Case 5 Security controls are technical or administrative safeguards or counter measures to avoid, counteract or minimize loss or unavailability due to threats acting on their matching vulnerability, i.e., security risk. Controls are referenced all the time in security, but they are rarely defined. The purpose of this section is to define technical, administrative/personnel, preventative, detective, and corrective compensating controls, as well as general controls. Basically they are categorized in following way • Preventive • Corrective • Detective Secure Configurations for Network Devices Think about firewall, switch, and switch arrangement against standard secure setups characterized for every sort of system gadget being used in the association. …show more content…
Ensure the authorized configuration and security profile contains documented owner of the connection and a defined business need. Organizations should deny access to those wireless devices that do not have such a configuration and profile. Ensure that all wireless access points are manageable using enterprise management tools. Access points designed for home use often lack such enterprise management capabilities, and should therefore be avoided in enterprise environments. Network vulnerability scanning tools should be configured to detect wireless access points connected to the wired network. Identified devices should be reconciled against a list of authorized wireless access points. Unauthorized (i.e., rogue) access points should be …show more content…
The security configuration of such devices should be documented, reviewed, and approved by an organization change control board. Any deviations from the standard configuration or updates to the standard configuration should be documented and approved in a change control system. At network interconnection points, such as Internet gateways, inter- organization connections, and internal network segments with different security controls implement ingress and egress filtering to allow only those ports and protocols with an explicit and documented business need. All other ports and protocols should be blocked with default-deny rules by firewalls, network-based IPS, and/or routers. All new configuration rules beyond a baseline-hardened configuration that allow traffic to flow through network security devices, such as firewalls and network-based IPS, should be documented and recorded in a configuration management system, with a specific business reason for each change, a specific individual’s name responsible for that business need, and an expected duration of the need. Network filtering technologies employed between networks with different security levels (firewalls, network-based IPS tools, and routers with access controls lists) should be deployed with capabilities to filter Internet Protocol version 6 (IPv6) traffic.

The current architecture of the Riordan Manufacturing Company Inc. Wide Area Network (WAN) and network security in place requires updated documentation. The purpose of this paper is to consolidate the existing information into a single format and evaluate the WAN and security documentation for an executive overview. Riordan Manufacturing, Inc. is an industry leader in the field of plastic injection molding. With state-of-the art design capabilities, they create innovative plastic designs that have earned international acclaim. Attention to detail, extreme precision and enthusiastic quality controls are the hallmarks of Riordan Manufacturing. With facilities in San Jose, California, Albany, Georgia, Pontiac, Michigan and Hangzhou, China, the company is heavily dependent upon their communication networks. The documentation produced by this analysis will give the management at Riordan Manufacturing an understanding of their current network topology and a baseline to evaluate security of the network.
It is best to prevent security incidents from occurring in the first place – therefore prevention should be a top priority for the IT staff at CEG. The National Institute of Standards and Technology (NIST) recommends five main categories of incident prevention; risk assessments, host security, network security, malware prevention, and user awareness training (Cichonski P., Grance T., Millar T., & Scarfone K., 2012 p.24). Risks of the various types of possible security incidents should be identified and prioritized based on likelihood and potential harm. Risk assessment should be periodic and ongoing. Host security is achieved by hardening each host on the network. Host hardening includes keeping current on the latest software patches, enabling and monitoring audit logs, and assigning permissions based on a system of least privilege. Network security is primarily concerned with securing the perimeter of the network to prevent unauthorized intrusion. This includes the use of firewalls, intrusion detection systems (IDS), securing VPN, and blocking unnecessary ports. All hosts on the network must run and regularly update malware protection software. And all employees should...
As an IT manager It has probably already been beaten into you that you must use Wi-Fi Protected Access. However, it shouldn’t stop there. Other aspects for your business to consider is the ability to support a high-density of mobile devices, PCI Compliance, or HIPPA Compliance and Reporting? Is ease of deployment and use important because of limited IT resources? Is your business looking for additional features such as social login, analytics and so on...
The WPS protocol relies on an eight digit Personal Identification Number (PIN) to allow the authentication of users on to the network. The protocol further relies on a session of eight Extensible Authentication Protocol (EAP) messages that are followed by a final message which identifies the successful completion of the session. WPS automatically configures the network name (SSID) and the WPA security key for the access point and the WPS enabled client. The benefit is that a user does not need to know what the SSID or the passcode or security key is.
Every organization, big or small, should have some level of security policy to protect their proprietary information. While the intensity and depth of an organization's security policy depends heavily on the nature of their business, common guidelines are mentioned in this paper that apply to all policies. One of the most important things to remember is that employees are a critical component to a successful security policy. It is the organization's job to ensure that their security policy is widely distributed and understood.
Properly secure wireless systems: - To prevent data breaches it is very important to secure wireless networks. WI- Fi network security is necessary because it is very easy to hack the data and unauthorized access. Breaches can be prevented by using strong passwords, encryption methods, and strong verification.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
Authorization controls to restrict access to authorized users. These controls are implemented with an access control matrix and compatibility tests.
The security topology will determine what network devices are employed at what points in a network. At a minimum, the corporate connection to the Internet should pass through a firewall. This firewall should block all network traffic except that specifically authorized by the security policy. Blocking communications on a port is simple; just tell the firewall to close the port. The issue comes in deciding what services are needed and by whom, and thu...
Scenario 2: A Terrorist is war driving on the streets, hunting weak APs with poor security (like WEP). Once such an SSID is found, a cracking process is initiated. Once the cracking process successfully reveals the ‘secret key’ used for authentication, a connection is made to the AP and communication can be initiated.
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
With a rise in security breaches experienced by companies in the last few years, it is no wonder that businesses are implementing stronger security policies. Two topics that deserves to be addressed by businesses are PC protection software and external access to corporate networks. There may be no sure way to prevent attacks on the corporate network but there are steps companies can make to limit such activities. This paper will discuss the possible guidelines that companies may implement to strengthen security policies.
commercial purposes are different than the access points that are used for the residential purpose.
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
...that permits traffic and one that exists to block traffic. Whether a company wishes to place more emphasis on permitting or blocking traffic is up to the individuals who set the security policies for that company. A company should not leave this to the discretion of the service or product that will supply the security because only the company knows what kind of protection it needs. If a company is unsure about what kind of protection is necessary, there are numerous vendors that will help set up a secure network (see Chapter 4).
