Cyber threat intelligence
This article may be too technical for most readers to understand. Please help improve it to make it understandable to non-experts, without removing the technical details. (October 2015) (Learn how and when to remove this template message)
According to CERT-UK, Cyber Threat Intelligence (CTI) is an "elusive" concept. While cybersecurity comprises the recruitment of IT security experts and the deployment of technical means to protect an organization's critical infrastructure or intellectual property, CTI is based on the collection of intelligence using open source intelligence (OSINT), social media intelligence (SOCMINT), human Intelligence (HUMINT), technical intelligence or intelligence from the deep and dark web. CTI's key mission is to research and analyze trends and technical developments in three areas:
Those accumulated data based on research and analysis enable states to come up with preventive measures in advance. Considering the severe impacts of cyber threats, CTI has been raised as an efficient solution to maintain international security.
- Tactical: attacker methodologies, tools, and tactics - relies on enough resources and involves certain actions to go against potentially dangerous actors trying to do infiltration
- Technical: indicators of specific malware
- Operational: details of the specific incoming attack, assess an organisation's ability in determining future cyber-threats
- Strategic: high-level information on changing risk (strategic shifts) - senior leadership is required[by whom?] for thorough determination to critically assess threats
In the financial sector, the CBEST framework of the Bank of England assumes that penetration testing is no longer adequate to protect sensitive business sectors, such as the banking sector. In response, the UK Financial Authorities (Bank of England, Her Majesty's Treasury, and the Financial Conduct Authority) recommend several steps to guard financial institutions from cyber threats, including receiving "advice from the cyber threat intelligence providers operating within the UK Government".
Benefits of tactical cyber intelligence
- Provides context and relevance to a large amount of data
- Empowers organisations to develop a proactive cybersecurity posture and to bolster overall risk management policies
- Informs better decision-making during and following the detection of a cyber intrusion
- Drives momentum toward a cybersecurity posture that is predictive, not just reactive[page needed]
- Enables improved detection of advanced threats
Challenges and Controversies on the value of cyber threat intelligence
There are also challenges that cyber threat intelligence research is facing, including some controversies on the value of threat intelligence and whether it really works. Different experts have voiced their concerns on whether TI is really effective in its current state.    Conversely, others have argued that Threat Intelligence can help identify vulnerabilities and ways to resolve them.
Cyber threats involve the use of computers, software and networks. During or after a cyber attack technical information about the network and computers between the attacker and the victim can be collected. However, identifying the person(s) behind an attack, their motivations, or the ultimate sponsor of the attack, is difficult. Recent efforts in threat intelligence emphasize understanding adversary TTPs.

CTI and political risk
Influential geopolitical countries, such as the US, Russia, China and Iran, use cyberspace as an extension of their foreign and intelligence collection policies. To achieve these objectives, they have formed APT units that primarily specialise in the following fields:
- Collection of sensitive data from business or government computer systems
- Electronic penetration or sabotage of critical infrastructure computer systems (for example, read about Stuxnet)
A combination of CTI with political risk analysis, which includes a deep understanding of current geopolitical disputes and leadership ulterior political motives, can help analysts understand future cyberwarfare patterns.
