With businesses growing at an unprecedented rate, their IT landscapes are also becoming more intricate and complex. Although beneficial for organizational growth, this increases the attack surface, which encompasses a wide array of vulnerabilities and potential entry points that could be exploited to access various organizational assets. As companies strive for innovation and expansion, they are also unwittingly expanding the playground for cyberthreats.

The National Institute of Standards and Technology (NIST) adds more than 2,000 new security vulnerabilities every month to the National Vulnerability Database. Although not all these security vulnerabilities need to be tracked, organizations must find a way to identify and mitigate the ones that do pose a potential threat to their systems. This is where the vulnerability management lifecycle plays a vital role. As a proactive and continuous approach, it not only actively discovers vulnerabilities in a company’s IT assets but also systematically remediates them, safeguarding organizations against potential cyberthreats.

What is the vulnerability management lifecycle?

The vulnerability management lifecycle is an ongoing, cyclical process that helps to systematically identify, prioritize, mitigate, validate and report vulnerabilities lurking within your organization’s IT assets and software applications. It constitutes defined stages and steps that allow you to identify and address vulnerabilities efficiently and continuously. The vulnerability management lifecycle is a subset of a larger, broader vulnerability management framework, and is integral to strengthening your organization’s overall security posture. The vulnerability management lifecycle ensures your organization can identify the most critical vulnerabilities and mitigate them before threat actors wreak havoc.

Why is the vulnerability management lifecycle important?

Every day, new vulnerabilities are discovered, and the techniques used by cybercriminals are becoming more sophisticated. Ignoring the vulnerability management lifecycle in such a situation means leaving the door open for these threats and putting your business directly at risk. Engaging in proactive vulnerability management drastically reduces your attack surface. This helps reinforce the weakest link in your digital armor, lowering the likelihood of successful cyberattacks. It also means business continuity is ensured and compliance with stringent data protection regulations is maintained.

When it comes to the security of your organization, the vulnerability management lifecycle ensures hackers can’t exploit the critical vulnerabilities lurking in the IT assets and cause serious damage. These hackers have a growing stockpile of vulnerabilities at their disposal. Vulnerability management is a response to that and forms a key component of your organization’s cyber-risk management strategy. With a robust vulnerability management lifecycle, you have a formal model for effective vulnerability management programs.

The vulnerability management lifecycle not only supports the technical security of an organization but also its overall health and resilience. Its implications touch every facet of the business, from financial performance and operational efficiency to customer satisfaction and compliance. Hence, recognizing the significance of the vulnerability management lifecycle helps your organization stay resilient, competitive and secure.

Stages of the vulnerability management lifecycle

Security researchers around the world are continuously discovering vulnerabilities in popular software and hardware. This makes the vulnerability management lifecycle a systematic, ongoing process designed to identify, assess and address security weaknesses.

Let’s look at the key stages of the vulnerability management lifecycle.

Stage 1: Discovery

This is the first step in the vulnerability management lifecycle and involves identifying all assets within your organization’s network for building an asset inventory — a catalog of all the hardware and software on your organization’s network. The inventory includes officially sanctioned apps and endpoints as well as any shadow IT assets employees use without approval.

The asset inventory needs to be updated before every round of the lifecycle since new assets are regularly added to organizational networks. The security team uses tools like automated scanners and asset management solutions to ensure the inventory is accurate. The discovery step is critical because it lays the groundwork for the entire process, ensuring no asset is overlooked.

Stage 2: Prioritization

Once all assets are discovered, the next step is to prioritize them based on their criticality to the business, the data they hold and their potential exposure to threats. This stage focuses on protecting the most valuable and vulnerable assets first to avoid pouring time and resources into low-risk vulnerabilities. Prioritization ensures that resources are allocated properly, focusing on areas of higher risk.

Stage 3: Assessment

The assessment stage involves scanning the prioritized assets for vulnerabilities. Automated scanning tools are used to compare the assets against the databases of known vulnerabilities, such as the Common Vulnerabilities and Exposures (CVE) database. The step involves identifying vulnerabilities, their severity and their potential impact on your organization. Assessments of every asset are carried out regularly and in batches to catch new vulnerabilities.

Stage 4: Reporting

Once the assessment phase is complete, the findings are compiled into detailed reports that include information on the vulnerabilities found, their severity and the assets affected. Effective reporting helps you develop and document a security plan, monitor suspicious activities and define known flaws. It gives a clear overview of your organization’s current security posture and identifies areas requiring immediate attention.

