When David tries to connect to his home Wi-Fi network, he finds that the router's default Wi-Fi password isn't working even though it worked earlier that day.He resets the device so all the default settings are restored.Two days later, the same problem happens again.What should he change so attackers can't keep reconfiguring his router?

Accepted Answer

David should change the access password to his router. This is the password used to log into the router's administrative interface, not the Wi-Fi password. If attackers have this access, they can change any settings, including the Wi-Fi password. Changing the access password will prevent unauthorized access to the router's settings.

Question 4

Martha has been appointed as the Data Security Manager of her organization.The company wants her to develop a customized app to remove viruses from the infected systems without connecting to the network.What type of app should she focus on developing?

A portable app is the best choice because it can be run on a USB stick or external hard drive without the need for installation or network connectivity. This means it can be used to remove viruses from infected systems without posing a risk to the company network. Mobile apps and productivity apps are not well-suited for virus removal, and web apps require network connectivity.

Question 6

When you access a secure website, what information does your browser use to verify that web server's identity and encryption information?

Accepted Answer

When accessing a secure website, the browser uses a digital certificate to verify the identity of the web server and its encryption information. The certificate is issued by a trusted third party called a Certificate Authority (CA), and serves as a digital "ID card" for the website. The password and encryption key are not used for verification, and a TIN is irrelevant in this context.

Question 9

Ricky's social media account was recently hacked.His bank accounts and email accounts use the same password as his social media account, and within a week, they were also hacked.What could Ricky have used to prevent the original attack from affecting so many accounts?

Accepted Answer

Ricky could have used a password manager to ensure that he was using unique and strong passwords for each of his accounts. This would have prevented the hackers from accessing his other accounts once they had hacked his social media account. Remote lockout and encryption do not directly address the issue of using the same password for multiple accounts. While a strong password is important, it may be difficult for Ricky to remember multiple strong passwords if he is not using a password manager.
