Securing a Network
Kaplan University

Securing a network for a company is a very important job because without security anything can come in or be taken from the company. With securing a company I would have a firewall in place of course. A firewall is a software and sometimes hardware that screen out hackers, viruses etc. coming in from the internet (Microsoft Office, 2013). After making sure the firewall is up and running at all times I would began hardening the system. When hardening the system I will take out every unnecessary piece of item that I can without interfering with the task that needs to be done by this system. By taking these unnecessary pieces away I will be creating an easier task for myself and the firewall because, it will increase the security. I will then audit the firewall to make sure everything works properly. Once everything is checked on and I have finished making sure it is running smooth I will have an ongoing maintenance. This ongoing maintenance will detect anything suspicious and any intrusions.
A method of encrypting alphabetic: P mxlfop sy lbffdtgkee pexugbpipc. Using Vigenere Cipher I was able to come up with this Cipher. I used http://rumkin.com/tools/cipher/vigenere-autokey.php# an online cipher to help with this Cipher, using the alphabet key A and the passphrase Patsy. I believe this a very secure cipher due to the fact that there can be up to 26 different cipher alphabets. When securing the network that I have chosen I need an antivirus application, firewall, and encryption. The Antivirus is used, just as the name insists, to detect virus before they enter your computer.
There can be many threats to a WAN network, just as any other network. Businesses should take all the necessary precautions to make sure that their network is secure and protected. Physical forms of a WAN can include authentication on servers, auditing, and access controls. Electrical securities such as firewalls, encryption protocols and filtering can be used as well and are often the first line of defense for a network. There are many ways to secure and protect a WAN network and many methods, procedures, and protocols can be used together to provide the most adequate and most effective protection to a network.
Electrical securing of a network is vital to the protection of a WAN network. Many threats to a network emerge from internet usage. WAN network users should use internet policies and web filtering to prevent threats from internet usage. Policies limit the access to certain harmful websites and downloads that could spread viruses or other threats and filters monitor what is received and sent through the network to prevent threats.
Protecting the individual LAN networks within the WAN’s network system is another way that companies can protect their network. One way of protecting a LAN network can be by making the broadcasts sacrosanct. This means network designers and engineers have not permitted any connection between the broadcast LAN and any other network in the facility which makes it harder for threats to interfere during network broadcast.(Gilmer, 2007) Switching to a VPN within a LAN can help by adding encryption protection. Other ways of protection come with authentication and monitoring on severs and monitors within the LAN and overall WAN networks, this can include viral checks and other protection methods.
Physical securities can also be a part of authentication and monitoring. Having a person or system audit the network can keep out threats and prevent new threats by keeping an eye on the network and looking at what is going on within the system.
Although WAN networks have had many advancements and improvements they still have many defects that provide challenges and adequate performances when it networks are employed. One major interference with WAN networks is bandwidth speeds. Slow bandwidth speed can be caused by traffic within the WAN network. Since there is more data being sent and received using WAN networks, companies struggle with designing a network that is compatible with the amount of data transmitted within the network. Slow bandwidth speeds can cause issues with real time quality and transmissions and make the network seem inadequate. If a company invested more into its network management team then it could potentially decrease problems with bandwidth speeds. If WAN network users allotted more resources to their management teams and WAN network management teams came together to focus on the problems of each individual WAN network they would then be able to work together to find a solution that accommodates all if not most bandwidth speed interferences within WAN networks. Monitoring and measurement of service levels is an adequate way of reducing the problem as well. Taking measurements of service levels tells where the most traffic occurs and allows users to pin point where the most problems occur so there for they are able to take the proper measures to decrease the traffic in that area. Simple monitoring is vital to control bandwidth speeds. Monitoring allows WAN users to better understand their network and the specific defects that it has. Routine monitoring can take into account measurements and traffic levels. It gives management a way of looking into the network.
Security is an important aspect of every network. Every network needs to be protected to insure the privacy of its data and to protect it from harmful threats. Securing a network takes a team which includes physical and electrical aspects as well as people and technologies. There are a variety of ways to secure every network and some require more security than others. All in all security is a part of the functioning of a network from start to finish and should be a top priority of any network user.

Case Study - Securing the Network

...Case Study Strayer University SEC 305 It is vital to ensure the safety of a central computer system that is accessed by multiple branches, staff members and remote users. The diversity of an enterprise environment dictates the need to consider multiple aspects when planning for access. Normally, an internal LAN is considered a secure network. Due to its broadcast nature, wireless communications are not considered as secure. Such networks are vulnerable to eavesdropping, rogue access points, and other cracking methods. For remote access, VPN solutions such as dial-up, IPSec VPN, and SSL VPN are commonly used and any access to data center devices must be protected and secured. In the data center, access lists are used to prevent unauthorized access, and reverse-proxy servers use authentication mechanisms to provide a higher degree of security for applications. The need for security is constantly evolving. Maintaining individual security methods for each access scenario can be expensive. There are better alternatives for securing enterprise access. Some that is cost-effective, easy to manage and secure, while addressing performance and scalability requirements. Basic security requirements consist of: • Verification of user credentials and services to define user access. • Client integrity checks that consists of endpoint security verification and of redirecting users to predefined subnets to download compliant anti-virus software...

Lab #10 Securing the Network with an Intrusion Detection System (Ids)

...Lab #10 Securing the Network with an Intrusion Detection System (IDS) Introduction Nearly every day there are reports of information security breaches and resulting monetary losses in the news. Businesses and governments have increased their security budgets and undertaken measures to minimize the loss from security breaches. While cyberlaws act as a broad deterrent, internal controls are needed to secure networks from malicious activity. Internal controls traditionally fall into two major categories: prevention and detection. Intrusion prevention systems (IPS) block the IP traffic based on the filtering criteria that the information systems security practitioner must configure. Typically, the LAN-to-WAN domain and Internet ingress/egress point is the primary location for IPS devices. Second to that would be internal networks that have or require the highest level of security and protection from unauthorized access. If you can prevent the IP packets from entering the network or LAN segment, then a remote attacker can’t do any damage. A host-based intrusion detection system (IDS) is installed on a host machine, such as a server, and monitors traffic to and from the server and other items on the system. A network-based IDS deals with traffic to and from the network and does not have access to directly interface with the host. Intrusion detection systems are alert-driven, but they require the information systems security practitioner to configure them properly. An IDS provides...

Securing and Protecting Information

...Securing and Protecting Information Jane Doe CGMT/400 March 9, 2015 John Doe Securing and Protecting Information As the most important asset within the organization it is necessary to provide measures that can effectively protect data from loss and unauthorized intrusions. Information security involves authenticating users with a high level of protocol and promoting accountability within the information infrastructure. This approach may involve use of the organization assets, identification, authentication, authorization and the use of third party security systems or devices to protect data from unauthorized access. Security Authentication Process The security authentication process is the first step in information security and assurance. This process involves “binding a specific ID to a specific computer connection” (University of Phoenix, 2011) in order to authenticate access to the information system. During this process the user provides a user ID and password to the computer system or remote server to verify his or her identity. Authentication is accomplished when the system or server matches the user ID to a specific password and grants the user remote access to system resources. Identification The identification process is an access control element designed to match a user to a specific process. The identification process is performed the first time a user ID is issued to a specific user. User IDs have unique values and can...

Network Hardening

...Network Hardening Client side attacks are attacks that target vulnerabilities in client applications that interact with a malicious server or process malicious data. Here, the client initiates the connection that could result in an attack. If a client does not interact with a server, it is not at risk, because it doesn’t process any potentially harmful data sent from the server. Merely running an FTP client without connecting to an FTP server would not allow for a client-side attack to take place. Simply starting up an instant messaging application potentially exposes the client to such attacks, because clients are usually configured to automatically log into a remote server. With this client server diagram there is only one firewall posted between the internet and the web server. I would consider placing a firewall between the wireless and the switch. Modern firewalls have the capability to function as a router, opposing the need of additional device on the network. However, if you have a large number of hosts in the Demilitarized Zone DMZ, you may wish to consider a router with fundamental filtering rules; placing one on the network can reduce the load on the firewall itself. The network has only one mutual Internet connection; I would protect it by enabling Internet Connection Firewall. Internet Connection Firewall can only check the infrastructures that cross the Internet connection on which it is enabled. Because Internet Connection Firewall works on a per connection...

Wlan Security

...WLAN, and the ramification if the WLAN is breached. Sebastian Bach Two ways to secure a WLAN, and the ramification if the WLAN is breached. There is an added vulnerability when securing a WLAN than there is with a LAN. The multitude of packets floating around going from one or more access points to a variety of electronic devices can be a tempting arena for those wanting to gain illicit access. There are several ways to increase the security level of a WLAN. The most basic of these would be a router with an integrated firewall. This is almost exclusively found in residential settings. Keeping to the same architecture, firewalls can be quite complex in their modus operandi. Where basic firewalls work on the first three or four layers of the OSI model, the more complex firewalls operate on all seven levels of the OSI model. Often times accompanying these higher end firewalls, there is what is known as a bastion. A bastion is located on the public side of the firewall and acts as bait for would be attackers. The thought behind a bastion is to get the would-be attackers to go there, thinking they have accessed the protected network. Bastions are completely unguarded to make this process easier. Another method of making a WLAN secure is to encrypt data that is on the network. If this is done, the users will authenticated, which will yet again further strengthen the WLAN. For this it is recommended to utilize either WPA or WPA 2 wireless encryption. In conjunction to...

Preventing Security Breaches

...year. What can be done to prevent the release of potentially sensitive information? There are several precautions that can make a big difference when it comes to security breaches. Three of the most important are keeping software up-to-date, securing your network and properly training your employees. Keep Software Up-to-date Earlier this year, thousands of Oregonians who used state websites to pay child support, file unemployment claims and renew their vehicle registration were left vulnerable to attackers who could intercept Social Security numbers and other sensitive information. This vulnerability was due to the use of outdated encryption protocols on the state of Oregon’s websites. One of the easiest ways to avoid security breaches is simply to keep all software and systems up-to-date. Using outdated encryption, last year’s virus protection software or an operating system from 1998 is a recipe for disaster. Secure Your Network During late 2014, the State Department revealed that hackers had breached its unclassified email system. While the government claims that no sensitive information was lost, we have to wonder: why wasn’t this “unclassified” network encrypted with the same strength as its other networks? Securing networks by password protecting them and encrypting them is another easy way to avoid data breaches. Hackers are far more likely to take advantage of “low hanging fruit” than...

In order to maintain the highest level of security within the os servers you must first have knowledge of the vulnerabilities of the running operating system. It is those vulnerabilities in the system that the intruders will be searching your network for. The known shortcomings and vulnerabilities of Windows and Unix/Linux servers have dysfunctions that can be exploited to gain access to a company’s private information. This information in the wrong hands could cost an organization millions of dollars in security damages. One of the ways to prevent this type security breech is to make sure that your Windows and Unix/Linux servers has the right up dated patches for these operating systems. According to, (Conklin, W.
