Why is Exposure Management Not Enough? What is CVEM?
The need for exposure management tools has skyrocketed, and every organization is looking for exposure management software to safeguard its network. But is exposure management alone enough?
Before we delve into this, let’s understand what exposure management is.
What is Exposure Management?
Exposure management is a process of detecting, assessing, and remediating vulnerabilities and other security risks before they get exploited. It involves protecting organizations from potential cyberattacks and following the prevention-first approach rather than waiting for an attack to happen.
Here’s how exposure management typically works:
-
Vulnerability Detection and Assessment: The first step in exposure management is conducting a continuous and automated scanning and assessment of the organization’s digital assets to identify potential risks.
-
Risk Prioritization: Once vulnerabilities are identified, they must be prioritized based on their severity, technical impact, business context, and impact on high-fidelity attacks.
-
Patch Management: Vulnerabilities and cyber risks detected must be remediated or mitigated through timely patch application.
-
Security Controls Implementation: Exposure management also involves implementing various security controls and measures to protect against known vulnerabilities and potential threats.
How did Continuous Threat Exposure Management Become the Talk of the Town?
Gartner recently coined the term CTEM (continuous threat and exposure management), which talks about the continuous process of monitoring, evaluating, and reducing the level of exploitability of an attack. This term helped exposure management to build its momentum and got attention to its benefits such as:
- Prioritize risks
- Gaining actionable insights
- Operational efficiency
- Resource allocation
- Competitive advantage
But what’s the point of remediating an exposure after it is exploited?!
Doesn’t it make sense to prevent the risk before it gets exploited?
Let me ask you again: do you still think exposure management is enough?
Why is CVEM a Need of the Hour?
Many myths are circulating around Continuous Threat and Exposure Management and modern vulnerability management:
CTEM Myth 1: Existing vulnerability management is not continuous or automated
Reality: Vulnerability management is continuous and is end-to-end automated. In tools like SanerNow, vulnerability scanning is done within minutes, and also can detect vulnerabilities beyond CVEs.
CTEM Myth 2: Patch Management is not automated, and the mean time to remediate a vulnerability is in months.
Reality: Patch Management is automated, and the patching cycle is completed within days or even instantly. Patching is easier with integrated vulnerability and patch management, and all the vulnerabilities and other security risks are remediated instantly.
With SanerNow achieve 95% patch compliance within two days.
CTEM Myth 3: Vulnerability prioritization is not found in current tools
Reality: Prioritization of vulnerabilities was present based on the CVSS scores. It is now more accurate with CISA-SSVC guidelines that prioritize vulnerabilities based on business context, technical impact, high-fidelity attacks, and more vulnerability intelligence.
SecPod was the world’s first vendor to implement risk-based prioritization based on CISA-SSVC guidelines.
CTEM Myth 4: “Continuous Threat Exposure Management” can work on its own
Reality: Continuous threat detection is not possible without continuous vulnerability detection. Continuous threat and Exposure management will still need vulnerability management to feed information about the latest risks.
Adopting Continuous Vulnerability and Exposure Management solves the problem of continuity, remediation, and automation and also identifies vulnerabilities beyond CVEs.
Best Practices of Exposure Management
- Automation: Accelerate security process by automating key processes such as asset discovery, vulnerability scanning, risk prioritization, and remediation.
- Regular Audits: Alongside continuous monitoring, perform regular audits of your security process. These audits validate the effectiveness of your strategies and allow for improvements.
- Employee awareness: Human factors often contribute significantly to vulnerabilities. Educating staff on best security practices, such as secure coding practices for developers, adherence to the policy, or even sharing passwords online, is important.
- Explore advanced security tools: It’s time to switch from traditional tools and go for tools that are continuous, automated, and provide a single view of all information
Now, let’s dive deep and understand the concept of CVEM.
What is Continuous Vulnerability and Exposure Management (CVEM)?
We all are aware of what vulnerability management is and how important it is for us to safeguard our IT environment. But when everything in the IT landscape is constantly changing, have we ever wondered if vulnerability management needs any upgrade? What was there in the IT environment two decades ago is not there today, and the security hemisphere has become even more complex post the pandemic. However, the vulnerability management process has almost remained the same with no innovation.
If you have convinced yourselves that siloed approach, relying on different tools for remediation, focusing only on CVEs, and ignoring other crucial security risks are enough to protect your network; it is the same as locking the main door and leaving all the windows in the house wide open and believing you are safe. Modern IT security teams need a Continuous Vulnerability and Exposure Management solution that automatically manages vulnerabilities, exposures, and numerous security risks from a centralized console that strengthens the overall security posture.
