Malicious damage: Examples can be Viruses, Worms or Trojans a. Internal attacks come from within the organisation by disaffected staff. Individuals or a group have authorised access and privileges to the organisations network. They may use their knowledge on the organisations network to exploit or interrupt its functions. 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.
Unit 32 Networked Systems Security Name: P1 | describe how networks can be attacked | Attacks: types e.g. denial of service, back door, spoofing, mathematical, brute force, software exploitation, viruses, rootkits, worms, Trojans, spyware, adwareSources of attacks: internal e.g. disaffected staff; external e.g. via internet connections or through unsecured wireless access point, viruses introduced by email | U4U8 P3 | P2 | describe how networked systems can be protected | Email systems: security features e.g. secure MIME, spam, hoaxing, relay agentsWireless systems: security features e.g.
2. Which of the following standalone devices can be found near the Internet edge, with a primary purpose of providing some type of network security between an enterprise or SOHO TCP/IP network and the Internet? (Choose two answers.) a. LAN access point b. IPS c. Analog modem d. Firewall Answer: B, D. A firewall normally sits inline, in the packet-forwarding path, choosing which packets to allow and disallow. An intrusion prevention system (IPS) can sit inline or outside the packet-forwarding path, reporting on complex attacks based on combinations of events.

1. What does malware free mean? By using anti-malware software products and to shield system from malware such as virus and worms. 2. How can a user demonstrate that their computer or device is malware free?
So the old data will not be sent to the web server 7. What is the result, and what does the result indicate? Internet Explorer cannot display the webpage. The firewall must still be set 8. What other test could you perform to prove that it was your computer’s firewall that was blocking the connection and not the firewall on the computer you are using as a client?
7. What is the difference between software RAID and hardware RAID? Hardware RAID offers better reliability compared to software RAID. A software RAID can be prone to data corruption, due to the fault of the RAID software or driver that is being used. A software RAID can also be affected if the host computer is heavily loaded.
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.
I would implement firewalls, cryptography, antispyware, antivirus, and content filtering. These will be installed in various levels of our network infrastructure including, our mail servers, gateways, laptops and desktops. When these security technologies are in place a threat may be able to bypass on level of security but will be detected and eradicated at another. Layering our security in this manner will mitigate the risks of an employee disabling their protection on the workstations. Our mail servers which send, receive and store emails must be secured as well.
