Cyber Security

GCC businesses rely on cloud platforms, connected devices, remote access, digital services, and shared business networks. This wider digital environment increases the need for strong network security across offices, branches, cloud systems, endpoints, and critical infrastructure. Network security requirements also differ across Saudi Arabia, the UAE, Bahrain, Qatar, Kuwait, and Oman. This guide explains the main technical controls, regulatory factors, access risks, monitoring practices, and practical checks that GCC businesses should consider. Why Network Security Has Become a GCC Business Requirement GCC businesses continue to expand digital operations across cloud platforms, online services, remote teams, and connected systems. Each connection creates another path that attackers can target. Businesses also face risks from stolen credentials, ransomware, vulnerable devices, unauthorised access, exposed systems, and third-party connections. Strong network security helps businesses protect operations, data, users, and essential systems. What a Secure Business Network Should Protect A secure network should cover more than office computers and internet connections. Businesses should map every system that connects to their digital environment. Office Networks: Protect internal systems, users, routers, switches, and wireless connections. Cloud Environments: Secure cloud workloads, accounts, configurations, and network access. Servers: Protect application, database, file, and infrastructure servers. Employee Devices: Secure laptops, desktops, mobile devices, and other endpoints. Remote Connections: Control access from home offices, branches, and external locations. IoT Devices: Secure cameras, sensors, smart devices, and connected equipment. OT Systems: Protect industrial control systems and operational networks from cyber threats. Third Party Connections: Control vendor, contractor, supplier, and partner access. Network Security Controls GCC Businesses Should Have in Place GCC businesses need several connected controls instead of relying on one security product. The exact control level should match the business environment, risk profile, sector, and applicable regulations. Network Segmentation Businesses should separate users, servers, guest networks, sensitive systems, and critical environments. Segmentation limits unauthorised movement when an attacker compromises one part of the network. Firewalls and Traffic Filtering Firewalls should control inbound and outbound traffic based on approved rules. Businesses should review firewall rules regularly and restrict unnecessary connections to internet-facing systems. Identity and Access Controls Businesses should use multi-factor authentication, least privilege access, role-based permissions, and privileged account controls. They should also remove inactive accounts quickly. Secure Remote Access Remote users should connect through approved secure access methods and use multi-factor authentication. Businesses should restrict remote access to authorised users, devices, systems, and services. Endpoint and Server Security Businesses should maintain device inventories, apply security patches, use endpoint protection, remove unsupported software, and monitor vulnerable systems. Encryption and Secure Communications Businesses should protect sensitive information during transmission and storage with appropriate encryption and cryptographic controls. Saudi Arabia’s NCA also publishes national cryptographic standards for protecting national data, systems, and networks. How Cloud, IoT and OT Change Network Security Requirements Modern GCC networks often include cloud services, connected devices, and operational technology. Each environment creates different security requirements and access risks. Cloud Security: Control identities, configurations, network access, workloads, and data within cloud environments. IoT Security: Track connected devices, change default credentials, update firmware, and isolate high-risk devices. OT Security: Separate operational networks from general IT environments and restrict remote access. Cloud Responsibilities: Define security responsibilities between the business and cloud provider. Device Monitoring: Monitor connected devices for unusual traffic, outdated software, and unauthorised access. Critical Systems: Apply stronger controls to systems that can cause major operational or safety impacts. Saudi Arabia’s Cloud Cybersecurity Controls extend the ECC framework to cloud service providers and cloud service tenants. NCA also maintains dedicated controls and implementation guidance for OT, critical systems, data, cloud, and telework environments. GCC Cybersecurity Requirements: What Businesses Need to Check by Market The GCC does not use one universal cybersecurity requirement for every business. Companies should identify the rules that apply to their country, sector, entity type, systems, and level of criticality. Saudi Arabia Businesses should check the National Cybersecurity Authority framework and determine which controls apply to their environment. ECC 2-2024 provides core cybersecurity controls, while NCA also publishes specialised controls for cloud, data, critical systems, OT, and other environments. United Arab Emirates UAE businesses should identify applicable federal, sector, and emirate-level requirements. The UAE Information Assurance Regulation establishes management and technical information security controls for designated critical entities, while UAE authorities also support cybersecurity monitoring, incident response, vulnerability assessment, and infrastructure protection. Bahrain Bahrain’s National Cyber Security Center publishes Baseline Cyber Security Controls covering governance, security defence, incident and log management, third party and cloud security, OT and IoT security, and audit. Businesses should assess which requirements apply to their operations. Qatar Businesses operating in Qatar should identify applicable national cybersecurity requirements and sector rules before setting their control baseline. Regulated industries may face additional obligations. Kuwait Kuwait businesses should check requirements from the relevant national and sector authorities. Financial institutions should also review the cybersecurity and operational resilience requirements that apply to their regulated activities. Oman Businesses in Oman should identify applicable information security, data protection, sector, and national cybersecurity requirements. Companies should then map their network controls against those obligations instead of assuming that another GCC country’s framework applies. Network Security for Remote Employees and Third-Party Users Remote employees and external users can create direct pathways into business networks. GCC businesses should control these connections with clear access rules. Verify Users: Require strong authentication before granting network access. Use MFA: Add another authentication layer for remote and privileged access. Restrict Vendor Access: Give suppliers access only to approved systems. Limit Access Time: Disable temporary accounts after the approved work ends. Monitor Sessions: Record relevant access activity and review unusual behaviour. Review Accounts: Remove unused employee, contractor, and vendor accounts promptly. How GCC Businesses Should Monitor and Respond to Network Threats Prevention alone cannot stop every incident. Businesses need continuous monitoring and a defined response process to identify suspicious activity and limit damage. Centralise Security Logs Collect relevant logs from firewalls, servers, endpoints, applications, and critical network devices. Monitor Network Activity Review unusual traffic, repeated login failures, unexpected connections, and other indicators of compromise. Detect and […]
