In the ever-evolving realm of cybersecurity, it is not only important to be prepared but to be proactive. Threat Exposure Management (TEM), a top trend for 2023 according to Gartner, is the embodiment of this philosophy, presenting a pragmatic, effective, and systemic approach to continuously refine cybersecurity optimization priorities12.
Understanding Threat Exposure Management
In essence, TEM is a comprehensive strategy that focuses on understanding an organization’s exposure to potential cyber threats and addressing gaps in its security posture. It involves identifying vulnerabilities, quantifying risk, and implementing controls to reduce exposure to an acceptable level.
TEM goes beyond traditional vulnerability management by continuously assessing, analyzing, and prioritizing threats based on their potential impact. This enables organizations to make more informed decisions and optimize their security resources.
The Need for Continuous Approach
Cyber threats are not static; they change and evolve constantly. As a result, the traditional method of periodic vulnerability scanning and patching is no longer enough. The continuous approach of TEM allows organizations to stay ahead of the evolving threat landscape, ensuring they are always prepared and protected.
Continuous TEM involves regular monitoring and assessment, swift remediation of vulnerabilities, and constant refining of security measures based on new information. It offers a real-time view of the organization’s threat landscape, allowing for immediate action when necessary.
Benefits of Threat Exposure Management
Implementing TEM provides several key benefits:
TEM provides a complete view of an organization’s security posture, revealing all potential vulnerabilities across its systems. This visibility is crucial in understanding what needs to be protected and how best to do it.
Prioritized Risk Management
Not all vulnerabilities pose the same level of risk. TEM helps organizations prioritize their risk management efforts, focusing on the vulnerabilities that pose the greatest threat to their critical assets.
Optimized Resource Allocation
By focusing on the most significant threats, organizations can optimize their security resources, ensuring that they are being used where they are most needed.
Many regulatory standards require organizations to conduct regular vulnerability assessments and risk analysis. Implementing TEM can help meet these requirements and demonstrate compliance.
Implementing Threat Exposure Management
Successful implementation of TEM requires the right combination of people, processes, and technology. It starts with developing a clear understanding of the organization’s assets and their value. This information is then used to assess potential threats and vulnerabilities, and to determine the potential impact of a successful attack.
Next, organizations need to develop and implement appropriate controls to mitigate identified risks. These controls may include technical measures such as firewalls and intrusion detection systems, as well as administrative controls such as policies and procedures.
Finally, organizations need to continuously monitor and reassess their threat landscape, making adjustments as necessary to stay ahead of evolving threats.
In an era where cyber threats are constantly evolving, a continuous approach to cybersecurity is no longer a luxury but a necessity. Threat Exposure Management provides organizations with a pragmatic and effective strategy to continuously optimize their cybersecurity efforts, ensuring they are always prepared to face the latest threats
