Lab 7 Security Controls 100 Points Using Security Controls R

Lab 7 Security Controls 100 Ptsusing The Security Controls Reviewe

Using the security controls reviewed last week (STIG documents, the OWASP-10, and CIS), select five (5) security controls from at least two of those security control frameworks. Perform an assessment of their compliance and make as much progress as is practical to implement the control, recognizing that many of the follow-on steps are beyond the scope of our environments; in these cases, make sure to describe what you did to evaluate, what you did to mitigate, and what would still require action to fully comply. Use the Security Controls Synopsis template for each control. Each control should get 1-2 pages of attention, resulting in a single PDF that contains 5-10 pages.

Address meaningful controls applicable to your target environment, which for most of you will be your LAMP stack, but if you’re feeling adventurous, you can choose to use a real-world system or a pet project as the target, so long as it is applicable to the type of security controls we’re focusing on within Data & Application Security. Do not include work done as part of your job, do not include repeats (same topic from two control frameworks), and don’t use more than one control that is mostly “Not Applicable”. Treat this as a work deliverable: use critical thinking and check your writing/spelling for completeness.

Paper For Above instruction

The pivotal role of security controls within the landscape of cybersecurity cannot be overstated. They serve as foundational pillars that delineate best practices, mitigate vulnerabilities, and enhance the resilience of systems against evolving threats. In this assessment, five security controls spanning at least two different frameworks—namely DISA Security Technical Implementation Guides (STIGs), the Center for Internet Security (CIS) benchmarks, and the Open Web Application Security Project (OWASP) Top Ten—are critically examined within the context of a LAMP (Linux, Apache, MySQL, PHP) stack environment. This environment represents a typical web application deployment that is susceptible to various security threats, and thus, serves as an ideal testing bed for assessing and implementing security controls.

Control 1: Enforcing Security Configuration Standards According to DISA STIGs (Linux Server)

Disparate misconfigurations in Linux servers expose systems to compromised integrity, unauthorized access, and other risks. The DISA STIG for Linux provides detailed directives for securing Linux operating systems. An initial assessment involves auditing current configurations against STIG benchmarks using automated tools such as OpenSCAP. The evaluation revealed that specific services like SSH were running with root login enabled, and unnecessary packages were installed, increasing attack surface.

Mitigation efforts included disabling root login over SSH, configuring SSH to use key-based authentication, and removing unused packages. While these steps align the environment closer to the STIG standards, ongoing compliance requires continuous monitoring and configuration management—particularly ensuring that future system updates do not inadvertently disable security settings. Implementing automated compliance checks via Ansible or Chef can sustain adherence over time.

Remaining gaps pertain to the need for comprehensive auditing of file permissions, audit logging, and regular vulnerability scans. The scope extends beyond initial configuration by embedding security into our CI/CD pipelines, ensuring updates do not regress security posture.

Control 2: Applying CIS Benchmark for Apache Web Server

The Apache web server underpins the LAMP stack, making its secure configuration critical. The CIS Benchmark for Apache recommends disabling directory listing, setting proper permissions, and configuring SSL/TLS settings. A manual and automated assessment using Lynis and manual review indicated that directory listing was enabled, and SSL was only partially configured, exposing the server to man-in-the-middle threats.

Mitigation involved disabling directory listing, enforcing strong SSL/TLS protocols, and implementing HTTP Strict Transport Security (HSTS). These configurations reduce avenues for attackers to probe or intercept traffic. To fully comply with CIS recommendations, further steps include enabling mod_security for web application firewall capabilities and deploying automated scans for vulnerabilities such as SSRF or XSS.

Ongoing challenges include maintaining exact SSL configurations and monitoring for new vulnerabilities via automated tools like Qualys or Nessus, integrated into the development lifecycle.

Control 3: Implementing OWASP Top Ten Mitigation Strategies in PHP Applications

The OWASP Top Ten highlights the most critical security risks to web applications. For PHP-based apps, common issues include injection flaws, broken authentication, and sensitive data exposure. An assessment involved code review and vulnerability scanning using OWASP ZAP, which identified reflective XSS and insecure session management practices.

Mitigation measures adopted included input validation, output encoding, and secure cookie attributes. For example, applying Content Security Policy (CSP) headers helps mitigate XSS, while using PHP's filter_var() functions enforces sanitized inputs. These steps directly address OWASP's recommendations and improve the application's resilience.

Further actions necessary involve integrating static code analysis tools, employing Web Application Firewalls (WAF), and regularly updating dependencies to patch known vulnerabilities, emphasizing the importance of a layered security approach.

Control 4: Database Security Following CIS Benchmarks

Securing MySQL involves configuring proper authentication, encryption, and access controls. Initial assessment using CIS benchmarks indicated default credentials still in use, and database access was granted broadly. Mitigations implemented included disabling remote root login, enforcing SSL connections, and creating specific user roles with least privilege principles.

Full compliance requires routine audits of user permissions, enabling binary logging for audit trails, and deploying database activity monitoring tools such as MySQL Enterprise Audit. These actions are vital to prevent privilege escalation and data exfiltration. Automating periodic audits via scripts or security tools ensures sustained adherence.

Control 5: Network and Firewall Security Integration

Network security involves defining proper rules for firewalls to restrict unwarranted traffic. Assessment using network scanning tools such as Nmap revealed open ports inconsistent with the operational requirements of the LAMP stack. Mitigation consisted of configuring iptables or ufw to block all unnecessary inbound traffic, leaving only essential ports for HTTP, HTTPS, and SSH open.

Full compliance necessitates establishing an intrusion detection system (IDS) like Snort, implementing VPNs for remote access, and logging all connection attempts. These layers of security fortify the network perimeter and facilitate early detection of malicious activity.

Conclusion

The systematic evaluation of these controls underscores that a layered security approach combining configuration management, application security, database protection, and network defense is essential. While significant progress can be made within the scope of this assessment, achieving comprehensive compliance demands ongoing monitoring, automation, and integration of security practices into the development lifecycle. These actions collectively create a resilient environment capable of resisting and responding to sophisticated cyber threats.
