Comprehensive security is the key to any organization. There are three categories of security controls that businesses must consider: management security, operational security, and physical security. Each type is important for overall security and to protect against threats.
What is Management Security?
Management security is the overall design and governance of your security controls, sometimes known as administrative controls which are the rules in your security environment.
Policies and Procedures
To create a secure business environment you need to define the rules and guidelines for your security practices. Your policies and procedures will cover areas such as access control, incident response, and risk management. These guidelines give your employees a clear documented framework to follow, so everyone follows the security practices across the organization in the same way.
Risk Assessment and Security Management
Risk assessments look at your business risks, determines the impact of those risks and implements fixes which is a key part of security management. This proactive approach helps you allocate resources efficiently and strengthen your overall security.
Security Awareness and Employee Training
Your employees need to understand the business policies for your security program and how they can help keep a secure environment. Security awareness and training programs will help them learn best practices and what steps they need to take to stay security aware. This way your business can reduce human error and strengthen your overall security.
Compliance and Auditing
Successful security programs require your business to regularly review your security policies and regulatory requirements. Compliance and auditing helps your business follow security controls and meet industry standards. Continually monitoring helps you spot areas that need improving and keeps you up-to-date with current security regulations.
Example
An organization requires that passwords need to change every 90 days in their security policy. This policy is part of the overall security framework for the business and helps increase their security by reducing the risk of unauthorized access. Frequent password changes make it harder for attackers to exploit compromised credentials, so it strengthens their overall security.
What is Operational Security?
Operational Security is the effectiveness of your controls. Sometimes referred to as technical controls, these are access controls, authentication, and security topologies applied to networks, systems, and applications. Operational security is key to ensuring the technical controls you have in place are effective at protecting against threats.
Access Controls
Using access controls will limit who can use your system, applications and data within the business. These controls make sure only approved people see your sensitive information.
Authentication Mechanisms
Passwords and multi-factor authentication (MFA) are types of authentication methods that can help your company add an additional level of security. Using more than one form of identification, MFA reduces risk and makes sure only approved users can get into your protected systems and data.
Network Security
Network security uses firewalls, intrusion detection and prevention systems (IDS/IPS) to block cyber attacks and unauthorized access. By having strong network security, organizations can find and stop intrusions and keep their data safe and private.
Encryption
When data is being sent outside your business or just being stored, you need encryption to keep it safe. Encryption will change the data into a secret format so if someone gets access they can’t read it. Using strong encryption helps you protect data from theft and misuse.
Example
A Role-Based Access Control (RBAC) is a key allowing access to different parts of a system depending on a person’s position in your company. This limits access and simplifies user permissions making it easier to manage who can see what which helps increase security.
What is Physical Security?
Physical security is the set of measures to protect business assets, such as personnel, data and hardware from physical threats that could harm, damage, or disrupt your business. It includes security measures such as surveillance, access control, environmental controls, and contingency planning. Physical security is key to maintain confidentiality, integrity and availability of systems and data and business continuity in the face of unexpected events.
Access Control Systems
Access control systems are critical to limit access to buildings or specific areas within an organization. These systems make sure only the right people can enter secure places. They help protect physical assets and people from dangers. Good access control systems keep these important areas secure.
Surveillance Systems
Surveillance systems, such as closed-circuit television (CCTV), are critical to monitor and record activities within an organization. These systems watch and records unauthorized activities and strange behavior giving valuable evidence that can show what happened if something goes wrong.
Environmental Controls
Environmental controls are key to maintaining the optimal conditions for sensitive equipment and data. These controls regulate temperature, humidity, and fire suppression systems to protect physical assets from environmental hazards.
Contingency Planning
Developing a disaster recovery and business continuity plan to make sure your business can continue in cases of disruption is what contingency planning is all about. These plans should outline the steps you need to take to recover from natural disasters, equipment failures or cyber attack incidents. When you are ready for emergencies, your business will have less downtime and keep important services running.
Example
A practical example of a physical security control is biometric access controls. These systems use unique biological characteristics such as fingerprints or facial recognition to prevent unauthorized access to a data center. Using biometric access controls can provide you with high security because only authorized people will be able to access sensitive areas and this protects your important information and systems.
