Securing cyber infrastructures has become critical because they are increasingly exposed to attackers while accommodating a huge number of IoT devices and supporting numerous sophisticated emerging applications. Security metrics are essential for assessing the security risks and making effective decisions concerning system security. Many security metrics rely on mathematical models, but are mainly based on empirical data, qualitative methods, or compliance checking, and this renders the outcome far from satisfactory. Computing the probability of an attack, or more precisely a threat that materialises into an attack, forms an essential basis for a quantitative security metric. This paper proposes a novel approach to compute the probability distribution of cloud security threats based on a Markov chain and Common Vulnerability Scoring System. Moreover, the paper introduces the method to estimate the probability of security attacks. The use of the new security threat model and its computation is demonstrated through their application to estimating the probabilities of cloud threats and types of attacks.

Approximate computing (AC) represents a paradigm shift from conventional precise processing to inexact computation but still satisfying the system requirement on accuracy. The rapid progress on the development of diverse AC techniques allows us to apply approximate computing to many computation-intensive applications. However, the utilization of AC techniques could bring in new unique security threats to computing systems. This work does a survey on existing circuit-, architecture-, and compiler-level approximate mechanisms/algorithms, with special emphasis on potential security vulnerabilities. Qualitative and quantitative analyses are performed to assess the impact of the new security threats on AC systems. Moreover, this work proposes four unique visionary attack models, which systematically cover the attacks that build covert channels, compensate approximation errors, terminate normal error resilience mechanisms, and propagate additional errors. To thwart those attacks, this work further offers the guideline of countermeasure designs. Several case studies are provided to illustrate the implementation of the suggested countermeasures.

Multilevel Classification

Cloud Security was provided for the services such as storage, network, applications and software through internet. The Security was given at each layer (Saas, Paas, and Iaas), in each layer, there are some security threats which became the major problem in cloud computing. In Saas, the security issues are mainly present in Web Application services and this issue can be overcome by web application scanners and service level agreement(SLA). In Paas, the major problem is Data Transmission. During transmission of data, some data may be lost or modified. The PaaS environment accomplishes proficiency to some extent through duplication of information. The duplication of information makes high accessibility of information for engineers and clients. However, data is never fully deleted instead the pointers to the data are deleted. In order to overcome this problem the techniques that used are encryption[12], data backup. In Iaas the security threat that occurs in is virtualization and the techniques that are used to overcome the threats are Dynamic Security Provisioning(DSC), operational security procedure, for which Cloud Software is available in the market, for e.g. Eucalyptus, Nimbus 6.

Poor design has been a major source of software security problems. Rigorous and designer-friendly methodologies for modeling and analyzing secure software are highly desirable. A formal method for software development, however, often suffers from a gap between the rigidity of the method and the informal nature of system requirements. To narrow this gap, this paper presents a UML-based framework for modeling and analyzing security threats (i.e. potential security attacks) rigorously and visually. We model the intended functions of a software application with UML statechart diagrams and the security threats with sequence diagrams, respectively. Statechart diagrams are automatically converted into a graph transformation system, which has a well-established theoretical foundation. Method invocations in a sequence diagram of a security threat are interpreted as a sequence of paired graph transformations. Therefore, the analysis of a security threat is conducted through simulating the state transitions from an initial state to a final state triggered by method invocations. In our approach, designers directly work with UML diagrams to visually model system behaviors and security threats while threats can still be rigorously analyzed based on graph transformation.

The Government

The community is responsible for the implementation of the community early awareness, meanwhile the government is obliged to facilitate it. A good role of the Community Early Awareness Forum or Forum Kewaspadaan Dini Masyarakat (FKDM) followed up by the government can save the community from security threat or disaster and minimize losses by anticipating the security threats and disaster. This research uses qualitative approach. Concept operationalization in this research refers to the used strategy, the SWOT analysis. The FKDM strategies in social conflict early prevention are: 1) inserting early warning system by increasing institutional capacities which include three elements; government, private sector, community through dialogue, 2) National Unity and Politics Agency or Badan Kesatuan Bangsa dan Politik (Kesbangpol) of DKI Jakarta actively making dialogue persuasively and finding solution, 3) budgeting of conflict handling according to the Government Regulation gives opportunity to strengthen community resilience to protect the community, encourage community participation, handle social conflict, and preserve local wisdom to maintain peace.

This paper presents the ongoing research and, deals, in the framework of interdisciplinary scientific research, with various military and non-military threats and their negative impact on the security of contemporary human society. In this research, the authors point out the continuous deterioration of the global and regional security environment and the growth of symmetric and asymmetric security threats with focus on the air transport, and the resulting negative consequences for the security of the states and their citizens. In order to contribute to the development of security science, the authors examine the issues of terrorism as an asymmetric security threat, focusing in particular on terrorism and terrorist activities of the air transport and measures taken to eliminate terrorism in the airspace.

Cyber Threat Intelligence

This research work was conducted to examine critically and systematically cyber threat intelligence challenges and prospects in Nigeria. It judges the value and relevance of cyber threat intelligence in the society where they are lacking in providing necessary information. Dealing with these challenges that may cause threat intelligence to be useless has become a major concern to Nigeria. The work was intended to achieve the following objectives: to examine the nature of cybersecurity in Nigeria, to analyse the cybersecurity threats that can disrupt the functioning of the country, to identify the challenges facing the Nigeria cyberspace and the conduct of a cyber threat intelligence analysis, to discuss the means by which cyber threat can be used to boost Nigeria’s National Security Policy, to make recommendations to preserve important intelligence capabilities while ensuring the protection of its critical infrastructures through the use of threat intelligence. The scope of the study was limited to the period 2009 – 2019. The research was analytical. Relevant data were collected from both primary and secondary sources of data. The data analysis used the percentage instrument and the following conclusions were drawn: that threat data overload, threat data quality, privacy and legal issues and interoperability issues are some of the challenges of cyber threat intelligence; also, the need to continually invest in research, build local cyber threat management infrastructure and enhance the ability to anticipate, detect, respond and contain information security threats is very crucial.
