system administrator’s job duties are to test, patch and install the latest security updates and software fixes on an organization existing system. However, this task can become a race against time in trying to mitigate a security breach. Many times the system admin has to wait for the software vendor to produce a patch to fix the problem. This is most apparent when a company is infected with a Zero-Day Exploit. Zero-Day Exploit is an vulnerability cause by the software makers haste in bringing software
To: Incoming Computer Science Students From: Christopher Beberness Subject: Vulnerability Assessment Analysis Date: October 8, 2016 Purpose The vulnerability assessment is used in the cyber security field of the computer science. The purpose of this report template is to effectively convey information conducted from a penetration test on a company’s network. Background The vulnerability assessment report is comprised of any exploit or possible weaknesses found in a company’s network while conducting
Colored HATS IN NETWORK SECURITY In Computer security terminology Hacker is a person or group of persons, who exploit, modify and identify weakness in a computer system or network. Hacker may be motivates of reasons such as profit, protest and challenge. based on attitude, belief, and goals hacker groups are categories such as Black hat White hat Grey hat Blue hat Black hat: Black hat are the "hackers" which means they intentionally sent a malicious code into the computer system or network
Contrast and compare Hacking vs Penetration Testing. Hacking is a process in which one uses a computer or computer program to manipulate or exploit the weakness in a network system or a computer for the main purpose of causing harm, fear or make money. And a person who does this is called a hacker. Hacking was first made popular by the M.I.T engineers during late 1950’s and early 1960’s. Most of the hackings that are done by these engineers is out of curiosity but not with an intention to create
identifying weaknesses in computer security. Nowadays, numerous companies and governments use this technique to assess the level of security of their systems and determine if any valuable information is at risk of being accessed unlawfully. Ethical hackers are employed to identify potential threats on a single computer or a whole network of computers. The found potential exploits are later patched thus decreasing the chance of a breach in the system and increasing its overall security and reliability. In
Cao (2010) hypothesized that computer security is not as much about the aspect of technology, instead it is more concerned with the mental and social science activities of the individuals who utilize computer technology. The authors supported this point of view by stating that computers only channel the transgressions of the individuals who exploit them. Xu, Hu, & Zhang (2013) attributed the upsurge of hackers to the popularity of the internet and the prevalence computer systems. The authors maintained

What is Hacker? What is a hacker? This term has been used a lot lately, especially due to the cyber attacks that have escalated to a whole new level in the recent years. According to Sjoholm and Rosencrance, a hacker is “an individual who uses computer, networking or other skills to overcome a technical problem”. It also refers to a person that gains unauthorized access to systems or networks for the purpose of committing acts of malicious intent. There are three different types of hackers: White
delve deeper into the flaws and vulnerabilities and find their infallible remedies. My interaction with computers dates back to the days when I was very young and my father, a doctor in the army, was suddenly posted overseas in the Middle East, leaving behind his Desktop PC for me. Owning a Desktop in those days was a novelty in India and this independence had allowed me to tinker with the computer in every possible way. Operating systems like MS-DOS 6 and Windows 98 were then in vogue. Initially, I
Governments, security companies, and criminals are all potential buyers of zero day vulnerabilities. Security companies buy zero day vulnerabilities in order to gain a competitive edge. They use the zero days to provide their clients with protection from security risks that their competitors are unaware of. Governments often buy zero days to aid in their cyber warfare campaigns, or to protect their own systems from outside attack. Criminals buy zero days in order to exploit computer systems to accomplish
In computer security, a vulnerability is a weakness which allows an attacker to reduce a system 's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerability is also known as the attack surface. (Wikipedia). With this previous

What is Cyber Security? Cyber Security can be defined as “measures taken to protect a computer or computer system (as on the internet) against unauthorized access or attack”. (Bullock 283). In other words, an attempt by individuals to protect their personal information and other digital resources from attacks from the cyber world. Why is Cyber Security important? Chiefly, cyber security was created because of the sensitive information that is frequently stored on computers that are attached to the
between multiple computers. This occurred ten years after the first conceptual network architectural models which were initiated by Paul Baran and Donald Davies (History, 2014, p. 1, para 3). During the 1960’s and 1970’s ARPA was a primary source of funding for
hackers hack because they have ability to hack. The casual hobby for some hackers is hacking. They test their own system just to test and see what they can hack and what they cannot hack. The guys who get kicked out of corporate and government IT and security organizations are mostly the hackers. By attacking and stealing information, they try to bring down the status of the organization. The addiction for hackers is the knowledge they gain after the malicious hacking and the ego comes along with that
personnel that are often employed to find holes, penetrate or exploit a security system so the company can take corrective actions. Black hats are typically associated will malicious activity (cracking) such as developing and deploying viruses, worms, theft or damaging a system. The gray hats are somewhere in between the white and the gray hats. Arnone discusses how the federal government is utilizing hackers to test their own security measures and learn how to secure their systems by understanding
Ethics of Full Disclosure of Security Holes Introduction Security breaches are making big headlines nowadays, and Microsoft is leading the charge. Its flagship operating systems and office suite are so bulky and complex, that it is impossible to be bug-free. The system administrators (the white hats) are up to their noses plugging all the holes from super hackers (the black hats). Yet they are also facing attack from another front – those that post vulnerabilities on the internet (the

In the modern context, security lapses could cost organizations lots of money, valuable data, and crippled operations. It is critical for them to understand probable security

The majority of professional hackers are referred to as “white hat” hackers. The term white hat comes from old movies when the good guy would wear a white hat, and the bad guy would wear a black hat. The first real hack happened before there were big security systems, and even before cell phones. Phreaking
never be overlooked is security and personal safety. Especially considering everything has become digital in the recent years. Everyone’s personal information is being stored in facilities that we don’t even know where they are. With that being said there are people out there who target on the ignorant and misinformed. One way to protect yourself and your business from any threat is to be informed with the recent news on security. Here are some examples • Take Security seriously • Creating Strong
