Which type of attack is carried out by threat actors against a network to determine which IP addresses, protocols, and ports are allowed by ACLs?

  • social engineering
  • denial of service
  • phishing
  • reconnaissance

Explanation: Packet filtering ACLs use rules to filter incoming and outgoing traffic. These rules are defined by specifying IP addresses, port numbers, and protocols to be matched. Threat actors can use a reconnaissance attack involving port scanning or penetration testing to determine which IP addresses, protocols, and ports are allowed by ACLs.
