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).
Internal attacks can be more difficult to find as attackers have the potential to remove any evidence of the attack more easily as they have more knowledge or access rights on the system as opposed to an outside attack. Attacks can be administrated via removable devices such as a USB that could contain some form of malware on it such as a virus. Most internal attacks are conducted by unhappy employees who want to disrupt the organisation by using the knowledge they obtained in the organisation, against the organisation. Additionally, the employee may want to gain access to important data in order to infiltrate and sell the information onto another competing organisation. The
If your computer has damaged because of the virus, you may have to purchase a new computer. By installing the firewall and an antivirus protection for your systems you are protecting one of your valuable
Viruses and Worms Operating system security is at the core of a safe, secure operating system. Our computers are vulnerable to corrupt files, compromised data, and system crashes. There are many attack methods used to uncover your personal information. Two of the methods are viruses and worms. A virus is an executable code usually sent in an e-mail attachment or hidden in audio clip, video clip, or game.
Two basic approaches are used in deliberate attacks on computer systems: data tampering and programming attack. Data tampering is a common means of attack that refers to an attack when someone enters false, fabricated or fraudulent data into a computer or changes or deletes existing data. This is the method often used by insiders and fraudsters and is extremely serious because it may not be detected. Programming attacks are popular with computer criminals that use programming techniques to modify other computer programs. For these types of crimes, programming skill and knowledge of the targeted systems are needed.
Since confidentiality is an issue, smartphone transmissions signals can be hacked by accidental broadcast. Third party snooping, can hack blue tooth signals that transmit confidential information. Stolen phones create a threat to business and the community through fraud. Training employees can be a measure to minimize the risks that poses a threat to cell phones. Some measures to help in information security could be aimed to data encryption, passwords, software, network security solutions and service companies offering voice encryption.
If your PC was shipped with a bunch of stuff you’ll never use, get rid of that software. Generally, you can go to Start | Control Panel | Programs and Features and remove software you no longer plan to use. If the software adds items to the startup process, getting rid of it will make the PC start faster and, ultimately, perform better overall. 4. Keep viruses and spyware off your system If you’re running Windows, you need to be running an anti-malware program to keep viruses and spyware off your system.
Unit 9 Assignment 1: List Phases of a Computer Attack In this assignment I am a hacker who needs to protect my organization from a computer attack. I will list general phases of a computer attack. We have an organization that we need to protect from outside attacks by foreign parties. I am an ethical hackers who needs to take preventative measures in order to adequately secure the network against these attacks. Many attackers follow a general set of steps in order to gain the permissions necessary to break into a system.
Simple viruses are dangerous; it uses available memory and can bring down an entire system, there are viruses that can bypass security systems and networks. To protect your computer system from this type of malicious code, you can install and use an antivirus program. This utility scans hard disk drives for viruses, worms and Trojan horses and removes, fixes or isolates any threats that are found. Most antivirus programs include an auto-update feature that enables the program to download profiles of new viruses so that it can check for the new viruses on your system as soon as they are discovered. However, there is another kind of software that can be used to protect your computer and personal information, which is spyware this is software that gathers user information without his or her knowledge, for advertising purpose.
The ping sweeps and port scans are the two techniques that malicious computer users such as hackers that can use to compromise an Enterprise networks security and gain access to their proprietary data. The ping sweeps are performed to find an open-door into a particular end-point. A person usually can find all kinds of utilities on the internet to exploit the open-doors on the system and gain access to important and confidential files on the network. It is a good idea that we try to protect ourselves against all these types of activities on the network and to also try to conduct them ourselves that way we know that out networks are safe. The ping sweeps are what you really think they are.
