The goal of Clark Consulting remains to help develop a more secure network for Harry and Mae’s Inc. in that vein, Clark Consulting has determined some final additions and changes to the Harry and Mae’s Inc. network. The additions include a Bastion server, Network Intrusion Detection System (NIDS), Host Intrusion Detection System (HIDS) and a Security Information and Event Management (SIEM) server. The changes will primarily revolve around passwords. The webserver will be placed in a protected area, called a Demilitarized Zone (DMZ), outside the corporate network. The DMZ will be protected by a hardened firewall server called a Bastion server. The Bastion server’s services are limited and the configuration is changed to make the server …show more content…
The analysis will allow the NIDS to alert on activity which could be a sign of unauthorized access or malicious activity. The IT security team will check the alerts to determine if an event or incident has occurred. Similarly, an HIDS application will be installed on all servers and workstations. The HIDS application will analyze the servers and workstation and check the system logs to determine if any potential unauthorized or malicious activity has occurred and send the information to the NIDS for processing and alert creation. The SIEM is a log management system where every network device, server or workstation will send their logs for storage, correlation and analysis. The analysis will provide alerts similar to the NIDS and HIDS. In addition, the log correlation could be used to help track where and when malicious activity has occurred and on what system(s) the activity was seen. The combination of the NIDS, HIDS and SIEM will provide a good array of detection for malicious users, software or unauthorized system access. The password related configuration changes which are recommended below will make it more difficult or unauthorized users to figure out user passwords and access systems with the identified
IDS is a device or software application that monitors a network for an unauthorised attack.
Software application development at my company was initiated first out of security concerns. There were increasing numbers of security breaches reported in hospitals, banks, Yahoo, and other places that paused potential hazards (Snyder, 2014). We are in the financial Industry with huge volumes of sensitive data. Our Information Technology department expressed concerns that our SQL server was an easy target to those that may want to hack the system. Existing security measures and periodic training were very strict but they were not enough to protect customers from hackers.

During my undergraduate time, I would work as a supplemental instruction (SI) leader for calculus 1 and calculus 2. Now, I am working at Laredo community college as an SI Coordinator for a grant. I was learning about the concepts of SI where I learn about Revision of Bloom’s Taxonomy. “The RBT consisted of two dimensions namely the Cognitive and Knowledge dimensions” which goes from lower to higher thinking (). The six categories that have a sign in learning for students remember, understand, apply, analyses, evaluate, and create. These same categories are what we use to conduct SI sessions, but we might use three of them which we go from lower to higher thinking. As an example, my session for calculus three would start from remembering of
This week in my HUMI 1 class, the one topic that we discussed in class that captured my attention was the state of being Naiveté. Although being naive is often looked down upon, it can also be something that you require in order to achieve your goals. When looking into the topic of Naiveté, the first person that I went to was my father. He was a refugee after the Vietnam war in 1975. Vietnam, even to this day, is not a place that many would want to live in. According to my father, during his time there, it was a filthy place to live and everyone there would often get sick. People were forced to work to exhaustion and starvation and diseases were the main causes of death. While all of this was occurring, he and his friends would often talk about

The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.
Lastly, the application layer (Layer 7) supplies services to application procedures and threats are static passwords and SNMP private community strings (Holl, 2003). Organization will need to enforce encryption to limit the exposure of personal information, ensure that patches are installed for applications, patching and is performed on all network and hardware devices, hardening of operation system and implements secure authentication methods (Baker & Wallace, 2007). Additionally, a quality anti-virus is utilized on workstations, servers and other devices connected to the organization IT infrastructure. All types of attackers discussed in this paper are applicable. Black hat hackers and cyber terriorist will control exploit vulnerabilities in networks and application systems that are not properly patch as well as malware writer
Due to their complexity and importance to information security, two security systems, Network Intrusion Detection/Prevention Systems (NIDPS) and Security Information and Event Management systems (SIEM), will be explored in this paper. Both have multiple functionalities, including threat-detecting capabilities, and are widely considered essential tools for adequate network defense, particularly in the goal of fortifying valuable assets in the face of an advanced threat. Understanding these systems is vital for any security operation tasked with defending significant networks.

Analyses to determine the effect of proposed changes on existing security controls to include the required training for both technical and user communities associated with the change in hardware/software.
Easy information access also opens the door to numerous security threats. The job of the enterprise network management team is to detect and respond to all the potential threats in a quick and decisive manner. While most network security systems can do this, there are some disadvantages associated securities in network

Security is typically handled by a system administrator who implements the security policy, network software and hardware needed to protect a system and the resources accessed through the network from unauthorized access and also ensure that employees have adequate access to resources. A system security typically relies on layers of protection and also consist of multiple components includes networking monitoring and security software. All components work together
