1) Distinguish between EAP, TACACS+, and RADIUS in terms of functionality.
EAP (Extensible Authentication Protocol) is an authentication technique that uses public and private key pairs created and implemented for authentication.
TACACS+ (Terminal Access Controller Access-Control System), it uses TCP Protocol and Port 49. Also it encrypts the entire payload and separates Authentication & Authorization.
RADIUS (Remote Access Dial-In User Service) uses UDP Protocol and Port(s), of 1812 & 1813 -or- UDP: 1645 & 1646. However, it encrypts only the Password Field and combines Authentication and Authorization ("TACACS+ and RADIUS Comparison," 2008).

Malware consists of viruses which are programs that attach themselves to legitimate programs on a victim’s machine. Worms are standalone programs that do not attach themselves to other programs. Direct propagation words take advantage of vulnerabilities in software. Blended threats propagate both as viruses and worms however; they post themselves on websites for people to download unwillingly. The payrolls are being nine they merely pop up Ace message on the victims computer screen or do something unknowing but nonlethal damage. Trojan horses, hides itself by deleting a system file and taking on the system file name. Remote access Trojan gives the attacker remote control of your computer. These items mentioned above do not rename themselves they can cause great damage or be just a nuisance.
6) How does the use of border, internal, and host firewalls provide defense in depth?
Border Firewall, stops simple high-volume attacks and insureds that responses to external scanning probes cannot reach an external attacker. Internal Firewall, controls traffic flowing between different parts of the firms internal network. Host Firewall, generally need to allow external access on TCP ports 80 (HTTP) and 443 (HTTP over SSL/TLS).
By using the border, internal and host firewalls, this is what creates defense in depth. Because an attacker must defeat all of these devices in order to get into a company’s network to cause great damage (Boyle & Panko, 2015, pp.
The particular operate on the firewall in a organization is actually in order that just about all unwanted things to do are usually impeded which includes cyberpunks that will get critical and also delicate information on the business. Hacking is a really unsafe exercising wherever offender may access quite information a business has and also use this information throughout blackmailing the business as well as customers. Marketing software’s additionally takes on a significant position throughout acquiring the businesses multilevel protection. It has got the features involving sensing infections that could invasion a corporation and also help to make a corporation shed its critical information. AVG is just about the best ensuring that multilevel protection is actually preserved. The virus separate from the virus that detects other virus’ have the ability to use web firewall and also find virtually any spyware and adware that an organization may be being affected by. It really is accurate that an organization will need to have both hardware components and

“Security needs to be addressed as a continued lifecycle to be effective. Daily, there are new attack signatures being developed, viruses and worms being written, natural disasters occurring, changes in the organization workplace taking place and new technologies evolving, these all effect the security posture in the organization” (King, 2002). This being said, it is important to evaluate firewall and router rule sets more frequently. The possible threats against this policy include improperly configured network infrastructure which leads to a domino effect that could start with malicious programming which could end in data loss. Many of these threats may be unintentional as some users may not be aware of the risks and how their processes and procedures open the door for such attacks. For this reason alone, a more frequent evaluation is needed. This vulnerability could lead to data loss and the exposure of trade secrets, client lists and product design. The exposure of such information for most companies could mean a financial collapse as it no longer has the competitive edge that makes it the industry leader. While the likelihood of this threat is very high, “security risks to the network exist if users do not follow the security policy. Security weaknesses emerge when there is no clear cut or written security policy document. A security policy meets these goals:
This is an open exposure due to the uncertainties of the internet. Controlling access to information systems and associated networks is necessary for the preservation of their confidentiality, integrity, and availability. Confidentiality assures that the information is not disclosed to unauthorized persons or processes. Any automated attacks or personal attack or attack to exploit the company secrets/statistics/data is the biggest threat to that may occur without the firewall.
TACACS+ was developed by CISCO is the new open standard for remote access and uses the authentication, authorization, and accounting (AAA) architecture. TACACS+ provides a quick and easy merging with the current network. The implementation of TACACS+ will provide the employees of The 9-Iron Country Club with everything they have requested. TACACS+ will continue to provide the needed remote access solution with its updateability for many years to come.
A firewall is a network device, hardware, software, or a combination of the two, whose purpose is to enforce a security policy across its connections. It is comparable to a wall that has a window where the wall serves to keep things out, except those permitted through the window. A security policy acts like the glass in the window; it permits some things to pass, light, while blocking others, air. The heart of a firewall is the security policy that it enforces.
All the activity, whether approaching or active, must go through the firewall; just approved movement is permitted to go through it. Firewalls make checkpoints between an inner private system and the general population Internet, otherwise called gag focuses. Firewalls can make gag focuses taking into account IP source and TCP port number. They can likewise serve as the stage for IPsec. Utilizing burrow mode capacity, firewall can be utilized to actualize VPNs. Firewalls can likewise constrain system introduction by concealing the internal network system and data from the general population
Another firewall architecture that is used in today’s networks is the Screened Host Architecture. It is also called the Screen Host Gateway. A screened host architecture provides services from a host that 's attached to only the internal network, using a separate router (O’Reilly Building Firewalls). The primary Security feature that is provided with this architecture is packet filtering which is done by the screening routers used. This type of architecture uses a screening router (like in a single-box host), but also uses something called a “bastion host” (O’Reilly Building Firewalls). The bastion host is going to sit on the internal network and
For firewall to be implemented as application. It is done by the following way, if it is tcp port 25 drop it. It is also possible to use local logic which resides in the remote switch router. This combines both. The other method is, if anything is not matched then forwards the packet to the control plane and it decides and make a decision on the best method to forward the particular packet on the best network. The addresses are typically referred to rules. In this case if the destination address is assigned as 10.x.x.x then it will constitute a rule. And when the rule is met it follows the action. The statistics is the ability to count the number of packets to be forwarded to that port. All this information can be fed up to central controller. Since we have a central controller in the network a lot of intelligence can be provided to the network. At present there is one single point within the network which has a good overview of a network conditions. So in case of Network failure the applications of central point can react very quickly to reroute the traffic.
According to Managed Firewall (N.d.), Firewall management is a security service which prevent unauthorized access and costly breaches in the organization’s system. This service requires a high level of expertise in order to manage and control the system, in which the network traffic must be monitored incessantly to protect from cyberattacks before the devastation is done. As mentioned in Harrison (2011), it defines firewall as gatekeepers for the corporate network and data center perimeters. The procedure of Firewall is to control and scan the network
