Vulnerability Management Solutions to Ensure Cybersecurity Success
Vulnerability management is a way to reduce risk for your organization, no matter how large or small your organization may be. However, creating a successful vulnerability management program is not a simple task. It requires goal setting, metrics, continuous discovery and monitoring and buy-in from stakeholders across your organization. Not sure where to start? You can make your vulnerability management process stronger with five simple steps.
Achieving continuous discovery and complete visibility into your environment can be challenging without the right tools, but it is vital for discovering and preventing blind spots in your attack surface. An important first step in ensuring vulnerability management success is to identify and map every asset across all of your computing environments.
Next, evaluate the Cyber Exposure of all of your assets, including vulnerabilities, misconfigurations and other security health indicators. Comprehensive vulnerability and misconfiguration assessment is more than running a scan. It’s also using a range of data collection technologies like you’ll find in Tenable.io to identify diverse security issues for your organization.
The third step for vulnerability management program success is to understand your exposures in context to your security and business goals so you can prioritize remediation based on asset criticality, threat context and vulnerability severity.
With the first three steps tackled, you’re on your way to a stronger vulnerability management program. Leveraging machine learning, you can go further to spot hidden data patterns that correlate with future threat activity. This will give you insight into vulnerabilities that may have the highest likelihood of near-term exploitation. From there, you can prioritize which exposures to mitigate first, if at all, and then apply the appropriate remediation process.
A final recommendation is to measure and benchmark your Cyber Exposure to make better business and technology decisions. Report customization in Tenable.io will provide you with easy-to-understand data about the effectiveness of your vulnerability management program and external benchmarking metrics to help you compare your program performance against similar businesses in your industry.
Vulnerability Management and Protecting Your Enterprise from Cyber Exposure
When it comes to vulnerability management, many security teams focus only on their department or team goals. While that traditionally had a degree of success, enterprise vulnerability management programs that align security goals with business goals tend to be stronger.
By aligning your vulnerability management program to your business goals, you can more easily create and analyze success metrics that enable you to communicate your program success to key stakeholders—like C-Suite executives and board members—in ways they understand. This can help you build a stronger enterprise program and get the support of upper-level management so you have access to the resources you need to keep your program flexible, scalable and successful. Here are five best practice recommendations for enterprise vulnerability management:
Identify specific components that are measurable and meaningful and then begin attack surface hardening, asset inventory and patch auditing.
Ensure Data Accuracy
Don't limit the view of your total state of vulnerability. Ensure you're accessing accurate data that’s actionable and timely.
Account for Gaps
To maintain reliable processes and build trust, quickly identify sources where you have patching issues and track them as exceptions.
Deal With Interdependencies and Conflicts
Understand how processes affect individuals and teams within your organization to create a successful vulnerability management program.
Know What to Measure
Instead of trends, measurement should focus on exceptions to discover weaknesses.
Vulnerability Management Blog Bytes
Are you a creature of habit? Do you still use older tools and resources even if they're not as efficient as something new—like a good ol' spreadsheet to manage your vulnerability management program? This can be the case for many security teams. You often have more work than you can accomplish on a given day, so you may be hesitant to explore a new solution, even if it will save you time and improve program efficiencies. Tenable.io is an easy way to let go of the spreadsheet without having to let go of the knowledge you already have and the time you’ve invested in your program.
If you're part of a cybersecurity team, you know there is a never-ending list of vulnerabilities that routinely come across your desk. Traditionally, that’s meant you dig into news headlines, forums and other information exchanges to see which vulnerability is getting the most attention so you can focus your efforts. It can feel like a lost cause. That’s why Tenable’s Predictive Prioritization is changing the way teams handle vulnerability response. Predictive Prioritization leverages data science and machine learning to make it easier for your team to find, patch and remediate vulnerabilities.
In today’s overcrowded world of emerging security threats, fancy new tools and changing regulations, you may get so caught up in patching and fixing the next big thing that you lose sight of basic security fundamentals. One way you can get back to basics is by learning more about your organization’s Cyber Exposure (CE) lifecycle. You can use your CE to ensure your team’s security goals align with your organization’s business objectives. Not sure where to begin? Take a look at the four stages of a Cyber Exposure lifecycle to learn why they’re important for your vulnerability management program.
