CYBER SECURITY INTRODUCTION TO PASSWORDS – STUDY MATERIAL, DECEMBER 2021
A password is a string of characters used to identify a user. It can be sometimes a word, number, name, animal name and so-on. We use passwords as a means of security to authenticate a user and avoid giving access to an unauthorized user. Password as a factor authentication method can be used in smart devices like phones, laptops, iPad and so-on, we also find passwords used in web applications as a means of logging into our online accounts like Facebook and Gmail. Passwords are either strong or weak. Weak passwords are short (i.e. 5-8 characters in length) and simple to guess. Name of a person, animal, a phone number, and even a pet’s name are examples of weak and guessable passwords. A strong password however is the opposite. Strong passwords are long in length (i.e. 10 – 16 characters), they have all character combination like numbers, letters, and symbols and are quite difficult to guess. People are known to create passwords based on their personal information because human beings are limited by their memory capabilities. We show that personal information plays an important role in a human-chosen password by dissecting passwords in a mid-sized password dataset.
Understanding the usage of personal information in passwords and its security implications can help us further enhance password security. Password Hacking Password hacking is a term used to describe the process of a hacker trying to obtain unauthorized access to a system belonging to an authorized user. Since passwords have been introduced to IT, cyber criminals have always found ways to get a hold of the passwords of other people in order to gain access into the devices and accounts of the victims. The following are ways in which passwords can be hacked, Password Attack: Use of computer software or tools Shoulder Surfing Social Engineering Inference Password Attacks: Password attacks involves the use of automated tools and computer software’s to crack passwords. Two of the most common ways automated tools work for password attacks is.
Shoulder surfing is defined as the process of spying on people while they use their smart devices like phone and laptop. It involves the attacker standing behind the victim looking over his/her shoulder to gather information like the password being typed. This is the simplest way to gather password information. Social Engineering: This is a situation where a hacker exploits the victim by socializing and establish a friendly relationship in order for the victim to reveal hidden information like his/her password, or phone number, and other sensitive information. Inference: This involves gathering an attacker trying to guess the password of the victim based on the information gathered about the victim through foot printing techniques. In order to prevent inference, users need to be educated on ways to secure their passwords. Another thing to do to prevent inference is to set your passwords in a way that as nothing to with other information like your street address, phone number, pet name, family name, name of workplace etc. Counter Measures to prevent password hacking:
