Attributes
- Traffic Analysis
- Non-evasive eavesdropping and monitoring of transmissions
- Because data unaffected, tricky to detect
- Emphasis on prevention (encryption) not detection
- Sometimes referred to as “tapping”
Types of Passive Attacks are 1) Traffic Analysis 2)Release of message contents. Traffic Analysis: In this attack the eavesdropper analyzes the traffic, determine the location, identify communicating hosts, observes the frequency and length of message being exchanged. Using all these information they predict the nature of communication . All incoming and out going traffic of network is analysed but not altered.
Release of message content: A telephonic conversation, an E-mail message or a transferred file may contain confidential data. A passive attack may monitor the contents of these transmission.
Passive attacks are very difficult to detect because they do not involve any alteration of the data. When the messages are exchanged neither the sender nor the receiver is aware that a third party has read the messages. This can be prevented by encryption of data.

Famous quotes containing the word attributes:
“True and false are attributes of speech not of things. And where speech is not, there is neither truth nor falsehood. Error there may be, as when we expect that which shall not be; or suspect what has not been: but in neither case can a man be charged with untruth.”
—Thomas Hobbes (1588–1679)
“Even though fathers, grandparents, siblings, memories of ancestors are important agents of socialization, our society focuses on the attributes and characteristics of mothers and teachers and gives them the ultimate responsibility for the child’s life chances.”
—Sara Lawrence Lightfoot (20th century)
“Why does not the kitten betray some of the attributes common to the adult puss? A puppy is but a dog, plus high spirits, and minus common sense. We never hear our friends say they love puppies, but cannot bear dogs. A kitten is a thing apart; and many people who lack the discriminating enthusiasm for cats, who regard these beautiful beasts with aversion and mistrust, are won over easily, and cajoled out of their prejudices, by the deceitful wiles of kittenhood.”
—Agnes Repplier (1858–1950)
