Configured Wiz Branch Policies

Wiz employs a set of pre-configured policies to assess various aspects of your codebase and infrastructure. These policies are designed to detect vulnerabilities, secrets, misconfigurations, and sensitive data exposure. Let's take a closer look at the policies typically configured for a 'master' branch scan:

• Default Vulnerabilities Policy: This policy focuses on identifying known vulnerabilities in your dependencies and application code. It ensures that your systems are not susceptible to exploits that could compromise your environment. The importance of this policy cannot be overstated, as vulnerabilities are a primary entry point for attackers. Regularly scanning for and addressing vulnerabilities is a crucial step in maintaining a strong security posture. This policy often includes checks against common vulnerability databases and may also incorporate proprietary threat intelligence feeds to stay ahead of emerging threats. Furthermore, the policy may prioritize vulnerabilities based on their severity and exploitability, allowing security teams to focus on the most critical issues first.

• Default Secrets Policy: The secrets policy is designed to detect inadvertently exposed credentials, API keys, and other sensitive information within your codebase. Protecting secrets is crucial to prevent unauthorized access and potential breaches. The ramifications of exposed secrets can be severe, leading to data leaks, service disruptions, and reputational damage. This policy typically employs a combination of pattern matching, entropy analysis, and context-aware detection techniques to identify secrets with high accuracy. It is essential to implement this policy rigorously, as secrets can easily be overlooked during development and deployment processes.

• Secrets-Scan-Policy: This policy is a more specialized version of the default secrets policy, often tailored to specific organizational needs or compliance requirements. It may include custom rules and detection patterns to identify secrets unique to your environment. The flexibility of this policy allows security teams to adapt to evolving threat landscapes and specific security concerns. For example, it can be configured to scan for specific types of credentials or API keys used within the organization. This policy is a valuable tool for ensuring comprehensive secrets management and reducing the risk of exposure.

• Default IaC Policy: Infrastructure as Code (IaC) allows you to manage and provision your infrastructure through code, enabling automation and consistency. However, misconfigurations in IaC can lead to security vulnerabilities. The Default IaC policy scans your IaC templates (e.g., Terraform, CloudFormation) for misconfigurations that could expose your infrastructure to risks. Addressing these misconfigurations early in the development lifecycle is essential for preventing costly security incidents. This policy typically checks for common misconfiguration patterns, such as overly permissive security groups, exposed storage buckets, and insecure resource configurations. By identifying these issues proactively, organizations can ensure that their infrastructure is deployed securely and in compliance with best practices.

• Default Sensitive Data Policy: This policy focuses on identifying sensitive data, such as personally identifiable information (PII) or financial data, that may be inadvertently stored in your codebase or configuration files. Protecting sensitive data is a legal and ethical imperative, and this policy helps ensure compliance with data privacy regulations. The policy often uses regular expressions, data dictionaries, and machine learning techniques to identify sensitive data with high accuracy. It is essential to implement this policy to prevent data breaches and maintain customer trust. Furthermore, the policy may be configured to redact or mask sensitive data, reducing the risk of exposure.

• Default SAST Policy (Wiz CI/CD scan): Static Application Security Testing (SAST) involves analyzing your source code for security vulnerabilities without executing the code. This policy integrates with your Continuous Integration/Continuous Deployment (CI/CD) pipeline to identify vulnerabilities early in the development process. By catching security issues early, you can reduce the cost and effort required to remediate them. This policy typically includes a range of static analysis techniques, such as data flow analysis, control flow analysis, and taint analysis, to identify potential vulnerabilities. It is a valuable tool for ensuring that your applications are built securely from the ground up.

Wiz Scan Summary: Key Findings and Analysis

The Wiz scan summary provides a high-level overview of the findings across different categories. This summary is crucial for understanding the overall security posture of your 'master' branch and prioritizing remediation efforts. Here's a breakdown of the typical findings:

• Vulnerabilities: This section reports the number of known vulnerabilities detected in your codebase and dependencies. A high number of vulnerabilities indicates a potential area of concern that requires immediate attention. It's important to investigate each vulnerability, assess its severity, and apply the necessary patches or workarounds. The Wiz scan summary typically provides links to detailed reports that include information about the vulnerability, its impact, and recommended remediation steps.

• Sensitive Data: This section highlights instances of sensitive data found within your codebase. Exposure of sensitive data can have severe consequences, including legal and financial repercussions. It's crucial to identify and remediate these findings promptly. This often involves removing the sensitive data from the codebase, implementing access controls, and ensuring that data is encrypted both in transit and at rest. The Wiz scan summary may also provide information about the type of sensitive data detected, its location, and the potential impact of its exposure.

• Secrets: The secrets section reports the number of exposed credentials, API keys, and other sensitive secrets found in your codebase. Exposed secrets can be exploited by attackers to gain unauthorized access to your systems and data. It's essential to revoke and rotate any exposed secrets immediately. This section often provides details about the type of secret, its location, and the resources it grants access to. Additionally, it may recommend implementing secrets management practices, such as using a vault or secrets management tool, to prevent future exposures.

• IaC Misconfigurations: Infrastructure as Code (IaC) misconfigurations can lead to security vulnerabilities and compliance issues. This section reports the number of misconfigurations detected in your IaC templates. Addressing these misconfigurations is crucial for ensuring the security and stability of your infrastructure. The severity levels (High, Medium, Low) indicate the potential impact of the misconfiguration. High-severity misconfigurations typically represent critical risks that require immediate remediation, while medium- and low-severity misconfigurations may be addressed in a more planned manner. The Wiz scan summary often provides detailed information about each misconfiguration, its potential impact, and recommended remediation steps.

  • Example Scenario: In the provided scan summary, there is one High-severity IaC misconfiguration, seven Medium-severity misconfigurations, and three Low-severity misconfigurations. This indicates that there are critical issues that need to be addressed immediately to prevent potential security breaches. It is essential to prioritize the high-severity misconfiguration and investigate the medium- and low-severity issues to prevent them from being exploited. Addressing these misconfigurations proactively can significantly reduce the risk of security incidents and improve the overall security posture of your infrastructure. The scan summary may also provide information about the specific IaC templates affected by the misconfigurations, allowing security teams to focus their remediation efforts effectively.
