ARP Spoofing & Poisoning Prevention

Question 1

Juniper Firewalls can perform ARP inspection to monitor ARP traffic within the network. They can detect and block ARP spoofing attempts by comparing ARP requests and responses to identify discrepancies.

Answer 1

ARP Inspection

Question 2

Juniper Firewalls can implement MAC address filtering policies to control which MAC addresses are allowed to communicate with specific IP addresses. This prevents unauthorized associations.

Answer 2

MAC Address Filtering

Question 3

Juniper Firewalls can enforce port security policies that restrict the number of MAC addresses allowed on a specific port. This prevents attackers from connecting multiple devices to a single port.

Answer 3

Port Security

Question 4

Juniper Firewalls with behavior-based analysis can detect abnormal ARP traffic patterns, such as a single device sending excessive ARP requests. They can trigger alerts or block suspicious activities.

Answer 4

Behavior-Based Analysis

Question 5

Juniper Firewalls can enforce access control policies that restrict ARP traffic to trusted devices and prevent external devices from participating in ARP communication.

Answer 5

Access Control Policies
