Types And Techniques Of Computer System Security Essay

Computers have become much more important and popular to our society in recent decades. The computer’s ability to perform so many tasks speedily and reliably makes it useful for a wide variety of purposes. Therefore much important information is stored on computers. Because people and organisations depend on computers every day for a variety of significant tasks, it is imperative that the systems which are used are protected from loss, damage and misuse. This essay identifies some potential risks to computer systems and software and the safeguards that can be taken to minimise these risks. A computer security risk is defined as any event or action that could cause a loss or damage to computer equipment, software, data and information, or

The framework of security policy is defined to construct a structure by the help of which policy gaps can be identified in an easy manner. A system specific policy would assist to ensure that all employees and management comply with the policies. This is also used to maintain the confidentiality for user authentication would assist in the confidentiality aspect of security, maintain integrity (There are several limiting rules or constraints which are distinct in the relational data model and whose work is to maintain the data’s accuracy and maintain its integrity.), availability and authenticity of the system. Access controls are a collection of mechanisms that work together to create security architecture to protect the assets of an information system. One of the goals of access control is personal accountability, which is the mechanism that proves someone performed a computer activity at a specific point in time. So, the framework acts as the guideline

Organizations of all sizes face numerous compliance challenges around data privacy and IT security management. Many future computer systems will be faced with the possibility of external threats. Unless a system is entirely self-contained, any external digital interface represents an opportunity for an adversary to attack the system. Risk mitigation centers on proactively building controls, such as authentication and intrusion prevention systems, to prevent or minimize potential threats and impact.

The purpose of each control on the Sphere of Protection is to protect the valuable information and information systems assets. The focus of each control is management, operational, and technical controls in which sums up the sphere of protection.  Management controls cover security processes designed by strategic planners and performed by security administration (2) Operational controls deal with operational functionality of security in organization and (3) Lastly, technical controls address tactical and technical implementations related to designing and implementing security in

To establish a framework to maintain the security, integrity and availability of ABC 's information assets

Security is the degree of resistance to, or protection from, harm. It applies to any asset, such as a person, dwelling, community, item, nation, or organization. Information held on your IT systems is vitally important. Its availability, integrity and confidentiality may be critical for the continued success of your business. Security can be breached in several ways, e.g. by system failure, theft, inappropriate usage, unauthorised access or computer viruses. This will lead to the loss of sensitive or critical information, directly affect your competitiveness and cash flow, also damage your reputation.

Information is the most valuable commodity that individuals and global corporations use to grow financially, economically, and independently. The protection and security of the information is essential. One of the most vital foundations of protection information is the authentication process. The authentication process is utilized to protect computer and network systems against various types of security threats, such as password-cracking tools, password dictionary attacks, mistreatment of user access rights, and any potential unauthorized attacked. Understanding how to authenticate users and the accessible information that is readily available on system networks can help prevent future issues as well as provide insight into the developmental process for new systems. In addition, authentication is simply determining whether someone or some machine is, in fact, who or what they declared there to be. This process directly reflects on and correlates to the readiness and ease of access to information and the protection of it.

Advanced Research is a growing company in the medical research field and has made a great impact due to its recent success with research and development regarding pharmaceuticals. Due to its large successes and quick growth, Advanced Research has also developed into an attractive target for cyber criminals and attackers. This has been previously demonstrated by the defacement of Advanced Research’s public facing website as well as being a victim of Denial of Service attacks throughout a nine-month period in 2011.

The Oxford American Dictionary of Current English defines admonition as “to reprove. Urge. Give earnest advice to. Warn”. Understanding this how do we employ admonitions systems to information technology to make it more useful in-regards to Network and system security? Using admonition software we are attempting to create an environment that will either prevent data from being in-advertently distributed across networks. Act as a deterrent to those trying to access the network illegally. Or warning users of the potential harm their actions may cause. In developing an IT security strategy,

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

The correct configuration of security technologies is mandatory to balance the need for access and safety of information (Cavusoglu & Raghunathan, 2009). Many companies use the layered approach to ensure protection of their network information system (Cavusoglu & Raghunathan, 2009). By using this approach, many security technologies rely on each other to operate effectively (Cavusoglu & Raghunathan, 2009). Three technologies commonly used together are Intrusion Detection Systems, Intrusion Prevention Systems, and firewalls. When configured properly, these technologies complement each other (Cavusoglu & Raghunathan, 2009).

An important consideration of an information or operating system of a business or organization is to have a security system that protects information, data, and integrity of the company’s sensitive information and records. If a business or company does not have adequate security, financial, sensitive, and classified information may be compromised and prone to possible viruses and malware, hacking, or at risk of a cyber-attack to the company’s data resulting in possible

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

A threat agent is the facilitator of an attack however; a threat is a constant danger to an asset.
