Question

In your cybersecurity class, you are learning about common security risks associated with web servers. One topic that comes up is the risk posed by using default server settings. Why is using default settings on a web server considered a security risk, and what would be the best initial step to mitigate this risk?

Options

  • ADefault settings allow unlimited login attempts; setup account lockout
  • BDefault settings reveal server software type; change these settings
  • CDefault settings cause server malfunctions; simplify the settings
  • DDefault settings enable auto-updates; disable and manually patch

Why each option

Using default web server settings poses a security risk because they often expose the server software type and version, which attackers can exploit; the best initial mitigation is to change these settings to obscure such identifying information.

ADefault settings allow unlimited login attempts; setup account lockout

While unlimited login attempts are a risk, most web servers do not expose direct login interfaces by default in a way that relates to general server settings, and account lockout is usually an application or operating system feature, not a primary web server default setting security risk.

BDefault settings reveal server software type; change these settingsCorrect

Default web server settings often include banners or HTTP headers that reveal the specific server software (e.g., Apache, Nginx, IIS) and its version, which allows attackers to identify known vulnerabilities for targeted exploits; changing these default settings by removing or modifying these identifying headers prevents such easy reconnaissance.

CDefault settings cause server malfunctions; simplify the settings

Default settings are designed for functionality and stability, not to cause server malfunctions; simplifying settings does not address a security risk from defaults and is not a direct mitigation strategy for web server security.

DDefault settings enable auto-updates; disable and manually patch

Enabling auto-updates by default is generally considered a security best practice for ensuring timely patches, not a security risk, and disabling them for manual patching introduces the risk of delayed vulnerability remediation.
