【摘要】：隨著電力企業(yè)的快速發(fā)展,網(wǎng)絡信息技術的不斷更新,如何保障電力企業(yè)信息網(wǎng)絡安全穩(wěn)定運行,確保信息安全,已經成為影響電力企業(yè)安全生產的重大問題之一。網(wǎng)絡系統(tǒng)作為信息安全防護體系的基礎,網(wǎng)絡隔離的實現(xiàn)勢在必行! 本文介紹了信息安全的現(xiàn)狀,對杭州電力信息安全防護體系進行了調研,并進行了信息安全風險分析。提出了企業(yè)信息網(wǎng)絡安全的總體要求,明確了信息內、外網(wǎng)的定位和總體設計原則。通過對國內外多種網(wǎng)絡隔離技術的研究分析,從提高網(wǎng)絡可靠性、增強信息網(wǎng)絡安全性以及投資經濟性的角度出發(fā),對現(xiàn)有幾種比較流行的網(wǎng)絡隔離技術進行了研究比較,歸納了各自的優(yōu)缺點,給出了一個物理隔離與MPLS VPN技術隔離相結合的設計思路。結合企業(yè)信息網(wǎng)的現(xiàn)狀,開展企業(yè)信息網(wǎng)內外網(wǎng)網(wǎng)絡隔離方案的設計。確定了廣域網(wǎng)骨干鏈路采用MPLS VPN技術為主,城域網(wǎng)采用物理隔離為主的網(wǎng)絡隔離設計方案,并在杭州電力信息網(wǎng)改造升級工作中予以實現(xiàn)。設計方案安全可靠、科學合理,綜合考慮了企業(yè)信息網(wǎng)絡資源,充分利用了SDH傳輸鏈路、通信光纖鏈路、ADSL等通信通道資源,具有較高的經濟價值,適用于生產實際。隔離后的網(wǎng)絡系統(tǒng)為企業(yè)提供了堅強可靠的網(wǎng)絡環(huán)境,經受住了迎峰度夏和“兩會”安保的考驗,說明本文的工作成果在實踐中得以體現(xiàn)。
[Abstract]:With the rapid development of electric power enterprises and the continuous updating of network information technology, how to ensure the safe and stable operation of power enterprise information network and ensure information security has become one of the major problems affecting the safe production of electric power enterprises. Network system as the foundation of information security protection system, the realization of network isolation is imperative! This paper introduces the present situation of information security, investigates the information security protection system of Hangzhou electric power, and analyzes the risk of information security. This paper puts forward the general requirements of enterprise information network security, and clarifies the orientation and overall design principle of information inside and outside network. Through the research and analysis of many kinds of network isolation technologies at home and abroad, from the point of view of improving network reliability, enhancing information network security and investment economy, several popular network isolation technologies are studied and compared. The advantages and disadvantages of each are summarized, and a design idea of combining physical isolation and MPLS VPN isolation is given. According to the present situation of the enterprise information network, the design of the isolation scheme of the inside and outside network of the enterprise information network is carried out. In this paper, MPLS VPN technology is used as the main technology in the backbone link of WAN, and the design scheme of network isolation based on physical isolation is adopted in metropolitan area network, which is realized in the upgrading of Hangzhou Electric Power Information Network. The design scheme is safe and reliable, scientific and reasonable, considering the enterprise information network resources synthetically, making full use of the communication channel resources such as SDH transmission link, communication fiber link and so on. It has higher economic value and is suitable for production practice. The isolated network system provides a strong and reliable network environment for the enterprise, and withstands the test of meeting the peak in summer and the security of the "two sessions", which shows that the achievements of this paper can be reflected in practice.
