Today is Computer Security Day so what better time to take a closer look at a hot topic in the realm of cyber security, Threat Exposure Management.
The Association for Computer Machinery (ACM) first inaugurated the day back in 1988 following an attack on -the internet’s predecessor- ARPANET that impacted 10% of the computers connected to it. The event was a major wake up call to the risks posed by malicious actors. Today, some argue that the day should now be renamed to Device Security Day as today many aspects of security now apply to smart phones and other IoT devices.
Threat Exposure Management (TEM) is an increasingly integral part of an organisation’s cyber security. It involves identifying, prioritising, and managing risks across an organisation’s potential attack surface. TEM focuses on understanding the constantly evolving landscape of cyber threats and adapting defences accordingly. This proactive approach ensures that potential security breaches are identified and addressed before they can be exploited by malicious actors. Effective TEM strategies are crucial for maintaining the integrity and confidentiality of sensitive data in today's digital world.
Threat Exposure Management encompasses a comprehensive approach to cyber security, involving several key elements:
Reducing Threat Exposure in an organisation involves several steps, including regular software updates, enforcing strong password policies, and educating employees about cyber security best practices. Implementing multi-factor authentication and maintaining up-to-date antivirus and anti-malware software are also key measures. Regularly backing up data and conducting security audits can further strengthen an organisation’s cyber defences. By taking these proactive steps, businesses can significantly lower their risk profile in the digital landscape:
Scoping – Identify all assets within your organisation’s internal and external attack surface that could be targeted by potential threats.
Discovery – Use threat intelligence and other tools to uncover existing security controls, identify gaps in coverage, and discover potential vulnerabilities.
Assessment & Validation – Evaluate the effectiveness of current security measures using simulated attacks. Validate exposure levels by determining if identified vulnerabilities are exploitable through available attack paths.
Mobilisation & Remediation Planning – Prioritise remediation efforts based on vulnerability prioritization models such as CVSS scores or business impact analysis. Develop a plan for implementing additional security controls or improving existing ones to reduce overall risk exposure.
Effective monitoring and visibility are fundamental to successful Threat Exposure Management. Continuous monitoring of network and system activities helps in early detection of unusual behaviours or potential breaches. This includes tracking user activities, network traffic, and access to sensitive data. Enhanced visibility into an organisation’s IT environment enables quicker response to threats and more effective management of security risks. Utilising advanced monitoring tools, services and technologies, such as Managed Detection and Response (MDR) services and Security Information and Event Management (SIEM) systems, plays a crucial role in maintaining a secure digital infrastructure.
