What are the top TCP/IP security threats in a hybrid cloud environment?

1 Spoofing attacks

Spoofing attacks are when an attacker pretends to be a legitimate source or destination of network traffic by altering the IP or MAC address, port number, or sequence number of a packet. This can allow the attacker to bypass authentication, gain unauthorized access, steal data, or disrupt services. For example, an attacker can spoof the IP address of a public cloud server to trick an on-premises client into sending sensitive information. To prevent spoofing attacks, you should use encryption, authentication, and filtering techniques to verify the identity and integrity of network packets.

3 DoS attacks

DoS attacks are when an attacker overwhelms a network resource with excessive or malicious traffic to degrade its performance or availability. This can disrupt normal operations, cause downtime, or consume bandwidth. For example, an attacker can launch a DoS attack against a public cloud service that is connected to an on-premises network to prevent legitimate users from accessing it. To prevent DoS attacks, you should use monitoring, throttling, and filtering techniques to detect and block abnormal or unwanted traffic.

4 Man-in-the-middle attacks

Man-in-the-middle attacks are when an attacker inserts himself between two communicating parties and alters or relays their messages. This can compromise the integrity, authenticity, or confidentiality of network communication. For example, an attacker can perform a man-in-the-middle attack between an on-premises server and a public cloud service to modify or steal data. To prevent man-in-the-middle attacks, you should use encryption, authentication, and verification techniques to secure and validate network communication.
