When a computer connects to a network and begins communicating with other computers, it is essentially taking a risk. Internet security involves the protection of a computer's Internet The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and account and files from intrusion of an unknown user.[1] Basic security measures involve protection by well selected passwords A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource . The password should be kept secret from those not allowed access, change of file permissions and back up of computer's data.
Security concerns are in some ways peripheral to normal business working, but serve to highlight just how important it is that business users feel confident when using IT systems. Security will probably always be high on the IT agenda simply because cyber criminals know that a successful attack can be very profitable. This means they will always strive to find new ways to circumvent IT security, and users will consequently need to be continually vigilant. Whenever decisions need to be made about how to enhance a system, security will need to be held uppermost among its requirements.
Internet security professionals should be fluent in the four major aspects:
- Penetration testing
- Intrusion Detection In Information Security, intrusion detection is the act of detecting actions that attempt to compromise the confidentiality, integrity or availability of a resource. When Intrusion detection takes a preventive measure without direct human intervention, then it becomes an Intrusion-prevention system
- Incidence Response
- Legal / Audit Compliance In general, compliance means conforming to a rule, such as a specification, policy, standard or law. Regulatory compliance describes the goal that corporations or public agencies aspire to in their efforts to ensure that personnel are aware of and take steps to comply with relevant laws and regulations

Anti-virus
For more details on this topic, see Malware Malware, short for malicious software, is software designed to infiltrate a computer system without the owner's informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. The term "computer virus" is sometimes used as a catch-.Some apparently useful programs also contain features with hidden malicious intent. Such programs are known as Malware Malware, short for malicious software, is software designed to infiltrate a computer system without the owner's informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. The term "computer virus" is sometimes used as a catch-, Viruses A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and archaea. Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898, about 5,, Trojans A Trojan, sometimes referred to as a Trojan horse, is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user's computer system. The term is derived from the Trojan Horse story in Greek mythology, Worms A computer worm is a self-replicating malware computer program. It uses a computer network to send copies of itself to other nodes and it may do so without any user intervention. This is due to security shortcomings on the target computer. Unlike a virus, it does not need to attach itself to an existing program. Worms almost always cause at least, Spyware Spyware is a type of malware that is installed on computers and collects little bits of information at a time about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. Sometimes, however, spywares such as and Bots.
- Malware is the most general name for any malicious software designed for example to infiltrate, spy on or damage a computer or other programmable device or system of sufficient complexity, such as a home or office computer system, network, mobile phone, PDA, automated device or robot.
- Viruses are programs which are able to replicate their structure or effect by integrating themselves or references to themselves, etc into existing files or structures on a penetrated computer. They usually also have a malicious or humorous payload designed to threaten or modify the actions or data of the host device or system without consent. For example by deleting, corrupting or otherwise hiding information from its owner.
- Trojans (Trojan Horses A Trojan, sometimes referred to as a Trojan horse, is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user's computer system. The term is derived from the Trojan Horse story in Greek mythology) are programs which may pretend to do one thing, but in reality steal information, alter it or cause other problems on a such as a computer or programmable device / system.
- Spyware includes programs that surreptitiously monitor keystrokes, or other activity on a computer system and report that information to others without consent.
- Worms are programs which are able to replicate themselves over a (possibly extensive) computer network, and also perform malicious acts that may ultimately affect a whole society / economy.
- Bots are programs that take over and use the resources of a computer system over a network without consent, and communicate those results to others who may control the Bots.
The above concepts overlap and they can obviously be combined. The terminology, along with the dangers involved, are constantly evolving.
Antivirus Antivirus software is used to prevent, detect, and remove malware, including computer viruses, worms, and trojan horses. Such programs may also prevent and remove adware, spyware, and other forms of malware programs and Internet security programs are useful in protecting a computer or programmable device / system from malware.
Such programs are used to detect and usually eliminate viruses. Anti-virus software Antivirus software is used to prevent, detect, and remove malware, including computer viruses, worms, and trojan horses. Such programs may also prevent and remove adware, spyware, and other forms of malware can be purchased or downloaded via the Internet. Care should be taken in selecting anti-virus software, as some programs are not as effective as others in finding and eliminating viruses or malware. Also, when downloading anti-virus software from the Internet, one should be cautious as some websites say they are providing protection from viruses with their software, but are really trying to install malware on your computer by disguising it as something else.
Anti-spyware
For more details on this topic, see Malware Malware, short for malicious software, is software designed to infiltrate a computer system without the owner's informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. The term "computer virus" is sometimes used as a catch-.There are two major kinds of threats in relation to spyware:
Spyware Spyware is a type of malware that is installed on computers and collects little bits of information at a time about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. Sometimes, however, spywares such as collects and relays data from the compromised computer to a third-party.
Adware Adware, or advertising-supported software, is any software package which automatically plays, displays, or downloads advertisements to a computer after the software is installed on it or while the application is being used. Some types of adware are also spyware[citation needed] and can be classified as privacy-invasive software automatically plays, displays, or downloads advertisements. Some types of adware are also spyware and can be classified as privacy-invasive software. Adware often are integrated with other software.
Email Security
A significant part of the Internet, E-mail encryption E-mail encryption refers to encryption, and often authentication, of e-mail messages. E-mail encryption can rely on public-key cryptography is an important subset of this topic.
Browser choice
Almost 70% of the browser market is occupied by Internet Explorer Windows Internet Explorer , is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems starting in 1995. It has been the most widely used web browser since 1999, attaining a peak of about 95% usage share during 2002 and 2003 with IE5 and IE6 [1]. As a result, malware writers often exploit Internet Explorer. Often malware exploit ActiveX ActiveX is a framework for defining reusable software components in a programming language independent way. Software applications can then be composed from one or more of these components in order to provide their functionality vulnerabilities. Internet Explorer market share is continuously dropping (as of 2009; see list of web browsers This is a table of personal computer web browsers by year of release of major version, in chronological order, with the approximate number of worldwide Internet users in millions. Note that Internet user data is related to the entire market, not the versions released in that year. The increased growth of the Internet in the 1990s and 2000s means for statistics) as users switch to other browsers, most notably Safari (web browser) Safari is a graphical web browser developed by Apple and included as part of the Mac OS X operating system. First released as a public beta on January 7, 2003 on the company's Mac OS X operating system, it became Apple's default browser beginning with Mac OS X v10.3 "Panther." Safari is also the native browser for the iPhone OS. A, Firefox Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. As of June 2010[update], Firefox was the second most widely used browser, with 23.81% of worldwide usage share of web browsers, according to Net Applications. Other sources put Firefox's usage share between 20% and, Opera Opera is a web browser and Internet suite developed by Opera Software. The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC, downloading files via BitTorrent, and reading Web feeds. Opera is offered free of charge for personal computers and mobile and Google Chrome Google Chrome is a web browser developed by Google that uses the WebKit layout engine and application framework. It was first released as a beta version for Microsoft Windows on 2 September 2008, and the public stable release was on 11 December 2008. The name is derived from the graphical user interface frame, or "chrome", of web.
Buffer overflow attacks
For more details on this topic, see Buffer overflow In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory. This may result in erratic program behavior, including memory access errors, incorrect results, program termination , or a breach of system.A buffer overflow is an attack that could be used by a cracker to get full system access through various methods. It is similar to "Brute Forcing" a computer in that it sends an immense attack to the victim computer until it cracks. Most Internet security solutions today lack sufficient protection against these types of attacks.
