中文摘要
資訊與網路技術發展迅速,物聯網趨勢將產生更多智慧化應用商機的崛起, 從日常家庭個人到工業自動化,以及城建交通到軍事防恐等。預計 2020 年市面上 將有 500 億物聯網設備連接到網際網路,根據調查研究,目前仍有 70%物聯網設 備存在著安全性問題。開放一個服務通訊埠就是一個入侵通道,而最容易遭受攻 擊的服務通訊埠以 Telnet 居冠,在日益嚴重的危害下,需要積極收集更多攻擊資 訊。
誘捕系統可以欺騙駭客試圖獲得未經授權的系統訪問權限,並研究駭客們與 弱系統之間的互動,有助於了解目前最新攻擊策略。為了服務簡易性以及維護方 便性,大多數的雲端服務平台使用虛擬化技術作為服務架構基礎。強大的日誌分 析平台來專門收集和處理不同資料來源的資料,並提供一組資料分析的工具。
因此,本研究運用這些開放原始碼軟體建置一套高互動型誘捕系統,它可針 對目前正在運作的服務通訊埠做監測,利用設置的誘捕系統所擷取到的資料,以 分析來自駭客的相關資訊。
實驗環境歷經 2 個月的運作,總共收集約 146,440 筆 session 活動紀錄、126 個來源國家、73 組登入嘗試帳號、284 組登入嘗試密碼,以及 2,655 筆指令操作紀 錄。分析系統利用 Cowrie 收集的活動紀錄資料,經過資料清洗,Logstash 對資料 類別進行過濾及分類,依不同的分類輸出至 Elasticsearch 資料庫,最後由 Kibana 設定資料搜尋條件及呈現圖表樣式,以協助資訊安全人員、網路管理者等資料收 集的負擔及分析惡意程式或惡意指令參考之依據。
Abstract
Because the development of information technology and network technology advanced very quickly in recent years, the IoT development will generate more intelligent application and business opportunities, e.g. family life, industrial automation, transportation and military. It is estimated that the world will see 50 billion IoT devices by 2020 to connect Internet. A recent study showed that 70 percent of IoT devices contain serious security problems. When you enable a service port, it means you enable an intrusion channel. And the most vulnerable service port is Telnet service. More and more the IoT security issues, it needs to collect more attack information actively.
A honeypot can deceive attackers trying to gain unauthorized access to a system. And studying their interactions with vulnerable networks helps better understand their tactics. For the simple service and effective maintenance, most of the cloud service platforms usually adopt virtualization technology to construct the infrastructure of the platforms. A powerful log analysis platform that collects and processes data from multiple data sources, and that provides a set of tools to analyze the data.
Therefore, in this paper is totally based on open source software to deploy the high-interaction honeypots environment, it can monitor the service port number currently for running, and try to collect data by the honeypots, then analyze more information motivation from attackers.
iv
After 2 months of operation, we collected a total of about 146,440 session activity records, 126 source countries, 73 user accounts, 284 user passwords, and 2,655 command operation records. The analysis system using the Cowrie to get data, and reads the cleaned data via Logstash. Combine Logstash to filter the data category. Export to the Elasticsearch database and index it. Finally, Kibana shows the results of the analysis. It could help engineers to burden of data collect and easy to analysis data of malicious programs or malicious commands.
