Common Approaches To Analysing Security Risk
Some security professionals define security according to one of the following formulas.
Risk = Threat × Harm
Risk = Consequence × Threat × Vulnerability
Risk = Consequence × Likelihood
Risk = Consequence × Likelihood × Vulnerability
However, Jeff Lowder has argued that the Risk = Consequence x Threat x Vulnerability is "mathematical nonsense."
Factor Analysis of Information Risk deeply analyze different risk factors and measure security risk.
There are a number of methodologies to analyse and manage security risk: see Category:Risk analysis methodologies

Famous quotes containing the words common, approaches, security and/or risk:
“If music in general is an imitation of history, opera in particular is an imitation of human willfulness; it is rooted in the fact that we not only have feelings but insist upon having them at whatever cost to ourselves.... The quality common to all the great operatic roles, e.g., Don Giovanni, Norma, Lucia, Tristan, Isolde, Brünnhilde, is that each of them is a passionate and willful state of being. In real life they would all be bores, even Don Giovanni.”
—W.H. (Wystan Hugh)
“As the truest society approaches always nearer to solitude, so the most excellent speech finally falls into Silence. Silence is audible to all men, at all times, and in all places. She is when we hear inwardly, sound when we hear outwardly. Creation has not displaced her, but is her visible framework and foil. All sounds are her servants, and purveyors, proclaiming not only that their mistress is, but is a rare mistress, and earnestly to be sought after.”
—Henry David Thoreau (1817–1862)
“In the long course of history, having people who understand your thought is much greater security than another submarine.”
—J. William Fulbright (b. 1905)
“When a man leaves his mistress, he runs the risk of being betrayed two or three times daily.”
—Stendhal [Marie Henri Beyle] (1783–1842)
