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.
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
Vanorian Purley Professor Timothy Gillin CIS 333 June 17, 2013 Analyze and assess any potential malicious attacks and threats that may be carried out against the network. Malicious attacks are brought about by human beings with the willingness to provoke damage. They are critical for the infrastructures’ security. Malicious threats are potential hazards that can materialize as attacks such as threats cause damage, when executed as offensive actions. Attacks are the actual implementation of threats, and therefore, they are the effective cause of damages.
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.
Once the intruder knows the machines that are alive or not, they can begin to focus on what machines to attack. A network administrator may have legitimate reasons to perform a ping sweep for diagnostic purposes. A tool used for implementing a ping sweep is fping. fping works by taking a list of IP addresses and sends packets to each of them, one ping packet to one IP address,
A port scan is a technique used by intruders to discover the services running on the object machine. The intruder can plan an attack on any unprotected service that it finds. For example, if the intruder finds that a port is open, it could continue to find out what type of IMAP is running on the objective system. If the version is at risk, it could be able to get access to the system using an “exploit” (a program that exploits a security hole). A port scan is essentially very simple to implement.
These ads get in the way of the viewers screen and will most of the time trick you into clicking onto the pop up, which unethically redirects you to another web page. It may even make you click in an area that authorizes an installation of some sort of adware to your computer. Lack of online B2C ethics has been a large contributor to identity theft and internet fraud. In conclusion, there are many legal and ethical concerns with online B2B and B2C sites. Since most of the internet is unregulated it is important to research companies that we consider doing business with from the B2B or the B2C perspective.
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.
Many credit reporting systems that use internet as a mean to transfer credit data is insecure. Security holes can exist in several main parts of the credit reporting system such as data transfer, database, interface and network. When a user order and receive information, data are transferred through the internet where hackers can listen in and intercept the data if it’s not properly encrypted. Logins, passwords and
VPN outfits its privacy by way of channeling and security measures. Channeling is a way that packets from one protocol are enclosed inside another protocol. There are a lot of hackers these days sending viruses, malware, and other bugs. It is important for a company to stay protected so that they don’t lose private information or open viruses that could temporarily shut a company down. Remote-access VPNs allows you to securely access corporate resources like servers, computers, and multipurpose printers.
