Option 1: This option states that secret data is illegally distributed through computer networks in IP spoofing. However, this is not an accurate explanation of IP spoofing. IP spoofing is a technique used by cyber criminals or attackers to disguise their true identity by forging the source IP address in a network packet. It does not necessarily involve the distribution of secret data.

Option 2: This option correctly explains IP spoofing. It states that cyber criminals attack another computer by identifying the electronic identity of a trusted machine, and then pretend to be that machine by spoofing their true electronic identity. In other words, they deceive the target computer into thinking that the attack is coming from a trusted source.

Option 3: This option is not related to IP spoofing. It mentions the use of cryptographic and steganographic algorithms for achieving data confidentiality. While these techniques are important for securing data, they do not directly relate to IP spoofing.

Option 4: This option mentions the identification of cyber terrorists, cyber fraud, or cyber crimes. While these are important concepts in the field of cybersecurity, they are not directly associated with IP spoofing.

In conclusion, option 2 is the correct explanation of IP spoofing as it accurately describes the technique used by cyber criminals to deceive a
