Information security is gradually becoming an area that plays an important role in our daily lives as information and communications technology assets grow with increasingly connected environments. Increasingly we have information from society having their data leaked due to information security flaws in both hardware and software of ICT assets. To identify failures of ICT assets, through the detection of malicious traffic, this chapter proposes a black-box-based framework that aims to detect malicious traffic. The black-box method allows monitor the network without accessing the software or hardware details. In the proposed framework, information security and network resource usage are used together in order to provide a reliable detection of malicious traffic. Firstly, the authors collected network traffic information, generating a dataset from open source networking tools. The proposed detection scheme can identify risks and threats like malware, suspect traffic, and others. The scheme was validated verifying the correlation between network security alerts and network resource usage.

The security of today's technological environments is highly dependent on the proper behavior of the various Information and Communications Technology assets that make up them – where ICT assets are used to contemplate all kind of hardware and software capable of performing computational processing and engaged in information technology and communications activities. The term ICT refers to the combination of computer with telecommunications technologies and has in computer networks, and especially on the Internet, its greatest expression (Miranda, 2016). In fact, the inadequate functioning of a simple element of a computer system, whether hardware or software, can compromise the entire security of that system. It is therefore essential to develop mechanisms to ascertain and attest that ICT assets meet desirable security requirements. This objective, however, is a huge challenge, as the ICT assets used in today's computer systems become increasingly complex. ICT assets are at into increasingly critical activities and relevant to the society's well-being.

One approach that has gained increasing strength in the compliance of products, services, processes, systems and people to regulatory requirements is the implementation of Conformity Assessment Programs (CPAs) (Fernandes, 2011). These programs deal systematically, using traditional quality management techniques, such as inspections, tests, sampling and audits, to analyze compliance with pre-established requirements in standards and regulations, for each product, process, service or professional under evaluation. Conformity Assessment programs are already used in various areas to verify compliance with the most diverse types of requirements, including calibration of measurement instruments, energy efficiency, electromagnetic compatibility, radiation detection, thermal insulation, ergonomics and civil construction (Inmetro, 2019).

In the area of ICT asset security, the use of CPAs to verify compliance with cybersecurity requirements has gained a strong impulse in the last decade with the publication of international standards ISO/IEC 15408-1:2009 (Information technology - Evaluation criteria for IT security) and ISO/IEC 19790:2012 (Information technology - Security techniques - Security requirements for cryptographic modules) (Leszczyna, 2018). However, even if the area of information security is moving towards international standardization and the search for systematic testing procedures for conformity assessment, the evaluation of ICT assets includes advanced technical challenges arising from the complexity of the behavior of such assets, which requires research to develop systematic and conclusive tests.

In recent years, there have been cases of compromised ICT assets (Kirtley & Memmel, 2018). Several models of babysitting suffered security incidents, where in some cases there was the sending of scary audios to children, in addition to the theft of access credentials to Apple and Google stores, and the improper obtaining of the authorization of other users to remotely view and control the monitor. According to (Cziesla, Kemper, Muntermann, & Sinanaj, 2015), several companies have had their data breached by the NSA through security breaches in ICT assets. In (Restuccia, D'Oro, & Melodia, 2018), it has been proven that internet-connected cars, through Internet of Things (IoT) devices, can be controlled remotely. More worrying cases, however, involve medical devices and can have fatal consequences in the event of failure (Restuccia, D'Oro, & Melodia, 2018).

Key Terms in this Chapter

Virtualization: It allows you to use a physical machine’s full resource by distributing its capabilities among many users, environments, or virtual machines.

Cybersecurity: It is the organization and collection of resources, processes, and structures used to protect cyberspace from security events.

Information Security: It is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of organization's information.

ICT Assets: All kind of hardware and software capable of performing computational processing and engaged in information technology and communications activities.

Network Traffic: It refers to the amount of data moving across a network at a given point of time.

Conformity Assessment: It encompasses any procedure used, directly or indirectly, to determine that the requirements pertaining to technical regulations or standards are complied.

Security Event: Any observable or detectable occurrence relevant to information security. This can include attempted attacks or lapses that expose security vulnerabilities.

Malicious Traffic: Any suspicious connection or content created or received over the network. Malicious traffic is a threat that creates a security event.

Black-Box Test: Test performed without knowledge of the internal workings of the software in which it examines the fundamental aspects of the system.
