Title Studies on security of industrial control network and its embedded devices
Abstract
In recent years, there are more cyber attacks against industrial control systems (ICS).The information security of ICS has become a hot topic.For ICS involving industry,energy, transportation, water conservancy, its security proplems deserve more concerns. This thesis starts from the architecture of ICS, its potential security threats are analyzed, some common security technologies are summarized, those practical applications of ICS security technologies,and the SCADA security services framework are introduced .Following these,one typical commercial security solution for ICS,Tofino system is introduced in detail.
The latter part of the thesis begins with the analysis of the vulnerabilities in the widely-used VxWorks embedded operating system.With the help of the virtual machine software VMware,the experimental platform of target VxWorks is built up.The penetration tests to the known vulnerabilities are lauched with the open-source tool Metasploit.
