Internal intelligence feeds are derived from data and information collected within an organization's own networks and systems. Jian's activities, such as real-time assessment of system activities and acquiring feeds from honeynets, P2P monitoring, infrastructure, and application logs, fall under the collection of internal intelligence feeds. These feeds are crucial for identifying potential threats and vulnerabilities within the organization and form a fundamental part of a comprehensive threat intelligence program. They contrast with external intelligence feeds, which are sourced from outside the organization and include information on broader cyber threats, trends, and TTPs of threat actors.References:

Centralized storage architecture refers to a system where data is stored in a localized system, server, or storage hardware. This type of storage is capable of holding a limited amount of data in its database and is locally available for data usage. Centralized storage is commonly used in smaller organizations or specific departments within larger organizations where the volume of data is manageable and does not require the scalability offered by distributed or cloud storage solutions. Centralized storage systems simplify data management and access but might present challenges in terms of scalabilityand data recovery.References:

Advanced Persistent Threats (APTs) are characterized by their 'Multiphased' nature, referring to the various stages or phases the attacker undertakes to breach a network, remain undetected, and achieve their objectives. This characteristic includes numerous attempts to gain entry to the target's network, often starting with reconnaissance, followed by initial compromise, and progressing through stages such as establishment of a backdoor, expansion, data exfiltration, and maintaining persistence. This multiphased approach allows attackers to adapt and pursue their objectives despite potential disruptions or initial failures in their campaign.References:

• "Understanding Advanced Persistent Threats and Complex Malware," by FireEye
• MITRE ATT&CK Framework, detailing the multiphased nature of adversary tactics and techniques

Tracy, as a Chief Information Security Officer (CISO), requires intelligence that aids in understanding broader business and cybersecurity trends, making informed decisions regarding new technologies, security budgets, process improvements, and staffing. This need aligns with the role of a strategic user of threat intelligence. Strategic users leverage intelligence to guide long-term planning and decision-making, focusing on minimizing business risks and safeguarding against emerging threats to new technology and business initiatives. This type of intelligence is less about the technical specifics of individual threats and more about understanding the overall threat landscape, regulatory environment, and industry trends to inform high-level strategy and policy.References:

• "Cyber Threat Intelligence and the Lessons from Law Enforcement," by Robert M. Lee and David Bianco, SANS Institute Reading Room

For gathering strategic threat intelligence that provides a high-level overview of the current cybersecurity posture, potential financial impacts of cyber activities, and overarching threats, sources such as Open Source Intelligence (OSINT), Cyber Threat Intelligence (CTI) vendors, and Information Sharing and Analysis Organizations (ISAOs)/Information Sharing and Analysis Centers (ISACs) are invaluable. OSINT involves collecting data from publicly available sources, CTI vendors specialize in providing detailed threat intelligence services, and ISAOs/ISACs facilitate the sharing of threat data within specific industries or communities. These sources can provide broad insights into threat landscapes, helping organizations understand how to align their cybersecurity strategies with current trends and threats.References:

Incorporating a scoring feature in a Threat Intelligence (TI) platform allows SecurityTech Inc. to evaluate and prioritize intelligence sources, threat actors, specific types of attacks, and the organization's digital assets based on their relevance and threat level to the organization. This prioritization helps in allocating resources more effectively, focusing on protecting critical assets and countering the most significant threats. A scoring system can be based on various criteria such as the severity of threats, the value of assets, the reliability of intelligence sources, and the potential impact of threat actors or attack vectors. By quantifying these elements, SecurityTech Inc. can make informed decisions on where to invest its limited funds to enhance its security posture most effectively.References:

True attribution in the context of cyber threats involves identifying the actual individual, group, or nation-state behind an attack or intrusion. This type of attribution goes beyond associating an attack with certain tactics, techniques, and procedures (TTPs) or a known group and aims to pinpoint the real-world entity responsible. True attribution ischallenging due to the anonymity of the internet and the use of obfuscation techniques by attackers, but it is crucial for understanding the motive behind an attack and for forming appropriate responses at diplomatic, law enforcement, or cybersecurity levels.References:

• "Attribution of Cyber Attacks: A Framework for an Evidence-Based Analysis" by Jason Healey
