Every web server poses a risk to network security threats. One of them is a threat of Slow HTTP Attack. Slow HTTP Attack exploits the working methods of the HTTP protocol, where it requires that every request from the client be fully accepted by the server before it is processed. If the HTTP request is incomplete, or if the transfer rate is very low, the server remains busy waiting for the rest of the data. If the server is storing too many busy resources, there is a denial of service. Internet users can exploit such vulnerabilities,  send incomplete data packets deliberately and requests repeatedly. When a web server is in a public network or the Internet, then protecting computer and network security is an important issue. After identifying and analyzing how the Slow HTTP attack works, as well as its attack detection, this paper describes portfolio of the work system , how to detect and how to defence against the Slow HTTP attack. Keywords— Slow HTTP Attack, Web Server Exploit, Denial of Service, DoS

INTISARIKeamanan jaringan pada web server merupakan bagian yang paling penting untuk menjamin integritas dan layanan bagi pengguna. Web server sering kali menjadi target serangan yang mengakibatkan kerusakan data. Salah satunya serangan SYN Flood merupakan jenis serangan Denial of Service (DOS) yang memberikan permintaan SYN secara besar-besaran kepada web server.Untuk memperkuat keamanan jaringan web server penerapan Intrusion Detection System (IDS) digunakan untuk mendeteksi serangan, memantau dan menganalisa serangan pada web server. Software IDS yang sering digunakan yaitu IDS Snort dan IDS Suricata yang memiliki kelebihan dan kekurangannya masing-masing. Tujuan penelitian kali ini untuk membandingkan kedua IDS menggunakan sistem operasi linux dengan pengujian serangan menggunakan SYN Flood yang akan menyerang web server kemudian IDS Snort dan Suricata yang telah terpasang pada web server akan memberikan peringatan jika terjadi serangan. Dalam menentukan hasil perbandingan, digunakan parameter-parameter yang akan menjadi acuan yaitu jumlah serangan yang terdeteksi dan efektivitas deteksi serangan dari kedua IDS tersebut.Kata kunci: Keamanan jaringan, Web Server, IDS, SYN Flood, Snort, Suricata. ABSTRACTNetwork security on the web server is the most important part to guarantee the integrity and service for users. Web servers are often the target of attacks that result in data damage. One of them is the SYN Flood attack which is a type of Denial of Service (DOS) attack that gives a massive SYN request to the web server.To strengthen web server network security, the application of Intrusion Detection System (IDS) is used to detect attacks, monitor and analyze attacks on web servers. IDS software that is often used is IDS Snort and IDS Suricata which have their respective advantages and disadvantages.The purpose of this study is to compare the two IDS using the Linux operating system with testing the attack using SYN Flood which will attack the web server then IDS Snort and Suricata that have been installed on the web server will give a warning if an attack occurs.

Detection Effect

Software Defined Networking (SDN) is one of the most commonly used network architectures in recent years. With the substantial increase in the number of Internet users, network security threats appear more frequently, which brings more concerns to SDN. Distributed denial of Service (DDoS) attacks are one of the most dangerous and frequent attacks in software defined networks. The traditional attack detection method using entropy has some defects such as slow attack detection and poor detection effect. In order to solve this problem, this paper proposed a method of fusion entropy, which detects attacks by measuring the randomness of network events. This method has the advantages of fast attack detection speed and obvious decrease in entropy value. The complementarity of information entropy and log energy entropy is effectively utilized. The experimental results show that the entropy value of the attack scenarios 91.25% lower than normal scenarios, which has greater advantages and significance compared with other attack detection methods.

Distributed Denial of Service (DDoS) is a type of attack using the volume, intensity, and more costs mitigation to increase in this era. Attackers used many zombie computers to exhaust the resources available to a network, application or service so that authorize users cannot gain access or the network service is down, and it is a great loss for Internet users in computer networks affected by DDoS attacks. In the Network Forensic, a crime that occurs in the system network services can be sued in the court and the attackers will be punished in accordance with law. This research has the goal to develop a new approach to detect DDoS attacks based on network traffic activity were statistically analyzed using Naive Bayes method. Data were taken from the training and testing of network traffic in a core router in Master of Information Technology Research Laboratory University of Ahmad Dahlan Yogyakarta. The new approach in detecting DDoS attacks is expected to be a relation with Intrusion Detection System (IDS) to predict the existence of DDoS attacks.

