Discuss about the MN692 Capstone Project. The Internet and computer networks are increasingly exposed to security threats. When there are new types of attacks that occur constantly, the development of flexible and adaptive security-oriented approaches is a serious problem. In this context, a network based on anomaly intrusion detection methods are a valuable technology for protecting target systems and networks against malicious activities.

Types of Intrusion Detection Systems

Intrusion Detection Systems are security tools that, like other measures such as antivirus software, firewalls, and access control schemes, are intended to strengthen the security of information and communication systems. Over the years, several IDS approaches have been proposed in literature since the creation of this technology, two highly relevant works in this direction reddening [3].

An intrusion detection system (IDS) can be considered an application which is associated with monitoring a network or systems for detecting various kinds of malicious activity or policy violations. Various malicious activities or violations are typically reported either to the administrator or are generally collected centrally by making use of a security information and event management (SIEM) system. The SIEM system is associated with combining the outputs from multiple sources, which is followed by the usage of the alarm filtering techniques in order to distinguish the various type of malicious activity from the alarms that are false.

There exist several types of IDS, and this scopes from a single computer to a widespread network. The most common Type of IDS includes the “network intrusion detection systems” (NIDS) and “host-based intrusion detection systems” (HIDS). The system which is associated with monitoring the important operating system files can be considered as an example of a HIDS, whereas a system which is associated with the analysing the network traffic which is incoming can be considered as an example of a NIDS. The IDS can be classified according to the detection approach that is used amongst which the most well-known variants include the signature-based detection or recognizing the bad patterns, such as malware and anomaly-based detection or the detecting deviations from a model of "good" traffic, which often relies on machine learning. Some IDS have the ability to respond to detected intrusions. Systems with response capabilities are typically referred to as an intrusion prevention system.

Network intrusion detection systems (NIDS) has been placed at a strategic point or points inside a network for the purpose of monitoring the traffic that is generally towards or from all devices connected with the network. This is generally associated with performing an analysis of the traffic that is passing on the entire subnet, which is followed by matching of the traffic which is generally passed on the subnets to the library of known attacks. After the identification of the attack or abnormal behaviour is done, then an alert is sent to the administrator. (An example of a NIDS would be installing it on the subnet where firewalls are located in order to see if someone is trying to break into the firewall. Ideally one would scan all inbound and outbound traffic, however doing so might create a bottleneck that would impair the overall speed of the network.).Some of the common tools used for simulating network intrusion detection systems mainly includes the OPNET and Net Sim. This type of Systems is also capable of comparing signatures for similar packets in order to link and drop the harmful detected packets that are consisting of a signature matching with the records in the NIDS. When the classification of the design of NIDS is done according to the system interactivity property, then it can be concluded that there are two types and this mainly includes the 5fon-line and off-line NIDS, which are often referred to as inline and tap mode, respectively. On-line NIDS is associated with dealing with the network on a real-time basis. This is also associated with analysing the Ethernet packets along with the application of some rules in order to decide if it is an attack or not. Off-line NIDS are associated with dealing with the stored data, which is initially associated with the passing of it through some processes in order to decide if it is an attack or not.

Network Intrusion Detection Systems (NIDS)

NIDS monitors the traffic that is headed towards the main system using applications. It can be used either software or hardware based. It creates alert to the admin when the attacker tries to enter the system.  NIDS detects different kinds of attacks that try to enter into the main system. There are several applications used in order to detect network intrusions, snort is one of the major tools which is used to detect the intrusions and alert it regularly. As these tools are open source and easy to install on any network which is cost-efficient. Snort is mainly based on the rules which are stored in a file name called local. Rules which can be customized according to the user requirements. It reads the customized rules and applies it to the captured data.

There exists various kind of techniques in the literature for detecting the behaviours related to intrusion. In recent times, intrusion detection has been associated with receiving a lot of interest amongst the researchers and this has mainly happened due to the wide application of this for preserving the security within a network.  Here, we present some of the techniques used for intrusion detection.

