Network attack detection

In this study, we propose a method for generating mutated Windows malware against malware detection based on ensemble learning by combining GANs and RL to overcome the limitations of the MalGAN model.

In this article, we have researched, compared and evaluated current methods for solving problems such as data augmentation, data generation via generative networks and classing importance control. Additionally, we will also provide a brief overview of existing datasets for intrusion detection in wireless networks.

Research Aims: The thesis aims to develop deep neural networks for analyzing security data. These techniques improve the accuracy of machine learning-based models applied in NAD. Therefore, the thesis attempts to address the above challenging problems in NAD using models and techniques in deep neural networks. Specifically, the following problems are studied.

Security Attack: Any action that compromises the security of information. Security Mechanism: A mechanism that is designed to detect, prevent, or recover from a security attack. Security Service: A service that enhances the security of data processing systems and information transfers. A security service makes use of one or more security mechanisms.

Used to communicate IP status and error messages between hosts and routers Uses IP to route its messages between hosts Must be implemented with IP remember, IP is just a packet delivery system transmits and routes datagrams from sources to destinations through a series of interconnected networks it has a checksum in the IP header to detect lost bits no error detection on the datagram payload though but has no native mechanism for source host notification This is where ICMP comes in its used to report IP errors to the source host ICMP data is carried as the payload of an IP datagram specifie...

The “2000 CSI/FBI Computer Crime and Security Survey,” conducted in early 2000 by the Computer Security Institute (CSI) with participation by the San Francisco office of the Federal Bureau of Investigation (FBI), showed that 90 percent of survey participants from large U.S. corporations, financial institutions, medical institutions, universities, and government agencies detected security breaches in 1999. About 70 percent of the participants experienced breaches more serious than viruses or employee Web abuse.

Greetings. This is the oldie, but goody section of the course. This next section is important for a number of reasons. If you think about it, attacks occur in stages. In general the attacker has to perform reconnaissance to hone in on the target, to find the weaknesses. Then there will be an initial attack, this is often minimal, in the book Network Intrusion Detection we referred to this as the “grappling hook”. Finally, the attacker completes the kill. This attack shows each of these stages. This attack took 16 seconds to complete.

While insider attacks may cause more damage (because the attacker knows the system assets and what to target), insiders are also usually addressed by traditional security and audit. An insider has a much greater chance of being caught, since you know where they live. So while damaging, insider attacks are infrequent (because of the high risks of detection and arrest or dismissal), by contrast, it is extremely difficult to track and prosecute attackers arriving over the Internet. And because of the perception of low risk, attacks are a daily or hourly occurrence....

In our next section we are going to introduce network-based intrusion detection. The detect engine in this case is either a firewall, a personal firewall, or an intrusion detection system. All of these work quite well. We will begin with a single attack, just to see how one might work and how we might detect it. Then we will explore the range of tools and show you how you can get in the game with a very low investment, possibly even free.

Host-based intrusion detection could also be called host-specific intrusion detection, in that its primary purpose is to detect suspicious activity or known attack patterns on the specific host it is installed on. Some host-based intrusion detection systems (HIDS) have a number of host detectors reporting to a central management console that can flag alerts, centralize logs, and update the host detectors’ policies. Other HIDS are stand-alone.
