...Importance of Firewall MedIQ is going in the right direction by adding a firewall in their network. The importance of a firewall is that it blocks malware that would be able to scan your computer to find its vulnerable areas and then attempt to break it while it is at its weakest point. First of all there is only one way to make your computer completely safe from attack and that is either when it is off or unconnected from the Internet. Other than that there are always vulnerabilities. However, you can make it as close to hacker proof as possible while it is connected to the Internet. The way to do this is to have a personal firewall installed along with antivirus and anti spyware protection. Plus you have to make sure that all three of these are updated on the regular. Additional protection is available to a network that used a router with a firewall feature. Firewalls protect your computer from outside attacks by guarding it from unnecessary Internet traffic. They can however be configured to block certain data while letting other data in. The importance of a firewall on your computer can not be underestimated especially for those who are always connected to the Internet. Firewalls are positioned between your computer and your network and are great for protecting multiple computers but also offer a great degree of protection for single computer use. It allows individual users decide how much content they want to filter through and what websites are safe to use. In some...

...software firewall as well as hardware firewall in one device called cyberoam as well as MacAfee anti-virus . A firewall is a system designed to prevent unauthorized access to or from a private network.It is located at a network gateway server. A firewall plays an important role on any network as it provides a protective barrier against most forms of attack. It controls the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set by the organization using. There are two types of firewall: * Software Firewall: Is a software program installed in any computer in order to protect it. Software firewalls is best suited for protecting computers from Trojan programs, e-mail worms, or spams. It prevents any unauthorized access. An example of software firewall includes Zone Alarm, Sygate, Kerio. An illustration is shown below: * Hardware firewall: Is a device which connects your computer or network in order to protect them from unauthorized access. An example of hardware firewalls includes Linksys, D-Link, Netgear. There are several types of firewall techniques but the one which is used by Dar Al-Hekma College is Packet filter technique. This technique as its name implies filters all the packet data that enters or leaves the Dar Al-Hekma college network and it then decides whether to accept or reject it based on the configuration set by DAH College. Hence the firewall in this...

...Joseph W Costa LOT2 Task 2 5/24/2013 Best Practices in Prevention of DoS/DDoS Attacks This guide is meant to describe best practices for the detection and prevention of denial of service attacks, such as the event that recently occurred at the university. It was determined that based on current security guidelines and current controls in place, the university was still severely vulnerable from an internal aspect and all identified gaps need to be addressed and resolved. Each control described below will provide a more in depth look at the overall strategy of how a network should be protected but still allow for the functionality that is required to maintain normal operations. Know the Signs of an Attack An essential part of network security is knowing what the characteristics of an attack are, so they can be countered or prevented. When the university suffered an overwhelming internal DDoS attack, it required administrators to reevaluate its security guidelines based on what was known about the attack. As seen at the time of attack, certain characteristics were: Network performance unusually slow Website was unavailable for at least 24 hours Thousands of bogus HTTP packets sent to internal web server Taking these factors into account, it can be safe to say it was an actual attack rather than just legitimate network usage. Now that it is known what such an event would look like, identifying similar attacks in the future will be much easier and may allow...

...conducted in Phase 1, and proposes possible changes in order to ensure the safety of AS networks. The Company owns an enormous production plan which promises to deliver high quality solutions for targeted at various industries. It is equipped with a team of excellent and highly qualified professionals who cater to various needs of different industries. This paper intends to find possible solutions to bridge the gaps as found in the investigation in Phase 1. The weaknesses that are being addressed are the firewall configuration, virtualization of their hardware assets and defining and revisiting their security policy regarding firewall configuration and updated software at least twice a year. Brief overview of the Vulnerabilities in AS After a thorough investigation of the IT architecture and systems of the Aircraft Solutions, two main concerns were identified as the priority items that needed attention. The first was hardware related concern and was pertaining to the lack of a firewall being present in the network. This would lead to high risks as the system would be vulnerable to malicious attacks from external users, and also due to lack of any authentication mechanism, authorization of inbound traffic, there was always a possibility of information loss or damage. Another major concern was related to the software policy of AS. As per...

...were presented. With the information provided, and based on additional research, the primary objective in this assessment was to identify the possible presence of vulnerabilities within the overall framework of Aircraft Solutions operations. Based on the presence on weaknesses, an evaluation of the associated threats was conducted, followed by an analysis of any risks that may be present and potential outcomes. Overview Three areas of potential security weaknesses in Information Technology (IT) for Aircraft Solutions, or any company are hardware, software, and IT policy. In terms of hardware, the provided Network Architecture Map detailed that Aircraft Solutions lacks a firewall between the Commercial Division and the Internet, while all other branches of the company are protected through a firewall in one manner or another. This is a significant vulnerability to the entire system. For Software, Aircraft Solutions uses a Business Process Management System (BPM) that handles end-to-end processes across multiple systems and organizations within in the company. Currently their software solution seems segmented, with many steps required before it allows not only user access from internal customers, but external customers’ as well. So multiple users access the software solution which coupled with the Hardware vulnerability could lead to potential disaster....

Opening the attachment by the users would place some type of spyware to get habits and web activities. 3. Eventually I could land with some valuable information that would affect the individual’s privacy and confidentiality. Then I could have gain access to the system. Next phase of attack: • Use hping/2 to test the firewall, hping offers an IP spoofing scan while monitoring a target’s response to seduce discovery information such as distinguishing between different firewall policies and active services. • I would use Nessus Security Scanner with a tool providing a Scripting Language (NASL) to write a security test based on my findings on the weaknesses of my network. • Another technique is the use of Nmap for scanning the network and single hosts. I would try the stealth ability of Nmap to bypass firewalls scanning all different protocols UDP, TCP, or ICMP. Ultimately the combination a set of tools would give me an idea about how a hacker can coordinate its intrusion to the...

...Area of System Threats Potential Vulnerability Website Network Service DoS Attack Denial of Service attack will slow the system down considerably or cause the whole network to not function at all which will deny customer access to the service Database Back-door Attack A back door is a means of access to a computer program that bypasses security mechanisms. This is when the hacker places a back door that could be done by installing a program that can give the hacker unlimited access to the database anytime which could compromise any important data. Email Phishing Attacks Phishing is a form of fraud in which the attacker tries to learn information such as login credentials or account information by masquerading as a reputable entity or person in email, IM or other communication channels Summary The three areas that Team D considers the most threatening is the website network service, database, and email. The security in these areas must be up to date as hackers are constantly trying to obtain access to the company’s information. The new customer rewards program allows for information of customers to be at risk if not properly secured. The data that will be saved in the database is the customer’s name, address, DOB, phone number, email address, and account number. Therefore, the importance of keeping this information secured is high priority. According to US CERT (2013),” [DoS attack is] …targeting your computer and its network connection, or the computers and network...

...AIU ENG 107 INDIVIDUAL PROJECT 5 DARRIUS HUGHLEY 12-2-2012 Intro Even though there are some downfalls with having too strong of a firewall or polices; is not being able to access certain websites, databases, and not being able to access the internet or intranet at all that you normally access. The major downfall of having the proper network security is the cost of it. Examples of expenses are but not limited to software, sonic walls, firewalls, and even a trained professional to maintain it all. When it comes to security you will have to be numb about the expenses of it. Failure to keep your network secure and or well maintained could lead to costly consequences legal wise, and repairs. To avoid bad things from happening it would be wise to make this investment. Thesis Having a secured network is very crucial for today’s society. And also make sure that the network security is strong enough to prevent their information from being accessed by anyone other than them. Online privacy is another issue that we are facing as well. The Internet has given people the ability to shop, pay bills, and etc. And people and businesses need to make sure that their network are secured. Body Having a secured network will keep you safeguarded from threats. Threats such as security breaches, viruses and data loss are the main threats to a network. For example this virus called the Conflicker had affected late last year computers worldwide. What worries security experts...

...Packet Filtering Index Should arriving packet be allowed in? Should a departing packet be let out? Filter packet-by-packet, making decisions to forward/drop a packet based on: Functions of Packet Filter Control: Allow only those packets that you are interested in to pass through. Security: Reject packets from malicious outsiders Watchfulness: Log packets to/from outside world In a software firewall, packet filtering is done by a program called a packet filter. The packet filter examines the header of each packet based on a specific set of rules, and on that basis, decides to prevent it from passing (called DROP) or allow it to pass (called ACCEPT). There are three ways in which a packet filter can be configured, once the set of filtering rules has been defined. In the first method, the filter accepts only those packets that it is certain are safe, dropping all others. This is the most secure mode, but it can cause inconvenience if legitimate packets are inadvertently dropped. In the second method, the filter drops only the packets that it is certain are unsafe, accepting all others. This mode is the least secure, but is causes less inconvenience, particularly in casual Web browsing. In the third method, if the filter encounters a packet for which its rules do not provide instructions, that packet can be quarantined, or the user can be specifically queried concerning what should be done with it. This can be inconvenient if it causes numerous dialog boxes to appear...

...Vulnerability Assessment Penetration Analysis A. Memo For Record: IDS upgrade or replacement Summary of Events: The health care clinic’s network security appliance (combined router/firewall/wireless access point) was hacked and passwords were cracked. Configuration changes to this device opened the network to a Denial-of-Service (DoS) attack. The result of this attack prevented access to patient records and insurance claims as part of their daily routine. The network Intrusion Detection System (IDS) sensor had been previously disabled because of degradation of network performance caused by the device. No advanced notification of system degradation caused by the DoS attack was identified until employees were unable to use the network to perform the jobs. IDS Definition: Network IDS is part of the external boundary protection and monitoring system. Threats to the network from external sources are identified and reported using a management console. With the sensor disabled attacks against the network can be accomplished undetected and reduce response time. “An intrusion detection system (IDS) is software that automates the intrusion detection process. An intrusion prevention system (IPS) is software that has all the capabilities of an intrusion detection system and can also attempt to stop possible incidents. IDS and IPS technologies offer many of the same capabilities, and administrators can usually disable prevention features in IPS products, causing them to...

...1. What caused the security breach at Hershey’s? Inside job The fact is that the biggest threat to an organization lies within its boundaries. In its 2006 survey, “Information Security Breaches,” the DTI and PricewaterhouseCoopers found that 32% of Information Security attacks originated from internal employees while 28% came from ex-employees and partners. Similarly, law enforcement experts in Europe and the US estimate that over 50% of breaches result from employees misusing access privileges, whether maliciously or unwittingly. So securing the enterprise isn’t just about stopping external threats. It’s just as important to contain the threat from hapless or hazardous employees. One of the key internal threats to corporates is spyware, because it’s all too often introduced without malicious intent, by employees that naively click through a couple of pop-up browser windows, or install an unapproved yet ‘cool’ application on the network. The situation isn’t helped by the myths that surround spyware. Human error, not technology, is the most significant cause of IT security breaches, according to a security survey released by the Computing Technology Industry Association Inc. (CompTIA) today. The survey, "Committing to Security: A CompTIA Analysis of IT Security and the Workforce," suggests more training and certification of IT workers will help the U.S. protect itself against cyberthreats. In more than 63% of security breaches identified by the survey's respondents, human...
