Exam CCOA Topic 2 Question 84 Discussion

To add an extra layer of remote access control to a critical online database, using aproxy server combined with a VPNis the most effective method.
* Proxy Server:Acts as an intermediary, filtering and logging traffic.
* VPN:Ensures secure, encrypted connections from remote users.
* Layered Security:Integrating both mechanisms protects the database by restricting direct public access and encrypting data in transit.
* Benefit:Even if credentials are compromised, attackers would still need VPN access.
Incorrect Options:
* A. Incremental backups:This relates to data recovery, not access control.
* C. Implementation of group rights:This is part of internal access control but does not add a remote protection layer.
* D. Encryption of data at rest:Protects stored data but does not enhance remote access security.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Remote Access Security," Subsection "Securing RemoteAccess with VPNs and Proxies" - VPNs combined with proxies are recommended for robust remote access control.
