Is Your City’s Power Grid Vulnerable to Cyber Attacks?
Cyber security is a paramount element for safeguarding critical infrastructure. These systems and networks are considered vital because their malfunction or failure could have devastating effects on national and economic security, public health, and safety.
In the United States, critical infrastructure refers to organizational and physical structures and facilities which are so crucial to the country’s economy, society, and security that their destruction or malfunction would have a severe repercussion. These sectors include energy, healthcare, transportation, financial services and more.
Organizations who need to protect critical infrastructure must use the NIST framework for critical infrastructure protection and create a plan to enhance their cybersecurity. They also need to practice good cyber hygiene, such as abstaining from weak passwords and patching vulnerabilities as quickly as possible.
Organizations increasingly rely on information technology to run their operations. These tools permit companies to manage resources, communicate with customers, and conduct business transactions; however, these systems could pose a security risk if hackers gain access to critical infrastructure.
Hackers have been known to target nuclear power plants that provide electricity to millions of Americans. Unfortunately, these attacks are becoming increasingly frequent.
One of the most serious attacks was the Equifax breach that affected 143 million people. This incident serves as yet another reminder of how cyber attackers can exploit critical infrastructure for extortion and financial gain.
Cybersecurity for critical infrastructure is a complex and multi-faceted issue that necessitates experts in each field. This makes it difficult to accurately reflect risk exposure or detect the consequences of a cyberattack. To accurately assess risk and minimize potential damage caused by a cyberattack, cybersecurity specialists need to expand their skillsets and collaborate with teams responsible for critical infrastructure. Doing this will give them an integrated view of vulnerabilities, issue severity, and potential outcomes.

Is Our Energy Infrastructure Vulnerable to Cyber Attacks?
The energy sector is an attractive target for nation-state and for-profit cybercriminals due to its highly distributed nature and complex infrastructure, coupled with a late adoption rate of digital transformation technologies. As such, energy cybercrimes tend to focus on smaller targets within this highly distributed environment.
Electric-power and gas industries are particularly vulnerable to cyber attacks due to their dispersed geographic locations, intricate third-party supply chain relationships and interdependencies between OT infrastructure and IT networks. This leaves companies vulnerable to exploitative activities like billing fraud with wireless “smart meters,” commandeering operational technology systems to stop multiple wind turbines or physical destruction.
Fortunately, utilities can take steps to combat these threats and increase their resilience against cyber incidents. These include taking a strategic, holistic approach to security and risk management; developing cyber resilience policies; as well as continuous monitoring and evaluation.
Policy makers, regulators and utilities must guarantee that designated organisations consistently conduct system-level risk analyses to identify key threats scenarios and vulnerabilities. They also need to assign security measures according to the level of system risk.
Utilities and operators should create risk-based cyber security plans that identify which assets are critical, the specific security measures required for those assets, as well as processes and procedures to protect them. Furthermore, they must train employees on awareness of and response to cyber threats.
Utility cybersecurity programs have become a top priority among both private and public utilities, despite the challenges presented. Many utilities are banding together through industry groups like the Electricity Subsector Coordinating Council to coordinate information about cybersecurity threats, respond to attacks, and recover from them. This cross-utility collaboration is an effective way to boost security preparedness while reducing risks.

Is Your City’s Transportation System Vulnerable to Cyber Attacks?
The transportation sector plays an integral role in our economy and daily lives, connecting people and cargo across regions as well as between countries. Unfortunately, it also serves as a target for malicious hackers who aim to take advantage of security flaws in order to make financial gain from exploiting vulnerabilities.
With the rise of technology and the Internet of Things (IoT), transportation companies are more vulnerable than ever before to cyber attacks. With more devices connected to the internet and fewer security measures in place, these threats have become both more serious and frequent.
Cybersecurity threats to the transportation sector include ransomware and data breaches. These issues can have devastating effects on operational, financial, and reputational outcomes.
Many transportation companies utilize the most up-to-date technology in an effort to boost efficiency and enhance customer service. Unfortunately, these advancements could also expose them to new types of malware that could be employed for extortion, business disruption, or theft of valuable intellectual property.
Cybercriminals often target unprotected systems, making them susceptible to hacking. A recent example involves the theft of confidential information from San Francisco and Atlanta departments of transportation.
TC’s cybersecurity policy aims to safeguard vehicles against attacks and keep Canadian jurisdictions prepared for emerging technologies like connected and automated vehicles (CAVs). Goal 1 of the policy calls for incorporation of vehicle cyber security considerations into policy and regulatory frameworks.
Given the myriad of challenges presented by CAVs and their supporting infrastructure, TC has collaborated with industry partners to create a coordinated approach for vehicle cyber security. This allows policy and regulations to remain flexible enough to accommodate rapid technological progress while still satisfying stakeholders’ concerns.

Is Your Healthcare Data Safe from Cyber Threats?
Healthcare is an especially vulnerable sector to cyber threats. With many specialized hospital information systems, numerous connected medical devices and various third parties with access to sensitive patient data and essential assets, the healthcare sector presents a tempting target for malicious actors.
Cybersecurity in the healthcare industry is a complex challenge that necessitates an integrated strategy to safeguard both business continuity and patient safety. To guarantee successful cybersecurity operations across healthcare organizations, IT vendors, medical device manufacturers, and government agencies that make up this sector must all take a shared responsibility.
Despite the difficulties experienced in this industry, many healthcare organizations are making progress when it comes to cybersecurity. The passage of HITECH Act in 2009, for instance, has spurred healthcare organizations to invest in new technologies and enhance their security postures.
However, the growing use of e-health, telemedicine and remote patient monitoring has exposed healthcare organizations to cyberattacks that can do significant damage. For example, a recent attack on a hospital in Colorado cancelled services and prevented doctors from accessing cash registers, email or fax machines.
The healthcare sector is an attractive target for criminals due to its vast attack surface and lucrative financial rewards. A significant proportion of attacks within this industry are ransomware attacks, with an increasing number of cybercriminals targeting medical devices and records.
Healthcare organizations must also implement policies that restrict unauthorized access, such as two-factor authentication and complex password requirements.
Cybersecurity is especially critical in the healthcare industry due to its reliance on confidential patient data and often outdated systems. A compromised system could leave an organization vulnerable to financial penalties, loss of customer trust, even bankruptcy. For this reason, healthcare organizations must prioritize cybersecurity and hire staff solely dedicated to maintaining online safety.
