The reliable operation of the electric power systems (EPSs) depends on the quality of data provided by SCADA and WAMS, which are part of the information and communication infrastructure of cyber-physical EPS. Increasing threats to cyber security of EPS indicate the need to develop data analysis methods capable to take into account the effects of cyberattacks on systems for collecting, transmitting and processing the information. The findings of the studies have shown the impact of cyberattacks on the quality of data. The interdependence between the violation of cybersecurity properties and the low quality of data is revealed. The paper proposes an algorithm for quality assessment of SCADA and WAMS data, taking into account the cybersecurity properties of information and communication infrastructure of EPS
