【摘要】 随着网络技术和网络打印机的不断发展,人们在通过网络打印获得极大方便的同时,也面临着更为严峻的安全问题。本文通过对网络打印机安全这一空白领域进行研究,旨在通过分析网络打印机存在的安全漏洞和容易受到的各类攻击,设计一个网络打印安全系统,解决现有网络打印机存在的不安全问题。本文首先分析了当前大多数网络打印机存在的安全漏洞;针对这些漏洞,通过对当前实现网络安全的几种技术进行比较和分析,提出了一种解决现有网络打印机安全问题的实现方案,设计了一个网络打印安全系统。系统通过对网络打印数据包加解密传输来增强网络打印机数据的传输安全,通过嵌入式防火墙提高网络打印机的抗攻击能力。在此基础上通过使用Netfilter技术实现了网络打印机打印数据包的捕获,通过使用iptables规则实现了嵌入式防火墙功能,完成了嵌入式平台中数据捕获解密和防火墙模块的软件设计。经过测试,平台有效的增强了网络打印数据的传输安全,提高了网络打印机本身的抗攻击能力。
【Abstract】 With the development of the network technology and network printer, through the network printing people obtain great convenience, but also faced with more severe security problems. The paper focuses on the domain of network printer security which is still a blank fileld. Through the analysis of network printer security loophole the paper designs a network printing security system to solve the unsafe problems of the existing network printer.The paper firstly analyzes the security vulnerabilities of network printers.In view of these vulnerabilities, with the comparison of several network security technologies, the paper proposes a strategy to solve the network printer security problems and designs a network printing security system. The system encrypts the network printing packet to enhance the security of network printing transmission; embedded firewall is utilized to improve the anti-attack capability of the network printer. Base on these technologies the paper designs and implements the embedded platform of the system. In the embedded platform, Netfilter technology is utilized to achieve the capture of network printing packet, the embedded firewall is implemented by the usage of iptables rules.By testing the platform, the result indicated that the embedded platform has enhanced the network printing transmission security and improved the network printer’s anti-attack capability effectively.
