CS406 Information Security

Answer 1:

VPN

VPN is Virtual Private Network By establishing a private network link over a public network connection, a virtual private network provides users with privacy, anonymity, and protection (Ferguson and Huston, 2016).

Pros

• Secures data: VPN encrypts traffic data so that no one can see access details.
• Online privacy: Once the traffic data is encrypted, online action will be private.
• IP change: Using VPN IP will be changed as traffic routes through remote server.
  
  

Cons

• Reduce internet speed: VPN will slow down the speed of internet as the routing and encryption works simultaneously.
• Insecurity: Sometimes some free VPN can collect the system data and sell to third parties as it can be insecure.
• Cost: A secure VPN can cost too much where it is not worth it for some time.

Answer 2:

In my opinion Linux is the most secure operating system. As the important thing is to execute a dangerous attachment it is difficult first of all the file needs to save in the system and need permission to execute in this process safeguard can kill that security breach. Linux does not give permission normal user to admin access (Lin et al., 2018). As the Linux is open-source big developers are working to fix vulnerability before hacker can catch it. These are the reason why Linux is more secure.

Answer 3:

A strong system access password can be defined as the passwords which are difficult to guess for human being or specialized software in short period of time. When a system access password is strong that means the length of the password is more, the password can contain mixture of upper and lower cases, password can have one or more numeric character, password can contain one or more special character so if a password contains these cases then the access password it strong and hard to guess as it cannot be cracked by any specialized software (Zviran and Haga, 2019).
