| Abstract: |
| After the outbreak of Stuxnet, Industrial Control System (ICS) began to become one of the targets of attack. With the continuous understanding of the industrial control system, attackers are more sophisticated, using complex means and more advanced technology, to launch various attack. As an important basic control equipment in industrial control system, PLC (Programmable Logic Controller) information security issues are worthy of attention. From the perspective of both the attacker and defender, the paper first analyzes the basic architecture and working principle of the PLC and points out its vulnerabilities, then classifies the PLC attack, and analyzes the attack principle of all kinds of attack technology thoroughly; it gives a general summary of PLC information security research progress at home and abroad. Finally, future research trend and prospects for PLC information security are presented. |