  1. F. Owens and R. R. Levaryhas been associated with stating the fact that the intruder detection systems have been commonly created by making use of the expert system technology. However, the Intrusion Detection System (IDS) researchers have been associated with biasing which is generally related to the construction of the systems which are generally difficult to handle, along with lacking in insightful user interfaces, besides this, they are also very inconvenient for usage with real-life circumstances. The adaptive expert system proposed by them has been associated with the utilizing of fuzzy sets in order to detect the attacks. Besides this, the implementation of the expert system can be considered as comparatively easy while using it with computer system networks which have the capability of getting adjusted to nature or to the degree of the threat. Experiments with Clips have been used have been used for the purpose of proving the adjustment capability of the system. A researcher Alok Sharma did the usage of text processing on system call sequences technique for only intrusion detection. To have a host-based intrusion detection kernel based comparison measurement is used. K-nearest neighbour is used for processing to check if it’s normal or abnormal classification [11] in 1998-DARPA has assessed the proposed method and compared with present methods for operation.
  2. Shanmugam and NorbikBashah Idris have been related to proposing a progressive fuzzy and data mining approaches which were built upon the hybrid model in which both the misuse and along with anomaly malware attack. The goals of this researchers mainly included the decreasing of the quantity of data that is generally kept for the purpose of processing and also for the purpose of improving the detection rate of the existing IDS by making use of the attribute assortment process and data mining method. An improved Kuok fuzzy data mining algorithm or a modified version of APRIORI algorithm is generally used for the purpose of utilizing and also for the purpose of implementing fuzzy rules which have been associated with enabling the generation of if-then rules that are associated with showing the best possible way to process the attack.

To test and benchmark the efficiency of any model use DARPS 1999 dataset which include the live results of the working networking environment.)

  1. A. Adebayo has presented a method that uses Fuzzy-Bayesian to detect real-time network anomaly attack for discovering malicious activity against a computer network. They have established the effectiveness of the method by describing the framework. The overall performance of the intrusion detection system (IDS) based on Bayes has been improved by a combination of fuzzy with the Bayesian classifier. In addition, by the experiment carried out on KDD 1999 IDS data set, the practicability of the method has been verified. Abadeh, M.S., and Habibi, J. has proposed a method to develop fuzzy classification rules for intrusion detection use in computer networks. The method of fuzzy rule base system design has been based on the iterative rule learning approach (IRL). Using the evolutionary algorithm to optimize one fuzzy classifier rule at a time, the fuzzy rule base has been created in an incremental fashion. Intrusion detection problem has been used as a high-dimensional classification problem to analyse the functioning of the final fuzzy classification system. Results have demonstrated that the fuzzy rules generated by the proposed algorithm can be utilized to build a reliable intrusion detection system [13].

           Network Intrusion Detection Systems (NIDS) generally consists of a network appliance (or sensor) along with a Network Interface Card (NIC) which is generally responsible for operating in the promiscuous mode along with working in a separate management interface. Placing of the IDS is done in association with the network segment or boundary along with the monitoring of all traffic present in that segment. Network intrusion detection system (NIDS) can be considered as an independent platform which is associated with identifying the various intrusions by examining the traffic in the network along with monitoring of multiple hosts. Network intrusion detection systems are associated with gaining access to the network traffic by creating a connection with the network hub. Additionally, the network switches are also configured for mirroring the ports, or for the network tap. Along with this in a NIDS, the sensors are generally present at the choke points of the network which are to be monitored, often in the demilitarized zone (DMZ) or at network borders. The Sensors are associated with capturing all the network traffic along with analysing the content of individual packets for the traffics which are malicious in nature. 

Detection Approaches

Above figure illustrates elementary diagram of the project, it explains the project methodology of how a NIDS is placed to capture the traffic and detect the intrusions and avoid the malicious traffic. NIDS is placed between firewall and host.