Stage 5: Remediation

The remediation step involves fixing the vulnerabilities identified during the assessment period. It can be further broken down into three approaches:

• Remediation: The vulnerabilities are directly addressed by applying patches, updates or configuration changes to eliminate the risk.
• Mitigation: Preventive measures are implemented to reduce the likelihood of vulnerability exploitation if immediate remediation isn’t possible.
• Acceptance: When remediation or mitigation is not feasible due to business constraints, the risk associated with the vulnerability must be accepted. This is informed to you by a thorough risk assessment and requires a sign-off at an appropriate level of management.

Stage 6: Verification

The final stage involves verifying that the vulnerabilities have been successfully remediated or mitigated. This stage is achieved via follow-up scans and assessments to ensure the fixes were applied correctly and no new vulnerabilities were introduced in the process. Verification is vital to close the loop in the vulnerability management lifecycle.

How can the vulnerability management lifecycle help your business?

Implementing the vulnerability management lifecycle within your business isn’t just about ticking off the box for cybersecurity compliance. It’s about transforming your approach to digital threats and fortifying your defenses from the inside out. Let’s explore how this process can be a game changer for your organization and help you stay one step ahead of cyberthreats.

Proactive approach

The beauty of the vulnerability management lifecycle lies in its proactive nature. You don’t have to wait for an attack to reveal your system’s weaknesses. Instead, the process will empower you to identify and address vulnerabilities ahead of time. It ensures that any security gaps are discovered and patched before adversaries can exploit them. This vigilant stance instills confidence among stakeholders that you’re serious about cybersecurity.

Streamlined incident response

With the vulnerability management lifecycle in place, your organization benefits from a streamlined process for identifying and responding to security weaknesses swiftly. This efficiency mitigates the impact of incidents and bolsters your incident response plan, ensuring you’re prepared to tackle new threats head-on.

Security awareness culture

The vulnerability management lifecycle promotes a robust culture of security awareness within your organization. This isn’t just about having a few security experts on board — it’s about embedding a sense of responsibility and vigilance across all the levels of your company. Employees become proactive participants in identifying, reporting and addressing vulnerabilities. This collective awareness acts as an additional layer of defense, enhancing your overall security posture.

Compliance management

Today’s regulatory environment demands that your organization stay compliant. The vulnerability management lifecycle supports your compliance efforts by ensuring you adhere to industry regulations and standards. Whether it’s ISO 27001, PCI DSS or any other regulatory framework, having a robust vulnerability management program showcases your commitment to protecting sensitive data. Beyond avoiding penalties and fines, it’s about preserving your reputation and building trust with customers and partners.

Optimized resource allocation

Resources are finite, and how you allocate them is crucial in making or breaking your cybersecurity efforts. The vulnerability management lifecycle helps to prioritize vulnerabilities based on their severity and impact, ensuring that your resources are focused on addressing the most critical issues first. This data-driven approach ensures that your time, money and personnel are utilized in the most effective manner possible. As a result, the return on your security investments gets maximized.

Common challenges with the vulnerability management lifecycle

While the vulnerability management lifecycle offers a comprehensive framework for safeguarding against cyberthreats, navigating its complexities isn’t without challenges. Understanding these impediments is the first step toward crafting more resilient cybersecurity strategies.

Asset visibility

The current IT environment demands keeping a precise inventory of assets and their vulnerabilities. With the advent of cloud computing, Bring Your Own Device (BYOD) policies and remote work, assets are no longer confined to a controlled network perimeter. This complicates the task of maintaining an up-to-date asset inventory, leaving potential blind spots in your security coverage.

Volume of vulnerabilities

The number of vulnerabilities discovered each year is quite staggering. This places immense pressure on security teams to sift through, prioritize and address these risks. The sheer volume can overwhelm security teams, with critical vulnerabilities getting lost in the noise and exposing organizations to potential breaches.

Insufficient resources

Skill gaps in cybersecurity and budget constraints are realities many organizations face. They limit their ability to manage vulnerabilities effectively. The scarcity of skilled professionals and financial resources can delay the implementation of necessary security measures. As a result, vulnerabilities can be unaddressed for longer than they should be.

Complexity of IT environments

Modern IT environments are complex and diverse. They comprise interconnected technologies and platforms, each with its unique set of vulnerabilities. Managing security across such diverse environments requires specialized knowledge and tools, adding another layer of complexity to the vulnerability management process.

Timely remediation

The time between vulnerability discovery and its exploitation by attackers is often short. Delays in remediation, whether due to resource constraints, the need for thorough testing or the complexity of the IT environment can increase the risk of a security breach.

The ideal way to overcome these challenges is to automate the vulnerability scanning process. Automation enhances asset visibility by continuously scanning and identifying new devices and vulnerabilities as they appear. This ensures no asset goes unnoticed. Also, automating the prioritization and assessment of vulnerabilities helps security teams focus on the most critical issues.
