中文简介:
目前, 针对恶意软件最重要的防御措施是防病毒产品, 这些产品侧重于从白名单中验证有效软件, 阻止黑名单中的无效软件, 以及在控制的方式。灰色列表包含未知的软件程序, 可能是正常的或恶意的, 通常由病毒分析人员进行身份验证或手动拒绝。不幸的是, 随着恶意软件编写技术的发展, 需要病毒分析师每天分析的灰色列表中的文件样本数量也在不断增加。本文利用不同的特征表示, 利用不同的特征表示, 利用不同的特征表示, 利用不同的特征表示, 利用不同的特征表示, 利用不同的特征表示, 从灰色列表中开发了一个用于恶意软件检测的智能文件评分系统 (简称 ifss)。动态训练集。据我们所知, 这是首次将这种集成方法应用于恶意软件检测。ifss 使病毒分析师能够从巨大的灰色列表中识别恶意软件样本, 并提高了防病毒软件的检测能力。它已经被纳入金山词霸的防病毒软件的扫描工具。对大量和真实的灰色列表每日收集的案例研究表明, 我们的 ifss 系统的检测能力和效率优于其他流行的扫描工具, 如 nod32 和卡巴斯基。
课程简介: Currently, the most significant line of defense against malware is anti-virus products which focus on authenticating valid software from a white list, blocking invalid software from a black list, and running any unknown software (i.e., the gray list) in a controlled manner. The gray list, containing unknown software programs which could be either normal or malicious, is usually authenticated or rejected manually by virus analysts. Unfortunately, along with the development of the malware writing techniques, the number of file samples in the gray list that need to be analyzed by virus analysts on a daily basis is constantly increasing. In this paper, we develop an intelligent file scoring system (IFSS for short) for malware detection from the gray list by an ensemble of heterogeneous base-level classifiers derived by different learning methods, using different feature representations on dynamic training sets. To the best of our knowledge, this is the first work of applying such ensemble methods for malware detection. IFSS makes it practical for virus analysts to identify malware samples from the huge gray list and improves the detection ability of anti-virus software. It has already been incorporated into the scanning tool of Kingsoft's Anti-Virus software. The case studies on large and real daily collection of the gray list illustrate that the detection ability and efficiency of our IFSS system outperforms other popular scanning tools such as NOD32 and Kaspersky.
