B. Strategies to Defend ICS: Apart from penetration tests there are several strategies that ICS can implement to reduce the vulnerability and make the system. (“Seven steps to effectively defend ICS,” n.d.) Below are the strategies:
1. Implementation of Application Whitelisting (AWL): Detecting ICS cyber-attack is difficult; hence we need Application Whitelisting (AWL). In one of the cyber-attack a malware having 0 percent detection rate compromised 80 percent of the assets of ICS, the antivirus seemed to be not useful in this case. Use of AWL becomes essential since it detects and prevents malware executions. Successful AWL implementation are very few. Systems such as human-machine interface (HMI) computers and database servers, are ideal candidates to run AWL. Operators and vendors must

The need to provide trusted storage and exe-cution for high-security applications have led to the evolution of HSMs. HSMs are:
Purpose-built highly secure appliances or stand-alone processors that implement trusted storage.
Buffer overflow resistant.
Trusted Execution Environment (TEE)
HSMs are most commonly used in encryption applications, for secure key generation, trust-ed encryption/decryption and secure certificate operations in certificate authorities used to generate and manage public-key certificates. (Prescatore, September 2015).
5. Authentication management: ICS can follow distributed or centralized approach.
Distributed access management: In Small ICS organizations, each system can use separate set of user credentials, accounts and roles.
Centralized account management: Large ICS organizations require central authentication systems since managing each system is not possible. These organizations should enforce the below
The Operating System (OS) is the heart of computer server and client systems; therefore they are the pivotal components of the Information Technology (IT) architecture. The OS contains the crucial data, information, and applications, which are vulnerable, and can be infiltrated to cripple the entire IT architecture of the organization. Therefore, it becomes mandatory to properly safeguard the OS from an internal or external intrusion (Stallings & Brown, 2012). This critical thinking report will highlight the security concerns that may impact the OS. Further, the security guidelines and best practices for the OS in general, along with the specific fundamentals regarding the Windows and Linux OS are comprehensively illustrated.
The HBWC business objectives should be included in the Information Security Management System (ISMS) as this document will represent the organizations approach in designing, implementing, and auditing the company 's information system security objectives. In order for the ISMS to be applicable and appropriate to the organization, an examination of the business objectives of the company is required. This step is necessary to understand the needs to the organization when designing these objectives.
These warnings can help users alter their installation’s defensive posture to increase resistance to future attacks. An intrusion detection system is comparable to a burglar alarm system. The car locks to protect the vehicle from theft. In the event someone compromises the lock, the burglar alarm detects this compromise and alarms the owner.
Identity Management & Authorization is the ability to insure the person accessing the system is one, who they say they are, and two, authorized to access that program. In addition, this means terminating user account that are no longer authorized to access the system.
Security architecture is a major component and part of a system’s architecture and is usually designed to provide important guidance during the development of the system. It usually outlines the assurance level required and in the process outlines the possible impacts that this level of security might have on the development process of the actual system. Since security is a major component for the success of any given business unit, it is necessary to have a fully functional and operative security system that meets all the necessary requirements for any organization. Some leading business firms are usually faced with the task of achieving and maintaining high security measures and methods. SecureTek one of the leading provider of security solutions is faced with the challenge of redesigning their security architecture to assure security to the data and the other firm’s valuable assets as well as ensuring security to their customers and employees who encounter risky situations when visiting this business unit.
Critical infrastructure protection (CIP) is a concept that relates to the preparedness and response to serious incidents that involve the critical infrastructure of a region or nation. Eliminating threats is impossible, so protecting against them without disrupting business innovation and growth is a
For an in-depth defence approach, case study provides a series of things that describe about what is working nowadays for a secure data.
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.

The Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) is taking the effort to reduce the risks related to all critical infrastructure for different industries. It coordinates control systems-related security incidents and information sharing between the critical infrastructure stake holders such as federal, state, local, and tribal governments and control systems owners, operators, and vendors.
In regards to business practices, incentives are common tool used in negotiations. With that being said, Intel, a technology conglomerate, gave huge incentives to its customers for using computer-chip. Many would argue that Intel was wrong, while others would say Intel business practices were fair game. Below is a detailed report, discussing Intel actions.
One type of Intrusion detection prevention system is the network-based system. This kind of system is located on a computer or appliance that is connected to the organizations net...

The usage of information systems within daily business and personal affairs for the transmission of confidential or even personal identifiable information, requires the usage of such as cryptography technology to secure the information. Three major forms of cryptography for digital transmission and data storage are hybrid, asymmetric, and symmetric cryptography algorithms, that provide security to protect the integrity, confidentiality, reliability, and authenticity of data transmissions and storage. (Rouse, 2008) However, each technology possesses individual traits and characteristics best suited for types of data transmission and storage. As symmetric key uses two identical keys for transmission and decryption, asymmetric employs a private
