2) What is a firewall and how does it work?

A firewall is a way of preventing unauthorized access from the internet. It does this by blocking the incoming and outgoing traffic on your computer. This means that it blocks traffic coming from outside the computer, as well as traffic going outwards. There are different types of firewalls, but they all do essentially the same thing: block unauthorized data exchange between networks. They accomplish this by using rules about which types of data can and cannot be exchanged with other computers on the network. The computer security fundamentals ebook may also filter content depending on who it’s being sent to or what type of content it is. The most common type of firewall is a software firewall, like the ones found in antivirus programs. Hardware firewalls exist too and are sometimes installed at the point where an ISP connects to your home (called a demarcation point). These have been replaced by some ISPs with proxies, which act like middlemen – forwarding requests for information back-and-forth between you and another computer while filtering content along the way.

3) What is an antivirus and how does it work?

An antivirus is a software that runs on your computer and scans for viruses. It works by checking the files on your computer against a database of known viruses, looking for any new threats or ones that are unrecognized. If it finds one, the software will quarantine or delete the virus file and alert you so you can take appropriate steps.

The antivirus program checks your computer’s programs and files against a constantly updated list of known malicious software (malware). If it recognizes an infection, it deletes or quarantines the malware. Other features include email protection, security updates, anti-spyware, anti-rootkit and even parental control tools.

One way to reduce risk when browsing the internet is by using a secure browser such as Chrome, Firefox or Safari instead of Internet Explorer. A secure browser encrypts data from your computer so it cannot be read if intercepted in transit over public Wi-Fi networks like those at coffee shops. Another solution is to install web browser plug-ins like AdBlock Plus and HTTPS Everywhere which block ads and other content that may contain malware respectively.

Most computers also come with a built in firewall as part of their operating system which helps protect them from incoming network traffic.

4) What are the most common types of malware?

There are many types of malware, but the most common types are ransomware, virus, Trojan horse and keylogger. Ransomware is a type of virus that locks your computer or encrypts your files and demands payment in order to grant you access again. A keylogger is a type of Trojan horse that records what you type on your computer and sends it back to the hacker. Virus can infect your computer by sending spam emails or opening attachments from unknown email addresses. They may also be able to install themselves onto your computer if you visit an infected website or download an infected file. Malware comes in many forms: some steal data such as passwords, bank account numbers, credit card numbers and login credentials; others are designed specifically for destruction such as deleting all of your hard drive’s data (known as wiping). Others still have more benign intentions but they do cause problems when they invade our computers.

5) How can I protect my computer from malware?

1. Install antivirus software, firewalls and updates. 2. Keep your operating system patched and updated. 3. Use a unique password for every service you use. 4. Use anti-malware software on all your devices (including computers, smartphones, tablets). 5. Don’t open attachments or click on suspicious links in emails that appear to be from someone you know (but might not be). 6. Check the sender’s email address before opening any attachments or clicking on links in emails that appear to be from someone you know (but might not be). 7.

6) How can I secure my Wi-Fi network?

1. Change your default wireless network name and password.

2. Select a wireless encryption standard, the stronger the better.

3. Turn off your wireless router when not in use or when you are away from home or work for extended periods of time.

4. Disable SSID broadcasting so that people cannot see your network by searching for it – they will need to know the name you gave it to find it on their own (and this protects against hackers).

5. Use an antivirus program, update patches, and keep your software up-to-date with patches (especially Internet browsers).

7) How can I keep my passwords safe?

1. Choose difficult passwords that are hard to guess and include a mix of letters, numbers, and symbols. 2. Do not share your password with others or write it down anywhere near your computer. 3. Change your passwords often so people cannot get access to them even if they happen to know the old one. 4. Use two-factor authentication when possible which will require a temporary code sent to you via text message or email before you can log in from an unrecognized device. 5. Get a high quality anti-virus software like Norton 360 (or other good options) installed on your computer and keep it updated with the latest virus definitions so they can catch threats as soon as they come out instead of waiting for them to infect you first! 6.
