Why Is Critical Infrastructure Protection (CIP) Important?

Securing critical infrastructure is vital to ensuring the American people have access to services like drinking water, electricity, and food. It is also crucial to protecting high-value industries from cyberattacks, such as the chemical, communications, emergency services, healthcare, information technology, and transportation sectors. 

If hackers could breach the critical infrastructure of the sectors listed above, the result could have devastating consequences for organizations. It could also pose a serious threat to global economies and communities. Therefore, successfully protecting critical infrastructures requires government agencies to establish strong partnerships with commercial parties and use appropriate solutions to implement and manage the initiatives.

Protecting critical infrastructure is also reliant on recognizing the risks that could threaten their integrity. This includes attack vectors and network security, as well as issues like equipment failing, the risk of human error, and natural disasters such as weather activity. These risks must be factored into any decision around solutions that enable organizations to detect and identify security attacks and network behavior anomalies. 

Top 10 CIP Technologies For Enterprises

Many of the critical infrastructure protection examples discussed above use the following enterprise technologies:

1. Deep CDR: Content disarm and reconstruction (CDR) disassembles a file into its constituent parts and eliminates any potential threats.
2. Proactive DLP: Data loss prevention technology (DLP) protects sensitive information via metadata removal, automatic document redaction, or watermark addition rather than blocking files.
3. Multiscanning: Multiscanning technology makes anti-malware solutions resilient and significantly enhances malware detection rates and outbreak detection times.
4. File-based vulnerability: This technology searches for flaws in files and applications before they are installed, so IT teams can fix any vulnerabilities.
5. Threat intelligence: To avoid malware outbreaks or stop them, threat intelligence analyzes malicious patterns, making it easier to identify threats.
6. Sandbox: Sandboxes run untested code and third-party software in an environment that has no access to the company’s network. They can also be used to contain threats in a safe, insulated environment, enabling you to observe how they behave.
7. Endpoint compliance: This enables enterprises to identify, evaluate, and correct applications that do not adhere to established operational and security regulations.
8. Endpoint vulnerability assessment: This ensures that all programs are running with the most recent versions, strengthening endpoint security. Automatic patching can quickly fix vulnerabilities after they have been found.
9. Malware detection on endpoints: This evaluates an endpoint for any suspicious activity by checking the libraries and processes that are running.
10. Endpoint application removal: This enables the removal of security solutions, including antivirus software and firewalls, that are not appropriate or approved for the work environment. It can remove potentially unwanted applications (PUA) as well.

How Do We Protect And Manage Risks to Critical Infrastructure?

The responsibility for protecting critical infrastructures lies with the Cybersecurity and Infrastructure Security Agency (CISA), a DHS agency that Congress created in November 2018. The agency leads the coordinated national effort to protect critical infrastructure, with three key aims:

Managing the risk faced by critical infrastructure

Critical infrastructure risk is managed by the National Risk Management Center (NRMC), which is an entity within CISA. NRMC aims to identify and address the biggest risks that the U.S.’s critical infrastructure faces through analysis, planning, and collaboration. It does this by identifying and prioritizing the most significant risks that critical infrastructure faces and taking actions that will mitigate the risks.

Enhancing the security of critical infrastructure

Improving security is fundamental to protecting critical infrastructure. This includes enhancing physical security, such as ensuring doors are locked and placing effective fences to protect buildings. It also includes deploying effective cybersecurity solutions to protect organizations’ networks, systems, and users, as well as identifying and addressing their virtual vulnerabilities. Organizations also must practice good cyber hygiene by preventing the use of weak passwords, patching vulnerabilities, and avoiding phishing scams and malware attacks.

However, critical infrastructures present significant cybersecurity challenges. For example, ICS cannot be scanned for vulnerabilities in the same way as virtual IT environments because doing so can take the industrial system offline, which could bring down a plant’s operations. Additionally, many OT systems have existed since before the internet and were in “air-gapped” systems that lowered their risk of cyberattacks. But with the world becoming increasingly connected, these systems are becoming more exposed to hackers’ exploits.

Enhancing the resilience of critical infrastructure

Critical infrastructure needs to be resilient to changing conditions, as well as withstand and recover from disruption. This means strength against physical and cyber threats, which require a comprehensive cybersecurity defense program. 

The National Institute of Standards and Technology (NIST) assists organizations in this. It enables them to develop and implement effective protection to their critical infrastructure. DHS also provides the Cyber Resilience Review (CRR), which is a free resource that offers insight into organizations’ cyber resilience status. The CRR also includes a NIST framework crosswalk, which enables organizations to align their processes with the NIST program.

Advantages

Critical infrastructure security offers a wide range of benefits that directly affect our daily lives and the overall health of society.

Enhanced Public Safety: Strong security measures for critical infrastructure like power grids and water treatment plants help prevent disruptions that could endanger public safety. A cyberattack causing a blackout, for instance, could disrupt essential services like hospitals and communication networks.