The key approaches to detect an attack is by using signature and anomaly-based detection. The anomaly is based on the behaviour of the traffic and whereas signature based is on the previous attacks.  Anomaly evaluates asymmetric patterns of the activity. Misuse which is signature based detects the known attacks through the signatures that are stored in the database. Anomaly detection technique builds profiles according to the behaviour of network traffic, users, and hosts.

Snort is all about network security. The user has developed snort IDS for network analysis attack and also relate to the current work and then analysed with wire shark. Attacks are classified on the basis of profile and then the comparison is made with the scoring accuracy which is improved than current attacks. It produces alarm only one time instead of making again and again. There are rule categories of SNORT and it gives the greatest performance in updating all rules [18]. It also gives an evaluation of all rules and also confirms that his verified snort IDS can identify the high percentage of network attacks. Also clear that users must update their snort rules frequently. As a future work, we can say that if we identify other types of network attacks like teardrop attack, DoS, DDoS and data alteration with existing method than there could be further room for the research

The project's goal is to find a way to escape the most vicious intruders. This can be done by implementing NIDS, which needs to be updated according to the present situation. These can be done by analysing the packets that are captured by using techniques such as identification, vulnerability and risk calculation. Our project, therefore, aims to preserve the concept and its function of the system for detecting and preventing network intrusion and network security by analysing incoming and outgoing traffic. Predefining set of rules in our operating firewall this helps the firewall to build in identifying different types of attacks. The main objective is to identify the threat and protect the sensitive data from the intruder. NIDS is programmed to differentiate between valuable data with help of identification strings.

  • Capture, analyse and deliver report using signature and anomaly-based detection system.
  • To implement NIDS that can detect any irregular network traffic in the network by analysing the header file, port no and address.
  • Storing all the details of the attacks that are being happened before for the usage of signature-based detection technique.
  • Create a system which helps to detect security threats in a network.
  • Launch a new system in a network to decrease the attacks.
  • A network-based IDS scanner secures the whole network by detecting the missing packets, open ports and security breach.

Network Intrusion Detection System (NIDS) is advanced protection which examines network activity to detect attacks or intrusions. NIDS systems can be hardware and software-based devices used to examine an attack. NIDS products are being used to observe connection to detect whether attacks have been launched [20]. NIDS systems just monitor and generate the alert of an attack, whereas others try to block the attack.

Snort as a Rule-based IDS

The network intrusion detection systems can detect several types of the attacks that use the network. NIDS are excellent for detecting access without authority or some kinds of access in excess of authority. A NIDS does not require much modification for production hosts or servers. It benefits because these servers regularly have the closed operating system for CPU and installing additional software updates may exceed the capacities of the system. Most NIDSs are quite easy to deploy on a network and can observe traffic from multiple machines at once [21].

We are using Snort for the network intrusion detection system. Snort is primarily a rule-based IDS. It can perform real-time traffic monitoring, analysis and packet tracing on Internet Protocol (IP) networks. Snort reads the predefined or customize rules at the start-up time which can be predefined or customized and builds internal data structures or chains to apply these rules to captured data. Snort is available with multiple sets of pre-defined rules to detect intrusion activity and you can also free to add your own rules as per the requirement. Below is the block diagram for the snort architecture.

The network intrusion detection system (IDE) is a system that supports in identifying numerous attacks within the network system. IDS can be located on any network that helps in gathering data and information for providing good security to the networks. Rules are mandatory to perform recognition of attacks in a network system. The Next Generation Intrusion Detection Expert System (NIDES) has helped in keeping the security of the network system by using the analytical and statistical model. The use of IDS has assisted in maintaining the security of the data and information on the network server of the company [22].

Packets are being captured and evaluated through snort, snort performs defragmentation of IP packets and logs all the packets that are captured. It does packets sniffing, logger and full functional NIDS. Snort detects and reports the attacks regularly using signature and anomaly-based detection techniques. If any malicious data is detected; it detects the malicious packets and stores it in log file [23]. On the bases of the fresh attack, its profile is updated by a new rule and using these approach new attacks can be discovered.

