What is Cyber Threat Intelligence (CTI)?
CTI primarily focuses on analysing raw data gathered from recent and past events to monitor, detect and prevent threats to an organisation, shifting the focus from reactive to preventive intelligent security measures. Ideally, CTI should become the foundation on which an organisation builds its secure, vigilant and resilient capabilities.
Why is CTI important?
CTI ensures organisations are informed and kept up to date with the volume of threats, including the methods, vulnerability, targets and actors within the space.
The potential benefits of having CTI include:
- Prevent data loss
- Detect breaches
- Understand what defence mechanisms are required
- Reveal additional information on threats and motives
- Creates awareness about the existence of other threats
- Provide guidance in the event of a breach
How to build an effective CTI framework for your organisation
- Define what is important: Understand what data analytics networks you own is the first step in identifying what CTI solutions your organisation will need.
- Set specific goals you want CTI to achieve: Defining clear, specific goals helps your organisation understand the current gap, and the tools needed to bridge that gap.
- Continuously refine your CTI feed: Criminals are ever evolving; your organisation need to constantly redefine and evaluate the CTI strategy to provide relevant, up-to-date insights.
- Get expert help: Many organisations choose to hire third-party managed security service providers to gain an entire team of cybersecurity experts at a fraction of the cost.

The digital & cyber trends in 2018
2017 has been an eventful year with some of the largest breaches happening, such as the data breaches of Verizon, Equifax and Uber to list a few of the most recent events. It is also the year when Apple gave us the IPhone X with Face ID and Amazon gave us access to Alexa with its range of Echo devices. Now as 2017 draws to a close, you must wonder what is in store for 2018. Here is what we think you should look out for in the coming year.
- The EU General Data Protection Regulation (GDPR) will be effective 25 May 2018 and non-compliant organisations will face significant impacts. Learn more about the EU GDRP here.
- After the WannaCry ransomware disaster, Crime-as-a-Service (CaaS) will mature and flourish with more tools becoming available for non-technical aspiring criminals to purchase and conduct their own attacks. Read here for more details.
- Data collected from the Internet of Things (IoT) devices such as smart watches will help businesses to develop more intelligent apps and smarter devices by applying Artificial Intelligence (AI) to learn about the human behaviour and identify areas where simple tasks may be replaced or more efficient. Read about each individual trend here.
- An important development from the exponential growth of data is the use of edge computing together with cloud computing to deliver services. Learn more about this trend here.
In addition to the trends above, we have a Tech Trends report for your holiday reading. Deloitte’s ninth annual Tech Trends report identifies trends that are likely to disrupt businesses in the next 18-24 months, from enterprise data sovereignty to digital reality, API imperative, and more.
The trends reflect the macro forces fuelling growth— cloud, digital, and analytics— as well as the innovations built upon this foundation, such as blockchain and cognitive computing.
This year’s report spotlights ongoing transformations of core systems and, more broadly, of IT’s role within the enterprise. As in previous years, we balance these discussions with perspectives on how such changes are impacting IT operations and how companies respond to cyber risk. The pace of change across industries and the globe is only increasing. When organizations recognize connections between new technologies and bring them into harmony, they create something new and greater: the symphonic enterprise. Read Tech Trends reports here.

Cyber Risks Troubling Organisations
One of the most severe cyber risks that organisations continue to face are data breaches. A data breach is an incident where information is stolen or taken from a system without the knowledge or authorisation of the system’s owner.
What are some impacts of a data breach?
- Loss of sensitive, proprietary, or confidential information
- Damage to an organisation’s reputation
- Financial losses
- Customers loss of trust in the organisation
What are some common breach methods?
- A trusted individual or person of authority with access privileges stealing data from an organisation. E.g. Some employees are willing to sell these data for personal profit
- Sensitive data is exposed through mistakes or negligence, mostly by insiders. Eg. More than 50% of the security breaches are due to human error because of failure to follow the organisation’s policies
Payment Card Fraud
- Payment card information being stolen using physical skimming devices, phishing of personal information. Eg. Cyber thieves can use a stolen credit card to buy items online
- Cyber espionage describes the stealing of confidential information stored in digital formats or on computers and IT networks. It is similar to a high tech form of spying
Why data breaches are a significant risk?
- Data breaches are no longer a binary proposition where an organisation either have or have not been breached
- They are wildly variable, from breaches compromising entire global networks of highly sensitive data to others having little to no impact
- According to the Ponemon Institute’s “2017 Cost of Data Breach Study: Global Overview,” the odds are as high as 1 in 4
Technology is meant to enhance and improve both business and consumer aspects of our era today. Unfortunately technology carry risks and open us up to vulnerabilities in the cyber world. To combat cyber attacks, a cyber security maturity framework is recommended. This is a set of standards and best practices from an industry, professional or international bodies which encompasses a logical structure for organisations to benchmark their current cyber capabilities.
A cyber security maturity framework is helpful for an organisation looking to strengthen their security, vigilance and resilience against cyber threats depending on their objectives and cyber-related risks.
There are a number of cyber security maturity frameworks available and while the approach may differ for each framework, organisations will be able to achieve its desired maturity level with any framework.
October 2017 Part 5
Shortage of Cybersecurity Talents
According to the estimates by the Center for Strategic and International Studies, cybercrime costs the global economy US$400 billion per year. With the escalating awareness and prominence of security breaches, securing physical and digital assets for the purpose of confidentiality, integrity and availability are a priority for every organisation. With the vital role cyber security professionals play in the business ecosystem, market demand for cyber security professionals is outpacing supply.
What are their roles and responsibilities?
- Developing and designing enterprise security architecture
- Monitoring and identifying threats in enterprise architecture
- Conducting regular security assessment
Why are they important to organisations?
- Most organisations face challenges in interpreting the detection or mitigation of cyber security threats
- They develop and implement overarching processes
Why is there a shortage?
- As the skills of cyber attackers advances, cyber security professionals are more equipped than an IT professional to understand the tactics, techniques and procedures
- Schools are still graduating cybersecurity majors and that means a lack of experience and exposure to realistic cyber attacks
What can you do?
- Re-examine workforce strategies and improve recruitment outreach
- Have a robust support program for new hires
- Prioritise skills, knowledge, and willingness to learn when recruiting
- Build a local cybersecurity ecosystem
- Develop a strong culture of risk awareness

