Latest Data Breach News Story

By Alisa Fetic


The breach of Optus' customer database is the latest data breach story to rock the news. The data breach exposed the personal information of hundreds of thousands of customers, including their names, dates of birth, and phone numbers.


As a result, Optus began notifying customers who may have been affected by the breach. On their website, they posted a statement stating that it is collaborating with the Australian Cyber Security Center to reduce any threats to customers.


Optus also reported the "strange activities" to the Australian Federal Police, and an investigation was launched to determine who has been accessing the data and for what reason.

The company assured its customers that it would provide updates as they become available. They also advised them not to use passports for online identification until the matter is resolved.


Optus also notified its customers to be alert for any fraudulent activity they detected. Furthermore, they should secure their online accounts using two-factor authentication and unique, complicated passwords.

But how could this data breach have been prevented?


How Optus Could Prevent Data Security Breaches


Redaction


Redaction is a way to hide sensitive information from the public view. It is commonly used in the legal and financial industries to protect confidential information that criminals or competitors may use.

Redaction is also used to release information about a client, such as names and addresses, to prevent cyber criminals from learning more about them.


The process can be done manually by hand-writing over the original document or electronically by using computer software like Objective Redact or CaseGuard.


More Ways Optus Could Prevent Data Security Breaches


Install Firewall Software


A firewall protects from hackers by blocking unauthorized attempts to access or modify network data or control systems. It also prevents intruders from using your computer as an entry point into the network or accessing sensitive files on it.


There are two types of firewall software: hardware-based and software-based. Hardware-based firewalls include routers and switches that protect the entire network by restricting all traffic passing through it. Software-based firewalls run on a single computer and can be set up at home or in business premises to separate work and private networks.


Encrypt All Customer Data


Encryption is a process that transforms plain text into cipher text. This transformation prevents someone from viewing or accessing your data without the proper key needed to decrypt it.


In this way, if a hacker were to break into your system and steal passwords, they would not be able to access any other information in the system because all their passwords would be encrypted with that one key.


Encrypting client information helps prevent hackers from gaining access to them while being transmitted between servers and users in a network.


Limit Employee Access to Crucial Company Data


To do this, businesses can implement policies limiting how much access each employee has to critical company data. These policies may include:


A password policy: Allowing employees to log in with a password rather than using their name and social security number (or other personally identifiable information) as their username will help ensure that no unauthorized person can access your system.


Wrap-Up On Optus's Data Breach


Data breaches can have a devastating effect on affected companies, not to mention their customers. In reality, they are one of the biggest threats to the corporate world, yet many companies lack a sufficient defense against them. All it takes is one mistake to let a hacker in, and they can wreak havoc on your data. Companies should take caution by using measures like redaction to ensure their client's data is safe.
