Addressing Emerging Cybersecurity Challenges

Cybersecurity in the current technological context highlights the evolution and emerging challenges, enhancing the importance of AI (Artificial Intelligence) and ML (Machine Learning) in detecting and preventing threats, emphasizing both the opportunities and associated risks to these technologies. The expansion of the Internet of Things (IoT) expands the attack surface, requiring a more comprehensive security approach, such as adopting the Zero Trust model, which assumes no trust by default and requires rigorous and holistic verification. Envisions a gradual transition to passwordless authentication methods, such as biometrics, based on “something I am” Multi-Factor Authentication (MFA), to overcome the vulnerabilities of traditional 1-Factor “something I know” passwords or second Factor “something I own”. Warns of the risks of the post-quantum era and what could pressure the evolution of even stronger encryption algorithms. Addresses concerns about ransomware 2.0, which employs more sophisticated social engineering tactics for dual extortion and data theft. Furthermore, it highlights the need to protect privacy and personal data in an increasingly interconnected world, where sensitive information is vulnerable to information disclosures, or breaches and cyber-attacks.

It also draws attention to the impact of geopolitical conflicts on cybersecurity, exemplified by tensions between Israel and Hamas and the Ukraine-Russia conflict, which can influence cybersecurity globally.

Artificial Intelligence and Machine Learning

Artificial intelligence is playing a crucial role in detecting and preventing cyber threats. Through predictive analytics and machine learning, security systems can identify suspicious behavior patterns in real time, learning from past interactions to predict and neutralize future threats. This ability to adapt and continuously learn strengthens defenses against increasingly powerful attacks. And this same technology is also being used to create more sophisticated attacks, requiring a careful approach to harness the benefits without increasing vulnerability (TechTarget, 2024; ISACA, 2024).

AI: A Double-Edged Sword

AI promises to revolutionize cyber defenses with threat detection systems capable of analyzing vast amounts of data. However, the same technology also empowers cybercriminals to enhance their attacks. Despite the potential for using AI in social engineering, traditional methods continue to predominate due to their effectiveness. But at the level of Generative AI, several applications using LLM Large Language Models improve this work, and are proliferating every day. Examples are: WormGPT, FraudGPT, WolfGPT, EvilGPT, PoisonGPT, DarkBERT, DarkBard (GROUP-IB, 2024). Also a word about voice and video deepfake technologies, which perfectly emulate humans that, either in VoiP (Voice over IP) or Videoconferencing, are flawlessly imitated in sophisticated attacks.

The ethical question of AI

The increasing adoption of AI brings unique challenges. For example, AI, while essential in detecting threats, brings ethical and governance concerns, as well as vulnerabilities that attackers can exploit. Managing an avalanche of data generated by AI is another critical challenge, as is the presence of unauthorized AI, known as "shadow AI", within organizations. In this regard, through the recent “AI Act” legislation, the European Union aims to increase trust in AI by strengthening rules around data quality, transparency, human oversight and accountability, by classifying AI systems for the risk they present, and the requirements for its development and use, including the prohibition of biometric surveillance and the mandatory requirement that Generative AI systems must disclose AI-generated content.

?

The Expansion of IoT

Furthermore, the expansion of IoT (Internet of Things) presents new challenges, expanding the attack surface of organizations, requiring a more comprehensive security approach, demanding robust strategies that go beyond the protection of central systems. The principle of Zero-Trust, which denies trust by default and verifies everything and always, is a vital emerging strategy in information security. With the proliferation of network-connected devices, from smartphones to industrial devices, the variety and complexity of vulnerabilities increases exponentially. This requires a more comprehensive security approach that is not just limited to protecting core systems but also encompasses the security of IoT edge devices (ISACA, 2024).

?

