A data breach occurs when external entities penetrate an organization’s digital channels and access confidential information. The entity subsequently performs a series of destructive activities, including encrypting customer data, then demanding a ransom to restore access.

According to studies, about 60% of small businesses are forced to close their doors for good within six months after suffering a serious loss of data. Thus, it is crucial for those who lead companies to remain current regarding network threats and defense strategies. The two main sources of data breaches are summarized below.

Social Engineering Attacks

Programmed bots and cybercriminals can transmit spam to a company’s employees, typically by email. The messages attempt to persuade the staff to provide passwords and login names, click on links, open files, or download materials by pretending to be official security communications from a legitimate source. If successful, a point of direct access to the company’s network can be established.

Network Cyberattacks

Skilled hackers can find weaknesses in network defenses, like outdated operating systems, weak passwords, or ineffective antivirus solutions, allowing them to introduce viruses or steal data. In the aftermath of a serious cyberattack, organizations are often required to perform a system overhaul to ensure a secure network.

The above describes a general process for carrying out cyberattacks. However, several other causes can result in a major loss of data. These can include accidental or malicious damage to hard drives, natural and manmade disasters, and files mistakenly deleted by employees.

Part 2 will discuss the most typical types of cyberattacks.
