Intrusion Prevention System

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

For the purpose of this assignment snort will be used as intrusion detections systems which is an open source IDS, snort has the ability to monitor traffics in real time and packet locking its also inspecting each packets as they enters into the network, Snort can be used as packet sniffer to analyse the network traffic in order to detect any bizarre looking packets or payloads which might have malicious data in it. Snort can also detect payloads attacks against the network or host system including but not limited to stealth port scan, and buffer overflows.

As part of the network security team, we will be proving IDI with a network security plan to mitigate the vulnerabilities that have been discovered. A secure site will be set up with network intrusion detection and network protection systems will be available to access via the internal network. Policies will be presented for remote access and the use of VPN. Also contained within this report will be strategies for hardening the network and mitigating risks. An updated network layout with increased network security to meet the current needs will be included.

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?

The IPS and IDS systems will be another addition that will be used to protect the Riordan Manufacturing networks as well. There is a difference between these two systems and it is important to know what each one does. The IPS stand for Intrusion Prevention System. This system is designed to prevent attacks from hitting the network. For the new Riordan network the IPS system that will be implemented is Surefire because use a rule based detection engine known as Snort.

In D&A case, an IPS (Intrusion Prevention System) would have helped because an IPS helps in limiting the Zone transfer and segregate authoritative servers. While traffic enters into the networks, an IPS will inspect the type of traffic and frequency of traffic and will permit, deny, or alert depending on the set up. It will help prevent in ICMP flood, DNS flood, and DNS spoofing in the network. An IPS will match against pre-set rules or dynamic signatures to detect malicious patterns. One of the most popular types of DNS attacks, called Cache Poisoning Attacks, can be mitigated by the implementation of IPS. But I wonder how correctly and effectively D&A implemented their IPS in their networks. Just installing firewall and/or IPS will not prevent unauthorized access from intruders. The sustainability of cybersecurity systems after initial implementation is significant. In my recent experience, after cutting-over a company’s network and installing firewall with IDS and IPS features, I emphasized the importance of monitoring the traffic frequently and build the security rulesets accordingly to deny or permit or alert the type of traffic that goes in and out of the

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:

Cybersecurity is a top priority for just about every organization. But given the rapidly changing cybersecurity landscape, even the most seasoned and well experienced teams have a tall task in front of them to keep up. Furthermore, Advance Research Corporation faced multiple Denial of service attacks a few years back, which defaced the organization from the successful attack. It is important that Advanced Research Corporation conduct penetration testing on a standard basis, so vulnerabilities present on the hardware and software of the company may be detected. Also, to help check, which security protocols have been installed correctly and help determine if the system is vulnerable to malware and bugs in the current software. This proposal

Based on our experience with this project, it is clear that the risk of network attacks is very real and should be given significant attention by a company to prevent any serious damage resulting from such attacks. We have a few points that would make sense for a company to implement in order to reduce risk.

As the network usage in the real time business applications is more, Aruba focusing on increasing the security including intrusion prevention system (IPS) which is the embedded mobility firewall system.

Firewalls is categorized as a preventive control which is used as a defense shield around IT systems to keep intruders and hacking from occurring, whereas, an Intrusion Detection System (IDS) which is categorized as a detective control is used to detect intrusions that have already occurred (Cavusoglu, Mishra, & Raghunathan, 2005). However, IDSs are not

It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security

Abstract: Providing security in a distributed system is important as cloud computing provides variety of convenient services. IDS implementation in cloud requires an efficient, scalable and a constructive approach. Many Network-based intrusion detection systems(NIDS) are used for the reception of packets from the cloud, but those systems possess lower detection rate, high false positive rate and they fail to resist single point attack. I would like to propose one method which I encountered and found out to be efficient compared to other methods. This unique model has multiple intrusion detection systems (IDSs) that are deployed in each layer of the cloud infrastructure for protecting each Virtual Machine against threats. Another catching feature is that of cloud alliance concept which exchanges mutual alerts to resist the single point attack of failure.

We design a service in the P4 Controller, that can detect and prevent a DOS attack using a multi-layer firewall approach and the packet counters available inside the P4 firewall. This service is also leveraged to enable a Honeypot intrusion detection-prevention system.