Towards a Passwordless Future

A movement towards authentication without passwords (Passwordless) is anticipated, discussing the implementation of more secure authentication methods, such as biometrics and unique access codes (OTP One Time Passwords), to overcome the vulnerabilities inherent to traditional Passwords. The persistence and evolution of Passwords stands out as a surprisingly durable aspect of digital security. Despite predictions of their decline, passwords remain prevalent due to their usefulness, ease of use and change. However, there is an expectation of an increase in the adoption of more secure authentication methods, such as biometrics, which offer a more robust alternative without compromising usability (Security Intelligence, 2023).

?

Zero Trust Model

The adoption of the Zero Trust security model is gaining importance, operating under the principle that no entity within the network is inherently trustworthy. This model requires rigorous authentication and authorization, becoming essential as organizations move to the cloud and adopt hybrid work models. Zero trust security emerges as a vital model in this scenario, automatically denying trust within the network and requiring rigorous verification. This approach highlights the need to verify identities and apply access controls, contrasting with traditional security models such as firewalls, which are becoming less effective in dynamic environments (ISACA, 2024).

?

Ransomware 2.0

Ransomware, particularly in the evolved form of "Ransomware 2.0", presents an ongoing and complex threat, employing dual extortion tactics and data theft before encryption, significantly increasing the potential for damage. The proliferation of ransomware and phishing attacks, driven by RaaS - Ransomware as a Service and an entire industry that hides behind it, including payment through cryptocurrency wallets, has reduced the cost and increased the frequency of these attacks. The COVID-19 pandemic has exemplified how types of disruption can trigger spikes in these attacks, with a significant increase in ransomware and phishing observed during the first wave of the pandemic (McKinsey, 2023).

?

Privacy and Data Security

The protection of privacy and personal data faces significant challenges in an increasingly interconnected world. The growing amount of personal data conveyed by connected devices makes them vulnerable to exfiltration and cyber-attacks, posing a threat to both individuals and organizations. One of the main challenges is the disclosure of personal information to the Dark Web, as occurred in an attack in Portugal in mid-2022, where 1.5 million customer records were compromised. This exposure of sensitive information, such as addresses and telephone numbers, can lead to devastating consequences for those affected.

?

Defense In-Depth Approach

To mitigate these risks, the importance of using a multi-layered security approach is highlighted. This includes measures such as encryption, multi-factor authentication and security awareness policies for employees. Encryption is essential to protect both data at rest, data in transit, or data in use (processing in memory), while multi-factor authentication adds an additional layer of security, requiring multiple forms of identity verification. To deal with this dynamic scenario, organizations need to adopt more robust and proactive cybersecurity strategies, such as implementing strict security policies, reducing and hardening the attack surface, adopting Layered Security or Defense in-Depth, the Least Priviledge Principle or Need to Know, Domain Segmentation, Simplification, Vulnerability and Patch Management, Secure Software DevSecOps, and adopting a stance of Awareness about security risks, with a view to Culturization.

?

Geopolitical Conflicts and Impact on Cybersecurity

Geopolitical conflicts have a direct and significant impact on global Cybersecurity. They can lead to an increase in offensive cyber operations, such as digital espionage, attacks on critical infrastructure and disinformation campaigns. For example, tensions between Israel and Hamas, as well as the conflict between Ukraine and Russia, exemplify how geopolitical disputes can lead to an increase in malicious activity in cyberspace. In the case of Israel and Hamas, both sides employed cyberattacks as part of their strategies, targeting critical infrastructure and spreading propaganda or disinformation to influence public opinion. These activities reflect how modern conflicts have transcended the physical domain, incorporating cyberspace as an additional battlefield. As for the conflict between Ukraine and Russia, it has been notable for the extent and sophistication of cyberattacks, many of which aim to destabilize Ukraine, collect intelligence and spread disinformation. Russia has been accused of launching significant cyberattacks against Ukraine, including attacks on power grids and communications systems, demonstrating how nations can use cyber capabilities to achieve geopolitical goals. These conflicts highlight the need to strengthen cyber defenses, develop incident response capabilities, and foster international cooperation to combat cyberthreats that accompany geopolitical tensions. Cybersecurity is not just a technical issue, but also an important strategic and political consideration in the current global scenario.

?

