As cyber threats continue to evolve and become more dangerous, organizations need to ensure their networks are constantly protected from such threats. It is with this consideration in mind that has led many enterprises to adapt what is called vulnerability management.
What is Vulnerability Management?
Vulnerability management is a comprehensive, proactive approach to safeguarding the business’s digital infrastructure. It involves systematically identifying, categorizing, prioritizing, assessing, and resolving security vulnerabilities in your network. It not only helps to detect potential threats but also provides strategies to mitigate them, securing your network from various cyber risks.
Given its importance, vulnerability management as a strategy is not a recommendation but an absolute necessity. Especially so for small and medium businesses that are most vulnerable to cyberattacks because they are perceived as “easier targets” by cybercriminals partly due to the lack of resources they have in implementing more stringent security measures.
The Vulnerability Management Cycle
Vulnerability management involves going through several key steps, with each playing a critical role in forming a strong line of defense against cyber threats.
1. Discovery
The starting point wherein all hardware and software used within the organization is identified and catalogued, including all endpoints, workloads, and assets. This helps ensure awareness of every potential entry point that an attacker could exploit.
2. Vulnerability Identification
All vulnerabilities within the system are identified. These are usually software flaws that cybercriminals can potentially exploit.
3. Risk Assessment
This step determines how much of a threat each one poses to the system and the organization as a whole
4. Prioritization of Remediation
The organization determines which vulnerabilities to address first, depending on the potential harm a vulnerability could cause if exploited, as well as the likelihood of it being exploited.
5. Remediation
This is the process where the fix to identified vulnerabilities are applied, such as the use of patching software, tweaking configurations, or, sometimes, replacing hardware.
6. Verification
After remediation, it’s important to check that the fixes have worked and that the vulnerabilities are indeed resolved.
7. Reporting
The final step is to generate reports about the vulnerabilities found, how they were addressed, and what actions are needed in the future. This ensures that the management team is well-informed about the security state of the business, and can make strategic decisions accordingly.
Challenges in Implementing Vulnerability Management
Implementing a vulnerability management program is not without its challenges. Resource constraints are one of them, especially for small and medium businesses that often face budgetary and time constraints, making it difficult to devote sufficient resources to comprehensive vulnerability management.
Lack of expertise is another challenge as vulnerability management is a specialized field requiring skilled personnel, something smaller businesses struggle to find or afford.
There is also the matter of business continuity. Remediation steps, such as patching and system upgrades, can disrupt business operations which some businesses cannot afford to have with the target revenues they hope to achieve.
Security culture is another challenge. Employees and senior management may resist the disruption caused by vulnerability management due to a lack of awareness about security issues and concerns.
Overcoming Implementation Challenges
To overcome these issues, businesses can consider outsourcing to managed security service providers or adopting Vulnerability Management as a Service (VMaaS). Such can help alleviate resource and expertise constraints as they can handle the complex task of managing vulnerabilities at manageable costs, allowing businesses to focus on their core operations.
Business continuity can be maintained through careful planning and scheduling of remediation actions during off-peak hours. Also, a well-structured vulnerability management program can help predict potential disruptions, allowing for proactive planning to minimize business impact. Management is an investment in the long-term security and resilience of the business.
Encouraging security awareness among employees should also be in place to reduce the risk of breaches caused by human error. Regular training sessions should be conducted, covering topics such as phishing, password security, and safe internet practices. By fostering a culture of vigilance, businesses empower their workforce to act as a crucial first line of defense in their cybersecurity strategy.
Bottom Line
Vulnerability management is crucial in protecting the business from cyber threats as it enables the business to systematically identify and address potential weak spots in a proactive and immediate manner. A proactive investment in vulnerability management not only secures digital assets but also safeguards business reputation and customer trust.
