Anomaly-Based Intrusion Detection Systems (IDS):

Anomaly-based IDS monitor network traffic and system activities for unusual patterns that may indicate malicious behavior. They are effective in identifying unknown threats by detecting deviations from the established baseline of normal activities.

WEP is the type of wireless encryption employed by Charlie in the above scenario. Wireless encryption is a technique that involves encoding or scrambling the data transmitted over a wireless network to prevent unauthorized access or interception. Wireless encryption can use various algorithms or protocols to encrypt and decrypt the data, such as WEP, WPA, WPA2, etc. WEP (Wired Equivalent Privacy) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer . WEP can be used to provide basic security and privacy for wireless networks, but it can also be easily cracked or compromised by various attacks . In the scenario, Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN (Wireless Local Area Network). To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. This means that he employed WEP for this purpose. TKIP (Temporal Key Integrity Protocol) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer with dynamic keys . TKIP can be used to provide enhanced security and compatibility for wireless networks, but it can also be vulnerable to certain attacks . AES (Advanced Encryption Standard) is a type of wireless encryption that uses the Rijndael algorithm to encrypt information in the data link layer with fixed keys . AES can be used to provide strong security and performance for wireless networks, but it can also require more processing power and resources . CCMP (Counter Mode with Cipher Block Chaining Message Authentication CodeProtocol) is a type of wireless encryption that uses the AES algorithm to encrypt information in the data link layer with dynamic keys . CCMP can be used to provide robust security and reliability for wireless networks, but it can also require more processing power and resources

To analyze the IoT network traffic capture and identify the command sent to IoT devices, follow these steps:

Open the Capture File:

Use a network analysis tool like Wireshark to open theIoT_capture.pcapngfile.

Filter and Analyze:

Apply appropriate filters to isolate relevant traffic. Look for command patterns typically sent to IoT devices.

Identify the Command:

Upon analyzing the captured traffic, the commandForest_Fire_Alert444is identified as the one sent over the network to IoT devices during the attack.
