• Cyber Defense Forensics Analyst: Analyzes digital evidence and investigates computer
security incidents to derive useful information in support of system and network vulnerability
mitigation.

While this is just a snapshot, each role requires extensive experience in cyber security and a combination
of hard and soft skills — from software engineering and programming, computer and network forensics,
network infrastructure management, and threat analysis to critical thinking, problem-solving, fast and
strategic reaction, attention to detail, and the desire to learn — it’s a long list, driven by the complexity of
cyber security.

If you need more convincing of the human intelligence required to defend IT infrastructures, applications,
devices, and users, look back at December 2020’s massive SolarWinds supply chain attack, or the
Exchange vulnerabilities patched by Microsoft in March.

In the case of SolarWinds, threat actors introduced a backdoor to Orion customers by modifying binaries
supplied by SolarWinds in a supply chain attack that impacted more than 33,000 global customers.
Following the installation of this backdoor, the attackers were able to gain access to networks of interest
and leverage additional capabilities, such as compromising code signing certificates and forging
authentication tokens — notoriously difficult to detect by even the most skilled security practitioners. The
attack went undetected for months, enabling the threat actors to collect valuable intelligence from private
companies, as well as U.S. agencies that included the Department of Homeland Security and the
Treasury Department.

In the Microsoft Exchange incident, attackers actively exploited four zero-day vulnerabilities in Exchange
Server. This left IT teams scrambling to patch systems and required incident response experts to
develop tools and techniques to assess the impact and verify integrity following the compromise. During
the event, security teams had to stay on top of the advice and guidance continuously updated
from Microsoft and government agencies, while racing against malicious actors who were working to
weaponize the exploits for ransomware.

These are both examples of security events that required deep expertise in cyber security forensics and
incident response in order to act quickly and accurately to assess the impact to businesses.

The reality is, your immediate, or outsourced team, should have the cyber security training and expertise
to understand attack techniques, threat behavior, the scope and severity of each new threat as it arises,
the potential impact to your organization, and how to react quickly and effectively to mitigate active threats
or risks. Teams should also bring the skills to evaluate and manage the technologies powering an
organization’s threat defense — whether that is hands-on engineering and software development or
hiring outsourced experts that add this value.
