CompTIA SY0-701 Actual Questions

Detailed Explanation:Swipe cards and biometric scanners are commonly used to control on-premises access due to their reliability and ability to restrict unauthorized entry. Swipe cards provide physical access control, while biometric scanners ensure identity verification.

A vulnerability scan is the most likely method to identify legacy systems. These scans assess an organization ' s network and systems for known vulnerabilities, including outdated or unsupportedsoftware (i.e., legacy systems) that may pose a security risk. The scan results can highlight systems that are no longer receiving updates, helping IT teams address these risks.

Bug bounty programs are used to incentivize external researchers to find security flaws, but they are less effective at identifying legacy systems.

Package monitoring tracks installed software packages for updates or issues but is not as comprehensive for identifying legacy systems.

Dynamic analysis is typically used for testing applications during runtime to find vulnerabilities, but not for identifying legacy systems​​.

Accounting logs user activities such as log-ins and usage duration, which is part of the AAA framework (Authentication, Authorization, and Accounting).

=================

An obfuscation toolkit is used by developers to make source code difficult to understand and reverse engineer. This technique involves altering the code ' s structure and naming conventions without changing its functionality, making it much harder for attackers to decipher the code or use debugging tools to analyze it. Obfuscation is an important practice in protecting proprietary software and intellectual property from reverse engineering.
