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
- Firewall: Prevents malicious traffic from accessing internal networks.
- Antivirus or antimalware systems: Scan email messages, web traffic, and hardware devices for malware.
- Penetration testing and network vulnerability analysis tools: Identify potential security problems.
