They break into computer systems, frequently with intentions to alter or modify existing settings. Sometimes nasty in nature, hacking may cause damage or disruption to computer systems or networks. "Unauthorized access" involves approaching, trespassing , communicating with, storing data in, retrieving data from, or otherwise intercepting and changing computer resources without consent. The goals created by these people are negative and range from accessing and downloading data from corporate servers to defacing a public website. Hactivism is strictly confined to negatively-orientated goals due to the legal and right implications’ that come of controlling private information.
A virus can only spread when it is transmitted by a user over a network or the Internet, or through removable media such as CDs or memory sticks. Viruses are sometimes confused with worms and Trojan horses, or used incorrectly to refer to malware.” With a virus to a pertaining to a personal computer it can delete files and cause damage to your personal computer and causes damage to the hard disk and other aspects of your personal computer. The next threat that people should watch out for is Spam/Spim/Spit. They all are dealing something online pertaining to email, instant messaging or VoIP. This can slow down your network and run the risk of sending faulty email.
The security weaknesses also make it possible to send malicious commands to the devices in order to crash or halt them, and to interfere with specific critical processes controlled by them, such as the opening and closing of valves. Thought to mainly spread by USB stick, or possibly by network shares, it cannot be defeated by simply turning off Windows autorun; simply viewing an infected file system will install the malware. A security specialist at Tofino believes that this zero-day attack, which affects all versions of Windows, may have been in the wild for a month or more. Preliminary assessments indicate that the malware does not appear designed to cripple infrastructure, but rather to steal information from SIMATIC WinCC / PCS7 implementations -- i.e., some form of industrial espionage. Of course that espionage could later be used to wreak havoc on these same or similarly configured systems (Underwood, 2010).

(choose all that apply): Allow program through firewall on all three profiles and Create Firewall exceptions based on Port numbers 6) Which of the following policy modifications would make it harder for intruders to penetrate user passwords by brute force attack? (choose all that apply): Increase value of Reset Account Logon Counter After and Enable Password Must Meet Complexity Requirements. 7) Connection security rules require that network traffic allowed through the firewall use
Ping Sweeps and Port Scans Thesis Statements: In this paper I will talk about the danger that we are facing day by day from hackers and we will talk about two common network probes called Port scan and Ping Sweeps and how to protect ourselves from hem. Introduction: Ping sweeps and ports scans are common methods for hackers to try to break a network. As a system administrator this is a valid concern and for the boss this should not be a worry for him. The system administrator has a lot of steps to stop efforts from hackers to acquire any data by using ping sweeps and ports scans. If hackers are constantly thwarted and discouraged from penetrating your network they normally move on to another site.
P3 explain the security risks and protection mechanisms involved in website performance Security Risks Hackers: A hacker is someone who finds weaknesses in a computer or computer network, enters, and modifies or/and steals data this could slow down performance very much or even completely halt it. Viruses: A computer virus is a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability. Viruses can damage and/or decrease the performance of the machine they “infect”. Phishing: Phishing is the act of attempting to acquire information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity from Amazon.
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.
Digital Forensic Investigation Introduction Digital forensic involves investigations that deal with various types of data in order to preserve and capture activities that are committed illegally to be used as evidence. The investigators usually determine the source of data depending on the event they are investigating. The objective of this paper is to discuss various sources of data in digital forensic, prioritizing the discussion on malware installation, insider file deletion, and network intrusion and prioritizing each source of data according to the importance in investigating the three cases. Network Intrusion A network intrusion takes place when the network of a computer is accessed by a party that is unauthorized. This kind of intrusion can cause severe damage to an organization because files can be stolen, deleted or altered, and software or hardware destroyed.
