If your system is infected, the virus may try to attach itself to every file in your system and spread each time you send a file or document to other users. Figure 9.3 shows a virus spreading from an infected system, either through a network or by removable media. When you give removable media to another user or put it into another system, you then infect that system with the virus. Figure 9.3 Virus spreading from an
destinations in routing tables. Routing tables contain information about known hosts on both sides of the router. B. Switches create virtual circuits between systems in a network. These virtual circuits are somewhat private and reduce network traffic when used. B. PPP can pass multiple protocols, and it is widely used today as a transport protocol for dial-up connections. A. PPP provides no security, and all activities are unsecure. PPP is primarily intended for dial-up connections, and it
lost its popularity, you might still encounter it in some texts. The most commonly implemented RAID levels are as follows: RAID Level 0 RAID 0 is disk striping. It uses multiple drives and maps them together as a single physical drive. This is done primarily for performance, not for fault tolerance. If any drive in a RAID 0 array fails, the entire logical drive becomes unusable. RAID Level 1 RAID 1 is disk mirroring. Disk mirroring provides 100 percent redundancy because everything is
your company data at heart. Figure 5.12 Examples of some questionable wireless networks Be sure to change the default password settings on all wireless devices. Never assume that a wireless connection is secure. The emissions from a wireless portal may be detectable through walls and for several city blocks from the portal. Interception is easy to accomplish, given that RF is the medium used for communication. Newer wireless devices offer data security, and you should use it. You can set
systems are updated. With VMware, patch releases are based on the code from the immediately preceding update, and compatibility for patches is assumed to have the same compatibility as the preceding update release. Although this approach differs for each vendor, most follow similar guidelines. Always verify the source of patches and test the patches on lab machines before applying them to production machines. It is possible for one patch not to be compatible with another, and you want to
