Setting file permissions is a form of DAC because it is the owner’s discretion. Configuring as many security layers as the user can will ensure the server will stay secure. Not all OS are 100% secure, but they can be configured to make it very hard for a hacker to
We can judge the network to be secured if there are proper security measures implemented to protect the network. In order to be competent and secured, it is necessary to be aware of different security features. Some of the basic features/elements of security are: • Confidentiality • Integrity • Availability or Non-Repudiation These three put together are commonly known as “CIA” (Confidentiality, Integrity, and Authenticity) in the domain of network security. Some of the benefits of CIA are mentioned as follows: • Comprehensive security monitoring features • Integrated security management of critical assets on the network • Flexible in terms of providing the necessary security features to varied networks In this chapter you will learn about
These are (Virtual Private Network) VPN Policy, Password Policy and Acceptable Use Policy. Acceptable Use Policy is a policy that outlines the acceptable use of computer equipment. This policy is in place to protect employees in regards to inappropriate use. Any case of inappropriate use can expose the network to several risks, including viruses. Passwords are the frontline of protection of user accounts.
Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure data transmission over the network. But to achieve complete data security is a challenging issue of data communication.
These methods are not only good in practice in one’s personal life, but also in one’s professional life as many companies and government agencies have policies regarding use of information technology resources and the retention of personally identifiable information. The most important protection for personally identifiable information is a person’s knowledge of the type of threats and risks there are to their information. For example, the ability to identify a phishing attempt will keep a person from providing information that may compromise their data. Companies in communications with their customers specifically state they will never request a customer’s password. If someone does request this under the guise of being a part of that company, this is a red flag and the customer or user should not provide the information and immediately seek out the company to alert them of phishing attempts.
Database security concerns the use of a broad range of information security controls to protect databases (potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links) against compromises of their confidentiality, integrity and availability. It involves various types or categories of controls, such as technical, procedural/administrative and physical. Database security is a specialist topic within the broader realms of computer security, information security and risk management. Security risks to database systems include, for example: Unauthorized or unintended activity or misuse by authorized database users, database administrators, or network/systems managers, or by unauthorized users or hackers (e.g. inappropriate access to sensitive data, metadata or functions within databases, or inappropriate changes to the database programs, structures or security configurations); Malware infections causing incidents such as unauthorized access, leakage or disclosure of personal or proprietary
David Anderson should assist Henry Jones in becoming fully aware of policies and procedures of the company. This would help Henry understand that what he is doing is causing a major security concern and by typing in his username and password he is acting in the public interest. Since this is not the first time Henry has done this and we know that he will probably be terminated for this, section 6.08 helps us decide what we should do next. It is David’s responsibility to report any errors in the software upon which he works. He has found a major security risk and it is now his responsibly to report it to the company.
Cyber Security a subset of Information Security. Cyber Security is the ability to use resources and policies to protect the use of cyberspace from cyber-attacks. Information Security on the other hand, is the protection of information that is either, printed or written, stored electronically from unauthorized access, use, or destruction in order to provide confidentiality, integrity, and availability (CIA). "The international standard, ISO/IEC 27002 (2005), defines in- formation security as the preservation of the confidentiality, integrity and availability of information (von Solms, R., & van Niekerk, J. 2013, as cited in ISO/IEC 27002, 2005, p. 1).
Cyber-attacks are attacks on a target system carried about by different people and may not be associated with a terrorist group. They may be trying to steal information or corrupt data. There are many ways to carry out cyber-attacks such as malware, botnets, viruses, denial of service (DoS) accounts and many other types of attacks. Cybersecurity is also known as information security which applies to devices such as computers, laptops, mobile devices, networks, and including the internet to include preventing unauthorized access, modify, or destroying data. Department of Homeland Security plays roles in securing the federal government and helping to secure a cyber-ecosystem by helping with investigations and arrest of cyber criminals, releasing cyber alerts about threats, and educate the public and stay safe online.
Chapter 2 Security and Encryption Introduction the process of preventing and detecting unauthorized using of your computer is called Computer security, prevention help to stop unauthorized users (also known as "intruder") from accessing computer system, detection determine where if someone attempted to break into system or not. Network security is the proper safeguarding of all components associated with a network. Security involves the various measures to protect network's components and resource from various threats including physical (e.g., natural disaster, sabotage) and illegitimate users. In generally, security is similar to safety, Security is the condition of being protected against danger and loss . Security issues associated with co-operative routing in multi-hop wireless networks they are as follows : • Confidentiality: The confidentiality property refers to limiting unauthorized access to sensitive information.