While Internet has opened a whole new world of opportunity for interaction and business by removing many trade barriers, it has also opened up new possibilities and means of criminal acts altogether unheard of in the off-line world. Why do people commit crimes online? Perhaps, some of them attempt to gain unauthorised access to other’s money. Some people have fun doing so and there are others who do it to take revenge or to harm others. While the motivation of conducting criminal acts may be the same as in the off-line world, the manner of such criminal acts is unique to the Internet. The vulnerability of the information transmitted over Internet is the root cause of the sprawling of criminal acts over Internet. Both users and vendors become vulnerable to criminal acts that undermine security due to easy accessibility of Internet and easy exploitation of security loopholes in the Internet. These criminal acts can adversely affect Internet users, particularly online vendors and customers. Therefore, it is important that Internet users not only become conversant of such criminal acts but also take suitable measures to counter and avoid becoming victims of these criminal acts. In this article we examine some of the major information security threats to Internet users with particular emphasis on electronic commerce and propose plausible solutions for a safer online experience. The information security threats can be categorised into threats to the users, threats to the vendors, and threats to both users and vendors. Electronic embezzlement, sniffing and spoofing, and denial-of-service attacks are examples of threat to the vendor. Credit card frauds and malicious codes are examples of threats to the users. Cybervandalism and phishing are examples of threats to both users and vendors.

Network security is now increasingly needed in the era of the industrial revolution 4.0. As technology grows, cybercrimes are becoming more and more common, including attacks on a resource. At this time, honeypots are also widely used by large industries for network security, besides that honeypots are also useful for them in developing intrusion and preventing systems. Honeypots are usually used in a virtual environment, they will stimulate a fake system to capture data packets on the network and be analysed offline later for all threats and attacks. This propose of this paper is to detect and prevent building attacks from computer network attackers using an android application. This application can monitor an attack on the server by installing a honeypot tool into the server as an attack detector, then the honeypot log is used as a Rest API using Django framework with MongoDB database. this application can find out if there is an attack on the server, and can block the attacker's IP address.

<p>In recent, the high available internet service is main demand of the most people. However, online services occasionally become inaccessible due to various threats and attacks. Synchronization (SYN) flood Distributed Denial of Service (DDoS) is the most used and has a serious effect on the public network services. Hence, the outcome of this attack on the commonly utilized cluster-based web servers is systematically illustrated in this paper. Moreover, performance of Internet Information Service 10.0 (IIS 10.0) on Windows server 2016 and Apache 2 on Linux Ubuntu 16.04 server is evaluated efficiently. The performance measuring process is done on both Network Load Balancing (NLB) and High Available Proxy (HAProxy) in Windows and Linux environments respectively as methods for web server load balancing.  Furthermore, stability, efficiency and responsiveness of the web servers are depended as the study evaluation metrics. Additionally, average CPU usage and throughput of the both mechanisms are measured in the proposed system. The results show that the IIS 10.0 cluster-based web servers are more responsiveness, efficiency and stable with and without SYN flood DDoS attack. Also, the performance of IIS 10.0 web server is better than of the Apache 2 in term of the average CPU usage and throughput.</p>

TCP SYN Flood as one kind of Denial of Service (DoS) attack, still popular to flood the server connection, by sending SYN packets to the target. Because of the risk caused by this attack, there is a need for a network security mechanism. In this paper, one of the security mechanisms proposed is using Stateful Packet Inspection (SPI) method on Configserver Security and Firewall (CSF). By using SPI method, CSF has capabilities to responsible for separating packets of data, that may be entered with data packets that should not be entered into the server. For example: port to be opened, port closed, and IP Address that may access the server for anywhere. This paper combines both of CSF and SPI method to prevent TCP SYN Flood (DoS) with Proof of Concept (PoC) at the Linux operating system. The security process is done in 3 ways: configuring a maximum connection from an IP Address to a server, securing an incoming SYN packet per second, and counting how many times an IP Address violates the minimum SYN packet rule per second before being blocked by a firewall.
