In an effort to help government departments and agencies to mitigate the risk of being affected by ransomware attacks, the Department of Public Service and Administration (DPSA) recently issued a circular with action-orientation cybersecurity strategies.

The Department’s Director-General, Ms Yoliswa Makhasi said in the recent past months, cybersecurity incidents have been on the rise with ransomware attacks against government departments that caused significant service delivery interruptions, and bringing service delivery at service points to a standstill. 

“The purpose of the circular is to provide the necessary measures that departments must urgently implement to mitigate the risks associated with the continuous cybersecurity attacks to public sector institutions.

“These attacks pose significant risk to the ongoing operations of government and ultimately to government’s ability to protect its data and deliver services.

“Those that seek to exploit the vulnerabilities within government Information Technology (IT) systems will surely be looking at the recent cyber security incidents with a view of expanding their nefarious activities. It is therefore, imperative that government responds quickly and in a coordinated manner to secure its IT systems and data,” said DG Makhasi.
