Introduction

Cybersecurity threats are multifaceted, targeting various layers of information systems—from physical infrastructures to web applications. Understanding these threats requires a detailed examination of their resources, vulnerabilities, and potential mitigations. This paper explores five significant threats spanning different categories including physical security, Identity and Access Management (IAM), Internet of Things (IoT), web applications, and network security. For each threat, I analyze its nature, why it is interesting, involved vulnerabilities, associated incidents, and suggested countermeasures.

Threat 1: Physical Security Breach - Unauthorized Access to Data Centers

Resources used for research include reports from the U.S. Department of Homeland Security, Cisco's security whitepapers, and scholarly articles on physical security vulnerabilities.

This threat involves unauthorized physical access to critical infrastructure such as data centers and server rooms. It falls under the physical security topic, emphasizing the importance of safeguarding hardware against intrusion, theft, or sabotage.

It is particularly interesting because physical breaches often serve as the initial step for more complex cyber-attacks. Attackers might forcibly enter a data center, bypass security controls, and gain direct access to servers and network equipment.

The core vulnerability involves weak physical access controls, such as inadequate surveillance, poor security personnel procedures, or lack of biometric authentication. These vulnerabilities can be exploited by intruders or insiders with malicious intent.

The CVSS (Common Vulnerability Scoring System) score for physical security breaches typically ranges from 4.0 to 8.0, depending on the ease of access and potential impact. In this case, a score of 7.5 is justified because it signifies high impact and exploitability due to the potential for severe data theft or destruction.

A notable incident is the 2013 breach of the Iranian nuclear facility, where physical intrusion led to operational disruptions. Such incidents underline the potential catastrophic consequences of physical breaches, impacting the CIA triad by compromising confidentiality, integrity, and availability.

Mitigations include implementing stringent access controls, surveillance systems, biometric authentication, and employee training to recognize and deter unauthorized efforts.

Threat 2: IAM Vulnerability - Credential Stuffing Attacks

Sources include OWASP reports, research papers on account hijacking, and security blogs analyzing credential stuffing incidents.

This threat pertains to IAM, focusing on the exploitation of weak or reused credentials across multiple platforms. Credential stuffing involves automated login attempts using leaked username-password pairs, aiming to compromise user accounts.

It is interesting because it highlights how human factors—such as password reuse—combined with automation technologies, can lead to widespread account compromises with relatively low effort.

The main vulnerability involves poor password management and lack of multi-factor authentication (MFA). Attackers leverage vast databases of stolen credentials to infiltrate systems that do not enforce strong access controls.

The CVSS score for credential stuffing varies but often ranges around 6.0 due to the ease of automation and substantial impact when compromised accounts carry sensitive information.

An example incident is the 2019 Capitec Bank breach in South Africa, where credential stuffing led to unauthorized transactions and financial losses. Impact on CIA included confidentiality breaches and potential financial fraud.

Mitigation strategies involve enforcing strong password policies, deploying MFA, monitoring login activities for anomalies, and educating users on credential security.

Threat 3: IoT Device Exploitation - Botnet Formation

Research includes IoT security advisories from Symantec, industry reports, and academic papers on IoT vulnerabilities.

This threat concerns IoT devices, which are often poorly secured, making them prime targets for exploitation. Attackers compromise connected devices and incorporate them into botnets for large-scale attacks, such as Distributed Denial of Service (DDoS).

Interesting because of the rapid growth of IoT within critical domains—such as smart homes, healthcare, and industrial environments—combined with the persistence of insecure default configurations.

The vulnerability involves weak or hardcoded passwords, lack of firmware updates, and insecure communication protocols, which attackers exploit to take control of devices.

The CVSS score for IoT exploitation varies; in the case of Mirai botnet—one of the most infamous examples—a score of 9.0 is assigned due to the high impact and ease of exploitation.

The Mirai botnet incident in 2016 resulted in massive DDoS attacks disrupting major websites like Twitter and Reddit, demonstrating catastrophic impacts on availability. The attack compromised CIA's availability aspect severely.

Response measures include securing default passwords, regular firmware updates, network segmentation, and monitoring for unusual device activity.

Threat 4: Web Application - SQL Injection Attacks

Sources comprised of OWASP top vulnerabilities, academic research on database injection, and real-world breach reports from cyber incident records.

This threat involves malicious input to web applications that results in unauthorized querying or modification of databases. SQL Injection (SQLi) is a prevalent attack vector targeting web apps.

It is interesting because of its simplicity and devastating impact—attackers can bypass authentication, extract sensitive data, or corrupt systems with minimal technical hurdles.

The vulnerability involves unsanitized input fields that are directly embedded into SQL queries, enabling attackers to manipulate queries maliciously.

The CVSS score for SQL Injection is often classified as 9.0 due to its high exploitability and potential to lead to complete data exfiltration and system compromise.

The 2017 Equifax breach exemplifies this threat—attackers exploited SQLi vulnerabilities to access millions of personal records, severely impacting confidentiality and trust.

Countermeasures include parameterized queries, input validation, web application firewalls, and regular security testing.

Threat 5: Network Eavesdropping and Man-in-the-Middle Attacks

Research involves network security textbooks, recent case studies, and standards on secure communications.

This threat affects network security by intercepting or altering data in transit between systems. Attackers position themselves between communicating parties—using intercepting or impersonation techniques.

What makes this interesting is its ability to compromise confidentiality without directly attacking end devices, simply by exploiting insecure communication channels.

The vulnerability stems from unencrypted data transmission or weak encryption protocols, which attackers exploit to intercept sensitive information or inject malicious data.

CVSS scores can reach 8.0 for these attacks, especially when sensitive data—like passwords or financial information—is exposed or manipulated.

The 2013 Target data breach involved network eavesdropping and malware installed via compromised communications, resulting in a significant impact on consumer confidentiality and trust.

Mitigations include deploying end-to-end encryption, using VPNs, enforcing strong encryption standards, and monitoring network traffic for anomalies.

Conclusion

Understanding diverse cybersecurity threats across physical, technical, and application domains is critical for developing effective defense mechanisms. Physical security breaches remind us that physical integrity supports overall cybersecurity. IAM vulnerabilities demonstrate how human and technical factors combine to create significant risks. IoT device exploitation and botnet formation call for rigorous device management practices, while web application threats highlight the importance of secure coding and input validation. Network eavesdropping underscores the necessity of robust encryption and traffic monitoring. Combining technological safeguards with policy and awareness initiatives forms a comprehensive approach to mitigate these evolving threats, safeguarding the CIA triad effectively.
