Attackers find deleted unencrypted copies of several files you created and stored as encrypted. 7. Another user makes destructive changes to one of your spreadsheets. 8. An attacker can access the Web server.
A worm is basically a virus that is network aware. It can move over the network and infect multiple computers in a matter of seconds. The Trojan program is based off of the Trojan horse story in Greek mythology, it appears to be a legitimate program, but usually hides a virus or worm. When the program is started, it will “drop” a virus or worm into the system and then the system will be infected. Spyware is almost exactly as it sounds, a spying program.
When an attacker conducts a ping sweep of a network, all active computers on the network will respond and provide the attacker with a list of IP addresses in the network. With this information the attacker can identify specific machines and eventually gain control of them and the information they can access. Ping sweeps can also cause a network to slow down. The network is flooded with requests, which leaves less room for regular traffic. Port scans are the way in for the attacker.
Infecting the boot sector and potentially controlling the operating system, attaching itself to a certain program, activating when you run your program and deactivation when the program is shutdown, loading itself into the memory, or waiting for a specific date and time. A Trojan horse is malicious and will hide itself within a trusted program, simulates a legitimate program causing damage to the computer or network during program execution. Two viruses that commanded the attention of the media were Melissa and ILOVEYOU viruses. Individually striking within fourteen months of each other and exposing the weaknesses in e-mail security and the lack of software to scan these files prior to opening. To be familiar with the person sending the e-mail was not acceptable anymore and it raised awareness
Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting. In order to prove that the network breach was a terrorist attack the company would need to provide electronic evidence of these types of information warfare. Information warfare is a term often used interchangeably with cyberterrorism but provides a deeper understanding in the shift of how data has become fundamental to society. As governments, companies and people shift to the use of digital information so have the methods used to attack (Gilmer, 2001). In order to combat this aspect of terrorism, the military have adopted computer forensics as part of their defenses (Vacca & Rudolph, 2011).
Having beep codes to help decipher the problem makes the repairs easier. The hard disk is busy when performing a cold boot because it is testing all of the hardware. With a cold boot, the BIOS verifies RAM by performing a read/write test of each memory address. It checks for a keyboard, mouse and for a (PCI) bus and, if it finds one, checks all the PCI cards. If the BIOS finds any errors during the POST, it will notify you by a series of beeps or a text message displayed on the screen.

By proper end user training for anyone involved with the Corporate Techs site, proper scanning of all USB and thumb drives on a test computer being used for this particular site, can mitigate threats from bugs and viruses. Also, by changing all local computer default autorun policies, will disable usage of these USB ports and stop an occurrence from taking place. Last, it’s almost near impossible for an end user to not use a personal laptop during work hours for personal use or for work. But to mitigate further problems from happening, I will implement an encrypted file system for sensitive data. TrueCrypt is a program that I have found efficient that controls over endpoints that enter and exit the internal system.
Because Kudler is expanding its stores, it is wise that Kudler Fine Foods begin to invest in an advanced system to protect its financial and employee records that are stored on the computers. Kudler Fine Foods will begin by adding a firewall to keep the threats from getting into the computer and wiping out the entire system. For added security install passwords on the computer that will allow only certain people to have access to the computer. Kudler will program each person to have their password for security purposes. Lastly, Kudler Fine Foods will also have additional software added to prevent malware.
They spread hate and use violence and threats to get their message across to those who go against what they believe or who they are against. They use the internet to spread their hate through websites and chatrooms and even offer online applications to get new members both home and abroad.
