Environments SCADA (supervisory control and data acquisition) refers to equipment often used to manage automated factory equipment, dams, power generators, and similar equipment. The Security+ exam does not heavily emphasize this, because the security measures will depend on the device. However, the infamous Stuxnet virus targeted specific SCADA equipment, so the need for SCADA security is not simply hypothetical. Embedded systems (such as printers, smart TVs, and HVAC controls) have their own security needs. Most modern printers, even midrange printers, have hard drives, RAM, and an operating system. That means…
Wireless networking, more commonly termed as Wi-Fi, is the technology that opens your PDA or laptop computer to the world. However this technology is quite vulnerable to many exploits. A malicious intruder can use the most basic software to detect and capture the signal of your wireless device, along with usernames, passwords, emails and other data you would prefer to keep confidential. An intruder doesn’t have to be inside of your home or office building to manipulate a wireless signal. For example, they could be sitting outside in their car…
Confidentiality One of the major reasons to implement a cryptographic system is to ensure the confidentiality of the information being used. Confidentiality may be intended to prevent the unauthorized dis- closure of information in a local network or to prevent the unauthorized disclosure of information across a network. A cryptographic system must do this effectively in order to be of value. The need to keep records secure from internal disclosure may be just as great as the need to keep records secure from outside attacks. The effectiveness of a cryptographic…

IPSec Internet Protocol security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IPsec supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. The Microsoft implementation of IPsec is based on Internet Engineering Task Force (IETF) standards. In Windows 7, Windows Server 2008 R2, Windows Vista and Windows Server 2008, you can configure IPsec behavior by using the Windows Firewall with Advanced Security snapin. In earlier versions of Windows, IPsec was a stand-alone technology separate from Windows Firewall. One of…
