Using the example below provide information with the Inline Antivirus above instead of Router Access Control

1. Router Access Control

Routers can be configured to prevent unauthorized users from gaining access to network resources. Router access controls are familiar to even novice information technology users. For example, the need to log onto a Wi-Fi network is an example of a router access control.

Some of the components of router access controls include:

User authentication. To gain access to network resources, users must authenticate by entering a user name and password, and possibly other elements of multifactor authentication. Vulnerabilities to this control include the potential for weak passwords, or poor user management of credential information. Insider threats are also a potential weakness affecting user authentication.

Approved access lists. Routers may be configured to only allow preapproved devices or IP addresses to have access to the router and network resources. Approved access may also restrict traffic based on traffic type, allowed ports, or other criteria. Device loss or theft is a potential weakness of approved access lists.

Firewalls. Network firewalls can protect networks from unauthorized access. Firewalls may also block specified traffic types. Potential weaknesses associated with Firewalls include Zero Day vulnerabilities associated with firewall firmware, firewall misconfigurations, poorly configured IoT devices, or SQL injection attacks.

VPNs. Virtual private networks provide another method of access control. VPNs allow authorized users that are not directly located connections on an organizations network to securely access network resources over public networks. Weaknesses associated with VPNs include an expanded attack surface, the potential for compromised credentials, and the potential for excessive network access, if VPNs are not constrained through an underlying Zero Trust architecture.

In summary, router access controls are an essential element of network security. However, like all security measures, vulnerabilities persist.
