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 …show more content…
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.
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.
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.
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.
Software companies are faced with external security threats from hackers and others, along with a variety of even more threatening internal security threats, like corporate spies. This has resulted in companies being more vigilant thus implementing necessary precautions to prevent unauthorized access to the pool of data within the company. These precautions include access management (access control) as well as access technology (biometrics). Industries around the world have agreed that strong access control, biometrics and security practices should be the cornerstone of every security strategy. So I will be going over the basics and each type of access control and biometrics and then I will supplement a recommendation that will provide the best security for the software company.
For an in-depth defence approach, case study provides a series of things that describe about what is working nowadays for a secure data.

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.
Throughout the world computer networks are becoming more popular as more and more technology is being implemented into organizations in order to help employees process their work, and communicate with one another. Along with the ever growing technology the more possibilities of data and information getting stolen or lost by hackers attempting to access the networks in an organization. There are many systems out there that will help detect and alert an organization of the attacks or prevent attacks from happening. Systems known as intrusion detection systems (IDSs) and intrusion preventative systems (IPSs) do exactly that for an organization and when they are combined are known as Intrusion detection and prevention systems (IDPSs).
“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.

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

Protection is achieved by a combination of technical and non-technical safeguards. For example for large enterprises there is a major task with a layered series of safeguards such as physical security measures, organizational measures, security procedures, background checks, user identifiers, passwords, smart cards, biometrics and firewalls (Spafford, 2007). In the ever-changing technological environment, security that is state-of-the-art today may be obsolete tomorrow. Therefore, security protection must keep pace with these changes. Boritz (2011), states that information security has got three principles that is confidentiality, integrity, availability (CIA). He further states that the CIA principles should guide people about their perception of information security and that a security breach needs not to be a malicious act; it could be as innocent and simple as a power outage or a failure to set network access privileges correctly, or it could be the total loss of all your facilities through a disastrous event, natural or
