Deep learning model for distributed denial of service (DDoS) detection

Distributed denial of service (DDoS) attacks is one of the serious threats in the domain of cybersecurity where it affects the availability of online services by disrupting access to its legitimate users. The consequences of such attacks could be millions of dollars in worth since all of the online services are relying on high availability. The magnitude of DDoS attacks is ever increasing as attackers are smart enough to innovate their attacking strategies to expose vulnerabilities in the intrusion detection models or mitigation mechanisms. The history of DDoS attacks reflects that network and transport layers of the OSI model were the initial target of the attackers, but the recent history from the cybersecurity domain proves that the attacking momentum has shifted toward the application layer of the OSI model which presents a high degree of difficulty distinguishing the attack and benign traffics that make the combat against application-layer DDoS attack a sophisticated task. Striding for high accuracy with high DDoS classification recall is key for any DDoS detection mechanism to keep the reliability and trustworthiness of such a system. In this paper, a deep learning approach for application-layer DDoS detection is proposed by using an autoencoder to perform the feature selection and Deep neural networks to perform the attack classification. A popular benchmark dataset CIC DoS 2017 is selected by extracting the most appealing features from the packet flows. The proposed model has achieved an accuracy of 99.83% with a detection rate of 99.84% while maintaining the false-negative rate of 0.17%, which has the heights accuracy rate among the literature reviewed so far.

A periodical analysis of e-government maturity in Saudi Arabia

Findings The results revealed remarkable improvements in the maturity level of online services provided by the government websites of Saudi Arabia. Practical implications The relationship between e-government use and investment decisions appears to be bidirectional, as greater levels of investment seem to offer more opportunities for service improvement. Originality/value The outcomes are expected to assist executive authorities in understanding the current situation of e-government and plan appropriate strategic suggestions and development.

User Authentication Method via Speaker Recognition and Speech Synthesis Detection

As the Internet has been developed, various online services such as social media services are introduced and widely used by many people. Traditionally, many online services utilize self-certification methods that are made using public certificates or resident registration numbers, but it is found that the existing methods pose the risk of recent personal information leakage accidents. The most popular authentication method to compensate for these problems is biometric authentication technology. The biometric authentication techniques are considered relatively safe from risks like personal information theft, forgery, etc. Among many biometric-based methods, we studied the speaker recognition method, which is considered suitable to be used as a user authentication method of the social media service usually accessed in the smartphone environment. In this paper, we first propose a speaker recognition-based authentication method that identifies and authenticates individual voice patterns, and we also present a synthesis speech detection method that is used to prevent a masquerading attack using synthetic voices.

URGENSI PERSONAL BRANDING BAGI PUSTAKAWAN DI ERA PANDEMI

As a result of the Covid-19 outbreak, libraries must change their habits and order in providing library services. Library services, which were initially carried out in person or on the spot, were turned into online services to facilitate and provide convenience for users and librarians. Librarians are expected to be more creative in creating new innovations in providing online services to users. Librarians must still be able to provide excellent service to users even with various existing limitations, both librarians, infrastructure, and library collections. In the midst of the limitations of excellent service, the librarian is the key to this excellent service. Librarians must have a brand. How the librarian shows brand personality, brand-ability, brand value, and has a stimulus that produces positive perceptions. The brand of personality to build is one that is friendly, cooperative, forgiving, understanding, and good on good terms with other people. Librarians must also hone their brand personality in terms of being systematic, careful, thorough, responsible, and disciplined. Librarians should also have less negative emotionality, so that they are relatively balanced, calm, steadfast, and feel safe. Librarians must be sociable, articulate, assertive, and open to new relationships. besides that the librarian must have a high, to listen to new ideas and change ideas. The brand of librarian abilities that must be built is solving problems systematically, being able to find and finding creative and original ideas, managing people, coordinating with other people or teamwork, regulating and controlling emotions, being able to draw decisions, under any conditions, have a service or service orientation, negotiate, have cognitive flexibility or are able to think spontaneously in response to adjusting to situational needs. The librarian's brand value that must be built is the value of integrity and leadership. In terms of integrity, librarians must value honesty in speaking and acting; be able to balance/be consistent between thoughts, words, and actions; fair in treating others; have a high dedication to the institution; can always be trusted in carrying out the mandate and carrying out daily tasks.

It is recommended that more attention be paid to improving the quality of services provided to tourists for developing smart destinations.

Virtualization of Research Data Services during the COVID-19 Pandemic as an Opportunity to Enhance Research Data Support

For Canadian academic libraries, the emergence of the COVID-19 pandemic necessitated an unprecedented switch to virtual services. An abrupt halt to in-person activities required almost all libraries to utilize new technologies in order to continue serving patrons. While the Academic Data Centre (ADC) has traditionally offered both physical and online services, with the emergence of the pandemic, the ADC pivoted to exclusively online service provision. Through new initiatives such as remote desktop access to statistical software, embedded virtual spaces for consultation and breakout discussions, online workshops and teaching, and the use of social media--the Academic Data Centre emerged successful in supporting student and faculty data needs. While virtually scaling up data services was essential to avoid disrupting researchers working with data, the shift to online services also presented an unexpected opportunity to reflect meeting the data needs of users and, in turn, strategize innovative future data service delivery. Three themes emerged from our reflection: emphasis on greater accessibility; more flexible instruction; and the benefits for cultivating a data community. As emerge from the pandemic, the ADC expects to further embrace newly implemented technologies and virtual services to further scale and augment research data service support.

COVID 19 Pandemic and the Library Online Services

The purpose of this study is to describe the experiences of St. Scholastica's College Manila High School librarians in implementing library online services during the COVID-19 Pandemic. The researcher used a descriptive research design and employed Document Analysis and Thematic Analysis vis-a-vis the respondents' answers on the electronic questionnaires. It was revealed, through this study, that the roles and responsibilities of the SSC Manila HS librarians were technologists, online learning support professionals, instructional partners, and game-based learning developers. On the other hand, they experienced challenges such as having limited transactions and time constraints in delivering library online services and the opportunities of having proactive team culture and providing appropriate and innovative services to their clientele. With these findings, the following are recommended for better library online services of the school libraries and librarians. First, librarians and staff's technical competencies and skills must continuously be honed. Second, the library's online services must also be evaluated annually by the students and faculty members. Third, the librarians and staff must explore more technological applications or apps and learning management systems. Lastly, further research studies are recommended in relation also to delivering library online services that can be in the contexts of other types of libraries, most especially their experiences so that there will be a deeper and bigger understanding of the roles and responsibilities, and the challenges and opportunities of librarians during the COVID-19 Pandemic.
