This defense in depth discussion scenario is an intentional cybersecurity attack on the water utility’s SCADA system. It occurs during the fall after a dry summer in Fringe City. The water utility’s Information Technology (IT) person did not receive an expected pay raise and decides to reprogram the SCADA system to shut off the high-lift pumps. The operator’s familiarity with the SCADA system allows him to reprogram the alarms that typically notify operators of a high-lift pump failure. In addition, he prevents access to the SCADA system by others. A wildfire breaks out on the outskirts of the city. Please identify what type(s) of new countermeasures should have been implemented to prevent this cyber attack from occurring. Start a discussion thread and discuss what type(s) of new countermeasures should have been implemented to prevent the cyber attack described above from occurring. Be specific in recommending countermeasures for this scenario. You must do this following: 1) Create a new thread. As indicated above, Purchase the answer to view it

New Countermeasures to Prevent Cyber Attacks on a Water Utility’s SCADA System

In order to prevent the cyber attack described in the scenario, a number of new countermeasures should have been implemented. It is clear that the operator’s familiarity with the SCADA system and his ability to reprogram the alarms and prevent access to the system played a key role in the success of the attack. Therefore, the countermeasures should focus on addressing these vulnerabilities. Here are some specific recommendations:

1. Role-based access control: Implementing role-based access control (RBAC) would help prevent unauthorized access to the SCADA system. The system should be configured to only allow specific roles, such as operators or administrators, to access and modify critical settings. This would limit the ability of an individual with malicious intent, like the IT person in this scenario, to make unauthorized changes.

2. Two-factor authentication: Implementing two-factor authentication (2FA) would add an additional layer of security to the SCADA system. This would require users to provide a second form of authentication, such as a token or a biometric scan, in addition to their username and password. Even if an attacker were to gain access to someone’s login credentials, they would still be unable to authenticate without the second factor.

3. Intrusion detection system: Installing an intrusion detection system (IDS) would help detect and alert the water utility to any suspicious activity on the SCADA system. The IDS should be configured to monitor for any unexpected changes to system settings or attempts to tamper with alarms or access controls. This would allow for early detection of any unauthorized modifications and enable a prompt response.

4. System log monitoring and analysis: Implementing a system log monitoring and analysis solution would provide the ability to review and analyze system logs for any unusual or suspicious activity. This would help in identifying any anomalies that may indicate a potential cyber attack, such as repeated login attempts, unusual login times, or access to sensitive system settings. Regular review and analysis of these logs would enable the water utility to take timely action to prevent a cyber attack.

5. Regular security awareness training: Conducting regular security awareness training sessions for all personnel with access to the SCADA system is crucial. This training should cover topics such as recognizing social engineering attacks, the importance of strong passwords, and the potential impact of a cyber attack on the water utility. Increasing the level of security awareness among staff can help prevent insider threats and ensure that everyone understands their role in maintaining the security of the SCADA system.

By implementing these countermeasures, the water utility can significantly improve the security posture of their SCADA system and reduce the likelihood of a cyber attack like the one described in the scenario. However, it is important to note that effective cybersecurity is an ongoing process and requires regular monitoring, updates, and adaptation to address emerging threats.
