Exam SY0-701 topic 1 question 601 discussion

Before configuring ports, permissions or network rules, it is essential to ensure that the system is up to date, including with the latest version of the operating system, which corrects known vulnerabilities.

Correct Answer: A Explanation Explanation/Reference: The first step in securing a newly deployed server is to close unnecessary service ports. Open ports can expose the server to unauthorized access and potential cyber threats. By closing unused ports, the attack surface is reduced, limiting the number of entry points available to attackers. Updating the software version (B) and upgrading the OS version (D) are important security measures but should follow the step of securing open ports to prevent immediate exposure to threats. Adding the device to the Access Control List (ACL) (C) is a step in network security but does not directly secure the server itself against potential attacks. Closing unnecessary ports helps in minimizing the risk of network-based attacks, such as port scanning and exploitation of default services.

chat gpt : A. Close unnecessary service ports. Explanation: When securing a newly deployed server, the first step is to reduce the attack surface. That starts with: Closing unnecessary service ports to prevent unauthorized access. Disabling unused services limits potential entry points for attackers. Why not the others first? B. Update the current version of the software – Important, but not as immediate as stopping exposure to the network. C. Add the device to the ACL – That’s part of network policy configuration, but not directly securing the server itself. D. Upgrade the OS version – Upgrades can introduce instability if not tested, and should follow securing the system.

GPT: The first step in securing a newly deployed server is to minimize its attack surface—and that starts with closing unnecessary service ports. Open ports expose services that could be exploited by attackers. By disabling unused services and ports: You reduce entry points for attacks. You limit exposure to only essential services.

Updating the software ensures you have the latest security patches and fixes for known vulnerabilities, which is crucial for protecting your server from potential attacks right from the start.
