The Cybersec Bot

Hello all!! Do you also have a smartphone with fingerprint sensor and a face recognition sensor or camera? Nowadays even ₹5000 smartphones come with Fingerprint sensors. We all know Biometric authentication is superfast than password or pin or even dot pattern for that matter. It looks secure enough, but is it really? Let's start by understanding how biometric authentication works. These sensors capture your fingerprint and store it as a mathematical complex equation or as an image, same goes for facial recognition too. Now everytime you touch a fingerprint sensor it captures the fingerprint and matches it with the original math equation or an image, if there is a match then the system grants access. If it doesn't match then it doesn't grant you the access, it's simple as that. We think that fingerprint authentication is more secure than the password authentication, because fingerprints is unique. But as of now fingerprints are not more secure than passwords, infact fin...

Hey all!! We have so many online accounts these days and it's hard to remember all the passwords. So let’s talk about password managers and should you use them. Passwords with 8 characters or less are not so secure these days. Anyone with a decent laptop or PC, can use cracking tools and password dictionaries to crack passwords. Passwords with 8 characters or less take only 30 seconds to 1 minute to crack depending upon the processing power of the machine. So if your passwords are of 8 characters or less, consider changing them and read my ”Which word?...Password” article to get some information about strong passwords and how to create them. Ok, now moving on our actual topic “Password Managers”. If you have 10 or less online accounts, I would suggest remembering the passwords instead of using a password manager. Here is one tip for remembering the passwords; choose a long sentence with some special characters and numbers. Ok let's use the same password, we create...

Namaste!! Today’s topic is Two Factor Authentication. It’s also known as 2FA. We all know that multi-layered security is more secure than single layer security. As processors get faster, password cracking becomes easier and faster. So we need a Multi layer security system to secure our accounts. If your password gets cracked, 2FA is the new line of defence which restricts the access to your account. Many websites have an option to enable two factor authentication. This new account security technique needs two things to authenticate the owner. Something that only you know (password) Something that only you have (some kind of code) You know the password of your account. But now you need “something that you have” to get access to your account, that’s where 2FA kicks in. You can use any method mentioned below to act as second factor of authentication Authentication app SMS (OTP) Email (OTP) Preshared codes Security key (A physical device that looks like a pen-drive) Let’s ...

Hi!! So, in the previous article, you read the importance of cyber security. Now let’s see how to apply the security and secure your online and other digital accounts. When you create any online account like Gmail, Facebook, Snapchat or even an online net banking account of your bank, you are asked to set a pin or password. Now I know that you can't proceed without doing so, but many people take these passwords lightly and often set a weak password like the word “password” itself. Even though the website accepts that password, in some cases you are required to meet the password policy requirements. These password policies such as password must be 8 characters or more and it must contain special character like $,#,@ etc. So these password policies are there to make sure that you don't set weak and simple passwords. Many websites show strength meters while creating passwords. Please pay attention to the strength of your password. Now let’s see how to set a strong yet e...

Hey guys!! My name is Aditya Natu. I am 20 years old. I am an upcoming cyber security enthusiast. I am currently pursuing Cisco Certifications and some cyber security certifications. I hope you'll find this blog useful. So let's get started. Well, the era of cyber is here since we started using the internet. We almost do everything using the internet. For eg: You want pizza? Order it using the internet. You want to watch movies and TV shows? Use the internet. From net banking to online real time multiplayer games like PUBG and CS:GO, every little thing uses the internet in some form or another. Without the internet we can't live and survive in this modern world. The servers, important documents, many research findings, millions of pages of information, various systems like electric grid, government schemes and services, traffic signal systems, international trade and information exchange, etc depends on the internet. Here is a fact for you: the “Internet” is jus...