In this Method, the set of data is separated into a testing and training.  The method includes the detection technique with the help of known and unknown attacks.  Hybrid based NIDS includes both anomaly and signature-based to detect the attacks. All the attacks that are being detected by anomaly are saved as signature-based in the database so that it can be detected in the future. When the packets enter the system it is being analysed with signature-based technique and then forwarded to the anomaly, anomaly analyses the behaviour of the traffic and detects the attacks.

Windows should be used to implement Snort. The process is made painless and easy by Windows – easier than to install Snort as well as to configure Linux server. Snort sensors must be seen as apparatuses (such as UPS or a router) and hence, do not require to coordinate with the server infrastructure. Actually, one presumably has other system apparatuses running on some versions of Linux. One final thought is if ones' intrusion detecting framework is on a similar platform like the rest of the frameworks, it might progress toward becoming compromised alongside different systems in case of an effective intrusion.

For minor fittings, a single PC can house the organization applications (ACID and Snort Center and) screen the network. In bigger organizations, one will presumably need to isolate these capacities. One PC can play out the administration roles while different PCs acts like sensors. Windows is intended to give a safe, lightweight condition and, in this way, runs just a negligible arrangement of ordinary Windows services [24].

Network intrusion detection system, virtual box is installed in the computer in order to simulate the process. Windows is used as the main platform in order to perform. Windows 10 OS is installed in virtual Box, after installing windows snort is being installed and configured according to requirements in order to monitor incoming traffic. Honey D is being deployed in the system in order to capture the attacker's details. All these applications are being installed to neutralize the attacks using algorithms.

Snort is being deployed to monitor the malicious traffic using signature and anomaly-based detections, it displays required information regarding the incoming and outgoing traffic that is being captured by the wire shark and analyses the traffic by using algorithms. All these applications are being deployed inside the OS and incoming traffic is being monitored regularly.  Nmap is being used to scan all the open ports and start the attack.

As per above fig, This pie diagram illustrates around 31 percent of malware detection in comparison to 21 percent of trojan activity in the network there are a percentage of successful attack 6 percent and 3 percent unsuccessful attacks on the network using NIDS

In this above bar diagram the type of attacks that have been happened until now through various interfaces or applications.  Browser attacks are one of an easy way to attack a system and the least type of attacks is back door, scam, and DNS attacks.

  • Data packets’ confidentiality
  • Access control in the network
  • Outgoing and incoming transmission of the data packets.
  • Accessibility of services.
  • Snort’s functionality.
  • Check for available services.
  • Check hacker's action from public networks that are entering into private networks.

Network intrusion detection system plays a major part in the field of network security, they provide a high layer of security to the main system from suspicious activities or patterns and alarms network administrators when a suspicious traffic is being detected. Snort was mainly implemented or designed to neutralize this issues.

Snort is being configured as a NIDS (Network Intrusion Detection System). In order to detect the known and unknown attacks by saving the attackers signature.  To provide security against port scanning from the attackers and restricting the traffic from different networks, used two different windows systems one for the attacker and other as a victim or the main server [25].

Identifying ping scan

As the attacker starts to identify the host status by sending the ICMP, TCP, and UDP packets using the command ping scan by assigning destination IP  address so in order to neutralize the attack a rule needs to be assigned in the snort.

Snort is the most effective application or a tool in order to detect the malicious traffic by assigning rules. Traffic is being analysed through snort and can be implemented in a network.

Alerting  icmp packets

Alert icmp any any -> any any (msg: “Testing ICMP alert! “; sid:1000001; )

Alert TCP any any -> any any (msg: “Testing TCP alert! “; sid:1000002; )

Alert UDP any any -> any any (msg: “Testing UDP alert! “; sid:1000003; )

The above rule needs to be implemented in the local. rules file in order to intimate the attack.

C:usersserver>cd snort

C:snort> cd rules

C:snortrules> local.rules

After assigning the rules to use the following command in order to test the configuration that is being added. Use ping command by assigning the destination IP address from the attacker's system by executing the following command in the main server all the ping scan that is being performed on the main system is stored in log file.