Collaboration for the Greater Good

The need for better sharing of threat information was highlighted by the successive ransomware incidents that affected strategic companies in Portugal. These attacks highlighted the importance of using indicators of compromise (IoCs) to prevent future incidents. The same ransomware that attacked a utilities company in March 2020 also attacked the main air carrier in August 2022. We get the idea that we need the same ISACs that the North Americans created two and a half decades ago, just to share information of threats between ourselves. The importance of collaboration between public, private and educational entities to strengthen cybersecurity maturity and address the shortage of qualified professionals. Collaboration can result in innovative solutions and a more robust approach to cybersecurity. This includes the large-scale adoption of AI, advanced analytics, and cloud computing, aimed not only at automated detection and response to intrusions, but also at developing a diverse and creative cybersecurity workforce that can effectively utilize these tools (Deloitte Insights, 2023).

?

Strategies for Remote Work Environments and Cloud Computing

With the increase in remote work and the migration to cloud computing environments, it has become imperative to redefine information security policies. Organizations recognized the need to update these policies to accommodate the new reality of remote work, where employees are removed from the internal network and traditional protections. This entailed implementing stricter access controls, based on minimum necessary security policies and access functions. For example, only authorized users have access to specific resources, thus ensuring data security. Another measure was the use of VPNs - Virtual Private Networks, to create secure communication channels between remote employees and the organization. VPNs are essential for protecting the transmission of sensitive data over the internet, ensuring transmission segregation and encryption of transmitted data. Additionally, multi-factor authentication has been widely adopted to add an extra layer of security (verifying identity through something the user knows - like a password, but also through something the user has - like a received token, but also for something he is - like a fingerprint, or facial shape).

To further reinforce security, detection, intrusion and security event management tools should be implemented. These tools are essential for monitoring and analyzing security events, identifying potential threats and ensuring a quick response to security incidents. EDR (Endpoint Detection and Response) systems are a security solution focused on detecting, investigating and responding to threats on endpoints, such as desktops, laptops, mobile phones, servers, printers, etc. XDR (Extended Detection and Response) expands this approach beyond endpoints, integrating data from multiple security sources for a more comprehensive view and analysis of threats. While many tout MDR as a panacea (Managed Detection and Response - an outsourced EDR and XDR service, with 24/7 monitoring, detection and response to threats), others defend the extinction of the SOC - Security Operation Center, as incident and events management systems (SIEMs Security Information and Event Management) integrate with orchestration and automatic response systems (SOAR Security Orchestration, Automation and Response), all dynamically managed by artificial intelligence, with an adaptive learning that integrates threat intelligence into all security controls.

?

Promoting an Information Security Culture

Finally, awareness and training of end users plays a fundamental role in protecting the organization's systems and data. CISOs are increasingly aware of the importance of educating employees about potential threats. This involves carrying out awareness exercises, such as quizzes and phishing simulations, targeting different groups of users and measuring the effectiveness of these initiatives through metrics such as participation rate and level of knowledge gained.

There is a clear distinction between education and awareness, both of which play a crucial role in preventing cyberattacks. Education involves specific training and training actions for technicians, while awareness aims to alert ordinary users to cybersecurity risks and best practices. Awareness and education are essential because many cybersecurity incidents originate from human error (the weakest link in Cybersecurity), such as clicking on malicious links that arrive via phishing emails or using weak passwords without resorting to multi-factor authentication. For example, the recent attack on Microsoft executives' emails occurred due to the lack of multi-factor authentication on a single account, even though it was a policy established by the company.

To promote an information security culture within organizations, it is essential to use the appropriate tools to educate and raise awareness among users. This involves segmenting messages according to the target audience and providing training tailored to the needs of each user group. Furthermore, the use of artificial intelligence tools associated with cybersecurity is crucial for a quick and effective response to cyber threats. In a scenario where cyber threats are increasingly complex and rapid, it is important to have AI systems prepared to identify and respond to attacks almost instantly. Rapid response is critical to containing and eradicating security incidents, and AI tools are essential to effectively addressing cybersecurity challenges.
