27
Q

Is a solution that evolved from the OpenDNS acquisition. This is a cloud delivered solution that blocks malicious destination using DNS

A

Cisco Umbrella

28
Q

Umbrella looks at the patterns of DNS requests from devices and uses them to detect the following:

A
  • compromised systems
  • command-and-control callbacks
  • malware and phishing attempts
  • algorithm-generated domains
  • domain co-occurences
  • newly registered domains
  • malicious traffic and payloads that never reach the target
29
Q

A

Anycast IP routing

30
Q

Umbrella uses authoritive DNS logs to find the following

Q

Is a DNS technique used by botnets to hid phisihing and malware delivery sites behid an ever changing network of compromised hosts acting as proxies

A

Fast Flux

32
Q

Machine learning and advanced algorithms are used heavily to find and automatically block malicious domains.

A
  • co-occurrence model (this model identifies domains required right before or after a given domain)
  • Traffic spike model: (this model recognizes when spike in traffic to a domain match patterns seen with other attacks)
  • Predictive IP space monitoring model ( this model starts with domain identified by the spike rank model and scores the steps attackers take to set up infrastructure)
33
Q
