    Study Notes

    Network Infrastructure Security

    • Network-level infrastructure security consumes most resources in an enterprise's infrastructure security program.
    • The network level is the largest and most vulnerable part of the enterprise in terms of security risk.
    • Vulnerabilities in network infrastructure are mainly attributed to software and firmware that operate the network infrastructure.

    Importance of Network Infrastructure Security

    • Administrators must maintain the highest level of diligence in network infrastructure security.
    • Applying patches, double-checking configurations, and developing policies are essential for network security.

    Benefits of Infrastructure Security

    • Infrastructure security protects hardware, software, users, and data from attacks.
    • It minimizes financial risk and ensures compliance with privacy legislation.
    • Implementing infrastructure security offers numerous benefits to the enterprise.

    Cybersecurity Solutions

    • Cybersecurity solutions are key tools used to protect infrastructure.
    • They can ensure authorized access, prevent malware, assess network security, and encrypt data.

    Infrastructure Security Threats

    • Ransomware attacks are becoming more common and widespread.
    • Botnets are used to launch DDoS attacks, mine cryptocurrencies, and target IoT infrastructure.
    • Physical theft can compromise infrastructure security.

    Techniques to Secure Infrastructure

    • Ensure internet-based assets use secure protocols like SSH and SSL.
    • Stress-test systems regularly using security scans and penetration tests.
    • Regularly backup all systems to defend against ransomware attacks.

    Infrastructure Security Solutions
