Tip # 5. Don't forget anti-virus software. Even if you have gateway security protection and anti-virus software running on clients, you should still run suitable enterprise-grade anti-virus software on your file server. Most enterprise products allow you to update virus signatures from a local update server (or even from other clients running the software on your network), but if you isolate your file server from the Internet then you may not be able take advantage of network-based reputation systems for additional
Attackers are always looking for devices and software that are newly added to a system and not updated correctly with the security measures in place already. This is the door they look for to get in. A method to avoid such opportunities is to deploy an automated asset inventory discovery tool and use it to build a preliminary asset inventory of systems connected to an organization's public and private network. This will help make the system capable of identifying any new unauthorized devices that are connected to the network within 24 hours, and of alerting or sending e-mail notification to a list of enterprise administrative personnel. 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.

Networked Systems Security Task 1 – THREATS AND IMPACT OF NETWORK THREATS There are many types of threats that can damage your computer either temporarily or permanently. Some threats posed may not threaten your computer right away however have the potential to do so. Some threats that present themselves can include physical threats such as the theft of equipment whether that is the monitor, computer etc. Other threats can be harder to find such as viruses, worms or any kind of malware. Understanding these threats allows the organisation to prevent, protect and correct any damage done to his/her computer to an extent.
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
Corporations, government services, and education should have an intrusion detection prevention system (IDPS) in place. This tool that is in line with the network helps network administrators determine who has access to certain servers and other network devices. IDPS can also prevent intrusion from unwanted users from the outside trying to hack into a data center. It is important that the information security policy states what users have access to what servers. Users from within the organization are most prone to be the attacker and cause disruption on
How can a user demonstrate that their computer or device is malware free? By periodically performing real time scanning on system for malware that might have been missed by malware shield. 3.

Communication Paper David Brinkley HCS/490 Russell Wet stein August 6, 2012 Introduction One specific mode of communication used by consumers and health care providers is Email. It is a mode that will be discussed to give you information on the importance of how efficient and secured it can be when properly used. There are benefits and downsides that will always have questions on emailing, but making sure the correct security is implemented there can be some advancement. Emailing can be as simple as transportation secured documents to one specific person. With the security such as firewalls can now slow down hackers and make it much more difficult.
Deliverables When discussing the risks, threats, and vulnerabilities within a workstation domain, we must not only know the potential issues, but we must also know what can be done to alleviate those issues. Risk, Threat, or Vulnerability Mitigation Lack of user awareness Conduct security awareness training User apathy toward policies Conduct annual security awareness training, implement acceptable use policy, update staff manual and handbooks Security policy violations Place employee on probation CDs and USB drives disable all CD drives and USB ports File sharing Disable all websites to where only work relates sites can be accessed Passwords ensure all passwords are kept safe and secure by training all employees. E-mail only allow
Finally they will need Microsoft access for when they will be using databases for their work. Back-up Software Students will need some sort of backup software which saves a backup file of their work just in case they accidently delete or somehow lose their work. Anti-Virus/spyware Antivirus and spyware software would be very important as the virus may be able to take control of their computer and randomly delete files which could crash and destroy the computer and making all programs and work they had gone. Spyware could steal their work and have access to personal stuff stored on the
