Now more than ever, keeping your cyber risk in check is crucial. In the first half of 2022’s Cyber Risk Index, 85% of the survey’s 4,100 global respondents said it’s somewhat to very likely they will experience a cyber attack in the next 12 months. And 90% admitted they suffered at least one successful cyber attack in the past 12 months.
Avoiding a breach is not always possible—especially since business and cybersecurity objectives are rarely in sync—but you can still address challenges across your growing digital attack surface, enabling faster threat detection and response. The third highest risk from the CRI 2H’22 was an organisation’s IT security objectives were not aligned with business objectives; a cybersecurity risk assessment can help you take proactive steps to reduce your cyber risk.
What is cybersecurity risk assessment?
Cybersecurity risk assessment provides a valuable analysis of your organisation’s digital attack surface and cyber risk. By continually assessing, scoring, and prioritising individual assets for an up-to-date view of your network, the assessment provides cybersecurity leaders with prioritised and actionable ways to limit the likelihood and impact of a successful attack.
Learning more about the key aspects of risk assessment will make clear why it’s such a valuable tool for CISOs and SOC teams looking to reduce their organisation’s cyber risk.
Once, you could take a full index of your attack surface and easily identify areas of concern. That’s no longer possible in an age of digital transformation and cloud migration, when a growing number of your employees are likely already working remotely. According to CRI 2H’22, an organisation’s IT security function lacking the ability to know the physical location of business-critical data assets and applications was the second highest risk when preparing for an attack. If your organisation’s resources are constantly changing—especially in the cloud, where asset visibility is limited—then a one-time risk assessment is bound to overlook misconfigurations and threats.
Continuous risk assessment analyses and prioritises your organisation’s assets as they change, determining both the likelihood and impact of a successful attack to provide a risk score, along with actionable and prioritised tasks to better secure your digital attack surface.
Cybersecurity risk assessment draws from a wide variety of assets, including user behaviour, security product logs, and cloud app activity, to judge whether your resources are vulnerable to an attack. Your organisation’s exposure from vulnerabilities, misconfigurations, and suspicious activity or data access are weighed alongside its existing security policies and regulatory compliance.
Of course, any threats or vulnerabilities detected in this process are identified and prioritised. But the assessment also digs deeper by analysing identities, SaaS applications, and the content within your network to highlight exactly where the weaknesses in your digital attack surface lie.
Your risk score is not only determined by the likelihood of an attack. Even an organisation with little to no threat exposure must account for the devastating impact just one breach could pose. Assets with a high business value—such as trade secrets, critical infrastructure, and essential networks—could be time-consuming or impossible to replace. One successful attack against these assets might prove more costly for your organisation than a dozen attacks targeting less significant resources.
Factors including asset visibility, content type, and the possible impact of an outage also determine risk score. According to the CRI 2H’22, the top five data types at risk are: human resource (employee) files, business communication (email), financial information, attorney-client privileged information, and trade secrets. By identifying which resources are invaluable to your organisation, and which of these key assets are more vulnerable than you might realise, cybersecurity risk assessment highlights the greatest areas of concern in your digital attack surface.
It’s possible that some of the most dangerous threats in your digital attack surface have already been identified, only to be lost in the never-ending stream of alerts your team faces daily. Cybersecurity risk assessment can help to home in on these threats with prioritised and actionable analysis.
In cybersecurity risk assessment, the status of your software patches and any CVEs in your applications are compiled, then compared against both local threat intelligence and global intelligence from threat researchers. Not only does this analysis provide your team with a list of prioritised threats for immediate remediation, but in some cases instant action can be taken to block these threats from accessing your company’s resources.
A crucial element of cybersecurity risk assessment is its wide-ranging analysis for a complete overview of your digital attack surface. Siloed solutions with limited connections slow down your detection, analysis, and response—especially if their findings are lost in a deluge of alerts.
A cybersecurity platform with prioritised alerts to unite your network’s many security layers and environments will help your team keep pace with your constantly expanding digital attack surface.
When considering a cybersecurity platform to help assess your organisation’s cyber risk, be sure that it will offer central visibility across all your cybersecurity solutions and third-party products.
Trend One features industry-leading XDR and EDR with the broadest native XDR sensor coverage, connecting your entire network to the platform’s attack surface risk management and zero trust secure access capabilities.