Anatomy of a Cyber Attacker
Cyber criminals are as diverse as their real-world counterparts. In the last five years, there have been cyber attacks targeted at all sorts of organisations. These criminal activities include breaking into private networks, stealing data and installing ransomware, etc. Every individual is responsible for an organisation’s cyber security and it is vital that you know your enemies and implement effective cyber security measures.
3 Types of Cyber Attackers
- White Hats
- White hats are security researchers or hackers who work for organisations such as the government or cyber security firms, etc. E.g. they work to discover vulnerabilities in software and networks to recommend ways to address these gaps.
2. Black Hats
- Black Hats are criminals, who use their ability to plunder individuals or organisations. They explore or develop software deficiencies and attack methods or other malicious tools to break into machines and steal data, such as passwords, email, intellectual property, credit card numbers or bank account credentials.
3. Grey Hats
- Grey Hats fall into the middle ground between the White and Black Hat categories. Often, Grey Hat hackers look to expose vulnerabilities in a system to inform an organisation of the defect or share it with a group of people. Although, these hackers are not usually motivated by personal gain, their actions may be considered illegal or unethical.
Two factors that determine the type of hacker:
- What are their intentions?
- Are their intentions law-breaking?
Four primary motivators:
- Financial Gain
- Ideology or Politics
- Cyber Protection
Not all hackers have malicious intent. Hacking can be used for good and evil, it boils down to the hacker’s intent. In mainstream media, the term “hacker” is usually related to cyber criminals. A hacker could be anyone regardless of intentions or methods. Hacking is not an illegal activity unless their actions compromises a system without an owner’s permission.

Anatomy of a Cyber Attack
One of the most important knowledge that a cyber security professional would have to know is the Cyber Kill Chain. The Cyber Kill Chain is a seven-stage model that illustrates how cyber criminals get to their victims and target on the system’s vulnerabilities.
7-Stages of Cyber Kill Chain
- Attacker gathers information on the target before launching attack. They usually look for publicly available information on the Internet.
- The attacker uses an exploit and create a malicious payload to send the victim without actual contact with them.
- Attacker sends malicious payload to the victim by email or through other means, which is only one of the numerous intrusion methods the attacker can use.
- The actual exploitation only takes place when the attacker uses an exploit.
- Installing malware on the infected computer is only relevant if the attacker used malware as part of the attack.
6. Command and Control
- The attacker creates a command and control channel to continue operating his internal assets remotely.
- Attacker performs these steps to achieve his actual goals inside the victim’s network.
Knowing and understanding the “7 Steps of The Cyber Kill Chain” enable organisations to trace the movements of an attacker and take the necessary security precautions to prevent such attack from happening.
However, over-focus on this area can also be detrimental to network security. A persistent, highly determined and skilled attacker will always find a way into the network. Thus, instead of analysing old malware, organisation should also focus on detecting ongoing attacks before the damage is done.

May 2017 Part I
Hunting in the Cyberspace
You may have read the recent news about one of the largest cyber attacks, the WannaCry Ransomware. This incident is a wake-up call to all organisations alike, requiring global responsibility and attention to prevent future episodes. We hope to shed light on the fundamentals of cyber security with this 8 part Edu-series to help you understand and protect your data.
Cyber attacks, unlike physical warfare, transcend national borders by compromising computer systems and networks. In this interconnected digital sphere, they threaten the very infrastructures that nations and corporations depend on. Data theft, manipulation of networks and disabling online platforms have amounted to considerable repercussions.
Undeniably, major cyber infringements demonstrate the vulnerability of all organizations’ systems. The growing trend of political cyber attacks has formed a new field of spying: cyber espionage – superpowers have engaged cyber software such as Stuxnet, Flame and DuQu, in an attempt to monitor, collect and control its target.
