What is Vulnerability Assessment? Testing Process, VAPT Scan Tool

Updated October 8, 2021

Vulnerability Testing

Vulnerability Testing also called Vulnerability Assessment is a process of evaluating security risks in software systems to reduce the probability of threats. The purpose of vulnerability testing is reducing the possibility for intruders/hackers to get unauthorized access of systems. It depends on the mechanism named Vulnerability Assessment and Penetration Testing(VAPT) or VAPT testing.

A vulnerability is any mistake or weakness in the system’s security procedures, design, implementation or any internal control that may result in the violation of the system’s security policy.

In this tutorial, you will learn-

Vulnerability assessment for SQL Server

SQL vulnerability assessment is an easy to use tool that can help you discover, track, and remediate potential database vulnerabilities. Use it to proactively improve your database security.

The vulnerability assessment tool is available in SQL Server Management Studio (SSMS) for SQL Server 2012 or later.

For a comprehensive solution with advanced threat protection capabilities, use Microsoft Defender for SQL Servers on machines. To use this Microsoft Defender plan, your SQL Server must be connected to Azure.

For Azure SQL Database, Azure Synapse Analytics, and SQL Managed Instance, use Microsoft Defender for SQL Database.

Vulnerability assessment features

SQL vulnerability assessment (VA) is a service that provides visibility into your security state, and includes actionable steps to resolve security issues and enhance your database security. It can help you:

The VA service runs a scan directly on your database. The service employs a knowledge base of rules that flag security vulnerabilities and highlight deviations from best practices, such as misconfigurations, excessive permissions, and unprotected sensitive data. The rules are based on Microsoft’s recommended best practices, and focus on the security issues that present the biggest risks to your database and its valuable data. These rules also represent many of the requirements from various regulatory bodies to meet their compliance standards.

Results of the scan include actionable steps to resolve each issue and provide customized remediation scripts where applicable. An assessment report can be customized for your environment, by setting an acceptable baseline for permission configurations, feature configurations and database settings.

Prerequisites

This feature is only available on SQL Server Management Studio (SSMS) v17.4 or later. You can find the latest version here.

Getting started

To run a vulnerability scan on your database, follow these steps:

Open SQL Server Management Studio.

Connect to an instance of the SQL Server Database Engine or localhost.

Expand Databases, right-click a database, point to Tasks, select Vulnerability assessment, and select Scan for Vulnerabilities.

You can run a scan that checks for server-level issues by scanning one of the system databases. Expand System Databases, right-click the master database, point to Tasks, select Vulnerability Assessment, and click on Scan for Vulnerabilities.

Tutorial

Use the following steps to run and manage vulnerability assessments on your databases.

1. Run a scan

The Scan For Vulnerabilities dialog allows you to specify the location where scans will be saved. You can leave the default location or click Browse. to save the scan results to a different location.

When you are ready to scan, select OK to scan your database for vulnerabilities.

The scan is lightweight and safe. It takes a few seconds to run, and is entirely read-only. It does not make any changes to your database.

2. View the report

When your scan is complete, your scan report is automatically displayed in the primary SSMS pane. The report presents an overview of your security state; how many issues were found, and their respective severities. Results include warnings on deviations from best practices, as well as a snapshot of your security-related settings, such as database principals and roles and their associated permissions. The scan report also provides a map of sensitive data discovered in your database, and includes recommendations of the built-in methods available to protect it.

3. Analyze the results and resolve issues

Review your results and determine which findings in the report are true security issues in your environment. Drill-down to each failed result to understand the impact of the finding, and why each security check failed. Use the actionable remediation information provided by the report to resolve the issue.

4. Set your Baseline

As you review your assessment results, you can mark specific results as being an acceptable Baseline in your environment. The baseline is essentially a customization of how the results are reported. Results that match the baseline are considered as passing in subsequent scans.

Once you have established your baseline security state, VA only reports on deviations from the baseline, and you can focus your attention on the relevant issues.

5. Run a new scan to see your customized tracking report

After you complete setting up your Rule Baselines, run a new scan to view the customized report. VA now reports only failing security issues that deviate from your approved baseline state.

6. Open a previously run scan

You can also open an existing scan result via the File->Open menu. Select Vulnerability Assessment. and open the scans directory to find the scan result you wish to view.

VA can now be used to monitor that your databases maintain a high level of security at all times, and that your organizational policies are met. If compliance reports are required, VA reports can be helpful to facilitate the compliance process.

Manage vulnerability assessments using PowerShell

You can use PowerShell cmdlets to programmatically manage vulnerability assessments for your SQL Servers. The cmdlets can be used to run assessments programmatically, export the results and manage baselines. To get started, download the latest SqlServer PowerShell module from the PowerShell Gallery site. You can learn more here.

Vulnerability Assessment

What Is Vulnerability Assessment?

