"Organisations in India need to shift from a traditional vulnerability management approach to one that is risk-based"

Measures to be taken for Cyber threats  

Digital transformation and the work-from-home economy have converged and dramatically expanded the attack surface. To improve security in this expanded environment, organisations in India need to shift from a traditional vulnerability management approach to one that is risk-based. This will enable security teams to see and continuously assess the modern attack surface, predict which vulnerabilities pose the greatest business risk and act with confidence to effectively reduce risk. The ability to see, predict and act are foundational to stay ahead of cyber threats.

Best Practices

GPS is used by industries for critical navigation, control systems, and operational processes. This includes maritime, aviation, automotive, financial, telecommunications and defence industries. It serves as a mechanism to determine precise location and also as a critical, extremely accurate time reference.

GPS systems that are not properly secured are vulnerable to GPS jamming, spoofing, and cyberattacks. GPS location data should be monitored and benchmarked against other navigational data. In situations where extremely precise time is required, accurate backup time devices should be implemented. These two simple countermeasures will mitigate attacks against GPS navigation and time data or loss of signal. In addition, security teams require full visibility and real-time accounting of what is on the network – such as GPS time servers and protection devices to be able to detect and thwart threats. Cellular networks and many industrial processes use GPS for time synchronisation. Many operational technology (OT) plants have their own GPS receivers to run local instances of NTP (network time protocol). Time synchronisation is critical for industrial processes where certain functions must take place at precisely the right time for the operations to run properly. The best practice would be to use at least two of the four globally available satellite navigation-based time sources for redundancy. That way, if one source of time malfunctions, industrial plants can rely on the remaining sources for accurate time. In the event all GPS signals are disrupted, a high precision backup clock can be used.
