Information Security Planning Planning reduces the likelihood that the organization will be reactionary toward the security needs. Security planning involves developing security policies and implementing controls to prevent computer risks from becoming reality. The risk assessment provides a baseline for implementing security plans to protect assets against various threats.

Hierarchy of Security Planning Strategic Planning (3-5 years). Strategic plans are aligned with the strategic business and IT goals. They provide the vision for projects to achieve the business objectives. The plans should be reviewed annually or whenever major change to the business occur. Tactical Planning (6-18 months). Tactical plans provide the broad initiatives to support and achieve the goals specified in the strategic plans. Operational and Project Planning. Specific plans with milestones, dates and accountabilities provide the communication and direction to ensure that the individual projects are completed.

Type of Security Planning Proactive Planning: Develop security policies and controls. Implement tools and techniques to aid in security. - Secure access, secure data, and secure code. - Techniques for network security – firewall, VPN. - Detection tools. Implement technologies to keep the system running in the event of a failure. Reactive Planning: Develop a contingency plan.

Security Organization Best Practice Job rotation. Job rotation reduce the risk of collusion of activities between individuals. Separation of duties. One individual should not have the capability to execute all of the Steps of a particular process. Least privilege (need to know). Granting users only the accesses that are required to perform their job functions. Mandatory vacations. Requiring mandatory vacations of a specified consecutive-day period. Job position sensitivity. The access and duties of an individual for a particular department should be assess to determine the sensitivity of the position.

Separation of Duties The same individual should not typically perform the following functions: Systems administration Network management Data entry Computer operations Security administration Systems development and maintenance Security auditing Information systems management Change management

Personnel Security – Hiring Practices Managing the people aspect of security, from pre employment to post employment, is critical to ensure trustworthy, competent resources are employed to further the business objectives that will protect the company information. Developing job descriptions. Developing confidentiality agreements. Contacting references – Reference checks. Screening/investigating background. Ongoing supervision and periodic performance reviews. Determining policies on vendor, contractor, consultant and temporary staff access. Employee terminations need different levels of care.

Background Checks Background checks can uncover the following problems: Gaps in employment. Misrepresentation of job titles. Job duties. Salary. Reasons for leaving a job. Validity and status of professional certification. Education verification and degrees obtained. Credit history. Driving records. Criminal history. Personal references. Social security number verification

Special Types of Background Checks Individuals involved in technology. Individuals with access to confidential or sensitive information. Employees with access to company proprietary or competitive data. Positions working with accounts payable, receivables, or payroll. Positions dealing directly with the public. Employees working for healthcare industry-based organizations or organizations dealing with financial information. Positions involving driving a motor vehicle. Employees who will come in contact with children.

The IT Security Learning Continuum Manage Acquire Design & Develop Implement & Operate Review & Evaluate Use Security Basics & Literacy Security Awareness (NIST, SP 800-100)

Security Awareness Provide the understanding of the importance of security within an organization. Inform employees about their roles, and expectations surrounding their roles, in the observance of information security requirements. Provide guidance surrounding the performance of particular security or risk management function, as well as provide information surrounding the security or risk management functions in general. Educate users in the fulfillment of its security program objectives, which may also include audit objectives for organizations that are bound by regulatory compliance (e.g., HIPPA, the Sarbanes-Oxley Act).

Topics for Security Awareness Corporate security policies. Organization’s security program. Regulatory compliance requirements. Social engineering. Business continuity. Disaster recovery. Emergency management. Security incidence response. Data classification. Information labeling and handling. Personnel security, safety and soundness. Physical security. Appropriate computing resource use. Proper care and handling of security credentials Risk assessment. Accidents, errors or omissions.

Awareness Activities and Methods Formalized courses, face-to-face or online. Use of posters to call attention to aspects of security. Conduct business units walk-through. Use intranet to post security reminders or host security column. Appointment of security awareness mentors. Sponsor a security awareness day. Sponsor an event with an external partner. Provide trinkets for users that support security principles. Provide security management videos, books, web sites, and collateral for references.