Vulnerability assessment is an evaluation method that enables organizations to review their systems for potential security weaknesses. It performs a vulnerability analysis process that aims to discover whether the organization is at risk of known vulnerabilities, assigns a level of severity to those vulnerabilities, and recommends whether a threat should be mitigated or remediated.

Vulnerability testing helps organizations discover whether their systems and software have active default settings that are insecure, which can include easily guessable admin passwords. It also assesses vulnerability to code injection attacks, such as Structured Query Language injection (SQLi) and cross-site scripting (XSS) attacks, and checks for a potential escalation of user privileges or incorrect authentication mechanisms.

Types of Vulnerability Assessments

The most common types of vulnerability assessments that organizations deploy are:

4 Steps of Vulnerability Assessment

Organizations that undergo a vulnerability assessment will follow a four-step process.

However, it is important to remember that a vulnerability assessment is not a one-off activity that organizations forget about when it has been completed. It must be repeated regularly and operationalized by encouraging development, security, and operations teams to cooperate closely with each other—a process called DevSecOps.

Vulnerability Identification

The first step is to create a comprehensive list of vulnerabilities in an organization’s applications, servers, and systems. This is done by either scanning them using specific internet vulnerability assessment tools or by testing them manually. Vulnerability analysts can also use vulnerability databases, vendor announcements, threat intelligence feeds, and asset management systems to identify potential weaknesses.

This first step of the process helps organizations understand the full details. This includes elements like risk appetite and tolerance level, business impact analysis, mitigation practices and policies, countermeasures for devices and services, and residual risk treatment.

Vulnerability Analysis

The second step aims to discover the source and initial cause of the vulnerabilities identified in the first step. The analysis stage identifies the system components responsible for each vulnerability as well as its root cause.

Remediation

The final step in the vulnerability assessment process is to close any security gaps. This is usually a joint effort between the DevSecOps team, which sets out the most effective way to mitigate or remediate each vulnerability discovered. The remediation process includes introducing new cybersecurity measures, procedures, or tools; updating configuration and operational changes; and developing or implementing patches for identified vulnerabilities.

With the process completed, it is also vital for organizations to create a vulnerability assessment report. This needs to include recommendations on how to correct and mitigate vulnerabilities, risk mitigation techniques, and any gaps the assessment uncovers between the results and the organization’s system baseline.

The report needs to include the name of the vulnerabilities, the date they were discovered, and the score attributed based on the Common Vulnerabilities and Exposures (CVE) database. It also needs to include a detailed description of vulnerabilities, systems affected, processes required to correct vulnerabilities, and a proof of concept of the vulnerability.

Vulnerability Assessment Tools

Organizations can discover new and known vulnerabilities through specific vulnerability assessment tools. They should schedule regular and automated scans of their critical IT systems, and ensure the results of the scans are fed into their ongoing vulnerability assessment operation.

One of the most popular tools for vulnerability assessments is a web application scanner, such as the Fortinet Web Vulnerability Scanner. These tools scan, test, and simulate attack patterns of known vulnerabilities.

Protocol scanners can also be used to assess vulnerabilities. These are specifically designed to search for vulnerable network services, ports, and cybersecurity protocols. The other most common tool for vulnerability assessment purposes is a network scanner, which can be used to visualize organizations’ networks. It is also useful for discovering warning signs of vulnerabilities, such as insecure Internet Protocol (IP) addresses and spoofed or suspicious packet activity.

In addition, organizations should consider using plugins within the vulnerability assessment platform, such as scans of common and popular ports, firewalls, and content management systems (CMS), such as Drupal, Joomla, and WordPress.

How Fortinet Can Help: Vulnerability Assessment and WAF

Fortinet protects organizations and their business-critical applications through its FortiWeb web application firewall (WAF), which was named a Challenger in the 2020 Gartner Magic Quadrant for WAFs. Fortinet WAFs provide web applications with protection against attacks that target both known and new, or unknown, vulnerabilities.

The FortiWeb WAFs are particularly crucial to protecting organizations in the face of the ever-evolving threat landscape. Every time organizations deploy new web application features, update existing features, or expose new application programming interfaces (APIs), their attack surface expands. FortiWeb keeps pace with the expanding threat landscape, ensuring organizations are always protected through advanced features that defend them against known and zero-day threats.

FortiWeb uses an advanced and multi-layered approach that provides protection against high-risk threats, such as the Open Web Application Security Project (OWASP) Top 10. It also uses machine learning to customize protection for each application and ensure robust protection without the time-consuming manual modifications that other solutions require.

This enables the identification of anomalous, benign, and malicious behavior, as well as the capability to block malicious bot activity.

FortiWeb protects business applications wherever they are hosted, with options for hardware appliances, containers, cloud environments, Software-as-a-Service (SaaS) solutions, and virtual machines.
