Bot networks are a serious threat to cyber security, whose destructive behavior affects network performance directly. Detecting of infected HTTP communications is a big challenge because infected HTTP connections are clearly merged with other types of HTTP traffic. Cybercriminals prefer to use the web as a communication environment to launch application layer attacks and secretly engage in forbidden activities, while TLS (Transport Layer Security) protocols allow encrypted communication between client and server in the context of Internet provides. Methods of analyzing traffic behavior do not depend on payloads. This means that they can work with encrypted network communication protocols. Traffic behavior analysis methods do not depend on package shipments, which means they can work with encrypted network communication protocols. Hence, the analysis of TLS and HTTP traffic behavior has been considered for detecting malicious activities. Because of the exchange of information in the network context is very high and the volume of information is very large, storing and indexing of this massive data require a Big data platform.

Today, botnets have become a serious threat to enterprise networks. By creation of network of bots, they launch several attacks, distributed denial of service attacks (DDoS) on networks is a sample of such attacks. Such attacks with the occupation of system resources, have proven to be an effective method of denying network services. Botnets that launch HTTP packet flood attacks against Web servers are one of the newest and most troublesome threats in networks. In this paper, we present a system called HF-Blocker that detects and prevents the HTTP flood attacks. The proposed system, by checking at the HTTP request in three stages, a Java-based test, check cookies and then check the user agent, detects legitimate source of communication from malicios source, such as botnets. If it is proved the source of connection to be bot, HF-Blocker blocks the request and denies it to access to resources of the web server and thereby prevent a denial of service attack. Performance analysis showed that HF-Blocker, detects and prevents the HTTP-based attacks of botnets with high probability.

This study aimed to investigate the entrepreneurial intention among students of Bu-Ali Sina University in Hamedan and PNU surveys have been conducted within the overall framework. The sample consisted of 370 male and female students in agricultural disciplines in undergraduate students formed the College of Agriculture. To collect information, a questionnaire and a simple random sampling was used to select the sample. Cronbach's alpha coefficient to determine the reliability coefficient was calculated to vary from 850 students' entrepreneurial intentions are good. To analyze the data, descriptive and inferential statistical methods were used. The results showed that in general students of entrepreneurship spirit and intent of the high entrepreneurial intentions are more male students. The results of the analysis showed a correlation between gender, employment situation, risk appetite and economic barriers in interest income and a significant positive correlation with their entrepreneurial intentions can be seen. As well as the entrepreneurial intentions Mnadray difference was observed between the universities.

Following the publication of the corrigendum in issue 19(11) (HTTP: //hepatmon. com/en/articles/99558. html), the two recently added authors contacted the journal editor and claimed that the roles and order of authors of the published article (link: HTTP: //hepatmon. com/en/articles/15664. html) still needs to be changed. As we already stated in the corrigendum, adding those two new authors was performed due to the official and definite decision made by the Ethics Department of Legal Medicine Organization of Iran and approval of Iran National Committee for Ethics in Biomedical Research (HTTP: //ethics. research.ac.ir/) (published in HTTP: //hepatmon.com/en/articles/99558. html). ...

Background and purpose: Changes in medicine and medical education has yield to employment of new teaching methods and a shift to more student centered strategies in education. E-learning is one of these methods that can be used with greater flexibility and has the potential to enhance medical education. For our universities, using e-learning strategies in current curricula and continuous education is an inevitable issue and universities have begun their way in this era.Methods: we reviewed the websites of 9 type 1 Iranian universities of medical sciences including Ahvaz (HTTP://ajums.ac.ir), Iran (HTTP://www.iums.ac.ir), Isfahan (HTTP://www.mui.ac.ir), Kerman (HTTP://www.kmu.ac.ir), Mashad (HTTP://www.mums.ac.ir) Shahid Beheshti (HTTP://www.sbmu.ac.ir), Shiraz (HTTP://www.sums.ac.ir), Tabriz (HTTP://www.tbzmed.ac.ir) and Tehran HTTP://www.tums.ac.ir)universities of medical sciences. We tried to access these sites twice per week for two weeks. Two of the authors performed the search within these sites separately as follows: the homepages’ main menus were reviewed to find links to any kind of e-learning activity. This was done for the homepages of vice-chancellors of education too. Then if the site had a search option, the keywords of “e-learning”, “blended learning” and “electronic learning” were searched both in English and Persian. Then existing e-learning activities were assessed according to formal site utilization, providing interactive content, registration option for students and faculties and tracking option for students’ activities. The results of two authors were compared to reach a consensus.Results: Among these 8 universities, there was just one straight link to distance learning office in Shiraz University of Medical Sciences’ website and a link to online continuous medical education in Tehran University of Medical Sciences’ website. Others had no link for an office or a kind of e-learning activity in their homepages.Conclusion: We concluded from our search of Iranian medical universities that our universities have a long way toward deployment of effective e-learning in medical education and it seems that current efforts are performed individually, not as an organized activity. For establishment of successful e-learning systems, universities should pay more attention to this area, provide facilities and encourage qualitative implementation of e-learning in medical education.

Background and Objectives: Nowadays, the necessity of revising medical education programs towards accountability for societies’ needs are extensively considered. Given the necessity of dealing with this issue in the medical education curriculum of our country, Iran, the aim of the present article was to determine the different dimensions of socially accountable medical schools.Materials and Methods: In this review study, the Pubmed (HTTP: //www.ncbi.nlm.nih.gov/pubmed), Google scholar (HTTP: //scholar.google.com/) and Highwire (HTTP: //highwire.stanford.edu/) search engines were searched using “socially”, “accountable”, “medical” and “school” as the keywords. This search strategy retrieved 13 articles. Furthermore, it was tried that by altering the search strategy plus searching the reference lists of the retrieved articles, the most relevant and up-to-date articles were determined.Findings and Discussion: Evidences suggest that a social accountable medical school is a school in which educational, research, health and medical care programs are revised based on the relevant priorities of a society including health requirements and ethical guidelines. Moreover, the selection criteria of academic members and students plus appraisal programs of medical schools are done in a way that accountability in front of society is considered at the center of attention.Conclusion: Accountability in front of the societies' needs is one of the most important priority in revising medical education around the word. It is necessary that this goal is also adopted by other health sciences' schools.
