Other approaches to information security management

Many of the approaches to planning an ISMS to be found in the literature follow a three-phase, rather than a four-task, approach. For instance, Moses (1994) stipulates seven steps in three phases:

  • initiation: the identification of information assets and their security requirements;

  • analysis: the identification of possible risks to the security requirements of information assets, of the vulnerabilities to those risks, and of

6.10 To extend or include?

Whatever kind of system you intend to develop, you will need to consider its security. Usually, we allow only trustworthy people to use a new system. Therefore, in a software solution we can envisage a log-on use case, which describes how a user gains access through some authentication procedure. How should such a requirement be included in the example of the hotel chain?

By analogy with natural languages, the UML allows a number of ‘grammatically correct’ options each of which will

24.973 Advanced Semantics (MIT)
This course is the second of the three parts of our graduate introduction to semantics. The others are 24.970 Introduction to Semantics and 24.954 Pragmatics in Linguistic Theory. Like the other courses, this one is not meant as an overview of the field and its current developments. Our aim is to help you to develop the ability for semantic analysis, and we think that exploring a few topics in detail together with hands-on practical work is more effective than offering a bird's-eye view of every

3 Hero and author

What, if anything, does Doctor Faustus tell us about its notorious author? Having read the play, do you feel that it supports or invalidates the dominant view of Marlowe as the bad boy of Elizabethan drama? There is certainly no doubt that the play has a defiant streak, that it calls into question the justice of a universe that places restrictions on human achievement and demands the eternal suffering of those who disobey its laws. On this level, it does seem to be the work of an autho

2.2 We are part of nature

Take a few minutes to look around at your surroundings before you read on. What do you see? Obviously this depends on where you are at the moment: at home, at work, or perhaps travelling in between, or maybe you have the misfortune to be laid up in hospital. Possibly like me you are at home. I am fortunate to have a study where I do much of my writing and you won't be surprised to hear that I'm looking at a computer screen at the moment. What else can I see? Books and bookshelves, furniture o

Iconic Penn State elm taken down over spring break 2012
This video montage mixes real-time and timelapse footage to capture Penn State arborists as they cut down the east matching elm in front of Old Main.
