Network intrusion detection system

bank of West Virginia. Protecting information uses the same principals as protecting your personal belongings. Would one leave their house unlocked when they left for a week’s vacation? You keep your personal belongings out of others reach by locking them up or hiding them in a safe place. Computer security is important to an Information system to ensure the Confidentiality, Integrity, and availability is not compromised. There are many ways to secure a computer based information system. The most important way to secure the system is to physically secure it. When securing a system it is advantageous to use layers of defense. If the outermost layer…

Both firewalls and intrusion detection systems are used to monitor network traffic and implement network security policies. Research these technologies and determine how they are similar and how they differ. Are both needed? Explain your answer in a short paper. Firewall From a definition standpoint, a firewall is a hardware or software used in a networked environment to block unauthorized access by individuals while permitting authorized communications to and from the user. The firewall is…

avoiding such attacks such as Intrusion Detection System (IDS) which is the most popular method of defense [29]. A defense federation is used in [29] for guarding against such attacks. Under this technique each cloud is loaded with separate IDS. The different intrusion detection systems work on the basis of information that is exchange between these systems. In case a specific cloud is under attack, the cooperative IDS alert all other components in the system. Trustworthiness of a cloud is…

to a new level of accounting system that is completely automated (The WritePass Journal, 2012). The Accounting Information System commonly referred to as AIS is an automated system that is computer based is mostly used for tracking most of the accounting activities in relation to information technology resources. Most of these activities revolve around…

Security Onion intrusion detection system will be selected, installed, and evaluated. A trial deployment of the intrusion detection system will be attempted in a restricted environment, then a simulated attack will be carried out, and the results analysed. Security Onion is an IDS tool that is used to monitor network security, and log management. It contains other tools like sguil, snort, Bro, Suriacata, and OSSEC amongst others. The main functions of Security Onion are capturing packets,…

the college’s data and systems at one point. Furthermore, I discovered many vulnerabilities in college’s systems, I captured them before the intruders can get their hands on them and make an effort to exploit the vulnerabilities. Moreover, I gave many suggestions on how to fix and secure on many issues that were affecting the college’s network and systems. The malware threats that I saw on the campus systems stunned me when I ran an anti-virus protection…

13. Intrusion detection and prevention Early detection and monitoring of intrusions can prevent possible attacks or minimise their impact on computer systems. This policy is designed both to protect the confidentiality of any data that may be stored on the mobile computer and to protect the organizational network from being infected by any hostile software when the mobile computer returns. This policy also considers wireless access, every host on the organizational network and the entire data…

Firewalls can be deployed on a machine, router, or LAN switch for service, direction, user, and behavior control. The firewall categories are: packet filtering firewall, which is beneficent in controlling the Internet Protocol (IP) address spoofing, source routing, and tiny fragments attacks; stateful inspection firewalls; application level gateways; and circuit level gateways. Similarly, the IPS systems are either host-based or network-based. Host-based IPS is used to protect against the…

A network allows computers to exchange data. In computer networks, devices exchange data using a data link. The connections are made using cable or wireless connection. Maintaining network security throughout an organization can be quite challenging and is indeed a tough job, but it is attainable and can be achieved. Network security is all about keeping the network safe for all devices and computers on the system. There are certain measures and skills needed to keep a network safe. There are…

that support both IPv4 and IPv6 such as, tunneling and dual-stack configurations, have some security consequences. Also, many of the network devices such as IDS (intrusion detection system), IPS (intrusion prevention system), and firewalls require a special security mechanism to support and accept this…
