Snort records the alerts to a log under/var/log/snort/snort.log.timestamp, where the timestamp is the point in time when Snort was started marked in Unix time. You can read the logs with the command underneath. Since you have only run Snort once, there is only one log, complete your...
这个模块是在JFreeChart包的基础上开发的Chart.jsp中实现生成饼状图的关键代码如下: DefaultPieDataset data new DefaultPieDataset ; LogDAO logDAO LogDAOFactory.getLogDAOInstance ; int totalCount logDAO.findAllCount ;//攻击总数 List list logDAO.findAllLog ; Log log null; int icmpCount 0; int udp...
图1规则树的层次结构图 Fig.IHierarchystructureofruletree Snort初始化并解析规则时,首先根据Snort规则头部中的5种操作规~JJ(alert,log,pass,activate, dynamic)生成了5条规则链表,每条链表节点又通过ListHead结构类型的RuleList指针指向下面的各子规则链表,子规则链表为根据Snort规则头部中的协议划分的TCP,UDP,ICMP,...
–Input: Dataset D and initial estimates –Output: Clustered set of Data Points –EM Algorithm has two steps: • Expectation Step: Finds the expected value of complete data log likelihood • Maximization Step: Maximizes the expectations computed in ...
a significant problem facing current IDS technology now is the high level of false alarms. The main purpose of this paper is to investigate the extent of false alarms problem in Snort, using the 1999 DARPA IDS evaluation dataset. A thorough investigation has been carried out to assess the accu...
