Cyber terrorists can be motivated to target organizations that will result in the radical’s group to cause the most harm and/or receive the most attention for their party. Cyberterrorists use the internet to spread propaganda and enlist new members and use DoS/DDoS attacks to cause disruption to companies that represent actions against their belief’s (Vacca & Rudolph, 2011). Cyber terrorists can also steal information to be used for self-serving strategic purposes. Kostadinov (2012) makes the distinction between cybercrime and cyberterrorism in that the latter should resemble terrorist attacks via traditional methods but perpetrated virtually. Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting.
Networked Systems Security Task 1 – THREATS AND IMPACT OF NETWORK THREATS There are many types of threats that can damage your computer either temporarily or permanently. Some threats posed may not threaten your computer right away however have the potential to do so. Some threats that present themselves can include physical threats such as the theft of equipment whether that is the monitor, computer etc. Other threats can be harder to find such as viruses, worms or any kind of malware. Understanding these threats allows the organisation to prevent, protect and correct any damage done to his/her computer to an extent.
Port scan is as the name implies, a scan of the open ports on each computer of the network to define which ports are open and what services are running on them. This information can be used to set up an attack on the network by allowing the hacker to bypass vulnerability in the software being run or on any open ports that can be used to gain deeper access to the network. With a port scan the probe sends information to each port on the network and the open ones respond back, this data can be used to determine the easiest way to infiltrate the network. The safest way to defend against this type of probe is using a firewall. Just as in a ping sweep, if you deny access to a port scan requesting information from the network you render them
Unit 3 Assignment 1: Analyzing the Critical Security Control Points The following is a listing of security control points that any company should look at as necessary areas for precaution and care. Information covered by each area will be what each area consists of, how it strengthens the company security and what could happen if these areas are not properly maintained. 1. Inventory of Authorized and Unauthorized Devices and Software – a listing of processes and tools used to track/control/prevent/correct network access by devices and software. Attackers are always looking for devices and software that are newly added to a system and not updated correctly with the security measures in place already.
He can use the names or phone numbers listed in the DNS to gather more sensitive data. Internet Protocol Address range can also be of useful to the attacker. By knowing the IP range, the attacker can port scan and identify active machine on that network. Although IP address range finding is imposable to protect from hackers, there are still counter measures
Communication Proposal and Presentation Sabrina Hunter ENG/135 August 24, 2015 DR. Franklin Communication Proposal and Presentation Firewall System A firewall is a software that stands between your computer and the internet. Having a properly functioning firewall can stop potential threats affecting your computer, but it can also alert you when a problem is occurring as well. Having a firewall can save you and your business from having to spend extra money to get rid of a virus on your computer or becoming a victim by having your computer being a hack. By having a firewall, it stands between your computer and the internet it serves to block unauthorized request passing through your system. The firewall also serves as a packet filter.
I would implement firewalls, cryptography, antispyware, antivirus, and content filtering. These will be installed in various levels of our network infrastructure including, our mail servers, gateways, laptops and desktops. When these security technologies are in place a threat may be able to bypass on level of security but will be detected and eradicated at another. Layering our security in this manner will mitigate the risks of an employee disabling their protection on the workstations. Our mail servers which send, receive and store emails must be secured as well.
I can assume that my organization MIS department will do it for me because they would identify issues and problems and promote to employees how to protect their assets that might be vulnerable to theft in the outside world. It’s important to protecting our assets that might be on portable devices to prevent the theft, use two factor authentications, and encrypt your data. Protecting your privacy by using strong passwords, adjusting the privacy settings on your computer, and surf the web anonymously. Other ways to protecting your privacy may include e-mail anonymously by reporting spam to your email provider and knowing what information on your emal is creditable, and by erasing your Google search history to prevent important history from being discovered. | 2.
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.
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.
