CYBER RISK

Manage Your
Cyber Risk

Your attack surface is ever-changing, so the goal of your cybersecurity program should be to continuously assess and reduce cyber risk. Unfortunately, many organizations don’t truly understand the cyber risks they face. eSentire helps you proactively identify gaps and opportunities to accelerate risk mitigation and gain peace of mind.

Adopt a Risk-Based Approach to Cybersecurity

As cyber risks grow in number and complexity, business leaders are left wondering just how effective their cybersecurity programs are. Although there are many approaches to developing and managing effective cybersecurity operations, the debate within the industry appears to be: should organizations adopt a maturity-based approach or a risk-based approach?

Using a Maturity-Based Approach: This is the traditional approach to managing cyber risk, wherein organizations aim to achieve a desired level of maturity by implementing certain capabilities and controls. This approach allows an organization to demonstrate the controls and defenses it has built based on standard industry frameworks such as NIST or CMMC.

Using a Risk-Based Approach: This approach allows business leaders to direct investments against the most pressing threats with the goal of effectively reducing risk over time. Since many cybersecurity leaders are forced to operate with limited resources, this more cost-effective approach leads to superior security outcomes when compared to maturity-based or compliance-based approaches.

So, why adopt a risk-based approach to cybersecurity? 

The drawback for a maturity-based approach is that this model may require a hefty financial investment if the focus is placed on building a multi-layer of defense against everything. On the other hand, by leveraging an approach centered on managing cyber risk, business leaders have the option to invest heavily in defenses for the vulnerabilities that affect the business’ most critical areas.

How eSentire Helps Manage Cyber Risk

We move your cybersecurity program ahead, proactively identifying gaps in distributed systems, and building comprehensive cybersecurity strategies that mitigate risk. You gain peace of mind as you build a more responsive security operation that aligns your business objectives with your unique risk and exposure.

A risk-based approach to your cybersecurity program should provide deep visibility into your environment with 24/7 threat detection and response. We recommend adopting a risk-based approach to cybersecurity that includes:

A comprehensive Vulnerability Management program enabling continuous awareness of the threat landscape, vulnerability scanning to understand which systems are inadvertently exposed, and disciplined patch management.

Phishing and Security Awareness Training (PSAT) for all employees to build a culture of cyber resiliency by leveraging a context-relevant training program and driving organizational behavioral change.

24/7 Managed Detection and Response (MDR) with multi-signal attack surface coverage, powered by a strong XDR platform foundation and human expertise, to identify, contain, and respond to threats that bypass traditional security controls.

Digital Forensics and Incident Response (DFIR) expertise through the engagement of an incident response provider on retainer who can support with Security Incident Response Planning, and Emergency Preparedness as well as incident response, remediation, digital forensics investigation, root cause analysis and crime scene reconstruction in the event of a breach.

At eSentire, we work with you to develop a risk-based approach to cybersecurity that aligns your investments to security outcomes that:

Alleviate resource constraints in your organization

Build an enterprise-level information security program, policies and procedures

Meet and exceed compliance requirements

Provide comprehensive threat landscape visibility

Align business objectives with your unique risk and exposure

Using the MITRE ATT&CK® Framework to Reduce Cyber Risk

Cybercrime is continuously growing and evolving making it more difficult for organizations to defend themselves against cyberattacks. We recommend leveraging the MITRE ATT&CK® framework, which provides security leaders with an operational and tactical roadmap you can use to make decisions about where to apply your cybersecurity capabilities.

By using the framework to map the most commonly detected tactics, techniques, and procedures (TTPs), security leaders can start to enhance their cybersecurity programs in order to reduce your overall cyber risk.

What is the MITRE ATT&CK® Framework?

The ATT&CK framework is a curated knowledge base and model for cyber adversary behavior that reflects the phases of an adversary's attack lifecycle and the platforms they are known to target. The tactics, techniques, and procedures (TTPs) are derived from real-world observations of cyberattackers.

The advantage of rooting your decisions within the ATT&CK framework while using a risk-based approach to develop your cybersecurity program is that your team can identify the gaps and vulnerabilities specific to your business & industry, and allocate your security budgets to mitigate the most pressing vulnerabilities first.

However, many organizations are left wondering what happens once their coverage has been mapped. In other words, how can you translate the ones and zeros of the MITRE ATT&CK® language into the dollars and cents of costly business disruptions and irreparable reputational damage? How do you contextualize coverage in terms of quantifying risk reduction?

Quantifying Organizational Cyber Risk

While it’s not feasible to build business responses for each TTP found in the MITRE ATT&CK® framework, as a cybersecurity leader, you should familiarize yourself with the most common TTPs and understand the associated cyber risks you’re facing. Based on the severity of the observed technique, your team can build a proactive response designed to counter the cyber threat and reduce your business risk.

This is a crucial first-step in developing a risk-based approach to cybersecurity. The end goal is to look inward to identify the set of gaps and critical vulnerabilities that are most impactful for your specific business, and mitigate them first. To be successful in using a risk-based approach, here are some questions you can ask yourself:

Maturity-Based Approach vs. Risk-Based Approach: What’s the Right Answer?

Take Control of Cyber Risk

By utilizing a risk-based approach, instead of a maturity-based approach, your team will be able to maintain deep visibility into your environment for 24/7 threat detection and response. We recommend prioritizing your resources across three key services areas:

Managed Risk and Vulnerability

  • Button down initial access vectors
  • Develop robust security strategy, training initiatives, and testing cadence
  • Assessments and testing through Penetration Testing, Vulnerability Scanning, Red Team Operations, Security Awareness Training, and Phishing Programs
