 the methods used to eradicate means of attack, this can be: Disabling unused network ports strict password management using multi-FA updating computer systems to patch out bugs removing non essential programs setting time limits staff training  rotating generated passwords Network hardening best practices Ensure your firewall is properly configured and that all rules are regularly audited and updated as needed Secure remote access points and remote users Block any unnecessary network ports Disable and remove unused or extraneous protocols and services Encrypt network traffic Server hardening best practices All servers should be established in a secure data center Harden servers before connecting them to the internet or external networks Avoid installing unnecessary software on a server Compartmentalize servers with security in mind Use the principle of least privilege when setting up superuser and administrative roles Application hardening best practices Remove unnecessary co...

 Cloud computing refers to the outsourcing of IT services and infrastructure, allowing them to be remotely accessed from anywhere, boosting efficiency. the four different categories are: Public - can be used by anyone who pays, very large services such as AWS or google cloud are included private - can be used by people within an organisation, usually password protected, used for work at home within a job community - designed for and used by a group of organisations within a particular industry to allow all businesses to provide better services Hybrid - using multiple categories each one for different things eg public, but the private for sensitive information handling Delivery models of cloud computing There are 6 delivery models IaaS (Infrastructure as a Service): Provides virtualized computing resources like servers, storage, and networking over the cloud. Example: AWS EC2, Microsoft Azure. PaaS (Platform as a Service): Offers a development environment to build, test, and deploy ...

 Methods used to implement digital resilience risk analysis of digital system's resilience by testing it against penetration testers/white hat hackers planning for disruption scenarios such of data leaks or loss due to cyber criminals, or natural disasters planning disaster recovery and conducting recovery exercises in case of said data leaks documenting lessons learnt, how you can improve on your response for if it happens again, and how you can stop it from happening again installing new software updates and new hardware in replace of older versions as newer systems patch bugs that can lead to security breaches adding redundancy to systems, so if data is lost, it can be recovered as it will have a copy device hardening (removing unneeded apps, ports and permissions) to stop people being able to plug in malicious hardware such as thumb drives with malware on them maintaining effective backup systems, in the case of large scale data loss, it can all be recovered if stored elsewhere...

Components and applications of physical computing systems Chassis (case) the housing that organises and protects the components, it is important to consider the form factor when getting a chassis, this includes, size, shape and physical specs, it is also useful for aesthetics, noise reduction of the fans, cooling, and protection from dirt etc Optical drive a computer disk drive that reads on writes data from optical disks such as CDs or DVDs the optical drive rotates at a constant speed and the data is read using a laser which is spread out across the inserted disk using the lens embedded in the optical drives head Motherboard motherboards have different form factors, and are the main printed circuit board within a computer, they contain busses , as well as hold all the components eg CPU, RAM, heatsink, RAM, BIOS and all ports Central processing unit the CPU is the electronic circuitry that carries out instructions of a computer by performing arithmetic, logic, control, input/output op...
