Data Security

  Physical Security Threats Faced by Organizations Physical security involves protecting an organization personnel, assets, and facilities from physical threats such as unauthorized access, theft, vandalism, insider threats and environmental hazards. It is a critical aspect of overall security because it helps prevent harm or loss that could disrupt operations, compromise sensitive information, or endanger lives.   Protective Measures Customizing security measures based on the organization's scale and needs is essential. Large companies like Plagonia can afford sophisticated systems, while smaller ones like Magic Memories might opt for cost-effective yet robust solutions. Large Company Perimeter Access Control ·        Single point of entry: Centralizing entry for both vehicles and pedestrians reduces vulnerabilities. ·        Visitor Card: A system that issues visitor cards combined with guards who ...

  Mitigating damage after a data breach Data breach refers to the unauthorized access or exposure of sensitive information, typically resulting from a cyberattack or a security failure. It occurs when malicious actors exploit vulnerabilities in an organization’s systems, networks, or devices to steal, manipulate, or expose confidential data. Mitigate damages after a data breach requires a combination of technical, non-technical, and legal approaches to minimize harm, restore operations, and comply with legislation. Technical solutions to contain and prevent further compromises: ·          Isolated affected systems from the network to prevent any ongoing data exfiltration and data loss. ·          A forensic investigation should follow, preserving logs and creating digital forensic copies of affected systems for analysis. ·          Reset passwords and ...

Hardware security   In workplaces, hardware security protection strategies are crucial for protecting sensitive data and preventing unauthorized access. Personal devices such as tablets and laptops, measures like strong password policies, multi-factor authentication, device encryption, and regularly updated antivirus software ensure these devices remain secure. For network devices such as router, switches and servers, strategies such as implementing firewalls, enabling intrusion detection and prevention systems, and maintaining strict access control policies are crucial for safeguarding network integrity. Additionally, physical security measures, like securing the devices in access-controlled rooms or cabinets, reduce the risk of tampering or theft.   Backup Strategy   Regular backups play a crucial role in protecting data from unexpected events like hardware failures, cyberattacks, or accidental deletions. Their primary function is to ensure that critical...
