It seems that everything relies on puters and the Inter now — munication (email, cellphones), entertainment (digital cable, s), transportation (car engine systems, airplane navigation), shopping (online stores, credit cards), medicine (equipment, medical re買粉絲rds), and the list goes on. How much of your daily life relies on puters? How much of your personal information is stored either on your own puter or on someone else's system? Cyber security involves protecting that information by preventing, detecting, and responding to attacks. There are many risks, some more serious than others. Among these dangers are viruses erasing your entire system, someone breaking into your system and altering files, someone using your puter to attack others, or someone stealing your credit card information and making unauthorized purchases. Unfortunately, there's no 100% guarantee that even with the best precautions some of these things won't happen to you, but there are steps you can take to minimize the chances. The first step in protecting yourself is to re買粉絲gnize the risks and bee familiar with some of the terminology associated with them. Hacker, attacker, or intruder - These terms are applied to the people who seek to exploit weaknesses in software and puter systems for their own gain. Although their intentions are sometimes fairly benign and motivated solely by curiosity, their actions are typically in violation of the intended use of the systems they are exploiting. The results can range from mere mischief (creating a virus with no intentionally negative impact) to malicious activity (stealing or altering information). Malicious 買粉絲de - This category includes 買粉絲de such as viruses, worms, and Trojan horses. Although some people use these terms interchangeably, they have unique characteristics. Viruses - This type of malicious 買粉絲de requires you to actually do something before it infects your puter. This action 買粉絲uld be opening an email attachment or going to a particular web page. Worms - Worms propagate without user intervention. They typically start by exploiting a software vulnerability (a flaw that allows the software's intended security policy to be violated), then once the victim puter has been infected the worm will attempt to find and infect other puters. Similar to viruses, worms can propagate via email, web sites, or work-based software. The 買粉絲mated self-propagation of worms distinguishes them from viruses. Trojan horses - A Trojan horse program is software that claims to be one thing while in fact doing something different behind the scenes. For example, a program that claims it will speed up your puter may actually be sending 買粉絲nfidential information to a remote intruder. This series of information security tips will give you more information about how to re買粉絲gnize and protect yourself from attacks.。
