Biometric Authentication

Biometrics seem secure on the surface. As, you're single with ears, eyes and a unique fingerprint. However, it does not make it more secure than a password. A password is private by nature, because you are a special case who knows it. Of course, attackers can get it with brute force attacks or phishing, but in most cases they cannot get it easily, on the other hand biometrics are inherently public.

The identity management and security is a problem. Personal identifiable information (PII) needs to be controlled to protect against identity theft. All that is needed is for hackers to break each of these databases to collect biometric identification of users, which can affect privacy, and security of the victims.

Internet of Things (IoT) and Cloud Technology

Huge amount of information and data that IoT runs, surely be stored in the cloud almost certainly, cloud providers will be one of the standard targets in this kind of attack. While awareness of this problem is growing, cybersecurity is still not well funded, in contrast to the potential size of the threat. To get an overview of this problem, the report of the World Economic Forum refers to an investigation that proposes the elimination of a single provider in the cloud could cause financial damages of between 50 and 120 billion dollars this disaster somewhere close to the Hurricane Sandy and Hurricane Katrina.

Software Defined Networks (SDN)

Security in the Software Defined Networks (SDN) means more than system visibility and micro segmentation, such as John Burke, an expert in Nemertes Research. Organizations that want to stay on SDN security issues should address following three main problems:

  • Ensure the privacy of information.
  • Guarantee integrity of the system.
  • Guarantee the availability of network services.

When deploying Software Defined Network, the networking teams must know about the data protection and compliance requirements similar to those of the General Regulation of data protection. To do this, associations must know where the data is in the system and to what extent they remain there.

Wireless Network: Security

Organizations may have locked their Wi-Fi networks with the most dominant available security in the market, but what happens if they really lose a gadget that they used in a same network?

The device can be anything from a mobile phone, a computer, a tablet or even a computer. Whoever retrieves device may enter a situation where only the authorized person can enter, depending on the information you have stored about your device. Therefore, such kind of problems cannot be taken lightly at any costs.


Cryptography allows secure communication in the presence of third party, known as intruders. The encryption (remarkable cryptography segment) uses calculations and a key to change the information (ie, the normal text) to the encoded output (ie, the encrypted text). The specified calculation will reliably change the explicit text equivalent to the equivalent cipher text if a similar key is used. The algorithms are considered as safe if the attacker cannot decide on any plain text property or key, or given cipher text. Attackers should not be able to decide on a key that has been received in a hug amount of plaintext / encrypted combinations that used the key.
