Which of the following threat intelligence helps cyber security professionals such as security operations managers, network operations center and incident responders to understand how the adversaries are expected to perform the attack on the organization, and the technical capabilities and goals of the attackers along with the attack vectors?

Tactical Threat Intelligence provides information on the immediate Tactics, Techniques, and Procedures (TTPs) of adversaries. It is highly technical and focuses on how threat actors conduct their attacks, including the specific malware used, infrastructure (IP addresses, domains), and tools. This type of intelligence is directly actionable for security professionals in a SOC or IRT. It helps them understand an attacker's methods, configure security controls to block specific attack vectors, and develop detection rules to identify malicious activity based on known adversary behaviors.

A. Analytical Threat Intelligence is not a standard classification; analysis is a process applied to all intelligence types, not a category itself.
B. Operational Threat Intelligence provides insight into specific upcoming attack campaigns, focusing on the "who, when, and where" rather than the technical "how."
C. Strategic Threat Intelligence is high-level, non-technical information for senior leadership about the overall threat landscape and associated business risks.

1. Contos, B. T. (2018). Cyber-Vigilance and Digital Forensics: A Governance, Risk and Compliance Framework. Syngress. Chapter 4, "Threat Intelligence," defines Tactical Intelligence as focusing on "adversary TTPs" for "near-term defensive actions."

2. Cybersecurity and Infrastructure Security Agency (CISA). (2021). Cyber Threat Intelligence. CISA.gov. (CISA's resources distinguish between strategic, operational, and tactical intelligence, defining tactical as technical data, including TTPs, for network defenders).
