One of the steps to protecting yourself from potential internet security threats is to stay informed about current internet security breach activities. Having knowledge about the various types of concerns will help ensure you are aware of symptoms that might indicate a particular problem as well as the consequences of various security breaches.
Viruses can replicate themselves and therefore they can spread from one file to another, as well as spreading from one computer to another. In many cases a virus is designed to damage or even erase data. On the other hand, worms replicate but they do not infect other files. Instead, these programs establish themselves on computers and create a single installation of their codes. Knowing this it is easy to deduct that the longer a virus is undetected the more files on the computer will become infected.
Trojans, or Trojan horses, usually appear to be legitimate software. The problem is, these programs will do harm to the computer. The difference between Trojans and viruses and worms is the fact that Trojans cannot spread by themselves. Trojan Spies, Trojan Proxies, Backdoor Trojans and password stealing Trojans are the most common types of Trojan horses.
A DoS, or Denial-of-Service, attack can obstruct or stop the usual function of a server or other network resource or a website. In some cases, hackers accomplish DoS attacks by sending the server more requests than it can handle. This causes the server to run slow and it will take web pages longer than usual to open. In the worst case scenarios the server may completely crash, which causes all websites on the server to go down.
Attacks that happen simply by visiting websites that contain a malicious code are called “drive-by downloads.” In these attacks, the cyber criminals have injected malicious codes onto web pages. Un-patched operations systems and applications make it possible for the spread of an infection to happen simply by accessing the infected web page.
Rootkits are used by hackers to gain unauthorized computer access without detection. These stealthy programs can be used to hide Trojans. Rootkits are essentially invisible and undetectable which makes them a tremendous internet security threat.
Malicious software is called malware. In reality the term malware can be used to refer to any program created to execute unauthorized and usually harmful actions. This includes Trojans, spyware, crimeware, viruses and adware.
Phishing is used by cybercriminals to scam internet users into revealing sensitive or personal information. This can include user names and passwords, social security numbers, credit card information and much more.
Programs that are designed to launch advertisements and/or forward search results to promotional websites are called adware. Many times adware is integrated into shareware and freeware programs. In most cases adware is essentially harmless, but sometimes a Trojan is incorporated into the program. In which case: much damage can result.
Spyware is a type of software that stealthily gathers computer data and sends it to a third party. Over time spyware will affect the performance of the computer. One type of spyware is a Keylogger program. Keylogger programs record key presses. This information can be used to obtain personal and sensitive information. Keyloggers are commonly integrated into Backdoor Trojans. Botnet is the term used to describe a network of computers under the control of a malicious program such as a Trojan.
Antivirus Software – the Key to Internet Security
An unprotected computer is an open invitation to cyber criminals of all types. With so many kinds of Internet security risks it just makes sense to use modern and up-to-date antivirus software. These programs are designed to prevent and remove various malware threats. Early antivirus programs were designed to check the boot sectors of floppy disks and hard disks as well as executable files. However, as new advances in internet technology continued so did the need for 먹튀 사이트 that are much better and advanced. Modern antivirus programs are automatically updated and can run checks in the background, even while the computer is in use. A quality antivirus software program can eliminate worries about internet security.
