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
The main differences between the two are the speeds that they operate and the type of key that they use. Using a complex password with either encryption type will help protect against any brute force attacks. A hacker can compromise encrypted data by using multiple brute force attacks. Symmetric encryption is one the older and better techniques that is used to encrypt and decrypt all of the messages. This specific type of encryption uses a secret key that the sender and receiver must have.
The name pretty much sums up what these threats are. In this type of unsolicited attack, a series of regular pings often used for basic troubleshooting, are generated and sent out across groups of ip addresses. I t was noted that where a normal administrator would only ping one or two intended destinations, the internet criminal would be more ambitious and perform these sweeps, looking for as many network endpoints that they can be connected to (Conklin, White , Cothren, & Williams, 2004)). One key thing to note is that DNS lookups can also be the result of ping sweeps and port scans, using the same ping utility, but taking things a step further in the infiltration process. The IP addresses ware linked to endpoint names, which gives an attacker access to information as well to produce the end points names.
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?
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
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 Computer Fraud and Abuse Act explicitly states “when a trespass is made with an intent to defraud that results in both furthering the fraud and the attacker obtaining something of value” (Gallegos & Senft, 2009). This definitely applies in this case, the attacker(s) used an attack known as spear fishing to dupe our customers into unintentionally installing a keystroke logging virus on to their computers. Once the virus was in place the attacker(s) waited for our customers to log into their bank accounts and recorded all the information necessary to create new user accounts and transfer funds from our customers account to other various accounts eventually ending up in the attacker(s) accounts located overseas. This would meet the qualifications stated in the Computer Fraud and Abuse Act; the attacker trespassed on these computers with the intent to obtain something of value. Also by taking the data provided by the key logger they violated the Electronics Communications Privacy.
Some measures to help in information security could be aimed to data encryption, passwords, software, network security solutions and service companies offering voice encryption. Companies provide devices to the employees with a confidentiality policy on the use of such devices and the capability to store information. As competition grows confidentiality with company's data could create loss of confidentiality if data becomes compromised. Total security is not possible, only adoption of measures can prevent attacks on devices to protect information. The user is the greatest security treat, users lack common
In a law firm two people who normally have administrator access. A password is a form of protection against unauthorized use. You should probably not write down your passwords just in case someone gets a hold of it. There are also setting permissions that add to your security as well. Firewalls are good and help against websites that are illegitimate.
