Network Security Paper University of Phoenix NTC/360 August 9‚ 2005 Installing firewall or anti-virus software on enterprise workstations can help prevent some of the security problems the Internet can cause; but not everything. By understanding the different Open Systems Interconnect (OSI) levels and security threats involved with each one of them‚ it is easier to plan a strategy to combat security problems. Purpose and Scope To cover all areas I have listed the network security measures

access‚ and behavior‚ as well as the new threat landscape‚ leading organizations to rethink their network security strategy. However‚ traditional methods like virtual LANs (VLANs)‚ switch access control lists (ACLs)‚ and port-and protocol-based firewalls do not provide the application visibility and user access controls to effectively secure a network segment. Organizations require a network security platform capable of creating relevant network security policies by application‚ user‚ and content

Jeramie Feenstra Richard De La Cruz Window 7 vulnerabilities Local Security Authority Subsystem Service There is a recently discovered vulnerability in the Local Security Authority Subsystem Service which can cause a denial of service attack if a hacker sends a packet containing malicious files during NTLM authentication. NTLM protocol refers to the Windows NT LAN Manager which is used to authenticate logons to PCs that are connected to the network. The security update provided by Microsoft includes

File Transfer Protocol (FTP) server we have running and switch it over to use secure FTP so that only users allowed on our system can access our FTP server. In the WAN domain‚ we need to make sure that we have firewalls set up on our network that will filter all incoming traffic. This firewall will stop all traffic coming on to our system that is not meant or not wanted our network. In the Remote Access Domain‚ we need to establish strict user password policies‚ as well as lockout policies to defend

SEC280 March 10‚2011 Ping Sweeps and Port Scans: Should we worry? Ping Sweeps and Port Scans are the two most common network probes that serve as important clues in sensing invasion or intrusion that can harm a network. Network probes are not actual intrusions‚ although‚ they could be potential causes of actual intrusions. Port scans and ping sweeps can lead to an intrusion of companies network system‚ however‚ with today’s technological advancements‚ these activities can be detected

Differences between Viruses‚ worms‚ and Trojan Horses Computer viruses are man-made program or a piece of code which can load onto your computer without your knowledge and cause damage to your computer system. The dangerous part of the computer viruses is they are attached to a file or program‚ which means the computer viruses will not running until you click the file or program‚ and even more dangerous type of viruses is one capable of transmitting itself across networks and bypassing security

The external attackers can be counter by our Intrusion detection systems but can be block by our firewall and Intrusion prevents systems. We will fortify our application securities as well with the implementation of a strong access control list. This is an outline we will Use TCP/IP and IPsec filters for defense in depth.

Problems‚ challenges at CB Hart that are addressed and which solution is proposed for. Following the recent data leakage from the Hale firm I suggest that cryptography is used as a prevention measure to avoid similar issues. Business relies to certain extent on mobile technology and portable storage devices to communicate and exchange data faster and easier. Encrypting data is very efficient method to protect sensitive information. In such a merger it is important to keep a safe internal network
