Silver Star Mines risk assessment illustrates how a company can be at great danger if proper security measures and policies are not put in effect on every business process. In fact, “an IT security risk assessment is needed for each asset in the organization that requires protection” (Stallings, 2015, p. 486). According to the initial review, Silver Star Mines risk assessment highlights the following risk areas: Supervisory Control and Data Acquisition (SCADA) at top critical risk, stored information at extreme risk, financial, procurement, production systems at high risk and e-mail services at high risks accordingly. With this in mind, management should evaluate and take proper security measures to assets that need the most protection, assets …show more content…
530). The risks assessment suggests to identify and manage critical documents and store them on a centralized application and file servers. Moreover, it proposes to use applicable controls. To further explain the applicable controls, role based control (RBAC) should be enabled to regulate access to the files resources based on the roles of individual users within the company. In this structure, access is the ability of an individual user to perform a specific task, such as view, create, or modify a file. Roles are defined according to job proficiency, authority, and responsibility within the business. In fact, role describes the level of access that users have for their account. For example, by assigning roles to users, administrators can allow multiple users to complete tasks securely. Also, RBAC limits risk by ensuring that users do not have access beyond their training or level of control. Thus, an employee 's role determines the level of permissions granted and ensures that junior level employees are not able to access sensitive information or perform high level tasks. Additionally, an employee education and security awareness program should be implemented to improve employee behavior, hold employees accountable for their actions, complying with rules, and improve employee knowledge base on …show more content…
Likewise, the report suggests to implement a contingency planning and perform a backup on the e-mail service. Equally important, UTM deployment “systems can provide an organization with a defense in depth using multiple layers of filters and defense mechanisms to thwart attacks. One methodology to reducing the administrative and performance problem is to replace all inline network products (firewall, IPS, IDS, VPN, anti spam, antispyware, and so on) with a single device that integrates a variety of approaches to dealing with network-based attacks.” (Stallings, 2015, p. 326). Indeed, UTMs offer great protection advantages such as IDS/IPS, antimalware, anti spam and content filtering in a single, easy to manage appliance. More recently UTMs have added features, like load balancing, VPN and data loss prevention (DLP), and are progressively delivered as a service via the cloud. Again, employee security training on e-mail risks and development of policies are critical to the prevention of risks associated with spam email, worms, exploits, etc. Additional services can be implemented such as SaaS Endpoint protection to defend against email threats by scanning messages before they reach the network, and by blocking or quarantining detections
The case study The Blast in Centralia no. 5: A mine Disaster No One Stopped is a useful lens through which to identify potential pitfalls for national security organizations. The most powerful lessons that ought to be learned by the case study are twofold. First, political interference in the work of governmental organizations can lead to dysfunction and mission failure. Second, the failure to conduct independent oversight over a governmental organization—especially when its performance has been openly questioned—permits that dysfunction to continue unabated.
The tar creek mining site originally was owned by a Native American tribe, the Quapaw. The Quapaw wanted to keep these lands, but the Bureau of Indian Affairs deemed members opposing a transaction to mining companies “incompetent” (1). In such a case the business could continue and the Bureau of Indian Affairs sold the lands to mining companies. In essence these lands were stolen from the Quapaw because they were ripe for mining. These mines were then used from approximately 1891 to 1970. In the 79 years the mines were open 1.7 million metric tons (~3.75 billion pounds) of lead and 8.8 million metric tons (~19.4 billion pounds) of zinc were withdrawn from the mine (2). The entire area around Tar Creek is known as the tri-state mining area. This tri-state area was a massive source of metals. This area accounted for 35% of the all worldwide metal for a decade. It also provided the majority of metals the United States used in World wars I and II (3).
In order to protect the application servers from the internet, the most common un-trusted network, the proposal suggests a firewall to be installed between the internal network and external router. The firewall would be an Adaptive Security Appliance (ASA) firewall, "the ASA is not just a pure hardware firewall. In brief, the Cisco ASA is a security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities. It provides proactive
Email security services will include blocking ransomware and emerging threats with the highest effectiveness and accuracy, stopping new and sophisticated threats such as ransomware, spear phishing, and business email compromise. Spear phishing will be prevented by having a comprehensive defense that includes multiple layers of protection, strong isolation , deep visibility and dynamic security awareness. Attacks will be contained and responses will be orchestrated across endpoint security and web gateways by remediating attacks and blacklisting threats. Dynamically classify impostor email and other threats that don't involve malware. Sender-recipient relationship, domain reputation, email headers, envelope attributes and email content will be analyzed. Custom rules will be integrated allowing group and user level controls to meet the needs of the client. Quarantines will enable the customer to separate email
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 decision to monitor e-mail is left to the organization that provides the e-mail service to users. These organizations can range from educational institutions and private corporations, to governments and non-profit organizations. Each of these different types of organizations has a different agenda and goals, not only in general, but also for their members-and more specifically, for their members' e-mail. While educational institutions can provide e-mail facilities to their constituents for the purposes of convenience, employers almost always maintain e-mail facilities for the sole purpose of improving the on-the-job productivity of their employees.
Following compliance guide line provided by NIST SP 800-16 that describes security and training requirements is another way to boost the awareness of the employees. These kind of training and follow of compliance emphasize on roles rather than fixed content providing flexibility, adaptability, and longevity. Furthermore varying method of training with respect to different users is also beneficial. For example training for general users, training for managerial users and training for technical users which can be categorized by job category or job functions.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
The term “be prepared” applies especially well to today’s business environment, where enterprises across all industries and locations are challenged by a volatile, increasingly unpredictable world. In addition to protecting their internal resources, organizations must consider the security and well-being of their employees, partners, suppliers and customers, as well as the reliability of the web of networks and systems on which most now depend.
capacity and performance. However, as networks enable more and more applications and are available to more and more users, they become ever more vulnerable to a wider range of security threats. To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks.
New technologies are allowing us to do things faster, easier, and more efficiently than ever before. Almost every new innovation in technology improves the speed and productivity of any task at hand. Electronic mail (E-mail) is possibly one of the greatest things to happen to the world. Despite this, there are people who find difficulties in using either E-mail or conventional mail. To help decide whether to use E-mail or the United States postal Service, a comparison of each one’s speed, ease of use, reliability, and cost is a helping factor.
This report aim to explain how is achieved risk control through strategies and through security management of information.
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
The network management plan and security plan is important to help the company figure out how they will improve its network and security procedures for the company. Planning involves outlining objectiv...
A hazard is a potential damage, adverse health or harm that may effects something or someone at any conditions. Other than that, the risk may be high or low, that somebody could be harmed depending on the hazards. Risk assessment is a practice that helps to improve higher quality of the develop process and manufacturing process. It is also a step to examine the failure modes of the product in order to achieve higher standard of safety and product reliability. Unfortunately, it is common that a product safety risk assessments are not undertaken, or not carried out effectively by manufacturer. Mostly an unsafe and unreliable product was produced and launched on to the market. Thus, the safety problems are mostly identified after an accident happened or after manufacturing problems arisen. In order to prevent risk, a person should take enough precautions or should do more to prevent them because as a user should be protected from harm that usually caused by a failure for whom did not take reasonable control measures.
