Network intrusion detection system

environment is based around a static defense that has been employed for the past few years to protect information systems (See Figure 6). Unfortunately, this cybersecurity paradigm is not effective against current and future cyber threats. According to Zheng (2014), the weakness of this cybersecurity approach is its passive and reactive nature towards safeguarding information systems. Additionally, this method also allows threat actors the time they require to conduct their reconnaissance and…

Cyber deterrence has been thrown out in the public, governmental, and military sectors for the better part of the first half of the decade, stretching into discussions currently in organizations like NATO, and governments worldwide. The theory is simple: “deter someone from doing something out of fear of repercussion or retaliation.” Theory and concept however, are very different premises and conclusions. Everyone in the information warfare area knows that attribution is a slippery slope, and…

should have a goal of protecting all three facets. According to Shon Harris, the confidentiality portion of security is defined as preventing unauthorized disclosure of sensitive information, integrity is preventing unauthorized modification of systems and data, and availability is preventing the disruption of service and productivity, ensuring that the data is not lost or stolen, remains intact and not tampered with, and is always available (2002). In an effort to promote these best practices…

It starts from monitoring organization’s network, their network traffic, gaining access to confidential information and exfiltrating that information (Lord, 2016). Microsoft and Adobe Flash APT attack: Recent Microsoft and Adobe Flash vulnerability attacks that was carried out by Russian group was a zero…

The study also explains the fact that for most healthcare organizations the confidence level in its employees to actually notice a data breach is next to none. If they can’t detect the breach then they are not capable of notifying anyone in the event of one. A data breach can go undetected for quite some time before anyone is even aware of it. Another problem is there are so much time and money spent on policies and procedures and not enough money spent on enforcing them. It is important that…

Traditionally, power grid architectures were standalone systems that consisted of proprietary protocols traversing legacy hardware and software systems (Li et al., 2012). Power grid automation systems using this type of architecture carried high operating costs that power companies found to be inefficient over time (Kuder et al., 2010). Due to this inefficiency, power companies began to integrate the operation of power grid automation systems into public networks. This integration served its…

Some organizations still use outdated machines because they cannot afford to upgrade. It is not in their budget, so Microsoft systems that run 2003??? May still be infected with the Conficker virus. Conficker affected Windows 2000 Service Pack (SP) 4, Windows XP SP2 and SP3, Windows Server 2003 SP1 and SP2, Vista Gold SP1, Windows Server 2008 and Windows 7 systems. It then patched the “hole” at Port 445 to inhibit other malware from exploiting the system’s vulnerability (Krepinevich, 2012).…

In its beginning, the Internet was much slower than it is today, requiring companies to host their own networks in order to interconnect their computer systems. As the Internet continues to evolve and become faster with each passing year, the ability has emerged for companies to cut costs by offloading their networks to companies who host these services over the Internet. This practice has widely come to be known as Cloud Computing. The benefits of such a service are many, but it does come with…

than the testing system. None of the phases are carped more than the testing of being carried out at a substandard level. In most cases, IT and management try to reduce the project’s cost through reducing testing. Phase seven is the implementation of SDLC. In this phase the system needs to ready for implementation. But before this can be done the user acceptance must sign off. This requires documentation which includes the user acceptance report (Aras & Ciaramitaro, 2008). System…
