Browser security

Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript - sometimes with cross-site scripting (XSS) - sometimes with a secondary payload using Adobe Flash. Security exploits can also take advantage of vulnerabilities (security holes) that are commonly exploited in all browsers (including Mozilla Firefox,Google Chrome,Opera,Microsoft Internet Explorer, and Safari).

Security

Web browsers can be breached in one or more of the following ways:

Security

Security is the degree of resistance to, or protection from, harm. It applies to any vulnerable and valuable asset, such as a person, dwelling, community, item, nation, or organization.

As noted by the Institute for Security and Open Methodologies (ISECOM) in the OSSTMM 3, security provides "a form of protection where a separation is created between the assets and the threat." These separations are generically called "controls," and sometimes include changes to the asset or the threat.

Security has two dialogues. Negative dialogue is about danger, risk, threat and etc. Positive dialogue is about opportunities, Interests, profits and etc. Negative dialogue needs military equipment, armies, police. Positive dialogue needs social capital, Education, social interaction.

Perceived security compared to real security

Perception of security may be poorly mapped to measureable objective security. For example, the fear of earthquakes has been reported to be more common than the fear of slipping on the bathroom floor although the latter kills many more people than the former. Similarly, the perceived effectiveness of security measures is sometimes different from the actual security provided by those measures. The presence of security protections may even be taken for security itself. For example, two computer security programs could be interfering with each other and even cancelling each other's effect, while the owner believes s/he is getting double the protection.

Computer security

Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures.

The field is of growing importance due to the increasing reliance on computer systems in most societies. Computer systems now include a very wide variety of "smart" devices, including smartphones, televisions and tiny devices as part of the Internet of Things – and networks include not only the Internet and private data networks, but also Bluetooth, Wi-Fi and other wireless networks.

Vulnerabilities and attacks

A vulnerability is a system susceptibility or flaw, and many vulnerabilities are documented in the Common Vulnerabilities and Exposures (CVE) database and vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities as they are discovered. An exploitable vulnerability is one for which at least one working attack or "exploit" exists.

Olive Kitteridge (miniseries)

Olive Kitteridge is a 2014 four-hour miniseries based on the 2008 novel of the same name by Elizabeth Strout. Set in Maine, the HBO miniseries features Frances McDormand as the title character, Richard Jenkins as Olive's loving husband Henry Kitteridge, Zoe Kazan as Denise Thibodeau, and Bill Murray as Jack Kennison. The miniseries is divided into four parts, each depicting a certain point of time in the novel.

Olive Kitteridge debuted in the United States on November 2, 2014, on the American premium TV network HBO, which aired the show's first two episodes back-to-back that evening; the third and fourth episodes aired back-to-back the following evening. The miniseries was shown in a similar format in the United Kingdom on Sky Atlantic, on December 14 and December 15, 2014. It premiered in Australia on showcase from 13 January 2015. At the 67th Primetime Emmy Awards, the miniseries won eight awards including Outstanding Limited Series.

Premise

Olive Kitteridge is a misanthropic and strict, but well-meaning, retired schoolteacher who lives in the fictional seaside town of Crosby, Maine. She is married to Henry Kitteridge, a kind, considerate man who runs a pharmacy downtown, and has a troubled son named Christopher, who grows up to be a podiatrist. For 25 years, Olive has experienced problems of depression, bereavement, jealousy, and friction with family members and friends.

Browser

Browse, browser or browsing may refer to:

Web browser

A web browser (commonly referred to as a browser) is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content.Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

Although browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.

The major web browsers are Firefox, Internet Explorer/Microsoft Edge,Google Chrome, Opera, and Safari.

History

The first web browser was invented in 1990 by Sir Tim Berners-Lee. Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the Web's continued development, and is also the founder of the World Wide Web Foundation. His browser was called WorldWideWeb and later renamed Nexus.
