With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders. External intruders are individuals who are not authorized to access the system and attack it using various techniques. Internal intruders are individuals who are authorized to access the system but perform unauthorized activities on the system. An IDS watches activities performed on the network and searches for malicious …show more content…
Misuse detection is used to identify previously known attacks for which they require before hand knowledge of attack signature. the disadvantage of this method is that prior knowledge of the attack is required and hence new attacks cannot be identified until new attacks signature have been developed for them. In anomaly detection system monitors activity to detect any significant deviation from normal user behavior compared to known user standard behavior, this type of intrusion detection can effectively protect against both well known and new attacks since no prior knowledge about intrusion is required.
One of the most significant aspects of Intrusion Detection System is the use of Artificial Intelligence techniques[39] to train the IDS about possible threats and gather information about the various traffic patterns to infer rules based on these patterns to distinguish between to differentiate between normal and intrusive

418 Words | 2 PagesTo explain this estimator take the following example: Let S(t) be the probability that a member from a given population will have a lifetime exceeding time, t. For a sample of size N from this population, let the observed times until death of the N sample members be t_1≤t_2≤t_3≤〖… t〗_N Corresponding to each ti is ni, the number "at risk" just prior to time ti, and di, the number of deaths at time ti. Note that the intervals between events are typically not uniform. For example, a small data set might begin with 7 cases. Suppose the survivals of these seven patients (sorted by length of years) are: 1, 2+, 3+, 4, 5+,10, 12+.

It is not port specific and can be configured on any port. This feature enables OpenSSL VPN traffic indistinguishable from other HTTPS traffic and not easily gets blocked. AES encryption makes it more secure than blowfish encryption.

91 Words | 1 PagesLab 7: Moon Phases was designed to measure the relative position of the Sun and Moon over the course of one phase cycle (i.e. one month, 29.5 days) The idea for Lab 7: Moon Phases was to examine how the illumination of the moon by the Sun produces the different phase cycles we see as the Moon rotates around Earth and as the Earth rotates around the Sun. The observations of the Moon were taken on four different days in the month of February to March capturing four different Moon Phases.

178 Words | 1 PagesI do have a question, why are we having these issues with kits that were provisioned for Accredited Heath Care? These are new kits and were tested I believe before they arrived to me. This is the MAIN reason why I can no longer have kits go directly to our clients without testing myself. If this kit went to the client this account would be lost before it even began. They (Accredited) are testing to see how we do and if the devices work like we say they do.

The reputation values of peers, however, are calculated by aggregating its documents ' reputation values. Technically, the super-peers build a 2-tuple of peer and documents reputation vector as esizebox{0.27 extwidth}{!}{$(P_{i}, (Rep(d_{1}), Rep(d_{2}), ..., Rep(d_{n})))$} where $P_{i}$ is peer $i$ belong to super-peer $S_{j}$ and $Rep(d_{k})$ refers to the document reputation value as calculated in Equation ef{Reputation_documents}. The peer 's reputation value is aggregated from other users ' feedbacks on its documents as in Equation ef{RepPeer}. egin{equation} Rep(P_{j})

425 Words | 2 PagesThe objective of this piece was to create something meaningful to me, that will flow together well by using audio files. I’m a huge fan of the piano, so I knew that I wanted to incorporate a piano in the piece. Surprising enough the main part of the whole piece is the pinaoloop2 on a loop. The work process for this piece primarily involved getting the audio samples that will work nicely around my main piece which is the pianoloop2. After obtaining the audio files, the major software that I use to get the sounds together was Audacity.

1058 Words | 5 PagesBreak Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies. Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not. Personally, my musical tastes are all across the board, and change
