Intrusion Detection System And Prevention System Essay

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

The world of cyber security continues to introduce new threats each year against network infrastructures and computer devices. In the recent years, the impact from cyber-attacks has wreaked havoc on many company brands and organizational reputations. As this issue grows so does the technology to prevent and protect against these malicious attacks. It is absolutely crucial for organizations and businesses to shift focus from defense for different types of attacks to improving safeguards to mitigate the loss of sensitive data when an attack occurs. In addition to the traditional security technology used to detect an attack, companies will have to include

When the GCU gathers evidence for later use for the court, sources of evidence can be monitored to detect threatened incidents in a timely manner. The GCU employee’s needs to be aware of suspicious transaction related to any activity in the customer account. Securing intrusion detection systems (IDS) components are important because IDS are often targeted by attackers that want to prevent the IDS from detecting attacks or want to gain access to sensitive information on the IDS, such as host configurations and known vulnerabilities. In monitoring and auditing, the types of activities recognized as suspicious will be different from different business needs. For example, a forensic accountant may look for specific patterns of financial data to trigger suspicion of fraud or theft. A suspicious event might be multiple emails on a sensitive subject from a person that is not involved in the subject. Recommend resources that can be used

Two weaknesses were found in regards to the company 's network security. First weakness is a hardware weakness; and another is IDS which not having a Network-based Intrusion Detection System (IDS) in use. The recommended solutions are to show an AAA server for user authentication and authorization to company resources, and deploy a combination Host and Network-based IDS for overall monitoring of the company 's enterprise.

With another breach hitting the news (Anthem), I often 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 reported it, and the trickle effect occurred spurring the notification of Anthem being breached. Kudos to the alert employee, and shame on the technology that failed Anthem. That in itself - “shame on the technology” - was not a fair statement but was somewhat meant to get your attention. Did it work?

Identification of an incident can be achieved by recognizing the symptoms of it. These can include any number of situations or circumstances, including unusual computer or network behavior, notification from an intrusion detection device, a review of system log files indicating unusual entries, loss of system connectivity and device malfunctions. It is essential that these symptoms be communicated to all users, for if they do not recognize it they cannot report it. Once a viable threat is identified, communicating and alerting to all that are currently or may be involved about the threat is essential for isolation and further infection.

Information security enabled by technology must include the means of lowering the impact of intentional and unintentional errors entering the system and to prevent unauthorized internally or externally accessing the system  actions to reduce risk data validation, pre-numbered forms, and reviews for duplications. It is crucial that the mission plan include the provision of a disaster recovery and business continuity plan. On the other hand, there is much more intrusion activity today than ever before. Obviously, there is an increased concern for attacks through companies’ network in an effort to either commit malice or affect the integrity of an organization’s most valuable resource. Therefore, it is important that companies do not get complacent in their IT infrastructure security. The fact of the matter, there is no perfect system; however, it behooves organizations to protect their information by way of reducing threats and vulnerabilities. Moreover, Whitman and Mattord (2010) said it best, “because of businesses and technology have become more fluid, the concept of computer security has been replaced by the concept of information security. Companies

2.4.7 Rapid intrusion detection and response procedures: KIU should have mechanisms in place to reduce the risk of undetected system intrusions. Computing systems are never perfectly secure. When a security failure occurs and an attacker is "in" the institution's system, only rapid detection and reaction can minimize any damage that might occur. Techniques used to identify intrusions include intrusion detection systems (IDS) for the network and individual servers (i.e., host computer), automated log correlation and analysis, and the identification and analysis of operational

These proposals and systems suggestions can minimize the vulnerabilities associated with any compromises or intrusions within the network. Deploying an intrusion detection system is an essential security strategy for monitoring a network information system for abnormal or authorized activity. An intrusion detection system (IDS) is set of tools which monitor a network topology by providing a system administrator with the overall picture of how the system is being utilized. Executing an IDS will make a difference in creating a defense in depth architecture to be more compelling in recognizing any form of malicious activities. The capacity of the IDS is to monitor and survey the network traffic without affecting network activity. IDS tools gather information and analyzes it against a pre-characterized manage set, and against a set of known assault 'marks'. The IDS can scan port numbers and to determine if any breaches or attacks are occurring (Kuipers,

In today’s world it is highly impossible for any kind of business to function without the assistance of technology. Any company that relies on digital data and computer networks have exposure to a host of varying Cyber Attacks. As technology continues to evolve, cyber security breaches become even more difficult to solve. The cybersecurity world rightly believes in the maxim – It’s not if, it’s when!

The goal of intrusion detection is to monitor network assets, detect anomalous behavior, and identify misuse within a network (Ashoor, Gore, 2011). An intrusion detection system (IDS) is a device or software application that monitors network system activities for malicious activity or policy violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013), additionally there are three types of IDS:

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

In an e-commerce world, organizations are susceptible to hackers and intruders. Thus creating the information technology protection systems which is used to reduce the possibility of intrusions from occurring. Intrusions occur by uninvited outsiders (sometimes intruders can be internal users like employees) who try to access an organization’s information system using the internet with the intent to gain competitive advantage of some sort. Organizations depend on security technology to avoid loss from security breach, as well as to improve their efficiency and effectiveness. However, firewalls are also vulnerable to errors, and implementing a security technology comes with challenges and critical decisions that can possibly cause a financial burden on the organization if done without seriousness and commitment. “Information security is about managing risk, and managing risk is about discovering and measuring threats to information assets; and taking actions to respond to those threats” (Al-Awadi, & Renaud, 2007, p.3). This paper will discuss a few aspects that are involved with firewalls and intrusion detection systems.

Almost all kind of large and small organizations might face increasing number of attacks into their network or intellectual property. This may lead to data disclosure, data destruction, and damage of organization’s reputation. There are numerous threats in the cyber space which might be capable of stealing, destroying or making use of out sensitive data for financial and non-financial gains. As the amount of computer, mobile and internet users increases, so does the number of exploiters.
