Check Point Certified Security Administrator (CCSA) Practice Exam

Which protocol is primarily used for secure access to network devices remotely?

1. FTP

2. SSH

3. Telnet

4. HTTP

The correct answer is: SSH

The protocol primarily used for secure access to network devices remotely is SSH, which stands for Secure Shell. SSH provides a secure channel over an unsecured network by using cryptographic techniques, ensuring that the data transmitted is encrypted and secure from eavesdropping or tampering. This makes SSH the preferred choice for administrators who need to manage network devices securely. In contrast, protocols like Telnet do not provide any encryption, which means that data, including login credentials, can be intercepted in plain text. While Telnet can establish remote connections, it does so without security, making it vulnerable to attacks. FTP is another protocol listed, which is primarily used for transferring files. Like Telnet, FTP does not encrypt the data being sent, making it unsuitable for secure remote access. There is a secure version called SFTP, but standard FTP itself lacks the necessary security features. Similarly, HTTP is a protocol used for transferring hypertext across the web. While it plays a critical role in web communication, it also does not provide any encryption for data in transit. The secure version, HTTPS, does encrypt data but is not used for remote access to network devices. Thus, SSH stands out as the correct answer because it is specifically designed to facilitate secure remote connections, effectively
