In a contemporary technological world where we are witnessing innovations and developments in almost every sphere of life we must not forget or underestimate those who can employ modern tactics to get ahold of precious information and data present online to use it for malicious purposes.
We decided to discuss the most important and common challenges or threats every one of us can face either due to the carelessness on our side or over-smartness on the other side.
Data Tempering to Make It Malicious before Reaching the Destination
Confidentiality in terms of communication is very important to make sure that any data content would stay secret upon transmission. However, there is a possibility that a malicious third party can pull off the data while sending it. How does it work? Itinterferethe normal flow of data by finding a way to get into it and alter it with malicious contents before it gets to its destination.
Using Packet Sniffer to Spy On Private Data
Sensitive data like credit card numbers should be stored and transferred with protection. The internet which isapublic data carrier and Wide Area Network (WAN) a private network uses landlines, microwaves, satellite links and sometimes servers to send their private information and sensitive data. However, during the process the interested parties are able to see the data because it is open to them. For instance, Local Area Network (LAN) which is commonly used in schools, businesses and organizations can view sensitive data which are not meant for them. It is easy to install network sniffers and packet sniffers to spy on private data of users and steal their passwords and usernames.
Stealing Identities Online and Using for Frauds and Scams
Knowing who your users are is very important. A user can easily get into someone’s identities to steal his private info and accounts in a distributed online environment. Stealing identities online has been a threat to an online environment ever since. Primarily, hackers would steal other people’s identities to be able to access their bank details and credit card numbers to make purchases. Furthermore, they can also steal driver’s license numbers, credit and account numbers.
Another big threat online is non-repudiation which is a way of getting user’s digital signature. How can you protect your digital signature? When someone steals another user’s digital signature he would be held responsible for his actions.
Accessing Passwords to Get Control over Personal/Business Accounts
When using a huge system online, a user is required to keep multiple passwords for various applications and services they use. However, users tend to use several easy ways in managing their passwords:
1. Using simple and easy-to-guess passwords like name, characters in books or movies as well as words you can easily guess in your dictionary. However, these kinds of passwords are easy to access through the use of dictionary.
2. Creating and using similar passwords in different sites and services. Hence, as a result they become an easy prey of hackers who want to steal passwords. Using general passwords which are derived from common passwords are very dangerous.
3. Putting a password-reminder in the most common places where hackers can easily access them. At the same time, you forgot where you place the passwords. Thus, you end up paying for a huge amount of customer support to recover your passwords and your account. This thing can trigger hackers to get into your account and steal your sensitive data more. At the same time, creating different accounts and passwords would consume a lot of your time and money, plus multiple accounts are difficult to handle.
So if you have never thought about these security risks and challenges present in our online environment then think over it and take necessary measures to mitigate them timely and effectively.
