Continuous Threat Exposure Management (CTEM)
Operating systems and applications have always contained vulnerabilities. Over time, these have been exploited and, in recent years, increasingly weaponised by attackers with very low skill levels.
Today, most software vendors announce their vulnerabilities to the cybercriminal community on Patch Tuesday every month, allowing them to reverse engineer the ‘patch’ to produce their own exploit packages. Many IT systems remain unpatched for days, months or even years against known vulnerabilities.
What is Continuous Threat Exposure Management?
Vulnerability management has evolved from the classic approach of scanning for public exploits against known vulnerabilities. It now uses additional sources of threat exposure information and combines them with context-aware intelligence to sharpen remediation efforts. The result is a significantly stronger security posture that is improved over time as the Continuous Threat Exposure Management process is followed.
Utilising Microsoft 365 Defender, Microsoft Defender External Attack Surface Management and external threat monitoring, Quorum Cyber’s Continuous Threat Exposure Management delivers:
Scope definition
Covering all your internal assets, your internet footprint and proactively scanning your critical assets such as web farms, application servers and public-facing application programming interface (API) libraries.
Discovery
Continuous active and passive scanning of internal and external facing assets, (including operating systems and software versions) to build a complete inventory and provide you with an accurate risk review of every connected device.
Prioritisation
Using our knowledge of your infrastructure and organisation we make informed decisions and recommendations about which systems and parts of your IT infrastructure need updating first.
Validation
Our service tracks key metrics including your top five risky machines, vulnerabilities and security recommendations to protect critical resources, and we track your exposure score over time to demonstrate how the service is improving your security posture.
Mobilisation
Continual improvements to your security posture as your business evolves, when new projects, departments or business units are brought into scope, or when your risk appetite changes.
Leveraging Microsoft Defender External Attack Surface Management and Attack Surface Intelligence, Quorum Cyber’s CTEM service includes:
A fully automated inventory of all IP connected assets, with full vulnerability management information for assets enrolled into the service.
Measurement of your risk exposure and its improvement over time.
Recommendations of the most important mitigation actions your business needs to take.
Validation that security recommendations are being actioned.
Visibility of what an attacker can see from the internet and how to minimise your exposure.
Why your organisation needs CTEM
Organisational and employee requirements of IT systems are in a constant state of flux. This places incredible pressure on any organisation to understand its attack surface and where its real weaknesses are concealed. Many organisations are siloed and if they use vulnerability management platforms then they suffer from having:
- Hundreds of thousands of rarely actioned vulnerability and exploit suggestions
- A long list of generic remediations that do not take business context into account
- A lack of appetite to invest in a mitigation workflow system to achieve these actions.
With CTEM, our team of experts improve your organisation’s security posture by implementing a process that evolves over time to include additional elements around Operational Technology (OT), the Internet of Things (IoT) and data-based risks.
