knowing the victims. It is not easy to stop such attacks but not impossible to stop if following basic prevention steps follows by organizations administration. • Maintain an Accurate Inventory of Control System Devices and Eliminate Any Exposure of this Equipment to External Networks • Implement Network Segmentation and Apply Firewalls • Use Secure

scientists should launch and control war? The use of computer to disrupt the activities of an enemy country, while deliberately attacking their communication systems is becoming the greatest threat the world had ever faced. Richard Clarke in his book cyber War (May 2010), defines it as “action by nation-state to penetrate another nation’s computers or networks for the purpose of causing damage or disruption.” The recent century and its technology spike had allow all nations to become a single city through

COLLECTED DATA The Danger of Cyber Attacks A cyber attack is an online malicious attack that disrupts, steals, and/or damages a system. There are numerous types of cyber attacks, and different ways to carry out one. As the world becomes more dependent on technology, the damage potential for cyber attacks increases. Government agencies around the world are even competing in cyber attacks with one another, for offensive and defensive reasons. Two popular attack methods are malware and denial-of-service

monitor threats and control activity across the network. Assignment Requirements Refer to the handout Testing and Monitoring Security Controls. It contains information on security events or breaches and baseline anomalies. After studying the handout, answer the following questions:  Identify at least two types of security events and baseline anomalies that might indicate suspicious activity.  Given a list of policy violations and security

talk about networks. Hackers and intruders are getting smarter. There are various methods to secure the network infrastructure and communication over the Internet, for example firewalls, encryption, and virtual private networks. Intrusion detection is a relatively new approach to such techniques. By using intrusion detection, we can collect and use information from known types of attacks and find out if someone is trying to attack the network/host. Keywords: intrusion detection system I. Introduction

Internet is everywhere, it is a like global network which provide and has great potential in changing the business works today. With advent of new changes in internet there has been a great change in the way organization’s business models work these days. As internet provides a platform globally to be interconnect all the time, E-business has become a trend setter to big and small companies. Hence, internet connectivity is a vital aspect of business and especially for today’s e-business. There is

wonder when companies will learn a lesson, a right lesson even. What I found fascinating about the recent Anthem breach, was that it was an employee of Anthem that discovered that something was wrong. Not a firewall, not an intrusion prevention system, not an intrusion detection system, not a web application firewall, or any other of the dozens of technologies I could mention. According to news reports [1], a database administrator noticed queries made with his/her account, that they never made. The employee

counteract these attacks such as firewalls, anti-virus software and IDS (Intrusion Detection System) [23]. Many of these require manual analysis however and approaches such as relying on host dependencies, profiling host behaviors or using deep packet inspection have been developed. These approaches have scalability issues though making them less than optimum in high speed networks [23]. The generation of Big Data over computer networks is quickly making all of these solutions somewhat obsolete though

protect the network infrastructure as well as communication over the internet, for example firewalls, encryption, and virtual private networks. Intrusion detection is a comparatively new approach to such techniques. By using intrusion detection, we can collect and use information from acknowledged attacks and figure out if somebody is trying to attack the network/host. In this paper, we have classified different types of IDS. Also we have proposed a hybrid model for intrusion detection and prevention

Intrusion Detection Intrusion detection is similar in concept to a burglar alarm on a car. There is the lock system to prevent access to a car, similar to a firewall, and there is the alarm system, the intrusion detection system. Intrusion Detection Systems (IDS) are there to compliment the network or computers firewall, if or when there is a breach, it is the IDS that is able to identify it and then alert the administrator. Firewalls are an effective way for filtering information coming in to
