摘要

In big networks, security involves the authorization and authentication of data, which is controlled by the server. Firewall technology can be used so that the access to device can be only through one path which avoid unauthorized access but it may have limitation to block worms or Trojans. In such cases we can use antivirus to avoid unauthorized access. Chance may be also to attack the data or codes which are been transmitted from master to sensor nodes. Communication between sensor and master node can be secured using different encryption methods.Currently intrusion detection and intrusion prevention systems are often found in number of software application compulsory, but this is not the case in industrial control systems. It is very much difficult to detect and prevent software attacks such as denial of service, response injection, command injection, and reconnaissance attacks which are known attacks for serial port based industrial control systems. Mostly such attack damage the communication between remote devices and master terminal or human machine interface.
