TAILIEUCHUNG - Ten Ways to Improve the Security of a New Computer

A firewall is a device that controls the flow of information between your computer and the internet, similar to a router. Most modern operating systems include a software firewall. In addition to the operating system’s firewall, the majority of home routers have a firewall built in. Refer to your user’s guide for instructions on how to enable your firewall. Once your firewall is enabled, consult the user’s guide to learn how to configure the security settings and set a strong password to protect it against unwanted changes. . | Ten Ways to Improve the Security of a New Computer Jennifer Kent and Katie Steiner Why Should I Care About Computer Security Our computers help us stay connected to the modern world. We use them for banking and bill paying shopping connecting with our friends and family through email and social networking sites surfing the internet and so much more. We rely so heavily on our computers to provide these services that we sometimes overlook their security. Because our computers have such critical roles in our lives and we trust them with so much personal information it s important to improve their security so we can continue to rely on them and keep our information safe. Attackers can infect your computer with malicious software or malware in many different ways. They can take advantage of unsafe user practices and flaws in your computer s programs flaws including vulnerabilities and unsecured services and features and use social engineering in which an attacker convinces someone to perform an action such as opening a malicious email attachment or following a malicious link . Once your computer is infected intruders can use the malware to access your computer without your knowledge to perform unwanted actions. They can steal your personal information change computer configurations cause your computer to perform unreliably and install even more malware they can use to leverage attacks or spread malware to others. One of the most well-known attacks was the Conficker malware detected in late 2008. This malware grew to become one of the largest malware infections affecting millions of computers and causing billions of dollars in damage across the world. The Conficker malware had the ability to steal and relay personal information to attackers disable existing security measures like Windows Automatic Updates and antivirus software and block internet access to popular security websites. Attackers could use infected computers as part of a botnet or a collection of compromised
