Business Case for Security
By: Benjamin D. Thomas
Establishing a business case is perhaps the first phase in any
project initiation. Organizations that are successful maintain full
justification for all business expenditure. An information security
project is no different. An effective information security program
requires visible support from executive management. To gain support,
a persuasive business case is often necessary. An information
security program will have numerous tangible and intangible benefits
to any organization. It is the role of a business case to document
these.
To build a persuasive case for information security, it is important
for practitioners to "to become more managerial in outlook, speech, and
perspectives." (Information Security Management Handbook 4th Edition,
Volume 2.) Stressing the technical benefits of information security
is no longer sufficient because of the size and expenditure of
information security programs. When making a case for information
security, an emphasis should be placed on how proactive security
mechanisms ensure that senior management will not be held liable
for negligence. As IT has become more prominent in organizations,
so have compliance and regulatory requirements. Today, senior
management personnel are expected to demonstrate due care and due
diligence in relation to information security. With this, information
security must become an essential aspect of management.
Addressing the overall benefits of information security is important
as well. A business case should stress how information security can
become a business enabler. It can be a company differentiator by
offering increased levels of customer satisfaction and contributing
overall to total quality management. Information security also
provides a means to ensure against unauthorized behavior. Often
trusting that internal employees will "do the right thing" is not
enough. Information security related business cases should be
written in a way that emphasizes all benefits of information
security.

Measuring Security IT Success
In a time where budgets are constrained and Internet threats are
on the rise, it is important for organizations to invest in network
security applications that will not only provide them with powerful
functionality but also a rapid return on investment.

Getting to Know Linux Security: File Permissions
Welcome to the first tutorial in the 'Getting to Know Linux Security'
series. The topic explored is Linux file permissions. It offers an
easy to follow explanation of how to read permissions, and how to set
them using chmod. This guide is intended for users new to Linux
security, therefore very simple. If the feedback is good, I'll
consider creating more complex guides for advanced users. Please
let us know what you think and how these can be improved.

The Tao of Network Security Monitoring: Beyond Intrusion Detection
To be honest, this was one of the best books that I've read on network
security. Others books often dive so deeply into technical discussions,
they fail to provide any relevance to network engineers/administrators
working in a corporate environment. Budgets, deadlines, and flexibility
are issues that we must all address. The Tao of Network Security
Monitoring is presented in such a way that all of these are still
relevant. One of the greatest virtues of this book is that is offers
real-life technical examples, while backing them up with relevant case
studies.
