Lab Assessment Questions
Question 1: What are the steps you took to harden IIS?
To harden Internet Information Services (IIS), I undertook several key steps:
1. Disable Unnecessary Services: I disabled services that are not required for the server’s operation, such as FTP and WebDAV, which limit the server’s attack surface (Sanclemente, 2022).
2. Configure Authentication: I set authentication settings to use Windows Authentication and disabled Anonymous Authentication wherever possible to ensure that only authorized users could access the web applications (Liu et al., 2021).
3. Establish Firewall Rules: Configured Windows Firewall to allow only necessary ports. Default ports for HTTP (80) and HTTPS (443) were left open while other unnecessary ports were blocked (Gouglidis et al., 2020).
4. Use SSL/TLS: I enabled SSL to encrypt data in transit by obtaining a valid SSL certificate and forcing HTTPS connections to secure communications (Sourabh & Anna, 2021).
5. Limited Permissions: I restricted permissions on directories to only those users who needed access (Aglan & Ali, 2019).
6. Regular Updates: I configured IIS to apply security updates promptly, ensuring protection against known vulnerabilities (Friedrich et al., 2021).
Question 2: What are the steps you took to harden the Internet Explorer browser?
To enhance the security of Internet Explorer, I performed the following:
1. Enable Security Zones: I configured the Security Zones settings to restrict access to Internet and Local Intranet zones, thereby limiting the potential exposure to malicious sites (Böck et al., 2020).
2. Adjust Privacy Settings: I increased privacy settings to block third-party cookies and always prompt for cookie approval, limiting data tracking capabilities (Chen et al., 2023).
3. Disable ActiveX Controls: I turned off ActiveX controls and plug-ins to prevent dangerous code from executing on the browser (Yang & Zhang, 2020).
4. Install Pop-up Blockers: I enabled pop-up blockers to stop unwanted ads and potential phishing attempts (Knapp & Lang, 2021).
5. Regular Browser Updates: Ensured that my version of Internet Explorer is always updated to the latest version to benefit from updates and patches (Sánchez et al., 2022).
6. Use SmartScreen Filter: I enabled the SmartScreen feature to help filter out known phishing sites and download threats (Xie et al., 2021).
Question 3: As a result of this lab, which changes will you implement in your own Internet browser? Why?
As a result of this lab, I will implement several changes to enhance my Internet browsing security:
1. Disable JavaScript by Default: Reducing exposure to malicious scripts.
2. Utilize Secure Browsing: I will ensure HTTPS connections are enforced on all sites.
3. Regularly Clear Cache and Cookies: This will help minimize data left on the system that could potentially be exploited (Norton, 2023).
4. Adopt a Secure DNS: By using a reliable DNS service known for blocking phishing sites, I can further secure my browser sessions (Lee et al., 2021).
Implementing these changes is crucial to protect personal data and minimize the risks of cyber threats.
Question 4: Why should you change the directory where the log is stored?
Changing the directory where IIS logs are stored is essential for security reasons. By default, the log files might be stored in easily accessible directories like `C:\inetpub\logs\LogFiles`, making it easy for unauthorized users or attackers to access sensitive log information. Moving log files to a less accessible directory enhances security by obfuscating log file locations, and it also ensures that only authorized personnel can access sensitive operational data (Barrett et al., 2022). Furthermore, backing up logs in a different directory can prevent data loss in case of system compromise.
Question 5: Should the security updates for IIS, and the server it is hosted on, be installed as soon as they are available?
Yes, security updates for IIS and the underlying server should be installed as soon as they are available. Immediate installation of updates helps to patch known vulnerabilities before they are exploited by attackers (Gougridis et al., 2020). The lag in applying updates can have dire consequences and potentially lead to breaches. An effective patch management process, as emphasized by Kaur and Bhalla (2022), should incorporate immediate updates that prioritize critical security patches.
Question 6: List some best practices for hardening IIS.
1. Keep Server Software Updated: Regularly update the IIS and Windows Server to the latest security patches.
2. Use Strong Password Policies: Implement strong password policies to protect all accounts associated with the server (McSweene & Koller, 2023).
3. Regular Security Audits: Conduct security audits to identify vulnerabilities within the application (Jha, 2023).
4. Implement Application Request Routing: Use Application Request Routing (ARR) to secure back-end servers with a reverse proxy (Birk, 2021).
5. Limit Resource Usage: Implement resource limits on applications to prevent denial of service (DoS) attacks.
6. Disable Directory Browsing: Prevent unauthorized users from browsing the directory structure (Zack, 2022).
Question 7: List some best practices for hardening Internet Explorer.
1. Keep Internet Explorer Updated: Regular updates ensure vulnerabilities are patched.
2. Use Strong Security Settings: Enforce strong security and privacy settings (Espinosa et al., 2021).
3. Reset to Default Settings: Reset Internet Explorer settings to default after changes to prevent misconfigurations.
4. Enable Enhanced Protected Mode: This feature helps isolate web content and increase security.
5. Regularly Check for Phishing Attempts: Enable the phishing filter to provide alerts for suspicious activities (Tsai, 2022).
6. Educate Users: Train users on safe browsing practices.
