Langkah pengamanan jaringan LAN yang terhubung ke internet dapat dilakukan dengan cara ...
- A.
A. konfigurasi sistem Firewall dan Proxy yang tepat pada router/server gateway
- B.
B. memberikan password pada OS server/gateway
- C.
C. menggunakan password pada router
- D.
D. menginstall antivirus pada komputer client
- E.
E. menggunakan sistem operasi Linux
Correct Answer
A. A. konfigurasi sistem Firewall dan Proxy yang tepat pada router/server gatewayExplanation
The correct answer is A. Configuring the Firewall and Proxy system correctly on the router/server gateway. This is the most effective way to secure a LAN network connected to the internet. A firewall acts as a barrier between the LAN and the external network, monitoring and controlling incoming and outgoing network traffic. It can block unauthorized access and filter out potentially harmful data. A proxy server can enhance security by acting as an intermediary between the LAN and the internet, filtering and caching web content, and providing an additional layer of protection.Rate this question:

Pengamanan akses file yang berlaku ketika diakses dari jaringan / komputer lain di jaringan ....
- A.
A. Shared Permission
- B.
B. Security Permission
- C.
C. Disk Permission
- D.
D. Folder permission
- E.
E. Open permission
Correct Answer
A. A. Shared PermissionExplanation
Shared permission refers to the access control settings that determine the level of access granted to a file or folder when it is accessed from another computer or network. It allows multiple users or computers to access and modify the file or folder simultaneously, while also providing options to restrict or limit certain actions. This ensures that only authorized individuals or systems can access and manipulate the file or folder, maintaining security and preventing unauthorized access or modifications.Rate this question:

- E.
E. ~# iptables –A FORWARD –p tcp –dport 80 –j ACCEPT –-to-port 8080
Correct Answer
C. C. ~# iptables –t nat –A POSTROUTING –o eth0 –j MASQUERADEExplanation
The correct answer is C because it uses the correct syntax and options for configuring a Linux server to perform NAT and act as an internet gateway. The "-t nat" option specifies the nat table, which is used for network address translation. The "-A POSTROUTING" option appends a rule to the POSTROUTING chain, which is used for packets that are being forwarded and leaving the server. The "-o eth0" option specifies the outgoing interface, and the "-j MASQUERADE" option tells iptables to perform network address translation on the packets.Rate this question:

Memberikan userid dan password kepada orang yang paling kita percayai
- D.
Tidak ada jawaban yang benar
Correct Answer
C. Memberikan userid dan password kepada orang yang paling kita percayaiExplanation
The given answer, "Memberikan userid dan password kepada orang yang paling kita percayai" (Giving userid and password to the person we trust the most), is not a valid effort to mitigate risk in a network system. Sharing sensitive login credentials with someone, even if they are trusted, increases the vulnerability of the system and can lead to unauthorized access or misuse of information. Therefore, this option does not help in addressing or reducing risk in the network system.Rate this question:

Security mechanism yang digunakan untuk menghindari ancaman network sniffing adalah:
- A.
Password
- B.
Antivirus
- C.
Encryption
- D.
Digital signature
Correct Answer
C. EncryptionExplanation
Encryption is the security mechanism used to prevent network sniffing threats. It involves converting plaintext data into ciphertext using an encryption algorithm and a secret key. This ensures that even if an attacker intercepts the network traffic, they cannot understand the information without the key to decrypt it. Encryption provides confidentiality and protects sensitive data from being accessed or understood by unauthorized individuals.Rate this question:

Sebuah security policy menyatakan bahwa folder penyimpanan file harus dalam status read-only. Security mechanism yang memastikan policy ini dilaksanakan adalah:
- A.
File permission system
- B.
Folder backup system
- C.
File encryption application
- D.
Automatic antivirus update
Correct Answer
A. File permission systemExplanation
The correct answer is the File permission system. This security mechanism ensures that the folder storing files is set to read-only status, preventing any unauthorized modifications or deletions. By setting appropriate file permissions, the system can control access to the folder and ensure that only authorized users have the necessary privileges to make changes. This helps enforce the security policy stated in the question. Folder backup system, file encryption application, and automatic antivirus update are not directly related to enforcing read-only status on the folder.Rate this question:
