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...

  Most recent Cybersecurity attacks: 2022     British Council data breach   The British Council, which provides English language courses to students worldwide, experienced a third-party data breach revealing more than 10,000 records. Researchers discovered an unprotected Microsoft Azure blob repository and reported the incident on the 5th of December 2021.       The blob container (a group of data held in the cloud) was indexed by a public search engine. Clario Tech reported in a Mackeeper blog that the blob contained at least 144k xls , xlsx, xml, and Json files.       The datasets held students’ personal data worldwide, including student IDs, full names, study duration, email addresses, and enrolment dates.       Any student or individual that may have been affected by the data breach should change their password straight away. They should also watch out for suspicious-looking emails and links.   The NHS Trus...

System hardening and networking week 5

  A Virtual Local Area Network (VLAN) is a logical network that groups devices based on their functionality, location, or security requirements. Here are some advantages of VLANs: Advantages: Improved network performance: VLANs can reduce congestion by segmenting the network into smaller broadcast domains. This reduces the amount of traffic that needs to be processed by each device, leading to faster network speeds. Enhanced network security: VLANs can isolate sensitive data and restrict access to it. This helps prevent unauthorized access to confidential information and reduces the risk of data breaches. Simplified network management: VLANs can simplify network management by allowing administrators to manage groups of devices as a single entity. This reduces the complexity of network management and makes it easier to troubleshoot network issues. Flexibility: VLANs can be easily reconfigured to meet changi...
