Abstract Malware brings a big security threat on the Internet today. With the great increasing malware attacks. Behavior-based detection approaches are one of the major method to detect zero-day malware. Such approaches often use API calls to represent the behavior of malware. Unfortunately, behavior-based approaches suffer from behavior obfuscation attacks. In this paper, we propose a novel malware detection approach that is both effective and efficient. First, we abstract the API call to object operation. And then we generate the object operation dependency graph based on these object operations. Finally, we construct the family dependency graph for a malware family. Our approach use family dependency graph to represent the behavior of malware family. The evaluation results show that our approach can provide a complete resistance to all types of behavior obfuscation attacks, and outperforms existing behavior-based approaches in terms of better effectiveness and efficiency.

Use Of The Internet

The use of the internet today has become a necessity, the most commonly used media to connect to the internet is a Wireless LAN network. For easy access to the network, DHCP service become a standard feature that must exist, because ordinary users no longer need to think about procedures for configuring IP addresses, all of which have been done automatically by the DHCP service. But it turns out that there is a security threat to DHCP service, namely DHCP Starvation attacks that can be exhausting the availability of IP addresses in DHCP service so that the configuration of IP address automatically can no longer be done on the client. Various methods such as authentication, cryptography, and machine learning are used by researchers in preventing DHCP Starvation attacks, but the issue of effectiveness and efficiency still opens up further research opportunities. In this research, packet filtering methods based on DSCP code applied to the Netfilter system are used to do prevention of DHCP Starvation attacks, this method has proven to be very effective in making prevention and more efficient when applied on small scale wireless networks such as at office networks and internet cafe.

Deep Learning Model

Recently, there has been a huge rise in malware growth, which creates a significant security threat to organizations and individuals. Despite the incessant efforts of cybersecurity research to defend against malware threats, malware developers discover new ways to evade these defense techniques. Traditional static and dynamic analysis methods are ineffective in identifying new malware and pose high overhead in terms of memory and time. Typical machine learning approaches that train a classifier based on handcrafted features are also not sufficiently potent against these evasive techniques and require more efforts due to feature-engineering. Recent malware detectors indicate performance degradation due to class imbalance in malware datasets. To resolve these challenges, this work adopts a visualization-based method, where malware binaries are depicted as two-dimensional images and classified by a deep learning model. We propose an efficient malware detection system based on deep learning. The system uses a reweighted class-balanced loss function in the final classification layer of the DenseNet model to achieve significant performance improvements in classifying malware by handling imbalanced data issues. Comprehensive experiments performed on four benchmark malware datasets show that the proposed approach can detect new malware samples with higher accuracy (98.23% for the Malimg dataset, 98.46% for the BIG 2015 dataset, 98.21% for the MaleVis dataset, and 89.48% for the unseen Malicia dataset) and reduced false-positive rates when compared with conventional malware mitigation techniques while maintaining low computational time. The proposed malware detection solution is also reliable and effective against obfuscation attacks.

Excessive Consumption

The present article is about the presence of the tv in the society, in general, and its potential as an important agent, such as the family and the school, on the children’s and young people’s development and education. Nowadays we live in a complex world of images with sound, the most of them transmitted by the tv, the cinema and the internet. The infantile universe is full of those images. This way we structured this article in four parts, refering some of the contents related with this subject. The first part describes the presence of the television in the children's daylife and their relationship with the magic box, even the identification that they make with its favourites characters, in order to understand the space that the TV occupies in their lives. The second part presents the different messages transmitted by the television. It is important to analyze the main risks and advantages of television, that is to say, in spite of some programs show bad values, foment the excessive consumption, expose the children to an atmosphere of violence and pornography, also entertains, accompanies, educates, informs, favours the access to the culture and allows to unite the family around a program. At last the third part, this one outlines the necessity to put the tele as a curricular resource in the school, to teaches the students how to analyze, how to criticize and to think about the texts and the news of the world today. The television, considered a powerful tool, is decisive in the communication, such in the formation of values and ideas as in the culture transmission. The function of the school is not to remain far from this factor, but to try to meditate, to understand and to decide its impact, in a better way, on the development of the children and youngs. As conclusion we can add that we’ve tried to aim some strategies that educators and parents will be able to work, united to the children and the youngs, so they could have a new look of the Tv’s world and that they could know how to make their own selection and how to have a critical attitude before the watched product.La presente comunicación se refiere a la presencia de la tele en la sociedad en general y a su potencial como agente importante de formación y educación, junto con la escuela y la familia, en la vida de los niños y de los jóvenes. Actualmente vivimos inmersos en un mundo complejo de imágenes con sonido, que recibimos muy especialmente a través de la tele, del cine y de Internet, los cuales hacen parte del cotidiano del universo infantil. Así, a fin de organizar algunos de los contenidos desde los que es posible enfocar el tema, estructuramos este artículo en cuatro partes. La primera parte describe la presencia de la tele a diario de los niños y su relación con la caja mágica, incluso la identificación que hacen de sus personajes favoritos, a fin de comprender el espacio que ocupa la tele en su cotidianidad. La segunda parte presenta los distintos mensajes transmitidos por la tele. Es importante analizar las principales riesgos y ventajes de la televisión, o sea, a pesar de algunos programas muestran antivalores de la tele: fomentar excesivamente el consumo, exponer a los niños a un ambiente de violencia y pornografía también entretiene, acompaña, educa, informa, favorece el acceso a la cultura y permite unir a la familia en torno a un programa. Cuanto a la tercera parte, plantea la necesidad de incorporar la tele como recurso curricular en la escuela, para que enseñe a los alumnos a analizar crítica y reflexivamente los textos mediáticos. La televisión es considerada como una herramienta poderosa, determinante en la comunicación, tanto en la formación de valores e ideas, como en la transmisión de cultura; la función de la escuela no es permanecer ajena a este factor, pero procurar reflexionar para comprender y decidir mejor su impacto en el desarrollo de los niños y jóvenes. Como conclusión podemos añadir que hemos tratado de apuntar algunas estrategias que educadores y padres podrán trabajar junto con los niños y los jóvenes, para que éstes tengan una nueva mirada del mundo de la tele y para que sepan hacer su propia selección y tener una actitud crítica ante el producto visionado.
