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).
Match the attacks on the left with the vulnerabilities on the right that allows each attack to succeed. 1. An attacker is able to launch a denial of service (DoS) attack from a single computer that has attacked you before. 2. An intern can access several user accounts after learning their birthdays and pets names.
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
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. This is the door they look for to get in. A method to avoid such opportunities is to deploy an automated asset inventory discovery tool and use it to build a preliminary asset inventory of systems connected to an organization's public and private network. This will help make the system capable of identifying any new unauthorized devices that are connected to the network within 24 hours, and of alerting or sending e-mail notification to a list of enterprise administrative personnel. Without such a tool in place an attacker will use the unpatched device or software to gain access and manipulate the network how they please.
These three stores will need a cable or DSL set up so there internet is always on for better customer service, faster performance and faster response time or in another words a T1line which the speed will increase to 1.544 Mbps. Traffic analysis which is used for network detection and intrusions from outside sources, and is done by command lines tools which will provide information about the network latency. Nagios will be used to identify any
D) A denial of service attack occurs when the perpetrator e-mails the same message to everyone on one or more Usenet newsgroups LISTSERV lists. A) A denial of service attack occurs when the perpetrator sends hundreds of messages from randomly generated false addresses, overloading an Internet service provider's e-mail server. 8) Gaining control of someone else's computer to carry out illicit activities without the owner's knowledge is known as A) hacking. B) hijacking. C)
This helps with secure VPN and Internet traffic through the ASA 5510 VPN Router. The VPN is able to locate in a specific area where the malicious attack is coming from and which employee has done it. There is remote access to the Patton-Fuller network but it is secure and only personal that has been authorized accesses it.
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.
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.
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.
