Intrusion Detection System Essay

Challenges to baseline analysis include simplifying the data for better analysis, dealing with large-size packet capture files, and working with multiple tools to gain an accurate perspective on the network. It is important to know that base lining is not a one-time task, but a regular part of network monitoring.

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.

VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].

2. Active Attack: Active attacks are those attacks where the attacker takes malicious action in addition to passively listening to ongoing traffic e.g. attacker might choose to modify packets, inject packets or even disrupt network service. The misbehaving node has to bear some energy costs in order to perform some harmful operation like changing the data. Active attacks cause damage and are malicious which often threaten integrity, availability of the network. These type of attacks can be internal or external [7].

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.

Network Intrusion Detection: Software exists to watch traffic on your network to search for malicious intent. Is an Intrusion Detection System going to be implemented? An IDS is not a fire and forget type system. It requires constant monitoring. Smaller organizations will be overwhelmed by the amount of information it produces.

The fifth domain is the WAN domain. In this domain, the network security application that is apart of it is the intrusion detection system/intrusion prevention system (IDS/IPS). This device monitors the system for malicious activities and reports it back (Kim & Solomon, 2012). The WAN Domain connects to remote locations and using the IDS/IPS is crucial because it will help to remote if any outside activity is trying to access the system that should not be.

Finally, gathering all this information would enable the network administrator adjust the IDS to attacks specific to the network.

The network team is doing its part to recommend updates to the network intrusion detection system. Also the team has setup alerts which will send email to the team when there is a change in the baseline network bandwidth which can be a precursor to an attack. Additional monitoring has been enabled to alert the team when there is administrative access to the firewall. Also the team will work to build resiliency in the network to automatically switch the network to additional circuits when under this type of

AV detects the specific types of unauthorized activities within the forms of mischief mobile code, communally known such as malware. When describing intrusion detection systems, it possibly makes sense to define what they remain not to be. IDS’s are not preventive measures. They won’t stop intruders from breaking into systems. Neither prevents internal damages to the systems. They’re detection systems, recognizing exploitation of the system then reporting them as it transpires.

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.

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

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.

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