C:Snortbin>snort  -i 2 –c  C:snortetcsnort.conf –A console >  c:snortlogpingscan.txt

Testing from attackers windows system by using destination ip address

Port scanning is used to probe host for the ports that are open and perform the attack by knowing the ports which are active to receive the traffic. This port scanning process is done by NMAP which is an application, designed in order to perform the port scanning on the destination host, often used by network administrators to secure the network by restricting the traffic.

Nmap for windows

After installing NMAP, use following Commands for nmap port scanning

C: > cd “Program Files <86>”

C: Program Files <86>> cd Nmap

C: Program Files <86>Nmap> Nmap –T4 –A –v 192.168.0.9

Nmap port scanning using destination IP address

As the system is being tested with various types of attacks such as port scan nmap, ping test all the packets are being captured by a snort and being shown in the output.

All the details are being stored in a log file in snort including date time and type of packets that are being entered into the system.

This is intended to recognize any intrusion into the network with an aim of deciding and giving affirmation that there is no any point of intrusion into the system from an external system. This additionally assists to identify the attempted attack. Along these lines, the snort ought to have the capacity to distinguish the attempted hacking.

The concentration in this structure is to look at the activity of snort in a remote sensor system to recognize arrange attack by use of WIDS. Adequate outcomes will be received from the way snort is composed, installed, and designed in the Remote Network that protects the system from any intrusion or attack. The snort structures execution, dataset employed as well as the testing ought to encourage adequate outcomes to be acknowledged in WIDS found on the server that have different standards and guidelines.

The report demonstrates that several forms of intrusions are noted after the installing snort, firewall, as well as other safety devices that assist in detecting the attacks.

From the alarm. Ids file demonstrates Rremote Procedure Call (RPC) a threat based on the buffer overflow exploitation which is categorized as miscellaneous activity and ranks it as lower level insecurity as per the WIDS snort standards-based ranking. The enemy executing attacks to a host with an Internet Protocol Address of 192.168.120.100 aiming host with an Internet Protocol Address of 192.168.0.128 that in this circumstance is the mail server. Port 52 is the one that is being used, where snort cannot detect. Port 53 is then open, where backdoor attacks use to survey network services categorized as attempted proprietor privileges gain the Priority. This indicates that the enemy has administrative rights, therefore can fully access the network services [26]. TCP is the protocol used in this situation. When an administrator receives the report, it is easy to screen all traffic through TCP port-52 implementing the principle on Snort.

The point of applying death of ping attacks is to test whether snort has the capacity to recognize the traffic from public and internal network. The apparatus went to the installed server by sending limitless data parcels. Central servers that are targeted should respond to every ping packet directed to an internal system. Designed snort must stop the death ping after it shows up [27]. The command applied ping < IP target host> - t - 1 65500, will transfer packets at a speed of 125 lbs. Target hosts test is the mail server, IP address of 192.168.0.128 like demonstrated below:-

The report indicates that traffic timestamp, time, date, packets NETBIOS Unicode data have accesses categorized by the name generic protocol command on decode precedence, DOS, and SMB. Report evaluation demonstrates that alarm activities contained heavy traffic, from external and internal towards port 53 address 192.168.150.10, applied for NETBIOS.  Services of NETBIOS are used to let communication in internal LAN. The report offers details concerning the position of the host within the private network. Through port 53, traffic is noticed [28]. The other attacks include the Finger protocol, HTTP, and the Trojan horse.

WEKA

WEKA is a cluster of algorithms consist of a number of machine learning and data mining [29]. This has a GUI interface to cooperate with the data files, as this software is written in java language. It comprises15 attribute evaluators, 76 classification algorithms, ten search algorithms and 49 data pre-processing tools for feature range [30]. This software contributes with three algorithms to discover association rules. It has three GUI: "The Explorer", "The Experimenter" and "The Knowledge Flow."   The supporting file format for WEKA is ARFF stands for Attribute-Relation File Format. WEKA also contains tools for conception, as for the dataset the algorithm can be applied directly.

