Answer:
Option B i.e., False.
Explanation:
The weakness, KRACK tricks a wifi access points to reuse an in-use encryption, enabling the intruder to decode and interpret data intended to remain encrypted. Wireless communication encrypts, that decrypt unencrypted wireless network activity and expose sensitive data.
So, the following scenario is false about the wireless attack.
Answer:
require direct line-of-sight scanning.
Explanation:
Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.
Answer:
The operating system must by the use of policies define access to and the use of all computer resources.
Policies are usually defined during the design of the system. These are usually default in settings. Others are defined and or modified during installation of the addon and or third-party software.
Computer Security Policies are used to exact the nature and use of an organisations computers systems. IT Policies are divided into 5 classes namely:
- General Policies
- Server Policies
- VPN Policies
- Back-Up Policies
- Firewall Access and Configuration Policies
