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
Case Study 3 Andrew Kutanovski DeVry University Having a secure network is not an easy task to accomplish. You must cover every aspect that could possibly give an outsider the ability to gain unsecure access to the network. By having loopholes and backdoors, all of the vital information on the network is at risk of being stolen. To prevent this from happening, you must secure all incoming and outgoing information. This is called encryption; it’s the process of making an original message unreadable to unauthorized individuals.
b) It impacts your IT environment because without this things would get leaked and confidential information will be available to other countries. c) I don’t believe my organization complies with all of the requirements because I don’t work so this does not
The most cost effective way of preventing this type of invasion is the firewall, which will allow network administrators who have access to run diagnostic uses of the probes, while denying the same access to anyone outside of the network. If the probes are left unchecked without proper precautions on the network it would only be a matter of time before a breach would occur. This could cost the company everything in the long run. On a danger scale from 1 to 10 with 10 being the most dangerous, a ping sweep would run around a 3 and port scan would be around 5 or 6. I rate these probes like this as they are the detection methods used by hackers to enter a network; they are not the attack themselves.
They can choose to engage in deep thinking activities. Too much of anything is not good for any one, and this also applies to internet usage. Scholars say that the price of technology is alienation and that this indicates that the more distracted an individual becomes, the less able they are to experience human emotions such as empathy and compassion. It is still too early to tell what the results of the future effects of the internet, but as Carr states, “An intellectual technology exerts its influence by shifting the emphasis of our thought. As the brain adapts to the new medium, the most profound changes will take place over several generations’
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
With many network client devices, this results in the detected network displaying as an unnamed network and the user would need to manually enter the correct SSID to connect to the network. Unfortunately, turning off the broadcast of the SSID may lead to a false sense of security. The method discourages only casual wireless snooping, but does not stop a person trying to attack the network. It is not secure against determined crackers, because every time someone connects to the network, the SSID is transmitted in clear text even if the wireless connection is otherwise encrypted. An eavesdropper can passively sniff the wireless traffic on that network undetected and wait for someone to connect, revealing the SSID.
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
Firewalls are good and help against websites that are illegitimate. It’s also good to have an antivirus on your computer to help protect against people who are trying to hack into your system. Perhaps someone is trying to gain access to your financial information; the antivirus stops them from getting in. Always make sure that when you are checking your e-mail and receive an e-mail with an attachment if you do not know who it is from do not open it. I don’t even open e-mails from people I don’t know whether it has an attachment or not.
Because transactions take place over the internet companies have to ensure that the customer’s personal information is safe along with the company’s information. Companies use different types of security programs to keep information safe from computer attacks. Computer attacks on a company can happen when the security program is not effective enough to keep these attacks from happening or from the lack of monitoring of the security program from management. The task of monitoring the security program is given to management, so companies should be held liable for losses sustained in a successful attack made on its AIS by outside sources. In the following an explanation of management’s role and why a company should be held liable.
