A systems administrator is configuring network management but is concerned about confidentiality. Which of the following should the administrator configure to address this concern?
SNMPv3 (Simple Network Management Protocol version 3) includes built-in security features such as authentication and encryption, which help ensure confidentiality and integrity of the management data being transmitted. This is critical for protecting sensitive information in network management.
What are the three important services of SNMPv3 security model?
SNMPv3 protects against these threats by providing the security services of Data Integrity, Authentication, Privacy (Confidentiality), and Message Timeliness .
What does IPsec protect against?
IPsec is used for protecting sensitive data, such as financial transactions, medical records and corporate communications, as it's transmitted across the network. It's also used to secure virtual private networks (VPNs), where IPsec tunneling encrypts all data sent between two endpoints.
Pick your poison?
The question is about configuring network management but is concerned about confidentiality.
A. SNMPv3: Simple Network Management Protocol. v3 is encrypted. Gathers data(statistics) from agents running on other devices.
B. Community strings: Is a means of SNMP accessing statistics stored within a router or other device.
C. IPSec tunnels: encrypt all traffic in tunnel.
D. ACL: permissions to control access to resources.
SNMPv3 focuses on securing SNMP communication specifically, which may not cover other network communication within the same device. IPsec secures network communication at the IP layer, protecting all traffic between endpoints, not just specific protocols.
To address concerns about confidentiality in network management, the administrator should configure **SNMPv3 (Simple Network Management Protocol version 3)**. SNMPv3 provides authentication and encryption, ensuring the confidentiality and integrity of SNMP messages. It allows you to set up user authentication and access control, making it the most secure option among the ones listed.
So, the correct answer is **A. SNMPv3**.
IPSec (Internet Protocol Security) is a set of protocols that provide security for IP communications by authenticating and encrypting each IP packet in a communication session. By using IPSec tunnels, the administrator can secure the SNMP traffic between the management station and the managed devices, ensuring that the information being exchanged cannot be intercepted or tampered with by unauthorized parties.
SNMPv3 is a version of SNMP that provides more robust security features than previous versions, such as authentication and encryption, but it's not enough to secure the communication.
SNMPv3 (Simple Network Management Protocol version 3) offers comprehensive security features, including authentication, encryption, and access control. It supports message integrity through HMAC (Hash-based Message Authentication Code) and data encryption using protocols like AES (Advanced Encryption Standard). SNMPv3 is the most secure version of SNMP and is recommended for protecting the confidentiality of management data.
It is also the only option that has anything to do with network management.
