Basics of encryption technologies and their implementation

TRAINING DESCRIPTION

The “Basics of encryption technologies and their implementation” course is suitable for the technical staff of a company. The main goal is to become familiar with the basic understanding for the proper deployment of technologies utilizing cryptography. In the world of digital communications and the need for privacy, it is necessary to have available experts controlling interactions and context. By using incorrect method, security will be weakened – It allows for reading or modification of transmitted data and could reduce the speed. This would cause infrastructure investments to be squandered. It is necessary to realize that your data or your customers’ data are transmitted over a public space, so the only real protection is suitably selected cryptography. This course also provides appropriate training for engineers and the requirements imposed by law for cyber-security.

TRAINING DESCRIPTION

Wireless connectivity and communications are an integral part of communication. Wireless networks are becoming a challenge for hackers who use bugs and vulnerabilities to gain access to the wireless network infrastructure. Wireless Hacking helps IT professionals to test, develop and implement a secure network to understand the current security vulnerabilities and understand the planning and execution of attacks by hackers in their favor. This course will help participants understand how to improve the security of WLAN referencing attack methodology and also to understand the importance of penetration testing as a first defense. The course focuses on the description of the standard and its essential elements and in terms of safety, security vulnerabilities 802.11 description, methods of abuse and hardware and tools to be used in Windows and Linux environments. The fly in the post options are passed to the VPN option attack, attack option for the management of AP itself and the possibility of tunneling. Finally, the possibility of detection, recommendations and countermeasures are discussed.

Filtering – MAC filtering, its role and capabilities.

Attacks

Passive attacks – network monitoring, interception and analysis tools for data transfer

Attacks on authentication-attacks on encryption, DoS attacks, false wireless network
