Understanding how these tools work and how to use them properly is essential for maintaining cybersecurity. A. Construct a basic model of how an Intrusion Detection System (IDS) 5+5 CLO3 works. B. Identify the steps required to use antivirus software effectively. 3. Encryption is widely used to protect sensitive information during data transmission. In symmetric encryption, the same key is used to convert plaintext into ciphertext and back again. However, despite using such techniques, organizations still face several challenges in ensuring effective data protection. A. The plaintext “ALICE” is encrypted using a symmetric encryption 5+5 CLO3 method, and the ciphertext is “PLN”. Applying the same encryption method, encrypt your own name. B. Identify the challenges in data protection.
