is that it can also be used to limit access to certain contents of hard drives or to the Internet at certain times, for example to limit access time for minors or unauthorized personnel. We must not fail to highlight the completely autonomous and independent operation of the computer equipment it protects, being applicable both to personal and domestic equipment and installations, as well as to professional networks and data servers.
