Internal attacks can be more difficult to find as attackers have the potential to remove any evidence of the attack more easily as they have more knowledge or access rights on the system as opposed to an outside attack. Attacks can be administrated via removable devices such as a USB that could contain some form of malware on it such as a virus. Most internal attacks are conducted by unhappy employees who want to disrupt the organisation by using the knowledge they obtained in the organisation, against the organisation. Additionally, the employee may want to gain access to important data in order to infiltrate and sell the information onto another competing organisation. The
Ohio Office/Plant. Norton Anti-Virus corporate edition and Arc Serve Backup Software is installed for security at this branch. Like mentioned before, firewall provides better security against hackers which anti-virus cannot. Firewall can reside at the hub location on the network to provide protection for the branch offices connected to it, which will end up reducing Huffman Trucking the cost of deployment (Ainsworth,
Without such a tool in place an attacker will use the unpatched device or software to gain access and manipulate the network how they please. 2. Secure Configurations for Hardware and Software on Mobile Devices, Laptops, Workstations and Servers – establishing and ensuring that proper security configurations are always in use on your operating system will keep new devices safe from outside attacks. Updating these configurations on a regular basis will also ensure that all devices connected to the system are properly secure and not an open back door for unauthorized entry. Always conduct updates and implementation of configurations on a secure channel to avoid channel sniffing.
With many network client devices, this results in the detected network displaying as an unnamed network and the user would need to manually enter the correct SSID to connect to the network. Unfortunately, turning off the broadcast of the SSID may lead to a false sense of security. The method discourages only casual wireless snooping, but does not stop a person trying to attack the network. It is not secure against determined crackers, because every time someone connects to the network, the SSID is transmitted in clear text even if the wireless connection is otherwise encrypted. An eavesdropper can passively sniff the wireless traffic on that network undetected and wait for someone to connect, revealing the SSID.
Communication Proposal and Presentation Sabrina Hunter ENG/135 August 24, 2015 DR. Franklin Communication Proposal and Presentation Firewall System A firewall is a software that stands between your computer and the internet. Having a properly functioning firewall can stop potential threats affecting your computer, but it can also alert you when a problem is occurring as well. Having a firewall can save you and your business from having to spend extra money to get rid of a virus on your computer or becoming a victim by having your computer being a hack. By having a firewall, it stands between your computer and the internet it serves to block unauthorized request passing through your system. The firewall also serves as a packet filter.
Every day, I hear about a scandal or crime involving media technology. Some argue that the solution to this problem is to get rid of it. However, making alcohol illegal did not stop others from having access. The solution is very complex and the issues may never be solved. In the meantime, use technology responsibly.
Some of the requirements would include strict control enforced via one-time password authentication or public keys with strong pass-phrases. Also, anyone trying to gain access must not be connected to any other network at the same time, aside from personal home networks under the user's complete control. Further, employees with access must not use email accounts other than the company's standards, so that personal use won't be confused with business. Users must have approved virus control and spyware protection in place on all devices accessing the company network. Remote access will be limited in certain areas, while at least Applications will be approved for access (Shared application data is an important part of Richman’s network).
Down with the Patriot Act The Patriot Act is a very controversial law. It allows the government much more room to do as they please. Some of these practices that government officials can do are monitoring phone calls, emails, and going through personal records. They say this will help prevent terrorism, but is losing one’s privacy really worth it? Could there be a better way to prevent terrorism?
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
NAC tools are different from traditional security technologies and practices that focus on file access. While file-level security is useful for protecting data, it does not keep unauthorized users out of the network in the first place. NAC technology, on the other hand, helps businesses lock down their networks against criminals. Network security measures involve three layers: perimeter security (access), authentication, and authorization and consists of questions like who you are, where you are and what do you want (Turban, 2009). Another technology is firewalls.
