What is a security policy?A security policy is a document that states in writing how a company plans to protect its physical and information technology (IT) assets. Security policies are living documents that are continuously updated and changing as technologies, vulnerabilities and security requirements change. Show
A company's security policy may include an acceptable use policy. These describe how the company plans to educate its employees about protecting the company's assets. They also include an explanation of how security measurements will be carried out and enforced, and a procedure for evaluating the effectiveness of the policy to ensure that necessary corrections are made. Why are security policies important?Security policies are important because they protect an organizations' assets, both physical and digital. They identify all company assets and all threats to those assets. Physical security policies are aimed at protecting a company's physical assets, such as buildings and equipment, including computers and other IT equipment. Data security policies protect intellectual property from costly events, like data breaches and data leaks. Physical security policiesPhysical security policies protect all physical assets in an organization, including buildings, vehicles, inventory and machines. These assets include IT equipment, such as servers, computers and hard drives. Protecting IT physical assets is particularly important because the physical devices contain company data. If a physical IT asset is compromised, the information it contains and handles is at risk. In this way, information security policies are dependent on physical security policies to keep company data safe. Physical security policies include the following information:
Security guards, entry gates, and door and window locks are all used to protect physical assets. Other, more high-tech methods are also used to keep physical assets safe. For example, a biometric verification system can limit access to a server room. Anyone accessing the room would use a fingerprint scanner to verify they are authorized to enter. Information security policiesThese policies provide the following advantages. Protect valuable assets. These policies help ensure the confidentiality, integrity and availability -- known as the CIA triad -- of data. They are often used to protect sensitive customer data and personally identifiable information.
Guard reputations. Data breaches and other information security incidents can negatively affect an organization's reputation. Ensure compliance with legal and regulatory requirements. Many legal requirements and regulations are aimed at security sensitive information. For example, Payment Card Industry Data Security Standard dictates how organizations handle consumer payment card information. Health Insurance Portability and Accountability Act details how companies handle protected health information. Violating these regulations can be costly. Dictate the role of employees. Every employee generates information that may pose a security risk. Security policies provide guidance on the conduct required to protect data and intellectual property.Identify third-party vulnerabilities. Some vulnerabilities stem from interactions with other organizations that may have different security standards. Security policies help identify these potential security gaps. Types of security policiesSecurity policy types can be divided into three types based on the scope and purpose of the policy:
Key elements in a security policySome of the key elements of an organizational information security policy include the following:
What to consider when creating a security policySecurity professionals must consider a range of areas when drafting a security policy. They include the following:
The takeawayData is one of an IT organization's most important assets. It is always being generated and transmitted over an organization's network, and it can be exposed in countless ways. A security policy guides an organization's strategy for protecting data and other assets. It is up to security leaders -- like chief information security officers -- to ensure employees follow the security policies to keep company assets safe. Failing to do so can result in the following:
