Denial of service (DoS)- This type of attack occurs when a hacker overloads a server or network device with numerous IMCP (Internet Control Message Protocol) ping requests, such that it is unable to respond to valid requests. By updating to the latest service pack and applying security patches, you can minimize the threat of DoS attacks by reducing the vulnerabilities in the TCP/IP network protocol. Although disabling ICMP can remove valuable troubleshooting tools, it can effectively remove the possibility of DoS attacks. Also, any firewall or security software should be configured to recognize and block these attempts if possible.
Back door- In a back door attack, a hacker exploits a coded “opening” in an application that allows them access to the user’s computer. By educating users to be wary of unknown email sources, attachments, and pirated software and multimedia, you can minimize the possibility of incidents of Trojan Back Door software being installed. Closing unused ports, maintaining updated anti-virus definitions, and running personal firewall software can also reduce the threat of back door software.
Null sessions- A NULL session is an attack that exploits weaknesses in the NetBIOS networking protocol. By utilizing Windows XP version or later on PC’s (or switching to Mac! Haha!) and making registry changes to require authenticated users, you can effectively remove the possibility of null sessions.
Spoofing- Since spoofing refers to devices that are external to your network mimicking an internal address, configuring your firewall to deny external packets from sending from internal network addresses will prevent this type of attack.
Smurf attack- By disabling broadcast addressing on the router, you can eli...

On August 12, 2003, a computer worm was released called MSBlaster.B, which was distributed through two files “teekids.exe” ( which included code that directs compromised computers to attack the Microsoft domain name www.windowsupdate.com and a backdoor file “Lithium” ( which allows a way into a password protected system without use of a password and remote control a system). The worm itself targeted mostly Windows 2000 & Windows XP systems. If Windows NT or Windows 2003 servers do not have the appropriate patches, they too may be vulnerable. The function of the worm is to exploit the DCOM RPC vulnerability.
These warnings can help users alter their installation’s defensive posture to increase resistance to future attacks. An intrusion detection system is comparable to a burglar alarm system. The car locks to protect the vehicle from theft. In the event someone compromises the lock, the burglar alarm detects this compromise and alarms the owner.
Unlike many other attack types used by hackers, DoS attacks do not seek to steal information, break into systems or escalate privileges. A DoS attack is used to deny services of a network resource, such as a web server. According to Vangie Beal, “This type of attack is essentially designed to bring a network to its knees by flooding it with useless traffic” (2010). Various tools can be used to perpetrate a DoS attack including Internet Control Message Protocol (ICMP) echo requests, R-U-Dead-Yet (RUDY), Dirt Jumper, and virus/worm programs which automate an attack.
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.
Security is a wide concept, it is a separated subject with its own theories, "which focus on the process of attack and on preventing, detecting and recovering from attacks" (William 1996). Certainly, these processes should be well organized in coping with the complex system issues. A coherent approach should be taken, which builds on established security standards, procedu...

Would you be interested in a career where you could make fifty thousand dollars a year right out of college? Would you like to have an extremely secure job? Would you like to create a company as successful as Microsoft or Facebook? If so, a career in computer security may be the field for you. As a high school student, you might be wondering what it would be like to work in the field of networking or database security, as well as compare them to similar fields. Today I will give you some general information that might encourage you to seek a degree in the field of computer science, with a concentration in computer security. My goal is to give you information to help you make an informed decision about whether this might be the career for you.
Denial of Service attacks (DoS) or Distributed Denial of Service Attacks (DDoS), have been around for many years, but only in the past few years have the frequency and magnitude of these attacks increased. They are a significant problem because they can shut an organization off from the Internet for extended periods of time and little can be done to stop them. DoS attacks occur when computer resources become unavailable to legitimate users after being exhausted by false requests for information (Houle and Weaver 1).
iPremier once suffered a denial of service attack on 12th January 2007 that almost rendered the company’s site nonfunctional (Austin, 2007). Denial of service attack can be defined simply as an attempt to prevent the availability of computer resources to its legitimate users (Encyclopedia Britannica). This is achieved through halting an internet site or service from working efficiently, temporarily or permanently. Hackers had launched the denial of service attack on iPremier but luckily it was launched either by a script-kiddie or a competitor trying to ...
Throughout the world computer networks are becoming more popular as more and more technology is being implemented into organizations in order to help employees process their work, and communicate with one another. Along with the ever growing technology the more possibilities of data and information getting stolen or lost by hackers attempting to access the networks in an organization. There are many systems out there that will help detect and alert an organization of the attacks or prevent attacks from happening. Systems known as intrusion detection systems (IDSs) and intrusion preventative systems (IPSs) do exactly that for an organization and when they are combined are known as Intrusion detection and prevention systems (IDPSs).
If you are considering using the Internet for a service that is absolutely time- or mission-critical, you should consider your fallback position in the event that the network is down or damaged. Microsoft has released hotfixes that address certain types of denial-of-service attacks such as SYN Flooding and giant Ping packets. Be sure to regularly watch for new Service Packs, because they offer new security enhancements that you should put on your systems.
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...
Risk management has been one of the major concerns of executives and professionals involved with projects today, especially after the financial crisis that shook the world in 2008.The results of ex-post assessments of project or even verification of lost business opportunities for companies are clear signals that this evidence has become more intense (Junior, 2013).
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
When planning a new project, how the project will be managed is one of the most important factors. The importance of a managers will determine the success of the project. The success of the project will be determined by how well it is managed. Project management is referred to as the discipline that entails the processes of carefully planning, organizing, controlling, and motivating the organization resources so as to foster and facilitate the achievement of specific established and desired goals and meet the specific criteria of success required in the organization (Larson, 2014). Over the course of this paper I will be discussing and analyzing the importance of project management.
