Domain Generation Algorithms (DGA) Prevention

Question 1

Juniper Firewalls can utilize domain reputation services to block access to domains generated by DGAs based on known malicious patterns, preventing communication with command and control servers.

Answer 1

Domain Reputation Services

Question 2

Juniper Firewalls with behavior-based analysis can detect abnormal domain name resolution patterns indicative of DGA activity, triggering alerts or blocking actions.

Answer 2

Behavior-Based Analysis

Question 3

IDS/IPS features can identify and block DGA-related traffic by detecting known DGA algorithms or behavior associated with DGA-based malware.

Answer 3

Intrusion Detection and Prevention System (IDS/IPS)

Question 4

Juniper Firewalls can integrate threat intelligence feeds that provide updated information about malicious domains generated by DGAs, enabling proactive blocking.

Answer 4

Threat Intelligence Feeds

Question 5

Juniper Firewalls can implement DNS sinkholing to redirect traffic from DGA-generated domains to a controlled server, preventing malware from establishing a connection.

Answer 5

DNS Sinkholing
