Untuk menghindari eksploitasi lubang keamanan dengan teknik Buffer Overflow, programmer harus melakukan ….
-
Corrupt array checking
-
Insufficient bound checking
-
String concatenation checking
-
Source code debugging
Correct Answer
A. Insufficient bound checkingExplanation
Insufficient bound checking refers to the practice of not properly validating the size or length of input data before storing it in a buffer. This can lead to buffer overflow vulnerabilities, where an attacker can overwrite adjacent memory locations and potentially execute malicious code. To avoid this, programmers need to ensure that they validate and limit the size of input data to prevent buffer overflows and potential exploitation.Rate this question:

-
MAC ID Filtering
-
Static IP Addressing
-
Stop SSID Broadcasting
-
Using WEP
Correct Answer
A. Stop SSID BroadcastingExplanation
Stop SSID Broadcasting is a technique that can be used to minimize security threats by preventing the wireless network name from being detected by other devices. By disabling SSID broadcasting, the network becomes "hidden" and only devices that already know the network name can connect to it. This adds an extra layer of security as it makes it more difficult for unauthorized users to discover and attempt to access the network.Rate this question:

RF Shielding
Correct Answer
A. RF ShieldingExplanation
RF Shielding is a technique that can be used to prevent wireless signals from being used outside of the office building. It involves creating a physical barrier or shield around the area to block the signals from escaping. This can be done using materials that are designed to absorb or reflect the radio waves, effectively preventing them from reaching beyond the designated area. By implementing RF shielding, Jenni can ensure that the wireless signals managed by her cannot be accessed or utilized outside of her office building.Rate this question:

Dalam model OSI, enkripsi WEP bekerja pada layer ….
-
Physical
-
Data link
-
Network
-
Transport
Correct Answer
A. Data linkExplanation
The correct answer is "Data link." In the OSI model, the data link layer is responsible for the reliable transfer of data between two nodes on a network. It provides error detection and correction, as well as flow control. WEP (Wired Equivalent Privacy) is a security protocol that operates at the data link layer, providing encryption and authentication for wireless networks. Therefore, WEP works at the data link layer in the OSI model.Rate this question:

Dalam proses enkripsi WEP, operasi logika yang diterapkan antara bit stream keluaran RC4 dengan plaintext adalah ….
-
NOT
-
AND
-
OR
-
XOR
Correct Answer
A. XORExplanation
In the process of WEP encryption, the logical operation applied between the output bit stream of RC4 and the plaintext is XOR. XOR (exclusive OR) operation combines the bits from both inputs and produces an output where each bit is set if the corresponding bits in the inputs are different. This operation is commonly used in encryption algorithms to ensure that the encrypted data is secure and can only be decrypted using the correct key.Rate this question:

Salah satu kelemahan teknik enkripsi WEP dalam hal password adalah ….
-
Menggunakan public-key
-
Menggunakan shared-key
-
Menggunakan private-key
-
Menggunakan secret-key
Correct Answer
A. Menggunakan shared-keyExplanation
The weakness of WEP encryption technique in terms of password lies in using a shared-key. This means that the same key is shared among multiple users or devices, making it easier for an attacker to intercept and guess the password. This lack of uniqueness and randomness in the shared-key makes it vulnerable to brute-force attacks and increases the likelihood of unauthorized access to the encrypted data.Rate this question:
