Security threats are constantly evolving, and compliance requirements are becoming increasingly complex. Organizations must create a comprehensive information security policy to cover both challenges. An information security policy makes it possible to coordinate and enforce a security program and communicate security measures to third parties and external auditors. Show To be effective, an information security policy should:
The importance of an information security policyInformation security policies can have the following benefits for an organization:
12 Elements of an Information Security PolicyA security policy can be as broad as you want it to be, from everything related to IT security and the security of related physical assets, but enforceable in its full scope. The following list offers some important considerations when developing an information security policy. 1. PurposeFirst state the purpose of the policy, which may be to:
2. AudienceDefine the audience to whom the information security policy applies. You may also specify which audiences are out of the scope of the policy (for example, staff in another business unit which manages security separately may not be in the scope of the policy). Guide your management team to agree on well-defined objectives for strategy and security. Information security focuses on three main objectives:
5. Data classificationThe policy should classify data into categories, which may include “top secret,” “secret,” “confidential,” and “public.” The objectives for classifying data are:
6. Data support and operations
7. Security awareness and behaviorShare IT security policies with your staff. Conduct training sessions to inform employees of your security procedures and mechanisms, including data protection measures, access protection measures, and sensitive data classification.
8. Encryption policyEncryption involves encoding data to keep it inaccessible to or hidden from unauthorized parties. It helps protect data stored at rest and in transit between locations and ensure that sensitive, private, and proprietary data remains private. It can also improve the security of client-server communication. An encryption policy helps organizations define:
9. Data backup policyA data backup policy defines rules and procedures for making backup copies of data. It is an integral component of overall data protection, business continuity, and disaster recovery strategy. Here are key functions of a data backup policy:
10. Responsibilities, rights, and duties of personnelAppoint staff to carry out user access reviews, education, change management, incident management, implementation, and periodic updates of the security policy. Responsibilities should be clearly defined as part of the security policy. 11. System hardening benchmarksThe information security policy should reference security benchmarks the organization will use to harden mission-critical systems, such as the Center for Information Security (CIS) benchmarks for Linux, Windows Server, AWS, and Kubernetes. 12. References to regulations and compliance standardsThe information security policy should reference regulations and compliance standards that impact the organization, such as the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), Payment Card Industry Data Security Standard (PCI DSS), the Sarbanes-Oxley Act (SOX), and the Health Insurance Portability and Accountability Act (HIPAA). 9 best practices for successful information security policies
