Ensuring the security of computer systems and, crucially, the information
they need is vital. Organisations and customers require confidence
in these matters and security is critical to the successful deployment
and use of IT. In this unit learners will consider physical security
of computer systems from simple locks to complex biometric checks,
as well as software-based security using, for example, passwords,
access rights and encryption.
Potential threats to security arise in different ways. For example,
security problems are sometimes related directly to malicious intent
from internal or external sources, but in other circumstances such
as software piracy, problems can occur by accident or unknowingly.
The advent of e-commerce brought with it a whole new set of potential
threats and issues for organisations to deal with.
Successful completion of this unit will ensure that all learners
and new entrants to the IT industry understand the underlying principles
of systems security as well as developing the knowledge to apply
these principles to ensure the security of systems they will be
using. Specific technologies, risks and preventative measures are
considered as well as organisational issues, constraints and policies
that impact security, along with the legislation specifically relating
to computer use.
Security measures are usually 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.
On completion of this unit a learner should:
1 Understand the impact of potential threats to IT systems
2 Know how organisations can keep systems and data secure
3 Understand the organisational issues affecting the security of
