Cybersecurity has become one of the most critical aspects of modern business operations, especially for IT executives tasked with safeguarding their organization's digital assets. As cyber threats evolve in complexity and scale, understanding their progression and learning from past incidents is crucial for building resilient defenses. The insights shared during WEI’s recent Cyber Warfare & Beyond event provide IT security leaders a valuable perspective on the major cybersecurity incidents of our time and how they have shaped current strategies.
Understanding Major Cybersecurity Incidents
Several high-profile cybersecurity incidents have dramatically influenced the cybersecurity landscape. Two notable examples are the SolarWinds and Colonial Pipeline attacks. These events not only exposed significant vulnerabilities but also underscored the importance of robust cybersecurity practices and the need for continuous evolution in defense strategies.
SolarWinds Attack
The SolarWinds attack, first identified in 2020 and regarded as one of the most sophisticated cyber espionage campaigns ever seen, was a stark reminder of the vulnerabilities inherent in supply chain security. In this attack, Russian hackers infiltrated SolarWinds' software development process, embedding a backdoor into a widely used network management tool, Orion. This malicious code was distributed to thousands of SolarWinds customers, including several U.S. government agencies and Fortune 500 companies.
Although the SolarWinds event took place four years ago – an eternity in the cyber world – the lessons learned from this incident still carry heavy weight, which are explained in greater detail later in this article. The implications of this breach highlighted the need for organizations to scrutinize their supply chains and enforce stringent security measures throughout. Additionally, it emphasized the importance of having robust incident response plans and advanced threat detection capabilities. Organizations had to reassess their security postures and adopt a zero-trust approach to mitigate such risks in the future.
Colonial Pipeline Ransomware Attack
The Colonial Pipeline ransomware attack demonstrated the crippling potential of cyber threats on critical infrastructure. In May 2021, a ransomware group named DarkSide targeted Colonial Pipeline, one of the largest fuel pipelines in the U.S. The attack forced the company to shut down its operations, leading to fuel shortages and highlighting the vulnerability of essential services to cyberattacks.
This incident underscored the importance of not only protecting IT networks but also securing operational technology (OT) environments. It drove home the necessity for cross-sector collaboration between government and private entities to safeguard critical infrastructure. Moreover, it spurred discussions on the role of regulatory frameworks and the need for organizations to develop robust cyber resilience strategies, including comprehensive backup and recovery plans.
Watch: WEI Cyber Warfare & Beyond Roundtable Discussion
Key Lessons Learned, According To Cyber Thought Leader Michael Sikorski
WEI’s Cyber Warfare & Beyond roundtable discussion featured several prominent panelists to offer their take on the geopolitical landscape and how cybersecurity fits into that equation. Among them was Chief Technology Officer of Palo Alto Networks’ Unit 42, Michael Sikorski. Known as “Siko” in cyber circles, the highly respected thought leader and colleague of mine offered several key lessons from these events for IT executives to consider when enhancing their cybersecurity posture. They include:
-
Investing in Advanced Threat Detection and Response
Advanced persistent threats (APTs) and sophisticated ransomware attacks require equally advanced detection and response capabilities. As WEI has emphasized its “Left of Bang” approach to cybersecurity in the past, investing in next-generation security tools, such as artificial intelligence (AI) and machine learning (ML) driven solutions, can help organizations detect anomalies and respond to threats in real-time. Endpoint detection and response (EDR) and extended detection and response (XDR) solutions are becoming increasingly vital in this regard.
To expand on XDR, the solution is typically capable of working across all valuable data sources—including network, endpoint, cloud, and identity—to deliver a unified view of the attack landscape. It integrates this valuable data to help analysts expose complex attack patterns by breaking down siloes.
The solution, when optimally deployed, uses the latest threat data combined with powerful ML and analytics to provide key insights into system behavior, network traffic, and user activity. By integrating multiple endpoint security tools, it allows security teams to address the full scope of security operations without deploying additional software or hardware.

Importance of Supply Chain Security
The SolarWinds attack was a wake-up call regarding the security of supply chains. Organizations must extend their cybersecurity practices beyond their internal networks to include third-party vendors and partners. Implementing rigorous security assessments and continuous monitoring of supply chain partners is crucial. Additionally, organizations should adopt a zero-trust approach, assuming that any component of their supply chain could be compromised and planning their defenses accordingly.
“There's another SolarWinds (breach), multiple SolarWinds out there that we don't know about yet,” said Sikorski. “And I think that we need to think about the building of software that gets distributed to these companies as a national security issue. And until we do that and think about how to get the production, worry about the supply chain down, the risk is just going to get bigger and bigger.”

Need for Comprehensive Incident Response Plans
Both the SolarWinds and Colonial Pipeline incidents highlighted the importance of having a well-defined incident response plan. Such plans should include clear protocols for detecting, responding to, and recovering from cyber incidents. Regularly testing these plans through simulations and drills can help ensure that all stakeholders are prepared to act swiftly and effectively in the event of a breach.
Combining our mentioned left-of-bang approach with right-of-bang technologies creates a stronger incident detection and response system. The left-of-bang mindset focuses on preventing attacks, while the right-of-bang approach analyzes post-attack data to improve prevention strategies. Information from post-attack analysis, such as how the attack occurred and specific threat indicators, enhances situational awareness and helps prevent future incidents. IT security leaders should aim to disrupt any indicator of an attack early on, as early detection and prevention are the most effective strategies.
-
Embracing a Zero Trust Architecture
The Zero Trust model, which assumes that threats could exist both inside and outside the network, is becoming a cornerstone of modern cybersecurity strategies. This approach involves continuously verifying the identity and integrity of devices, users, and applications accessing the network. Implementing Zero Trust principles can help organizations limit the potential impact of breaches and enhance overall security.
WEI, a leader in network security, has embraced Zero Trust as a core guiding principle even before the term was coined. WEI focuses on robust segmentation and micro-segmentation strategies to minimize the impact and blast radius of attacks. While no single product can deliver Zero Trust, WEI prioritizes Zero Trust network access (ZTNA) solutions to ensure clients have secure access to critical applications.
-
Enhancing Collaboration and Information Sharing
Cyber threats often transcend organizational boundaries, making collaboration and information sharing vital. Public-private partnerships, like those seen in the response to the Colonial Pipeline attack, can enhance collective cybersecurity efforts. Organizations should participate in information sharing and analysis centers (ISACs) and other industry groups to stay informed about emerging threats and best practices.
-
The Role of Cybersecurity Leadership
For IT executives, these lessons underscore the need for proactive leadership in cybersecurity. As stewards of their organizations' digital security, IT leaders must advocate for and implement comprehensive cybersecurity strategies that address both current and emerging threats. This involves not only investing in the right technologies but also fostering a security-first mindset across the organization.
Additionally, IT executives should lead efforts to identify and mitigate risks before they materialize into full-blown incidents. This involves conducting regular risk assessments, vulnerability scans, and penetration testing to identify and address weaknesses in the organization's defenses. By taking a proactive approach to risk management, IT leaders can reduce the likelihood of successful cyberattacks.
-
Strategic Investment in Cybersecurity
Allocating sufficient resources to cybersecurity is essential. IT executives must ensure that their organizations invest in the latest security technologies and maintain up-to-date defenses. This includes not only purchasing advanced security tools but also investing in ongoing training and professional development for cybersecurity staff.
