Intrusion prevention is an approach, similar to intrusion detection. Intrusion prevention helps in identifying attacks/threats over the network and responds to the threats without any delay.
Intrusion prevention system (IPS) works similar to Intrusion detection system (IDS), where both monitor traffic over the network. However, IPS is more active in nature as it takes immediate action on the attack that has occurred. The action taken by IPS is based on the rules that have been set by the network administrator.
Intrusion prevention system performance metrics are measured in terms of:
• Dynamic alerting capability
• Lower false positives
• Threat blocking capability
• High availability, redundancy and speed of working
• Ability to correctly

• Cost Effective: IPS provides a cost effective security monitoring solutions in order to prevent various intrusions on the network.
Intrusion Prevention System (IPS) is considered to be one of the pre-emptive approaches used to detect various potential threats on the network and respond to them as quickly as possible to stop their activities over the network. It is similar to intrusion detection system which monitors various types of network traffic on the network.
In order to avoid these consequences; network administrator might define some set of security rules, in which IPS might take immediate actions to rectify the same on time. For example, there might be some chances where IPS might drop some packets without even tracking on the network. The packets which are determined to be very harmful, IPS might block the network traffic from a particular IP address or port in the network. So, we need to take necessary measures by defining the set of rules which supports the IPS activities on the network.

It is a software/hardware solution that monitors the radio waves. A wireless hardware sensor can report captured information to software to be recorded in a server database.
Some of the advantages by using a Wireless intrusion prevention system are:
• Captures information by 24/7 monitoring
• Includes elaborate reporting systems
• Supports integrated spectrum analysis
• Uses hardware sensors for monitoring Wireless intrusion prevention system consists of three components:
• Sensors: These devices contain antennas and radio which scan the wireless spectrum for
IDS is a device or software application that monitors a network for an unauthorised attack.
What does IP stand for and what is it used for? Internet Protocol, and it's a set of rules governing the format of data sent over the Internet or other
IP – The Internet Protocol (IP) - is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
These warnings can help users alter their installation’s defensive posture to increase resistance to future attacks. An intrusion detection system is comparable to a burglar alarm system. The car locks to protect the vehicle from theft. In the event someone compromises the lock, the burglar alarm detects this compromise and alarms the owner.
The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.
According to Aaron Alton the manager of IT Infrastructure the Cisco firewall solution has the ability to prevent intrusion, advanced malware protection, URL filtering and application visibility all in one product. All of these featured are done through the Firepower Management Center. The Firepower Management Center provides “extensive intelligence about the users, application, devices, threats, and vulnerabilities that exist in your network”. After this is done it then provides recommended security policies that can be put into place and tells you what security measures should be looked into further. This system costs $20.03 per protected Mbps.
Denial of Service attacks (DoS) or Distributed Denial of Service Attacks (DDoS), have been around for many years, but only in the past few years have the frequency and magnitude of these attacks increased. They are a significant problem because they can shut an organization off from the Internet for extended periods of time and little can be done to stop them. DoS attacks occur when computer resources become unavailable to legitimate users after being exhausted by false requests for information (Houle and Weaver 1).

Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help to stop unauthorized users or intruders from accessing any part of a computer system. Detection helps one to determine whether or not someone attempted to break into a computer system, if they were successful, and what they may have done.
Cybersecurity is the technology that protects computers and networks from unauthorized personnel. Ever since computers have expanded to homes and the workplace; the need for cyber security has grown exponentially. Millions of people around the world have access to the internet at a given time, and this allows for predators to attack, scam, hack, and intrude on personal and government information. Cybersecurity is designed to counteract these attempts to ultimately allow for safe networks and computers.
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Implement a system Intrusion Detection/Prevention System (IDS/IPS): - Make the investment in an IDS/IPS to distinguish and prevent potential system dangers. sensors ought to be circulated all through the system, with a specific focus on general society untrusted section. Take alerts very seriously.
