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?
- phishing
- reconnaissance
- denial of service
- social engineering
| Answers Explanation & Hints:
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. |
