Ensuring the security of computer systems and, crucially, the information that is held on computer systems is vital. Organisations and customers require confidence in these matters and it is critical to the successful deployment and use of ICT. Lots of useful links available on the Links page. This ad for a commercial systems management system is also worth a look.

Security in this unit covers physical security of computer systems as well as software-based security using, for example, passwords, access rights and encryption.

Occasionally, security problems relate directly to malicious intent but in other circumstances, for example software piracy, they can occur by accident or unknowingly.

The successful completion of this unit will ensure that all learners and new entrants to the IT industry understand the underlying principles as well as being able to apply these principles to ensure the security of the systems they will using.

Specific technologies, risks and preventative measures are considered as well as organisational issues, constraints and policies that impact security. Usually security measures are in place to serve and protect our privacy and our rights. Security procedures can threaten these rights, for instance the right to have private email. The trade off between security and freedom raises important ethical issues and this unit also allows learners to consider ethical decisions and how they can be managed effectively in a modern organisation.

This unit is part of the 2007 Edexcel National Diploma programme, for which full details can be found in the course manual at this link.