Why is WEKA data mining software used for?  The WEKA tool integrates these steps as follows:-[31, 32]

  • To evaluate the precision of any data exploration and pre-processing is a necessity in weka database.
  • Characteristic of a class is to divide the classes accordingly to its occurrences.
  • Abstraction of any features for the using of classifying.
  • To use the subset of the classes should be used for the decision learning process.
  • It's always better to check for any out of place dataset and how it can be re-corrected.
  • When a subset is selected for the classes that are put in the records for the learning process.
  • Any testing method will give an approximate performance from the algorithm selected.

In weka, the classification of the data is an algorithm in data mining which is used for intrusion detection system to differentiate any attack or intrusion from the regular effects that happen in the system of weka. The classify algorithm are administered knowledge approach, as weka doesn't involve class names for any of the prediction goal. There are two types of classification algorithms which are the main in class which are one binary classification and another one is multiclass classification [33]. The binary classify method is a classification of the element in two groups on the foundation of whether they have some distinctive or not. Whereas the multiclass classify technique of classification occurrence into more than two classes. The natural binary algorithms whereas all other which permits the application of more than two classes. Here is some of the following classification:

The naïve Bayes is the latest upgraded version of the Bayes theorem as it’s considered to be a strong deliverance among attributes. Bayesian classifier encrypts probabilistic associations amongst variables of interest. The meaning of this is the probability of one attribute which won't affect any other probability of any other attribute. Network intrusion detection system based on naïve Bayes algorithm the proposed a framework Mrutyunjaya Panda and Manas Ranjan Patra [34]. The method naive Bayes is a set of supervised learning algorithms based on applying "Bayes" theorem with any if the "naïve" supposition of individuality among every pair of structures

The most known machine learning techniques are by Quinlan which was proposed a decision tree classifier [35]. The decision tree is a collection of three elements,

  • To test or condition on a data item a decision node is represented.
  • To correspond to one possible test outcome attribute to the possible attribute value which is an edge or a branch.
  • The object belongs to the class only when the leaf is controlled [36].

The Decision tree is a classifier algorithm

  • The decision tree is used to build the training. The tree of each node of the attribute of data we choose one node and then we split the sample set into subsets to other improved in one class or the other.
  • The normalization is a condition that any decision tree is based on by selecting the attribute from splitting data and getting the results. To make a decision any attribute with the highest normalized information gain is preferred.
  • For every attribute, the gain is considered and the maximum gain attribute is used in the decision node. There are six of the decision tree algorithms to examine an in weka which are J48, J48 Graft, Simple chart, Rep tree, Random forest and Random tree and also different gain results [37].

Technique Result (Accuracy) Correctly Classified Instances Incorrectly Classified Instances 98.5983 % and 1.4017 %

A promising pattern classification technique is support vector machine (SVM) [38]. In the last decade for the misuse detection, SVMs have supervised learning models which are related to the knowledge that has been functional increasingly. The latest SVM learning algorithms are called as SMO (Sequential Minimal Optimization). The support vector machine learning algorithms were using numerical (QP) quadratic programming for the inner loop, whereas SMO uses an analytic QP step.

Conclusion

The aim of this report was to decide the viability and execution of the intruders detecting system:  Comparing it with the outstanding IDS, Snort, is a quick system. Snort was evaluated on different steps on super PCs with different conventions and packet sizes as well as protocols. A huge amount of packets reduces while using virtualization resulting from changing aspects of virtualization where the assigned physical memory RAM to the host PC is a distributed disc space as well as virtual RAM. It will respectfully impact the function and creates packet drops. As the number of packets received by the network card gets higher than the amount received by virtual machines, this thought is conceptualized due to the bottleneck resulting from the exchange of low circle data [22].

In this project, the design and development of network intrusion tool help to detect the attacks regularly and intimate the network admin and keeps the system secure without any issue. Data mining techniques are being implemented dynamically in IDS and capable of generating real-time results.
