Network Security And Situational Awareness Data Pre Processing Method Based On Conditional Random Fields

tools will help to detect intrusions and other suspicious activities on the network. The third challenge is to improve the

Incident response and planning is very critical to a business. It’s important Greiblock Credit Union (GCU) financial firm maintain control of these incidents in a timely manner which could reduce cost, and risks. When responding to incidents one should always minimize the severity of all security incidents. The analyst should have a clear plan to resolving incidents, while containing the damage and reducing risks (Cichonski et al., 2012). According to Cichonski et all, (2012) most departments have a Computer Security Incident Response team, or designated personnel to handle the variety of incident responses related to Cyber Security. Based on the below, the information can be used in a technique to help an organization to determine the threat against the organization and identify if it’s truly a security breach or serious

This study investigates how knowledge in network operations and information security influence the detection of intrusions in a simple network. A Intrusion Detection System (IDS) was developed to examine how individuals detect malicious events and declare an attack based on a sequence of network events. The results indicate that more knowledge in cyber security facilitated the correct detection of malicious events and decreased the false classification of benign events as malicious. While knowledge of cyber security helps in the detection of malicious events, situated knowledge regarding a specific network at hand is needed to make accurate detection decisions. Responses from participants that have knowledge in cyber security indicated that they were able to distinguish between different types of cyber-attacks, whereas novice participants were not sensitive to the attack

The Intrusion Detection System (IDS) is a protection scheme which collect and analyze audit data for the entire network.

Computer security is a critical issue for nearly all businesses today. Threats to security have become more pervasive, more dangerous, and more damaging to the health of businesses. Being able to appropriately respond to a security breach is essential to the long-term success of any business. Incident response planning is necessary before an incident occurs. In their publication, Computer Security Incident Handling Guide (Special Publication 800-61, Revision 2), the National Institute of Standards and Technology (NIST) has made recommendations on the phases of incident response, what types of tools can be useful to a team responsible for incident response (IR), and what documentation is needed as part of the response. This paper discusses these topics as endorsed by NIST.

These proposals and systems suggestions can minimize the vulnerabilities associated with any compromises or intrusions within the network. Deploying an intrusion detection system is an essential security strategy for monitoring a network information system for abnormal or authorized activity. An intrusion detection system (IDS) is set of tools which monitor a network topology by providing a system administrator with the overall picture of how the system is being utilized. Executing an IDS will make a difference in creating a defense in depth architecture to be more compelling in recognizing any form of malicious activities. The capacity of the IDS is to monitor and survey the network traffic without affecting network activity. IDS tools gather information and analyzes it against a pre-characterized manage set, and against a set of known assault 'marks'. The IDS can scan port numbers and to determine if any breaches or attacks are occurring (Kuipers,

The Questionnaires and information gathering documents are very important because they provide accurate information about the security of the system and where improvements can be made to prevent further intrusions and remediate certain vulnerabilities within a system. The inputs for this step include reports from prior

Incident response procedures and supporting enterprise systems need to be defined and installed. A great cyber security incident management system, which includes incident tracking as well as addressing the requirements of data breach and forensics investigations. It provides a solution which covers threat intelligence, malware analysis, and operational feeds, as well as workflow automation of the

Incident Response (IR) is “where personnel move to further identify the scope of the threat in the network and follow response procedures to contain and eradicate”. A key element in almost all incident response systems is the collection and presentation of potential incident information, more usually described as threat intelligence, which comes with two problems. First, the overall volume of data presented by incident response systems, and secondly the isolated manner in which the intelligence is reported. A common response from CISOs is that “I don’t need more intelligence, I just need better intelligence.” That “better” intelligence also needs to be “usable” intelligence by different security controls. It is of little surprise that the

Incident response is defined to be a process (i.e. written instructions) in which an organization utilizes for detecting, responding and managing data breach or cyber attacks with the goal to effectively limit the effects of the incident so that damage is minimized and both recovery time and financial costs are kept to a minimum. This process involves figuring out what happened and preserving information related to those events [14]. A key element in almost all incident response systems is the data collection of potential incident information this is designated as threat intelligence. This introduces two problems with the first being the overall enormous volume of data presented by incident response systems. The second problem is the isolated

Perception for interruption location helps a security head to perceive irregular conduct in an intuitional way. Representation of interruption location empowers quick examination and reaction in light of the fact that an interruption is perceived intuitionally. In this way, it can overcome alarm flooding. Most interruption discovery strategies with perception are peculiarity based identification systems and envision review information as opposed to the ready itself. [5].The host-based perception strategy for interruption discovery is to learn ordinary conditions of recognizes or projects that is accomplished by the client and contrasts review information and profiles for representation.

Abstract: In this real world, protecting the information of an organization that is present in a software and hardware or data present on them is important. Here comes the point of Threat Intelligence, where it recognises the disruption or misleading of the service provide by these data present on the software and hardware in the form of accessing through network, code injection, data injection, hacking of the sites, controlling through physical access or by any means of taking control over the data. Simply, Threat intelligence is the set of data collected, assessed and applied regarding security threats, threat actors, exploits, vulnerabilities and compromise indicators. It is usually presented in either the form of strategic or tactical intelligence. Strategic intelligence involves broader and higher-level abstracts of data to identify threats and how the organization needs to react where Tactical intelligence involves collecting the network information, analyzing it, identifying the threats and responding. By using of this it makes cost effective to organization by reducing security incidents, which increases responsive time by finding solution in a least possible time. It also shows the security incidents, attacks and events. It provides decision support to the organization and possibly a strategic advantage. Threat intelligence also involves series of steps which make the data to be gone through several phases starting with collection, then planning, process, produce

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:

This paper explores two references that report the Defense in Depth Strategy created by Intel in order to be better prepared for a possible network attack. According to the website “Defense in Depth Strategy Optimizes Security” Intel created the strategy by developing a solution broken out into four separate categories: “Prediction” which prepares the organization for possible attacks as well as what kind that may happen. The second category being “Prevention” allows ways that could prevent the attack by being prepared. The third category is “Detection” allows the organization to receive an alert if there is a possible attack. Finally, the fourth being “Response”. This strategy provides the time needed to respond to a possible attack. Due to these strategies, there has been a reduction in attacks. The website “Security Awareness - Implementing an Effective Strategy” (2002), IT Security Mangers will need to be effective when implementing the above named strategies. Establishing security needs as well as providing security awareness training to employees.

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.
