6 FAQs about [Attack countermeasure strategies in power grid system]
How to prevent stealth attack on power grid control system?
To prevent a stealth attack on a power grid control system, it is essential to have appropriate security management in addition to using security strategies. This includes security policies, strategies, and programs based on accurate threat and risk analysis.
How to protect a smart grid from cyberattacks?
This approach is crucial in protecting the smart grid from cyberattacks by facilitating self-healing mechanisms, such as the reconnection of Phasor Measurement Units (PMUs) and the restoration of system observability . In Fig. 13, we can observe the self-healing process of a smart grid, where it undergoes several steps.
How do we deter deliberate attacks on the power grid?
The analysis focuses on two strategies for deterring deliberate attacks on the power grid: denial and cost imposition. For deterrence by denial, the report focuses on "outside-the-fence" interventions—ways in which DoD can engage with entities or infrastructure not owned by DoD.
Are smart grid systems vulnerable to trespassing?
Critical vulnerabilities have been identified, as discussed in Refs. [33,34]. Physical security emerges as a primary vulnerability. Unlike conventional power systems, the smart grid network includes numerous components located outside the utility's premises, exposing them to physical trespassing risks.
How can smart grids mitigate DoS attacks?
To address the challenge of mitigating Denial of Service (DoS) attacks in smart grids, a multifaceted approach integrating various techniques is essential, as highlighted in Ref. . Specifically, no single solution exists for DoS mitigation, necessitating the integration of multiple techniques.
How do attackers manipulate meter measurements?
Attackers can manipulate meter measurements in a smart power grid by either locally compromising meters or falsifying data packets that are sent to the control centre by exploiting the plaintext transmission protocol. Altering the control centre database is another method used by attackers.
