 Now, the other things that are essential for internet security are the internet security products. Now, what are these? These are the antiviruses, the password managers and the security suits. So, an antivirus is basically to check if any file contains any malicious code that can harm your system and antiviruses get regular updates on what kind of codes that are available or known to cause certain malicious activities. So, updating your antivirus is one of the very important key points to have a secure system. So, these days, not just the antivirus, what we get are security suits. So, in security suits, you by default get certain firewalls which can do some stateful packet inspection that can check on what applications are communicating over the network and all of those things. So, it can also detect any malicious activities or any malicious communications that are happening through your system over the network. So, security suit is something which is much more advanced than just the antivirus. So, antivirus is only able to check certain files and softwares for the kind of behaviors that they perform, but a security suit can also check network activities that are happening over your system. Now, we have something called password managers. So, password managers are certain softwares that are heavily encrypted and can manage the number of a lot of passwords and these days you have a lot of applications, a lot of passwords that you use to access those applications and at times it becomes really difficult to remember all those different passwords and moreover, organizations have their own policies over having changing or having changed your password say in a fortnight or like in three months, six months. So, it becomes difficult to manage these passwords. Hence, some applications like password managers allow you to store those passwords. Now it's the time to come towards, come to a reflection spot. Now, what you can do is you can pause the video for some time and then try to answer the question. So, the question here is, which of the following is a valid example for a three-way multifactor authentication? Option A, password, a PIN code of SID, option B, password, face ID or a fingerprint, option C, password, secure token, PIN and option D, face ID, OTP and date of joining. Now you can pause the video for a while and try to see which one is the right option. Here, D is the correct answer as face ID is something you inherit, which is basically your face. OTP is received on your mobile phone, that is something you have and date of joining is something that you know. The others are using similar factors. Now, this brings us to the last topic that we want to discuss on insecurity which is basically certain practices that we can follow at home to ensure a secure communication and secure network.
