Solid core and stranded core cables are types of UTP cables, with solid core UTP each wire uses a single solid wire while with stranded core each wire is a bundle of tinny wire strands. Solid core is a better conductor but will break if handled too often or too roughly because it is stiff.

A stranded core is not quite a good conductor, but it will not break if handled roughly or too often. They are made using a collection of thin wires that are bound together to function as a single line. It is more expensive to make, and they are ideal for cramped spaces and areas like vibrating machinery.

The stranded cable also has higher attenuation which makes it better for short-distance runs and it is vulnerable to electrical interference because it has multiple wires instead of a single line. I think solid is more common than stranded because it is less expensive.

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...

  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...
