Blue hat is a) hacker breaks security for altruistic or at least non-malicious reasons. b) hacker of ambiguous ethics and/or borderline legality, often frankly admitted. c) someone outside computer security consulting firms that are used to bug test a system prior to its launch, looking for exploits so they can be closed. d) None of these

Operating systems and the vast majority of other forms of software include bugs when they are originally released. Existing software contains tens of thousands of errors, sometimes known as bugs. By providing updates, software companies consistently address recognized issues with published software (also known as patches). The day after the public disclosure of a new vulnerability, hackers and other criminals often conduct zero-day attacks to exploit it. No one can disagree that these criminals' activities are immoral, but what obligation does a software company have if their ignorance or hurry to market harms customers? What responsibility do computer users have regarding the installation of security updates?
When operating systems and most other types of software are first released, they are not completely bug-free.There are applications available that contain tens of thousands of bugs.Known flaws in published software are routinely addressed by software companies through the distribution of patches (also known as patches).Hackers and other criminals frequently launch zero-day attacks the day after a new vulnerability is publicly disclosed. No one can deny that these criminals' actions are unethical, but what duty does a software company have if their negligence or haste to market causes harm to customers? What are computer users' responsibilities in terms of staying up to date on security patches?
Computer Security is one of the fastest-moving fields in the world today. There are generally several incidents each week, including data breaches, large scale attacks, or some advancement in security research (i.e. new tools, techniques, vulnerabilities, or exploits). Select a recent event from your favorite security news source and summarize it. Include your source and an analysis of the event, including a summary of what happened, any new information from the event that changes current security practice, and any larger scale implications from the event. Relate the event to the topics in Chapter 1 of the book, namely the CIA triad, U.S. Compliance Laws (if any), IT domains, security policy, and/or data classification. In addition, relate the event to a biblical example.
"System security" entails what exactly?
In Information security, a threat is a potential negative action or event facilitated by vulnerability that results in an unwanted impact to a computer system or application.a) Elaborate the different types of attacks on computer based systems.
A virus that infects an executable file on a computer. What changes should be made to the executable if any?
A downgrade attack
A computer virus is a little, deviously clever software that copies itself to other computers, causing those systems to act improperly. In general, the primary function of a virus is to replicate.
Defintion of "intrusion prevention system" is not provided.
A virus that infects a computer and attaches itself to a program that may be executed. If it is required to make changes to the executable, what kinds of changes should be made?
Review each scenario carefully and respond to each question as either (very ethical, ethical, neither ethical nor unethical, unethical, very unethical) and justify your choice. 3. A student found a loophole in the university computer’s security system that allowed him access to other students’ records. He told the system administrator about the loophole, but continued to access others’ records until the problem was corrected two weeks later. a.The student’s action in continuing to access others’ records for two weeks was:
Operating systems and the vast majority of programmes do not begin their lives devoid of bugs. Applications have tens of thousands of bugs in them at any one time. It is common practise for software suppliers to give fixes for recognised software defects (also known as patches). Criminals often launch zero-day attacks the day after a newly discovered vulnerability is disclosed to the public. Nobody can dispute the immorality of what these criminals are doing, but a software firm has what duty to its customers if their inexperience or haste to compete in the market causes them harm? Users of computers are required to install the latest security updates.
