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
There are VPN gateways that offer native malware mitigations and firewall services as integrated spec. Decru is an excellent company to choose when dealing with network security. They offer two security plans, DataFort E440 for file based NAS and DataFort FC440 for block based SAN. Depending upon what platform you go with, there are two options to I recommend you go with one of the two security
Sean Dobelman SEC280 Week 1 Case Study Ping sweeps and port scans are two common network probes used as cracking tools by intruders. Network probes are technically not intrusions on a computer or system, but they should not be taken lightly as they may lead to actual intrusions in the future. A port scan is a method used to discover what services are running on a computer. Whereas a ping sweep sends a set of packets to a network of machines to find out which ones respond. They are both common types of “information gathering” to help devise a course of action by intruders.
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.
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.
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.
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).
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.
System administrators should be monitoring network traffic for any unauthorized access to data. Training is the next important tool that should be incorporated into any security planning. Many users have computer experience and may know how to logon and complete their daily responsibilities, but that does not mean that they do not require any training. Many users may have never had any training or experience with common threats and how to avoid
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.
