If hackers are constantly thwarted and discouraged from penetrating your network they normally move on to another site. With proper instruction, the right software and sufficient support, one can take necessary steps in preventing malicious types of activities in a network. Port scans and ping sweeps may seem dangerous, but they can also be understood and monitored in order to identify and defend against network threats. Technology has changed a lot with in past teen years, there is much more important information on the web and on the clouds such as personal information, company or business documents, all of our financial records and many more, and there are many unethical people out there that are trying to take an advantage of these great technology’s and still from others! Network probes are very easy ways to detecting intrusions.
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).
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.

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
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.

Remote-access VPNs allows you to securely access corporate resources like servers, computers, and multipurpose printers.
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
The ping sweeps and port scans are the two techniques that malicious computer users such as hackers that can use to compromise an Enterprise networks security and gain access to their proprietary data. The ping sweeps are performed to find an open-door into a particular end-point. A person usually can find all kinds of utilities on the internet to exploit the open-doors on the system and gain access to important and confidential files on the network. It is a good idea that we try to protect ourselves against all these types of activities on the network and to also try to conduct them ourselves that way we know that out networks are safe. The ping sweeps are what you really think they are.
