Internal Monitoring Insider Threats Internal monitoring starts with monitoring access and usage of an organizations network. This is because insider threats are a very serious threat. Insider threats can come in the form of both intentional and unintentional misuse of the system. An intentional misuse to the system can come from a disgruntled employee who may seek to damage the company or find personal gain from exploiting data. Unintentional misuse happens when users are not properly trained on the system.
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
Another risk could be a possible internal breach of security vulnerabilities such as cross-site scripting and SQL injections that could be exploited by either an unauthorized user or an employee via the internet or the intranet that could compromise the confidentiality of sensitive information. Two more probable risks would be not having a proper disaster recovery policy in place and the data not being correctly backup and the use of a single-on to every computer which could lead to unauthorized access. My current healthcare organization can mitigate the risks by implementing the proper information systems policies that to protect the organization from any unauthorized user. These policies should include how to protect and how to use the IT technology such as making sure you log off when you leave your computer unintended
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.
Attacks are the actual implementation of threats, and therefore, they are the effective cause of damages. Malicious threats are selective: The more the target can produce disruptive effects, the more it is likely to be attacked; the more the target is protected, the less likely it will be attacked. Attacks are carried through as processes, where actions of the attackers and defenders follow and affect each other. In other words, an attack is a chain of mutually dependent offensive and defensive events. In few occasions, the hostile part of an attack can consist of just one step, but more generally, it will comprehend several steps, possibly organized in successive phases.
Concealing Fraud Investigations and evaluating security There are some key points to think about when concealing a fraud investigation. One main point is if there is a whistle blower involved this person’s identity must be protected. The whistle blowers information can be a very valuable if managed correctly. I would also keep the number of individuals that now about the investigation at a bare minimum. This will greatly reduce the risk of evidence being destroyed because of a leak.
Since confidentiality is an issue, smartphone transmissions signals can be hacked by accidental broadcast. Third party snooping, can hack blue tooth signals that transmit confidential information. Stolen phones create a threat to business and the community through fraud. Training employees can be a measure to minimize the risks that poses a threat to cell phones. Some measures to help in information security could be aimed to data encryption, passwords, software, network security solutions and service companies offering voice encryption.
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.
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.
