Audits in industrial wireless communications

Today, the wireless communication methods used in industrial environments for communication between the various devices that make up the industrial process are numerous and widespread. Among them are Wi-Fi, WiMAX and WirelessHART. From CERTSI a guide has already been published in which the characteristics and good security practices of these protocols were presented and analyzed.

Security audit of industrial wireless protocols
An industrial wireless communications audit is a process similar to a wireless security audit in corporate environments, in which the particularities of specific SCI environments and protocols must be taken into account. The main objective is to determine the security level of the wireless computing infrastructure of the client company; limited connection ethernet for this, different tests are carried out with the help of various applications with the aim of finding possible failures and / or weaknesses in the security of the wireless network. Care must be taken when conducting intrusion tests or vulnerability assessments, since they could compromise the security of the system, as well as the continuity of industrial processes.

Advantages of performing industrial wireless protocol audits
Industrial communication networks may be affected by various security problems and threats, some of them critical to the industrial process, such as a denial of service. That is why, performing security audits of these wireless networks will raise the state of communications security in a way that will allow:


  • Detect default settings.
  • Detect possible vulnerabilities of the devices.
  • Detect problems in controlling access to networks.
  • Detect errors in the implementation and deployment of networks in a way that identifies countermeasures to be applied for mitigation.
  • Reduce the impact of possible attacks and security incidents.
  • Implement corrective actions.
  • Check the version in use and its potential vulnerabilities

  1. PC designing is only somewhat more inside and out than simply assembling PCs. Some of it includes, Indian Dresses seeing how each part functions and how to make the parts converse with one another in various manners. Some of it includes programming to make PC parts converse with one another. Some of it includes framework structure, where you are really planning the PC itself - not selecting which segments, however composing what every guidance does and how every guidance is executed.
