Abstract
Security attacks using USB interfaces and devices are becoming more advanced, which boost efforts to develop counter measures in order to protect systems and data. One of the most recent attacks using USB devices is the BadUSB attack, performed by spoofing the device’s firmware and allowing the attackers to execute a set of malicious actions, e.g. an USB storage device could be mounted as USB keyboard in order to inject malicious scripts into the system. This paper proposes a protection agent against BadUSB attack developed for Windows operative systems. It allows a user to check the class of an USB device ready to be mounted, though enabling the detection of a potential attack if the expected functionality of the device does not match with its class type. The results show that the proposed protection agent is capable of detecting potential intrusions by blocking the installation of the device, scanning the device for something that identifies it, searching for a description locally and finally warning the user about the device meaning that all devices must be approved by the user when plugged in if the system protection agent is running.

Abstract
The security standard ISO/IEC 27001 provides orientations to support organizations to set adequate best practices in information security management, specifying requirements that enable the appropriate selection and implementation of security controls. This standard assists organizations to protect their information assets, achieve their adequate levels of security and thus help them to succeed their business goals. Currently, an increasing number of Portuguese organizations seek to comply ISO/IEC 27001:2013 standard and obtain the respective certification. This paper presents the result of a research conducted in order to detail the main difficulties and limitations evidenced by Portuguese organizations while meeting the ISO/IEC 27001:2013 standard. Moreover, this paper provides discussion on the results obtained, to better understand the progress and status quo of this standard implementation. From the research conducted it can be seen that organizations are becoming heavily concerned with information security issues, mainly due it to the recent cybersecurity incidents occurred. Additionally, certification is recognized as an important instrument to give confidence and demonstrate to all organizational' customers, suppliers and stakeholders that information security components are verified and organized within the organization.

Abstract
The orofacial complex is the primarily link between the instrument and the instrumentalist when performing the musician's embouchure. The contact point is established between the saxophonist lower lip, the upper maxillary dentition and the mouthpiece. The functional demands of the saxophone player and consequent application of forces with an excessive pressure can significantly influence the orofacial structures. A thermographic evaluation was performed to an anatomical zone vital for the embouchure, such as the lip of the saxophonist. Substantial temperature changes occurred before and after playing saxophone. The specificity of the embouchure regarding the position of the lower lip inside the oral cavity, the anatomy and position of the central lower incisors can be some of the factors involved in the origin of the existing temperature differences on the thermographic evaluation.

Abstract
We present DIGItal sTeps (DIGIT), a system for assisting in the creation of footstep sounds in a post-production foley context—a practice that recreates all diegetic sounds for a moving image. The novelty behind DIGIT is the use of the acoustic (haptic) response of a gesture on a tangible interface as means for navigating and retrieving similar matches from a large database of annotated footstep sounds. While capturing the tactile expressiveness of the traditional sound foley practice in the exploration of physical objects, DIGIT streamlines the workflow of the audio post production environment for film or games by reducing its costly and time-consuming requirements. © 2018, Springer Nature Switzerland AG.

Abstract
We present MusikVerb, a novel digital reverberation capable of adapting its output to the harmonic context of a live music performance. The proposed reverberation is aware of the harmonic content of an audio input signal and ‘tunes’ the reverberation output to its harmonic content using a spectral filtering technique. The dynamic behavior of MusikVerb avoids the sonic clutter of traditional reverberation, and most importantly, fosters creative endeavor by providing new expressive and musically-aware uses of reverberation. Despite its applicability to any input audio signal, the proposed effect has been designed primarily as a guitar pedal effect and a standalone software application. Copyright
