Spyware is almost exactly as it sounds, a spying program. This type of malware will record the users input and transmit it back to the hacker to access at his leisure. This type of spyware is called a key logger and can capture interesting information such as user names, passwords, credit card numbers and email addresses. The more advanced versions of spyware can siphon off network data that will allow the hacker access to files, encryption keys, and other sensitive information. The final malware I will cover is the zombie.
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).
The risks that exist would come from a suspecting end-user, potentially some form of malware, that would be installed through an open port, thus causing the integrity of a machine on that network to be severely compromised (Lawrence, 2000). Ping sweeps and port scans are two direct unsuspecting threats that, like other cyber threats, are not to be ignored. The ease of gaining access by using these threat sources is something that a business should be aware of and be prepared to address when faced with being at the end of a cyber-attack. Implementing appropriate policy to counteract such a malicious and serendipitous attack on network vulnerabilities should be considered as an additional failsafe. Protection is the key and showing extra caution can at least reduce the
Malicious damage: Examples can be Viruses, Worms or Trojans a. Internal attacks come from within the organisation by disaffected staff. Individuals or a group have authorised access and privileges to the organisations network. They may use their knowledge on the organisations network to exploit or interrupt its functions. 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.
Which of the following account lockout policy modifications could you make to ensure that user passwords cannot be intercepted by analyzing captured packets? (D) Disable the Store Passwords Using Reversible Encryption policy 2. Which of the following mechanisms is most often used in firewall rules to allow traffic on to the network? (D) Port numbers 3. Which of the following NTFS features is incompatible with EFS encryption?
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.
Anyone whose personal computer is connected to a network or the Internet faces a potential risk of attack. Identify all the potential security threats on a personal computer. Identify some of the techniques an attacker might employ to access information on the system. SEC 280 Week
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
3. If the company is looking into using laptops and Internet access in the field, then it must consider encryptions. According to Pfleeger & Pfleeger, “encryption is powerful for providing privacy, authenticity, integrity, and limited access to data” (p. 444). I would suggest “end-to-end encryption” this is known to provide encryption from one end of transmission to the other” (p. 446). This way, information transmitted from the field would be in encrypted throughout the network.
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.
