SY0-701 Exam Dumps - CompTIA Security+ Exam 2025

SASE stands for Secure Access Service Edge. It is a cloud-based service that combines network and security functions into a single integrated solution. SASE can help reduce traffic on the VPN and internet circuit by providing secure and optimized access to the data center and cloud applications for remote employees. SASE can also monitor and enforce security policies on the remote employee internet traffic, regardless of their location or device. SASE can offer benefits such as lower costs, improved performance, scalability, and flexibility compared to traditional VPN solutions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457-458 1

Detailed Explanation:This scenario highlights the need for training on the secure use of removable media. Users should learn to avoid using untrusted external storage devices to prevent malware infections. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Removable Media Controls and User Awareness Training"​​.

The presence of another device providing internet access that bypasses the content filtering system indicates the existence of a rogue access point. Rogue access points are unauthorized devices that can create a backdoor into the network, allowing users to bypass security controls like content filtering. This presents a significant security risk as it can expose the network to unauthorized access and potential data breaches.

CompTIA Security+ SY0-701 Course Content: Rogue access points are highlighted as a major security risk, allowing unauthorized access to the network and bypassing security measures​​.

Automated vulnerability scanningis thefirst step in identifying system weaknesses. These scans systematically check for outdated software, misconfigurations, and known vulnerabilities in a network.

Penetration testing (B)is conducted after vulnerabilities are identified.

Threat hunting (C)focuses on detecting unknown threats, not listing vulnerabilities.

Comprehensive and Detailed In-Depth Explanation:

The first step in securing a newly deployed server is toclose 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)andupgrading 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 asport scanning and exploitation of default services.

A host-based firewall controls incoming and outgoing network traffic on a device by enforcing security rules, effectively blocking unwanted or insecure communications. It is specifically designed to protect the device from unauthorized access and malicious traffic.

System hardening (A) reduces vulnerabilities by disabling unnecessary services and patching but does not control communications dynamically. Intrusion detection systems (C) detect suspicious traffic but typically do not block it (unless paired with prevention). Anti-malware (D) protects against malicious software but not directly network communication filtering.

Host-based firewalls are a fundamental component of endpoint security highlighted in the Security Operations domain of SY0-701【6:Chapter 11†CompTIA Security+ Study Guide】.
