Evil-hunter:基于评分机制的web shell检测系统(英文)

针对及时检测攻击者利用系统漏洞或篡改网页开源代码秘密地在web服务器上嵌入的恶意代码web shell问题,提出了一种基于评分机制的web shell检测系统Evil-hunter.首先,从互联网和各种安全论坛上收集了大量的web shell经常使用的恶意函数样本数据.其次,根据恶意函数在web shell和正常web应用中的不同危险级别和使用频度,利用所提出的评分策略对所收集的样本数据进行评分,并分析统计结果以得出适当的分数阈值.最后,根据所得出的分数阈值,借用简单的检测算法来对web应用中所包含的恶意代码web shell进行识别.实验结果表明,与其他方法相比Evil-hunter具有更高的识别率和准确度.     

沈阳市雨水水质检测与分析(英文)

为了探讨雨水水质对雨水利用工程的影响,以沈阳市浑南新区的雨水水质为研究对象,对单体建筑屋面、小区径流及市政排出口的雨水进行为期一年的检测与分析.研究结果表明,影响雨水水质的主要污染物是COD和SS,特别是在降雨初期比较明显,随着降雨时间的延续,水质逐渐好转.市政排出口雨水COD和SS的含量最高,变化范围分别为167~249,119~332 mg/L,小区径流雨水COD和SS的变化范围分别为27~85和106~269 mg/L,建筑屋面雨水COD和SS的变化范围分别为15~80和50~153 mg/L.3个取样点的氨氮含量分别为1.7~5.2,3.7~18.2和5.2~25.6 mg/L.

Developing a comprehensive leadership development model in higher education context: A co-design approach

Higher education (HE) in the changing context requires leadership training and development as a vital element for university governance and innovation. While there are several theoretical frameworks on leadership development, most of them are outcome evaluation-oriented. Consequently, there is a lack of a leadership development model which emphasises both design process and expected outcomes. In addition to this, HE leadership development has been gradually transformed toward complexity and flexibility due to the volatile external environment of the 21st century. Thus, instead of having a development programme that simply focuses on individual skill enhancement, a comprehensive leadership development programme that equally fosters leaders' competencies (leader development) and develops collective leadership (leadership development) is increasingly utilised. Unfortunately, previous theoretical frameworks fail to take into consideration these new features. The main aim of this study was to develop a comprehensive theoretical model for academic leadership development (ALD) that promotes both leader development and leadership development. In the present study, 24 academic leaders, lecturers and researchers from five European and six Chinese HE institutions co-designed the ALD model. The constructed model consists of four main dimensions: theoretical core, types of training and providers, training format and ultimate goals. The results contribute to developing, promoting and enhancing leadership development in academic settings.
