Physical Threats Threats can come from many sources and can affect different parts of a system and network. There are physical threats that can compromise a system and deny the use of network resources. Damage can occur on any piece of hardware connected to the system such as servers, routers, switches, and workstations/ PC’s. Access should be controlled to the location where vital hardware is stored. Ensure all doors remain locked and only authorized individuals enter restricted areas. There can also be damage caused by electrical threats. A voltage spike or total power loss can shut down critical systems and cause negative impacts throughout the company. The APC Smart-UPS RT 5000VA 230V will continue to provide emergency power for existing stores and the new stores. The server rooms will remain environmentally controlled to avoid temperature extremes. The store policies should address maintenance issues for all network equipment to avoid issues later on. Network Threats Threats can happen on a network regardless of the type, whether wired or wireless. Providing adequate security for the network should ensure minimal disruptions. The network threats can be broken into four classes to include: structured threats, unstructured threats, internal threats, and external threats. Structured threats usually come from individuals who have extensive knowledge of computer systems. These experienced hackers will attempt to extract information, commit fraud, and destroy or alter records on the targeted network. They will use whatever means they can to collect information about the systems on the network including phishing, pharming, and spoofing. Making company employees aware of these tactics can help prevent them from disclosing vital inf... ... middle of paper ... ...fluence the speeds on your networks and the connected devices. Three types of cabling are commonly used; coaxial, twisted pair, and fiber optic. Each has its own advantages and disadvantages. Kudler Fine Foods has a twisted pair or 100BaseT LAN network that uses Cat-5 cables. This has the amount of speed needed for the network to run. The connection between stores are dedicated T3 lines using coaxial cable with speeds of 44.736 Mbit/s. There is also a dedicated OC-1 line connecting the home office to each store. This line is a SONET line with transmission speeds of up to 51.84 Mbit/s. Conclusion A network faces physical and network threats that disrupt or compromise system resources. Preventative measures are used to protect company assets. A network has many building blocks associated with it, each piece can affect how the network runs, and how it is protected.
The physical security field can be broken down into two very general but separate areas: types of security and security components. The Types of Security outlines different areas or sectors where why and how security is conducted differ. Security components break down Physical Security even further, speaking to the more intricate areas of any Security type or team.
Physical and environmental security programs are generally considered to be a collection of mechanisms and controls put into place that help ensure the availability of information technology capabilities. These programs protect an organization from fire, flood, theft, power failure, intentional, and even unintentional damage through negligence. Implementation of these programs at the organizational level can take place in a number of ways but most organizations choose to follow the application of a body of standards, usually set forth by an organization such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Once such body of standards put forth by ISO/IEC is 27002, Information technology – Security techniques – Code of practice for information secur...
The staff and clientele of Home depot do not know simple preventive measures of cyber-attacks that could cause security breach(Donaldson,2015). There is no strong awareness of cyber-attacks that can be provoked by using a USB, CD, iPhone or any removable device plugged into the company’s computers(Manning,2009). Majority of Home depot staff do not no know the difference cyber-attacks the company might be vulnerable to. Because there is no frequent training on enterprise cyber-attacks and simple preventive measures most of Home Depot staff from management to the laborers in different stores in the US, Mexico and Canada expose the company to attacks such as social engineering, Malwares, DoS and other common cyber-attacks hackers could use to penetrate the company to steal sensitive information and cause serious security breach that will cost the company a lot of quantitative and qualitative damages(Stewart, et al.,
A public utility company employed SecureState to repair their internal and external network security. Consequently, SecureState was able to access the network due to a variety of exploits. Many threats would not be present if systems were updated with the latest operating software and patches and were properly configured. This engagement revealed several critical problems within the client’s system, allowing SecureState to gain access to more resources than intended. The improperly segmented networks combined with easily exploitable vulnerabilities can allow attackers to gain access to entire networks potentially causing untold levels of damage.
...ional standards. Our Security index remained steady as our control measures met the goal of being proactive enough to prevent, sustain, and repudiate a good amount of cyberattacks. The downtime, unfortunately, was more than we planned. But unlike other sectors, the electrical grid is a more complex system when one area is affected. It often requires isolation of systems to get the components back on line and at full operations range before restoration commences. Isolation can also translate to the significant amount of time to properly re-cycle the systems before it is ready to be integrated into the grid. Lastly, the profit margin is hit when the downtime increases. The profits evaporate in fines paid to the state, and federal entities regulating the energy sector. Also, profits are not being generated when power producing systems are isolated from the grid.
The last phase of the preparedness model is the Mitigation phase. By identifying the threats, vulnerabilities, and resources we are able to develop and implement mitigating factors to reduce the risk, threats, and vulnerabilities and possible eliminate them altogether. Many of the threats in the first category, which are threats inside the home, can be mitigated by utilizing age appropriate safety equipment. All power receptacles that are not in use will have hard plastic covers. All cupboards and drawers are equipped with child safety latches to prevent
Cyber Emergency Response Team (ICS-CERT) the energy sector has been a focal point for cyber-attacks.
The new communications system will be installed using the existing cabling. The connection that will be used to tie the buildings together will use fiber as a transmission medium. Each of the four buildings is tied together using previously installed multi-mode fiber optic cable. Prior to the installation of this system, this fiber was referred to as “Dark Fiber”, meaning it was not used and therefore no light was being transmitted through it. During the construction of 2 of the 4 building, Structured Cabling was installed to facilitate future communication and data requirements.
Business was also dependent upon information technology. If systems were down for some reason due to viruses or major electricity failure, the company would not be able to fill orders. The company should consider external power supply.
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.
It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security goals. Using the Defense in Depth strategy will require an understanding of the interactions between devices occuring within the network.
Most of the backup systems and security system will fail after a long periode of electricitiy blackout and it leads to complete failure. Most critical systems like hospitals, firrst responder facilities, water and sweage system, stock exchanges have backup power generation in particular place but it gives power backup for several hours or for a few days.
Malware protection is another factor to appreciate, as this vice can lead to significant losses to an organization as it corrupts available data for use. The various networks that are used by business firms should consider adhering to network design principles that uphold the security standards set in place. The organizational staff using the different accounts of the company should be limited, and very few individuals should only access the administrator database. Moreover, the various user activities should be regularly monitored and consider changing of account passwords or deleting none existing accounts (Wolden et al., 2015).
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
In the following report I will discuss the role of network management and how the network manager contributes to the network security of an organisation. Network security will be discussed in full to inform on how big of an impact network attacks can have on an organisation. Once the impact of network security has been covered I will go through all possible threats that can harm an organisation and the steps network managers should go through to secure a network to the best of their ability. The importance of network tools will be introduced last along with benefits they can provide.
