Top 10 Cybersecurity Misconfigurations

Cybersecurity misconfigurations typically arise from incorrect settings, permissions or configurations within an organization’s IT infrastructure and security systems.

One significant consequence of misconfigurations is a heightened vulnerability to cyberattacks. When systems and software are not correctly configured, they can expose sensitive data or create security gaps that malicious actors exploit, resulting in data breaches, financial losses and reputational damage.

Misconfigurations can also lead to operational disruptions. Incorrectly configured security tools or firewalls, for instance, might block legitimate user access, causing service outages, productivity losses and customer dissatisfaction.

Rectifying these misconfigurations can be time-consuming and resource-intensive, diverting IT personnel from strategic tasks and resources from business objectives. Sometimes, it may take considerable time to detect misconfigurations, leaving the organization exposed to threats for extended periods.

NSA and CISA Identify the Top 10 Misconfigurations

The National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) recently released a joint advisory highlighting the 10 most common cybersecurity misconfigurations in large organizations. They include:

  1. Software and application default configurations
  2. Incorrect separation of user and administrator privilege
  3. Inadequate internal network monitoring
  4. Failure to segment networks
  5. Poor patch management practices
  6. Circumvention of system access controls
  7. Flawed multifactor authentication implementation
  8. Insufficient access control lists
  9. Poor credential practices
  10. Uncontrolled code execution

To address these misconfigurations, the agencies provide enterprise security teams with a detailed list of mitigation strategies. Highlights include:

  • Harden configurations and remove default credentials
  • Turn off unused services and enable access controls
  • Ensure software is updated regularly, and patching is automated
  • Audit, restrict and monitor administrative privileges and accounts

In addition to applying mitigations, the agencies advise enterprises to exercise, test and validate their security program against the threats mapped to the MITRE ATT&CK for Enterprise framework.

Benefits of Mitigating Misconfigurations

Mitigating cybersecurity misconfigurations provides many benefits to organizations. First, it enhances overall security posture. By addressing misconfigurations promptly, an organization reduces its attack surface and minimizes vulnerabilities that cybercriminals could exploit. This proactive approach helps safeguard sensitive data, maintain business continuity, and prevent financial and reputational damage that can result from data breaches and cyberattacks. Furthermore, when organizations implement effective configuration management practices, they can better adhere to compliance requirements, avoiding potential legal repercussions and financial penalties.

Second, mitigating cybersecurity misconfigurations results in improved operational efficiency. By reducing the occurrence of misconfigurations, organizations can decrease the likelihood of system downtime and service disruptions. This translates to higher productivity, reduced business interruption and enhanced customer satisfaction. Additionally, it frees up IT resources that might otherwise be tied up in identifying and rectifying misconfigurations, enabling IT teams to focus on strategic initiatives and innovation.
