Computer security is very essential to proyect against the threats caused to computing system which happen because of it's vulnerability. Threat to computing security takes place by a person, event or circumstance may be intentionally for sake of finance or unintentionally by deleting some of the important data. A threat agent depends on method, opportunity and motivation. Method is a knowledge to attack , oppurtinity to access the necessary information and motive behind the aatack. In olden days during 1980's and 1990's it is done for the sake of personal fame, but in 2000's it is for financial purpose to gain profits. Cyber criminals are merging with established crime and espionage forces for the financial rewards. The misuse of internet has also increased drasticaly. Cyberterrorism is one of the biggest issue to hack a nations sensitive data and military plans. This attacks are also called as cyberwarfare of information warfare which are very difficult to trace out the identinty or the souce of origin at the point of attack. computer security safe guards the computer in three ways by failure of availibility, intengrity and confideliaty or privacy. Failure of availbility is the denial of service for which is a serious threat to life and society as now more are more dependent on computers. Integrity is the returning of programs exactly as what they are. Any modifications to programs must be made only by an authorized person to maintain the accuracy, quality and precisoin of the data. The third one is the privacy which is an inappropriate disclouser of data. A security policy is the one that defines the actions to be authorized, access to resources and what to be protected against what threat in order to achieve the ... ... middle of paper ... ...ection Systems supervise in order to warn about the attack which may be imminent, underway or has occured. Intrusion Prevention Systems operating like the detection systems identifying the ongoing attacks and also predict and stop the intrusion about to occur. Finally when the attack has occured the affected system will study the attack to know what has occured , how to prevent the eoccurence and the level of damage. The computer seience forensics study the attack and they act much like any other investigation system diong the assemblance of important piece of evidence and suggest the connections among the piece of evidence using their experience. The Computer Emergency Response Teams is also another organization dealing with security of computer by collecting data about vulnerabilities and attack patterns and warn them about the danger and possible counter measures.
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.
While there are several competing if loosely defined definitions of cyberterrorism, Hua and Bapta have clearly broken down the core elements to illuminate the nuances between traditional terrorism and an ordinary hacker. As Hua and Bapta aptly state, "modern economies are heavily dependent upon Information Technology (IT) based information systems for survival" (Hua & Bapna 2013). Given our dependence on Information Systems, some effort of consideration must be given to securing them.
Containment is the most important role to be played in an incident respond. These are the practice of the strategies which gets followed when there is an attack like Distributed Denial of Service Attacks ("Uf it security," 2011). In our Lockheed Martin company, we prepare ourselves for any circumstances so our employees can act upon the situation. Instead of wasting time in what needs to be done now we prepare ourselves for future attacks. The way containment process needs to be followed is to first determine which part of the system contains malware viruses and detecting this issue would be the first task in incident response strategy. The time when that one system is detected then our company will be isolating that specific system to limit
The attacks highlight the shortcomings in the system, trace them and correct the problem. Almost all major IT firms, defense systems and Cyber related organizations imply these methods in their security prevention mechanisms.
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.
Incident response is usually one of those security areas that tend to be impromptucompanies don't think about it until they have to. But that needs to change. In this paper I will discuss five steps - identification, containment, eradication, and recovery and follow up a business use to effectively response to a security threat and I will suggest four actions -use encryption and passwords, e-mail protection, install antivirus software, install workstation firewalls a businesses can take to effectively prevent a security incident in the future.
Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help to stop unauthorized users or intruders from accessing any part of a computer system. Detection helps one to determine whether or not someone attempted to break into a computer system, if they were successful, and what they may have done.
One efficient solution to prevent hacking is to install security programs. There are two types of security programs. The first type is antivirus program that software protects computers by inspecting every file and website, and if it finds virus, it will immediately deal with it. For example, Antivirus and Avira Antivirus Personal are such valuable programs that rea...
In reference to computer science, physical security is one of the most important accomplishments a business can achieve. Due to the advent of the modern technical age, all of a company’s records are held on their data systems. First and foremost, theft or loss of historical records and accounting data would instantly cripple an enterprise and could very well lead to its ultimate demise. The high profile news reports just in the last decade verify that. Hackers stole the financial records of several banks, which included the personal information of thousands of customers. Ditto for the Veterans’ Administration, for an employee’s laptop was stolen off site. Inside the computer’s hard drive were the ever important Social Security Numbers of hundreds of thousands of veterans and their families. For example, a financial institution goes to stark measures to ensure the money and securities stored there are safe. Not only are there outside locks on the doors and an elaborate alarm system, there is a fireproof steel vault with the finest timed locks available. Most usually, the valuables are further stored in locked boxes inside that vault. Just like that bank, an organization must strive to make physical security a priority. However, simply locking the data and equipment is far from sufficient. The information technology also needs an “alarm” of sorts, so that the company’s police, the information security specialists, can identify the threat and diminish or eliminate it.
It is an incredibly serious and growing threat, and in this attack the majority of the attackers are criminals, overseas adversaries, and terrorist. From the article, Understanding the Relationship between Human Behaviors and Susceptibility to Cyber Attack, by Aditya Prakash, “there are four distinct categories of users, gamers, professionals, software developers, and others.” This show the category of users using the computer. According to the Federal Bureau of Investigation, “Cyber intrusions are becoming more commonplace, more dangerous, and more sophisticated. Our nation’s critical infrastructure, including both private and public-sector networks, are targeted by adversaries.” Identically, in these attacks victims are the companies, universities, and the citizens, in most cases. For example, citizens are targeted by fraudsters, or in other words, by the overseas adversaries and identity thieves, and children, by online predators. Accordingly, for identity thieves stealing identities is increasingly being facilitated by the internet and so for the online
Crimes like the various forms of networking hacking existed before the technology boom, but with computers and other pieces of technology, these crimes became easier to commit and many times get away with. Cybercrime is a concern that has been attracting media attention since 1945, when the United Nations created an international cooperation and collective security network of 192 countries to cooperate and solve international problems and one of a growing issue is cybercrime (Portnoy and Goodman, 2009). Now that technology is developing fast daily, individuals and businesses are more likely to attain this problem. I could see that cybercrime will be the top threat to the United States. Not only our country but also the people of our
Computer crime or Cyber Crime is defined as any type of crime that involves or regards a computer or computer network. Cyber Crime mainly means that the computer may be used as a tool in the commission of the crime or the computer may be the main target of the criminal’s crime. The rapid growth of technology and gadgets as well as the further de...
Hardware, software and the data that resides in and among computer systems must be protected against security threats that exploit vulnerabilities. Organizations must therefore impose appropriate controls to monitor for, deter and prevent security breaches. Three areas have been considered, in a typical sense, as the basic critical security requirements for data protection: confidentiality is used to assure privacy; principles of integrity assure systems are changed in accordance with authorized practices; and, availability is applied to maintain proper system functions to sustain service delivery (Dhillon, 2007, p. 19).
Cybercrimes is rapidly growing and increasing at a substantial rate. This is a crime that affects everyone no matter where a person lives. Anything that connects to the internet is susceptible to attack. In fact Verizon quoted, “No locale, no industry or organization is bulletproof when it comes to compromise of data”. IBM President and CEO Ginni Rometty described cybercrime as, “The greatest threat to every profession, every industry, and every company in the world”. Individuals are just as susceptible to attack. There is a hacker attack every 39 seconds, affecting 1 in 3 Americans. In this essay I will cover types of cybercrimes and the affect they have on businesses, government agencies, and the economy.
