The last two attacks that can damage the network in different ways is Trojans and worms, I will start off with Trojans how Trojans inter the network is when a person downloads free software or programs to the system and they is a Trojan with them, this is why it is very hard for anti-virus software to find and damage the Trojans. The Trojans attacks the network by modifying blocking and even delete data. The last attack that I will describing is Worms, worms and viruses are similar in the way how fast they spread through the network, worms also fill up the storage space with junk the result of this slows down the
Obtaining certification in a specialty area is one way a nurse confirms she has achieved the necessary knowledge and skill within that practice area to be considered above average (Rauen, Shumate, & Gendron-Trainer, 2016). In order to realize my goal of board certification as a master’s prepared informatics nurse, I must first gain the required education, expertise, and competence through classes and practice experiences. This paper will discuss how each MSN core course, each MSN specialty course, and each potential practice experience will improve upon the competencies needed to obtain board certification in informatics after obtaining my MSN from American Sentinel University.
Infection control refers to action devoted to policies and procedures that reduce the risk of spreading infections, reduce the occurrence of diseases caused by bacteria and viruses, parasite. The infectious diseases are normally spread by human to human, human to animal contact or by ingestion of food, droplet in the air, and contact with a surface that is the vehicle of the infective agent. H1N1, commonly known as the swine flu, a viral infection, was a cause of 2009 world-wide pandemic. The virus was first found in pigs, but a similar virus also found in humans. The virus spreads in a same manner as any other seasonal flu, mainly by droplets (small particles in the air) when an infected person coughs, sneezes or even talks, but also by touching
Infectious diseases are the invasion of host organisms, (microbes) which can be invisible to the eyes. The microbes are also known as pathogens. A microbe infects an organism (which is known as the host of the microbe). In a human host, the microorganism causes a disease by either disrupting an important body process or by stimulating the immune system to mount a defensive reaction. The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death. The host's response to infection is inflammation. An interaction between parasite and host, whereby the relationship is beneficial for the former but detrimental to the latter, is characterized as parasitism.
Can destroy all of the data and erase all of the file or misused by the attacker.
This unique characters, otherwise called signatures can be a byte pattern in the virus. This is usually done using the AV software, the AV software uses the signature obtained from the signature database to detect the malware, and when a match is gotten, the AV software then alerts and prompts the user to repair or remove the file.
With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders. External intruders are individuals who are not authorized to access the system and attack it using various techniques. Internal intruders are individuals who are authorized to access the system but perform unauthorized activities on the system. An IDS watches activities performed on the network and searches for malicious
It is a type of security software which is identifying the malicious activities and later on, it finds the person who is trying to do malicious activity. For example, an insubordinate employee gives all information about a customer to another company without permission which is illegal. Also, he shows his dishonesty to his company. Therefore, the intruder detection system will be able to protect the information.
Using the experimental setup, Spyeye, Blackenergy, Zeus, Athena and Andromeda botnets are installed. Zeus, ZeuS, or Zbot is a Trojan horse malware package that runs on versions of Microsoft Windows. While it can be used to carry out many malicious and criminal tasks, it is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing. It is also used to install the CryptoLocker ransomware. Zeus is spread mainly through drive-by downloads and phishing schemes.
A threat is a constant danger to an asset, whereas a threat agent is what facilitates an attack.
Network Security refers to any activities that take place to protect the network; more likely to protect the usability, reliability, integrity, and safety of the network and data. Targeting the threats and stopping them to enter or spread on the network is the job of effective network security. Most common threats for any computer networks are:
People from different sections of the universe are interacting, collaborating, socializing and doing other different activities via internet, which in turn exposes their personal information in cyberspace. Lack of knowledge and cyber security awareness makes these people to be vulnerable to hackers and other malicious players who use the cyber environment. These has been supported by Furnell, Bryan, Phippton, (2007) when they argued that personal or individual internet users are highly exposed to security threats while using their own home computers. It is therefore important that internet users should have clear understanding of all the risks of using internet, the importance of protecting their personal information and the outcome if this is not done
The operation was code name Buckshot Yankee. Operation Buckshot Yankee was the United States response to the terrorist attacks of 2008. Unlike the terrorists’ attack on 9/11, the attack on 2008 was a cyber-attack that affected the U.S Government’s unclassified and classified computer networks. The Deputy Secretary of Defense William J. Lynn III (2010) stated “It was a network administrator 's worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an unknown adversary”. The program that infected the Government’s networks was a computer worm, a type of malicious software (Malware) that duplicates itself without human interaction, called Agent.btz. Ellen Nakashima (2011), a National Security reporter
Lets meet the “OSX/Oompa-A” also known as the first mac os virus. On February 16, 2006 SophosLabs had detected and announced that they had founf the first mac os virus. This virus is clever because it runs through the Macintosh iChat instant messaging system it starts by forwarding itself as a LATESTPICS.TGZ file on the contacts of a infected user. When opened it shows a .JPEG file picture which tries to trick the user into believing it’s a legit file. The virus uses the "OOMPA" text as a point in the forks of the infected program which prevents it from infecting the same files. People in the Macintosh community have gone back and fourth about this virus debating if it a virus or a Trojan horse.to give you a idea what a Trojan horse looks like I will give you a example. So my friend Billy has given me a file that says freeavastantiviruskeygen.exe and told me it was a program that he designed himself so that he could give people free premium keys for avast I say ok and open it.nothing happens so I try again same thing nothing happens.my computer starts moving the mouse by its self and all my accounts get locked out. That is what a Trojan is it has key loggers the hacker can move the mouse just like he is in your home and he can do what he want with your computer. Delete files, create them, look through your webcam, steal passwords, and more. OSXLeap-A on the other hand is made for the IChat messaging system and replicates its self and sends its self through the I chat messaging system and tries to get users to open the file up to infect them.so technically this virus would be considered a worm. The reason I say it would be a worm would be because it spreads its self from victim to victim but it also needs someone to open it each time for it to spread even more.(
According to CDC -The social determinants of health are the environment, conditions and system in which people are born, live and work. These environments are formed by a different forces that have a direct influence on the status of health such as economics, politics, and social policies.( Centers for Disease Control and Prevention). Many different factors have direct impact on state of health of individual, such as: diet, sex, age, smoking and alcohol use, income , environment where person live, insurance coverage and access to healthcare services ( quality ) and education level, social support, community safety. All these factors significantly contribute to well and how long we live. For example of how Social determinants can affect health - premature or low birth weight baby can be result of low income, low education level, alcohol use, inability to access prenatal care, environment where mother live, poor diet.
