DNS Tunneling Prevention

Question 1

Juniper Firewalls can inspect DNS traffic and apply filtering policies. They can block or flag DNS requests that exhibit suspicious patterns indicative of tunneling, such as unusually long queries or non-standard ports.

Answer 1

DNS Inspection and Filtering

Question 2

Juniper Firewalls with behavior-based analysis can monitor DNS traffic for unusual behavior, such as a high volume of DNS queries or patterns consistent with tunneling. They can trigger alerts or block suspicious activities.

Answer 2

Behavior-Based Analysis

Question 3

IDS/IPS capabilities in Juniper Firewalls can detect and alert on DNS tunneling attempts. They can identify and block DNS queries associated with tunneling techniques.

Answer 3

Intrusion Detection/Prevention System (IDS/IPS)

Question 4

Integrating Juniper Firewalls with threat intelligence feeds provides timely information on known DNS tunneling domains and tactics. This allows the firewall to block access to malicious resources.

Answer 4

Threat Intelligence Integration

Question 5

Juniper Firewalls can employ application control policies to restrict or block applications and protocols known to be used in DNS tunneling. This prevents their use.

Answer 5

Application Control
