Data is the main drive but not the only reason for a security breach

A security breach or security violation occurs when an individual or an application gets unauthorized access to a confidential or private logical information technology (IT) perimeter. In most cases, security breaches are done to steal data, which is known as a data breach. Data taken may include social security numbers, addresses, credit card information, names amongst others. For example, data breach at Equifax in May 2017, the involved hackers aimed at accessing data such as driver’s license numbers, dates of birth, addresses, names, and social security numbers. Same to Facebook security breach back in September 2018, when cybercriminals identified some security flaws, broke into user accounts including that of the CEO and the chief operating officer and then stole personal information for more than 29 million Facebook users. But this is not the case always!

Then, what are the other reasons for a security breach? 

A security breach or security violation occurs when an individual or an application gets unauthorized access to a confidential or private logical information technology (IT) perimeter.

1. Denial of Service

This is a security breach that overwhelms a system’s resources so that it either responds inappropriately or in some cases, to deny complete access to service requests. For some cybercriminals, they find satisfaction in denying other people services. For instance, during registration for some application done online, a security breach may be launched to jam the network so that only a few people manage to apply. 

2. Taking a System Down to Launch Another Attack

This is also referred to as session hijacking by most computer experts. An attacker intentionally and illegally hijacks an ongoing session between a trusted client and a network server. 

A client initially connects to the server, then the attacker’s computers gain control and then disconnects the client from the server. After which, the cybercriminal replaces clients IP address with their own. This is done to maintain the same identity so that they take over the conversation with the server. The attacker can then proceed to launch the intended attack from their henceforth as they now have complete access. In some cases, attackers block the server such that they are the only ones who can now access them. 

3. To Steal Cash

An attacker convinces a system through IP spoofing that it is communicating with a trusted entity, a known client, and to provide the attacker with full access to the system. The attacker then electronically wires or set rates at which cash will be continuously wired into their accounts. 

4. Influencing Others into Taking Actions that they do not Intend to do

A security breach may be done through a combination of technical trickery and a bit of social engineering. It can be through emails with misleading information but seems to come from a trusted client.

5. Eavesdropping

Eavesdropping or spying is done through the interception of network traffic. The hacker may do this to track property or an asset. In passive eavesdropping, a hacker spy on a system by directly listening to the message in the transmission network. 

Conclusion

To mount a good defense, it requires a deeper understanding of the offense. Most hackers try tirelessly to break protected IT perimeters to not only still data but to do all the above mention activities. Reasons for security breach are various, and so are the measures to counter each logic. Be alert!
