Vulnerability testing is the process of identifying, analyzing, and reporting security weaknesses in an IT system, also known as vulnerability assessment. These vulnerabilities often exist in software applications, hardware, networks, or other IT infrastructure, even in cloud solutions.
The goal is to detect the potential threats and prioritize their resolution to minimize the risk of cyberattacks or data breaches. No matter if you are a small business, a mid-sized company, or an enterprise, your IT systems can be vulnerable even when taking all the necessary precautions.
Note: A vulnerability scan is an automated process used to identify potential weaknesses in a system’s security defenses. Unlike a scan, security vulnerability testing goes deeper by analyzing and prioritizing the risks, offering actionable steps to remediate critical threats.
Key Steps in Vulnerability Testing
Vulnerability audits start with careful planning, which also includes double checks on every potential threat. Even when you renew your outdated hardware and software, some risks still exist, and the following steps will help you assess the situation:
- Planning: Define the scope, objectives, and methodology of the assessment. Decide what tools will be used or whether you’ll outsource part of the activities.
- Scanning: Use automated tools to scan systems and networks for known vulnerabilities. Keep in mind that some threats require manual actions.
- Analysis: Examine the identified vulnerabilities to determine their potential impact and exploitability. Also, you can easily come up with solutions during this phase.
- Reporting: Document the findings, including the severity of each vulnerability and recommended activities.
- Remediation: Fixing the vulnerabilities through patches, configuration changes, or other corrective measures to ensure IT system efficiency.
- Rescanning: Verify that the vulnerabilities have been resolved and no new issues have been introduced.
Surely, specific cases require specific actions. By working with IT professionals, you’ll get a tailored approach for each step and skip those that aren’t relevant (or add new phases in the case of pretty vulnerable IT systems.)
Types of Vulnerability Testing
As you suppose, there’s not only one approach to testing IT vulnerabilities. That’s why there are a few types of vulnerability testing you should consider, including:
- Network-based Testing: Focuses on vulnerabilities in network infrastructure, such as firewalls, routers, and switches.
- Host-based Testing: Targets vulnerabilities on individual devices like servers or workstations.
- Application Testing: Identifies flaws in software applications, such as SQL injection or cross-site scripting (XSS).
- Wireless Network Testing: Examines weaknesses in wireless networks and their configurations.
- Database Testing: Assesses databases for misconfigurations, weak credentials, or outdated software.
Sometimes, you may have problems with one or two aspects of the IT infrastructure, which means partial testing only. Ensure you’re aware of the most vulnerable segments of your company, so you can precisely test them, and improve as needed.
Benefits of Vulnerability Testing for IT
You may think, why test something that works just fine? But even if it works fine, it may have some vulnerabilities hidden behind the perfect performance. The regular testing:
- Reduces the risk of cyberattacks by addressing weaknesses proactively.
- Helps organizations comply with industry standards and regulations.
- Enhances overall IT security posture.
- Prevents potential financial and reputational damage.
Regular vulnerability testing, combined with other security measures like penetration testing and continuous monitoring, is crucial for maintaining robust IT security.
How Managed IT Companies Handle Vulnerability Testing
Managed IT companies often provide services to handle parts or even the entirety of vulnerability testing as part of their managed security services. These companies help businesses identify and mitigate risks by leveraging their expertise and tools, allowing the client to focus on core operations. Here’s how they do that:
Automated Vulnerability Scanning
Managed IT providers use sophisticated tools to perform regular scans of your IT systems to identify known vulnerabilities in software, hardware, and network configurations. Based on that, they propose a recovery strategy to help you avoid the vulnerability risks while ensuring consistent performance all the time.
Patch Management
Patch management is the process of fixing the vulnerabilities only to ensure the efficiency of the IT system. Managed IT companies manage the process of applying security patches and updates to fix identified vulnerabilities, ensuring systems remain up to date. In return, they recommend additional measures to prevent further issues with the network and systems.
Risk Analysis and Reporting
Patch management is usually not enough to fix all the vulnerabilities, but it gives enough time for a more strategic approach to testing and implementation. Managed IT providers assess the severity of vulnerabilities and prioritize them based on potential impact, creating detailed reports with actionable recommendations.
Configuration Management
Sometimes, the hardware configuration is the biggest threat, especially when using outdated computers and old machines to keep things going. So, managed IT providers ensure systems and networks are securely configured to minimize exposure to vulnerabilities.
Ongoing Monitoring
Managed IT companies offer continuous monitoring to detect and respond to emerging vulnerabilities in real-time. Their cybersecurity and recovery strategies include vulnerability monitoring so they can act immediately before a more serious problem occurs. As a result, you get a trusted partner who works for you, even in challenging periods of your business.
Compliance Support
Sometimes, companies aren’t sure what regulations to follow when taking specific actions. But, managed IT companies understand the compliance requirements so well. They assist in meeting industry-specific compliance requirements (e.g., HIPAA, PCI DSS) by conducting vulnerability assessments and documenting efforts.
Optional Penetration Testing
Penetration testing is a simulated cyberattack performed on an IT system to identify and exploit security vulnerabilities. It helps assess the system’s defenses and provides actionable insights to strengthen its overall security. Some managed IT providers also offer penetration testing, which complements vulnerability testing and recovery strategy.
Advantages of Using Managed IT for Vulnerability Testing
Vulnerability testing may not be so challenging for companies with in-house IT teams. Still, smaller businesses may need a more convenient solution. As mentioned, managed IT companies can perform it and report eventual threats. But why choose that option? Because of the:
- Expertise: Access to certified security professionals with extensive knowledge of best practices.
- Cost-effectiveness: Reduces the need for in-house security teams and expensive software tools.
- Scalability: Suitable for businesses of all sizes, from small organizations to large enterprises.
- Proactive Security: Helps prevent security breaches by addressing vulnerabilities before they are exploited.
- Integrated Services: Often combined with other IT security measures like incident response and disaster recovery.
By partnering with a managed IT provider, businesses can enhance their security posture while saving time and resources. However, organizations retain the ultimate responsibility for implementing recommendations and maintaining overall compliance.
Why is Vulnerability Testing Critical?
Even with secure development practices, vulnerabilities can emerge from frequent updates, putting businesses at risk. Proper vulnerability testing mitigates these risks, which include:
- Customer Loss: Data breaches damage reputation, and many customers avoid businesses that experience such incidents. Even minor vulnerabilities, like an SQL injection flaw, can expose sensitive data and ruin trust.
- Financial Damage: Cybercrime is projected to cost $10.5 trillion annually by 2025. Breaches lead to fines, settlements, and hidden costs like legal fees and PR, with some companies losing a huge portion of their revenue.
- Image Damage: Vulnerabilities don’t only attack the internal workflow, but may affect customer satisfaction. After that, your company may suffer a ruined image and reputation, which can be damaging to your success in the long run.
