Week 8

 The internet protocol version 6 (IPV6) is a suite of standard protocols for the network layer of the Internet, IPV6 is designed to solve many of the problems of the current Internet protocol suite (IPV4) about address depletion, security, and auto-configuration. IPV6 expands the capability of the internet to enable new kinds of applications including peer-to-peer and mobile applications.

IPV6 addresses are 128 bits long, the reason for this is to subdivide the available addresses into a hierarchy of routing domains that reflect the internet's topology. The total number of IPV6 addresses in the world is 340 undecillions, an example of an IPV6 address is 2001:0db8:85a3:0000:0000:8a2e: 0370:7334. It is represented as eight groups of four hexadecimal digits, each group representing 16 bits. The groups are separated by colons, the first 64 bits of the address are for routing and the last 64 bits are for representing the interface or node.

System Hardening Week 12.

  Network automation offers several compelling benefits, and its impact on IT professionals is significant. Below are some advantages.   Benefits of Network Automation: It eliminates manual tasks by automating network processes. This boosts IT productivity, allowing professionals to focus on strategic initiatives that drive business growth. Network automation enables faster provisioning of critical data services, optimizes network performance, and speeds up the rollout of new services and applications. Previously infrequent network changes have become more frequent due to automation, reducing manual adjustments' time-consuming and resource-intensive nature. It helps build a reliable network for an infrastructure-as-code approach that consistently maintains network state and configuration, enhancing reliability from data centers to edge location...

System Hardening week 10

  A Virtual Private Network (VPN) enables secure remote access to corporate resources. Critical aspects of VPN policies include: Connection Procedures: Employees with VPN privileges must ensure unauthorized users are not allowed access. VPNs should enforce robust authentication methods and secure data transmission. Security Measures: VPN users must comply with information security policies, use up-to-date anti-virus software, and configure their equipment correctly. Impact Assessment: Microsoft recently faced DDoS attacks that disrupted services like Outlook and OneDrive. While DDoS attacks mainly cause inconvenience, they can disturb global commerce if they affect critical services.
