It affects every company’s operation, reputation and ultimately impacts revenue, profits, and a competitive edge. Yet many companies do not implement defenses that could help to prevent and control data breaches. In June 2012 LinkedIn a business social network site was hacked, this data breach was discovered when IT security experts discovered millions of LinkedIn passwords on a Russian underground site. The reason this happened was that the company was using outdated encryption methods and within 2 days, most passwords were cracked. What steps can a business take to keep control of its data security? What security management processes and activities in each process should a business follow to ensure they have an Information Technology Risk management strategy in place?

- Computer Security is one of the fastest-moving fields in the world today. There are generally several incidents each week, including data breaches, large scale attacks, or some advancement in security research (i.e. new tools, techniques, vulnerabilities, or exploits). Select a recent event from your favorite security news source and summarize it. Include your source and an analysis of the event, including a summary of what happened, any new information from the event that changes current security practice, and any larger scale implications from the event. Relate the event to the topics in Chapter 1 of the book, namely the CIA triad, U.S. Compliance Laws (if any), IT domains, security policy, and/or data classification. In addition, relate the event to a biblical example.A security policy is a document that provides employees with clear instructions about acceptable use of company confidential information, explains how the company secures data resources and what it expects of the people who work with this information. Most importantly, the policy is designed with enough flexibility to be amended when necessary. You are working in organization X, and you are supposed to develop an issue-specific security policy issue is MOBILE COMPUTING To develop the different sections of your policy, you can refer to SANS Policy Templates https://www.sans.org/information-security-policy/Explore encrypted communication and cryptography attacks
