Top 10 Cybersecurity Misconfigurations and Their Remedies
In the realm of cybersecurity, a slight misconfiguration can be the gateway for adversaries. This post delineates the top 10 misconfigurations as identified by security agencies and provides viable solutions to amend them, ensuring a robust security posture.
| Misconfiguration | Solution |
| Default configurations of software and applications | Configure software and applications with secure default settings. Disable unnecessary features and services. |
| Improper separation of user/administrator privilege | Implement proper access control mechanisms to separate user and administrator privileges. Use the principle of least privilege. |
| Insufficient internal network monitoring | Deploy robust network monitoring tools and technologies to detect and respond to internal threats. Implement intrusion detection and prevention systems. |
| Lack of network segmentation | Implement network segmentation to isolate critical systems and limit the impact of a breach. Use firewalls and VLANs to separate network segments. |
| Poor patch management | Establish a comprehensive patch management program to regularly update and apply security patches to all systems and software. |
| Bypass of system access controls | Strengthen system access controls by implementing multi-factor authentication and strong password policies. Regularly review and audit access controls. |
| Weak or misconfigured multifactor authentication (MFA) methods | Implement strong and properly configured MFA methods, such as biometrics or hardware tokens. Regularly review and update MFA configurations. |
| Insufficient access control lists (ACLs) on network shares and services | Implement proper access control lists (ACLs) to restrict access to network shares and services. Regularly review and update ACL configurations. |
| Poor credential hygiene | Enforce strong password policies, including regular password changes and the use of complex passwords. Educate users about password hygiene and the risks of password reuse. |
| Unrestricted code execution | Implement secure coding practices and perform code reviews to prevent unrestricted code execution vulnerabilities. Regularly update and patch software libraries and frameworks. |
By addressing these common misconfigurations and adhering to the prescribed solutions, organizations can significantly mitigate risks, ensuring a safer and more resilient infrastructure. For further guidelines, the advisory AA23-278A from CISA provides more in-depth information.
