Cyber Threat Defence (CTD) is a computer network defence mechanism which includes response to actions and critical infrastructure protection and information assurance for organisations, government entities and other possible networks. Makarov Power 6 Cyber Threat Defence focuses on preventing, detecting and providing timely responses to attacks or threats so that no infrastructure or information is tampered with. With the growth in volume as well as complexity of cyber attacks, Threat Defence is essential for most entities in order to protect sensitive information as well as to safeguard assets.

 

How Does Cyber Threat Defence Work?

 

With the understanding of the specific environment, Cyber Threat Defence (CTD) analyses the different threats possible to the given environment. It then helps in devising and driving the strategies necessary to counter the malicious attacks or threats. A wide range of different activities is involved in Threat Defence for protecting the concerned entity as well as for the rapid response to a threat landscape. These could include reducing the appeal of the environment to the possible attackers, understanding the critical locations and sensitive information, enacting preventative controls to ensure attacks would be expensive, attack detection capability and reaction and response capabilities. Threat Defence also carries out technical analysis to identify the paths and areas the attackers could target.

 

Threat Defence provides the much-needed assurance to run the processes and activities, free from worries about threats. It helps in enhancing the security strategy utilisations and resources in the most effective fashion. Threat Defence also helps in improving the effectiveness of the security resources and security expenses, especially in critical locations.

 

Cyber Threat Defence Base

 

Traditional methods such as commercial security products to block bad sites and malicious software and apply patches to correct vulnerabilities in installed software, continue to be used by most organisations. While effective against some threats, the traditional methods fail to stop advanced attacks and offer no insight into what an adversary does once it has penetrated the network. Organisations are being attacked by well-funded hacking groups who succeed in breaching traditional perimeter defences. We can no longer rely entirely on preventive security measures. If a group is well-funded and determined enough, they are likely to identify an organisation’s vulnerabilities and slip through the net of their perimeter defences.

 

Makarov advises organisations, that they can significantly improve their cyber defence if they adopt a threat based defence strategy. Threat based defence sensibly uses the knowledge gained from single, often disparate, attacks and related events to reduce the likelihood of successful future attacks.  

A Power 6 cyber defence engagement will provide a variety of services aimed at long term assurance to your business. The best and most comprehensive threat-based defence hinges on three elements:

 

  • Cyber threat defence intelligence analysis
  • Defensive engagement of the threat
  • Focused sharing and collaboration.

 

Cyber Threat Defence Intelligence Analysis

This intelligence analysis provides information and threat detection signatures that are more durable than current virus definitions. Once the information has been scrutinised, specialists can use it to harden cyber defences and improve ways to anticipate, prevent, detect, and respond to cyber attacks.

 

Using the cyber attack lifecycle or “kill chain, and classic intelligence analysis, cyber threat intelligence analysts developed a framework to better understand and anticipate the moves of cyber adversaries at each stage of an attack.

 

Cyber Threat Defence Intelligence Analysis

 

Makarov Power 6 cyber threat intelligence gathering and analysis is carried out to:

 

  • Collect and archive attack artifacts, including incidents, tactics, targeting data, and loss assessments
  • Associate archived artifacts with the stages of the cyber attack lifecycle
  • Track environmental influences, including politics, technology developments, vulnerabilities, and exploits from both open and sensitive sources
  • Conduct malware reverse engineering to statically and dynamically analyse the characteristics and behaviour of malicious software
  • Analyse the data collected to generate hypotheses about adversaries, their intentions, and their tactics, techniques, and procedures
  • Drawing on all of these analyses to formalise and prioritise defences and react to incidents

 

Data Collection

During almost every step of cyber security operations, massive amounts of data is gathered through logs and other recording systems. In addition to that, your cyber security team makes regular assessments of your security posture and through these assessments, impressive amounts of data concerning your network and systems are collected.

 

With the help of this valuable data that comes from various sources, you can detect any security incidents and make informed decisions in order to contain and eliminate the issue. Moreover, you can even spot the vulnerabilities of your systems and predict possible attacks. Thus, you can take preventive action and stop malicious attacks even before they occur. But to do all these, you need to be able to understand what the data is telling you. In other words, you need to analyse and make sense of it. Cyber defence intelligence is the term that covers the processes of collection and analysis of the data concerning the security of your network and systems.

 

Cyber Threat Intelligence Development

Intelligence analysis requires diligent effort and structural analysis techniques that eliminate biases and uncertainties. Rather than coming up with the conclusions about complex problems, intelligence analysts focus on how they reach such conclusions. As a result of this extra step, the development process of the intelligence becomes rather cyclical. Also, it is this extra step that guarantees that the biases and prejudices of the human factor are considered and even redeemed to some extent. Intelligence analysts then have the intelligence data to take action and  better manage the impact of cybersecurity on the organisation.

 

With the help of the actionable information gathered and developed through cyber defence intelligence practices, your security team can foresee possible security incidents and take necessary preventive measures. In addition, cyber threat defence intelligence allows you to scan for vulnerabilities in your network and systems, and act upon alleviating these vulnerabilities.

 

Threat Engagement

Threat engagement is critical to preventing or detecting future attacks. Defenders have an opportunity during the early stages of the lifecycle to detect and mitigate threats before the treat actor establishes a foothold. During the later stages, incident response  measures are used reactively.

 

After evaluating the risks and prioritising them, cyber security specialists develop a strategy to implement controls that can lower the impact of threats emerging against networks and systems. They install endpoint security software on external devices such as laptops and ensure that firewall access controls are configured properly.

 

Threat engagement ensures defenders proactively look for indicators of a pending, active, or successful cyber attack. Signs can be recognised and developed through retrospective analysis and correlation of threat characteristics observed across the cyber attack lifecycle over time. This approach can put organisations at great risk if they intentionally defer remediation of compromises to learn about a cyber adversary’s actions post-exploit. One solution is to establish synthetic environments that allow cyber defenders to observe an adversary’s post-exploit activity while managing risks.

 

Focused sharing and collaboration

Communities of cyber defenders, sharing and collaborating, working in partnership provides a force-multiplier effect. These collaborations can greatly benefit cyber threat defence intelligence analysis and strengthen cyber defences.
