The Urgent Plea to Fix Misconfiguration Errors in Network Defenses

Cybersecurity Agencies Highlight Top 10 Network Configuration vulnerabilities

The National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have jointly called on network defenders to prioritize addressing easily exploitable misconfiguration errors that present significant vulnerabilities in organizations’ cybersecurity infrastructure. In a recent advisory, both agencies emphasized the urgent need for identifying and rectifying these common network configurations found to be frequently targeted by threat actors.

The Red and Blue teams, as well as incident response teams from both agencies, have identified the following as the top 10 most common network configuration vulnerabilities:

1. Default Configuration of Software and Applications

Default configurations of software and applications often have common access credentials or settings that are widely known. Failure to change these default settings upon installation provides easy access for threat actors. Network defenders must secure software and applications promptly after installation by modifying default configurations to unique, more complex settings.

2. Improper Separation of User/Administrator Privilege

The improper separation of user and administrator privileges is a common security mistake that allows attackers to gain unauthorized access to sensitive systems. Organizations must establish and enforce strong access control policies that clearly differentiate user and administrator privileges to mitigate the risk of misuse.

3. Insufficient Internal Network Monitoring

Lack of adequate internal network monitoring increases the chances of unauthorized access and lateral movement within an organization’s systems. Network defenders should implement robust network monitoring solutions and employ real-time analytics to promptly detect and respond to any malicious activities within their networks.

4. Lack of Network Segmentation

Absence or poor implementation of network segmentation makes it easier for attackers to move laterally inside an organization’s network once they have obtained initial access. Implementing proper network segmentation by dividing the network into segregated segments can help contain an attack and prevent lateral movement.

5. Poor Patch Management

Failure to keep software and systems up to date with the latest security patches leaves organizations exposed to known vulnerabilities that threat actors often exploit. Strong patch management practices, including timely deployment of patches and vulnerability assessments, are crucial to maintaining a secure network infrastructure.

6. Bypass of System Access Controls

Allowing users or systems to bypass access controls creates opportunities for unauthorized access and privilege escalation. Organizations must enforce strict access control policies and configurations that prevent any form of access bypass.

7. Weak or Misconfigured Multifactor Authentication (MFA) Methods

Multifactor Authentication (MFA) provides an additional layer of security by requiring users to provide multiple forms of authentication. Weak or improperly configured MFA methods reduce their effectiveness and make accounts more susceptible to compromise. Organizations should implement strong MFA methods and ensure proper configuration to enhance security.

8. Insufficient Access Control Lists (ACLs) on Network Shares and Services

Lack of proper access control lists (ACLs) on network shares and services can allow unauthorized users to gain access to privileged information. Organizations should regularly review and update ACLs to ensure only authorized individuals have access to sensitive resources.

9. Poor Credential Hygiene

Bad credential hygiene practices such as weak passwords, password reuse, and inadequate password expiration policies increase the risk of unauthorized access. Organizations should enforce robust password policies that include the use of strong and unique passwords, frequent password changes, and the implementation of password managers where possible.

10. Unrestricted Code Execution

Allowing code execution without sufficient restrictions exposes networks to potential exploitation by threat actors. Network defenders need to enforce strong controls on code execution by implementing secure coding practices, conducting regular code reviews, and leveraging automated tools to identify and mitigate vulnerabilities at the code level.

Secure-by-Design: A Call for Immediate Action

The joint advisory further emphasized the necessity for software providers to prioritize secure-by-design principles to prevent these and other misconfigurations. With cybersecurity threats constantly evolving, it is crucial for software providers to prioritize security from the initial development phase of their products. By integrating secure-by-design practices into software and application development lifecycles, providers can significantly reduce the opportunities for misconfigurations and vulnerabilities to occur.

Editorial: Strengthening Cybersecurity Requires Collective Effort

This advisory by the NSA and CISA serves as a stark reminder of the ever-present cybersecurity threats that organizations face. From government agencies to private enterprises, the need for continuous investment in proactive and robust cybersecurity measures is paramount.

While it is incumbent upon organizations to address and rectify the identified misconfigurations, it is imperative that software providers play their essential role in developing secure systems. By embracing secure-by-design principles, software providers can help reduce the burden on network defenders and minimize the potential for misconfigurations that expose organizations to cyberattacks.

Ensuring a Safer Digital Future

Protecting ourselves and our organizations from cyber threats is a collective responsibility. While the NSA and CISA provide invaluable guidance, individuals and organizations must remain vigilant and make cybersecurity a top priority. Implementing best practices, such as regular software updates, strong access controls, multi-factor authentication, and network monitoring, can significantly enhance an organization’s security posture.

Moreover, fostering a culture of cybersecurity awareness and education is vital. Organizations should invest in comprehensive training programs that enable employees to recognize and respond to potential threats effectively. By equipping individuals with the knowledge and skills needed to navigate the digital landscape safely, we can collectively build a more resilient and secure cyber environment.

In conclusion, the advisory issued by the NSA and CISA reinforces the urgent need for organizations to address common misconfiguration errors in their network defenses. By actively incorporating secure-by-design principles into software development and implementing best practices in access control, network monitoring, and patch management, organizations can significantly reduce their exposure to cyber threats. With a collective effort and a commitment to cybersecurity, we can build a safer digital future for all.
