 Week 11 - Network Hardening


Network Hardening is the process of securing a network to protect it from threats and reduce vulnerabilities. Here are some key steps to harden a network:

  1. Firewall Configuration: Set up firewalls to block unauthorized traffic and control access to your network.

  2. Network Segmentation: Divide the network into smaller sections to limit access to sensitive areas and reduce the spread of threats.

  3. Encryption: Encrypt data to keep it secure during transmission, and use VPNs for secure remote access.

  4. Access Control: Use strong passwords, multi-factor authentication (MFA), and role-based access to control who can access the network.

  5. Patch Management: Regularly update software and devices to fix vulnerabilities and prevent exploits.

  6. Intrusion Detection Systems (IDS/IPS): Monitor network traffic for suspicious activity and block potential threats.

  7. Monitoring and Logging: Continuously monitor network activity and store logs to detect and investigate unusual behavior.

  8. Physical Security: Secure hardware by restricting physical access to network devices and sensitive areas.

  9. Employee Training: Educate employees about safe practices, such as identifying phishing attempts and using strong passwords.

  10. Backup and Recovery Plans: Keep regular backups of important data and test recovery processes to ensure quick restoration in case of an issue.

Week 12

 Week 12 Networking has evolved significantly over the past decade, with advancements in technology bringing both new challenges and solutions. Here’s how the landscape has shifted: 1. Increased Cybersecurity Threats Then: Cybersecurity threats were primarily focused on malware and traditional hacking attempts targeting enterprise networks. Now: The rise of ransomware, phishing attacks, and zero-day vulnerabilities has made network security more complex. Attackers now exploit IoT devices, cloud services, and remote work environments. Improvements: AI-driven threat detection, Zero Trust security models, and stronger encryption protocols have enhanced network security. 2. Rise of Cloud Networking Then: On-premises data centers dominated networking infrastructures. Cloud adoption was in its early stages, and hybrid environments were uncommon. Now: Businesses now rely heavily on cloud services, requiring scalable and flexible networking solutions to manage hybrid and multi-c...

Week 2 Blog Post

I knew that cables and connectors existed, but I had no idea there were so many different types. Twisted pair cables are commonly used because they’re easy to handle and provide reliable speeds over short distances. Then there are fiber optic cables, which I’m familiar with since I use them for my internet and the speed is impressive. This week, the chapter also covered network architecture and the devices that enable data transmission. Ethernet is a widely used method for devices to connect and share information. Devices like hubs, switches, and routers play a crucial role in directing the data traffic. Hubs send data to all devices, while switches are more efficient, routing data only to the intended recipient. Routers connect networks such as  home networks or office networks to the internet. Understanding how these devices work together is key to effective network management and troubleshooting.
