For SSDs,incinerationis considered the most secure method of physical destruction, ensuring no data remanence. SSDs store data differently compared to traditional spinning disks, making degaussing ineffective. Overwriting and formatting may not reliably erase all storage cells due to wear-leveling technologies. Shredding may work if the granularity is extremely fine, but incineration guarantees complete destruction beyond recovery.

Configuring a span port on the perimeter firewall to ingest logs is the best architectural change to ensure that all client proxy traffic is captured for analysis. Here’s why:

Comprehensive Traffic Capture: A span port (or mirror port) on the perimeter firewall can capture all inbound and outbound traffic, including traffic that might bypass the proxy. This ensures that all network traffic is available for analysis.

Centralized Logging: By capturing logs at the perimeter firewall, the organization can centralize logging and analysis, making it easier to detect and investigate anomalies.

Minimal Disruption: Implementing a span port is a non-intrusive method that does not require significant changes to the network architecture, thus minimizing disruption to existing services.

To prevent unauthorized applications from running, the company needs a mechanism to explicitly define and enforce which applications are allowed to execute. "Permit listing" (often referred to as "whitelisting" in security contexts) is the most effective solution here. It involves creating a list of approved applications, and only those on the list are permitted to run, blocking all others by default. This directly addresses the root cause—users installing unapproved software—by restricting execution to only authorized programs.

Option A (Signing):Code signing ensures the authenticity and integrity of software by verifying it comes from a trusted source and hasn’t been tampered with. While useful, it doesn’t inherently prevent unauthorized applications from running unless combined with a policy like whitelisting.

Option B (Access control):Access control governs who can access systems or resources but doesn’t specifically restrict which applications can execute. It’s too broad for this scenario.

Option C (HIPS):A Host-based Intrusion Prevention System (HIPS) can detect and block malicious behavior, but it’s reactive and relies on signatures or heuristics, not a proactive allow-only approach.

Option D (Permit listing):This is the best fit, as it proactively enforces a policy where only explicitly authorized applications can run, preventing malware introduced by unauthorized software.
