 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: Firewall Configuration : Set up firewalls to block unauthorized traffic and control access to your network. Network Segmentation : Divide the network into smaller sections to limit access to sensitive areas and reduce the spread of threats. Encryption : Encrypt data to keep it secure during transmission, and use VPNs for secure remote access. Access Control : Use strong passwords, multi-factor authentication (MFA), and role-based access to control who can access the network. Patch Management : Regularly update software and devices to fix vulnerabilities and prevent exploits. Intrusion Detection Systems (IDS/IPS) : Monitor network traffic for suspicious activity and block potential threats. Monitoring and Logging : Continuously monitor network activity and store logs to detect and investigate unusual ...

 Week 10  Network Segmentation Security Network segmentation is a critical cybersecurity practice that involves dividing a network into smaller, isolated sections to enhance security, improve performance, and restrict access to sensitive data. This strategy helps prevent unauthorized access, contain cyber threats, and improve overall network management. Benefits of Network Segmentation Enhanced Security Restricts access to sensitive systems, ensuring that only authorized users and devices can interact with critical data. Limits the lateral movement of attackers within the network, reducing the impact of malware, ransomware, and insider threats. Reduced Attack Surface Minimizes the exposure of critical assets by separating them from less secure areas of the network. Prevents threats from spreading across the entire infrastructure. Improved Network Performance Reduces congestion by limiting unnecessary traffic between network segments. Helps prioritize bandwidth for critical app...

  Week 9 Post WiMax is a wireless broadband technology with both benefits and challenges: Benefits: Better Access: It brings high-speed internet to rural and underserved areas. Economic Growth: Helps businesses expand and creates jobs. Education & Healthcare: Enables online learning and telemedicine. Affordable & Mobile: Cheaper to install and allows internet on the go. Innovation: Encourages new tech and increases competition. Challenges: Limited Coverage: Struggles with range and interference in some areas. Security Risks: Vulnerable to hacking and privacy issues. High Setup Costs: Expensive to install, especially in sparsely populated areas. Obsolete Tech: Newer technologies like 5G could replace it. Health Concerns & Incompatibility: Worries about health risks and device compatibility. Conclusion: WiMax can improve internet access but faces challenges in range, security, and future relevance

 Week 8  IPv6 is the latest version of the Internet Protocol, designed to replace IPv4. It uses a 128-bit address system, allowing for a much larger number of unique IP addresses than IPv4, which only supports 4.3 billion addresses. Key benefits of IPv6 include: More IP Addresses : With 340 undecillion possible addresses, IPv6 can support the growing number of devices on the internet. Faster and More Efficient : The IPv6 header is simpler, helping data move more efficiently. Built-in Security : IPv6 includes security features, like IPsec, to protect data transmissions. Better for Mobile Devices : It supports automatic address configuration and improved mobile device performance. No Need for NAT : Each device can have its own public IP address, removing the need for Network Address Translation used in IPv4. IPv6 is essential for the future growth of the internet, as it allows more devices to connect and operate more efficiently.