Continuous Vulnerability and Exposure Management (CVEM) introduces a fresh perspective to cybersecurity by evaluating an organization’s IT infrastructure security status from a weak perspective and allowing it to strengthen its security posture capable of defending against cyberattacks. The weakness perspective involves the assessment of IT infrastructure that encompasses Devices, Applications, Users/Identities, Data, Networks, and Security Controls.
Pitfalls of Traditional Vulnerability Management: Why Continuous Vulnerability and Exposure Management?
There are numerous reasons why traditional vulnerability management platforms cannot cope with the modern security landscape. Let us look at the three major reasons that present an inevitable need for Continuous Vulnerability and Exposure management.
-
Not Managing Vulnerabilities Beyond CVEs:
All CVEs are vulnerabilities, but not all vulnerabilities have a CVE number. More than 40% of vulnerabilities do not have a CVE identifier assigned. Numerous security risks exist in a network that is as threatening as a software vulnerability. Traditional vulnerability management tools focus only on CVEs or software vulnerabilities, leaving behind other crucial security risks.
-
Lack of Integrated Remediation:
With new vulnerabilities being discovered every passing day, security teams have difficulty keeping a tab on patching them. According to a study by Edge Scan, IT teams take over 58 days to remediate discovered vulnerabilities. The huge delay in patching is due to the traditional vulnerability management platform lacking integrated remediation capability.
They rely on a different tool to patch the vulnerabilities and face hiccups in integrating the vulnerability data and executing the patching process. Delay in patching increases vulnerability exposure, opening gates for numerous cyberattacks. The lack of integrated remediation in vulnerability management tools also leaves IT teams in a dilemma of which tool to use for remediation.
-
Relying on Siloed Interfaces and Multiple Tools:
For different steps of vulnerability management, traditional processes depend on multiple vulnerability management tools, causing chaos and confusion while correlating and assessing the vulnerabilities for mitigation. Due to the complexities involved, the siloed interfaces make it hard for security teams to gain control over the risk exposure. They also create delays between different steps, leading to huge security gaps in your vulnerability management platform.
-
Slow and ineffective scanners:
As the horizon of security risks and vulnerabilities expands, traditional scanners lack the intelligence to detect them. Traditional vulnerability scanners take around 3 to 24 Hrs even to discover the common vulnerabilities. The time taken to discover all risks, including vulnerabilities, will be even longer with these traditional scanners. Longer scanning time directly corresponds to a delay in remediation, leaving the vulnerability to prevail for longer intervals in the network.
Some vulnerability scanner produces false-positive results and consumes huge bandwidth while scanning hybrid devices. Thus, ineffective vulnerability scanning is a major let down for the whole vulnerability management process.
-
Unable to keep up with the volume of vulnerabilities:
Tens of thousands of vulnerabilities are discovered every year, and the volume of vulnerabilities released in the NVD database is mammoth. The year 2023 ended with a total of 26,447 vulnerabilities, surpassing the previous year’s count by over 1500 CVEs. Security teams face numerous challenges in keeping up with the increased volume of vulnerabilities. To add to this, the number of security risks in the network is also huge.
-
Poor clarity on what to remediate first:
According to a study by ESG, 43% of security admins have challenges understanding which vulnerability to remediate first. After detecting a huge pile of vulnerabilities and risks, it is critical to identify and remediate the high-risk ones to minimize attacks. Traditional vulnerability management tools lack the right techniques to prioritize vulnerabilities and risks based on severity.
-
Lack of remediation controls beyond patching:
Patching is not the only remediation measure to fix vulnerabilities and other security risk exposures. As the horizon of vulnerabilities and security risks expand, numerous remediation controls are needed to fix different types of vulnerabilities. Traditional vulnerability management tools lack these controls and restrict security teams from going beyond patching to fix other risk exposures.
-
Unable to align vulnerability management goals with security compliance:
Popular industry compliance standards like HIPAA, PCI, NIST, and ISO propose numerous system hardening controls and vulnerability management measures to tighten security. Many traditional vulnerability management tools in the market are not equipped with sufficient features to align with these security benchmarks. Thus, security teams rely on different tools to enforce security compliance, making it a challenging goal to achieve.
-
Lack of Exposure Visibility:
