32. Figure 10-3Preparing for Security Certification Management of Information Security, 2nd ed. - Chapter 10

33. Employment Policies and Practices • The general management community of interest should integrate solid information security concepts across all of the organization’s employment policies and practices • Including information security responsibilities into every employee’s job description and subsequent performance reviews can make an entire organization take information security more seriously Management of Information Security, 2nd ed. - Chapter 10

34. Hiring • From an information security perspective, the hiring of employees is laden with potential security pitfalls • The CISO, in cooperation with the CIO and relevant information security managers, should establish a dialogue with human resources personnel so that information security considerations become part of the hiring process Management of Information Security, 2nd ed. - Chapter 10

35. Hiring Issues • Job Descriptions • Organizations that provide complete job descriptions when advertising open positions should omit the elements of the job description that describe access privileges • Interviews • In general, information security should advise human resources to limit the information provided to the candidates on the access rights of the position • When an interview includes a site visit, the tour should avoid secure and restricted sites, because the visitor could observe enough information about the operations or information security functions to represent a potential threat to the organization Management of Information Security, 2nd ed. - Chapter 10

36. Hiring Issues (continued) • New Hire Orientation • New employees should receive, as part of their orientation, an extensive information security briefing • On-the-Job Security Training • Organizations should conduct periodic security awareness and training activities to keep security at the forefront of employees’ minds and minimize employee mistakes • Security Checks • A background check should be conducted before the organization extends an offer to any candidate, regardless of job level Management of Information Security, 2nd ed. - Chapter 10

41. Security as Part of Performance Evaluation • To heighten information security awareness and change workplace behavior, organizations should incorporate information security components into employee performance evaluations • Employees pay close attention to job performance evaluations, and including information security tasks in them will motivate employees to take more care when performing these tasks Management of Information Security, 2nd ed. - Chapter 10

42. Termination Issues • When an employee leaves an organization, the following tasks must be performed: • The former employee’s access to the organization’s systems must be disabled • The former employee must return all removable media • The former employee’s hard drives must be secured • File cabinet locks must be changed • Office door locks must be changed • The former employee’s keycard access must be revoked • The former employee’s personal effects must be removed from the premises • The former employee should be escorted from the premises, once keys, keycards, and other business property have been turned over Management of Information Security, 2nd ed. - Chapter 10

43. Termination Issues (continued) • In addition to performing these tasks, many organizations conduct an exit interview to remind the employee of any contractual obligations, such as nondisclosure agreements, and to obtain feedback on the employee’s tenure in the organization • Two methods for handling employee outprocessing, depending on the employee’s reasons for leaving, are hostile and friendly departures Management of Information Security, 2nd ed. - Chapter 10

44. Hostile Departure • Security cuts off all logical and keycard access, before the employee is terminated • The employee reports for work, and is escorted into the supervisor’s office to receive the bad news • The individual is then escorted from the workplace and informed that his or her personal property will be forwarded, or is escorted to his or her office, cubicle, or personal area to collect personal effects under supervision • Once personal property has been gathered, the employee is asked to surrender all keys, keycards, and other organizational identification and access devices, PDAs, pagers, cell phones, and all remaining company property, and is then escorted from the building Management of Information Security, 2nd ed. - Chapter 10

45. Friendly Departure • The employee may have tendered notice well in advance of the actual departure date, which can make it much more difficult for security to maintain positive control over the employee’s access and information usage • Employee accounts are usually allowed to continue, with a new expiration date • The employee can come and go at will and usually collects any belongings and leaves without escort • The employee is asked to drop off all organizational property before departing. Management of Information Security, 2nd ed. - Chapter 10

46. Termination Issues • In either circumstance, the offices and information used by departing employees must be inventoried, their files stored or destroyed, and all property returned to organizational stores • It is possible that departing employees have collected and taken home information or assets that could be valuable in their future jobs • Only by scrutinizing system logs during the transition period and after the employee has departed, and sorting out authorized actions from system misuse or information theft, can the organization determine whether a breach of policy or a loss of information has occurred Management of Information Security, 2nd ed. - Chapter 10

47. Personnel Security Practices • There are various ways of monitoring and controlling employees to minimize their opportunities to misuse information • Separation of duties is used to make it difficult for an individual to violate information security and breach the confidentiality, integrity, or availability of information • Two-man control requires that two individuals review and approve each other’s work before the task is considered complete Management of Information Security, 2nd ed. - Chapter 10

48. Figure 10-6Personnel Security Controls Management of Information Security, 2nd ed. - Chapter 10

49. Personnel Security Practices • Job rotation is another control used to prevent personnel from misusing information assets • Job rotation requires that every employee be able to perform the work of at least one other employee • If that approach is not feasible, an alternative is task rotation, in which all critical tasks can be performed by multiple individuals Management of Information Security, 2nd ed. - Chapter 10

50. Personnel Security Practices (continued) • Both job rotation and task rotation ensure that no one employee is performing actions that cannot be knowledgeably reviewed by another employee • For similar reasons, each employee should be required to take a mandatory vacation, of at least one week per year • This policy gives the organization a chance to perform a detailed review of everyone’s work Management of Information Security, 2nd ed. - Chapter 10
